An image distribution system using an image display system, the image display system containing: a head-mounted display (300, 300A, 300B) having a capturing part for obtaining first real-world video information by capturing a real world and an image display part for displaying first video obtained by integrating the first real-world video information captured by the capturing part with first virtual-world video information; a movement information detecting part (400, 400A, 400B) for detecting movement of a body of a wearer (P, P1, P2) wearing the head-mounted display (300, 300A, 300B) as movement information; a position information detecting part for detecting position information of the wearer (P, P1, P2); and a capturing device configured to capture a predetermined field in which the wearer (P, P1, P2) exists to obtain second real-world video information, the image distribution system characterized in that: the image distribution system is configured to distribute second video obtained by integrating the second real-world video information obtained by the capturing device with second virtual-world video information obtained by viewing the first virtual-world video information from a viewpoint of the capturing device which is different from a viewpoint of the wearer (P, P1, P2), the image display system is configured to control the first virtual-world video information and the second virtual-world video information based on the movement information and the position information, the position information detecting part is configured to obtain the position information of the wearer (P, P1, P2) by performing image recognition of a marker (200, 200A, 200B) arranged in a space using the capturing part of the head-mounted display (300, 300A, 300B), and the movement information detecting part (400, 400A, 400B) is configured to be worn on an arm of the wearer (P, P1, P2) and has an acceleration sensor for detecting an acceleration, an angular velocity sensor for detecting an angular velocity and a muscle potential sensor for detecting a muscle potential of the arm of the wearer (P, P1, P2). a head-mounted display (300, 300A, 300B) having a capturing part for obtaining first real-world video information by capturing a real world and an image display part for displaying first video obtained by integrating the first real-world video information captured by the capturing part with first virtual-world video information;
