PICTURE ENCODER AND PICTURE DECODER

摘要

A picture encoder receives the picture element data of high-resolution parts pictures. A high-order layer encoding section (101), a second shape data generating section (102), and a second shape data encoding section (103) encode the picture element data and shape data of high-order layers. A down-sampling section (104) generates low-resolution picture element data. A low-order layer encoding section (105), a first shape data generating section (106), and a first shape data encoding section (107) encode the picture element data and shape data of low-order layers.
