Note that, here, regarding other operations such as auto-zoom when the switches SW1 and SW2 are turned on,
Since it is similar to the already known camera, it is omitted here. The structure for switching the shooting range by shifting the shift lens is not described in detail, but the correction lens in the camera with anti-vibration function is shifted with respect to the shooting optical axis to decenter the shooting optical axis. Is already known,
It is easy to apply this technique to the shift of the shift lens, and therefore it is omitted.

As described above, in this first embodiment, the line of sight is sent (pointed) to the place to be photographed in the finder, and the shift lens in the photographing optical system is set as shown in FIGS. By shifting so that you can see what you see, you can select the place you want to take in the viewfinder.

Further, even if it is said that an arbitrary range is photographed by sending a line of sight, it is not good in terms of specifications to enclose the range to be photographed with the line of sight, so as shown in FIG. In the present embodiment, which of the items B to I) is to be selected is determined based on the line-of-sight data.

(Second Embodiment) In the second embodiment, it is assumed that a camera capable of panoramic image pickup has the above-mentioned function incorporated therein. The circuit configuration of the camera is the same as that shown in FIG.

Conventionally, in a camera capable of switching between normal shooting and panoramic shooting, when panoramic shooting is performed,
You can either take a panoramic photo based on the panorama index in the viewfinder for normal shooting, or use the viewfinder with the top and bottom of the viewfinder masked for shooting. Since the viewfinder for normal shooting is the standard, panoramic shooting for taking spacious photos is difficult to see because the viewfinder is small and difficult to see.

Therefore, in the second embodiment, it is assumed that the viewfinder is large and easy to see in view of panoramic photography, and at the time of normal photography, as shown in FIGS. Enter with.

By doing this, during panoramic photography,
You can shoot with a viewfinder that is easier to see, and when shooting in the normal format, you can take a picture with a better composition by deciding the part you want to shoot from the panorama viewfinder.

Next, a second embodiment will be described with reference to FIGS.

12 to 15, reference numerals 1201 and 13
01, 1401, 1501 is a viewfinder for panoramic photography, 1202, 1302, 1402, 1502 are the eyes of the photographer, 1203, 1303, 1403, 1503 are images projected on film, 1304, 1404, 1504.
Is a shooting range display to be imprinted on the film. Also,
Reference numerals 1305, 1405, and 1505 represent the line of sight of the photographer.

Here, FIG. 12 shows an example of performing panoramic photography. What is seen in the panoramic viewfinder 1201 is a film in a panoramic format (a range that covers the upper and lower sides of the normal photographing range) as shown in an image 1203. Imprinted on.

FIGS. 13, 14 and 15 show an embodiment for photographing in a normal format.

In FIG. 13, the photographer's eyes 1302 (line of sight 1
Reference numeral 305) shows a case where the panoramic viewfinder 1301 is oriented almost to the center. In this case, the microcomputer 1 does not shift the shift lens, and the photographing range display in the viewfinder is brought to the center like 1304.
Then, in this state, when the photographer performs the second stroke operation of the release button (not shown) and the SW2 is turned on, the microcomputer 1 causes the microcomputer 1 to display the photographing range display 130.
Control is performed so that the subject within 4 is printed on the film. As a result, a subject such as 1303 in FIG. 13 is printed on the film.

Next, FIG. 14 shows an example in which the photographer's eyes 1402 (line of sight 1405) are directed to the left side of the panoramic viewfinder 1401, and in this case, the microcomputer 1 shifts the shift lens to the left side, and The shooting range display in the viewfinder is also moved to the left like 1404.
Then, in this state, when the photographer performs the second stroke operation of the release button (not shown) and the SW2 is turned on, the microcomputer 1 causes the microcomputer 1 to display the photographing range display 140.
Control is performed so that the subject within 4 is printed on the film. As a result, a subject such as 1403 in FIG. 14 is printed on the film.

Next, FIG. 15 shows an example in which the photographer's eyes 1502 (line of sight 1505) are directed to the right side of the panoramic viewfinder 1501. In this case, the microcomputer 1 shifts the shift lens to the right side, and The shooting range display in the viewfinder is also moved to the right side like 1504.
Then, in this state, when the photographer performs the second stroke operation of the release button (not shown) and the SW2 is turned on, the microcomputer 1 causes the microcomputer 1 to display the photographing range display 150.
Control is performed so that the subject within 4 is printed on the film. As a result, a subject as shown by 1503 in FIG. 15 is printed on the film.

According to each of the above-described embodiments, in a camera having a viewfinder capable of seeing an actual shooting range or a range wider than the normal shooting range, the range desired to be taken by the user in the viewfinder is selected by the line of sight. By making it possible, for beginners it will be possible to take pictures with better composition automatically, and for intermediate and advanced people it is also possible to check the surroundings of the shooting range, so better trimming is possible and at the same time the line of sight Trimming has the effect of increasing the shutter chance.

(Modification) In the second embodiment, the viewfinder is based on panoramic photography.
The present invention is not limited to this, and may be a high-definition viewfinder based on high-definition shooting.
