Abstract: The image processing device comprises: a position identification section for identifying positions of two reference points and a position of physical characteristic point of the subject in the moving image; an angle acquisition section for obtaining an angle of a line segment connecting the two reference points with respect to the image plane; a conversion ratio calculation section for calculating a conversion ratio indicating a ratio between the length in the moving image and the length in real space; and a coordinate calculation section for calculating position coordinates of at least one of: the two reference points and the physical characteristic point of the subject in the image plane in the real space, based on the calculated conversion ratio and at least one of: the identified positions of the two reference points and the identified position of the physical characteristic point of the subject.

Abstract: An information processing apparatus includes an acquisition unit configured to acquire a video of a swing of a golfer who strikes a golf ball with a golf club, a calculation unit configured to calculates a feature amount of the swing from the video, and a conversion unit configured to convert the feature amount into an estimated value of a behavior of a golf club head by substituting the feature amount into a conversion formula.

Abstract: An apparatus includes an acquisition unit configured to acquire a measurement result of a golf swing motion, and a calculation unit configured to calculate a behavior of a shot by the golf swing motion. The measurement result includes a head speed, an incident angle, and a face angle at the time of striking. The behavior includes an initial speed, a vertical launch angle, and a back spin amount. The calculation unit calculates the behavior by substituting the head speed, the incident angle, and the face angle, all of which have been acquired by the acquisition unit, into a predetermined arithmetic formula having a plurality of variables including at least a head speed, an incident angle, and a face angle at the time of striking of a golf club head.

Abstract: A video processing apparatus is provided. The video processing apparatus includes: an inputter inputting video signals of a plurality of systems, and a processor generating processed video signals by performing switching on the video signals of two or more systems input into the inputter. Further, the video processing apparatus includes: a time code generator generating a time code, and a time code adder adding the time code to the input video signals and the generated video signals respectively, outputs the video signals with the time code to be recorded in a recording medium.
