Abstract
Input data corresponding to three primary colors C, M and Y are subjected to masking correction, to obtain data C', M' and Y'. A correction factor in a masking equation is varied depending on which of three sections into which all the gray levels of each of the input data C, M and Y are divided, the section being a section to which the input data of a selected color belong. As a result, suitable masking correction conforming to the value of the input data is made, thereby to improve color reproducibility of a color image.
