摘要：
An image projection system includes a projector to project a projected image onto a drawing surface of a whiteboard, a drawn-image detecting portion to detect a drawn image which is drawn on the drawing surface of the whiteboard while the projector is projecting the projected image, and a modification portion which, in the case where the drawn image is detected, to specify from the projected image which is projected onto the projection surface a part including at least a drawn image part overlapping the detected drawn image, and modify the specified part of the projected image, on the basis of the detected drawn image, so as to emphasize or cancel the drawn image.
