WIPO Patent Application WO/2014/168121
Kind Code:
A1
Abstract:
An image encoding device that, when encoding a multiview image comprising a plurality of images from different perspectives, uses a reference image from a different perspective from a target image being processed and a reference depth map for a subject in said reference image to encode while performing image prediction across different perspectives. Said image encoding device has the following: a combined-perspective-image generation unit that uses the aforementioned reference image and reference depth map to generate a combined-perspective image for the entire target image being encoded; a prediction-unit setting unit sets a prediction unit, i.e. sets whether to perform prediction for each encoding block into which the target image has been partitioned or to perform prediction on the entire target image using the aforementioned combined-perspective image; a prediction-unit-information encoding unit that encodes information indicating the aforementioned prediction unit; and a target-image predictive encoding unit that, if the prediction unit was selected such that prediction is performed per encoding block, performs predictive encoding on the target image while selecting a predicted-image generation method for each encoding block.
