ENCODING DEVICE, DECODING DEVICE, ENCODING METHOD, AND DECODING METHOD

摘要

This encoding method includes an index setting step, a prediction step, and an encoding step. In the index setting step, an index indicating weight coefficients and reference image information is set. In the prediction step, a reference value is derived as a predicted value, said reference value being a reference value for a weight coefficient when the change in pixel values between at least one reference image and a target image for encoding is no more than a specified standard. In the encoding step, the difference between the weight coefficient and the predicted value is encoded.
