Ordinary people can also have video and audio conversations and communicate with each other on the Internet through the camera. In addition, people can also use it for various popular digital images, audio-visual processing and so on.
The working principle of the camera is to project the optical image of the scene onto the surface of the image sensor through the lens, and then convert it into an electrical signal, which is converted into a digital image signal after A/D (analog-to-digital conversion) conversion, and then sent to a digital signal processing chip (DSP) for processing, and then transmitted to a computer for processing through a USB interface, and the image can be seen through a display.
