A high resolution photographed image, picked up by a camera device, is projected by using a projector. In a case where there is a magnifying operation of a display image that is projected, image data of the display image that is reduced in accordance with the resolution at the projector side, is not magnified, but the image data of a display region corresponding to the size of a requested magnification ratio in the original photographed image, is reduced, to project a magnified image that is a display image based on the image data. |
