Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a camera capable of selecting one from a plurality of photographing aspect ratios.

[0002]

2. Description of the Related Art Conventionally, as described in JP-A-62-163033 and JP-A-4-1974450, there is provided a trimming photographing for designating a print of only a partial area in a photographing screen, A camera has been proposed in which the aspect ratio can be selected.

FIG. 6 shows the three types of aspect ratio differences and the trimming area. Figure 6 (a)
FIG. 4 is a diagram showing a region printed at the time of printing when the aspect ratio switching value “H” is selected and photographed, and the aspect ratio is about 1: 1.8. FIG. 11B is a diagram showing a region that is similarly printed during printing when the aspect ratio switching value “L” is selected and photographed, and the aspect ratio is about 1: 1.5. FIG. 11C is a diagram showing a region which is printed at the same time when printing is performed by selecting the aspect ratio switching value “P”, and the aspect ratio is about 1:
2.8.

These aspect ratio switching values are "H",
Information indicating "L" or "P" is stored in the magnetic storage portion of each frame of the film, and by using this magnetic information at the time of printing, a print having a desired aspect ratio can be obtained. When this aspect ratio switching is performed, the inside of the finder is electrically displayed using an LCD or the like as in FIG. Furthermore, when either the "H" or "L" mode is switched to the "P" mode, the finder optical system also uses a motor or the like as shown in FIG.
The switching is performed as shown in, to increase the magnification in the "P" mode. Conversely, from "P" mode, "H" or "L"
When switching to either one of the modes, the finder optical system is switched as shown in FIG. 7 (b) to reduce the magnification in the "H" or "L" mode.

[0005]

SUMMARY OF THE INVENTION In the above conventional example,
It was found that the following problems occur when the aspect ratio is switched while looking through the viewfinder.

When switching between the "P" mode and the "H" or "L" mode, the LCD display of the finder has an immediate response, so that the mode is switched immediately. However, the drive of the founder optical system by the electric motor or the like is naturally delayed. Accompanied by.

Therefore, for example, if the finder optical system is switched after switching the LCD finder having an immediate response first, when the "P" mode is set, as shown in FIG.
As shown in FIG. 5, the upper and lower parts are masked by the LCD, and then the optical system is driven so that the finder magnification becomes large. After the drive is finally stopped, the field of view seen by the photographer is narrower than when the drive of the optical system is started. On the contrary, when the "P" mode is switched to either the "H" or "L" mode, after the driving is finally stopped, the field of view seen by the photographer is wider than that at the start of driving. .

Similarly, if the finder optical system is switched first, and then the LCD finder having a prompt response is switched later, the reverse of the above, the system consistency in any case. I can't get it.

Further, there is a problem in that it is not preferable to fix the order unconditionally because the order of the field of view display on the LCD of the finder and the driving of the optical system is preferred by the photographer.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a camera capable of displaying a field of view in a finder and switching between changes in image magnification without a sense of discomfort.

[0011]

In order to solve the above problems, the camera of the present invention comprises, in claim 1, display means in a finder such as an LCD and means for driving a finder optical system. , And has an order selecting means that makes it possible to select an operation order. Further, in the second and third aspects, there is provided means for recording information of the selected photographing aspect ratio on a film by magnetic recording or imprinting.

[0012]

According to the present invention, by appropriately selecting the order of the display in the finder and the switching operation of the finder optical system by the photographing selection means, the LCD visual field display and the image magnification in the finder can be switched. It can be done without any discomfort.
