ABSTRACT:
To provide a projection-type image display system, a projector, a program, an information storage medium, and an image projection method that enable simple changing of a projection position, a liquid-crystal projector is provided with: a sensor which senses a projection target area and outputs sensing information; an edge detection section which outputs detection information, based on the sensing information; a projectable area determination section which determines a projectable area which has no obstructions within the projection target area, based on the detection information; a projection area selection section which selects a projection area within the projectable area, based on a user selection or a predetermined reference; a projection-area/pixel-area associating section and a lens adjustment section which performs predetermined adjustments in such a manner that an image is displayed on the projection area, and an image projection section which projects an image towards the projection area, based on the input image information.
