Classification: CPC G | IPC G

Claim 2:
3. The automatic gamma adjustment system with environmental adaptability according to claim 2, wherein the display device uses an 8-bit, 13-bit, 16-bit or 24-bit grayscale image to display the image, and when grayscale levels are greater than 256 levels, the layering control processor uses the gamma control parameter to calculate and obtain the second YUV signals by an adaptive offset compensation to adjust and correct brightness value of 0˜8th grayscale layers, such that the brightness values of 0˜8th of the grayscale layers have no consecutive zero outputs; wherein, after the adaptive offset compensation counts total number of levels with the brightness value equal to 0 in 1st˜8th of the grayscale layers, reads minimum brightness value in 1st˜8th of the grayscale layers, and lists missing decimal integers and quantity of the missing decimal integers within a non-consecutive numbers range of 1st˜8th of the grayscale layers, the minimum brightness value is filled in first grayscale layer, and then decimal-integers are used sequentially to linearly adjust the brightness value of at least some of 0˜8th of the grayscale layers.
