what is CCD in DVcameras?

Answer 1

CCD = Charge Coupled Device. It's the chip that converts the light into electrical signals that are then stored on whatever medium you're using.

Answer 2

A CCD or a Charged Coupled Device is a sensor that detects and processes the light that comes through the camcorder lens. The CCDs task is to interpret the RGB (red, green, and blue) color spectrum to produce an image with accurate colors.


There are two things you should compare:
1. Size
2. Quantity

Size
A CCD will be measured in inches between 1/6 of an inch up to 1 inch. A larger CCD is a good thing. Consumer digital camcorders will have a 1/6, 1/4, or 1/3 inch CCD while professional or prosumer camcorders will have 1/3, 1/2, or 2/3 inch CCDs.

Quantity
Camcorders can come with either 1 CCD or 3 CCDs. A camcorder with 1 CCD has 1 chip or sensor to produce the red, blue, and green colors. A 3 CCD camcorder has one chip for the reds, one chip for the blue, and one chip for the blue, thus almost always providing a better image over a camcorder with 1 CCD. 3 CCD camcorders also provide better low light video.

Answer 3

dvDigest has best explained all the tech stuff, realize though that if you're basing a purchase decision on the size of the CCD, you're better off physically comparing models at a retailer, and judging with your own eye as to the quality difference. The performance of CCDs have changed over the years and although bigger used to be better, the improvement on the technology has allowed some camera's, for example, with 1/4CDDs to actually outperform models that might have 1/3CCDs. However, a you can still rely on a 3CCD to outperform a 1CCD camera (unless you start comparing High Definition 1080 to Standard Definition 480) since the burden of the gathering the color information is being split between 3CCDs (red,green,blue) instead of just one, therefore increasing the cams ability to reproduce accurate color usually with a better signal to noise ratio. If you aren't able to go to a retailer that has the models you want to compare, try www.camcorderinfo.com. They give explicitly detailed reviews on cams from the ergonomics, features, to the picture quality with pics of resolution charts.

Answer 4

Cheap Crappy Device unless it has 3 CCD then it deserves to be called a Charged-Coupled device because then the quality is DVD ready especially with the bigger lens cameras like the Sony pro line or Canon GL-2. They represent semiconductors that are connected together in away that the output of one serves as the input of the other.

Answer 5

It's the camera's mojo.
