applies the reference orientation information to an estimation target player that is included in the sport video and different from the specific player; and estimates an orientation of the estimation target player using the reference orientation, wherein information designating the joint positions of the specific player is generated based on user's input individually performed for at least a plurality of places of joints, and wherein information specifying the estimation target player is generated based on the user's input individually performed for a number of places fewer than a number of the plurality of places of joints. ### Claim 2 (depends on 1) The orientation estimation method according to claim 1, wherein the processor further estimates information about a color of the estimation target player, and information about a color of the joint positions positions of the specific player. ### Claim 3 (depends on 1) The orientation estimation method according to claim 1, wherein a sport of the sport video is a team competition sport, and the reference orientation information is information input for a player of each of at least two opposing teams. ### Claim 4 (depends on 3) The orientation estimation method according to claim 3, wherein the processor estimates the orientation of the estimation target player within a team among the at least two opposing teams using the reference orientation information for each team of the at least two opposing teams. ### Claim 5 (depends on 1) The orientation estimation method according to claim 1, wherein a sport of the sport video is a certain sport in which the specific player and the estimation target player wear prescribed uniforms for each team of the at least two opposing teams. ### Claim 6 (depends on 1) The orientation estimation method according to claim 1, wherein the processor specifies the estimation target player by information input from the user. ### Claim 7 An orientation estimation device, comprising: a processor, wherein the processor receives reference orientation information of a specific player included in the sport video, the reference orientation information designating a plurality of joint positions of the specific player, and applies the reference orientation information to an estimation target player that is included in the sport video and different from the specific player; and estimates an orientation of the estimation target player using the reference orientation information, wherein information designating the joint positions of the specific player is generated based on user's input individually performed for at least a plurality of places of joints, and wherein information specifying the estimation target player is generated based on the user's input individually performed for a number of places fewer than a number of the plurality of places of joints. ### Claim 8 (depends on 7) The orientation estimation device according to claim 7, wherein the processor further estimates information about a color of the estimation target player, and information about a color of the joint positions of the specific player. ### Claim 9 (depends on 7) The orientation estimation device according to claim 7, wherein a sport of the sport video is a team competition sport, and the reference orientation information is information input for a player of each of at least two opposing teams. ### Claim 10 (depends on 9) The orientation estimation device according to claim 9, wherein the processor estimates the orientation of the estimation target player within a team among the at least two opposing teams using the reference orientation information for each team of the at least two opposing teams. ### Claim 11 (depends on 7) The orientation estimation device according to claim 7, wherein a sport of the sport video is a certain sport in which the specific player and the estimation target player wear prescribed team uniforms for each team of the at least two opposing teams. ### Claim 12 (depends on 7) The orientation estimation device according to claim 7, wherein the processor specifies the estimation target player by information input through the input device from the user. ### Claim 13 (depends on 1) The orientation estimation method according to claim 1, wherein the joint positions include position includes any of positions of a head, a chest, a waist, a part above knee, and a part below knee of a player. ### Claim 14 (depends on 7) The orientation estimation device according to claim 7, wherein the joint positions include any of positions of a head, a chest, a waist, a part above knee, and a part below knee of a player.
