Abstract

Combined with color rendering characteristic of the cathode ray tube display,the experiment scheme in which the display shows target grating to measure red-green and blue-yellow color contrast sensitivity was designed.11 observers were measured to obtain the characteristic data of color contrast sensitivity for human visual system,and the data were fitted.According to the experience of the former and theoretic analysis,the CSF mathematics model to reflect human color vision characteristics was put forward,and the results were compared with foreign ones.The results show that the CSF model based on the display measurement,fitting and theoretic analysis can better reflect the human visual system characteristics.The CSF model is a scientific mathematical model reflecting human visual system characteristic.
