How a webcam works?

W elcome back friends... I'm here with another cool topic about working of a webcam. A webcam is a compact camera which can be used with computer to capture, broadcast real time videos and images. Just like every camera it has a small lens at the front through which it captures light using light-detectors known as charge-coupled device (CCD) . This CCD will convert the picture into digital format (a binary string of 0s and 1s) which is handled by the computer.
