发明名称 IMAGE PROCESSING METHOD AND IMAGE PROCESSOR
摘要 PROBLEM TO BE SOLVED: To provide an image processing method and an image processor which can perform contrast correction corresponding to a color bias in the case of processing a multi-level image of a plurality of colors. SOLUTION: The features of an image luminance frequency distribution for every color are compared to judge, whether or not a color bias exists (S204). When the existence of color bias is judged in the judgement process, contrast correction is performed on the basis of the mutual relation of the luminance frequency distributions of respective colors (S206).
