PROBLEM TO BE SOLVED: To perform effective rendition with interest for a comparatively large screen in a projector system. SOLUTION: A projector system PS comprises: a projection part 110 for receiving a video signal Dp and reflecting a projection image GP on the screen SC; a position moving part 120 for moving the position of the projection image GP; a frame buffer 135 for holding a virtual frame data VF with an image domain of size corresponding to the screen SC; an image extraction part 130 for extracting the video signal Dp from the virtual frame data VF to output the signal to the projection part; and a control part 140 for controlling the position moving part 120 and image extraction part 130 so that the position of the projection image GP corresponds to the video signal Dp.
