IMAGE PROCESSING DEVICE AND IMAGE PROCESSING METHOD

摘要

Encoding efficiency in multi-view image encoding is to be increased. A feature amount generation unit (41) generates a feature amount indicating the correlation between images of different viewpoints. Based on the generated feature amount, a reference index assignment unit (45) assigns reference indexes to a reference picture of a parallax prediction that uses the correlation between images of different viewpoints, and to a reference picture of a temporal prediction that uses the correlation between images in the temporal direction. In a case where the correlation is determined to be lower than a predetermined threshold value based on the feature amount, for example, the reference index assignment is changed, and the reference index assigned to a reference picture of a parallax prediction is re-assigned to a reference picture of a temporal prediction.
