Problems solved by technology

[0004] However, the screen brightness of the display terminal obtained by adjusting according to the illumination change is usually not the screen brightness required by the user, and cannot meet the needs of each user.
Moreover, since the human eye is directly facing the screen of the display terminal, the light seen by the human eye is the light from the back direction of the screen of the display terminal, and the light sensed by the light source sensor is the light from the front direction of the screen of the display terminal. The direction of the light sensed by the light source sensor is opposite, and the light change sensed by the light source sensor is often not the light change seen by the human eye, so there is a large error with the actual screen brightness requirement of the user's human eye, which cannot meet the user's screen brightness requirement

Embodiment Construction

[0042] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0043] see figure 1 , the present invention provides a method for controlling the brightness of a display terminal screen, comprising the following steps:

[0044] The first step is to collect the human eye image of the current user's face;

[0045] The second step is to identify the collected human eye images and obtain the iris information and pupil diameter information of the current user;

[0046]The third step is to judge whether the current user's iris information is the pre-stored user's iris information, and if so, according to the correspondence between the preset iris information of each user, the pupil diameter information and the brightness value of the display terminal screen, obtain Display the brightness value of the termina...

Abstract

The invention discloses a method for controlling screen luminance of a display terminal. The method comprises the steps as follows: step one, a human eye image of the face of a current user is collected; step two, the collected human eye image is recognized, and iris information and pupil diameter information of the current user are obtained; and step three, whether the iris information of the current user is that of a pre-stored user is determined, if yes, according to a preset corresponding relation between iris information and pupil diameter information of each user and a screen luminance value of the display terminal, the screen luminance value of the display terminal corresponding to the iris information and the pupil diameter information of the current user is obtained, and then the screen luminance display of the display terminal is controlled. According to the method for controlling the screen luminance of the display terminal and the display terminal, the screen luminance of the display terminal can be adjusted automatically, requirements of the user are met, the power consumed by the display terminal is saved, the power consumption of the display terminal is reduced, and the daily power fare expense of the user is reduced.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a method for controlling the screen brightness of a display terminal and a display terminal thereof. Background technique [0002] With the continuous development of science and technology in our country, home appliances such as monitors, projectors, all-in-one machines, computers, televisions, video cameras, and cameras are becoming more and more popular in people's daily life, and have become an indispensable part of people's lives. [0003] At present, the display brightness of the screen of the display terminal is getting higher and higher. For display terminals currently on the market, in order to realize automatic screen brightness control, the principle is: install a light source sensor on the front of the display panel of the display terminal, and when the external (mainly the front of the display terminal) lighting conditions change, the The sensor senses ...
