In the prior art, there are two ways to determine the brightness information of ambient light:
the first is to transmit the external environment light to the surface of the photosensitive device by using the light guide column, and this way needs to ensure that the screen light of the display screen cannot interfere with the photosensitive device, so that a larger black edge needs to be adopted to avoid the interference of the screen light signal to the photosensitive device. When the terminal is specifically a mobile phone, as shown in fig. 1, fig. 1 is a partial screenshot of a plane where a display screen of the mobile phone is located, a left circular region in fig. 1 is a camera of the mobile phone, a right small circular region in fig. 1 is a position region of a photosensitive device, an annular region outside the small circular region is a black edge region, and a region above the photosensitive device is a receiver of the mobile phone.
The second is to place the light sensing device directly under the display screen, as shown in fig. 2, the terminal obtains the screenshot information of the current display screen through the total brightness information of the screen light and the ambient light collected by the light sensing device, and obtains the screen color information and the screen brightness level on the current display screen from the screenshot information, the terminal fits the screen color information and the screen brightness level in a linear fitting manner to determine the display brightness information on the display screen, and then the terminal determines the brightness information in the current ambient light by using the total brightness information of the screen light and the ambient light and the display brightness information obtained by the light sensing device, and adjusts the brightness of the display screen according to the brightness information in the ambient light, because the screen color information on the display screen obtained by the terminal is color information and not single color information, the local data obtained when the terminal performs linear fitting is nonlinear data, and the accuracy of the display brightness information calculated by the terminal according to the nonlinear data is low, so that the accuracy of the brightness information in the ambient light determined by the terminal is low.
