A graphics controller 114 generates a video signal for forming a display image to be displayed on the display device. A high quality video engine 115 performs a high quality video process on the video signal generated by the graphics controller 114. When a user performs a luminance change operation for changing the luminance of a light in the LCD 17, 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 115 are changed through an application, an intermediate module, a BIOS, and an EC/KBC 124.
