Abstract

A multiple exposure device for a camera is arranged to permit one and the same frame portion of film to be exposed to light a plurality of times. In taking a multi-exposed photograph, the device displays a multi-exposure mode; permits a manual resetting operation on the multi-exposure mode for improved operability of the camera; and computes the degree of exposure to be effected at each step of the multiple exposure to ensure an appositely exposed state of the film frame on which the multiple exposure operation is performed.
