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.
