In this embodiment, it is recognized that the number of the extracted preset illumination intervals is two or more, so that there is an overlapping portion in the preset illumination intervals, for example, when the illumination intensity is 50000Lx, the overlapping portion is located in the overlapping portion of two adjacent preset illumination intervals, where the brightness value data corresponding to one preset illumination interval is 40, and the brightness value data corresponding to the other preset illumination interval is 45, then two brightness value data of 40 and 45 are extracted.
Specifically, after the illumination intensity data is input into the brightness matching model, if the illumination intensity data falls on the overlapped part of two adjacent preset illumination intervals, extracting the brightness value data corresponding to the two preset illumination intervals;
further, the flow rate of the people near the display at this time is acquired and compared with a preset flow rate threshold value, when the flow rate of the people is smaller than the flow rate threshold value, a preset illumination interval corresponding to smaller brightness value data is selected from the two extracted brightness value data, and a dimming instruction is output based on the selected preset illumination interval as a matching result, namely based on the smaller brightness value data in the two brightness value data. When the flow of people is less, darker brightness value data can be selected, and users watching the screen are fewer due to less flow of people, and at the moment, the function of power saving is mainly considered.
Further, when the human flow rate is greater than the human flow rate threshold value, a preset illumination interval corresponding to the larger brightness value data is selected from the two extracted brightness value data, and a dimming instruction is output based on the larger brightness value data of the two brightness value data. When the flow of people is large, a brighter brightness value data is selected, so that a user can be attracted to watch a screen, and the brightness of the display is adjusted more flexibly.
