Abstract

The embodiment of the invention discloses a method for obtaining ambient light intensity and terminal equipment, relates to the technical field of communications, and is used for solving the problem that a detection result of ambient light in the prior art is inaccurate. The method comprises the following steps: acquiring a first difference, wherein the first difference is an absolute value of a difference between a first ambient light intensity measurement value and a second ambient light intensity measurement value; acquiring a second difference, wherein the second difference is an absolutevalue of a difference between a first gray scale value and a target gray scale value, the first gray scale value is a gray scale value of a first target image, the target gray scale value is the second gray scale value or the gray scale value after target processing of the first gray scale value, and the second gray scale value is a gray scale value of a second target image; and calculating a target ambient light intensity value according to the first ambient light intensity measurement value, the first difference, the second difference, and the first gray scale value. The scheme is specifically applied to a scene for measuring ambient light intensity.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a method for acquiring ambient light intensity and a terminal device. Background technique [0002] With the continuous development of terminal technology, the application of terminal equipment is becoming more and more extensive. In order to enable human eyes to better watch the content on the screen when the light in the environment where the terminal device is located changes, the terminal device has an automatic screen brightness adjustment function. [0003] At present, a light sensor is usually installed in the terminal device, and the light sensor detects the ambient light intensity in the environment where the terminal device is located, and then according to the ambient light intensity and the mapping relationship between the ambient light intensity and the screen brightness value, determine the The screen brightness value correspondi...
