摘要： A variable-length code decoder includes plural barrel shifters, each of which executes shift processing on inputted variable-length code data bit by bit from the 0 bit to (the bit number of a maximum length codeword -1). The barrel shifters, which are in number equal to the bit number of the maximum length codeword, are arranged in parallel connection. Plural storing devices are provided, each of which stores a pair of a decoded symbol and codeword length thereof corresponding to code data. Plural fetching devices are provided, each of which fetches the pair of the decoded symbol and the codeword length thereof in accordance with the code data outputted from each of the barrel shifters. Each of the fetching devices is connected to a respective barrel shifter and storing devices. A selecting device is provided for selecting a predetermined pair from plural pairs of the decoded symbol and the codeword length fetched by the plural fetching devices in an initial decoding process. The selecting device further selects any one pair from the plural pairs of the decoded symbol and the codeword length utilizing the codeword length selected in the initial decoding process in subsequent decoding processes.

摘要： The present invention aims to execute effective compression even in the case where inputted image information has the bit number smaller than that of a pixel value, such as a tag, and besides in the case where the entropy increases if a prediction error obtained by subtraction of a value of a neighboring pixel from that of an object pixel is used for calculation of the entropy.According to the present invention, in an image encoding apparatus, the inputted image information is made to be packed image data of a fixed length and provided to a couple of predicting elements and a couple of prediction error calculating elements. The packed image data and prediction errors outputted from the couple of prediction error calculating elements are provided to a prediction error selecting element and one of the data and prediction errors having a smallest entropy is selected. A selecting element outputs an identification number of one of the predicting elements which succeeds in prediction, and if the predicting elements fail in prediction, the selecting element outputs the data or prediction error selected by the prediction error selecting element. The output from the selecting element is encoded by an encoding element to Huffman code, for example

摘要： A coding apparatus includes a predicting unit, an intermediate-code generating unit, a first coding unit and a second coding unit. The predicting unit generates a piece of prediction data based on each piece of pixel data constituting a color image. The intermediate-code generating unit compares each piece of prediction data with the corresponding piece of pixel data, to generate an intermediate code in accordance with whether or not a difference between each piece of prediction data and the corresponding piece of pixel data is in a predetermined range. The first coding unit performs entropy coding on the generated intermediate code. The second coding unit performs entropy coding on the generated intermediate code. The intermediate-code generating unit assigns each generated intermediate code to either of the first and second coding units according to whether or not the difference is in the predetermined range.
