摘要： 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.

摘要： The present invention relates to the exposure compensation information forming apparatus for a camera, particularly for forming the aperture and the totally opened aperture value information. Until now in order to compensate the totally opened aperture value contained in the output of the light measuring circuit and the aperture value the information setting means for the totally opened aperture value and that for the aperture value are provided, whereby both setting means are mechanically engaged with each other so as to form the totally opened aperture and the aperture information. Thus, the engaging mechanism of both of the above means is complicated, which is inconvenient. The present invention provides an exposure compensation information forming apparatus by means of which the aperture information can be composed from the totally opened aperture with a very simple circuit composition so as to overcome the above disadvantage.
