PICTURE SIGNAL PROCESSING APPARATUS

A picture signal processing device for performing picture signal processing such as conversion of the number of pixels or conversion processing for the number of scanning lines. The picture signal processing device includes a plurality of element processors and a controller for performing common control of said element processors. The element processors arrayed in association with pixels arrayed in one-dimensional direction of a digitized two-dimensional picture. The pixels arrayed in one-dimensional direction are chronologically sequentially entered to the element processors. Each element processor includes a transient memory for transiently storing pixel data, an input pixel data memory for storing input pixel data for transfer to the transient memory, a pixel attribute information memory for storing the pixel attribute information representing the attribute of pixels, a pixel skip information memory for storing the pixel skip information for skipping pixel data, an arithmetic-logic device for carrying out pre-set calculations using the input pixel data or pixel data of near-by element processors based on the pixel attribute information, and an output pixel data memory for storing and outputting the pixel data taken out from the transient memory. The picture signal processing device can cope with conversion processing at an optional ratio.
