What Does CCD Stand for in Cameras?
In cameras, CCD is an acronym for charge-couple device, which is a silicon chip that converts light into a digital signal. In the past, cameras would focus the light from the lens to create an image on film. Modern cameras use CCD chips to convert focused light captured by the lens to the digital world.

History
-
The CCD chip's underlying technology converts photons into electrons, this creates a digital signal the computer can read (Einstein's photoelectric effect). This computer memory chip became a reality in the 1960s and continues to evolve.
Significance
-
Sufficient light must hit the CCD chip in order to produce a charge. The number of pixels will represent at how many points your chip can convert light photons into electrons.
-
Features
-
The bigger the chip, the more pixels and high quality images it can produce. Many factors contribute in determining your video quality, but your CCD chip is the central factor. Your CCD chip will designate the quality of your video by how many pixels it uses to capture, store and display its images.
Identification
-
A camera CCD chip will be described by its size for example 2/3 of an inch represents the standard for a professional camera. Professional cameras will use 3CDDs in order to process different colors.
Considerations
-
Some may offer a CMOS (complementary metal oxide semiconductor) chip as an equal alternative, although similar in functions, CCD chips still holds several advantages.
