Abstract:
The present invention discloses a method of correcting screen brightness and color temperature, it relates to the field of display technology. The present invention is used for correcting the working parameters of the every m stages of gray-level pictures to adjust display of the screen to a maximum gray level, the correction is started from a gray level next to the maximum gray level, and only for correction of the first gray level, working parameters of the previous gray level are used as the initial values of working parameters of the current gray level correction; from correction of the second gray level, a correction estimated value of working parameters of a current gray level is estimated according to the working parameters and the local linearity relation of the two corrected gray levels, and the correction estimated value is taken as the initial working parameter of the current gray level correction. The method has the advantages that the method has higher reliability, thereby being capable of effectively correcting different screens or screens nonuniform in quality, and the method has higher accuracy and speed, thereby being capable of completing correction in fewer number of times of adjusting.
