Abstract:
A picture signal processing device having a plurality of element processors and a controller for performing common control of said element processors, said element processors being arrayed in association with pixels arrayed in a one-dimensional direction of a digitized two-dimensional picture, said pixels arrayed in the one-dimensional direction being chronologically sequentially entered to said element processors, each of said element processors comprising:a local memory for transiently storing pixel data of luminance and chroma;an input register for storing the input pixel data of luminance and chroma for transfer to said transient memory;at least one skip pixel register for storing pixel skip information for skipping pixels of luminance and chroma;an arithmetic-logic unit for carrying out pre-set calculations using the input pixel data of luminance and chroma or pixel data of luminance and chroma of nearby element processors based on pixel attribute information supplied to said arithmetic-logic unit, the pixel attribute information representing at least an attribute of luminance pixels; andan output register for storing and outputting the pixel data of luminance and chroma taken out from said local memory.
