【Abstract】 Using the latest development of gamma correction in color TV as a background, this paper introduces three types of TV display modeling and, considering the disadvantages of the conventional gamma correction circuit, the paper puts forward a new algorithm to improve it and makes a good compromise between hardware budget and precision control. The results show that this algorithm can greatly reduce the area of the IC chip and save the power without any deterioration in the quality of the image.更多还原
