Image display device

Abstract

An image display device includes: an input unit into which image signals are inputted, the image signals being outputted from image capturing pixels disposed in correspondence to 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; display micro-lenses; display pixels that emit light for forming a three-dimensional image to each of the display micro-lenses, the display pixels being disposed in correspondence to the display micro-lenses; and a generator that generates display image data that includes three-dimensional information, based upon the image signals inputted into the input unit. The generator allocates the image signals outputted from the image capturing pixels to the display pixels arranged at symmetrical positions in a predetermined direction, using a pseudo-optical axis of each of the display micro-lenses as a reference.

What is claimed is: 
     
         1 . An image display device, comprising:
 a display that displays an image by outputting light from the display to a plurality of micro-lenses; and   a display controller that controls displaying the image, by the display, by (1) outputting first light from the display through a first micro-lens among the plurality of micro-lenses, (2) outputting second light from the display through a second micro-lens among the plurality of micro-lenses, (3) outputting third light from the display through the first micro-lens and (4) outputting fourth light from the display through the second micro-lens, thereby forming a three-dimensional image having spatial depth, wherein;   the first light at a first position and the second light at a second position form the three-dimensional image, with a distance between the first position and the display being different from a distance between the second position and the display,   the first light and the fourth light intersect at the first position and the second light and the third light intersect at the second position, and   the first and second micro-lenses are adjacent to each other.   
     
     
         2 . An image display device according to  claim 1 , wherein
 the display controller controls displaying by the display, by outputting the first light from a first pixel of the display through the first micro-lens and by outputting the second light from a second pixel of the display through the second micro-lens.   
     
     
         3 . An image display device according to  claim 2 , wherein
 the display controller does not change a position of the first pixel even if a distance between the display and the first position varies, and does not change a position of the second pixel even if the distance between the display and the second position varies.
