The Nikon Expeed image/video processors are media processors for Nikon's digital cameras. They perform a large number of tasks: Bayer filtering, demosaicing, image sensor corrections/dark-frame subtraction, image noise reduction, image sharpening, image scaling, gamma correction, image enhancement/Active D-Lighting, colorspace conversion, chroma subsampling, framerate conversion, lens distortion/chromatic aberration correction, image compression/JPEG encoding, video compression, display/video interface driving, digital image editing, face detection, audio processing/compression/encoding and computer data storage/data transmission.

Example of a Group Of Pictures showing I-, P- and the B-frames additionally used by the Expeed 2 and higher for MPEG encoding. "All-I" has no P- and B-frames similar to Motion JPEG: Frames are separately processed, lowering redundancy detection and compression.
