ABSTRACT:
A video printer for making a print of main frames of different scenes of a video motion picture or animation recorded on a video tape, video floppy or the like can detect automatically one frame for each scene. For detecting a scene transition, the video printer is provided with a frame comparing device for comparing video signals of every pair of two adjacent frames reproduced time serially to provide a signal representative of the degree of correlation thereof. A judging device determines that there is a scene transition when the frame comparing device provides a signal larger than a preset signal. The video printer makes a print of a first frame reproduced after a lapse of a predetermined time period after the detection of the transition of scene. The main frames of the different scenes are printed as a composite image to provide an index print for demonstrating the contents of a video tape.
