<p><P>PROBLEM TO BE SOLVED: To create a prediction video signal which has high correlation with an original video image signal by appropriately carrying out high resolution processing of a basic decoded video image signal which is decoded basic coding data, and achieve a more efficient video image hierarchy encoding. <P>SOLUTION: A video image hierarchy encoding apparatus 100 is provided with: a high pass filtering unit 208 which separates a high frequency component from the basic decoded video image signal, and creates a high frequency separation signal in a pre-stage of prediction processing between hierarchies when spacial interpolation is carried out from a basic layer to an extension layer; and a high frequency extraction filtering unit 210 which extracts the high frequency component corresponding to the original video image signal from the high frequency separation signal, and creates a high frequency equivalent signal. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
