Abstract
Image information which represents an object image and includes a logical operation table is input to a color convertor which converts the input image information into color image data including a black density component and a plurality of color density components. A data convertor converts the color image data into a linearly independent color image data by converting the blank density component into a plurality of color density components. A logical operator performs a logical operation on a plurality of color component data forming the linearly independent color image data on the basis of the logical operation table.
