Optionally, the second preset threshold is greater than the first preset threshold, or the second preset threshold is equal to the first preset threshold. When current ambient light intensity reaches the second preset threshold value, the shooting device can normally and clearly shoot the shot object. At the moment, the processor triggers a shooting instruction to control the shooting device to automatically shoot and collect the shot objects in the shooting area.
In the adaptive dimming control method provided by this embodiment, a light supplement instruction is triggered when the optical sensor detects that the initial ambient light intensity of the shooting area is smaller than a first preset threshold, the processor controls the light supplement light source to supplement light to the shooting area with the target light supplement light intensity according to the initial ambient light intensity, and when the current ambient light intensity reaches a second preset threshold, the shooting instruction is triggered to control the shooting device to shoot.

s1001, dividing the initial light intensity interval according to the difference degree between the initial ambient light intensity and a first preset threshold value.
And comparing the first preset threshold value with the initial ambient light intensity to obtain the difference degree. According to the difference degree, the difference degree is divided into initial light intensity intervals with different levels from small to large, the smaller the difference degree is, the lower the level interval is, if the difference degree is divided into a first initial light intensity interval in 1-10 light intensity units, the difference degree is divided into a second initial light intensity interval in 11-20 light intensity units, the difference degree is divided into a third initial light intensity interval in 21-30 light intensity units, and the like. The more difference degrees are divided into the less initial light intensity intervals, and the storage amount and the processing amount of data are reduced.

After the processor determines the light intensity of the target light supplement, the light supplement lamp source is controlled to send the light intensity of the target light supplement, the shooting area on the base is supplemented with light, the light intensity of the shooting area is the current ambient light intensity, and the current ambient light intensity is the sum of the initial ambient light intensity and the light intensity of the target light supplement in theory. In actual operation, inevitable loss is caused due to the influence of the surrounding environment, and the actually obtained current ambient light intensity is smaller than the sum of the initial ambient light intensity and the target supplementary light intensity.
