Abstract:
1. An apparatus that presents a projection image, the apparatus comprising: a screen; plural projectors, each of which projects a section of the projection image onto the screen to reproduce the projection image; a projected-section-determining unit that determines as a projected section the section of the projection image based on an input image signal, said section of the projection image corresponding to a part of the screen onto which each of the projectors projects the section of the projection image; an image-signal-generating unit that generates an image signal corresponding to the section of the projection image which each of the projector projects onto the part of the screen, based on the input image signal and the projected section which has been determined by the projected-section-determining unit; and a projectors-controlling unit that controls the projectors, respectively, to adjust any one of centers and ranges of the projections by the projectors based on the projected section which has been determined by the projected-section-determining unit, and to adjust a number of projectors assigned to project at least one section of the projection image, based on an amount of information per unit area of the projection image.
