The '''fill factor''' of an [[image sensor]] array is the ratio of a pixel's light sensitive area to its total area. For pixels without [[microlens]]es, the fill factor is the ratio of [[photodiode]] area to total pixel area, but the use of microlenses increases the effective fill factor, often to nearly 100%, by converging light from the whole pixel area into the photodiode.
