ABSTRACT:
A color correction unit for natural images, graphics and characters performs color correction of enlarging regions corresponding to primary colors (R (red), G (green) and B (blue)) and secondary colors (C, M and Y) while maintaining gray balance for R0, G0 and B0 raster image data representing an input object image, to generate C1, M1, Y1 and K1 multivalue density data. A binary-coding processing unit performs binary-coding processing of the C1, M1, Y1 and K1 multivalue density data to generate C2, M2, Y2 and K2 binary density data, and transfers the generated density data to a printer using a centroparallel interface or the like.
