Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile phone or a portable information communication terminal device having an image pickup function, for example, a digital camera function.

[0002]

2. Description of the Related Art At present, portable telephones are not only used for voice conversation and data communication, but also have been provided on the market with models having a value-added function. This value-added function includes a digital camera function that has a function of photographing a subject. Such a camera function is not limited to a mobile phone, but has been installed in a mini notebook personal computer (hereinafter referred to as a PC) as a portable information communication terminal device.

At present, there are some types of cameras for mobile phones, including a type in which a camera module is externally attached to the main body and a type in which the main body is built in. However, the PDA (P
For the Personal Data Assistant device, only an external type of camera module is commercially available. The mini-notebook PC described above is provided with a camera portion that can be manually rotated in a desired direction. This PC is rotated so as to hide the camera lens when protecting the camera lens.

[0004]

However, since the cellular phone and the PDA device are becoming smaller than the mini-notebook PC, there is no room to install a mechanism for protecting the camera lens. Therefore, in these devices, the camera lens is protected by forming a recess that is deeper than the surrounding housing. Under these circumstances, it is not easy to provide a compact and multifunctional camera lens when accommodating the camera lens as a wider variety of camera functions.

In addition, information communication terminal devices including mobile phones and PDA devices have recently been increasingly demanded as information terminal devices in electronic commerce. The information communication terminal device is required to have an important authentication function for determining whether or not the user currently in use is the person himself / herself. In authentication of electronic commerce, information such as a password negotiated in advance may be easily read by a hacker and may be misused. Authentication requires the reliable identification of individuals, as in electronic commerce. In particular,
The information communication terminal device may be lost due to its downsizing, for example. In such a case, it is desired that the information communication terminal device should not be operated by the finder.

Regarding the security of such an information communication terminal device, there is a security system and method for a portable telephone device described in, for example, Japanese Patent Laid-Open No. 2000-307715. In this system, the camera unit captures the biometric information unique to the user, and the biometric information stored in the authentication unit is compared to ensure security. However, there is no description such as focus adjustment associated with photographing biological information by the camera unit.

Regarding the photographing, in the camera-equipped mobile phone disclosed in Japanese Patent Laid-Open No. 2001-333171, when the general built-in photographing and the enlarged photographing of the user's iris associated with personal authentication are performed by the built-in camera, Since the focal positions are remarkably different, a movable lens is provided in front of the existing objective lens to move the movable lens on the slide rail, and the focal position is changed according to whether or not the movable lens is inserted. However, this mobile phone does not describe a mechanism for protecting the lens.

It is an object of the present invention to solve the above-mentioned drawbacks of the prior art, and to provide a small-sized information communication terminal device having a camera function and an authentication function and also capable of lens protection.

[0009]

In order to solve the above problems, the present invention provides an information communication terminal with an imaging function for imaging a field image formed by an optical lens and transmitting information including image data. In the apparatus, an optical lens feeding mechanism for controlling the optical lens to change the optical lens to a photographing position, an optical filter means for substantially blocking a predetermined wavelength band included in an optical image, and an optical filter means The optical lens feeding mechanism includes an insertion / removal mechanism that performs either movement of the lens on the optical path or withdrawal from the optical path in conjunction with the operation of the optical lens feeding mechanism.

It is characterized by taking a third position and a fourth position in an authentication mode for authenticating a user of this device.

An information communication terminal device with an image pickup function of the present invention is
The protrusions formed on both side plates of the first cover member are inserted into the groove of the housing, and the protrusions are slid along the groove, and the optical lens feeding mechanism and the insertion / insertion mechanism according to the sliding position of the first cover member. By interlocking the removal mechanism, the optical lens is stored at the first position, the main plate covers the optical lens, and the second

Therefore, the lens frame 12a moves in conjunction with the pin 12d that moves along the vertical groove 12f of the fixed frame 12b.
In this embodiment, the pin 12d is inserted into the cam groove 130 and the vertical groove 12f formed on the side surface of the switching cover member 12c described later, and the pin 12d is screwed and fixed to the lens frame 12a. The cam groove 130 is
The amount of sliding in the vertical direction by the pin 12d is restricted. Also,
The vertical groove 12f regulates the amount of sliding along the cam groove 130 by the pin 12d.

The compression coil spring 12e is arranged in the fixed barrel 12b with a size about the lens barrel aperture of the lens frame 12a that does not block the incident light. The compression coil spring 12e biases the lens frame 12a in a protruding direction. The lens barrel 12 is arranged on the filter storage box 14a of the filter insertion / removal mechanism 14.

The switching cover member 12c has a mode switching function for moving the lens barrel 12 along the vertical groove 12f according to each mode to be described later and for selecting the mode according to the moving position. is doing. Switching cover member
The 12c also has a function of regulating the amount of movement of the optical lens that is extended.

The mobile phone 10 operates the camera function according to the selected mode at each of the moving positions of the operation plate 120 serving as the main plate. Modes include digital camera function stop (OFF) 16, daytime (IR ON) 18, macro (M
There are ACRO) 20, night (NIGHT) 22, and certification (IR OFF) 24. The mobile phone 10 is provided with electrode contacts (not shown) on its housing to notify a system controller (not shown) that the mode has been selected by moving the operation plate 120. The switching cover member 12c also has a contact (not shown) indicating the mode selection. The switching cover member 12c is pressed by a user's finger or the like and is further moved to each of the above-mentioned mode positions.
2, 124 are integrally formed. The operation plate 120 may be formed in a size that is easy to operate and takes into consideration the positional relationship of the emission ports of an infrared lamp (not shown).

The space between the side plates 122 and 124 is equal to the filter storage box.
Set to allow 14a. Both the side plates 122 and 124 are integrally provided with a housing (not shown) of the mobile phone 10, and slide the switching cover member 12c according to each mode position.
To operate in this manner, for example, the side plates 122, 124
Form convex portions 126a and 126b at the same height position. Although not shown, concave portions of guide grooves are formed on the housing side at positions corresponding to the convex portions 126a and 126b. Switching cover member 12c
Slides the protrusions 126a and 126b into the guide groove, and
Mounted so that 120 is horizontal. Also, the side plate 1
22 and 124 have guide grooves 128a and 128b formed inside the position lower than the operation plate 120 and not hindering the operation of the lens barrel 12.

A cam groove 130 for restricting the operation of the lens barrel 12 is formed through the side plate 122. The cam groove 130 is
A groove is formed at the lowest level position in the area of the digital camera function stop (OFF) 16. Cam groove at daytime (IR ON) 18
130 forms a level position so as to project into a positional relationship corresponding to a lens used during normal shooting (first position). In the macro (MACRO: IR ON) 20, the cam groove 130 is formed at the highest level position so that the optical lens projects most.
As explained later, daytime (IR ON) 18 and macro (MA
The two modes of CRO: IR ON) 20 correspond to the second position because the infrared cut filter is inserted.

Next, at night (NIGHT: IR OFF) 22, at cam groove 130
Is formed so as to fall to the same level position as during daytime (IR ON) 18 (third position). And authentication (IR OF
In F) 24, the level position is formed at the highest position so as to become the macro (MACRO) 20 again (the fourth position). The reference numerals 16 to 24 representing these positions also represent each mode itself and the positions of the modes.

The pin 12d is threaded. Pin 1
2d is screwed and fixed to a screw hole (not shown) of the lens frame 12a via the cam groove 130 and the vertical groove 12f. Pin 12d is in cam groove 1
30, slide in the vertical groove 12f.

The side plate 122 is a support member 1 for an infrared (IR: Infra-Red) cut filter 142 that is exposed through a through hole 140 formed on the side surface of the filter storage box 14a when it is slid.
A through hole 132 is formed for loosely fitting 44. The side plate 122 regulates the rotation because the end portion 144a of the support member 144 is in contact with the side plate 122 even when the optical filter is rotated about the rotation axis by the tension of the tension spring 146.
The switching cover member 12c is moved so that the support member 14 is inserted into the through hole 132.
When 4 is entered, the above-mentioned rotation restriction is released. Support member 1
Reference numeral 44 rotates to move the infrared cut filter 142 to a position where an effective light beam is cut off. This rotation restriction release state is in the daytime (IR O
In order to function in the N) 18 and macro (MACRO) 20 mode positions, a through hole 132 is provided across both modes.
To form. This positional relationship is shown in FIG.

Returning to FIG. 1, the above-described guide grooves 128a, 128b.
A reflecting plate 134 is inserted in this. The reflector 134 has a lens frame.
A circular opening 134a for inserting the 12a is formed.
Further, the reflecting plate 134 is also formed with an emission port 134b for transmitting a light beam emitted from an infrared lamp (not shown). The reflector 134 is preferably made of an inexpensive material having excellent durability. The reflector 134 may be mirror-coated by vapor deposition. The reflector 134 is provided for the camera to confirm where the image is taken.

Further, in order to perform the above-mentioned confirmation, the reflection plate 13
As shown in FIG. 2, a reflecting surface 134c inclined in a wedge shape may be formed near the opening 134a as shown in FIG. The reflector 134 is
Since only the reflective surface 134c needs to be reflected, a seal coated with a reflective material may be attached to the reflective surface 134c. The distance adjustment is performed by visually recognizing the object scene image from the reflection surface 134c. This is very useful for recognizing the sense of distance between the iris and the camera when shooting the user himself / herself. The exit 134b has a reflective surface 13
It may be provided in 4c. It is desirable to experimentally determine the tilt angle.

Next, the filter insertion / removal mechanism 14 will be described. The filter insertion / removal mechanism 14 includes a filter storage box 14a, an infrared cut filter holding member 14b, a tension spring 146, and a rotating shaft 148. The lens frame is on the filter storage box 14a.
A fixed frame 12b for housing 12a is fixedly arranged. The filter storage box 14a is, for example, partially formed in a U shape, and through holes (not shown) for passing the incident light flux are formed in the top plate 140a and the bottom plate 140b. In the filter storage box 14a, a rotating shaft 148 is vertically installed on the bottom plate 140b inside the box. Further, the storage box 14a includes a top plate 140a and a bottom plate 140a.
Side plate 140c arranged in parallel with the side plate 122 connecting with b
A through hole 140 is formed in the. Further, the side surface plate 140d facing the side surface plate 140c is formed with a locking portion 144e for locking one end side of the tension spring 146. In the locking portion 144e, the infrared cut filter 142 is on the optical path, and the rotation shaft 148 is provided.
The circular frame 14c holding the infrared cut filter 142 and the locking portion 14d for mounting the tension spring 146 are formed so as to be located on a straight line.

As shown in FIG. 3, the through hole 140 is formed to have a width that allows the support member 144 to freely rotate. Since the width of the through-hole 140 is a radius from the rotation shaft 148 of the support member 144 to the tip portion 144a of the support member 144, the width is equal to or larger than a diameter that is twice this radius, and the tip portion is drawn with a circle having this radius. The area where 144a does not contact the side plate 140c of the filter storage box 14a is set. As a result, when the infrared cut filter 142 is placed in the effective light flux range (IR ON), the rotation restriction of the support member 144 is released, and the support member 144 loosely fits in the through holes 140 and 132. In this state, the infrared cut filter 142 is kept on the optical path by the restoring force of the tension spring 146 used in the filter insertion / removal mechanism 14.

Although not described in detail, the infrared cut filter 142 is a filter that cuts off a predetermined infrared wavelength band.

The infrared cut filter holding member 14b includes a circular frame 14c for housing the infrared cut filter 142 and a support member 144. The circular frame 14c is formed with a locking portion 14d for mounting the tension spring 146. The infrared cut filter holding member 14b is inserted into the above-described rotary shaft 148 so that the member 14
A through hole 14e is formed so that b can be loosely fitted. The infrared cut filter holding member 14b includes a side plate 14 and a locking portion 14d of the infrared cut filter holding member 14b via a tension spring 146.
It is connected to the locking portion 144e of 0d. The connection between these components is such that the infrared cut filter 142 enters a predetermined position where it cuts the effective luminous flux in the modes of daytime 18 and macro 20 described later.

In the side plate 140c, the infrared cut filter holding member 14b is formed by inserting the support member 144 into the formed through hole 140.
Are held so as not to fall off the rotating shaft 148. The support member 144 loosely fits in the daytime 18 and macro 20 mode positions. In order to maintain the state in which the tip portion 144a is inserted into the through hole 140 in two modes, the through hole 132 is preferably formed to have a width that does not contact the tip portion 144a in these two modes.

The filter insertion / removal mechanism 14 includes a switching cover member 12
When c is slid in accordance with the arrow A, the tip end portion 144a of the infrared cut filter holding member 14b rotates to retract from the above-mentioned predetermined position for cutting the effective light flux. Infrared cut filter 142
Is the case of mode positions 16, 22 and 24.

FIG. 4 shows an off state in which the infrared cut filter 142 in the filter insertion / removal mechanism 14 is retracted. The filter storage box 14a is fixed to the switching cover member 12c. When the switching cover member 12c is slid in the direction of arrow A, the tip portion 144a of the infrared cut filter holding member 14b comes into contact with the opening end 132a of the through hole 132. As a result, the infrared cut filter holding member 14b is moved around the rotation shaft 148 by the arrow B.
Rotate in the direction. When it is further slid in the direction of arrow A, it rides on the side plate 122. At this time, the tension spring 146
The restoring force tries to rotate the infrared cut filter holding member 14b in the direction opposite to the arrow B. However, rotation of the infrared cut filter holding member 14b is restricted by the tip portion 144a contacting the side surface plate 122. The infrared cut filter holding member 14b retracts and stops from the position on the optical path of the infrared cut filter 142 indicated by the broken line circle 142a due to the rotation restriction.

Further, in the mode in which the infrared cut filter 142 is not inserted, that is, in modes 22 and 24, the infrared filter 142 needs to be retracted. In this case, the operation plate 120 is slid in the direction of arrow a as shown in FIG. As a result, the switching cover member 12c moves integrally. The tip portion 144a of the infrared cut filter holding member 14b comes into contact with the opening end 132b of the through hole 132 formed in the side surface plate 122. As a result, the infrared cut filter holding member 14b rotates in the arrow C direction about the rotation shaft 148. When it is further slid in the direction of arrow a, it rides on the side plate 122. At this time, tension spring 1
46 tries to rotate the infrared cut filter holding member 14b in the direction opposite to the arrow C by the restoring force. However,
Rotation of the infrared cut filter holding member 14b is restricted by the tip portion 144a contacting the side surface plate 122. The infrared cut filter holding member 14b retracts and stops from the position on the optical path of the infrared cut filter 142 indicated by the broken line circle 142a due to the rotation restriction.

As described above, the filter insertion / removal function 14 supports the infrared cut filter holding member 14b and allows the infrared cut filter 142 to be inserted only in a desired mode.
The insertion state is maintained by the tension spring 146 while being loosely fitted in and rotated about the rotation shaft 148. In addition, the infrared cut filter 142 is pulled out (retracted) in response to sliding in a mode other than this, and the rotation by the tension spring 146 causes the tip portion 144a of the infrared cut filter holding member 14b and the side plate 122 to penetrate. After the contact with the mouth 132, the rotation is restricted by the contact with the side plate 122, and this rotation restricted state is maintained. The through-hole 132 may be formed according to the rotation restriction position. By using this mechanism, the support member 144 can be stored with a short length.

By the way, on the operation plate 120, there is formed a contact (not shown) for mode switching connection on the casing body side of the portable telephone 10 corresponding to the position of the triangular mark 120a.
In response to this sliding connection, the mobile phone 10 decodes the supplied mode instruction signal and supplies which mode is selected to the system control unit (not shown) as mode selection information. Although not shown, the filter storage box 14a
At the subsequent stage, solid-state image pickup devices are arranged in a two-dimensional array that converts an incident light beam into an electric signal. A mechanical shutter may be arranged on the incident light side of the solid-state image pickup device if there is a margin in the arrangement space of the components.

Next, the lens barrel 12 and the filter insertion / removal mechanism
The operation state in each mode of the mode compatible camera 100 in which 14 is assembled will be described. 6 mode compatible camera 100 of FIG.
Indicates that the function of the digital camera is off. The lens frame 12a is housed in the fixed frame 12b when the pin 12d is fixed to the lowest position of the cam groove 130. At this time, the lens frame 12a is fixed to a position lower than the operation plate 120 and not in contact with the operation plate 120. And the operation plate 120
Can cover the optical lens system including the lens frame 12a and prevent scratches, breakage, or the like that may occur when not in use.

Although not shown, the tip portion 144a of the support member 144 of the infrared cut filter 142 in the filter insertion / removal mechanism 14 is restricted in rotation by contacting the side surface plate 122 in the extension direction of the cam groove 130. . In this rotation restricted state, the infrared cut filter 142 is out of the effective light flux of the optical lens system held by the lens frame 12a. With this configuration, when the function of the digital camera is turned off, the switching cover member 12c uses a stroke 136 for performing the subsequent mode setting. An area for this stroke 136 minutes is secured in advance. A circular opening 134a is formed in the reflecting plate 134 immediately above the lens frame 12a.

Next, FIG. 7 shows a state in which the operation plate 120 is slid in the direction of arrow D. Mode 18 is a daytime mode. This sliding moves the pin 12d to a middle height of the cam groove 130. In response to this, the lens frame 12a is pushed up in the protruding direction along the vertical groove 12f in the fixed frame 12b. The lens frame 12a projects through the opening 134a. The lens frame 12a has the optical lens arranged at a setting position where normal shooting is performed. The support member 144 loosely fits the through hole 132 of the side plate 122 as shown by the tip portion 144a of the support member 144. Although not shown, the tension springs 146 have a relationship in which the tension is minimized. As a result, in mode 18, the infrared filter 142 is placed in such a positional relationship that it enters the cross-sectional area of the effective light beam that passes through the optical lens. That is, the use of the infrared cut filter is on. By using the mode-compatible camera in this state, the mobile phone 10 can perform shooting even in the daytime.

Next, FIG. 8 shows the state of the mode 20 in the macro mode. This state is the operation plate 120 of the switching cover member 12c.
Is further slid from the state of FIG. 7 in the direction of arrow D. By this sliding, the pin 12d moves upward along the cam groove 130 and moves to a position higher than that in the daytime mode 18. As shown in FIG. 7, the cam groove 130 moves to the highest position on the side plate 122. In response to the sliding to this height, the pin 12d moves along a vertical groove 12f (not shown) to push up the lens frame 12a. As a result, the lens frame 12a is projected to the outermost side through the emission port 134a of the reflection plate 134.

In the macro photography, it is desired that the incident light in the infrared region be cut off to be photographed as in the daytime photography. Therefore, the infrared cut filter 142 continues to be in the use-on state. This continuation can be obtained if the support member 144 in the through hole 132 is loosely fitted and the state where the rotation restriction of the side surface plate 122 and the tip portion 144a is released is maintained. Therefore,
It is understood that the through-hole 132 may be formed with a length corresponding to the sliding amount of the two modes. These modes correspond to the second position.

Next, the state of mode 22 in the night mode is shown in FIG.
Shown in. This state is obtained by further sliding the operation plate 120 of the switching cover member 12c from the state shown in FIG. 8 in the direction of arrow D. By this sliding, the pin 12d moves downward along the cam groove 130 and moves to the same height as in the daytime mode 18.
This sliding moves the pin 12d downward along the not-shown vertical groove 12f. As a result, the lens frame 12a has the same protrusion amount as in the daytime, and the shooting distance of the single focus lens is set.

In this night mode 22, the infrared cut filter
142 is unnecessary. Infrared cut filter that responds to sliding 1
The rotation of the support member 144 of 42 is restricted so that the support member 144 is out of the effective light flux range. Then, the restoring force of the tension spring 146 in the filter insertion / removal mechanism 14 tries to return the infrared cut filter 142 into the effective light beam, but the tip portion 144a of the support member 144 abuts the side surface plate 140c to regulate the rotation. I am maintaining.

Finally, the state of the authentication mode of mode 24 is shown.
Shown in 10. The operation plate 120 is further slid in the direction of arrow D to the position for selecting the authentication mode. By this sliding, the lens frame 12a is again moved to the position where it is most projected. By this movement, the pin 12d moves to the rightmost side of the through hole 130.
The authentication mode 24 has the same feeding amount as the macro mode 20. This authentication is performed by photographing the iris with infrared rays. Therefore, in the authentication mode, the infrared cut filter is arranged at a position outside the effective light flux. With this arrangement, it is preferable that the rotation restriction state of the night mode 22 is continued.

When photographing the iris in the authentication mode 24, the user projects the surrounding object scene to be photographed on the reflecting plate 134 between the lens frame 12a and the operation plate 120. The user confirms the position of the mobile phone 10 and adjusts the target so that the optical lens can be caught. After this adjustment, the user releases the shutter and shoots. At this photographing timing, an infrared lamp (not shown) emits light and infrared rays are emitted from the emission port. Light from the object field passes through each of the optical lenses and enters the solid-state image sensor.

Further, the mobile phone 10 has a mode compatible camera.
The 100 is mounted and the selection operation of each mode and the state of the lens frame 12a are briefly shown (see FIGS. 11 to 15). Figure 11 mobile phone
At 10, the mark 120a on the operation plate 120 is set to the display OFF position. In order to perform this alignment, the switching cover member 12c
Uses an arrangement space for 136 strokes to be moved. When the mode 16 in the off state is released, the mode compatible camera 100 is activated.

In FIG. 12, the mark 120a on the operation plate 120 is aligned with the figure 200 in which the sun and clouds representing the daytime mode 18 are drawn. The lens frame 12a is projected so as to have a shooting distance for shooting a normal landscape or the like. Insert an infrared cut filter so as to cut the effective luminous flux. The state of this insertion is called IR ON. In FIG. 13, the mark 120a on the operation plate 120 is aligned with the tulip figure 202 representing the macro (close-up) mode. In response to this, the lens frame 12a further projects. Even in this mode 20, the infrared cut filter is set to IR ON.

In FIG. 14, the mark 120a on the operation plate 120 is aligned with the figure 204 showing the building and the crescent moon representing the night mode. The projection of the lens frame 12a is settled down from the position of the macro mode to the shooting distance in normal shooting. At this time, the infrared cut filter is not inserted so that it also passes infrared light, and is turned off (IR OFF).

Finally, in FIG. 15, the mark 120 on the operation plate 120 is
Align a with the OK mark figure 206 representing the authentication mode 24.
The graphic 206 uses an OK mark indicating confirmation and consent since it asks whether or not confirmation is possible. The lens frame 12a has the same protrusion amount as in the macro mode. The user adjusts the arrangement of the mobile phone 10 so that the pupil is on the optical lens from the image reflected on the reflection plate 134. After the adjustment, the infrared lamp is caused to emit light and the target (eye of the target) is irradiated with the light from the emission port 134a.
Upon receiving this irradiation, the optical image incident from the target is formed on the solid-state image sensor by a plurality of optical lenses.

An image pickup signal obtained by photoelectric conversion by the solid-state image pickup device is used as image data. The mobile phone 10 further compares the iris data registered in advance by using the image data (iris data), and determines whether the user operating the mobile phone 10 is a registrant.
