摘要： The invention discloses a color correction method for adjusting the color performance of a display apparatus. The color correction method first displays a plurality of images on a panel of the display apparatus and measures the chromatic value and the luminance of each image so as to obtain the color characteristics of the display apparatus. According to the color characteristics, a corresponding color matrix is generated which is located at the CIE XYZ color space. Next, an output matrix is outputted by performing an operation between the color matrix and a gain matrix. Next, the elements in gain matrix are adjusted in order to have the output matrix be equal to a target matrix substantially. Finally, the display apparatus is set for calibrating the color performance thereof in accordance with the elements of the adjusted gain matrix.
