摘要：
An image coding apparatus inputs pixel data of a part image of high resolution. An upper layer coding portion (101), a second shape data generating portion (102), and a second shape data coding portion (103) perform coding of shape data and pixel data in the upper layer. A down sampling portion (104) generates pixel data of low resolution. A lower layer coding portion (105), a first shape data generating portion (106), and a first shape data coding portion (107) code shape data and pixel data in the lower layer.
