摘要： A gamma correction method is disclosed that performs gamma correction for a display device. A plurality of correction matrices respectively corresponding to a plurality of spectrums of different test display devices is obtained. A spectrum of the display device is measured. A correction matrix corresponding to the spectrum of the display device is selected from the plurality of correction matrices. Tristimulus data of the display device are measured and the measured tristimulus data are converted into perception tristimulus data by using the selected correction matrix. The gamma correction for the display device is performed based on the perception tristimulus data.
