Abstract

PURPOSE:To prevent photographing action from being continued without being aware that the aspect ratio is reset to a specified aspect ratio by displaying that the aspect ratio is restored to the specified aspect ratio by a resetting means. CONSTITUTION:The optional aspect ratio is selected from three kinds of aspect ratio by a selection switch 21, and the selected aspect ratio is displayed by a display circuit 24. Next, whether or not the display of the aspect ratio is flickered by the display circuit 24 is discriminated. In the case of discriminating that the display is not flickered, AF and AE are performed by a range-finding circuit 13 and a photometry circuit 12. Thereafter, whether or not an SW2 is turned on is discriminated. When it is turned on, exposure is performed by a shutter control circuit 14 and a diaphragm control circuit 15, and further the selected aspect ratio is stored in the magnetic storage part of film by a magnetic head 9. Then, the selected aspect ratio is reset to the aspect ratio previously set and the display is flickered by the display circuit 24.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera having a selection means for selecting one of a plurality of aspect ratios (aspect ratio of a photographing screen or a print screen).

[0002]

2. Description of the Related Art The applicant of the present invention has a camera having a selection means for selecting one of a plurality of shooting aspect ratios and a means for returning the shooting aspect ratio to an initial setting value for each frame shooting.
Further, there is proposed a camera equipped with a selection means for selecting a mode for returning the shooting aspect ratio to the initial setting value and a mode for not returning it for each frame shooting (for example, Japanese Patent Application No. 4-1974).
No. 50).

According to the above proposal, by providing the means for returning the photographing aspect ratio to the initial setting value for each frame photographing,
It is possible to prevent forgetting to return when selecting an aspect ratio other than the default shooting aspect ratio, and select a mode to return to the default shooting aspect ratio for each frame shooting and a mode not to return By providing the selection means for performing the shooting, it is configured so as to be able to cope with the case where it is desired to continuously perform shooting with the same aspect ratio. Furthermore, the above-mentioned proposal also discloses a display unit that displays the shooting aspect ratio when selected.

[0004]

However, according to the above-mentioned applicant's proposal, when the mode for returning the shooting aspect ratio to the initial setting value for each frame shooting is selected, the shooting aspect ratio goes against the will of the photographer. Since it is forcibly reset, the photographer may continue shooting without noticing the reset.

In particular, if the shooting aspect ratio to be reset is not the aspect ratio for exposing the widest area of the plurality of shooting aspect ratios, an area narrower than the area intended by the photographer will be printed and the subject will be printed. There was a possibility that a serious problem such as cutting off a part of the might occur.

The present invention has the following objects in order to solve the conventional problems.

(1) The aspect ratio selected by the photographer is
It is prevented that photography is continued without noticing that the predetermined aspect ratio has been reset (corresponding to claim 1).

(2) Since the display means for displaying the selected aspect ratio and the means for displaying that the selected aspect ratio is reset to the predetermined aspect ratio are provided, the aspect ratio which is always selected is It is possible to shoot while confirming what it is, and to prevent the user from continuing shooting without noticing that the aspect ratio selected by the photographer has been reset to a predetermined aspect ratio. Supported by).

(3) The size of the camera can be reduced and the cost can be reduced by using two display means as one (corresponding to claim 3).

(4) By making the symbols of the display means common, the display can be simplified and an easy-to-understand display configuration can be realized. Further, the size of the camera can be reduced and the cost can be reduced because the display means can be made small (corresponding to claim 4).

(5) A mode in which the aspect ratio is reset and a mode in which the aspect ratio is not reset can be selected, and an easy-to-use camera can be realized according to the purpose of use of the photographer, and when the mode to be reset is selected. Prevents the photographer from continuing to photograph without noticing that the photographer has been reset (corresponding to claim 5).

(6) It is possible to shoot while always confirming what the selected aspect ratio is, and whether or not the mode is a mode in which the aspect ratio is reset (corresponding to claim 6).

(7) By using two display means as one, it is possible to reduce the size and cost of the camera.
Moreover, since it can be confirmed that the mode is to be reset before photographing, it is possible to call the photographer's attention earlier (corresponding to claim 7).

(8) If the blinking time is divided by a timer or the like, it may be forgotten that the camera is reset when the shooting interval exceeds the timer time. However, according to the present claim. It is possible to prevent the above problems (corresponding to claim 8).

(9) By using two display means as one, it is possible to reduce the size and cost of the camera.
Moreover, since it can be confirmed that it was reset after shooting,
It is possible to call the photographer's attention (corresponding to claim 9).

(10) If the blinking time is divided by a timer or the like, it may be possible to forget that it was reset when the shooting interval exceeds the timer time. However, according to the present claim. In this case, it becomes possible to prevent the above problems (corresponding to claim 10).

[0017]

In order to achieve the above object, in the present invention, the display means for displaying that the aspect ratio has returned to the predetermined aspect ratio by the reset means is provided, and the predetermined aspect ratio is provided. It is possible to prevent continuous shooting without noticing that the ratio has been reset.

According to a second aspect of the present invention, a first display means for displaying the selected aspect ratio and a second display means for displaying that the aspect ratio has been reset are provided, and the selected aspect ratio is always confirmed. While it is possible to take a picture, the action and effect of claim 1 are left as they are.

According to a third aspect of the present invention, by making the display means common to the two of the second aspect, it is possible to reduce the size and cost of the camera. Moreover, the action and effect of claim 2 are left as they are.

According to the present invention, when the resetting means returns the aspect ratio to the predetermined aspect ratio, the symbol indicating the predetermined aspect ratio of the display means is made to blink, thereby making the symbol of the display means common. The display can be simplified and the display can be easily configured. Moreover, the downsizing of the display enables downsizing and cost reduction of the camera.
