ABSTRACT:
Hierarchical encoding techniques allowing a good compression efficiency and allowing to quickly recognize the outline of an image from a fraction of encoded data. In order to realize such techniques, an image processing apparatus has a generating unit for generating a plurality of coefficients representative of an image, a variable length encoding unit for encoding each of the plurality of coefficients generated by the generating unit, and a hierarchical output unit for distributing each bit of variable length encoded data corresponding to each coefficient and obtained through variable length encoding by the variable length encoding unit, to a plurality of bit planes each corresponding to a level of each bit, and hierarchically and sequentially outputting the plurality of bit planes.
