PROBLEM TO BE SOLVED: To improve usability of an interactive function.SOLUTION: In an image display system 1, a projector device PJ receives image data for display and image data for inspection from an information processing device JS through a communication line L, and displays an image on a projection surface TM on the basis of the image data for display. When an electronic pen Pn instructs and operates on the projection surface TM, a coordinate position acquisition transmission section ZP acquires a coordinate of a position instructed and operated, and outputs coordinate position information to the projector device PJ and the information processing device JS. The information processing device JS performs image processing of mouse pointer or the like for a coordinate position and outputs to the projector device PJ, and the projector device PJ measures a lapsed time from reception of the coordinate position information to detection of the image processing and performs execution control of the image processing in the information processing device JS according to the lapsed time. |
