ABSTRACT:
Coded image data which are coded hierarchically are decoded successively by an inverse wavelet transformer. During a process of decoding, images of intermediate hierarchy are stored in a frame buffer. In a case where constrains are placed on memory capacity or power capacity utilizable for a decoding processing, or resolution at an outputting end is limited, an abort processor discontinues or aborts the decoding processing in the middle. Then, the abort processor extracts intermediate-hierarchy images obtained by that time, from the frame buffer, and performs thereon an image processing such as a scaling, as appropriate, so as to be used as final decoded images. Thereby, a processing cost is markedly reduced.
