摘要： A backlight processing system and a method thereof are provided. The gray level values of pixels in an input frame signal are adjusted and the brightness thereof is decreased correspondingly. During gray level value adjustment, the gray level values of the pixels in dark regions are reduced, and the gray level values of the pixels in bright regions are increased. During backlight adjustment, first, statistics information on distribution of the gray level value versus the number of pixels is obtained according to the gray level distribution of the original frame. The number of pixels at each gray level is accumulated. When the accumulation value reaches a certain value, a reference signal is obtained. The brightness of the backlight is then adjusted according to the reference signal.

摘要： Gray scale distribution of an input image signal is obtained through statistics to determine the contrast characteristic of the input image signal. Based on the gray scale distribution, by a look up table, corresponding gamma setting values are derived and stored in a register. The register outputs the stored gamma setting values to a gray scale voltage generation circuit to adjust the gray scale voltage. Therefore, the display contrast and display quality are improved.

The image processing method comprises the steps stated below. Firstly, a color purity of the pixel is calculated and a corresponding scale factor is generated according to the color purity, wherein the color purity is the difference between the maximum grayscale value and the minimum grayscale value of the data of the three colors. Then, a processed pixel data is generated according to an enhancement matrix and the pixel data, wherein the enhancement matrix is determined by the scale factor.

摘要： An image processing apparatus and an image processing method. The image processing apparatus includes a first convolution unit, a weight generator, a second convolution unit, an arithmetic unit and an outputting unit. The first convolution unit performs a convolution to output edge strength according to an original image signal and a high pass filter mask. The weight generator chooses a weight coefficient according to the edge strength. The second convolution unit performs a convolution to output an unsharp image signal according to the original image signal and a low pass filter mask. The arithmetic unit outputs a first sharpening signal according to the original image signal, the unsharp image signal and the weight coefficient. The outputting unit outputs a processed image signal according to the original image signal and the first sharpening signal.
