Abstract
A picture presentation system 1 presents a user U with a picture where a virtual image Di is created in a space in front of the user U. The picture presentation system 1 includes a hologram mirror 10 configured to reflect a picture composed of light of a specific wavelength at an angle different from an angle of incidence and transmit light other than the light of the specific wavelength, and a screen 20 configured to display the picture toward the hologram mirror. The hologram mirror 10, being placed opposite to the user U, reflects the picture from the screen 20 in such a way that the user U can visually recognize the virtual image Di of the picture at a position on the opposite side from the user U across the hologram mirror 10 (arrow AR1).
