Abstract:
According to an embodiment, an encoding device includes: an index setting unit sets an index that represents information of a reference image and a weighting factor; an index reconfiguring unit predicts a reference value of the weighting factor, wherein the reference value indicates a factor to be set if a difference of pixel value between a reference image and a target image to be encoded is less than or equal to a specific value; and an entropy encoding unit encodes a difference value between the weighting factor and the reference value.
