A video processing method for selectively processing character information (Ic) included in an inputted video stream (Svc). The video stream (Svc) is separated in units of frame into a brightness frame (Y) representing brightness information (VY) and a plurality of color difference frames (Cb, Cr) representing color difference information (VCb, VCr). Character information (Ic) included according to at least either of the brightness information (VY) and the color difference information (VCb, VCr) is recognized. The recognized character information (Ic) is subjected to a processing by at least one of deletion, movement, and enlargement.
