Abstract

A light intensity detection method includes: determining whether light intensity detection needs to be performed; detecting whether there is a finger touch in an optical detection region of an optical fingerprint sensor if light intensity detection needs to be performed, wherein the optical detection region is located in at least one part of a display region of a display; enabling a light intensity detection function if no finger touch is detected, and collecting light intensity data by using the optical fingerprint sensor; and processing the collected light intensity data, and calculating a value of current ambient light intensity according to the light intensity data.
