報を得ることを特徴とする画信号復号化装置。 It has a memory that receives coded data as an address input of a predetermined number of bits and outputs decoding information corresponding to the coded data, and is an image processor for decoding coded data encoded using the Modified Huffman (MH) method. In the signal decoding device, the memory has a bit number m smaller than the maximum bit number n of the code data as an input address, and outputs decoding information for the code data that can be decoded with m or less bits. In addition, for the code data exceeding m bits, information indicating the pattern type of the upper bit data of the data is output, and for the code data less than m bits, the data is read out from the memory by using the data as an address input. For code data exceeding m bits, the memory is accessed using the upper bits of the data to obtain the pattern type information of the upper bits, and the pattern type information and the remaining bits of the code data are addressed. An image signal decoding device characterized in that the image signal decoding device reads out the memory again as an input to obtain corresponding decoding information.
