ABSTRACT:
In an electronic still camera, a mechanical shutter is opened in synchronizing with a synchronizing signal generated by a synchronizing signal generating circuit, a solid state electronic imaging device is exposed while the mechanical shutter is being opened, and a video signal outputted from the imaging device and representing an imaged subject is processed by a signal processing circuit. The synchronizing signal generating circuit starts the generation of the synchronizing signal in response to a shutter release by a shutter release button. The mechanical shutter is opened in synchronizing with a synchronizing signal which is generated after a predetermined constant time period elapses from the start of the operation of the synchronizing signal generating circuit, and is closed after time necessary for exposure elapses from the opening of the mechanical shutter.
