A video quality evaluation apparatus for evaluating a video quality that a user experiences for a service in which a 3D video is used, the video quality evaluation apparatus comprising: a 2D video quality derivation unit configured to derive, from input 3D video data, a left eye video quality that is a quality of a left eye video that is included in the 3D video data and a right eye video quality that is a quality of a right eye video that is included in the 3D video data; and a 3D video quality derivation unit configured to derive a quality of the 3D video from the left eye video quality and the right eye video quality; characterized by the 3D video quality derivation unit including: a base video quality determination unit configured to determine the higher one of the left eye video quality and the right eye video quality to be a base video quality, and to determine the lower one of them to be a sub-video quality; the 3D video quality derivation unit including: a 3D video calculation unit configured to set a model equation representing a relationship between the base video quality, the sub-video quality and the 3D video quality, and to calculate a value of the 3D video quality from the base video quality and the sub-video quality based on the model equation; the model equation being such that the 3D video quality is based on the base video quality but gradually falls the greater the difference between the base video quality and the sub-video quality or the smaller the ratio between the base video quality and the sub-video quality is. a 2D video quality derivation unit configured to derive, from input 3D video data, a left eye video quality that is a quality of a left eye video that is included in the 3D video data and a right eye video quality that is a quality of a right eye video that is included in the 3D video data; and a 3D video quality derivation unit configured to derive a quality of the 3D video from the left eye video quality and the right eye video quality; characterized by the 3D video quality derivation unit including: a base video quality determination unit configured to determine the higher one of the left eye video quality and the right eye video quality to be a base video quality, and to determine the lower one of them to be a sub-video quality; the 3D video quality derivation unit including: a 3D video calculation unit configured to set a model equation representing a relationship between the base video quality, the sub-video quality and the 3D video quality, and to calculate a value of the 3D video quality from the base video quality and the sub-video quality based on the model equation; the model equation being such that the 3D video quality is based on the base video quality but gradually falls the greater the difference between the base video quality and the sub-video quality or the smaller the ratio between the base video quality and the sub-video quality is. a base video quality determination unit configured to determine the higher one of the left eye video quality and the right eye video quality to be a base video quality, and to determine the lower one of them to be a sub-video quality; the 3D video quality derivation unit including: a 3D video calculation unit configured to set a model equation representing a relationship between the base video quality, the sub-video quality and the 3D video quality, and to calculate a value of the 3D video quality from the base video quality and the sub-video quality based on the model equation; the model equation being such that the 3D video quality is based on the base video quality but gradually falls the greater the difference between the base video quality and the sub-video quality or the smaller the ratio between the base video quality and the sub-video quality is. a 3D video calculation unit configured to set a model equation representing a relationship between the base video quality, the sub-video quality and the 3D video quality, and to calculate a value of the 3D video quality from the base video quality and the sub-video quality based on the model equation; the model equation being such that the 3D video quality is based on the base video quality but gradually falls the greater the difference between the base video quality and the sub-video quality or the smaller the ratio between the base video quality and the sub-video quality is.
