ABSTRACT:
A video signal from an input unit is supplied to first and second low-pass filters. A selector picks up a video signal which has passed through the first low-pass filter if a single frame image is to be printed, and picks up a video signal which has passed through the second low-pass filter if a multifreeze image is to be printed. The picked-up video signal is sampled and quantized by an A/D converter and stored in a first memory. The video signal in the first memory is read out to print a signal frame image. To print a multifreeze image, the video signal stored in the first memory is thinned to reduce the size of an image and thereafter is stored in a second memory having a larger capacity than that of the first memory. A plurality of frames are inlaid within one frame at the second memory. Thereafter, the video signal in the second memory is read out to print a multifreeze image.
