Title:

IMAGE ENCODING AND DECODING METHOD AND IMAGE DECODING DEVICE

Document Type and Number:

WIPO Patent Application WO/2016/195453

Kind Code:

A1

Abstract:

Disclosed are an image encoding and decoding method and an image decoding device for selecting a prediction candidate from reference blocks of a reference picture, which includes a current picture, and using the selected prediction candidate so as to derive motion information on a current block during image encoding and decoding. The image encoding and decoding method comprises the steps of: configuring a spatial motion vector candidate; determining whether the reference picture of the current block exists within the current picture; and adding a spatial motion vector candidate in other block of the current picture encoded prior to the current block, if a determination result in the determination step is "yes".
