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.

Abstract: A camera has a recording apparatus for magnetically recording finished photograph information, indicating exposure of a film frame, and for magnetically recording other photograph information for each film frame. The finished photograph information is recorded at a designated film area, while a film feed motor is in a transient speed state. Other photograph information is recorded in a designated film area when the film feed motor speed is constant. Appropriate positioning of the designated recording areas for recording information therein is determined by counting film perforations or by measuring a period of time during film feed subsequent to an exposure.

Abstract: An information processing device, such as a camera, capable of magnetically recording information on film, controls magnetic recording and film feeding using a single position detector that detects film position information, such as perforations in the film. After a frame of the film has been photographically exposed, the information processing device first feeds the film in a reverse direction opposite to the direction of advancement, before accelerating the film forward in the advancement direction to a stable advancement velocity. The usable length of the magnetic recording area of the film is thus increased because recording does not take place while film velocity is changing.
