Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image stabilization camera in which an image stabilization optical system is shifted in a direction different from the optical axis direction to prevent image blur caused by camera vibration.

[0002]

2. Description of the Related Art A camera shake sensor (for example, an angular acceleration sensor) for detecting the amount of camera shake caused by camera shake, etc., and a camera shake correction optical system constituting a photographing lens as an optical axis based on the detection output of the camera shake sensor. There is known a camera shake correction camera that includes an anti-vibration drive mechanism that is electrically driven in a direction orthogonal to each other, and that prevents the shake of a captured image due to camera shake by operating the anti-vibration drive mechanism.

On the other hand, a camera having a red-eye reduction function is conventionally known. In this type of camera, for example, light emission (pre-light emission) of a red-eye reduction lamp is started in response to a full-press operation of a release button, and after that, a flash photographing by an electronic flash device is performed after waiting for a predetermined time. According to this
Since flash photography is performed in a state where the pupil of the subject (person) who has observed the pre-emission is closed, the red eye is not noticeable on the photographed picture.

[0004]

By the way, in the image stabilization drive mechanism in the above-described camera shake correction camera, normally, the camera shake correction optical system is first moved to a predetermined initial position (for example, the camera shake correction optical system when the shutter release button is fully pressed). The optical axis of (1) coincides with the optical axis of the photographing lens), and from that position to a position corresponding to the output of the camera shake sensor.
Therefore, after the full-press operation, it is necessary to delay the photographing by at least the time for driving the image stabilization optical system to the initial position. On the other hand, it is generally 0.7 to 1 from when the person to be photographed sees the pre-light emission for red-eye reduction until the pupil diameter becomes the minimum.
It takes about a second, and if no light enters the pupil after that, the pupil diameter gradually increases. Therefore, in order to obtain a satisfactory red-eye reduction effect, it is necessary to wait for 0.7 to 1 second from pre-flashing to flash photography. In addition, in the type of camera that performs focusing by moving the focusing optical system of the photographing lens from the reset position (retracted position) by a predetermined amount in accordance with the full-press operation of the release button,
The shorter the shooting distance, the larger the amount of extension of the focusing optical system, and the longer the time until focusing.

As can be seen from the above, both the camera shake correction function and the red-eye reduction function include elements that lengthen the time from the full-press operation to the photographing. Therefore, if the image stabilization camera has a red-eye reduction function, unless the timing of the pre-light emission, focusing and operation of the anti-vibration drive mechanism is devised when the flash shooting condition is satisfied, especially when the shooting distance is short (focusing optical When the amount of extension of the system is large), the start of shooting may be significantly delayed, and it may not be possible to take advantage of the shutter chance at a break. Further, when pre-light emission for red-eye reduction is performed by a lamp different from the electronic flash device, the light emission energy is smaller than that in the case of using the electronic flash device, and thus it is necessary to lengthen the light emission time. Will be more serious.

An object of the present invention is to pre-light emission for red-eye reduction,
By devising the order of focusing lens movement and the operation of the anti-vibration drive mechanism, the time from the output of the shooting start signal to the flash shooting is minimized and the satisfactory image stabilization and red-eye reduction effects are achieved. An object is to provide a camera shake correction camera that can be obtained.

[0007]

SUMMARY OF THE INVENTION The present invention provides a camera shake detecting means for detecting a camera shake amount due to a camera shake and the like, and a camera shake correction based on a detection output of the camera shake detecting means for preventing a shake of a photographed image. The present invention is applied to a camera shake correction camera provided with an image stabilization drive unit that performs a camera shake correction operation for driving an optical system in a direction different from the optical axis. Then, focusing means for driving the taking lens to a predetermined focus position based on the result of distance measurement by the distance measuring means, flash photographing means for causing the electronic flash device to emit main light to perform flash photographing, and for reducing the red-eye effect In addition, pre-flashing means for performing pre-flashing prior to flash photography, and when the flash shooting conditions are met, the camera shake detection means starts camera shake detection in response to the output of the shooting preparation signal, and the shooting start signal is output after the shooting preparation signal is output. Is output, the focusing means is operated, the pre-light emitting means is operated after the focusing means has finished operating, and then the image stabilization drive system is driven to a predetermined initial position by a predetermined waiting time. And a control means for starting the camera shake correction operation by the anti-vibration driving means and activating the flash photographing means after the time has elapsed. To resolve the point.

[0008]

When the flash photographing condition is satisfied, the shake detection means starts the shake detection in response to the output of the shooting preparation signal, and when the shooting start signal is output after the shooting preparation signal is output, the focusing means performs the focusing. After the focusing operation is completed, the pre-light emission means performs pre-light emission for red-eye reduction, and then the image stabilizing drive means drives the camera shake correction optical system to a predetermined initial position. afterwards,
After the lapse of a predetermined waiting time, the camera shake correction operation by the image stabilization drive means is started and the flash photography by the flash photography means is performed. In this case, the sum of the initial position drive time of the image stabilization optical system and the standby time corresponds to the red-eye reduction standby time, and the initial position drive of the image stabilization optical system is performed during this red-eye reduction standby time. The reduced waiting time can be used effectively.

3 and 4 are flow charts showing the procedure of photographing control by the CPU 41. When the program starts from step S1, it waits until the half-press switch SW1 is turned on in step S2, and when it is turned on, in step S3, the camera shake detection by the camera shake sensor 48 is started, and the image shake is detected based on the detection result. The shift amount of the correction lens 3 for preventing the above is calculated (camera shake calculation is performed). In step S4, the photometric circuit 46
Is operated to input the subject brightness which is the detection output thereof (performs photometric processing). In step S5, the distance measuring circuit 47 is operated and the object distance which is the detection output thereof is input (distance measuring processing is performed).

In step S6, the sensitivity detection circuit 53 is operated, and the film ISO sensitivity as the detection result is input. In step S7, the input subject brightness,
A well-known AE calculation is performed based on the ISO sensitivity to obtain an exposure value for obtaining an appropriate exposure, and it is determined whether or not the electronic flash device 56 emits light and whether or not pre-flashing occurs, and the electronic flash device 56 is caused to emit light. If the condition is met, the SB emission mode is set. In step S8, FM (flashmatic) calculation is performed based on the input subject distance, ISO sensitivity, and guide number of the electronic flash device 56 to obtain the aperture value at the time of flash photography. In step S9, the output of the zoom motor rotation amount detection circuit 52 is read to recognize the current focal length of the taking lens.

In step S10, it is determined whether or not the SB light emission mode is set. If it is not set, the process proceeds to step S12, and if it is set, step S11.
Proceed to. In step S11, it is determined whether or not the charging of the electronic flash device is completed. If not completed, the process is terminated, and if completed, the process proceeds to step S12.

In step S12, the camera waits for a waiting time required for the output of the camera shake sensor 48 to stabilize. In step S13, it is determined whether or not the amount of camera shake detected by the camera shake sensor 48 is equal to or greater than a predetermined amount. If the amount of camera shake is greater than or equal to the predetermined amount, a display element (not shown) for notifying camera shake is turned on in step S14, and the predetermined amount is determined. If less, the display element is turned off in step S15. Then, in step S16, it is determined whether the release switch SW2 is on or off. If it is off, in step S17 the halfway press switch SW1 is turned on or off.
Determine off. If the half-push switch SW1 is off, the process is terminated, and if it is on, the process returns to step S13.

In step S16, the release switch SW2
4 is turned on, the display element for camera shake notification is turned off in step S18 of FIG. 4, and then in step S19, the lens drive amount for focusing is calculated based on the subject distance. In step S20, the focusing lens 4 is moved by the calculated lens driving amount.
The focusing motor M2 is driven through the focusing motor driver 49 to drive the focusing motor M2. The lens holder 11 is rotated by the rotation of the motor M2 through the gears 18 and 11a.
Rotates, and along with this, the helicoids 10b, 11b
By this action, the lens holder 11 is driven in the optical axis direction. That is, the focusing lens 4 rotates and moves in the optical axis direction to perform focusing. The photo interrupter 20 detects information about the moving amount of the focusing lens 4 and inputs it to the CPU 41 via the focusing lens moving amount detection circuit 50.

In step S21, it is determined whether or not pre-light emission for red-eye reduction is performed. If pre-flashing is to be performed, the process proceeds to step S22, and pre-flashing of the red-eye reducing lamp 58 is started via the lamp drive circuit 57. Step S2
In 3, the timer for measuring the red-eye reduction standby time is started, and in step S24, the centering circuit 54 is operated to move the correction lens 3 to the center position (the position where the optical axis of the lens 3 coincides with the optical axis of the taking lens). Drive to. In step S241, it waits until 0.7 seconds elapse from the timer start, and then in step S242, pre-emission is stopped and the process proceeds to step S27.

On the other hand, if the pre-light emission is not performed, the process proceeds from step S21 to step S25, and the correction lens 3 is driven to the center position in the same manner as described above. After waiting for a predetermined waiting time in step S26, the process proceeds to step S27 to start the camera shake correction operation. That is, the Y-direction motor M of FIG.
3, the X-direction motor M4 is driven to shift the correction lens 3 in the direction orthogonal to the optical axis by the shift amount obtained by the camera shake calculation. In step S28, the correction lens 3
After waiting for a predetermined time until the moving speed of (1) is stabilized, the aperture / shutter 12 is opened / closed via the aperture / shutter motor driver 43 in step S29. If the SB light emission mode is determined, the electronic flash device 56 performs main light emission in synchronization with the driving of the shutter 12.

Then, in step S30, the Y-direction motor M3 and the X-direction motor M4 are stopped to end the camera shake correction operation, and then in step S31, the camera shake detection by the camera shake sensor 48 is ended. In step S32, the correction lens 3 is driven to a predetermined reset position, and step S3
In step 3, the focusing lens 4 is returned to the reset position, and in step S34, the film is wound by one frame via the film winding circuit 55, and then the process is ended.

The camera operation based on the procedure of FIGS. 3 and 4 will be described with reference to FIG. FIG. 5 is a diagram showing the timing of each camera operation performed during flash photography and the temporal change in the diameter of the pupil of the subject. When the release button is pressed halfway (when a shooting preparation signal is output) when the flash shooting condition is satisfied, in response thereto, the shake detection by the shake sensor 48 is started. After that, when the release button is fully pressed at time T1 (when a shooting start signal is output),
Focusing is performed, and pre-light emission for red-eye reduction by the lamp 58 is started at time T2 after the end of focusing. From time T21 after the start of pre-emission, the pupil of the subject begins to gradually contract, and after the pre-emission for 1 second is completed, the pupil continues to contract.

When the pre-light emission is completed, driving of the image stabilizing lens 3 to the center position (initial position) is started at time T3, and after the completion of driving, a predetermined waiting time is waited. After that, the camera shake correction operation is started at time T4, and then at time T5.
At this time, the shutter is opened, the electronic flash device 56 actually emits light at time T6, and the shutter is closed at time T7. After that, the focusing lens is returned to the reset position from time 7 to time 8, and one frame of film is wound from time T8 to time T9.

According to the above operation, after the completion of the pre-light emission,
Flash photography is performed after the total time of the time required to drive the initial position of the image stabilizing lens 3 and the waiting time has elapsed. This total time corresponds to the red-eye reduction standby time, and by delaying the shooting by this time, flash photography is performed with the pupil diameter of the subject being the minimum as shown in the figure, so the red-eye reduction effect should be maximized. You can Further, in the present embodiment, since the initial position drive of the image stabilizing lens 3 is performed during the red eye reduction standby time, the red eye reduction standby time can be effectively utilized, and the initial position drive is performed other than the red eye reduction standby time. It is possible to shorten the time from the full-pressing operation of the release button to the flash photographing as compared with the case of performing.

When the photographer presses the release button fully, camera shake normally occurs due to the pressing force. If the camera shake amount at that time is large, even if the camera shake correction operation is performed. Image blur may not be prevented. However, as in the present embodiment, in the flash photography after waiting for the red-eye reduction standby time from the pre-emission, the camera shake due to the full-press operation can be attenuated during the red-eye reduction standby time, and the attenuation Shooting can be performed in this state. In other words, in the present embodiment, the red-eye reduction standby time can also be used as the camera shake attenuation standby time, which makes it possible to obtain a satisfactory camera shake correction effect during flash photography.

In the configuration of the above embodiment, the camera shake sensor 48 is the camera shake detection means, the X-direction and Y-direction drive mechanisms 100x and 100y are the image stabilization drive means, and the distance measuring circuit 47.
Is a focusing motor M2 and CPU
Reference numeral 41 constitutes a focusing means, lamp 58 constitutes a pre-light emitting means, and CPU 41 constitutes a flash photographing means and a control means.

The structure of the image stabilizing device is not limited to that shown in FIG. 2, and the position of the image stabilizing lens 3 is not limited to that of the embodiment. Further, the lamp 58 serves as a pre-light emitting means.
However, the electronic flash device may also be used.

[0036]

According to the present invention, the initial position of the image stabilizing optical system is driven during the red-eye reduction waiting time after the pre-flash, so that the red-eye reduction waiting time can be effectively used, and the red-eye reduction waiting time can be effectively used. It is possible to minimize the time from the output of the shooting start signal to the flash shooting without sacrificing the reduction effect. Further, since the red-eye reduction waiting time can be used also as the camera shake attenuation waiting time, a satisfactory camera shake correction effect can be obtained at the time of flash photography.
