<P>PROBLEM TO BE SOLVED: To provide a method to adjust an inputted image based on the characteristics of a display system. <P>SOLUTION: The inputted image has N color components and the display system can display a second gray level of P gradation. First conversion coefficients of P sets related to the characteristics of the display system are beforehand stored in a lookup table. In this invention, an estimated gray level is computed at first in accordance with the inputted image and a set of beforehand determined second conversion coefficients. Then, a set of third conversion coefficients corresponding to the estimated gray level are selected from the lookup table. Then, the last gray level is computed based on the one set of the third conversion coefficients. Lastly, the last gray level and the N color components are combined to produce an adjusted image and the inputted image is replaced by the adjusted image to adjust the inputted image. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
