IMAGE DECODING DEVICE AND IMAGE CODING DEVICE

摘要

In view synthesis prediction, motion compensation has been performed in units of 4×4 blocks when the prediction block is AMP. Provided is an image decoding device (31) that generates and decodes a predicted image of a target prediction block, including a view synthesis predictor (3094, 3094′, 3094B, 3094B′) that generates a predicted image using view synthesis prediction. The view synthesis predictor partitions the prediction block into sub-blocks according to whether or not the height or the width of the prediction block is other than a multiple of 8, and derives a depth-derived disparity for each of the sub-blocks.

1. An image decoding device that generates and decodes a predicted image of a prediction block, comprising:
a view synthesis predictor that generates a disparity to use in view synthesis prediction, wherein the view synthesis predictor sets a sub-block size according to whether or not the height or the width of the prediction block is a multiple of 8, and uses the sub-block size to reference depth and derive a depth-derived disparity.
