The basis for digital video cameras is metal–oxide–semiconductor (MOS) image sensors. [1] The first practical semiconductor image sensor was the charge-coupled device (CCD), invented in 1969 [2] by Willard S. Boyle, who won a Nobel Prize for his work in physics. [3]
Webcam. A Logitech-branded webcam attached to a laptop. A webcam is a video camera which is designed to record or stream to a computer or computer network. They are primarily used in video telephony, live streaming and social media, and security.
Movie camera.

Video is an electronic medium for the recording, copying, playback, broadcasting, and display of moving visual media. [ 1 ] Video was first developed for mechanical television systems, which were quickly replaced by cathode-ray tube (CRT) systems, which, in turn, were replaced by flat-panel displays of several types.
Digital camera. Front and back of Canon PowerShot A 95 (c.2004), a once typical pocket-sized compact camera, with mode dial, optical viewfinder, and articulating screen.
