Abstract
Official abstract text for this publication.
The present invention compensates motion at high precision even for an image having different characteristics in the horizontal direction and vertical direction, while decreasing code quantity of filter coefficients when a reference image with the fractional image accuracy is generated using a filter of each frame and is encoded and decoded with compensating motion.
First claim
Opening claim text (preview).
What is claimed is: 1. A video encoding device which creates a reference frame image with a fractional pixel accuracy and compensates a motion for a video image formed of a time series of frame images, by using a filter for each frame image, comprising: a filter information storage unit that stores, in relation to a past frame image, a past filter which has been used for encoding of the past frame image; a filter decision unit responsive to receipt of a set of multiple candidate…
