s301, when a screen of the terminal is lightened, acquiring a region with a display contrast meeting a preset adjustment condition on the screen as a target region to be adjusted;
optionally, the preset adjustment condition includes any one of:
the display contrast is strongest;
the display contrast is greater than or equal to a preset contrast threshold.
It should be noted that the displaying of the strongest contrast may be an area with the largest display contrast value among all areas of the screen, where the area may be one or more, and the area is taken as a target area to be adjusted, for example, as shown in fig. 4, the screen is divided into 9 areas with the same size, and the displaying of the strongest contrast may be 1 area or 2 areas, where the number of the areas with the strongest display contrast should be any integer value greater than or equal to 1 and less than or equal to the total number of divided areas of the screen, it should be noted that the screen may be divided into several areas, where the number of the areas should be greater than or equal to 1, the area size and the shape of the divided areas may be different or the same, and the manner of dividing the areas may be regular or irregular division.
It is to be understood that the displaying contrast ratio equal to or higher than the preset contrast threshold may be that when the displaying contrast ratio equal to or higher than the preset contrast value is displayed in all screens, the regions are taken as target regions to be adjusted, the regions may be one or more, the regions are taken as target regions to be adjusted, for example, as shown in fig. 4, the screen is divided into 9 regions with the same size, the displaying contrast ratio equal to or higher than the preset contrast threshold may be 1 region or 2 regions therein, the number of the regions with the displaying contrast ratio equal to or higher than the preset contrast threshold should be any integer value greater than or equal to 1 and less than or equal to the total number of the divided regions of the screen, it should be noted that the screen may be divided into a plurality of regions, the number of the regions should be equal to or higher than 1, the area size and the shape of the divided regions may be different or the same, and the manner of dividing the region may be regular division or irregular division. (ii) a
Preferably, the preset contrast value may be 200: 1 or infinity or infinitesimal. In practical applications, the technician may also adjust this contrast value according to the actual situation.
Optionally, when the screen of the terminal is lighted up, before acquiring the region with the display contrast meeting the preset adjustment condition on the screen as the target region to be adjusted, the method further includes:
detecting whether the reflection condition of the face of the user to the light emitted by the screen of the terminal meets a preset adjusting condition or not;
if yes, acquiring an area with the display contrast meeting the preset adjustment condition on the screen as a target area to be adjusted.
It should be noted that, detecting whether the reflection condition of the user's face to the light emitted by the screen of the terminal meets a preset adjustment condition, detecting the reflection condition of the user's face to the light emitted by the screen of the terminal through the front-facing camera, and if the detected reflection result meets the preset adjustment condition, taking the area on the screen where the display contrast value meets the preset adjustment condition as the target area to be adjusted.
Optionally, the detecting of the reflection of the light emitted from the screen of the terminal by the face of the user includes at least one of:
when the reflectivity is less than or equal to a preset threshold value, the screen display is not adjusted;
and when the reflectivity is larger than a preset threshold value, adjusting screen display.
It can be understood that detecting the reflection condition of the user's face to the light emitted by the screen of the terminal is mainly to detect whether the reflectivity is greater than a preset threshold, when the reflectivity is detected to be greater than the preset threshold, that is, the preset adjustment condition is satisfied, the screen display needs to be adjusted, and when the reflectivity is less than or equal to the preset threshold, that is, the preset adjustment condition is not satisfied, the screen display does not need to be adjusted.
Preferably, the preset reflectivity threshold may be 10%.
Optionally, before detecting whether a reflection condition of the user's face to light emitted by the screen of the terminal satisfies a preset adjustment condition, the method further includes:
detecting whether the ambient light of the environment where the terminal is located meets a preset condition;
this is done by detecting the reflection of the user's face from the light emitted by the screen of the terminal.
It should be noted that when it is detected that the ambient light of the environment in which the terminal is located satisfies the preset condition, the auxiliary detection of the reflection of the light emitted from the screen of the terminal by the face of the user is performed.
Optionally, detecting the ambient light of the environment in which the terminal is located includes at least one of:
