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.

Abstract: The present disclosure provides a method and an apparatus of detecting high-frequency components in an image. The method using a first grayscale difference, a second grayscale difference to calculate the target grayscale difference with the target grayscale difference algorithm, comparing the target grayscale difference with a preset grayscale threshold value to determine whether the image pixel to be detected is a high-frequency image pixel, and adjusting the actual grayscale value of the high-frequency image pixel to reduce the difference between the actual grayscale value of the high-frequency image pixel and the original grayscale value. It can optimize the detection process of high-frequency components in the image and improve the poor display caused by the color shift compensation algorithm to improve the display quality.
