In the present invention, the brightness mode is used to describe the illumination relationship between the current screen and the lamp; the corresponding brightness difference can be determined according to the brightness mode, and the brightness difference refers to the difference between the screen brightness and the lamp brightness.
In this embodiment, the screen brightness may be set by obtaining the brightness level of the screen playing content. It can be understood that the invention adjusts the brightness of the lamp by setting the screen brightness first and then adjusting the brightness of the lamp by the setting result of the screen brightness, and the mode is further optimized on the basis of the automatic brightness adjustment of the existing screen. The automatic brightness adjustment function of the existing screen is utilized, but the control logic of the automatic brightness adjustment of the screen is changed, so that the brightness adjustment of the screen is associated with the brightness control of the lamp, the aim of preventing the brightness of the lamp serving as the screen backlight from being too high or too low is achieved, and the problem that the pupil needs to be enlarged to receive more light to cause fatigue transition when a user watches in a dark environment or the visual fatigue is caused by tight height of the optic nerve when the user watches in a bright environment is prevented.

As a preferred embodiment of the present invention, the determining the brightness mode of the image captured by the screen camera includes:
acquiring an image through a screen camera;
and performing light source identification on the image, setting the lamp to be in a direct lighting mode if the light source is identified, and setting the lamp to be in a backlight mode if the light source is not identified.
In this embodiment, the image acquired by the screen camera may be used for light source identification, and if the light source is identified, the light source may be directed to the screen, and at this time, the screen is set to be in a direct-directing mode, otherwise, the screen is in a backlight mode. In the backlight mode, the lamp cannot directly illuminate the screen, mainly due to the relative orientation of the lamp and the screen or the shielding of the user in front of the screen. The invention combines the screen brightness when adjusting the brightness of the lamp, which is equivalent to adjusting the back illumination when the user watches the screen, and controls the brightness of the environment where the screen is positioned.

determining the position of each target pixel point in the target set in a three-dimensional coordinate system, and determining a plurality of connected domains according to the adjacent relation of the target pixels;
and respectively calculating the ratio of the number of target pixel points of each connected domain to the total number of the target pixel points, judging whether the maximum ratio is greater than a second set threshold, if so, identifying the light source, otherwise, not identifying the light source.
In this embodiment, the color value refers to RGB values of each pixel, including an R value, a G value, and a B value, and the processing of the image according to the present invention is based on an RGB mode. In the present application, it is prior art to calculate the brightness value of the pixel point according to the color value, and the simplest formula may be Y (brightness) = (0.299R) + (0.587G) + (0.114 × b).
In this embodiment, the calculated brightness values are arranged from large to small, the deviation between two adjacent brightness values is calculated from large to small, the deviation between the brightness values is equal to the ratio of the difference between the brightness values of two pixels to the brightness of any one of the two pixels, and the denominator can be selected as the previous or next pixel. In the present embodiment, for a light source which has high luminance and in which the difference in luminance between points emitting light in the light source is extremely small on an image, the first set threshold value may be set within 0.01.

In this embodiment, the first brightness difference in the direct lighting mode is smaller than the second brightness difference in the backlight mode, and the first brightness difference may be set to 10% to 30% of the current screen brightness, where the first brightness difference may be set to 10% to 15% of the current screen brightness, and the second brightness difference may be set to 16% to 30% of the current screen brightness, and may be specifically customized by the user.
As a preferred embodiment of the present invention, the obtaining the quality level of the screen playing content includes:

In the present embodiment, the different screen resolutions and the corresponding playing contents are classified according to the requirements of the different picture contents on brightness, and the higher the grade is, the higher the brightness value is required to ensure the display effect. It should be noted that, the dividing method of the present invention is performed by combining the relationship between the physical resolution of the screen itself and the resolution of the data to be displayed, so that the dividing is more suitable for the actual situation.

In this embodiment, the brightness range may be determined by the obtained brightness value floating up and down by 15% to 30%, and when the floating range exceeds the brightness range of the device, the actual brightness range of the device is taken.
In this embodiment, the determined brightness range is divided into five levels, each level has an equal brightness value range width, and the middle value of each brightness value range is taken as the screen brightness corresponding to the level.
As a preferred embodiment of the present invention, the setting of the brightness range of the lamp according to the screen brightness and the brightness difference includes:
determining a basic brightness value according to the current time interval;
setting the sum of the basic brightness value and the brightness difference as a central value of the lamp brightness;
and determining the upper and lower limits of the brightness of the lamp according to the central value and the preset brightness deviation so as to obtain the brightness range of the lamp.
In this embodiment, a basic brightness value is preset for each time period, and the sum of the basic brightness value and the brightness difference can be equal to the central value of the lamp brightness. The preset brightness deviation is usually 20% -30% of the central value, for example 20%, and if the central value is 100, the brightness range of the lamp is 80-120.
