Abstract
A Huffman decoding unit includes: a code analysis unit configured to analyze compressed image data in encoded data sequentially received, and sequentially recognize zero run information, group number information, and additional bit information; and a frequency conversion unit configured to generate coefficient information based on the recognized zero run information, group number information and additional bit information. The code analysis unit receives the encoded data sequentially received and cutout information for cutting out a partial image from an entire image that is decodable based on the compressed image data. When the cutout information is received, only in a case where the compressed image data sequentially received is compressed image data intended for cutout, the code analysis unit outputs, to the frequency conversion unit, the zero run information, the group number information, and the additional bit information, each of which is recognized by analyzing the compressed image data.
