Image display device

Abstract

An image display device includes: an input unit that inputs image data constituted with pixel data, each set of the pixel data being generated based upon a plurality of image signals output from a plurality of image-capturing pixels arrayed in correspondence to a plurality of photographic micro-lenses distinct from one another; a generation unit that generates display image data containing three-dimensional information based upon the image data; a display unit constituted with a plurality of display pixels disposed in a two-dimensional pattern, which emits light fluxes from the plurality of display pixels in correspondence to the display image data; and a micro-lens array that includes a plurality of micro-lenses, via which a three-dimensional image is formed by combining the light fluxes emitted from the plurality of display pixels, disposed in a two-dimensional array pattern.

What is claimed is: 
     
         1 . An image display device comprising:
 an input unit into which a plurality of image signals are inputted, the image signals being outputted from a plurality of image capturing pixels that are disposed in correspondence to a plurality of image capturing micro-lenses, each of the image capturing pixels receiving light that has passed through a corresponding one of the image capturing micro-lenses;   a plurality of display micro-lenses;   a plurality of display pixels that emit light for forming a three-dimensional image to each of the display micro-lenses, the plurality of display pixels being disposed in correspondence to the plurality of display micro-lenses; and   a generator that generates display image data that includes three-dimensional information, based upon the plurality of image signals inputted into the input unit, wherein:   the three-dimensional image includes (i) a first light spot at which light from a first display pixel disposed corresponding to a first display micro-lens among the plurality of display micro-lenses and light from a second display pixel disposed corresponding to a second display micro-lens among the plurality of display micro-lenses intersect and (ii) a second light spot at which light from a third display pixel disposed corresponding to the first display micro-lens and light from a fourth display pixel disposed corresponding to the second display micro-lens intersect, and a shortest distance between the first light spot and the display micro-lenses is different from a shortest distance between the second light spot and the display micro-lenses, and   the generator allocates the image signals from the image capturing pixels to the display pixels disposed at positions achieving symmetry along a given direction, in reference to a pseudo-optical axis of the display micro-lenses such that the display image data is inverted with respect to synthetic image data generated from the image signals.   
     
     
         2 . The image display device according to  claim 1 , further comprising:
 a lens that generates a virtual image of the image formed by the display image data.   
     
     
         3 . The image display device according to  claim 2 , wherein:
 the lens is arranged at a position at which the image formed by the display image data can be observed as a virtual image by a user through the lens.
