ABSTRACT:
A camera records information relating to each photographic frame of a film onto an information recording area provided on the film while the film is being fed. Regulating circuitry is provided to regulate the recordation so that no information is recorded for a frame under consideration when it is confirmed that the information relating to the frame under consideration is the same as information relating to a previous frame. In all other cases information relating to a frame under consideration is recorded for the frame under consideration. This greatly decreases the amount of information recorded when the same information continues for multiple frames and prevents wasteful expenditure of a battery power source.
