Ccd Cameras Definition

All cameras take light and convert it into a video signal. The quality of this captured video signal is dependent upon the quality of the camera and CCDs are often what determine this quality.


Definition of a CCD


CCD stands for Charge Coupled Device(s). They are responsible for turning RGB light into electronic RGB signals. They are usually located directly behind the lens of the camera.


Types of CCDs


Depending on the quality of the camera, there may be one or multiple CCDs to collect RGB data. Budget consumer cameras usually only have one CCD to process the RGB signal. Higher end cameras may have three or more, one for each Red, Blue and Green signal.


Features of the CCD


Multi-CCD cameras are often paired with a beam splitter or prism block which redirects the incoming white light into its respective RGB CCDs. This allows for clearer color definition.


Identification of the CCD


A CCD looks like a standard computer chip and it is advisable to take it out occasionally for a gentle cleaning.


Higher Quality CCDs


A higher quality CCD may contain millions of pixels to make the image look as vibrant as possible.
