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.

DETAILED DESCRIPTION An object of the present invention is to solve all or some of the drawbacks mentioned above.
Another object of the present invention is to provide a color image processing apparatus, a color image processing method and a color image output apparatus, which can satisfactorily reproduce a natural image or the like.
Still another object of the present invention is to provide a color image processing apparatus, a color image processing method and a color image output apparatus, which enables precise color reproduction for an CG image or the like.
To achieve the above objects, according to a preferred embodiment of the present invention, there is disclosed an apparatus comprising input means for receiving visual data from an external apparatus, analyzing means for analyzing the input data received by the input means, data developing means for developing the input data into output data in accordance with a result analyzed by the analyzing means, and including color processing means which executes color processing on the input data, storage means for storing a plurality of color processing methods to be executed by the color processing means in the data developing means, select means for selecting one of the plural color processing methods stored in the storage means, and output means for outputting the data having been developed by the developing means to be adapted for output.
Yet another object of the present invention is to provide a color image processing apparatus which is suitably built in apparatus having a printing function.
Further objects, features and advantages of the present invention will be apparent from the following detailed description of embodiments of the present invention with reference to the accompanying drawings.
