Abstract: A camera parameter derivation apparatus for deriving camera parameters of a plurality of cameras for which conditions that the cameras be arranged at ideal positions that are set on a straight line at equal intervals and that directions of all arranged cameras be parallel to each other have been set includes an internal parameter derivation unit that derives internal parameter matrices of the cameras based on estimated internal parameter matrices for all cameras that are arranged at estimated positions while being oriented in estimated directions, a camera position derivation unit that derives ideal positions of the cameras that minimize the maximum of the distances between the estimated positions and the ideal positions, and a rotation matrix derivation unit that derives rotation matrices for correcting external parameters such that errors from parallel directions are equal to or less than a threshold value.

Abstract: Learning model data of a learning model that inputs original video data in which a background and a motion of a competitor are recorded, competitor mask video data in which an area surrounding the competitor is masked in each of a plurality of image frames included in the original video data, and background mask video data in which an area other than the area surrounding the competitor is masked in each of a plurality of image frames included in the original video data, in a case where the original video data is input, outputs a true value competition score that is an evaluation value for a competition of the competitor, in a case where the competitor mask video data is input, outputs an arbitrarily determined true value background score, and in a case where the background mask video data is input, outputs an arbitrarily determined true value competitor score is generated.

Abstract: Learning model data indicating a relationship between mask video data obtained by arbitrarily masking a part of a region surrounding a player in each of a plurality of image frames included in video data in which actions of the player are recorded, and a mask score obtained by weighting a true value score which is an evaluation value for a game of the player recorded in the video data according to a ratio of the masked region is generated.

Abstract: An image display device (1) according to the present disclosure includes an image display unit (2) that has a pixel structure of subpixels having a plurality of colors, in which the subpixels having different colors are aligned in a first direction, and the subpixels having the same color are aligned in a second direction perpendicular to the first direction and causes an observer ob to observe an image through a plurality of opening portions (24) disposed for each pixel block BL including a plurality of pixels including the subpixels having the plurality of colors. A width of each of the plurality of opening portions (24) in the first direction is substantially equal to a width of a subpixel of the subpixels in the first direction, and the plurality of opening portions (24) are disposed to be shifted in the first direction.
