ABSTRACT:
An image signal encoding device which includes a code transforming unit. The code transforming unit includes a separation unit which separates mode information from first code data, a locally decoding unit which locally decodes the first code data using a decoding operation corresponding to the mode information and outputs locally decoded pixel block, and a second encoding unit which encodes the locally decoded pixel block using an encoding operation corresponding to the mode information and outputs second code data. According to the image signal encoding device, the first code data is re-encoded into the second code data having a higher compressibility so as to perform efficient data transmission and storage.
