A method for automatically adjusting the brightness of a display screen based on pupil size

Abstract

The invention discloses a method for automatically adjusting the brightness of a display screen based on pupil size, comprising the following steps: step 1: open the authority of the front camera, collect eye images and calculate the pupil diameter; step 2: collect user pupil data and Customize the brightness of the screen; Step 3: Obtain real-time data changes of the user's pupil diameter under different environmental illuminance; Step 4: Compare the pupil diameter at this moment with the pupil diameter at the previous moment, and adjust the most suitable screen in the current environment brightness. The invention can automatically adjust the brightness of the display screen without using additional photosensitive devices to save resources, and can avoid problems such as misjudgment caused by adjusting the brightness of the display screen based on the environment contrast, thereby improving the user's visual experience.

Description

Technical field [0001] The present invention relates to a method of automatically adjusting display brightness based on pupil size. Background technique [0002] With the increasing development of information technology and high-tech industries, people use the frequency of display terminals in work, learning and life. In order to improve the convenience and comfort when using the display terminal, the brightness adjustment of the display terminal is critical. The adjustment of the screen of the mobile terminal can provide a better usage and viewing experience for users. For screen brightness adjustment techniques for displaying terminals, it is generally divided into manual adjustment and automatic adjustment. Usually manually adjust the mode of operation: The user completes the screen adjustment based on the progress bar or the brightness adjustment button of the brightness range according to the preference. Automatic adjustment generally uses photosensitive devices such as ligh...

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
