    • An image pickup apparatus using an image sensor is provided with a rotary shutter that controls the amount of time the image-forming light strikes the image sensor. A synchronism detector is provided to detect the phase difference between the rotation of the rotary shutter and the scanning of the image sensor by comparing the phase signals produced according to the speed of rotation of the rotary shutter and vertical synchronizing signals periodically produced as well as scanning signals for scanning the image sensor. When there is no phase difference between the two signals, the synchronism detector provides an operation signal which causes a switching circuit to be conductive, so as to permit an image recorder to record images. On the other hand, if there is a phase difference, the synchronism detector provides no operation signal and the switching circuit is rendered non-conductive so as to prevent the image recorder from recording images.
