It is represented.

  In the present embodiment, the stadium is an indoor athletic stadium, and the run-up lane JL and the crossing line TO are installed on the ground. Competitor H5 runs along the runway AL and jumps from the crossing line TO.

  When a predetermined operation is performed, the image supply device 100C outputs the image data of the recording line RL2 to the projector 200 via the cable CB. The projector 200 projects the image of the recording line RL2 on the sandbox SD based on the input image data of the recording line RL2. The projector 200 is installed on the ceiling C of the stadium facing the ground, and can project an image on the sand pit SD of the stadium.

  As shown in FIG. 5, the recording line RL2 is a line substantially parallel to the crossing line TO. The image data of the recording line RL2 is image data created based on the jump record of the long jump world record holder.

Yes. The recording line image storage unit 130 outputs the image data of the recording line RL2 to the image data output unit 135. The recording line RL2 is a single “straight line” image of a specific color (for example, yellow). In the present embodiment, the portion other than the projected “straight line” is an image representing a black plain image.

  The image data output unit 135 inputs the image data of the recording line RL <b> 2 from the recording line image storage unit 130 based on an instruction from the first control unit 120. Then, the image data is output to the projector 200 via the cable CB.

  With such a configuration, when the first control unit 120 of the image supply apparatus 100C receives an operation signal of the image output key from the operation input unit 121a, the first control unit 120 issues an instruction to the image data output unit 135 and the image data of the recording line RL2. Is output to the projector 200.

  In the image projection system 3 described above, the image supply device 100C starts outputting the image data of the world recording line RL2 to the projector 200 when the image output key provided in the operation input unit 121a is pressed by the user. The projector 200 can project a static recording line RL2 of world recording based on the input image data onto the sandbox SD.

Project. Thereby, by observing the recording line RL2 projected on the sandbox SD, the spectator who is watching the competition in the stadium can recognize the world record. That is, it is beneficial for the spectator to watch and enjoy the game while comparing the competition state of the player H5 with the recording line RL2. Furthermore, the spectator can recognize whether or not the world record has been updated by comparing the competitor and the record line RL2 without waiting for the measurement result to be obtained after the competition is over. Be beneficial.

  (2) The world record that the image projection system 3 projects onto the sandbox SD is represented as a recording line RL2, that is, a “straight line”. As a result, the spectator can watch the competition while comparing the competition state of the athlete H5 with the record line RL2, and thus it is possible to easily see whether or not the athlete H5 exceeds the world record. It is beneficial.

  (3) When the image projection system 3 projects the recording line RL2 onto the sandbox SD, the player H5 can compare the world record with his / her competition state. For this reason, since the player H5 can play the game while visually recognizing the recording line RL2, it is beneficial. Also, when practicing a competition, it is useful to project such a recording line RL2 onto the sandbox SD so that the target of the practice can be visually recognized.
