Blackhead display method and related device

The embodiment of the invention relates to the technical field of image processing, and discloses a blackhead display method, which comprises the following steps of: acquiring a face image, intercepting a specific area image from the face image, and then performing brightness enhancement and contrast enhancement processing on the original face image based on the specific area image to generate a blackhead display image. The specific area image comprises an area in the face image, the probability of generating the blackhead in the area is greater than or equal to a preset probability threshold value, so that the specific area grayscale image generated by the specific area image can better reflect the grayscale value condition of the area where the blackhead is located; the mean value of the gray values in the gray image in the specific area is not interfered by the area with the small blackhead occurrence probability (such as the interference of the background area in the face image), then brightness enhanceme
