Field of the Invention The present invention relates to a camera equipped with an autofocus function and capable of flash photography with a strobe (electronic flash device), and in particular, an AF auxiliary light source for enhancing the autofocus function and a red-eye phenomenon upon strobe emission. And a light source for red-eye reduction having a red-eye reduction function for reducing

[0002]

2. Description of the Related Art In a camera having an autofocus function, in order to enable the autofocus function in a dark place, for example, an LED or a lamp as an AF auxiliary light source (hereinafter referred to as AF auxiliary light lamp) during the autofocus operation. It has been known that a subject is illuminated by emitting auxiliary light (hereinafter referred to as AF auxiliary light).

Further, in a camera capable of flash photography by a strobe, the strobe is built in the camera body,
There is also known a structure in which a red-eye phenomenon that occurs during flash photography is reduced by creating a so-called pop-up state that is used by causing the strobe to move away from the shooting optical axis during flash photography. In such a flash-capable camera, the subject's pupil is shrunk by pre-flashing immediately before the strobe is fired or by irradiating a lamp with a red-eye reduction lamp (hereinafter referred to as a red-eye reduction lamp). Those adopting such a structure are also known.

Further, in a camera having an autofocus function and capable of flash photography by a strobe, the AF auxiliary light lamp and the red-eye reduction lamp described above are commonly used to reduce the cost and the space for incorporating the camera. There is also known a light source that functions as a light source, that is, a single lamp and a single optical system.

[0005]

In the camera as described above, the following points become a problem when the AF auxiliary light lamp and the red-eye reduction lamp are used as a common light source for autofocus. That is, the red-eye reduction light from the red-eye reduction lamp must have an optical system with a wide irradiation angle in order to irradiate the entire area within the shooting screen, whereas the AF auxiliary light is used during autofocus. Since it suffices to irradiate only the detection area, it has the contradictory property that it is necessary to have an optical system that irradiates a far distance with a narrow irradiation angle. Therefore, it is difficult to configure such red-eye reduction light and AF auxiliary light using one common lamp and one optical system.

When the optical system is designed with the irradiation angle required for the red-eye reduction function in using the lamp and the optical system in such a camera, the light cannot reach a distant object at the time of autofocus, while If the optical system is designed with the irradiation angle required for the focus function, there is a problem that the red-eye reduction effect cannot be exerted on a subject outside the autofocus detection area.

The present invention has been made in view of the above circumstances, and is a camera that uses both AF auxiliary light and red-eye reduction light in one lamp and one optical system, and as described above. It is an object of the present invention to obtain a camera that can realize a wide irradiation angle for contradictory red-eye reduction light and a narrow irradiation angle for AF auxiliary light with a single lamp at low cost.

In addition, these optical systems can be switched by independently using one of these optical systems or combining them with the other.

Further, in the camera according to the present invention, the movable portion is irradiated with light from one illumination light source to the photographing screen at an arbitrary irradiation angle, for example, the entire photographing screen with a wide irradiation angle for red eye reduction. The first optical system provided and the light source for illumination are provided on the non-movable part so that the photographing screen is illuminated with an irradiation angle different from that of the first optical system, for example, only a detection area at the time of autofocusing with a narrow irradiation angle. A second optical system is provided, and by operating the movable part such that one of these two optical systems is used independently or combined with the other, these optical systems are selectively switched and illumination is performed. The irradiation angle of the light from the light source is changed.

Further, the camera according to the present invention is provided with an operating mechanism capable of deviating the irradiation optical axis of the stroboscopic light emitting section from the optical axis of the photographing lens in order to obtain the red-eye reducing function, and also has an autofocus function section and a red-eye function section. It has one illumination light source provided to obtain the illumination light in the mitigation function section, and two or more optical systems that illuminate light from the illumination light source on the shooting screen at different illumination angles. The first mechanism provided in the operating mechanism so as to obtain the red-eye reduction function by irradiating the entire screen with the optical system at a wide irradiation angle.
And the second optical system provided in the non-movable part of the camera body so as to have an autofocus function by irradiating the photographic screen with the illumination light source at an irradiation angle narrower than that of the first optical system. The first and second optical systems are switched by selectively combining them by the operation of the movable function, and the irradiation angle of the light from the illumination light source is changed.

[0011]

According to the present invention, by switching and using the optical systems that illuminate with different irradiation angles, it is possible to illuminate light from one illuminating light source into a detection area for autofocus at a narrow irradiation angle, The entire shooting screen can be illuminated with a wide irradiation angle to reduce red eye.

In particular, according to the present invention, the first optical system is selectively operated by the movable part, and when the first optical system is used independently, the light from the illumination light source is used to reduce the red-eye reduction in the entire photographing screen. With a wide irradiation angle,
The optical system of is operated by the movable part, and the second part is provided on the non-movable part.
It is possible to irradiate only the detection area at the time of autofocusing on the photographing screen with a narrow irradiation angle by combining with the optical system.

Further, according to the present invention, the non-movable portion is provided with the stroboscopic light emitting portion whose irradiation angle is deviated from the optical axis of the photographing lens by the operating mechanism, and which illuminates only the detection area at the time of autofocus with a narrow irradiation angle. The first side on the operating mechanism side that illuminates the entire photographing screen with a wide irradiation angle in conjunction with the AF auxiliary light of the autofocus function section by the second optical system on the side and the flash illumination of the strobe light emitting section.
If an illumination light source that obtains the red-eye reduction light of the red-eye reduction function section of this optical system is provided, the light from this illumination light source is automatically focused using the first and second optical systems during auto-focusing. When the red-eye is reduced, only the first optical system operated by the actuating mechanism together with the stroboscopic light emitting unit is used to illuminate only the detection area at the time with a wide irradiation angle. Can be irradiated.

As a result, during autofocus, the first and second optical systems are used to irradiate only the autofocus detection area with light, and during red-eye reduction, only the first optical system that operates in conjunction with the strobe light emitting section is used. It is possible to irradiate light to all the areas within the shooting screen by using it.

In the popped down state as shown in FIG. 1, the AF auxiliary light through the AF auxiliary light irradiation lens 19 is applied to a part of the photographing screen with a narrow irradiation angle.

In the camera having the above-described embodiment structure, focusing by autofocus and AF when necessary are performed.
A shooting operation including the use of auxiliary light, strobe light emission, and red-eye reduction lamp light emission is performed as shown in FIG. That is, in the pop-down state shown in FIG. 1, the release button 1a is half-pressed as shown in step (hereinafter referred to as "S") 101, and the first stroke of the release switch (half-press switch on). The camera starts the shooting operation.

First, in step S102, the brightness of the subject, which is the object of distance measurement, is measured. Then, it is determined in S103 whether the measured value of the subject brightness is equal to or higher than a predetermined value. If the measured value is equal to or higher than the predetermined value, the process proceeds to S104, and the sensor output of the autofocus sensor 10 is taken into the control device 11. That is, the autofocus sensor 10 sends an output signal corresponding to the pattern of the subject image received through the taking lens to the control device 11. Here, the control device 11 determines the brightness of the subject based on the level of the received signal, and if the brightness is equal to or higher than a predetermined level, based on the output signal, S
104 or S105 is selected.

That is, if the measured value is less than the predetermined value, S
In step 105, the control device 11 operates the lamp drive circuit 18 to turn on the lamp 17, and starts irradiation of the AF auxiliary light to the focusing area. At this time, the stroboscopic light emitting section 14 is in the pop-down state shown in FIG. 1, and the lamp 18 emits light, and the AF is passed through the lenses 16 and 19.
The auxiliary light is emitted.

Next, in S106, the output signal from the sensor 10 is acquired by the control device 11, the lamp 17 is extinguished in S107, and the irradiation of the AF auxiliary light is stopped. Then, in S108, the control device 11 controls the focusing lens 4 according to the output signal from the sensor 10 described above.
The drive amount calculation processing of is performed. If "yes" is selected in S103, the process proceeds to S108 via S104.

Then, the focusing lens 4 is moved back and forth in the required direction on the optical axis through the autofocus actuator 12 by the control device 11 to perform focusing. In S109, it is determined whether or not the in-focus state is obtained by this focusing. If "no", the control device 11 continues to drive the lens in S110, returns to S103, and returns to the in-focus state. The state detection, the lens drive amount calculation, and the lens drive are repeated until the output signal of the sensor 10 indicates the focused state.

When it is determined in S109 that the lens 4 has moved to the in-focus position, the process proceeds to S111, in which it is determined whether or not the release button 1a has been fully pressed. Then, when the release switch is fully pressed, the pop-up operation of the flash light emitting unit 14 is performed via the pop-up actuator 15 in S112. Next, in S113, the lamp 17 is turned on, and the light is emitted through the red-eye reduction light emitting lens 16 as red-eye reduction light toward the entire photographing screen at a wide irradiation angle.

Then, in S114, known film exposure operations such as photometry, flashing in the strobe light emitting section 14, mirror up, and shutter driving are performed. Next, in S115, the pop-up actuator 15 performs the pop-down operation of the strobe light emitting unit 14, the film is wound in S116, and the other shooting operation mechanism units are returned to the charge position. This routine ends when shooting is possible.

In particular, according to the present invention, it is effective for the case where the brightness of the object is low and the AF auxiliary light and the flash light emission by the stroboscopic light emitting section 14 are required and the red-eye reduction function is selected. .

In the above description, the flash emission unit 14 is popped up by the release full-press operation, but it may be popped up when the focusing operation by autofocus is completed.

According to the present invention as described above, a camera having an autofocus function and a strobe function is provided.
A built-in strobe light emitting unit 14 that can be popped up and down is provided with a lamp 17 as a light source for illumination and a lens 16 for red-eye reduction light irradiation that emits light from the lamp 17 at a wide irradiation angle of the entire photographing screen. ing. In addition, the lamp 1 is attached to the non-movable part (fixed part) of the camera body 1.
An AF auxiliary light irradiation lens 19 for irradiating the light of No. 7 with only the detection area of the autofocus in the photographing screen is provided.

Therefore, for example, when performing flash photography using the strobe light emitting portion 14 in a dark place, the strobe light emitting portion 14 is in a pop-down state during autofocus, and the red-eye reducing light irradiation lens 16 is used.
Only the range-finding area is illuminated by the lens 19 for illuminating the AF auxiliary light via the, and a desired autofocus function can be exhibited. Immediately before the exposure operation, the strobe light emitting section 14 is popped up to illuminate the entire photographing screen only with the red-eye reduction light irradiating lens 16, and then the strobe light emitting section 14 is caused to emit light so that the film can be exposed together with the flash light.

Here, the narrow irradiation angle by the above-mentioned AF auxiliary light irradiation lens 19 may be set as follows. For example, when the lens barrel 2 having a photographing lens system of 24 mm is attached to the camera body 1, the irradiation angle required for the AF auxiliary light is about 16 ° and 50 mm.
When the lens barrel 2 of 1 is attached, about 8 ° is required. Therefore, for example, when the irradiation angle of the AF auxiliary light is fixed, it may be set to about 16 to 20 °.

It is needless to say that the present invention is not limited to the structure of the embodiment described above, and the shape, structure, etc. of each part of the camera capable of flash photography by the stroboscopic light emitting section 14 can be appropriately modified or changed. For example, in the above-described embodiment, a case has been described in which light from one illumination light source (lamp 17) is transmitted through the two optical systems 16 and 19 alone or in combination to perform illumination with different irradiation angles. However, you may employ | adopt the structure which selects each optical system and exchanges and uses it.

Further, according to the present invention, in the above-described embodiment, the case where the red-eye reduction light irradiation lens 16 is provided on the movable side and the AF auxiliary light irradiation lens 19 is provided on the non-movable side is exemplified. However, the configuration may be reversed. further,
Of course, the present invention is not limited to the single-lens reflex camera as described above. Further, when a zoom lens is used as the photographing lens system, a configuration may be adopted in which the respective lenses 16 and 19 are operated in a zooming manner.
