"video prediction coding device, video prediction coding method, video prediction coding program, video prediction decoding device, video prediction decoding method and video decoding program" video prediction ". It's about improved bipreview performance with fewer encoding bits. a predicted signal generation unit (103) provided in a video predictive coding device includes: a means (122) that estimates number zero motion vector, selects number zero motion vector predictor similar to number zero motion vector, generates secondary information number zero containing motion vector predictor index number zero; means (121) that selects a motion vector having a high correlation with the target region, which generates first secondary information that contains first motion vector predictor index to identify motion vector as the first motion vector predictor and which sets the first motion vector predictor to first motion vector; and means (123) combining the predicted signal number zero and the first predicted signal to generate a predicted signal from the target region.
