ABSTRACT:
According to the present invention, a plurality of video image data are converted into individual spatial frequency information using Fourier transformation. The individual spatial frequency information is provided to a plurality of information display unit corresponding to the individual spatial frequency information. The spatial frequency information corresponding to the plurality of video image data is displayed on the plurality of information display unit, light is irradiated onto the plurality of information display unit using a plurality of light sources corresponding to the plurality of information display unit. The spatial frequency information that is displayed by the plurality of information display unit is projected by using diffraction light, and a plurality of video images are synthesized on projection surfaces.
