Abstract
A video signal processing apparatus which performs a frame-rate conversion of a progressive line-scan video signal based on a film source of M film frames per second (wherein M is a natural number) into a video signal in which a same film frame is repeated N times for each 1/M second, and mixes, frame by frame, a video signal of a preceding frame and a video signal of a following frame of the converted progressive line-scan video signal. Thus, the display quality of telecine-converted images can be improved.
