Active pixel sensor

An active-pixel sensor (APS) is an image sensor where each picture element ("pixel") has a photodetector and an active amplifier.

Aliasing

In signal processing and related disciplines, aliasing is an effect that causes different signals to become indistinguishable (or aliases of one another) when sampled.

Anti-aliasing filter

An anti-aliasing filter (AAF) is a filter used before a signal sampler to restrict the bandwidth of a signal to approximately or completely satisfy the sampling theorem over the band of interest.

Chromatic aberration

In optics, chromatic aberration (abbreviated CA; also called chromatic distortion and spherochromatism) is an effect resulting from dispersion in which there is a failure of a lens to focus all colors to the same convergence point.

Jaggies

"Jaggies" is the informal name for artifacts in raster images, most frequently from aliasing, which in turn is often caused by non-linear mixing effects producing high-frequency components or missing or poor anti-aliasing filtering prior to sampling.

Prime lens

In film and photography, a prime lens is a fixed focal length photographic lens (as opposed to a zoom lens, typically with a maximum aperture from f2.8 to f1.2. The term can also mean the primary lens in a combination lens system. Confusion between these two meanings can occur if context doesn't make the interpretation clear. People sometimes use alternate terms—primary focal length, fixed focal length, or FFL to avoid ambiguity.
