摘要

A moving picture frame is made to have a hierarchical structure representing a plurality of resolutions. Assuming that the resolution is large in order of the 0th layer 30, the first layer 32, the second layer 34 and the third layer 36, in the layer data indicating the frame at the time t1, And the second hierarchy 34 as the original image hierarchy and the first hierarchy 32 and the third hierarchy 36 as the differential image hierarchy. In this case, when the area 124a is displayed with the resolution of the third hierarchy 36, the corresponding image of the area 124a held by the third hierarchy 36 corresponds to the correspondence maintained by the second hierarchy 34 The image of the area 126a is enlarged up to the resolution of the third layer 36 and each pixel value is added. The layer to be the difference image layer is switched with the passage of time t2, t3, ....
