Method for automatically adjusting display screen brightness based on pupil size

Abstract

The invention discloses a method for automatically adjusting the brightness of a display screen based on the pupil size, and the method comprises the following steps: step 1, starting the authority ofa front camera, collecting an eye image, and calculating the pupil diameter; step 2, collecting pupil data of a user and custom screen brightness in the three modes; step 3, acquiring data changes ofthe pupil diameter of the user under different ambient illuminance in real time; and step 4, comparing the pupil diameter at the current moment with the pupil diameter at the previous moment, and adjusting the most appropriate screen brightness in the current environment. According to the invention, the brightness of the display screen can be automatically adjusted, extra photosensitive devices and the like are not needed to save resources, the problems of misjudgment and the like caused by adjusting the brightness of the display screen based on environment comparison can be avoided, and thevisual experience of a user is improved.

Description

technical field [0001] The invention relates to a method for automatically adjusting the brightness of a display screen based on pupil size Background technique [0002] With the increasing development of information technology and high-tech industries, people use display terminals more and more frequently in their work, study and life. In order to improve the convenience and comfort of people when using the display terminal, it is very important to adjust the brightness of the display terminal.

Problems solved by technology

Although manual brightness adjustment can intuitively reflect the user's most real preference for screen brightness, the operation is inconvenient and lacks intelligence, which has a certain impact on user experience

When the automatic adjustment detects the light intensity of the surrounding environment, it may cause misjudgment of the environment due to the partial area being blocked, which makes the screen brightness change frequently and even leads to adjustment errors. The main judgment basis of the automatic adjustment method is the environment. It is far from the user's subjective feeling, does not consider adapting to the human eye, and sometimes does not match the user's real needs, and the calculated screen brightness is not necessarily the most suitable for the comfort of the human eye
