FIG. 1 is a perspective view of a camera module according to an embodiment of the present invention, and FIG. 2 is a schematic exploded perspective view of a camera module according to an embodiment of the present invention.

Referring to FIGS. 1 and 2, a camera module (1) according to an embodiment of the present invention may include an image sensor (S) according to an embodiment of the present invention, and may further include at least one of a lens module (700), a first actuator (10), and a second actuator (20).

The first actuator (10) may be an actuator for shake correction, and the second actuator (20) may be an actuator for focus adjustment, but is not limited thereto. For example, the first actuator (10) may be an actuator for shake correction and/or focus adjustment, and the second actuator (20) may be omitted. For example, the second actuator (20) may be an actuator for shake correction and/or focus adjustment, and the first actuator (10) may be omitted.

The lens module (700) may include at least one lens and a lens barrel (710). At least one lens may be arranged inside the lens barrel (710). When the number of the at least one lens is two or more, a plurality of lenses may be mounted inside the lens barrel (710) along the optical axis (Z-axis).

For example, the lens module (700) may further include a carrier (730) coupled with a lens barrel (710). The carrier (730) may be provided with a hollow portion penetrating the carrier (730) in the direction of the optical axis (Z-axis), and the lens barrel (710) may be inserted into the hollow portion and fixedly positioned relative to the carrier (730).

During auto focus (AF), the first actuator (10) and/or the second actuator (20) can move the lens module (700) in the direction of the optical axis (Z-axis), and the lens module (700) can adjust the focus.

In optical image stabilization (OIS), the first actuator (10) and/or the second actuator (20) can move the lens module (700) in a direction perpendicular to the optical axis (Z-axis) (e.g., X-axis and/or Y-axis), the lens module (700) can move within the camera module (1) in a direction that offsets the movement due to an external force of the camera module (1), and the image sensor (S) can reduce the influence of an external force of the camera module (1) on the image during the process of acquiring the image through the lens module (700).

Referring to FIGS. 1 and 2, the first actuator (10) may include at least one of a fixed frame (100), a movable frame (200), a first driving unit, a sensor substrate (400), and a base (500). The first driving unit may include first and second sub-driving units. The first sub-driving unit may include at least one of a first magnet (311), a first coil (313), and a first position sensor (315), and the second sub-driving unit may include at least one of a second magnet (331), a second coil (333), and a second position sensor (335).

The fixed frame (100) can be combined with the second actuator (20) described later. For example, the fixed frame (100) can be combined with the housing (600) of the second actuator (20). A mounting groove in which the housing (600) of the second actuator (20) is mounted can be provided on the upper surface of the fixed frame (100).

The fixed frame (100) may be a fixed member that does not move during focus adjustment and shake correction, and may have a square box shape with the top and bottom open, but is not limited thereto.

The movable frame (200) can be accommodated in the fixed frame (100). The fixed frame (100) has a side wall extending downward in the direction of the optical axis (Z-axis), and accordingly, the fixed frame (100) can have an accommodation space for accommodating the movable frame (200).

The movable frame (200) can be moved relative to the fixed frame (100) in a direction perpendicular to the optical axis (Z-axis) or rotated around the optical axis (Z-axis) as the rotation axis. That is, the movable frame (200) can be a movable member that moves during shake correction.

For example, the moving frame (200) is configured to be movable in the first axis (X-axis) direction and the second axis (Y-axis) direction, and can rotate about the optical axis (Z-axis) as the rotation axis. The first axis (X-axis) direction may mean a direction perpendicular to the optical axis (Z-axis), and the second axis (Y-axis) direction may mean a direction perpendicular to both the optical axis (Z-axis) direction and the first axis (X-axis) direction. The moving frame (200) may have a square plate shape with the center perforated in the optical axis (Z-axis) direction, but is not limited thereto.

An infrared cut filter (IRCF) may be mounted on the upper surface of the moving frame (200). A filter mounting groove in which an infrared cut filter (IRCF) is mounted may be provided on the upper surface of the moving frame (200). A sensor substrate (400) may be mounted on the lower surface of the moving frame (200).

A first ball member (B1) may be placed between the fixed frame (100) and the movable frame (200). The first ball member (B1) may be placed so as to contact the fixed frame (100) and the movable frame (200), respectively. When the movable frame (200) is moved or rotated relative to the fixed frame (100), the first ball member (B1) may roll between the fixed frame (100) and the movable frame (200) to support the movement of the movable frame (200). For example, in order to reinforce the rigidity of the movable frame (200), a reinforcing plate made of stainless steel may be provided on the movable frame (200).

An image sensor (S) may be mounted on the sensor substrate (400). A part of the sensor substrate (400) may be coupled with the moving frame (200), and another part of the sensor substrate (400) may be coupled with the fixed frame (100). An image sensor (S) may be mounted on a part of the sensor substrate (400) coupled with the moving frame (200).

For example, since a part of the sensor substrate (400) is coupled to the moving frame (200), as the moving frame (200) is moved or rotated, a part of the sensor substrate (400) can also be moved or rotated together with the moving frame (200). Accordingly, the image sensor (S) can be moved or rotated in a plane perpendicular to the optical axis (Z axis) to correct shaking during shooting.

For example, the sensor substrate (400) may be a rigid-flexible printed circuit board. For example, the image sensor (S) may be placed on a rigid portion of the rigid-flexible printed circuit board, and the flexible portion of the rigid-flexible printed circuit board may be electrically connected to a first driving unit to be described later, or may be electrically connected to an object (e.g., an IC, a processor) that transmits an image acquired by the image sensor (S). For example, a base (500) that can prevent foreign substances from entering may be coupled to a lower portion of the sensor substrate (400).

The first driving unit can generate a driving force in a direction perpendicular to the optical axis (Z-axis) to move the moving frame (200) in a direction perpendicular to the optical axis (Z-axis) or rotate the moving frame (200) about the optical axis (Z-axis) as a rotational axis. The first sub-driving unit of the first driving unit can generate a driving force in the direction of the first axis (X-axis), and the second sub-driving unit of the first driving unit can generate a driving force in the direction of the second axis (Y-axis).

The first magnet (311) and the first coil (313) of the first sub-driving unit may be arranged to face each other in the direction of the optical axis (Z-axis). The first magnet (311) may be arranged in the moving frame (200). The first magnet (311) may include a plurality of magnets. For example, the first magnet (311) may include two magnets, and the two magnets may be arranged symmetrically spaced apart from each other with respect to the optical axis (Z-axis). For example, the first magnet (311) may include two magnets that are spaced apart from each other in the direction in which the driving force is generated by the first magnet (311) (the direction of the first axis (X-axis)). For example, a mounting groove in which the first magnet (311) is arranged may be provided on the upper surface of the moving frame (200).

The first magnet (311) can be magnetized so that one surface (e.g., the surface facing the first coil (313)) has both an N pole and a S pole. For example, the surface of the first magnet (311) facing the first coil (313) can be provided with an N pole, a neutral region, and a S pole in sequence along the first axis (X-axis) direction. The first magnet (311) can have a shape having a length in the second axis (Y-axis) direction. The other surface of the first magnet (311) (e.g., the surface opposite the one surface) can be magnetized so that it has both an S pole and a N pole. For example, the other surface of the first magnet (311) can be provided with an S pole, a neutral region, and a N pole in sequence along the first axis (X-axis) direction.

The first coil (313) may be arranged to face the first magnet (311). For example, the first coil (313) may be arranged to face the first magnet (311) in the direction of the optical axis (Z-axis). The first coil (313) may have a donut shape with a hollow portion and may have a shape having a length in the direction of the second axis (Y-axis). The first coil (313) may include a number of coils corresponding to the number of magnets included in the first magnet (311).

The first coil (313) may be placed on the first substrate (350). The first substrate (350) may be mounted on the fixed frame (100) so that the first magnet (311) and the first coil (313) face each other in the direction of the optical axis (Z-axis). The fixed frame (100) may be provided with a through hole. For example, the through hole may be configured to penetrate the upper surface of the fixed frame (100) in the direction of the optical axis (Z-axis), and the upper portion of the through hole may be covered by the first substrate (350).

The first magnet (311) is a movable member mounted on the movable frame (200) and moves together with the movable frame (200), and the first coil (313) may be a fixed member fixed to the first substrate (350) and the fixed frame (100). When power is applied to the first coil (313), the movable frame (200) can be moved in the first axis (X-axis) direction by the electromagnetic force between the first magnet (311) and the first coil (313). The first magnet (311) and the first coil (313) can generate a driving force in a direction perpendicular to the direction in which they face each other (optical axis direction) (for example, in the first axis (X-axis) direction).

The second magnet (331) and the second coil (333) of the second sub-driving unit may be arranged to face each other in the direction of the optical axis (Z-axis). The second magnet (331) may be arranged in the moving frame (200). The second magnet (331) may include a plurality of magnets. For example, the second magnet (331) may include two magnets, and the two magnets may be arranged to be spaced apart from each other along the first axis (X-axis) direction. For example, the second magnet (331) may include two magnets that are arranged to be spaced apart from each other in a direction perpendicular to the direction in which the driving force is generated by the second magnet (331) (the second axis (Y-axis) direction).

According to the design, the first magnet (311) and the second magnet (331) may be arranged opposite to each other in the form illustrated in FIG. 2. For example, the first magnet (311) may include two magnets spaced apart in a direction perpendicular to the direction in which the driving force is generated by the first magnet (311) (the first axis (X-axis) direction), and the second magnet (331) may include two magnets spaced apart in a direction in which the driving force is generated by the second magnet (331) (the second axis (Y-axis) direction). Alternatively, both the first magnet (311) and the second magnet (331) may include two magnets spaced apart in a direction perpendicular to the direction in which the driving force is generated by each magnet. A mounting groove in which the second magnet (331) is arranged may be provided on an upper surface of the moving frame (200).

The second magnet (331) can be magnetized so that one surface (e.g., the surface facing the second coil (333)) has both a S pole and a N pole. For example, a S pole, a neutral region, and a N pole may be sequentially provided on one surface of the second magnet (331) facing the second coil (333) along the second axis (Y-axis). The second magnet (331) may have a shape having a length in the first axis (X-axis) direction. The other surface of the second magnet (331) (e.g., the opposite surface of the one surface) may be magnetized so that it has both a N pole and a S pole. For example, the other surface of the second magnet (331) may be sequentially provided with a N pole, a neutral region, and a S pole along the second axis (Y-axis).

The second coil (333) may be arranged to face the second magnet (331). For example, the second coil (333) may be arranged to face the second magnet (331) in the direction of the optical axis (Z-axis). The second coil (333) may have a hollow donut shape and may have a shape having a length in the direction of the first axis (X-axis). The second coil (333) may include a number of coils corresponding to the number of magnets included in the second magnet (331).

The second coil (333) may be placed on the first substrate (350). The first substrate (350) may be mounted on the fixed frame (100) so that the second magnet (331) and the second coil (333) face each other in the optical axis (Z-axis) direction. The fixed frame (100) may be provided with a through hole. For example, the through hole may be configured to penetrate the upper surface of the fixed frame (100) in the optical axis direction, and the second coil (333) may be placed in the through hole of the fixed frame (100).

The second magnet (331) is a movable member mounted on the movable frame (200) and moves together with the movable frame (200), and the second coil (333) may be a fixed member fixed to the first substrate (350) and the fixed frame (100). When power is applied to the second coil (333), the movable frame (200) can be moved in the second axis (Y-axis) direction by the electromagnetic force between the second magnet (331) and the second coil (333). The second magnet (331) and the second coil (333) can generate a driving force in a direction perpendicular to the direction in which they face each other (optical axis direction) (for example, the second axis (Y-axis) direction).

Meanwhile, the moving frame (200) can be rotated around the optical axis (Z axis) by the first and second magnets (311, 331) and the first and second coils (313, 333).

A first ball member (B1) may be placed between the fixed frame (100) and the movable frame (200). The first ball member (B1) may be placed so as to contact the fixed frame (100) and the movable frame (200), respectively. The first ball member (B1) may guide the movement of the movable frame (200) during the shake correction process, and may also maintain a gap between the fixed frame (100) and the movable frame (200).

The first ball member (B1) can roll in the first axis (X-axis) direction when a driving force is generated in the first axis (X-axis) direction. Accordingly, the first ball member (B1) can guide the movement of the movable frame (200) in the first axis (X-axis) direction. In addition, the first ball member (B1) can roll in the second axis (Y-axis) direction when a driving force is generated in the second axis (Y-axis) direction. Accordingly, the first ball member (B1) can guide the movement of the movable frame (200) in the second axis (Y-axis) direction. The first ball member (B1) may include a plurality of balls arranged between the fixed frame (100) and the movable frame (200).

At least one of the surfaces of the fixed frame (100) and the movable frame (200) facing each other in the direction of the optical axis (Z-axis) may be provided with a guide groove in which a first ball member (B1) is arranged. A plurality of guide grooves may be provided to correspond to the plurality of balls of the first ball member (B1). For example, a first guide groove may be provided on a lower surface of the fixed frame (100), and a second guide groove may be provided on an upper surface of the movable frame (200). The first ball member (B1) may be arranged in the first guide groove and the second guide groove and may be inserted between the fixed frame (100) and the movable frame (200).

The first position sensor (315) may be arranged on the first substrate (350) to face the first magnet (311), and the second position sensor (335) may be arranged on the first substrate (350) to face the second magnet (331). For example, the first position sensor (315) and the second position sensor (335) may be Hall sensors. For example, the second position sensor (335) may include two Hall sensors. For example, the second magnet (331) may include two magnets spaced apart in a direction (the first axis (X-axis) direction) perpendicular to a direction in which a driving force is generated by the second magnet (331) (the second axis (Y-axis) direction), and the second position sensor (335) may include two Hall sensors arranged to face the two magnets. Through two Hall sensors facing the second magnet (331), it is possible to detect whether the moving frame (200) is rotating.

Referring to FIGS. 1 and 2, the first actuator (10) may include a first yoke (317) and a second yoke (337). The first yoke (317) and the second yoke (337) may provide a force to allow the fixed frame (100) and the movable frame (200) to maintain contact with the first ball member (B1).

The first yoke (317) and the second yoke (337) may be placed on the fixed frame (100). For example, the first yoke (317) and the second yoke (337) may be placed on the first substrate (350), and the first substrate (350) may be coupled to the fixed frame (100). The first coil (313) and the second coil (333) may be placed on one surface of the first substrate (350), and the first yoke (317) and the second yoke (337) may be placed on the other surface of the first substrate (350). For example, the first yoke (317) and the second yoke (337) may be made of a material that can generate an attractive force between the first magnet (311) and the second magnet (331). For example, the first yoke (317) and the second yoke (337) may be provided as magnetic materials.

The first yoke (317) may be arranged to face the first magnet (311) in the direction of the optical axis (Z-axis). The first yoke (317) may include a plurality of yokes corresponding to twice the number of magnets included in the first magnet (311). For example, each magnet of the first magnet (311) may face two yokes in the direction of the optical axis (Z-axis). The two yokes facing one magnet may be arranged spaced apart from each other in the direction of the second axis (Y-axis). However, it is also possible for the first yoke (317) to include a plurality of yokes corresponding to the number of magnets included in the first magnet (311).

The second yoke (337) may be arranged to face the second magnet (331) in the optical axis (Z-axis) direction. The second yoke (337) includes a plurality of yokes corresponding to the number of magnets included in the second magnet (331). For example, when the second magnet (331) includes two magnets, the second yoke (337) may include two yokes. The two yokes may be spaced apart from each other in the first axis (X-axis) direction. Alternatively, each magnet of the second magnet (331) may face two yokes in the optical axis direction. In this case, the two yokes facing one magnet may be spaced apart from each other in the first axis (X-axis) direction.

Referring to FIGS. 1 and 2, the second actuator (20) may include at least one of a case (630), a carrier (730), a housing (600), and a second driving unit. The second driving unit may include at least one of a third magnet (810), a third coil (830), a third position sensor (850), a third yoke (870), and a second substrate (890).

The carrier (730) may be provided with a hollow portion penetrating the carrier (730) in the direction of the optical axis (Z-axis), and the lens barrel (710) is inserted into the hollow portion and fixedly positioned relative to the carrier (730). Accordingly, the lens barrel (710) and the carrier (730) can move together in the direction of the optical axis (Z-axis).

The housing (600) has an internal space and may be a square box shape with an open top and bottom. The carrier (730) may be placed in the internal space of the housing (600). The case (630) may be configured to be combined with the housing (600) and protect the internal configuration of the second actuator (20).

The third magnet (810) and the third coil (830) of the second driving unit (800) can generate a driving force in the direction of the optical axis (Z-axis) to move the carrier (730) (2000) in the direction of the optical axis (Z-axis). The third magnet (810) and the third coil (830) can be arranged to face each other in a direction perpendicular to the optical axis (Z-axis).

The third magnet (810) may be placed on the carrier (730). For example, the third magnet (810) may be placed on one side of the carrier (730). A back yoke may be placed between the carrier (730) and the third magnet (810). The third magnet (810) may be magnetized so that one side (e.g., the side facing the third coil (830)) has both an N pole and a S pole. For example, one side of the third magnet (810) facing the third coil (830) may be provided with an N pole, a neutral region, and a S pole in sequence along the optical axis (X-axis). The other side (e.g., the opposite side of the one side) of the third magnet (810) may be magnetized so that it has both an S pole and an N pole. For example, the other side of the third magnet (810) may be provided with a south pole, a neutral region, and a north pole in sequence along the optical axis (X-axis).

The third coil (830) is positioned to face the third magnet (810). For example, the third coil (830) may be positioned to face the third magnet (810) in a direction perpendicular to the optical axis (Z-axis). The third coil (830) may be positioned on the second substrate (890), and the second substrate (890) may be mounted on the housing (600) such that the third magnet (810) and the third coil (830) face each other in a direction perpendicular to the optical axis (Z-axis).

The third magnet (810) is a moving member mounted on the carrier (730) and moves in the direction of the optical axis (Z-axis) together with the carrier (730), and the third coil (830) may be a fixed member fixed to the second substrate (890). When power is applied to the third coil (830), the carrier (730) can be moved in the direction of the optical axis (Z-axis) by the electromagnetic force between the third magnet (810) and the third coil (830). Since the lens barrel (710) is arranged on the carrier (730), the lens barrel (710) can also be moved in the direction of the optical axis (Z-axis) by the movement of the carrier (730).

A third yoke (870) may be arranged in the housing (600). The third yoke (870) may be arranged at a position facing the third magnet (810). For example, a third coil (830) may be arranged on one surface of the first substrate (350), and the third yoke (870) may be arranged on the other surface of the first substrate (350). The third magnet (810) and the third yoke (870) may generate an attractive force between each other. For example, an attractive force acts in a direction perpendicular to the optical axis (Z-axis) between the third magnet (810) and the third yoke (870).

Guide grooves may be arranged on surfaces where the carrier (730) and the housing (600) face each other. For example, the carrier (730) may be provided with a third guide groove, and the housing (600) may be provided with a fourth guide groove. The first ball group (BG1) and the second ball group (BG2) may be arranged in the third and fourth guide grooves, and may each include a plurality of balls.

The third position sensor (850) is placed on the second substrate (890) so as to face the third magnet (810). For example, the third position sensor (850) may be a Hall sensor.

Referring to FIGS. 1 to 4, an image sensor (S) according to an embodiment of the present invention may be placed in a placement space provided by a sensor substrate (400) of a first actuator (10). A lens module (700) of a second actuator (20) may be placed on the image sensor (S) and may be placed on the sensor substrate (400). A camera module (1) according to an embodiment of the present invention may include a sensor substrate (400) and a lens module (700).

The angle of view of the lens module (700) may be θ. When the focus of the lens module (700) is adjusted, the distance in the optical axis direction between the arrangement space of the image sensor (S) and the lens module (700) may be F. The radius of the lens optical size (LOS) may be calculated as {tan(θ/2) * F}, and the diameter may be calculated as {2 * tan(θ/2) * F}.

The image sensor (S) may include a plurality of pixels (see FIG. 8) arranged with a predetermined aspect ratio (AR_S) to sense an image in the direction of an optical axis (Z-axis). The image sensed by the image sensor (S) may be limited within a lens optical size (LOS). Therefore, as the lens optical size (LOS) increases, the size or angle of view of the image sensed by the image sensor (S) may become wider, and the degree of freedom in selecting the aspect ratio of the image sensed by the image sensor (S) may become wider. Furthermore, the size or angle of view of a display image of an electronic device using the image sensor (S) may also become wider, and the degree of freedom in selecting the aspect ratio may also become wider.

The lens optical size (LOS) can increase as the angle of view (θ) increases or the distance (F) increases. Accordingly, when the Z-direction length of the lens module (700) increases or the Z-direction length of the entire camera module (1) increases, the lens optical size (LOS) can increase.

The Z-direction length of the lens module (700) or the Z-direction length of the entire camera module (1) may be limited according to the specifications required for the camera module (1) or the specifications required for an electronic device using an image sensor (S). In this case, the maximum size of the lens optical size (LOS) may also be limited.

Accordingly, the lens module (700) of the camera module (1) according to one embodiment of the present invention may be placed on the sensor substrate (400) such that {2 * tan(θ/2) * F} is shorter than DL, which is the length from one corner of one longitudinal and transverse end of the image sensor (S) to the other corner of the other longitudinal and transverse ends.

Alternatively, a predetermined aspect ratio (AR_S) of the image sensor (S) may be higher than the first aspect ratio (AR_1) and lower than the second aspect ratio (AR_2). Here, the first aspect ratio (AR_1) may be 4/3, and the second aspect ratio (AR_2) may be 16/9. For example, the lens module (700) may be in a state where the focus is adjusted so that the image sensor (S) senses an image of the first aspect ratio (AR_1) and/or the second aspect ratio (AR_2), and {2 * tan(θ/2) * F} may be less than or equal to the length (DL).

The aspect ratio of an image that an electronic device using an image sensor (S) intends to obtain may likely be 4/3 or 16/9. For example, if the electronic device intends to obtain an image with a first aspect ratio (AR_1), an area from which the image sensor (S) obtains an image may be an area from which one longitudinal end area and one longitudinal end area are excluded from the entire area of the image sensor (S). For example, if the electronic device intends to obtain an image with a second aspect ratio (AR_2), an area from which the image sensor (S) obtains an image may be an area from which one transverse end area and one transverse end area are excluded from the entire area of the image sensor (S).

Here, the sum of the total area of the region excluded to obtain an image of the first aspect ratio (AR_1) and the total area of the region excluded to obtain an image of the second aspect ratio (AR_2) may be smaller when the predetermined aspect ratio (AR_S) of the image sensor (S) is higher than the first aspect ratio (AR_1) and lower than the second aspect ratio (AR_2), compared to when the predetermined aspect ratio (AR_S) of the image sensor (S) is the first aspect ratio (AR_1) or the second aspect ratio (AR_2).

Accordingly, the image sensor (S) according to one embodiment of the present invention can efficiently expand the overall area of images of the first and second aspect ratios (AR_1, AR_2), and can also prevent one of the images of the first and second aspect ratios (AR_1, AR_2) from becoming too small.

The corner (CN) of the image sensor (S) may belong to both the area excluded for obtaining an image of the first aspect ratio (AR_1) and the area excluded for obtaining an image of the second aspect ratio (AR_2). Accordingly, the corner (CN) of the image sensor (S) may not need to be within the lens optical size (LOS), and the Z-direction length of the lens module (700) or the Z-direction length of the entire camera module (1) may be shortened.

For example, a pixel closest to a corner (CN) of an image sensor (S) may not need to be used for image sensing, and thus may be in a deactivated state. On the other hand, a pixel closest to the center of the image sensor (S) may be used for image sensing, and thus may be in an activated state. Since the power consumption of a pixel in a deactivated state may be lower, the image sensor (S) may reduce the overall power consumption through the pixel in a deactivated state. For example, deactivating a pixel may mean lowering a power voltage supplied to the pixel (see FIGS. 9A and 9B), and activating a pixel may mean that the power voltage supplied to the pixel is normal.

For example, the given aspect ratio (AR_S) can be greater than 16/11.5 and less than 16/9.5. For example, the given aspect ratio (AR_S) can be 16/10 or 16/11.

For example, the image sensor (S) can sense images of a third aspect ratio (AR_3) and/or a fourth aspect ratio (AR_4). The third aspect ratio (AR_3) can be 20/9, and the fourth aspect ratio (AR_4) can be 21/9. The third and fourth aspect ratios (AR_3, AR_4) can be higher than the given aspect ratio (AR_S). Since the third and fourth aspect ratios (AR_3, AR_4) can be higher than the second aspect ratio (AR_2), the images of the third and fourth aspect ratios (AR_3, AR_4) can have a considerably wide horizontal angle of view.

The lens optical size (LOS) can be circular, and a predetermined aspect ratio (AR_S) greater than 16/11.5 and less than 16/9.5 can efficiently provide images of first, second, third and fourth aspect ratios (AR_1, AR_2, AR_3, AR_4) in the lens optical size (LOS).

Table 1 below shows parameters of six exemplary embodiments of an image sensor (S) according to one embodiment of the present invention. The six exemplary embodiments can satisfy a requirement that the z-direction length of the lens module (700) is less than 9 mm, and can provide an image having a horizontal angle of view wider than 120 degrees, a vertical angle of view wider than 90 degrees, and an optical distortion amount of less than 3%.

The number of pixels in Table 1 (e.g., 116M, 120M) may be set so that a frame rate of 24fps or higher can be stably secured when the image sensor (S) provides a video image, but is not limited thereto. The number of pixels in Table 1 may be the product of the number of horizontal pixels and the number of vertical pixels. For example, when the number of pixels of the image sensor (S) is 116M, the number of pixels used for an image of the first aspect ratio (AR_1) may be 100MP, the number of pixels used for an image of the second aspect ratio (AR_2) may be 92MP, the number of pixels used for an image of the third aspect ratio (AR_3) may be 80MP, and the number of pixels used for an image of the fourth aspect ratio (AR_4) may be 76MP. For example, the structure of a plurality of pixels of the six exemplary embodiments of Table 1 may be a 2*2 tetra color filter array structure.

For example, referring to Table 1, the length DL from one corner of one longitudinal and transverse end of the image sensor (S) according to one embodiment of the present invention to the other corner of the other longitudinal and transverse end may be greater than 8 mm and less than 14.4 mm.

For example, referring to Table 1, the longitudinal length or transverse length of each of the plurality of pixels of the image sensor (S) according to one embodiment of the present invention may be greater than 0.5 μm and less than 0.9 μm.

For example, referring to Table 1, {2 * tan(θ/2) * F} of the camera module (1) according to one embodiment of the present invention may be (16/1.85) mm or more and (16/1.3) mm or less.

FIG. 5 is a plan view illustrating aspect ratios that can be selected among various aspect ratios of FIG. 4 when optical image stabilization (OIS) is used.

Referring to FIG. 5, in the optical image stabilization (OIS) mode, the second and fourth aspect ratios (AR_2, AR_4) may be used, and the first and third aspect ratios (AR_1, AR_3) of FIG. 4 may not be used. Whether the first and third aspect ratios (AR_1, AR_3) are used may vary depending on whether OIS is used. The aspect ratio that varies depending on whether OIS is used may vary depending on the design.

For example, since the longitudinal one end area, the longitudinal other end area, the transverse one end area, and the transverse other end area of the image sensor (S) may not be used for sensing the image of the second aspect ratio (AR_2), the margin for OIS of the image of the second aspect ratio (AR_2) may be wider or more balanced than that of the other aspect ratios. Accordingly, the image of the second aspect ratio (AR_2) can be acquired more stably according to OIS.

For example, since an image of the fourth aspect ratio (AR_4) may have the widest horizontal field of view, it may be more likely to be optimized than images of other aspect ratios, and the high optimization of the image of the fourth aspect ratio (AR_4) may also make it efficient for OIS. Accordingly, the image of the fourth aspect ratio (AR_4) may also be acquired more stably with OIS.

For example, a relatively wide horizontal field of view, such as the fourth aspect ratio (AR_4), may require a maximum distance that the sensor substrate (400) or lens module (700) can move for OIS to be longer than that of a typical OIS. For example, the OIS horizontal correction angle and the OIS vertical correction angle may be 3 degrees or more and 5 degrees or less, respectively, and the OIS diagonal correction angle may be 4 degrees or more and 7 degrees or less.

For example, if the maximum distance that the sensor substrate (400) or the lens module (700) can move from a point corresponding to the center of the lens optical size (LOS) for OIS is [{tan(θ/2) * F} - {tan((θ/2) - B) * F}], the B may be an OIS diagonal correction angle. Accordingly, B may be 4 degrees or more and 7 degrees or less.

FIGS. 6A and 6B are plan views illustrating the range of images acquired by an image sensor according to one embodiment of the present invention when electronic image stabilizing (EIS) is used instead of optical image stabilization (OIS).

Referring to FIGS. 6a and 6b, OIS can be replaced with electronic image stabilization (EIS).

For example, referring to FIG. 6a, a center region (CC_large, CC_small), a transverse end region (LC_large, LC_small), a transverse other end region (RC_large, RC_small), a longitudinal one end region (UC_large, UC_small), and a longitudinal other end region (BC_large, BC_small) can be sensed primarily, and the transverse one end region (LC_large, LC_small), the transverse other end region (RC_large, RC_small), the longitudinal one end region (UC_large, UC_small), and the longitudinal other end region (BC_large, BC_small) can be cropped. Accordingly, the center region (CC_large, CC_small) can have an image with a second aspect ratio (AR_2).

For example, referring to FIG. 6b, a center region (CC_large, CC_small), a transverse end region (LC_large, LC_small), a transverse other end region (RC_large, RC_small), a longitudinal one end region (UC_large, UC_small), and a longitudinal other end region (BC_large, BC_small) can be sensed primarily, and the transverse one end region (LC_large, LC_small), the transverse other end region (RC_large, RC_small), the longitudinal one end region (UC_large, UC_small), and the longitudinal other end region (BC_large, BC_small) can be cropped. Accordingly, the center region (CC_large, CC_small) can have an image with a fourth aspect ratio (AR_4).

The transverse one end region (LC_large, LC_small), the transverse other end region (RC_large, RC_small), the longitudinal one end region (UC_large, UC_small), and the longitudinal other end region (BC_large, BC_small) of FIG. 6a can be aligned to the second aspect ratio (AR_2), and the transverse one end region (LC_large, LC_small), the transverse other end region (RC_large, RC_small), the longitudinal one end region (UC_large, UC_small), and the longitudinal other end region (BC_large, BC_small) of FIG. 6b can be aligned to the fourth aspect ratio (AR_4). Thus, the transverse one-end region (LC_large, LC_small), the transverse other-end region (RC_large, RC_small), the longitudinal one-end region (UC_large, UC_small) and the longitudinal other-end region (BC_large, BC_small) can be determined based on a selection from among multiple aspect ratios (e.g., the second and fourth aspect ratios).

FIG. 7 is a plan view illustrating that image sensors according to one embodiment of the present invention acquire images having the same aspect ratio and different sizes.

Referring to FIG. 7, a large image (AR_1_large) of the first aspect ratio can be larger than a small image (AR_1_small) of the first aspect ratio. For example, the large image (AR_1_large) and the small image (AR_1_small) can be selectively sensed, and one of the two can be used for video image sensing and the other can be used for photo image sensing.

For example, the number of pixels and the horizontal field of view used for sensing a large image (AR_1_large) may be 100M and 100 degrees, and the number of pixels and the horizontal field of view used for sensing a small image (AR_1_small) may be 48M and 70 degrees.

FIG. 8 is a block diagram simply illustrating an image sensor according to one embodiment of the present invention.

Referring to FIG. 8, the image sensor (S) may include a plurality of pixels (PX) arranged in an array form along a plurality of rows and a plurality of columns. Each of the plurality of pixels (PX) may include at least one photoelectric conversion element that generates a charge in response to light, and a pixel circuit that generates a pixel signal corresponding to the charge generated by the photoelectric conversion element. The photoelectric conversion element may include a photodiode formed of a semiconductor material, and/or an organic photodiode formed of an organic material.

For example, the pixel circuit may include a floating diffusion, a transfer transistor, a reset transistor, a driving transistor, and a selection transistor. The configuration of the pixels (PX) may vary depending on the embodiments. For example, each of the pixels (PX) may include an organic photodiode including an organic material, or may be implemented as a digital pixel. When the pixels (PX) are implemented as digital pixels, each of the pixels (PX) may include an analog-to-digital converter for outputting a digital pixel signal.

Referring to FIG. 8, the IC may include circuits for controlling the image sensor (S). For example, the IC may include a row driver (21), a readout circuit (22), a column driver (23), control logic (24), etc. The row driver (21) may drive a plurality of pixels (PX) in units of row lines. For example, the row driver (21) may generate a transmission control signal for controlling a transmission transistor of a pixel circuit, a reset control signal for controlling a reset transistor, a selection control signal for controlling a selection transistor, etc., and input them to a plurality of pixels (PX) in units of row lines.

The readout circuit (22) may include a correlated double sampler (CDS), an analog-to-digital converter (ADC), etc. The correlated double samplers may be connected to a plurality of pixels (PX) through column lines. The correlated double samplers may read pixel signals from a plurality of pixels (PX) connected to a row line selected by a row line selection signal of a row driver (21) through the column lines. The analog-to-digital converter may convert a pixel signal detected by the correlated double sampler into a digital pixel signal and transmit the digital pixel signal to the column driver (23).

The column driver (23) may include a latch or buffer circuit and an amplifier circuit that can temporarily store a digital pixel signal, and may process a digital pixel signal received from the readout circuit (22). The row driver (21), the readout circuit (22), and the column driver (23) may be controlled by a control logic (24). The control logic (24) may include a timing controller for controlling the operation timing of the row driver (21), the readout circuit (22), and the column driver (23).

Among the plurality of pixels (PX), pixels (PX) arranged at the same position in the horizontal direction can share the same column line. For example, pixels (PX) arranged at the same position in the vertical direction can be simultaneously selected by the row driver (21) and output pixel signals through the column lines. In one embodiment, the readout circuit (22) can simultaneously obtain pixel signals from pixels (PX) selected by the row driver (21) through the column lines. The pixel signal can include a reset voltage and a pixel voltage, and the pixel voltage can be a voltage in which charges generated in response to light in each of the pixels (PX) are reflected in the reset voltage.

The spacing (PL) between the plurality of pixels (PX) may correspond to each longitudinal length or transverse length of the plurality of pixels (PX), and may be greater than 0.5 μm and less than 0.9 μm, but is not limited thereto.

FIGS. 9A and 9B are drawings simply illustrating a pixel circuit of an image sensor according to one embodiment of the present invention.

First, referring to FIG. 9A, each of the plurality of pixels (PX) includes a photodiode (PD) and a pixel circuit, and the pixel circuit may include a transmission transistor (TX), a reset transistor (RX), a selection transistor (SX), and a driving transistor (DX). In addition, the pixel circuit may include a floating diffusion region (FD) in which charges generated from the photodiode (PD) are accumulated.

A photodiode (PD) can generate and accumulate charges in response to externally incident light. The photodiode (PD) may be replaced with a phototransistor, a photogate, a pinned photodiode, etc., according to embodiments. A transfer transistor (TX) can move charges generated in the photodiode (PD) to a floating diffusion region (FD). The floating diffusion region (FD) can store charges generated in the photodiode (PD). A voltage output by a driving transistor (DX) can vary depending on the amount of charges accumulated in the floating diffusion region (FD).

The reset transistor (RX) can reset the voltage of the floating diffusion region (FD) by removing charges accumulated in the floating diffusion region (FD). The drain electrode of the reset transistor (RX) is connected to the floating diffusion region (FD), and the source electrode can be connected to a power supply voltage (VDD). When the reset transistor (RX) is turned on, the power supply voltage (VDD) connected to the source electrode of the reset transistor (RX) is applied to the floating diffusion region (FD), and the reset transistor (RX) can remove charges accumulated in the floating diffusion region (FD).

The driving transistor (DX) can operate as a source follower buffer amplifier. The driving transistor (DX) can amplify a voltage change of a floating diffusion region (FD) and output it to one of the column lines (COL1, COL2). The selection transistor (SX) can select pixels (PX) to be read in units of rows. When the selection transistor (SX) is turned on, the voltage of the driving transistor (DX) can be output to one of the column lines (COL1, COL2). For example, when the selection transistor (SX) is turned on, a reset voltage or a pixel voltage can be output through the column lines (COL1, COL2).

In one embodiment illustrated in FIG. 9a, each of the plurality of pixels (PX) may include a photodiode (PD) and a transmission transistor (TX), as well as a reset transistor (RX), a selection transistor (SX), and a driving transistor (DX). On the other hand, in one embodiment illustrated in FIG. 9b, two or more adjacent pixels may share at least some of the transistors included in the pixel circuit.

For example, the first photodiode (PD1) and the first transfer transistor (TX1) of the first pixel may be connected to the floating diffusion region (FD). Similarly, the second to fourth photodiodes (PD2-PD4) of the second to fourth pixels (PX2-PX4) may be connected to the floating diffusion region (FD) via the second to fourth transfer transistors (TX2-TX4). For example, the floating diffusion regions (FD) included in each of the pixels may be connected to each other using a wiring pattern or the like, so that the first to fourth transfer transistors (TX1-TX4) may be commonly connected to one floating diffusion region (FD).

Meanwhile, the pixel circuit may include a reset transistor (RX), first and second driving transistors (DX1, DX2), and a selection transistor (SX). The reset transistor (RX) may be controlled by a reset control signal (RG), and the selection transistor (SX) may be controlled by a selection control signal (SEL). For example, each of the four pixels may include one more transistor in addition to the transmission transistor (TX). Of the four transistors included in the four pixels, two may be configured to be connected in parallel to each other to provide the first and second driving transistors (DX1, DX2), and one of the remaining two transistors may be configured to provide the selection transistor (SX) and the other may be configured to provide the reset transistor (RX).

However, the pixel circuit described with reference to FIG. 9b is only one embodiment and is not necessarily limited to this form. For example, one of the four transistors may be assigned as a driving transistor and one may be assigned as a selection transistor. In addition, by connecting the remaining two in series and assigning them as the first and second reset transistors, an image sensor capable of controlling the conversion gain of the pixel may be implemented. Alternatively, the pixel circuit may vary depending on the number of transistors included in each pixel.

FIGS. 10 and 11 are diagrams illustrating an electronic device including a camera module according to one embodiment of the present invention.

Referring to FIGS. 10 and 11, an electronic device (ED) including a camera module (1) according to an embodiment of the present invention may include an image sensor (S) according to an embodiment of the present invention and may include at least one of an IC and a display member (DP).

The IC can receive image information sensed by the image sensor (S) and generate display image information based on the image.

The display member (DP) can output a display image. For example, the display member (DP) can output a display image of an aspect ratio selected from among a plurality of different aspect ratios. For example, the plurality of different aspect ratios can include at least three of 4/3, 16/9, 20/9, and 21/9.

For example, the display element (DP) can output a display image having a first aspect ratio (e.g., 4/3) lower than a predetermined aspect ratio (e.g., 16/10, 16/11) of the image sensor (S) and a second aspect ratio (e.g., 16/9, 20/9, 21/9) higher than the predetermined aspect ratio.

For example, the difference between different aspect ratios (e.g., 4/3, 16/9, 20/9, 21/9) may be greater than the difference between an aspect ratio (e.g., 3 aspect ratio (AR_3)) that is closer to the aspect ratio of the display member (DP) among the different aspect ratios (e.g., same as the third aspect ratio (AR_3)) and the aspect ratio of the display member. The aspect ratio of the display member (DP) may be a value obtained by dividing the major axis length (ML of AR_3) by the minor axis length (SL of AR_3).

For example, the display member (DP) may include at least one of a display cover member (91), a touch sensor panel (92), and a display panel (93). The display cover member (91) may be transparent, such as glass, and configured to protect the display member (DP) from external impact. The touch sensor panel (92) may detect a touch of a user of an electronic device, and may include a wire (82). The display panel (93) may output a display image, and may include a wire (83).

For example, the display member (DP) may be arranged to overlap the optical axis (Z axis) of the camera module (1) to output a display image with a relatively wide aspect ratio. For example, a structure that may be used for OIS correction in the camera module (1) may move the camera module (1) so that the camera module (1) can sense the image while avoiding the wires (82, 83). Since one side of the electronic device (ED) may be wider than one side of the display member (DP), the camera module (1) may not overlap the optical axis (Z axis) of the display member (DP) depending on the design.

For example, the IC may include at least one of a processor (71), a controller (72), and a driver (73), and may be electrically connected to the image sensor (S). For example, when the sensor substrate on which the image sensor (S) is disposed is a flexible printed circuit board, the IC may be flexibly electrically connected to the image sensor (S) through a flexible portion of the flexible printed circuit board.

For example, the processor (71) can perform information processing for the overall operation of the electronic device (ED), the controller (72) can perform information processing for the overall control of the image sensor (S), and the driver (73) can output a signal (e.g., current flowing in a coil) for the movement of the camera module (1).

For example, the IC may determine whether to use an OIS mode that moves a lens module or a sensor substrate to stabilize an image (image information) sensed by an image sensor (S), and may determine whether to use at least some of a plurality of aspect ratios (e.g., 4/3, 20/9) based on whether to use the OIS mode.

For example, the IC can crop a longitudinal one-end region, a longitudinal other-end region, a transverse one-end region, and a transverse other-end region of an image (Image information) sensed by an image sensor (S) in order to perform EIS processing. Here, the longitudinal one-end region, the longitudinal other-end region, the transverse one-end region, and the transverse other-end region can be determined based on a selection from among a plurality of aspect ratios (e.g., 16/9, 21/9).

Although the present invention has been described above with specific details such as specific components and limited examples and drawings, these have been provided only to help a more general understanding of the present invention, and the present invention is not limited to the above examples, and those with common knowledge in the technical field to which the present invention belongs can make various modifications and variations from this description.
