Title: Method and apparatus for compression and decompression of digital color images
Inventor: MARTINEZ-URIEGAS EUGENIO
IPC: H03M7/30
Filed: 1994-07-25
Abstract: Color image compression and decompression is achieved by either spatially or chromatically multiplexing three digitized color planes, into a digital array representative of a single digitized spatially- and chromatically-multiplexed plane, or, by use of a color imaging device. capturing an image directly into a single spatially-multiplexed image plane, for further compression, transmission and/or storage (40). At the point of decompression, a demultiplexer (50) separately extracts, from the stored or transmitted image, data to restore each of the color planes. Specific demultiplexing techniques involve correlating information of other planes with the color plane to be demultiplexed. Various techniques of entropy reduction, smoothing and speckle reduction may be used together with standard digital color compression techniques, such as JPEG. Using lossless JPEG about 6:1 data compression is achieved with no losses in subsequent processing after initial compression. Using lossy JPEG substantially higher data compression is achievable, but with proportional loss in perceived image quality.

Abstract: On peut utiliser un système à accès multiple par code de répartition orthogonale (AMDCO) qui présente une bande passante efficace dans un environnement à trajets multiples (10, 11-2 et 11-1). Le  code de pseudo-bruit à débit élevé atténue fortement les composantes à trajets multiples qui sont suffisamment retardées pour obtenir une incidence significative sur le degré d'orthogonalité réalisable. En décalant les porteuses de la valeur du débit de "chip" RW et un recourant à une synchronisation précise du réseau pour aligner tous les accès sur une petite fraction d'une durée de "chip" de code de pseudo-bruit à débit élevé, on peut utiliser pleinement la bande passante disponible. La procédure qui permet d'aligner cette base de temps est déjà décrite dans la demande de brevet des Etats-Unis portant le numéro de série 980,957.
