ENCODING DEVICE, DECODING DEVICE, ENCODING METHOD AND DECODING METHOD Russian patent published in 2017 - IPC G06T9/00 H04N19/61 

FIELD: physics.

SUBSTANCE: encoding method includes an index setting step, a prediction step, and an encoding step. The index setting stage sets an index that represents information of the reference image and the weighting factor. The prediction step predicts in this manner that the weight reference value when the change in the pixel value between, at least, one reference image and the target image to be encoded is a specific support or less, is output as a predicted value. The encoding step encodes the difference value between the weighted and predicted values.

EFFECT: increasing the information encoding efficiency.
