Abstract
An encoding device that performs encoding on each of blocks obtained by dividing an image includes: a weighted bi-predictorconfigured to generate a prediction block of an encoding-target block by weighted-averaging a plurality of reference images using weighted coefficients selected from a weighted coefficient set including a plurality of weighted coefficients; and a filter controllerconfigured to control deblocking filter based on the weighted coefficients applied by the weighted bi-predictorto each of the two blocks adjacent blocks.
