An image detection method includes determining, by a terminal in a skin detection mode, a to-be-detected original image in a raw format based on a to-be-detected feature, processing the to-be-detected original image according to a preset rule corresponding to the to-be-detected feature to obtain a detection-specific image, determining a normal image that is in a Joint Photographic Experts Group (JPEG) format, detecting the detection-specific image to determine a detection result image, and determining a to-be-displayed image based on the detection result image and the normal image.
