ABSTRACT:
A multicolor printer which can print an image with improved image quality by selecting a desired color reproduction process depending on data to be handled. An output apparatus comprises an input unit 111 for receiving visual data containing data in a command format for output control; image data etc. delivered from an external apparatus; an analyzer 112 for analyzing the input data; a developing unit 113 for developing the input data into output data based on an analyzed result; a color processor 114 for executing color processing such as color space compression on the input data during the development by the developing unit; a color processing method storage 116 for storing a plurality of color processing methods executed by the color processor 114; and a selector 115 for selecting one of the plural color processing methods in the storage 116. When developing the input data by the developing unit 113 into the output data, desired one of the plural color processing methods is selectively used in the output apparatus depending on the input visual data. Thus, optimum color reproduction depending on any of plural types of input data attributes is enabled without increasing load on a host computer.
