Abstract
A microcomputer (.mu.COM) in a camera causes an EEPROM in a memory unit to store data on each picture taken. The photographic data stored in the EEPROM is read by the .mu.COM and displayed on a display unit. According to the operation of an UP SW or a DOWN SW, the .mu.COM updates the contents stored in the EEPROM now being displayed. The photographic data stored in the EEPROM is written in a first magnetic track on the film by a first magnetic head arranged in a magnetic information control circuit, at the time of the rewinding of the film. In addition, when a film with which photography is already finished is loaded in the camera, the .mu.COM, while advancing the film, causes the first magnetic head to reproduce the data written in the first magnetic track on the film and stores the reproduced data in the EEPROM.
