ABSTRACT:
A camera, which uses a film cartridge having a film exposure status display, comprises an E2PROM. The E2PROM stores the fact that the film status determination operation is underway when film status determination operation is underway. When a power supply is removed while the film status determination is operating and then the power supply is mounted, the camera operates an initial process. The film exposure status display is set in `exposed` because the E2PROM holds that the film status determination operation is underway. A camera is .provided that deems the film in the film cartridge to have been exposed and does not perform exposure if the power supply is cut off while the determination of the film status of the film in the film cartridge mounted in the camera is underway.
