Effective pixels
|
|
The number of effective pixels that an image sensor has is the count of elementary pixel sensors that contribute to the final image, as opposed to the number of total pixels, which includes unused or light-shielded pixels around the edges. The terminology and definition of effective pixels and total pixels derives from Japanese camera-industry standards and is now incorporated in American national (ANSI) standards.
