VIDEO QUALITY OBJECTIVE EVALUATION DEVICE, EVALUATION METHOD, AND PROGRAM

摘要

A video quality objective evaluation device includes: a temporal/spatial characteristic deriving unit (12) for deriving a temporal/spatial characteristic amount (PC) which is a deterioration characteristic generated in a deteriorated video signal (PI), from the deteriorated video signal (PI) to be evaluated and a reference video signal (RI) which is a signal before deterioration of the deteriorated video signal; and a subjective quality estimation unit (14) for weighting the temporal/spatial characteristic amount (PC) according to the relationship between the pre-acquired deteriorated vide and the user subjective evaluation value, thereby estimating the subjective quality Y of the deteriorated video signal (PI). Thus, it is possible to estimate a video subjective quality even when deterioration is caused locally in the temporal/spatial direction in the video.
