  • Adjusting apparatus for enhancing the contrast of image and method therefor
    Patent number: 7916968
    Abstract: 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.
