摘　　要：A psychophysical experiment is performed on two large-size liquid crystal displays under three viewing conditions to assess perceptual contrast. Based on the visual data, the performance of CIECAM02 in pre- dicting perceptual contrast under different viewing conditions is tested and compared with other models by F-test, Results show that the perceptual contrast models in the form of Weber contrast using CIECAM02 brightness Q agreed better with the contrast perception of human visual system compared to the models using luminance, CIELAB lightness L＊, and CIECAM02 liehtness J.A psychophysical experiment is performed on two large-size liquid crystal displays under three viewing conditions to assess perceptual contrast.
