Effective pixels

Effective Pixels is a measurement of the number of pixels that actively record the photographic image within a sensor. As an example, a camera might hold a sensor containing 10.5 megapixels, but they have an effective pixel count of 10.2 megapixels. This discrepancy is due to the fact that digital imaging sensors have to dedicate a certain percentage of available pixels to establish a black reference point. These pixels are usually arranged frame-like, along the edge of the sensor, out of range of the recorded image.

Effective pixels

The actual numbers of pixels the camera s sensor uses to make the image. The number of effective pixels is often slightly smaller than the total number of pixels, as some pixels are not used in the actual making of the image.
