Abstract

The invention provides a color calibration system capable of performing color calibration with high accuracy and simply. The color calibration system (100) in accordance with a preferred embodiment of the present invention comprises a display device (12) provided with a color sensor (12c) for detecting a color temperature and illuminance of ambient light (14), a microcomputer (12b), and a colorimeter (13) for performing colorimetry on a display screen (12a) of the display device (12) from the outside. The microcomputer (12b) calculates a target value by using a preset calculation equation and a detection result on the ambient light (14) detected by the color sensor(12c). Then, the microcomputer (12b) automatically performs color calibration of the display device so that a colorimetry result obtained by the colorimeter (13) may agree with the target value.

Description

technical field [0001] The present invention relates to a color calibration system of a display device. Background technique [0002] Conventionally, color calibration of display devices has been performed using a colorimeter for the purpose of color matching in a visual environment. In the existing color calibration system, the preset white point (brightness / chromaticity) or the user's desired white point is used as the target value, and the user performs the adjustment operation by himself. In the case of this color calibration system, the user needs to obtain beforehand the integration with various conditions that cannot be independently managed by the display, such as the color temperature of lighting in the viewing environment, the illuminance, or the color of paper. [0003] In addition, the shape of the spectral distribution of the observed light is greatly different between the illumination light and the display of the display device. Therefore, even if a dedicated...
