Color Gamut and Contrast Enhancement for Mobile Phone Displays
2007 / IEEE / 1-4244-0783-4
This item was taken from the IEEE Conference ' Color Gamut and Contrast Enhancement for Mobile Phone Displays ' For modern mobile phone displays, their driving integrated circuit (IC) solutions, often called total solutions, have included various functions, such as scanning, driving, power-level conversion, image storage memory, timing control, and standard interfacing; however, most of them lack of real-time image processing engine. In this paper, a novel real-time pixel-level image processing algorithm is presented to enlarge image color gamut and enhance image contrast without frame memory for mobile phone displays. This image processing algorithm simultaneously executes two parallel algorithms: rich color and contrast enhancement. The rich color algorithm obtains a wide color gamut image data showing more than 30% area enhancement in the CIE1931 color space without hue distortion. The contrast enhancement algorithm improves 20% contrast ratio improvement. Numerous simulation results are provided to illustrate the feasibility and efficacy of the proposed algorithms and image processing engine. Experimental results are conducted to show the performance and usefulness of the proposed composite algorithm for 2.2-inch mobile phone TFT LCDs.
