Patent ID: 7170535

Claim:
An image processing system comprising: a display means for displaying a predetermined calibration image; a sensing means for sensing the displayed calibration image; an area detection means for detecting an image display area based on sensing information obtained by the sensing means, and also dividing the image display area into a plurality of target areas; a brightness information generation means for generating brightness information which indicates an average brightness index value within each of the target areas that have been divided by the area detection means, based on the sensing information; a correction amount calculation means for calculating a correction amount for input-output characteristic data from each of the target areas, based on the brightness information; and a color non-uniformity correction means for correcting color non-uniformity of the image in each of the target areas, based on input-output characteristic data that has been corrected based on the correction amount, wherein the display means displays an image in which color non-uniformity has been corrected by the color non-uniformity correction means.
