摘要
An objective of the present invention is to make a video image frame into a hierarchical structure represented with a plurality of resolutions. With a zeroth layer (30), a first layer (32), a second layer (34), and a third layer (36) in order by increasing resolution, layer data which denotes a frame at a time (t1) treats the zeroth layer (30) and the second layer (34) as base image layers, and the first layer (32) and third layer (36) as difference image layers. In such a circumstance, when a region (124a) is displayed with the resolution of the third layer (36), an image of a corresponding region (126a) which the second layer (34) retains is enlarged to the resolution of the third layer (36) and each pixel value added to a difference image of a region (124a) which the third layer (36) retains. The layer which is treated as the difference image layer is switched with the passage of time (t2, t3, ...).
