  • Camera, method, apparatus and device for switching between daytime and nighttime modes, and medium
    Patent number: 11962909
    Abstract: Provided are a camera, a method, apparatus and device for switching between a day mode and a night mode, and a medium. The method includes steps described below. In response to a current camera mode being the night mode, a color temperature value of a current imaging picture is determined. Visible light illuminance of the current imaging picture is determined by utilizing the color temperature value and an infrared light contribution ratio of picture brightness obtained based on white balance statistical information of the current imaging picture and used as first visible light illuminance. It is determined whether to switch from the current night mode to the day mode by utilizing a magnitude relationship between the first visible light illuminance and a first preset illuminance threshold.
