Apparatus for processing image data, comprising means (26) for dividing an incoming image to a plurality of blocks or sections made up of a plurality of pixels, code book means (28) for storing a plurality of blocks or sections having different predetermined combinations of pixels, each of the combinations being associated with unique identifying data, means (26) for comparing each block or section of the image with the stored blocks or sections and identifying the combination of pixels from the code book means (28) which substantially matches (either exactly or to within a predetermined tolerance level) the combination of pixels in the block or section of the image, and means (26) for outputting the identifying data (34) associated with the matching combination. Apparatus is also provided for receiving and decoding image data, comprising means for receiving unique identifying data corresponding to combinations of pixels making up an image, code book or memory means for storing a plurality of blocks or sections having different predetermined combinations of pixels and the identifying data corresponding to each combination, means for comparing the incoming identifying data with the identifying data stored in the code book-means, means for identifying the pixel block or section to which the data corresponds, and means for outputting the respective pixel block or section. |
