    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 adjusting apparatus for enhancing the contrast of an image and a method therefor are provided. The adjusting apparatus includes a mask processor, a brightness detecting unit, a brightness adjusting unit, a ratio calculating unit and a contrast enhancing unit. The mask processor retrieves a pixel matrix from an original image according to its mask dimension, and outputs a specific pixel corresponding to a specific position in the pixel matrix. Then, the brightness detecting unit, the brightness adjusting unit and the ratio calculating unit are coupled in series to process the image according to relations of each sub-pixel of the pixel matrix, so as to obtain an adjusting ratio. Thereby, the contrast enhancing unit multiplies the value of the adjusted specific pixel by the adjusting ratio to enhance the contrast of the image.
