DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera, and more particularly, to a first exposure mode for exposing a normal size image on a film surface and a second exposure mode for exposing an image having a size different from the normal size screen. The present invention relates to a display device of a camera that can appropriately select an exposure mode.

[0002]

2. Description of the Related Art In recent years, various cameras capable of switching a photographing screen size which is a size of an exposure image on a film surface have been proposed and commercialized. In such a camera, it is necessary to display various contents related to a photographing screen size and the like. Japanese Patent Laid-Open No. 1-2051 discloses a camera capable of switching the photographing screen size and capable of displaying a photographing frame number which is an exposure frame number for each size.
The camera disclosed in Japanese Patent Publication No. 39 is a camera capable of switching a shooting screen size between a normal size, that is, a so-called full size and a half size. The number of frames and the number of remaining frames can be displayed simultaneously with the display of each shooting mode in accordance with the shooting mode (exposure mode) of each shooting screen size.

Another conventional camera capable of switching the photographing screen size is a camera which can switch the photographing screen size during photographing, and has a shorter vertical dimension and a wider lateral dimension as compared with a normal camera. Some displays the total number of frames shot in both panorama size and normal size shooting modes.

[0004]

However, the camera disclosed in Japanese Patent Laid-Open No. 1-205139 cannot switch the photographing screen size during photographing.
It was not easy to use for photography in which various sizes were selected depending on the subject.

[0005] In the above-mentioned conventional camera capable of displaying the total number of frames taken in both the panorama size and the normal size, it is possible to perform shooting while switching the shooting size, but it is only possible to perform a single shooting up to each. I don't know if the shooting was done in the screen size shooting mode or in both shooting modes. Therefore, when requesting film development and printing, for example, there is a problem that it is not possible to determine whether or not to attach a panorama sticker indicating that panorama size processing is required.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problem. In a camera in which the size of a screen to be exposed can be appropriately selected from a normal size and a size different from the normal size, a camera having a size different from the normal size is used. The purpose of the present invention is to provide a camera that displays whether or not shooting has been performed or the number of frames shot in each size so that a photographer can recognize information regarding the shooting size during shooting or at the end of shooting. And

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a main block configuration diagram of a camera according to a first embodiment of the present invention. This camera is a camera that can appropriately select a photographing screen size that is a size of an exposure image on a film surface. The setting screen size is a normal size, a so-called full size, and a size different from the normal size screen, and is set to a panorama size in which the vertical dimension on the film surface is narrowed and the aspect ratio is changed. Make it possible. A mode for exposing the normal size image is set to a normal mode (hereinafter, referred to as a first exposure mode).
The mode for exposing the image of the panorama size is referred to as a second exposure mode, that is, a panoramic mode (hereinafter, referred to as a P mode). Note that the switching operation can be performed even during shooting. And this camera is
It has a built-in LCD display unit which is a display means of shooting size / frame number information. The display unit has the panorama size in addition to the total number of shooting frames which is the number of exposure frames in the first and second exposure modes. , The number of exposure frames in the second exposure mode, the number of panorama size photography frames, and the like can be displayed.

The structure of this camera is as follows: a CPU 1 for controlling each control element of the camera, an R-SW2 as a shutter release switch, and a P / N-SW3 as a switch for switching between a P mode and an N mode of a shooting mode. A DX signal input terminal 8 which is a DX contact of the film, an LCD 4 for displaying photographing size / frame number information, a film driving motor 11, an H-type driving circuit 12 for driving the film driving motor 11, and a film 9. A photoreflector 10 which is a detection unit of the number-of-frames-to-be-photographed counting means for each photographing size by detecting the passage of the perforation, a photographing optical system such as a photographing lens, a shutter, and an aperture (not shown), and a normal photographing screen size. It is configured by a mechanism for switching a photographing size between a panorama size and the like.

The CPU 1 includes, in addition to the control section, control means for detecting the presence or absence of photographing in the P mode, a normal photographing frame number FN which is the number of exposure frames in the N mode, and P A first counting means for calculating the total number of frames F to which the panorama frame number FP, which is the number of exposure frames in the mode, is added;
A second counting means for counting the number of shot frames of only P is also provided.

The display unit of the LCD 4 includes a display unit for displaying the total number of frames F to be shot, a panorama mark "P" displayed when shooting is performed in the P mode, and a display unit for displaying the number of frames for panorama shooting FP. It consists of. A film end mark "E" is displayed on the display section of the total number of shot frames F when the film is not loaded in the camera and when the rewinding is completed. Further, the H-type drive circuit 12 includes:
As shown in FIG. 1, this circuit is composed of four transistors, and supplies a current Iu to the film driving motor 11 when the film is wound and a current Ir when the film is rewound.

The display operation of the camera of the present embodiment having the above-described configuration at the time of shooting will be described with reference to FIG. First, a description will be given of a case where shooting is performed only in the N mode. First, an end mark E blinks on the LCD 4 before the film is loaded, as shown in a display 4a of FIG. Then, when the film 9 is loaded and the photographing is executed, the total number of photographed frames F is displayed as shown in a display 4b of FIG. In this case, since the photographing is performed in the normal size, the frame number F matches the normal photographing frame number. Subsequently, when a predetermined number of frames have been shot and the film is rewound, the end mark “E” blinks as shown in a display 4c in FIG.

Next, the display operation in the N mode shooting will be described in detail with reference to FIG. 3 which is a flowchart of the subroutine "display I". First, in step S101, when the release signal is turned on, the process proceeds to step S10.
Proceed to 2 to check for the presence of the film 9. If there is no film, the process jumps to step S112 to display the film end mark "E" and ends this routine. If a film is loaded, step S1
Go to 03. Then, the photographing mode is checked. If the mode is set to the P mode, the process proceeds to step S104, and the display process in the P mode is executed. The operation will be described later. On the other hand, if the mode is set to the N mode, the process jumps to step S113.

In step S113, one frame is counted by a counter for the number FN of photographing frames of the normal size. Subsequently, the number of frames FN is stored in the memory (step S114). Then, the added value of the number of frames taken in the normal size and the panorama size (= FN + FP
) Is obtained (step S115), and the added value is stored in the memory as the total number of shot frames F (step S11).
6). Then, the process proceeds to a step S117, where the total number F of photographed frames is displayed on the LCD 4 (see the display 4b in FIG. 2), and the present routine is terminated. In this case, since the panorama shooting has not been performed, the panorama mark “P” and the panorama shooting frame number FP are not displayed.

The film of one frame length is wound up every time one frame is shot. At that time, the film drive motor 11 is driven by the winding current Iu of the H-type drive circuit 12. In addition, the amount of winding is the photoreflector 10
, One frame is detected.

Subsequently, when the photographing of a predetermined number of frames is completed and the film rewind operation is started, a subroutine "film rewind" shown in FIG. 4 is called, and the film rewind is executed. First, during filming, the film wound around the cartridge runs out, and when the film end is detected, the winding is forcibly stopped. The detection of the film end is performed by detecting a state in which the output waveform of the photoreflector 10 does not change even when the winding current Iu is supplied to the film drive motor 11 (step S12).
1). Subsequently, in step S122, the film drive motor 11 is driven by the rewind current I via the H drive circuit 12.
The film is rewound by reverse driving by r. Then, when it is detected that the output waveform of the photoreflector 10 does not change, it is determined that rewinding is completed (step S).
123).

Next, the memory numbers FN and FP and the memory value of the total number F of shot frames, which is the added value, are cleared (steps S124 and S125). Then, the stored information on whether or not the panorama shooting stored in step S105 in the subroutine of FIG. 3 has been executed is checked (step S126). If the storage information indicating that the panorama shooting has been performed is stored, the process proceeds to step S127. In this case, since the panorama shooting is not performed, the process proceeds to step S130.

In step S130, the total number of frames F is displayed, the panorama mark "P", the number F of panorama frames.
Turn off the P display. And step S
The program proceeds to 131, where the film end mark "E" is flashed and displayed, and this routine ends (see display 4c in FIG. 2). As described above, when shooting is performed only in the normal shooting mode, only the total number of shots F is displayed in the display of the number of shots during shooting, so the photographer is notified that panorama shooting is not being performed. Can be easily recognized. Furthermore,
Since the panorama mark “P” is not displayed even at the end of shooting, it can be confirmed that panorama shooting was not performed.

Next, a description will be given of a display processing operation when one or more images of the panoramic size are photographed during photographing of the normal size. The display state of the LCD 4 at that time is shown in displays 4a, 4d, and 4e in FIG. That is, the film end mark “E” is blinking before the film is loaded. After the film is loaded and the photographing is started, both the N mode and the P mode are selected, and both the normal size and the panoramic size are photographed, the normal mode and the normal mode are displayed as shown in a display 4d in FIG. And the total number of frames F, which is an added value of panorama shooting, 15, the panorama mark "P", and the number of frames FP shot at panorama size 3, are displayed. In this specific example, the number of frames FN for normal shooting is 12 frames from F-FP.

When the photographing of the film is completed and the rewinding is completed, the film end mark "E" blinks and the panorama mark "P" blinks as shown in a display 4e of FIG. You. With this display, the photographer can know that the photographed film has at least one frame in a panoramic size, and the "panoramic seal" required when requesting the development and printing of the film. Can be stuck on the patrone without getting lost.

In the above display processing operation, the display processing at the time of P mode shooting will be described in detail with reference to the flowchart of the subroutine "display I" in FIG. In the above flowchart, it is determined in step S103 whether or not the camera is in the P mode. Step S1 before that
The processes of 01 and S102 are the same as those already described in the display operation at the time of normal shooting.

In step S104, the number of shot frames FP counter in panorama size is counted. Subsequently, panorama shooting storage information for storing that panorama shooting in the P mode has been performed is stored (step S105). Then, the flow advances to step S106 to store the number of shot frames FP in the panorama size. Further, an addition value (= FN + FP) of the number of shot frames in the normal size and the panorama size is obtained, and the added value is stored as the total number F of shot frames (steps S107 and S108). Then, Step S109,
Proceeding to S110, S111, the total number F of shot frames, the panorama mark "P" based on the panorama shooting storage information, and the number of panorama shot frames FP are displayed on the LCD 4 (see 4d in FIG. 2). The display of this specific example is
This indicates that the total number of frames F is 15, which includes panoramic images, and that the number of frames is 3. After these displays, this routine ends.

Note that the film having a length of one frame is wound up every time one frame is shot, but the amount of winding corresponding to the panorama size is increased during the panorama shooting.
Is detected by

Subsequently, when the photographing of a predetermined number of frames is completed and the operation proceeds to the film rewind operation, a subroutine "film rewind" shown in FIG. 4 is called, and the film rewind is executed. The process from the film end detection process in step S121 to the process of clearing the total number of shot frames in step S125 is the same as the process in the above-described N mode shooting. Thereafter, in step S126, it is determined whether or not the stored information as to whether or not the panorama shooting in step S105 in the subroutine of FIG. 3 has been executed. in this case,
Panorama shooting storage information is stored, and step S1
Proceed to 27 or lower.

In steps S127 to S129, the display of the total number of shot frames F and the display of the number of panorama shot frames FP are turned off, the panorama mark "P" and the film end mark "E" blink, and this routine is executed. The process ends (see display 4e in FIG. 2).

As described above, when the N mode shooting including the P mode shooting is performed, the panorama shooting frame number FP is displayed simultaneously with the total shooting frame number F during the shooting, so that the photographer can clearly shoot. You can know the information content of the size. Further, when the panorama mark “P” is displayed at the end of the photographing, the photographer can easily recognize that there is at least one or more panoramic photographing films in the photographed film. Therefore, for example, it is possible to attach a "panoramic seal" required when requesting film development and printing to a film development laboratory without doubt.

Next, a camera according to a second embodiment of the present invention will be described. This camera differs from that of the first embodiment in the display contents of the photographing information on the LCD 41, which is the display means of the photographing size / frame number information. However, the configuration of the other control elements is the same as that of the first embodiment shown in FIG. Further, also in the present camera, switching between the N mode for exposing a normal size image and the P mode for exposing a panoramic size image is possible even during shooting. As shown in FIG. 5, the display content of the photographing information on the LCD 41 is simplified by omitting the display of the panorama photographing frame number FP on the display 4d in FIG.

The display operation of this camera is the same as the display of the first embodiment when photographing only in the N mode, as shown in the displays 41a, 41b and 41c in FIG. The blinking display of the film end mark “E” and the total number F of photographed frames are displayed on the LCD 41. On the other hand, when shooting in the P mode is included, the display 41 is displayed during shooting.
As shown in FIG. 4D, the total number of shot frames F obtained by adding the number of frames of normal and panoramic shooting and a panorama mark "P" are displayed. However, the panorama shooting frame number FP is not displayed. Then, at the end of the photographing, the film end mark “E” and the panoramic mark “P” are blinkingly displayed as shown in the display 41e.

The processing of the display operation will be described with reference to the flowchart of the subroutine "display II" in FIG. 6. This subroutine "display II" is different from the subroutine "display I" in FIG. 3 in the first embodiment. Step S111
In that the display processing of the panorama shooting frame number FP is not performed. Other processes are the same as those of the subroutine "display I". That is, the processes of steps S101 to S117 except for step S111 of the subroutine "display I" are the same as the processes of steps S201 to S216 of the subroutine "display II".

The film rewinding process after the photographing of a predetermined number of film frames is completed in the camera of this embodiment is not particularly shown, but the subroutine "film rewinding" of the first embodiment of FIG. In contrast, since the number of panorama shooting frames FP is not originally displayed,
Panorama shooting frame number F in steps S127 and S130
The only difference is that there is no display off process for P.

As described above, the camera of this embodiment is
Not only when shooting in P mode only, but also during shooting in N mode
The panorama mark “P” is also displayed when shooting in the mode, and the photographer can recognize that panorama shooting has been performed. At this time, the number of panoramic frames is not displayed, and only the total number of frames is displayed, so that the display is simplified and is easy to see. Further, similarly to the camera of the first embodiment, when the panorama mark “P” is displayed at the end of the photographing, the photographer can easily recognize that there is a photographing frame of a panoramic size in the photographing film. it can.

In the cameras of the first embodiment and the second embodiment, the size of the photographing screen is changed by
The switching operation between the normal size and the panorama size is enabled, but the present invention is not limited to this, and can be applied to a camera that can switch between normal size shooting, trimming shooting, and half size shooting.

[0035]

As described above, the camera according to the present invention performs display based on the mode switching information in accordance with the switching of the exposure mode for switching the exposure screen size. It is possible to recognize that the size has been switched. Furthermore,
Even at the end of shooting, there are many remarkable effects, such as being able to identify whether or not a shot film exists by switching the exposure screen size in the shot film.
