The above object is attained by a camera self-control device having a display control means for controlling the display function so that the self-photographing number display is performed in response to the number setting of the self-photographing number setting means. FIG. 1 is a block diagram showing an example of an embodiment of the present invention. In FIG. 1, reference numeral 1 denotes a microcomputer which receives operation information of a release switch 2 and a self-switch 3 from the microcomputer 1 and which controls a shutter drive system 4 and a film feeder. The system 5, the LCD driver 6, and the LED driver 7 are controlled. As is well known, the release switch 2 is a first-stage switch 2a.
When the first stage switch 2a is depressed, a start signal of the AE control and the AF control is given to the microcomputer 1 when the first stage switch 2a is depressed, and the depression operation is performed to the second stage switch 2b. Thus, a release signal is given to the microcomputer 1. A self-switch 3 is a push-button switch which requests the microcomputer 1 to set a self-mode and, as described later, is operated by a key operation.
Is given information on the number of self-photographs. LCD driver 6 is L
The CD display 8 is driven. The LCD display 8 has a number display section 8a and a mode display section 8b, and displays the number of film shots with a "FILM" display and a number display.
The number of self-photographs is displayed by the "F" display and the number display. L
The ED driver 7 drives the self-display LED 9. The self-display LED 9 performs a well-known self-operation display, and indicates, for example, that self-photographing has been performed in the order of lighting, blinking, and extinguishing. The AE control system and AF
Illustration of the control system is omitted. FIGS. 2 and 3 are control flowcharts for the configuration of FIG. 1. Terminals a and b in FIG. 2 are connected to the terminals of the same reference numerals in FIG. Hereinafter, FIG. 1 and FIG.
The operation of the configuration will be described. When the key operation of the self-switch 3 is performed, the self-switch 3 is recognized to be turned on in step 10 and the self-mode setting process is performed in step 11, and the process proceeds to step 12, where the number N of self-photographs is incremented by +1. Set “1”. Then, the process proceeds to step 13, where the display of the number of photographed films on the LCD display 8 is switched to the display of the number of self-photographed images, and the set number of self-photographed images "1" and "SELF" are displayed on the LCD display 8. After that, through the keying release determination in step 14 and the upper limit number determination in step 15, the first
The ON / OFF determination of the step switch 2a is started. Step 14
If the self-switch 3 is still pressed, the flow advances to step 15 until the pressing operation is released. The upper limit number N _{MAX in} step 15 is the remaining number of shootable films, and the set number of self-shots N is equal to the upper limit number N _MAX.
If it is smaller than or equal to the value, the process immediately proceeds to step 16, and if it is larger, the process proceeds to step 16 via steps 17 and 18. In step 17, the number N of self-photographed images is reset to "0".
Is given a number display of “0”. Assuming that the first-stage switch 2a is not pressed, steps 16 to 10
Then, the update setting operation of the self-photographing number N is repeated.
That is, the update setting of the number of self-photographs “2” and the update display corresponding thereto are performed in steps 12 and 13 by the second key operation of the self-switch 3, and thereafter, similarly,
An update setting and an update display of the number of self-photographs N according to the number of times of keying operation of the self-switch 3 are performed. If the self-shot number N is exceeds the maximum number N _MAX, step 17,
At 18, the number of self-photographs N is reset to “0” and “0”.
The display is performed, and a new number N of self-photographs can be set. If there is no request for self-photographing, the process immediately proceeds to step 16 from step 10, and the self-mode setting processing and the operation for setting the number of self-photographs are not performed. When the first-stage switch 2a is depressed, the process proceeds from step 16 to step 19, where the well-known AE control and AF control are performed, and then the process proceeds to step 20. In step 20, it is determined whether the second-stage switch 2b is on or off.
From 0, the process proceeds to step 21 to determine whether or not the mode is the self mode based on the self mode setting process of step 11. If the self mode is set, step 2
Step 1 is entered from step 1 and the number of self-photographs N is “0”.
Is determined, and if it is not “0”, the process proceeds to step 23, in which the self-timer is started in step 23, the self-operation is displayed in step 24, the time-up is determined in step 25, the self-timer is reset in step 26, and By the shutter release control in step 27,
Perform self-shooting. The self-operation display is performed by controlling the self-display LED 9 as described above. The shutter release control in step 27 is performed by controlling the shutter drive system 4. After the shutter release control in step 27, the process proceeds to step 28, in which the film is fed through the control of the film feeding system 5, and then, in step 29, the number N of self-photographs is decremented by -1, and the process proceeds to step 30. . Step 3
At 0, it is determined whether or not the number of self-photographs N has become “0”, in other words, whether or not the number of self-photographs corresponding to the set number of self-photographs N has been performed. If the number of self-photographs N is not “0” in step 30, the update of the number of self-photographs N in step 31 is performed, and the process proceeds to step 23.
Then, the closed loop of steps 23 to 31 is circulated until the number N of self-photographed images becomes “0”, and self-photographing is repeated. As a result, the number N of self-photographed images becomes “0”, and the process proceeds from Step 30 to Step 32, where the display control of the self-mode and the number of self-photographed images is released, and Step 33
Move to On the other hand, if the number of self-photographs N is “0” in step 22, that is, if step 22 is entered with the number of self-photographs reset to “0” in step 17, the process immediately proceeds to step 32. . Therefore, when the self-photographing is to be stopped after the self-photographing number N is set, the key operation of the self-switch 3 is performed until the self-photographing number N is reset to “0” in step 17, and the first switch of the release switch 2 When the stage and the second stage switches 2a and 2b are pressed, the self mode is released, and there is no need to separately provide a release switch. On the other hand, if the self mode is not set in step 21, the process proceeds from step 21 to step 34,
The process proceeds to step 33 through normal controls such as shutter release control, film feeding control, and counting of the number of film shots in accordance with the pressing operation of the second-stage switch 2b. Step 33
Then, the number of film shots is displayed, and the process returns to step S10. As described above, according to the present invention, the number of self-photographs is set according to an external operation, and the number of self-photographs corresponding to the set number of self-photographs is performed. Therefore, the desired number of self-photographings can be performed without repeating the self-operation. Also, each time a self-shooting is performed, the set number of self-shooting is subtracted and the self-shooting number display is updated and displayed. It is possible to easily recognize whether the operation is performed, and to provide an effect of giving advice to a person who is the subject. Further, according to the present invention, the number of self-photographs is set according to the number of times a self-switch is pressed for setting the self-mode, and the self-photograph number is reset when the number of self-photographs exceeds the upper limit. When the number of self-shots is reset, the self-shot is terminated without performing the self-shot, so that there is no need to provide an operation switch other than the existing self-switch to cancel the self-mode. . In addition, the upper limit number of sheets can be set to the remaining number of shootable films. According to this, it is impossible to set the number of self-shot images exceeding the remaining number of shootable films. This has the effect of notifying the camera user. Further, the number-of-films display portion for displaying the number of filmed images may be configured to display the number of self-imaged images instead of the number of filmed images only during the self mode. Since they are also used, there is an effect that the number of display components does not increase and the cost is reduced.
