Effective Pixels
Effective Pixels concerns the operation of a camera's CCD image sensor. A CCD is comprised of hundreds of thousands of tiny pixel elements which translate light to a visible video image. But effective pixels must be distinguished from total pixels. Of the total number of pixels contained on a CCD image chip, some are not used for video imaging whatsoever. The number of effective pixels indicates exactly how many of the pixels are actively at work to deliver video. A higher number of effective pixels tends to indicate a higher resolution camera, though this number may not always describe actual video quality in the important categories of sharpness, color saturation and vividness, as well as low light performance.
