ABSTRACT:
A picture processing apparatus inputs window data (W) to look-up tables (TBL) in which operators (G or F) to be applied to pixel data (x) are stored in correlation to the locations of the pixel data. By switching between the operators (G or F) contained in the look-up tables (TBL), window processing corresponding to a data address (i,j) is performed on input pixel data (x.sub.ij).
