One of the factors deteriorating the image quality of PDP-TV is the low gray-level contour occurring mainly due to inverse gamma correction. From the viewpoint of human visual perception, the low gray-level contour becomes more serious because of the nonlinear output luminance of PDP at low gray-levels. In this paper, a modified inverse gamma correction method and a gray-level linearization technique considering human visual perception are proposed for enhancing image quality at low gray-levels.
