Abstract
The consumer electronics with display becomes more and more important in life. Recent day, the liquid crystal display（LCD）has been one of technological research topic focusing on increasing size or enhancing resolution. Therefore, people focus on image quality and vivid color on the display. Hardware material and digital signal processing are two major parts of the direction of the LCD research.his thesis proposes digital signal processing which is application to enhance the quality of video display. Two main techniques are proposed in this thesis: To improve the chrominance and luminance of video frames on CIEL*a*b* color space. One, contrast enhancement method makes images bright and clear. Second, saturation enhancement method makes colors vivid and pleasant. Beside, the CIEL*a*b* color space separating chrominance and luminance is the widest color space nowadays.inally, the experiment of these two methods are implemented successfully on FPGA board and LCD monitor. The FPGA board that are used limited hardware area can be applied to dynamic video.
