ABSTRACT:
There is reproduced a three-dimensional image in which there is no dimness or no cross talk and which is light and high in resolution, by a three-dimensional information reproducing apparatus comprising a liquid crystal panel for displaying a discrete Fourier transform image, a light source array which is disposed to the rear of the liquid crystal panel and which emits parallel light, and a synchronous control device for switching, with time division, the discrete Fourier transform image that is displayed in the liquid crystal panel and also an angle of the parallel light that is emitted from the source light array. No color dislocation occurs in a reproduced image, resolution is enhanced, and a light three-dimensional image is reproduced, by a three-dimensional information reproducing apparatus comprising a liquid crystal panel for displaying with time division a discrete Fourier transform image resolved into color components, an illumination device for changing a color of emitted light with time division, and a synchronous control device for synchronizing and switching the image that is displayed on the liquid crystal panel, and the color of the illumination device.
