FRAME-SHIFTED DYNAMIC GAMMA CORRECTION METHOD AND ITS SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a dynamic gamma correction method and its system which is simple and quickly operates and reduces the amount of utilization of a buffer. SOLUTION: Statistics of gray levels are taken for one frame 20 to generate one statistical data, a set of gamma reference voltages is determined based on the statistical data and the gamma voltages of a next frame 22 are corrected by the gamma reference voltages including the input to the next one frame 22. One counter 32 is used to take statistics of the gray levels of the one frame 20 to generate one statistical data. One gamma reference voltage determiner 34 determines a set of gamma reference voltages from the statistical data and gamma voltages of the next frame 22 are corrected. One detector 36 detects the input to the next one frame 22. COPYRIGHT: (C)2005,JPO&NCIPI
