Abstract
A system for simultaneous recording of a flash image on photographic film and video cameras in which flash operation during the process of image transfer out of an image sensor in the video camera is avoided by means of a simple synchronizing circuit. The synchronizing circuit operates in response to a flash request signal from the film camera to interrupt the transfer of image information out of the image sensor in the video camera for at least the duration of the flash illumination on the subject. Following conclusion of the flash illumination, the synchronizing circuit resets the image sensor processing circuits to restart transfer of the image information out of the image sensor at the beginning of an image field. The restart can coincide with conclusion of the flash illumination or can be delayed to coincide with a desired video frame in the composite video signal.
