Abstract:
When a material sharing mode using a projector at a first point and the projector at a second point is active, the projector at the first point causes a projection unit to project a video image from a first personal computer onto a projection screen, causes an image taking unit to take an image of the projected video image on the projection screen, causes a control unit of the projector or the first personal computer to compare the taken video image with a supply video image supplied from the first personal computer to the projector, and supplies a difference video image generated based on the comparison to the projector at the second point so as to be superimposed on the supply video image.
