CAMERA AND METHOD AND APPARATUS THEREOF FOR SWITCHING BETWEEN DAYTIME AND NIGHTTIME MODES, DEVICE, AND MEDIUM

摘要

Disclosed in the present application are a camera and a method and apparatus thereof for switching between daytime and nighttime modes, a device, and a medium. The method comprises: when the current camera mode is a nighttime mode, determining a color temperature value of the current imaging picture; by using the color temperature value and an infrared light contribution rate of picture brightness obtained on the basis of white balance statistical information of the current imaging picture, determining visible light illuminance of the current imaging picture as first visible light illuminance; and by using a numerical relationship between the first visible light illuminance and a first preset illuminance threshold, determining whether to switch the current nighttime mode to a daytime mode. The present application improves the accuracy of confirming visible light illuminance in a nighttime mode, so that the problem of repeated switching between daytime and nighttime modes can be effectively mitigated.
