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