摘要

A video processing device (100) is provided with an edge histogram generating unit (141) and a noise reduction processing unit (150). The generating unit (141) generates an edge histogram of a decoded image generated from a video signal, and the processing unit (150) determines, for the edge histogram, whether the ratio of a sum obtained by adding the frequency of levels higher than a predetermined level with respect to a sum total is equal to or greater than a predetermined threshold value, and performs smoothing processing on the decoded image at a smoothing strength adjusted on the basis of the determination result.
