ABSTRACT:
A pattern generator generates a color chart which is processed by an image processor and reproduced on a medium by an output device without color correction. Since no color correction is made to the color chart on the medium, the image processing characteristics of the image processor and the output device are reflected in color chart on the medium. The color chart on the medium is read by a reader and converted to color chart read data which is converted to color correction parameters for the output device by a color correction parameter generator. The color correction parameters are stored in a first storage device, and device setting values indicative of characteristics of the output device are stored in a second storage device. When another color image is read by the reader or input by another input device, a color corrector color corrects the color image based on the color correction parameters stored in the first storage device, with the color corrected image then being processed by the image processor, the operational characteristics of which are adjusted in accordance with an operator selected setting value stored in the second storage device. The color corrected and processed image is the output by the output device.
