Abstract:
1. An image recognition system that recognizes motions of players of a sport playing between areas partitioned by an obstacle such as a net from a content of its on-air program, of its material video before broadcasted, or recorded by a recording media such as a VTR, and characterized by comprising a visual information obtaining device that obtains visual information on which a motion of the player in at least one area during a match is shown from the content, an occlusion state determining device that determines whether or not a used material such as a ball that moves between the areas included in the visual information obtained by the visual information obtaining device and that is an object to count the score of the relevant sport is in a state being hidden by a predetermined object body, an impact time information specifying device that specifies an impact time when the used material is hit based on an occlusion start time when the occlusion state determining device determines that the used material changes its state from not being hidden by the object body to being hidden by the object and an occlusion release time when the occlusion state determining device determines that the used material changes its state from being hidden by the object body to not being hidden by the object, a rule information storing device that stores rule information to conduct the relevant sport, and an image content recognizing device that recognizes an image content including the motion of the player shown by the visual information based on the visual information obtained by the visual information obtaining device, a position of the used material at the impact time specified by the impact time information specifying device and the rule information stored in the rule information storing device.
