摘要： 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.

摘要： A dynamic color temperature and color deviation calibration method is provided for eliminating problems associated with color temperature change and color deviation caused by an emissivity change of red, green and blue phosphor layers of a plasma display panel (PDP). The method comprises the steps of utilizing laws of color matching for calculating an emissivity change of a pixel of the PDP in response to a brightness change of one of red, green, and blue lights emitted by a corresponding one of red, green and blue discharge cells of the PDP through a numeric operation; dynamically adjusting brightness of one of the emitted red, green, and blue lights by increasing or decreasing strength of input video signal of each of the discharge cells; and eliminating a color temperature and a color deviation of the PDP due to an emissivity change. This can render an image having an optimum color purity and color temperature by eliminating adverse effects on PDP due to emissivity change.

摘要： 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.
