ABSTRACT:
A camera includes a display that displays in the viewfinder a photographic screen size even when the low consumption power supply mode is in use. The camera includes a power source, a controller, a film winding motor, a panorama frame driving motor, a CPU, an EEPROM, a viewfinder LCD and a timer. When the power switch is turned on, the CPU causes the panorama frame to move and changes the transmissivity of the viewfinder LCD to match the photographic screen size selected the largest number of times. When a new photographic screen size is selected using the photographic screen size switch, the number of times the photographic screen size has been selected is calculated and stored in the EEPROM. In addition, the time that has elapsed after the power switch has been turned on is measured by the timer, and when the time exceeds a predetermined value, the camera moves into the low consumption power supply mode with power still being supplied to the viewfinder LCD.
