<p><P>PROBLEM TO BE SOLVED: To provide a high-efficiency encoding technique having high versatility without requiring preprocessing for setting a background image. <P>SOLUTION: An image processing apparatus has a moving image inputting means (2101) for inputting a moving image consisting of a plurality of frames; an image selecting means (101) for selecting a frame to be a background, irrespective of the presence or absence of an object in an image in selecting the frame to be the background image from among the moving images; a shape data generating means (103) for comparing the frame to be the background image with a frame of an input image, and generating shape data on the basis of the difference value; a background data correcting means (104) for correcting the background image on the basis of the shape data; and an arbitrary shape image encoding means (2105) for encoding the input image as an arbitrary shape image together with the shape image. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
