Abstract
A camera having a sound recording function is disclosed, in which an object image is photographed/recorded, as an optical image transmitted through a photographic optical system or photoelectrically converted image data, on a film having a magnetic recording portion, a magnetic disk/tape, or the like, while sound data is sampled for a predetermined period of time before/after the photographic operation. The sampled sound data is temporarily stored in a sound data storage section constituted by a semiconductor memory and the like. In a film wind-up operation, the sound data is written in the magnetic recording portion of the film. With this operation, the predetermined number of frames can be photographed regardless of whether sound data is present or absent. Further, another camera having a sound recording function is disclosed, in which sound around the camera (sound data) at a given time is temporarily stored in a sound data storage section 54, and sound stored during a film wind-up (film advance) operation is stored on a magnetic track of a film.
