    摘要： Disclosed herein are easy-to-realize multivalued image coding and decoding devices, each of which is capable of reducing memories in number while the accuracy of calculations necessary upon coding and decoding is being held and relaxing a probability estimate. An image disassembler disassembles a bit string indicative of pixels into a plurality of parts in response to image data inputted from an image input unit. Further, the image disassembler sends the value of each disassembled pixel to be coded and the value of each disassembled pixel for reference to an image analyzer as disassembled image data. The image analyzer sends the value of each disassembled pixel to be coded to a coding unit as disassembled pixel-value data and transmits the value of the reference pixel to a probability estimate unit as status data. The probability estimate unit sends probability estimate data corresponding to the status data to the coding unit. The coding unit creates a codeword for each disassembled part from the probability estimate data and the disassembled pixel-value data and sends it to a code output unit as coded data.

    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.
