In estimating subjective video quality corresponding to main parameters (121/221) which are input as an input coding bit rate (121B/221B) representing the number of coding bit rates per unit time and an input frame rate (121A/221A) 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 (121B/input frame rate (221A)), an estimation model (122/222) 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 (121A/input coding bit rate 221B) is estimated by using the specified estimation model (122/222) and output as an estimation value (123/223).
