Abstract
A central processing unit (CPU) is reset during the removal of a battery or the voltage drop, while, in an electrically erasable/programmable read-only memory (EEPROM), there is stored and held information of the camera operation immediately before the reset and the number of film frames. Then, when the CPU becomes operable by the exchange of batteries and the like, the information of camera operation immediately before the reset and the number of film frames are read out from the EEPROM during the processing at the initial stage thereafter, the operations corresponding to the information of camera operation is continued and the number of film frames thus read out is changed by one and set as the film count value when the information of camera operation indicates one frame delivery. With this arrangement, the interrupted frame delivery is also counted as one frame, so that the final frame is prevented from entering a photographing preventing region of a film.
