Abstract
The contrast sensitivity function for human vision is well understood. It is known that the contrast sensitivity of luminance discrimination shows a band pass profile and that of chromatic discrimination shows a low pass profile. This characteristics of human vision is applied to the NTSC television transmission system. The image on color TV is formed by the basis of additive mixture of three primary colors; red, green and blue. When we estimate the image quality of color TV, therefore, it becomes very important to know the spatial frequency characteristics of each primary color for human vision.
