PURPOSE:To improve picture quality by recognizing the original state for every color for image data and performing different space filter processings and correction processings for every color to eliminate the generation of a blotting and the void. CONSTITUTION:An image reading part reading image data converts image data into RGB image data and outputs it to an image processing part 102. The original recognition part 202 of the image processing part 102 recognizes the original state for every color according to inputted RGB image data and outputs image data to YMCBK changing the processing of each block. A RGB filter 203 where YMCB image data is inputted selects each processing of a smoothing processing and a sharpening processing, etc., and executes by a space filter by corresponding RBG image data to inputted data. Thus, at the time of an image formation, the blotting by the filter processing enforced for every color is eliminated, the voide by the erase processing except a black color is eliminated and image quality is improved. |
