摘要
A shading compensation device which compensates for shading which differs for respective colors. A pixel counter counts co-ordinate positions of image data which is supplied from a black level correction section. A relative position calculation section compares the image data with compensation value tables and calculates relative co-ordinate positions of pixels which are objects of processing. A compensation value interpolation section refers to the compensation value tables, which are stored for the respective colors in a compensation value table memory, and interpolates shading compensation values for the relative co-ordinate positions calculated by the relative position calculation section. A multiplier multiplies the image data which is the objects of processing with the new shading compensation values obtained by the interpolation processing. Thus, shading-compensated image data is generated.
