PROBLEM TO BE SOLVED: To photograph only the information added to a projected image on a screen by an individual camera, and to clearly store the photographed image, while making the photographed image correlate with the projected image. SOLUTION: A projector 11 is connected to a digital camera 13 by a wireless LAN etc. When the shutter key of the digital camera 13 is depressed, the digital camera 13 is controlled under the control of a PC 12 so that the projected image displayed on the screen 16 by the projector 11 can be made in a non-displayed state, and the additional information remaining on the screen 16 at that time can be photographed. Then, the projected image displayed on the screen 16, immediately prior to photographing is obtained, and the projected image and the photographed image, with additional information photographed by the digital camera 13, are correlated with each other and recorded to a memory for the PC 12 or a memory card 11a.
