<P>PROBLEM TO BE SOLVED: To provide an encoding device which, in the case of performing hierarchical encoding, is capable of encoding progressive data in a high-order layer and encoding interlaced image data in a low-order layer. <P>SOLUTION: A low-order layer encoding circuit 12 encodes interlaced image data S10_2 to generate low-order encoded data S12. A conversion circuit 13 applies interpolation (up-sampling) processing to low-order prediction image data L_PRE generated by the low-order layer encoding circuit 12 to generate low-order prediction image data L_PREb of the same resolution (the number of scanning lines) as that of the progressive image data S10_1. A high-order layer encoding circuit 14 encodes the progressive image data S10_1 on the basis of the low-order prediction image data L_PREb. <P>COPYRIGHT: (C)2013,JPO&INPIT |
