Detailed Description

The present invention will be described in detail with reference to the following embodiments and drawings.

Please refer to fig. 1, which illustrates a daytime color night black and white in-vehicle monitoring camera according to an embodiment of the present invention, which includes a camera module 1 and a hardware circuit 2, preferably, the camera module 1 is used for collecting video and images, the camera module 1 has a light sensor 11 and a light sensing driving module 12, the hardware circuit 2 is provided with an infrared light supplement lamp 21, the light sensor 11 is electrically connected to the light sensing driving module 12, the light sensing driving module 12 is electrically connected to the hardware circuit 2, the light sensor 11 senses light changes for sensing light sensing values in ambient light and sending different code data to the light sensing driving module 12 when sensing different light sensing values, the light sensing driving module 12 is used for receiving the code data and determining the intensity of the ambient light, and controlling the hardware circuit 2 to turn on or turn off the infrared light 21 according to the different code data, and simultaneously, the shot picture is switched into black and white or color.

Preferably, the camera module 1 is in communication connection with an external application terminal 3 through an AHD or a USB for data interaction.

Preferably, the infrared light supplement lamp 21 is a 940nm light supplement lamp or a 850nm light supplement lamp.

Preferably, the light sensation value includes a light sensitivity value, an exposure value or a color temperature, and the light sensitivity value is a parameter of the intensity of the corresponding ambient light; the exposure value is a numerical value representing the light transmission capacity of the camera, and the numerical value can change in the change process of the intensity of the ambient light; the color temperature is a physical quantity representing the color of the light source.
