摘要： PROBLEM TO BE SOLVED: To quickly decode a code word whose variable length encoding has been performed. SOLUTION: A variable length encoding/decoding device 10 is provided with a segmentation part 100 for segmenting a bit column from a bit stream; a storage part 111 for storing a code word including one coefficient and corresponding decoded data and code length; a storage part 121 for storing a code word including two or more coefficients and corresponding decoded data and code length; a judgement part 110 for judging whether or not the code word stored in the storage part 111 is included in the segmented bit column, and for outputting the decoded data and code length of the code word; and a judgement part 120 for judging whether or not the word code stored in the storage part 121 is included in the segmented bit column, and for outputting the decoded data and code length of the code word. The segmentation part 100 segments the bit column in the same cycle as the cycle in which judgement has been made by the judgement part 110, and segments the bit column in the cycle next to the cycle when the judgement has been made by the judgement part 120.

摘要： PROBLEM TO BE SOLVED: To provide an image decoder for carrying out proper error correction in accordance with error occurrence causes to thereby minimize a degradation in the image quality due to the error. SOLUTION: The image decoder decodes a code bit string resulting from coding blocks each composed of M×N sets of image data, wherein a count means 12 counts the number of data decoded by a decoding means 11, when the counted value is M×N or below and a code denoting a block border is detected, decode processing applied to a succeeding block is started in the case that the M×N-th decoding processing is finished, when the code denoting the block border is not detected even if the counted value reaches M×(N+1), the decoding processing is continued as it is, it is judged that the data up to the M×N-th data after decoding are valid data and the data of the M×(N+1)-th or over are invalid data, and only the valid data are outputted.

摘要翻译：要解决的问题：提供一种用于根据错误发生原因进行适当的纠错的图像解码器，从而最小化由于错误导致的图像质量的劣化。解决方案：图像解码器对由M×N组图像数据组成的编码块产生的码位串进行解码，其中计数装置12对由解码装置11解码的数据数进行计数，当计数值为 M×N以下，检测出代表块边界的代码，在M×N次解码处理结束的情况下，即使没有检测到表示块边界的代码，开始应用于后续块的解码处理如果计数值达到M×（N + 1），则解码处理继续进行，判断为高达解码后的M×N个数据的数据为有效数据，M×（ N + 1）以上是无效数据，仅输出有效数据。版权所有（C）2006，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To provide an image decoding apparatus for decoding variable length encoded image data at high speed while suppressing an increase in a circuit area. SOLUTION: Each of first-third decoding parts 100-300 is provided with a comparator, a decoder and a code word table. The code word table 130 has the MPEG code word table of "RUN=0", and the code word tables 230 and 330 have the MPEG code word table of "RUN≠0". In the first decoding part 100, the comparator 110 compares an input variable length code bit string with the variable length code word of the code word table 130, and the decoder 120 outputs a decoded result corresponding to a matching variable length code word to an output part 30. The second decoding part 200 and the third decoding part 300 decode two variable length code words in one machine cycle by utilizing a shift part 20. COPYRIGHT: (C)2007,JPO&INPIT
