WEIGHTED PREDICTION INFORMATION CALCULATION METHOD, DEVICE, PROGRAM, DYNAMIC IMAGE ENCODING METHOD, DEVICE, AND PROGRAM

摘要

A weighting factor calculation unit (1903) calculates a weighting factor using characteristics respectively corresponding to a picture to be predicted and a selected reference picture in accordance with a weighting factor equation derived from a fade effect generation principle. For each picture, an intra-picture characteristic calculation unit (1901) calculates the characteristics as characteristics closed in the picture. The weighting factor of a fade picture can be obtained with a small calculation amount at high accuracy.
