The invention discloses an image processing method and apparatus. An image comprises n image blocks. The method comprises the steps of judging whether an input image block is an edge of the image or not; when the image block is determined to be the edge of the image, performing edge enhancement processing on the image block to obtain edge enhancement intensity information of the image block; according to a preset mapping relationship between the edge enhancement intensity information and color suppression intensity, judging an interval, where the edge enhancement intensity information is located, in the preset mapping relationship between the edge enhancement intensity information and the color suppression intensity; according to the interval, selecting the color suppression intensity of the image block; and performing color suppression processing on the chromaticity of the image block by using the color suppression intensity, thereby obtaining a chromaticity value of the image block subjected to the color suppression processing. By adopting the scheme, the image quality can be improved while the calculation amount of image processing is reduced, and the cost is reduced.
