Abstract
The imaging of a scene by two cameras is synchronized, wherein both cameras include releasable shutters exhibiting different shutter release delays. A controller responds to a release start signal to release the shutter of one of the cameras at a first time and to release the shutter of the other camera at a second, delayed time, the delay being substantially equal to the difference between the shutter release delays of the cameras. The release start signal may be manually produced when the user actuates a start switch; and this start signal is synchronized, or re-timed, when a predetermined one of the cameras is conditioned to image the scene. For example, if that camera includes a rotatable record disk to store electronic image signals, the shutter release operation is synchronized with the rotation of the disk to a reference position.
