ABSTRACT:
Video image data is converted into spatial frequency information using Fourier transformation. The spatial frequency information is provided to an information display unit. The spatial frequency information as a phase distribution is displayed on the information display unit, light is irradiated onto the information display unit using a light source, and the amount of light that is irradiated by the light source is adjusted based on the video image data. And diffraction light, which is irradiated by the light source and modulated as the spatial frequency information by the information display unit, is projected onto a projecting unit.
