EXPEED
The Nikon Expeed /video processors (often styled EXPEED) are media processors for Nikon's digital cameras. They perform a large number of tasks: Bayer filtering, demosaicing, corrections/dark-frame subtraction, reduction, image sharpening, , gamma correction, image enhancement/Active D-Lighting, colorspace conversion, chroma subsampling, framerate conversion, /chromatic aberration correction, /JPEG encoding, video compression, display/video interface driving, , face detection, audio processing/compression/encoding and computer data storage/data transmission.
Fujitsu FR
The Fujitsu FR (Fujitsu RISC) is a 32-bit RISC processor family. New variants include a floating point unit and partly video input analog-to-digital converter and digital signal processor. It is supported by Softune, GNU Compiler Collection and other integrated development environments. Fujitsu FR are used to control previous versions of Milbeaut signal processors specialized for . Although variants of the 6th generation in 2011 and later generations changed to dual-core ARM architecture, ASSP/ASIC variants with FR controller are continued.
Media processor
A media processor, mostly used as an /video processor, is a microprocessor-based system-on-a-chip which is designed to deal with digital streaming data in real-time (e.g. display refresh) rates. These devices can also be considered a class of digital signal processors (DSPs). Unlike graphics processing units (GPUs), which are used for computer displays, media processors are targeted at digital televisions and set-top boxes. The streaming digital media classes include: uncompressed video compressed digital video - e.
Processeur d'images
Le processeur d'images est un composant important d'un appareil photographique numérique qui joue un rôle essentiel dans la création de l'. Le processeur d'images doit réaliser plusieurs tâches complexes. Les photodiodes présentes dans un capteur photographique sont monochromes par nature : elles peuvent seulement enregistrer différents niveaux de gris. Pour obtenir une image en couleurs, elles sont recouvertes par trois filtres colorés : rouge, vert et bleu (RGB) selon un arrangement appelé filtre de Bayer - d'après le nom de son inventeur.
