Specifically, the target reflection amount decrease amplitude is set according to the hardware characteristics of the display device and preset in the display device. The target reflection amount decrease amplitude may be different for different models of display devices. Specifically, the gray scale value variable corresponding to the preset reflection quantity is determined, and the gray scale values of all the pixel points of the target reflection area are adjusted according to the determined gray scale value variable, so that the purpose of reducing the reflection quantity of all the pixel points is achieved. In the embodiment of the invention, the adjusted image is generated according to the reflection quantity of all the pixel points of the reduced target reflection area, and the generated adjusted image is sent to the display screen for display, so that the display effect of the light reflection area is improved.
The magnitude of the reduced reflection amount of the target reflection area may also be adjusted by setting the target reflection amount reduction amplitude by the user, for example. Specifically, a display image adjustment application program is preset in the display device, and the user can input an adjustment target reflection amount reduction amplitude value through the display image adjustment application program, and the display image adjustment application program generates a reflection amount reduction amplitude value confirmation instruction according to the target reflection amount reduction amplitude value input by the user. After the controller acquires the reflection amount reduction amplitude confirmation instruction, the reflection amounts of all the pixel points of the target reflection area are reduced according to the target reflection amount reduction amplitude.
In the embodiment of the invention, after the target reflection area is determined, the purpose of adjusting the brightness and the chromaticity of the light reflection area can be achieved by reducing the reflection amount of all pixel points contained in the target reflection area. For example, the reflection amounts of all the pixel points of the target reflection area may be reduced according to the preset reflection amount reduction amplitude.
According to the display screen reflection amount adjusting method, coordinate values of target reflection points are determined according to the obtained three-dimensional coordinate values of the target human eye graph and the obtained three-dimensional coordinate values of the target light source graph, wherein the target reflection points are reflection points of the target light source graph on the display screen; determining a target reflection area by taking a target reflection point as a circle center according to a preset radius parameter; the reflection quantity of all the pixel points of the target reflection area is reduced, an adjusted image is generated according to the reflection quantity of all the pixel points of the target reflection area after reduction, the brightness and the chromaticity of the image displayed in the light reflection area are adjusted, and the display effect of videos and images is improved.

In the embodiment of the present invention, another implementation method for reducing the reflection amounts of all the pixels in the target reflection area in S702 is described in detail based on the embodiment provided in fig. 7. As shown in fig. 10, the method includes:
s1001: and obtaining target distances between all pixel points contained in the target reflection area and the target reflection points.
In the embodiment of the present invention, it is considered that the brightness due to refraction of light gradually decreases from the center point position to the edge region in the light reflection region. Therefore, the target reduction amplitude of the reflection quantity corresponding to the pixel points at different positions of the target reflection area can be adjusted according to the change trend of the light reflection quantity, namely, the target reduction amplitude of the reflection quantity is adjusted according to the distance between the pixel points and the target reflection point. Specifically, the target distance corresponding to the pixel point is determined according to the coordinate value of the pixel point and the coordinate value of the target reflection point, so that the target distances corresponding to all the pixel points in the target reflection area are obtained.
S1002: and determining a target reduction amplitude corresponding to the target distance of each pixel point according to a preset relation function, and reducing the reflection quantity of each pixel point according to the target reduction amplitude corresponding to each pixel point.
In the embodiment of the invention, the target reduction amplitude corresponding to the target distance of each pixel point can be determined according to the preset relation function. For example, according to the preset relation function, when the target distance of the pixel point is greater than the distance threshold value of n times and less than or equal to the distance threshold value of n+1 times, the target decreasing amplitude is set to be the n+1th decreasing amplitude, where n is 0 or a positive integer, and the n+1th decreasing amplitude is less than or equal to the n-th decreasing amplitude. Fig. 11 is a schematic diagram of a second target reflection area according to an embodiment of the present invention. As shown in fig. 11, when the target distance of the pixel is greater than 0, less than or equal to the distance threshold, that is, the pixel is located in the first ring, the target decreasing amplitude of the pixel is set to be the first decreasing amplitude; when the target distance is greater than the distance threshold and less than or equal to 2 times the distance threshold, that is, the pixel is located in the second ring, the target reduction amplitude of the pixel is set to be the second reduction amplitude. The second reduced amplitude is illustratively less than or equal to the first reduced amplitude. When the second decreasing amplitude is equal to the first decreasing amplitude, that is, the decreasing amplitude of the target corresponding to the pixel point in each ring is the same, and when the second decreasing amplitude is smaller than the first decreasing amplitude, that is, the decreasing amplitude of the target corresponding to the pixel point of the outer ring is smaller than the decreasing amplitude of the target corresponding to the pixel point of the inner ring, the decreasing amplitude of the ring which is closer to the center of the circle is larger.
In the embodiment of the invention, the abscissa in the preset relation function is the target distance between each pixel point and the target reflection point, and the ordinate is the target decreasing amplitude corresponding to the pixel point. When the n+1th decreasing amplitude is smaller than the n decreasing amplitude, namely the target decreasing amplitude corresponding to the pixel point of the outer ring is smaller than the target decreasing amplitude corresponding to the pixel point of the inner ring. When the n+1th decreasing amplitude is equal to the n-th decreasing amplitude, that is, the target decreasing amplitude corresponding to the pixel point in each ring is the same.

s1201: and receiving the brightness of the target light source corresponding to the target light source graph, and determining the reflection quantity reduction amplitude corresponding to the brightness of the target light source according to a preset brightness function.
In the embodiment of the invention, the reflection quantity reduction amplitude corresponding to the brightness of the target light source can be determined according to the preset brightness function in consideration of the brightness influence of the brightness of the light source on the image displayed in the light reflection area. For example, the preset brightness function may be set as a linear function, that is, the brightness of the light source and the reflection amount decrease amplitude are in a linear correspondence. For example, the preset luminance function may be set to a nonlinear function, that is, the magnitude of the change in the magnitude of the decrease in the reflection amount decreases with an increase in the luminance of the light source.
S1202: and reducing the reflection quantity of all pixel points of the target reflection area according to the reflection quantity reduction amplitude.
In the embodiment of the present invention, the method of S1202 is identical to the method of S703 and the effect achieved in the embodiment of fig. 7, and will not be described herein.
