Automatic screen brightness adjusting method

Abstract

The invention provides a automatic screen brightness adjusting method which is characterized by comprising the following steps: calling a camera in front of a computer screen at a backstage to photograph the front face of a user and the surrounding environment of the user in real time; analyzing a picture shot by the camera and identifying the face and background of a user from the picture; analyzing the average brightness of the face and the average brightness of the background to obtain a quotient of the face and the background; and adjusting the brightness of the screen, wherein the screen brightness is in inverse relation to the quotient. The screen brightness can be accurately and automatically adjusted to the true brightness required by the user by the method.

Description

[0001] technical field [0002] The invention relates to the field of computer software, in particular to a screen brightness adjustment method. [0003] Background technique [0004] At present, the screen brightness on computer equipment is usually realized by manual setting; but sometimes, in order to adapt to changes in environmental brightness, it is also adjusted automatically. However, the current screen brightness automatically The effect obtained by the adjustment scheme is not good, and the appropriate brightness is often not obtained, so it is not favored by users; the reason is that the current automatic screen brightness adjustment method senses the brightness of the ambient light through the light sensor around the screen, but according to However, due to the large difference between the lighting angle and range of the light sensor and the viewing angle of the human body facing the computer, the screen brightness demand judged by the light sensor often differs...

[0004] At present, the screen brightness on computer equipment is usually realized by manual setting; but sometimes, in order to adapt to changes in environmental brightness, it is also adjusted automatically. However, the current screen brightness automatically The effect obtained by the adjustment scheme is not good, and the appropriate brightness is often not obtained, so it is not favored by users; the reason is that the current automatic screen brightness adjustment method senses the brightness of the ambient light through the light sensor around the screen, but according to The brightness of the screen is adjusted by sensing the results. However, due to the large difference between the lighting angle and range of the light sensor and the viewing angle of the human body facing the computer, the screen brightness demand judged by the light sensor often differs greatly from the real demand.
