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.
