DYNAMIC IMAGE ENCODING DEVICE

摘要

An encoding circuit (1) encodes an input image. A thinning judgment unit (2) judges whether a pictures should be thinned. A dummy picture storage device (4) contains a dummy picture. The dummy picture is encoded data in which all the blocks reference the same picture, motion vectors of all the blocks are zero, and no block has prediction error information. A reference picture selection unit (5) selects a reference picture from the reference-enabled pictures. A header generation unit (7) generates a header to be attached to the dummy picture. In the header, the selected reference picture is allocated for an index instructing the reference picture of the dummy picture.
