In estimating subjective video quality corresponding to main parameters () which are input as an input coding bit rate (B/B) representing the number of coding bit rates per unit time and an input frame rate (A/A) representing the number of frames per unit time of an audiovisual medium, an estimation model specifying unit specifies, on the basis of the input coding bit rate (B/input frame rate (A)), an estimation model () representing the relationship between subjective video quality and the frame rate (/coding bit rate) of the audiovisual medium. Subjective video quality corresponding to the input frame rate (A/input coding bit rateB) is estimated by using the specified estimation model () and output as an estimation value ().
