Abstract
A color calibration system in accordance with a preferred embodiment of the present invention comprises a display device provided with a color sensor for detecting a color temperature and illuminance of ambient light, a microcomputer, and a colorimeter for performing colorimetry on a display screen of the display device from the outside. The microcomputer calculates a target value by using a preset calculation equation and a detection result on the ambient light detected by the color sensor. Then, the microcomputer automatically performs color calibration of the display device so that a colorimetry result obtained by the colorimeter may agree with the target value.
