Subjective quality estimating part (11), input deteriorated video signal to the reference video signal is degraded reference video signal is a video signal does not deteriorate with (RI) and (PI), the video signal feature values ​​of both the signal Based on the difference between the video signal feature values ​​of both signals is calculated, the calculated, to estimate the subjective quality of the deteriorated video signal. The feature amount calculation unit (12) calculates the video signal feature amount of the reference video signal. Correction information storage unit (13), correction information for correcting the subjective quality, are stored corresponding to the video signal feature value. Correction calculation section (14), and obtains the correction information storing part (13), the correction information corresponding to the video signal feature values ​​of the reference video signal input feature value calculating part (12), the correction unit (15) pass. Correction unit (15) corrects the subjective quality of the deteriorated video signal on the basis of the correction information that is passed, the estimated subjective quality estimating part (11).
