摘要: A video signal processing circuit is provided to display an image of a standard television on unit with 16:9 aspect ratio by enlarging in the horizontal and vertical directions magnification factor which depends feature signal. The includes first memory (104) reads out stored response read clock different from write generated stable frequency source so that expanded direction, second (105) implements time-base compression for output thereafter expands signal, spatial filter (106) filtering circuit, enlargement control (107) above-mentioned circuits, synchronizing (108). arrangement enables signals various sizes, such as movie pictures, be displayed conversion ratio, capable suppressing jitters signals.
