摘要：
A video processing system is described for providing an image having more than one region on a display (DISPLAY). The system has a control means (1110; 110) which can determine, for each region (501, 502; 510, 520, 530), the type (e.g., graphics, text, computer programs, broadcast TV video, etc.) of the image material being displayed in the region (501, 502; 510, 520, 530). The system also has a video driver (1155; 135) coupled to the display for providing image signals having contrast and brightness characteristics. The control means (1155; 135) generates a control signal for causing said video driver means to adjust said contrast and brightness characteristics of said image signals according to the type of material being displayed in said region.
