Embodiment Construction

[0077] The traditional method detects the light intensity of the surrounding environment of the terminal equipment by installing a light intensity sensor on the terminal equipment, and adjusts the brightness of the terminal equipment screen according to the change of the detected light intensity, so as to protect the user's eyesight and improve the user experience. Purpose. For example, when the light intensity sensor detects that the surrounding environment is getting darker, the user's glare can be reduced by dimming the brightness of the screen; Adjust the brightness to avoid the problem that the content on the screen cannot be seen clearly due to the bright surrounding environment.

[0078] However, the detection range of the light intensity sensor is small, and usually only the light intensity in the area directly in front of the light intensity sensor can be detected. For example, assuming that the light intensity sensor is installed next to the camera of the terminal d...

Abstract

The embodiment of the present application discloses a screen brightness adjustment method and device, which are used to improve the accuracy of adjusting the screen brightness of a terminal device and reduce costs. Wherein, the method includes: acquiring multiple first eye images of the user, where the first eye images are images obtained by photographing the user's eyes; Perform processing to obtain the pupil state corresponding to each first eye image in the plurality of first eye images; according to the order in which the plurality of first eye images are taken and the plurality of first eye images According to the pupil state corresponding to each first eye image, the change trend of the pupil state of the user is obtained; and the brightness of the screen is adjusted based on the change trend of the pupil state.

Description

technical field [0001] The present application relates to the field of computers, in particular to a method and device for adjusting screen brightness. Background technique [0002] In order to protect the eyesight of users and improve user experience, light intensity sensors are usually installed in terminal equipment to perceive the intensity of ambient light around the terminal equipment, and then adjust the brightness of the screen of the terminal equipment according to the change of perceived light intensity, reducing the Damage to the user's vision caused by too bright or too dark. [0003] However, the cost of the light intensity sensor is relatively high, and it can only perceive the light intensity in a small part of the space area, and the sensing range is small, so it is difficult to accurately adjust the brightness of the screen of the terminal device. Contents of the invention [0004] Embodiments of the present application provide a method and device for adj...
