Abstract
A video signal processing apparatus is arranged to input a video signal in which one frame is composed of a plurality of fields and scanning lines are interlaced among the plurality of fields, selectively take a mode for sequentially outputting video signals of a plurality of fields of a frame and a mode for consecutively outputting a video signal of one of the plurality of fields by a plurality of times, and output the video signal thus processed to a display device having displayable scanning lines the number of which is smaller than the number of scanning lines per field of the input video signal. With the above-described arrangement, even if a video signal in which scanning lines are interlaced is supplied to a display device having a comparatively small number of displayable scanning lines, it is possible to obtain a display image free from a vertical image shake.
