Abstract
Official abstract text for this publication.
An image encoding device include a predicting unit for adaptively determining the size of each motion prediction unit block according to color component signals, and for dividing each motion prediction unit block into motion, vector allocation regions to search for a motion vector, and a variable length encoding unit for, when a motion vector is allocated to the whole of each motion prediction unit block, performing encoding in mc_skip mode if the motion vector is equal to an estimated vector and a prediction error signal does not exist, and for, when each motion vector allocation region has a size equal to or larger than a predetermined size and a motion vector is allocated to the whole of each motion vector allocation region, performing encoding in sub_mc_skip mode if the motion vector is equal to an estimated vector and a prediction error signal does not exist.
First claim
Opening claim text (preview).
The invention claimed is: 1. An image decoding device which decodes a predictive-encoded hit stream to acquire a moving image signal, the bit stream being created by dividing each frame of the sieving image signal into a plurality of blocks and by performing a motion prediction for each of the blocks, the image decoding device comprising: a decoding unit for decoding the bit scream to acquire information indicating a size of the block, information indicating a threshold on a block…
