Abstract

The invention discloses a method for AI automatic identification and screen brightness adjustment. The method comprises the following steps: a, an extraction step: extracting the brightness value of each point location of the current display content of a display screen; b, a light sensing step: sensing a current ambient light illuminance value through a sensor; c, an AI calculation step: performing calculation processing on the brightness value of each point location of the current display content of the display screen and the current ambient illuminance value to obtain an adjusted picture; and d, a dimming step: replacing the current display content of the display screen with the adjusted picture. In the AI calculation step, the adjusted picture is the brightness value of each point position of the current display content of the display screen, and the saturation and the color gradation are improved or reduced relative to the reference value of the display brightness of the display screen and the built-in color contrast template, so that the brightness, the color contrast and the saturation of the picture are changed on the whole; and discomfort and fatigue of human eyes are greatly reduced.

Description

Technical Field

[0001] The present invention relates to the field of automatic screen brightness adjustment, and in particular to a method for AI to automatically identify and adjust screen brightness. Background Art

[0002] When the human pupil is exposed to a high ambient light intensity, it will automatically contract to adjust the light flux. If the screen brightness of an electronic device is too different from the ambient light intensity, the user will not be able to see the screen clearly or will feel glared by the screen. To solve this problem, current electronic devices will have an automatic brightness adjustment program that automatically adjusts the screen backlight brightness of the device according to the ambient light intensity detected by the device's brightness sensor, allowing users to enjoy the most suitable screen brightness for their eyes in different environments without having to do it themselves.

[0003] However, the current display content on the display screen also has differences in light and dark areas, color levels and saturation, which causes the human eye to feel uncomfortable and tired after long-term use due to the different brightness of the display, thereby aggravating the degree of myopia or astigmatism or causing myopia or astigmatism. Summary of the invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art.

[0005] To this end, the technical solution adopted by the present invention to solve the technical problem is: a method for automatically identifying and adjusting screen brightness by AI, including a display screen and a sensor, including the following steps:

[0006] a. Extraction step: used to extract the brightness value of each point of the current display content of the display screen;

[0007] b. Light sensing step: sense the current ambient light value through the sensor;

[0008] c. AI calculation step: Calculate the brightness value of each point of the current display content of the display screen and the current ambient light illumination value to obtain the adjusted picture;

[0009] d. Dimming step: Replace the current display content of the display screen with the adjusted image.

[0010] Preferably, the AI ​​calculation step also includes noise filtering to eliminate noise in the current display content of the display screen.

[0011] Preferably, the AI ​​calculation step also includes calculating a reference value of the display brightness of the display screen based on a comparison between the current ambient light illumination value and the brightness value of each point of the current display content of the display screen.

[0012] Preferably, the AI ​​calculation step also includes a built-in color comparison template.

[0013] Preferably, the adjusted image in the AI ​​calculation step is to increase or decrease the brightness value, saturation and color level of each point of the current display content of the display screen relative to the reference value of the display brightness of the display screen and the built-in color control template.

[0014] Preferably, the brightening or dimming process is to increase or decrease the brightness value of each point of the current display content of the display screen by 10 to 300 NIT relative to the reference value of the display brightness of the display screen.

[0015] Preferably, the brightening or dimming process is to increase or decrease the brightness value of each point of the current display content of the display screen by 50 to 150 NIT relative to the reference value of the display brightness of the display screen.

[0016] The beneficial effects of the present invention are as follows: (1) according to the comparison between the current ambient light illuminance value and the brightness value of each point of the current display content of the display screen, the reference value of the display brightness of the display screen is calculated, and the image adjusted in the AI ​​calculation step is to increase or decrease the brightness value, saturation and color level of each point of the current display content of the display screen relative to the reference value of the display brightness of the display screen and the built-in color comparison template, thereby changing the brightness, color contrast and saturation of the image as a whole, greatly reducing the discomfort and fatigue of the human eye;

[0017] (2) Noise filtering eliminates the noise of the current display content on the display screen, further reducing the discomfort and fatigue of the human eye and making the picture softer. DETAILED DESCRIPTION
