Abstract
An object is to provide a video evaluation apparatus and video evaluation method capable of appropriately evaluating a video consisting of a plurality of frame images, using an objective standard. The object is achieved as follows. A reference characteristic, which is a predetermined spatio-temporal frequency characteristic about a video, is stored, and a video characteristic analyzer 101 calculates a spatio-temporal frequency characteristic of a target video consisting of a plurality of frame images. Then a video evaluation determiner 102 calculates an evaluated value of the target video, based on a relative relation between the calculated spatio-temporal frequency characteristic and the stored reference characteristic. This enables appropriate evaluation of the video.
