摘要： An input image is divided into blocks each represented by n.times.n matrix X, and then X.sup.T X is calculated. Singular values of X that are positive square roots of eigenvalues of X.sup.T X and first singular vectors that are normalized eigenvectors of X.sup.T X are calculated by, for instance, the Jacobi method. Second singular vectors that are normalized eigenvectors of XX.sup.T are calculated analytically using the singular values and the first singular vectors. The singular values and the first and second singular vectors thus calculated are coded.

摘要： An image coding apparatus wherein an image signal including a locally high signal can be coded efficiently with minimized distortion by adaptively performing quantization for each subblock. An input image signal is divided into a plurality of subband signals by a subband division section. The subband signals from the subband division section are each divided into a plurality of subblocks by a subblock division section. In a classification section, a subband signal is classified, for each of the subblocks from the subblock division section, in terms of a feature parameter of an image, for example, a dynamic range, and a class index is outputted. In a quantization section, a quantizer is changed over for each subblock in response to the class index from the classification section. Each subblock is coded with a necessary minimum number of bits. The bit number is multiplexed with a code. Accordingly, the code can be decoded by referring to the bit number.

When it is judged that the input image block corresponds to the monochromatic information, the color difference component is not transferred or not stored. Only when it is judged that the input image block corresponds to the color information, the color difference component is transferred, or stored.
