Field of the Invention The present invention relates to an image pickup apparatus, a control method for the image pickup apparatus, and a medium for supplying a computer with a program describing the control method. The present invention relates to an imaging device that records by a film or an imaging element, a control method applied to the imaging device, and a medium that supplies a computer with a program describing the control method.

2. Description of the Related Art Conventionally, as a stereoscopic video image capturing method, there has been a method of using a stereo adapter which can be attached to a general monocular camera to obtain a plurality of images having different viewpoints, instead of using a dedicated compound eye camera. Was.

FIG. 6 is a diagram showing the principle configuration of a stereo adapter, and FIG. 7 is a diagram showing an image taken by a monocular camera equipped with the stereo adapter.

In FIG. 6, reference numeral 101 denotes a cubic object,
Reference numeral 102 denotes a camera body, and 103, a photographing lens. 104 is a first reflecting surface L, 105 is a first reflecting surface R, 106
Is a second reflecting surface L, 107 is a second reflecting surface R, and the first reflecting surface L104, the first reflecting surface R105, the second reflecting surface L106, and the second reflecting surface R107 constitute a stereo adapter.

[0005] The light beams L and R that exit the subject 101 and pass through different areas are first reflected by the first reflecting surface L, respectively.
104, reflected by the first reflecting surface R105, further reflected by the second reflecting surface L106, and the second reflecting surface R107, and incident on the taking lens 103 of the camera body 102;
8 is formed. Therefore, as shown in FIG.
Are divided into two equal parts in the horizontal direction, and a subject image is formed by the light flux L and the light flux R, respectively. In addition, the viewpoints of the subject images formed in the regions 109 and 110 are apparently at positions indicated by l and r in FIG. 6, respectively, and have parallax. The image formed on the image plane 108 is recorded as one image or image file.

[0006] Then, by a three-dimensional reproducing device (not shown),
Of the images recorded as one image by the camera body 102, an image formed in the area 109 is displayed so as to be viewed only by the left eye of the observer, and an image formed in the area 110 is displayed only by the right eye of the observer. Thus, the stereoscopic image can be observed by an observer.

[0007]

However, the camera body 102 to which the stereo adapter is mounted has the following problems since it is not considered in advance that the stereo adapter is mounted.

(1) Automatic exposure adjustment A on camera body 102
When the function of E or auto focus adjustment AF is added, such adjustment is performed based on the image near the center of the captured image, but the center of each image captured when the stereo adapter is attached is captured when the stereo adapter is not attached. Therefore, the automatic exposure adjustment AE and the automatic focus adjustment AF may not be accurately performed.

(2) Since it is impossible for the camera body 102 to determine whether or not the image has been shot with the stereo adapter attached, a camera having a playback function such as a digital still camera cannot perform playback suitable for stereo images.

(3) When a zoom lens is mounted on the camera body 102, the stereo adapter requires an angle adjusting mechanism for each reflecting surface or the like, and the configuration of the stereo adapter becomes complicated.

In general, as shown in FIG. 6, the photographing lens condenses the subject light flux C emitted from one point on the subject 101 and forms an image on one point on the image forming plane 108. In the camera, in principle, the area 10
The images of the light beams L and R overlap near the boundary between 9, 9 and 110, and the overlapping area becomes larger as the diameter of the light beam incident on the photographing lens 103 is larger. Since the sharpness of the image is reduced in the overlapping area, a sense of incongruity occurs when these one set of images are displayed as a stereo image. In addition, there is a method of removing the image of the overlapping area and displaying the image as a stereo image. However, in that case, the field of view of the stereo image becomes narrower as the overlapping area increases.

Further, in the case of a stereo image, it is necessary to adjust the convergence angle of the left and right images depending on the subject distance. However, if such an adjustment mechanism is provided in the stereo adapter, the mechanism becomes complicated and the cost increases.

The present invention has been made in view of the above problems, and has an image pickup apparatus capable of shooting a stereoscopic 3D image under optimum shooting conditions even when a stereo adapter is attached.
A first object is to provide a control method of an imaging device and a medium for supplying a program in which the control method is described to a computer.

It is a second object of the present invention to provide an image pickup apparatus capable of simplifying the configuration of a stereo adapter, a control method of the image pickup apparatus, and a medium for supplying a program describing the control method to a computer.

[0015] Furthermore, it is an object of the present invention to provide an image pickup apparatus, a control method of the image pickup apparatus, and a medium for supplying a program describing the control method to a computer for facilitating identification of a shot image by attaching a stereo adapter. This is the purpose of 3.

It is programmed so that the aperture value is set to a larger value than the program data.

Next, the operation of the camera body 1 configured as described above will be described.

FIG. 2 is a flowchart showing the operation procedure of the camera body 1.

When the power supply (not shown) of the camera body 1 is turned on (S101), the adapter detection circuit 3 detects whether or not the stereo adapter 2 is attached to the camera body 1 (S102). If the attachment of the stereo adapter 2 is detected, the process proceeds to the stereo shooting operation from step S103. If the attachment of the stereo adapter 2 is not detected, the process proceeds to the normal shooting operation. In the normal shooting operation, a general shooting operation other than shooting of a stereoscopic video is performed, but the description is omitted.

In the stereo shooting operation, first, in step S10
In step 3, the image area for photometry and distance measurement is changed not to the vicinity of the image center but to the vicinity of the center of one of the left and right divided images (for example, the left image). This will be described with reference to FIG.

FIGS. 4A and 4B are views showing the photometry and distance measurement areas of the image pickup element 8 with respect to the photographing area. In these figures, reference numeral 101 denotes a subject image. FIG. 4A is a diagram illustrating a photometry and a distance measurement area during a normal photographing operation.
2, 23, and 24 have the same center as the shooting area. The subject luminance is weighted based on the average luminances 22a, 23a, and 24a of the photometric regions 22, 23, and 24 such that the closer to the center, the greater the influence is.
Required by

Subject luminance = {3 × 22a + 2 × 23a + 24a} 6 (1) Note that reference numeral 25 denotes a distance measurement area, which also coincides with the center of the imaging area 21.

FIG. 4B is a diagram showing the photometry and distance measurement areas when the stereo adapter is attached. The photographing area 26 of the photographing areas 26 and 27 obtained by dividing the photographing screen into two right and left parts.
In the regions 28 and 2 whose centers coincide with the photographing region 26,
Using the average luminances 28a, 29a, and 30a of the pixels 9 and 30, weighting calculation is performed by the same equation as the above-mentioned equation (1) to obtain the object luminance. 31 is a distance measurement area,
This also coincides with the photographing area 26 at the center.

Thus, even when the stereo adapter 2 is attached to take a picture, photometry and distance measurement are performed near the center of the photography area 26. The reason why photometry and distance measurement are performed near one center of the photographing regions 26 and 27 and not performed near each center is that the photometry and distance measurement data are substantially the same in both cases. If done, it will be complicated including the subsequent processing.

Returning to FIG. 2, in the next step S104, the zoom lens 4b of the photographing lens 4 is driven to set the focal length to the wide (wide angle) end. That is, stereo adapter 2
Is attached, the focal length of the taking lens 4 is fixed at the wide end, and cannot be set to any other focal length.

In the next step S105, step S10
In the photometry / ranging area changed in step 3, the photometry circuit 1
After obtaining the subject brightness information by using 0, step S10
In step 6, an aperture value and a shutter speed are determined based on the subject luminance information. Then, in step S107, the aperture device 6 is driven according to the determined aperture value, and in step S108, the exposure operation of the image sensor 8 is performed according to the determined shutter speed, and step S109 is performed.
Then, the video signal obtained by the image sensor 8 is converted into a predetermined video signal by the display signal generation circuit 13, and the display device 15 performs video display according to the video signal.

In step S110, the operation in step S102 is performed until the operation of the release button 9 is detected.
The operations from to S109 are repeated. When the release button 6 is operated and a release signal is detected, the operation shifts to a stereo shooting operation.

Next, the stereo shooting operation will be described.

FIG. 3 is a flowchart showing the procedure of the stereo shooting operation.

When the operation of the release button is detected in step S110, in step S201, step S10 is performed.
The luminance of the subject in the photometry area changed in
, And the aperture value and exposure time corresponding to the subject luminance are read from the second program data 20. In the case of the normal photographing operation, the data is read from the first program data 19. In other words, during the stereo shooting operation, even if the subject has the same brightness as during the normal shooting operation, the subject is shot with the aperture further narrowed.

Next, in step S202, step S10
The object distance in the distance measurement area changed in 3 is measured by the distance measurement circuit 11. Next, in step S203, the amount of defocus is calculated based on the subject distance information obtained by the distance measuring circuit 11 and the focusing distance of the photographing lens 4 obtained from the position of the focusing lens 4a. It is determined whether it is within the range or not. If the focus shift amount is out of the predetermined range, the process proceeds to step S204, and the focus lens driving circuit 5 moves the focus lens 4a according to the focus shift amount. Then, the process returns to step S202. on the other hand,
If the defocus amount is within the allowable amount in step S203, the process proceeds to step S205.

In step S205, the object distance obtained from the focal length and the position information of the focus lens 4a is compared with a predetermined distance. If the object distance is shorter than the predetermined distance, the process proceeds to step S206, where the object is too close to the object. Is warned to the photographer, and the process returns to step S202. On the other hand, if it is longer than the predetermined distance in step S205, the process proceeds to step S207. Note that, in this case, if the subject distance is shorter than the predetermined distance, the photographing is prohibited. However, this may be configured so that the photographing is permitted only with a warning.

In step S207, step S201
The aperture motor 7 is driven in accordance with the aperture value determined in step (1), and the aperture device 6 is set to the aperture value. And step S2
At 08, the image sensor 8 performs imaging according to the exposure time determined at step S201.

In step S209, the charge signal stored in the image pickup device 8 is read out and converted into a predetermined video signal by the recording signal generation unit 12. In step S210, the charge signal is determined according to whether or not the stereo adapter 2 is attached. The recording name is added and recorded in the recording memory 14. This completes one stereo shooting operation.

In this embodiment, the images photographed during the stereo photographing operation are stereo1, stereo2,
With the record names such as stereo3,..., the images taken during the normal shooting operation are normal1, normal2,
Recording memory 14 with a recording name such as normal3,.
And it can be confirmed that it is a stereoscopic video by the recorded name.

As described above, in this embodiment, when the stereo adapter 2 is attached, the focal length of the taking lens 4 is fixed at the wide end, so that the following effects are obtained.

(1) It is not necessary to change the angle of each reflecting surface of the stereo adapter 2 and the structure is simplified.

(2) Since the diameter of the incident light beam is reduced, the overlapping area of the left and right images is reduced, and the area usable as a stereoscopic image is increased.

In the above embodiment, the stereo adapter 2
Although the photometry and distance measurement areas at the time of mounting are provided only in one of the imaging areas 26 and 27, the present invention is not limited to this. For example, the photometry and distance measurement areas are provided in both the imaging areas 26 and 27. Each of them may be provided, and an average value of each result of the photometry and the distance measurement of the photographing areas 26 and 27 may be obtained, and this may be used as a result of the photometry and the distance measurement in the subsequent processing. In this case, there is an effect that a balanced image can be obtained even when there is a left-right difference in the brightness or the like of the stereo image.

In the above embodiment, the adapter detection circuit 3
Is provided, and the adapter detection circuit 3
Although the stereo shooting operation is performed when the attachment of the camera is detected, the normal shooting operation and the stereo shooting operation may be manually switched by the mode switching circuit 16 as necessary.

In the above embodiment, the entire imaging area of the image sensor 8 is recorded and displayed as it is even during the stereo shooting operation. That is, FIG. 5 shows a set of stereo images formed on the imaging region of the imaging device 8. In FIG.
0 is an imaging area of the imaging element 8. A dotted line 201 is a boundary line that equally divides the imaging region of the imaging device 8. A hatched area indicated by 202 indicates an overlapping image area of a set of stereo images obtained by the stereo adapter 2. The overlapping image area 202 is an area where the imaging light fluxes reflected by the left and right mirrors provided on the stereo adapter 2 overlap and form an image. Therefore, the overlapping image area 20
In the image 2, the objects in different areas are in a state of being overlapped, and the definition of the image is reduced. Therefore, the image of the overlapping image area 202 is deleted, and the remaining areas 203 and 2 are deleted.
04 on the display device 15 or the recording memory 14
