  • 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.

  • Patent number: 7447357
    Abstract: A method for adjusting an input image on the basis of the characteristics of a display system is provided. The input image includes N color elements and the display system is capable of displaying P second gray levels. P sets of first conversion coefficients related to the characteristics of the display system are beforehand stored in a look-up table. The method according to this invention first calculates an estimated gray level according to the input image and a set of predetermined second conversion coefficients. Then, a set of third conversion coefficients corresponding to the estimated gray level is selected from the look-up table. A final gray level is calculated on the basis of the set of third conversion coefficients. Finally, the final gray level and the N color components are combined into an adjusted image to replace the input image, whereby the input image is adjusted.
