ABSTRACT:
A blur-free printed image having a high vertical resolution is obtained from a signal obtained by photography using a movie video camera. Video signals of first and second fields are outputted by a CCD every 1/60 of a second. Ordinarily, these video signals are selected by a multiplexer in such a manner that the first and second fields are outputted alternately every 1/60 of a second. At a prescribed point in time, video signals of first and second fields obtained by simultaneous photography are outputted by the multiplexer. In this case a PI signal is added onto the video signals in a circuit for adding on synchronizing signals and the PI signal, and the resulting video signals are then recorded on a video tape. When the video signals are printed, the PI signal is detected and video signals of first and second fields obtained by simultaneous photography are recognized based upon the PI signal. The printed image is obtained from these video signals.
