ABSTRACT:
A camera comprises an exposure frame for defining an exposure aperture in the camera body, an automatic film winding device incorporated in the camera body, and a light emitting element disposed at the exposure frame. The light emitting element is controlled to emit light to which a loaded film is exposed as the film is advanced by the automatic film winding device. The film provided by the camera, after development, shows a visible image of various line marks produced by the light emitting element which indicate that the film or a portion of frames on the film have been exposed under a certain mode of operation of the camera. The line mark is detected when picture images on the film are magnetically recorded on a magnetic sheet. The magnetic sheet is transferred to a reproducing apparatus in order to display the picture image on a TV screen in one of a variety of ways according to the line marks.
