Image processor

By adjusting the gamma value (heightening or lowering the contrast range of an image's mid-tones), subtle tonal gradations, such as in human skin or the blue of the sky, become much more realistic.

When higher ISO settings are chosen the electronic signal in the image sensor is amplified, which at the same time increases the noise level, leading to a lower signal-to-noise ratio.

Image processor users are using industry standard products, application-specific standard products (ASSP) or even application-specific integrated circuits (ASIC) with trade names: Canon's is called DIGIC, Nikon's Expeed, Olympus' TruePic, Panasonic's Venus Engine and Sony's Bionz.

Some are known to be based on the Fujitsu Milbeaut, the Texas Instruments OMAP, Panasonic MN103, Zoran Coach, Altek Sunny or Sanyo image/video processors.

ARM architecture processors with its NEON SIMD Media Processing Engines (MPE) are often used in mobile phones.
