    Abstract: This invention provides a system and method for image signal contrast extension and overflow compensation. The system includes contrast extension and overflow compensation look-up tables, an image gray level boundary determining unit, a contrast extension unit, an overflow judging unit, and an overflow compensation unit. The image gray level boundary determining unit defines a maximum and a minimum among the gray levels of the pixels of an image signal and calculates the difference. The contrast extension unit selects corresponding parameter from the contrast extension table for contrast extension of a given image pixel. The overflow judging unit judges whether the pixels are overflowed. The overflow compensation unit compensates the pixel. When a pixel is overflowed, the overflow compensation unit selects, according to the gray level of the pixel, a corresponding overflow compensation parameter to reduce the gray level to overcome the problem of overflow.

  • Patent number: 7692607
    Abstract: A method for adjusting an image on the basis of characteristics of a display system is provided. The image includes M horizontal lines. Each of the M horizontal lines respectively includes N pixels. Each pixel has an original gray level. A look-up table previously stores a plurality of conversion coefficients related to the characteristics of the display system. The method first calculates an ith loading according to the N original gray levels of the N pixels in the ith horizontal line. Based on the ith loading, an ith conversion coefficient corresponding to the ith loading is selected from the plurality of conversion coefficients in the look-up table. The method respectively multiplies the N original gray levels of the N pixels in the ith horizontal line by the ith conversion coefficient to generate N new gray levels for the N pixels in the ith horizontal line, whereby the image is adjusted.
