Title:
VIDEO ENCODING DEVICE, VIDEO ENCODING METHOD, AND VIDEO ENCODING PROGRAM, AND VIDEO DECODING DEVICE, VIDEO DECODING METHOD, AND VIDEO DECODING PROGRAM
Document Type and Number:
WIPO Patent Application WO/2012/090397
Kind Code:
A1
Abstract:
A video encoding device for encoding, in block units, each picture in a video using a motion vector, wherein a predicted motion vector candidate generator (120) generates a plurality of predicted motion vector candidates from the motion vector of an adjacent encoded block within the same picture as a block to be encoded and a block at the same position in another encoded picture, and presents an index representing the candidate. A predicted motion vector candidate deletion unit (122) calculates a difference motion vector from the candidates of the predicted motion vector and the motion vector of the block to be encoded, and deletes a predicted motion vector candidate on the basis of an encoding amount calculated from the difference motion vector and of the index of the predicted motion vector candidate. A predicted motion vector determining unit (123) selects a predicted motion vector from candidates remaining after deletion.
