An active-pixel sensor (APS) is an image sensor where each picture element ("pixel") has a photodetector and an active amplifier.
In signal processing and related disciplines, aliasing is an effect that causes different signals to become indistinguishable (or aliases of one another) when sampled.
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.
Advanced Photo System type-C (APS-C) is an image sensor format approximately equivalent in size to the Advanced Photo System "classic" negatives of 25.1×16.7 mm, an aspect ratio of 3:2.
A Bayer filter mosaic is a color filter array (CFA) for arranging RGB color filters on a square grid of photosensors.
A charge-coupled device (CCD) is a device for the movement of electrical charge, usually from within the device to an area where the charge can be manipulated, for example conversion into a digital value.
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.
Complementary metal–oxide–semiconductor, abbreviated as CMOS, is a technology for constructing integrated circuits.
In photography, a color filter array (CFA), or color filter mosaic (CFM), is a mosaic of tiny color filters placed over the pixel sensors of an image sensor to capture color information.
A color space is a specific organization of colors.
Colorfulness, chroma and saturation are attributes of perceived color relating to chromatic intensity.
In digital photography, the CYGM filter is an alternative color filter array to the Bayer filter (GRGB).
A demosaicing (also de-mosaicing, demosaicking or debayering) algorithm is a digital image process used to reconstruct a full color image from the incomplete color samples output from an image sensor overlaid with a color filter array (CFA).
A digital camera or digicam is a camera that captures photographs in digital memory.
In computer science, Digital image processing is the use of computer algorithms to perform image processing on digital images.
A digital single-lens reflex camera (also called digital SLR or DSLR) is a digital camera that combines the optics and the mechanisms of a single-lens reflex camera with a digital imaging sensor, as opposed to photographic film.
Film speed is the measure of a photographic film's sensitivity to light, determined by sensitometry and measured on various numerical scales, the most recent being the ISO system.
In geometrical optics, a focus, also called an image point, is the point where light rays originating from a point on the object converge.
Foveon, Inc., is an American company that manufactures and distributes image sensor technology.
George Franklin Gilder (born November 29, 1939) is an American investor, writer, economist, techno-utopian advocate, and co-founder of the Discovery Institute.
In computer graphics and digital imaging, image scaling refers to the resizing of a digital image.
An image sensor or imaging sensor is a sensor that detects and conveys the information that constitutes an image.
"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.
The Kodak Professional DCS Pro SLR/n is a 13.5 megapixel (4500x3000 pixels) full-frame 35mm digital SLR produced as a collaboration between Nikon Corporation and Eastman Kodak.
A microlens is a small lens, generally with a diameter less than a millimetre (mm) and often as small as 10 micrometres (µm).
The micrometre (International spelling as used by the International Bureau of Weights and Measures; SI symbol: μm) or micrometer (American spelling), also commonly known as a micron, is an SI derived unit of length equaling (SI standard prefix "micro-".
In mathematics, physics, and art, a moiré pattern or moiré fringes are large-scale interference patterns that can be produced when an opaque ruled pattern with transparent gaps is overlaid on another similar pattern.
A photodiode is a semiconductor device that converts light into an electrical current.
In digital imaging, a pixel, pel, dots, or picture element is a physical point in a raster image, or the smallest addressable element in an all points addressable display device; so it is the smallest controllable element of a picture represented on the screen.
Polaroid is an American company that is a brand licensor and marketer of its portfolio of consumer electronics to companies that distribute consumer electronics and eyewear.
A set of primary colors is, most tangibly, a set of real colorants or colored lights that can be combined in varying amounts to produce a gamut of colors.
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.
A camera raw image file contains minimally processed data from the image sensor of either a digital camera, image scanner, or motion picture film scanner.
The RGB color model is an additive color model in which red, green and blue light are added together in various ways to reproduce a broad array of colors.
In digital photography, the RGBE filter is an alternative color filter array to the Bayer filter (GRGB).

The Sigma SD14 is a digital single-lens reflex camera produced by the Sigma Corporation of Japan.
The Sigma SD15 is an updated version of Sigma SD14 DSLR produced by the Sigma Corporation of Japan and featuring the improved TRUE II image processing engine, but with the same image sensor as its predecessor.
The Sigma SD9 is a digital SLR camera produced by the Sigma Corporation of Japan.
Spectral sensitivity is the relative efficiency of detection, of light or other signal, as a function of the frequency or wavelength of the signal.
A wafer, also called a slice or substrate, is a thin slice of semiconductor material, such as a crystalline silicon, used in electronics for the fabrication of integrated circuits and in photovoltaics for conventional, wafer-based solar cells.
In physics, the wavelength is the spatial period of a periodic wave—the distance over which the wave's shape repeats.
