发明名称 Color image processing apparatus
摘要 An image processing apparatus converts n-level image data into m-level image data, where n<m. Types of multivalue processing applied to a main color component and types to sub color components are different, and data thereby obtained are multiplied by predetermined coefficients, then the results of these calculations are added together to obtain data on each color component, thereby enabling an improvement in image quality.
