Abstract
This application relates to the field of communications technologies, and provides ambient light and optical proximity detection methods, a photographing method, and a terminal, so that an entire display screen of the terminal is used to display a user interface, and this improves user experience. The method specifically includes: controlling, by a terminal, some areas of a display screen to display a black picture for a plurality of times; and when the areas display the black picture, obtaining approaching data of the external object detected by an optical proximity sensor to control turning on or off of the display screen.
