Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera in which an aspect ratio can be selectively set from a plurality of aspect ratios at the time of photographing.

[0002]

2. Description of the Related Art Equipped with a trimming shooting function that enables printing by specifying a partial area on a film shooting screen,
A camera in which the aspect ratio (aspect ratio) of the screen in this trimming photographing can be selected for each photographing is proposed in Japanese Patent Laid-Open No. 62-163033. In such a camera, the information of the selected aspect ratio is stored in the magnetic recording section provided for each frame of the film, and by reading this information at the time of printing,
A print with the selected aspect ratio is obtained.

By the way, in the camera, a mode setting for selectively setting an exposure control mode such as an aperture priority exposure mode and a shutter priority exposure mode, and a shooting function mode for inputting shooting auxiliary information such as ISO sensitivity and date of film. Means and operation means for selecting the content of the shooting auxiliary information to be input when the mode setting means is operated to the shooting function mode. , Performs the operation of selecting the contents of shooting auxiliary information, the operation of setting the exposure control mode, and the operation of selecting the aspect ratio. In this way, if the photographer operates the release button, proper photography is performed in the desired exposure mode and aspect ratio.

[0004]

However, in order to improve operability and the like, each operation means for selecting photographing auxiliary information and aspect ratio is part of the camera body (for example,
(In the vicinity of the Leeds button), they may be arranged collectively, and in this case, for example, while operating the selection operation means of the shooting assistance information, the operation means for selecting the aspect ratio is mistakenly operated, A situation may occur in which the set aspect ratio is switched without the photographer's knowledge, and it is not possible to photograph with a desired aspect ratio. Further, if the aspect ratio is switched when it is not necessary, there is also a problem that power is unnecessarily consumed for this switching control.

Note that once the mode setting means is operated to the photographing function mode, the aspect ratio set immediately before that is automatically switched to a predetermined (for example, standard) aspect ratio, and the mode setting means is exposed again. If the photographer is made to set the aspect ratio again when returning to the control mode, it is possible to prevent photographing with an incorrect aspect ratio.

However, if an aspect ratio setting operation is required after the operation of the mode setting means when photographing a moving object, a photo opportunity may be missed.

Therefore, a first object of the present invention is to provide a camera in which the aspect ratio is not switched except when necessary. A second object of the present invention is to provide a camera capable of promptly photographing after operating the mode setting means.

[0008]

In order to achieve the above object, the first invention of the present application has a mode setting means for setting a camera mode and an aspect ratio selecting means for selectively setting an aspect ratio. The camera is provided with aspect ratio switching prohibition means for prohibiting the aspect ratio selection means from switching the aspect ratio when the specific mode is input by the mode setting means. In addition,
It is desirable that the specific mode mentioned here is, for example, a mode for setting a photographing function other than the exposure control mode.

According to such a camera, when the mode setting means is set to the specific mode, the aspect ratio is not switched even if the aspect ratio selecting means is operated. Therefore, it is possible to reliably prevent a situation in which the aspect ratio is switched due to an erroneous operation while the operation of selecting the content of the specific information is being performed.

Further, in the second aspect of the present invention, when the setting mode by the mode setting means is switched to the specific mode and then returned to the original mode, the aspect ratio is selected at the first mode switching. The camera is provided with an aspect ratio restoring means for setting the aspect ratio selected by the means.

According to such a camera, even if the mode setting means is changed from the exposure control mode to the photographing function mode (specific mode) to change the photographing auxiliary information after setting the desired aspect ratio, At this time, even if the aspect ratio selecting means is mistakenly operated, if the mode setting means returns to the exposure control mode, the aspect ratio returns to the original setting ratio. Therefore, it is possible to take a picture immediately after operating the mode setting means, and it is possible to avoid missing a photo opportunity.
