How does a USB Vision Camera Module work?

The USB vision camera module works by converting light from the environment into electronic signals. Here’s a brief overview of its operation:

1. Image Capture: The camera module has a lens that focuses light onto an image sensor. This sensor converts the incoming light into electronic signals.
2. Processing: The captured signals are then processed by the camera’s onboard chip to create a digital image or video.
3. Transmission: Finally, the processed data is sent to a computer or another device through a USB interface.
