Abstract
The present invention discloses a color calibrating method for setting target gamma curves of a target display device by utilizing operations of color space transformation and chromaticity coordinate value comparison according to color characteristics of a reference display device. The color calibrating method disclosed by the present invention is able to measure only various gray levels of white frames, and utilize transformations between the different color spaces and comparison operation of the chromaticity coordinate value setting the target gamma curves of R, G, B for the target display device according to the color characteristics of the reference display device so as to make the color characteristics of the target display device be substantially equal to the color characteristics of the reference display device. Thus, the color calibrating method of the present invention can efficiently reduce required measuring data and time of calibrating the color characteristics of the target display device.
