Title: DECODING DEVICE, CODING DEVICE, DECODING METHOD AND CODING METHOD
Abstract:
An image decoding device (400A) is provided with a processor and a memory. Using the memory, the processor: acquires a plurality of motion vectors of a plurality of sub-blocks obtained by splitting a target frame (S231); on the basis of the plurality of motion vectors determines quantization control for each of a plurality of processing blocks obtained by splitting the target frame (S232); and subjects the plurality of processing blocks to inverse quantization using the determined quantization control (S233).
