IMAGE ENCODING DEVICE AND IMAGE DECODING DEVICE

摘要

PROBLEM TO BE SOLVED: To perform highly functional and efficient encoding by a small scale of hardware configuration by realizing the decoding of a plurality of resolutions and management with a tile through the use of wavelet transformation. SOLUTION: Management information for independently decoding an arbitrary tile by sub-band unit comprises information for indicating the storage position of encoding information corresponding to each tile or each sub-band and information for managing and identifying each tile or each sub-band. Then a bit stream is generated, where sub-band information of each tile are collected by same resolution unit.
