ABSTRACT:
Disclosed are an image compression device for accurately compressing and reproducing a multi-spectral image, an image of a color space not dependent upon a device and lighting or a multi-primary-color image, and an image uncompression apparatus utilizing the same. An image compression device comprises a cluster storing section for storing a parameter for classifying image signals of an input image into a plurality of clusters, a cluster fixing section for fixing which cluster each of the inputted image signal belongs to that is stored in the cluster storing section; and a cluster-base image compressing section for performing a different image compression processes of image signal on a cluster-by-cluster basis. The image compression device thus configured can accurately compress and reproduce, at high compression ratio, a multi-spectral image, an image of a color space not dependent upon a device and lighting or a multi-primary-color image. Accordingly, when transmitting and receiving multi-dimensional images between remote locations, the data amount of transmission can be reduced for efficient transmission and reception.
