PROBLEM TO BE SOLVED: To provide an image projection system, an operation device and an image projection device specification method, capable of specifying a projector to execute an operation for projection to cause the projector to execute operation processing without delay, even when identification information on the projector on a network cannot be grasped.SOLUTION: A terminal device 100 includes: a retrieval unit 106 for retrieving a projector on a network 10; a projection image acquisition unit 101 for acquiring image information on an image to be projected by a projector retrieved by the retrieval unit 106; a projected surface projection image acquisition unit 102 for acquiring image information on an image projected on a screen; a determination unit 103 for determining whether or not the image information acquired by the projection image acquisition unit 101 is matched with the image information acquired by the projected surface projection image acquisition unit 102; and an operation instruction unit 104 for performing an operation instruction to the projector in which the determination unit 103 determines that the image information is matched with each other. |
