PROBLEM TO BE SOLVED: To allow an access to display data to be displayed from an image display apparatus, only at a time programmed.SOLUTION: An image display system 1 includes an information processing apparatus (information processing terminal 20 and a schedule management apparatus 30), and a projector 10 connected to each other, to display a projection file input from the information processing apparatus on a projector 10. The information processing apparatus includes transmission means 22, 33 for transmitting the projection file and programmed time information indicating a time to use the projection file, to the projector 10. The projector 10 includes: storage means 12 for storing the projection file and the programmed time information to be transmitted from the information processing apparatus; time management means 14 for acquiring the current time; and authentication means 15 which determines whether the current time is coincident with the programmed time information or not, when there is an access to the projection file, to allow the access to the projection file when they are coincident with each other.SELECTED DRAWING: Figure 3 |
