Electronic camera operable in a dual shoot mode together with a camera with a film

摘要

An electronic camera system includes a shutter controller for sending a drive signal to the shutter of a camera loaded with a silver halide sensitive type of film. The drive signal is synchronous to a release signal generated when a release button is pressed, and causes the shutter of the camera with the film to open. The release signal is also applied to a dual shoot controller included in the electronic camera. In response, the dual shoot controller feeds release signals to a synchronizing signal generator and a system controller. In response, the synchronizing signal generator delivers to a solid-state imaging device a drive signal synchronous to the release signal fed to the synchronizing signal generator, without regard to the output signal of a reference oscillator. As a result, an electronic shutter included in the imaging device is opened, and charge is stored in the imaging device. In response to the release signal, the system controller immediately feeds a shoot start command to the various sections of the electronic camera.
