IMAGE PROCESSING DEVICE AND METHOD

WIPO Patent Application WO/2019/049684

A1

This technology relates to an image processing device and method which enable improvement in the accuracy of motion compensation. This image processing device is provided with a prediction unit that performs first block matching using a reference image to derive the motion vector of a block to be processed, and derives the motion vectors of some of sub blocks constituting the block using second block matching different from the first block matching. This technology is applicable to an image coding device and an image decoding device.
