发明名称 Image processing system for processing achromatic color image data
摘要 An image processing system for executing a color process on color image data and generating output color image data composed of a plurality of color component data including black component data, the system using a mode for generating the output color image data such that, when input color image data is an achromatic color, color component data other than black component data in the output color image data are substantially zero-valued. The system includes setting, based on an instruction from a user, relationships between a plurality of types of object images and the mode, inputting object image data of an input image, discriminating the type of the object image data, and executing the color process on color image data of the object image data using the mode based on the setting step and the type discriminated in the discriminating step.
