  Video - Wikipedia, the free encyclopedia
Video (from Latin, "I see") is the technology of processing electronic signals for representing moving pictures.
Video can be created with mechanical cameras (capture on celluloid film), video cameras (capture electric signal in PAL or NTSC formats) or digital cameras (commonly capture in digital MPEG-4 or DV formats).
In the UK, the term 'video' is often used informally to refer to both video recorders and video cassettes; the meaning is normally clear from the context.

 VIDEO CAMERAS   (Site not responding. Last check: 2007-11-07)
A video camera has a lens that focuses an image onto a light sensitive chip called a CCD (charged coupling device).
The matrix on this chip performs the same function as the emulsion on film, except this matrix continuously generates a signal that is fed through an amplifier and recorded onto a video cassette either within the camera or in a separate recording unit.
High-end cameras have a 3 chip system that separates light into components of red, green and blue which are individually stabilized and amplified.

 Digital & Video Cameras
Digital vs. Video: Video cameras are the older of these technologies, but they still have the advantage of outputting "live" (30 frames / second) images to standard TV monitors.
This output can be either directly to a computer in the case of "dedicated microscope cameras", or to an integrated LCD screen on the camera itself, as in the case of consumer hand-held cameras.
A digital camera is one which converts the analog signal to digital within the camera and outputs a digital signal.

Again, this is a tremendous advantage over digitizing analog video, which must be done in real time.
