Abstract
Charges are read out from a CCD n (where n is an integer or greater) times within 1 field period, under the control of a controller. Under the control of a memory controller, a VTR records the n images as a video signal for 1 field, based on the readout charges. When playing back, under control of the memory controller, the video signal for 1 field, which is read out from the VTR and which includes n images, is temporarily stored in a memory. The memory controller reads out the n images from the memory in time sequence, and displays each image on a display m (where m is an integer 1 or greater) times during period of m fields, thereby performing slow playback at a playback speed of 1/(n.times.m). Along with a video signal for each field, the VTR records information with regard to the number n of the images and the display positions thereof.
