Title:
VIDEO EVALUATION APPARATUS, METHOD, AND PROGRAM, AND SPATIO-TEMPORAL FREQUENCY ANALYZING APPARATUS, METHOD, AND PROGRAM
Document Type and Number:
Japanese Patent JP2007043655
Kind Code:
A
Abstract:
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.
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.
