Title:
PREDICTION DEVICE, PREDICTION METHOD AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2020/105576
Kind Code:
A1
Abstract:
This prediction device, for predicting a motion vector of an encoding target block when encoding a composite image obtained by synthesizing a multiview image into a single image, is provided with: a storage unit which stores a first predicted motion vector that indicates a candidate of a predicted motion vector; and an update unit which, if a prescribed condition is satisfied, generates, and stores in the storage unit, a second predicted motion vector which is a vector that indicates a pixel in the same position as the aforementioned encoding target block at an adjacent viewpoint.
