Abstract
An apparatus for processing a video signal comprises receiving units for receiving video signals, filter units for repeating filtering processing in two or more times of generating a new pixel at a position at which adjacent pixels of the received video signal are mutually weighted by a ratio of roughly 3:1 and generating a new pixel at a position at which precedingly generated adjacent pixels are mutually weighted by a ratio of roughly 3:1, and selection units for respectively selecting a pixel to be extracted among pixels to be performed filtering processing in two or more times on the basis of a scaling ratio to discriminate a position of a pixel to be output.
