Abstract
This application relates to the field of communications technologies, and provides an ambient light detection method and a terminal, to help save top space of a mobile phone, help increase a screen-to-body ratio of the mobile phone, and help improve user experience. The method includes: obtaining, by the terminal, a first luminance value of each first pixel, where each first pixel corresponds to one first luminance value; obtaining, by the terminal, a second luminance value of each region based on first luminance values of all first pixels included in each region, where each region corresponds to one second luminance value; obtaining, by the terminal, a luminance value of current ambient light based on all the second luminance values; and adjusting, by the terminal, luminance of the display based on the luminance value of the ambient light.
