ABSTRACT:
An image processing system that shorten calibration time includes a storage section which stores darkroom-condition-measurement data obtained by measuring a display region on which a plurality of calibration images having different colors are displayed under a darkroom condition through a sensor; a measurement data generating section which generates supposed measurement data based on a viewing-environment-measurement data obtained by measuring one of the plurality of calibration images through the sensor under a viewing environment and the darkroom-condition-measurement data; a color gamut computing section which computes an area ratio between a color gamut based on the darkroom-condition-measurement data and a color gamut based on the supposed measurement data; and a correcting section which corrects an image correcting data to correct a hue and gray scale of an image using a logistic function with a parameter based on the area ratio and also corrects image information for displaying an image.
