Title:
IMAGE DECODING METHOD
Document Type and Number:
Japanese Patent JP2016158306
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an image coding technique to reduce a code amount.SOLUTION: In inter-prediction for performing motion search by using blocks divided from an input image and a reference image, a method includes selecting a motion vector of the block from the motion vectors of surrounding blocks to predict the motion vector; and calculating a differential vector to code the motion vector. In the above method, adaptive and efficient compression of a moving image is performed by varying the number or the positions of candidate blocks to select a prediction vector on the basis of a block unit or a frame unit.SELECTED DRAWING: Figure 1
