Abstract:
A display driving method and device is provided. The display driving method determines whether each image pixel is within a range of skin color in accordance with the original grayscale data of the image pixel, and performs color casting compensation only on the image pixels within the range of skin color but not on other image pixels. The effects of color casting compensation and display are improved, and the granular feeling caused due to the color casting compensation is reduced.

Claim (Index 4):
The display driving method according to  claim 2 , wherein the predetermined boundary function comprises a first boundary function and a second boundary function, and a selected one of the image pixel is determined to be within the range of skin color when the original grayscale value of the first primary color component, the original grayscale value of the second primary color component and the original grayscale value of the third primary color component of the selected image pixel satisfy the first boundary function and the second boundary function simultaneously; otherwise the selected image pixel is determined to be out of the range of skin color;\n the first boundary function is: r+A1\u00d7g+B1\u00d7b+C1\u22650, and the second boundary function is: r+A2\u00d7g+B2\u00d7b+C2\u22640; wherein, r, g and b represent the original grayscale value of the first primary color component of the selected image pixel, the original grayscale value of the second primary color component of the selected image pixel and the original grayscale value of the third primary color component of the selected image pixel, respectively, and A1, A2, B1, B2, C1 and C2 are predetermined constants.
