ABSTRACT:
A graphics controller generates a video signal for forming a display image to be displayed on the display device. A high quality video engine performs a high quality video process on the video signal generated by the graphics controller. When a user performs a luminance change operation for changing the luminance of a light in the display LCD, values of various parameters (such as contrast, brightness, hue, saturation, gamma correction value, etc.) to be used in the high quality video process of the high quality video engine are changed through an application, an intermediate module, a BIOS, and an embedded controller/keyboard controller.
