<P>PROBLEM TO BE SOLVED: To enhance the detection accuracy of a density value in the density calibration of a printer. <P>SOLUTION: The density value is detected by changing over the gain of a detection means so as to enhance the resolving power for detecting the density value of an A/D conversion means in predetermined timing (at a feed position of an image to be printed or a recording material) to perform the correction treatment of image data. <P>COPYRIGHT: (C)2004,JPO |
