ABSTRACT:
Video signals are recorded in such a manner that prints having a high picture quality can be obtained while not interfering with playback of images in the form of a movie. A CCD is controlled in such a manner that exposure is performed at a shutter speed of 1/250 of a second one time in exposures performed a plurality of times in succession and at a shutter speed of 1/60 of a second at other times. The video signal outputted by the CCD is applied to a combining circuit via a CDS, AGC and signal processing circuit for an image sensing system. A PI signal generating circuit outputs a PI signal, which represents inhibition of printing, in the case where exposure is carried out at the shutter speed of 1/60 of a second, and the combining circuit superposes the PI signal upon the video signal, which has been obtained by exposure at the shutter speed of 1/60 of a second, in the vertical blanking interval of this video signal. The output of the combining circuit is applied to a recording playback head via a signal processing circuit for a recording system, whereby the output is recorded on a video tape.
