Abstract
An image processing apparatus is provided which can shape codes and omit buffers at a decoding side as well as omit an image memory at an encoding side by providing code buffers for respective encoders. An image encoding apparatus for encoding image information in a hierarchical form includes encoders provided for respective hierarchies and code buffers provided after the respective encoders. Furthermore, it is possible to use a common code buffer memory for respective hierarchies at the encoding side. In such a case, by arranging so that a hierarchical tag can identify to which hierarchy a code belongs, a simplified encoding apparatus is provided.
