Three-dimensional image display device, three-dimensional image display method and three-dimensional display image data generating method

摘要

A three-dimensional image display device includes a display portion having pixels arranged in the form of a matrix in a planar display surface to have fixed horizontal and vertical pitches, a light ray control portion having first optical apertures arranged in front of the display portion to have a first pitch in a horizontal direction which limit light rays in the horizontal direction and second optical apertures to have a second pitch in a vertical direction which converge the light rays at a certain view distance, and a display drive portion which gives element images generated based on parallel projected images to pixel groups along the horizontal direction and gives image segments obtained by interleaving perspective projected images in the vertical direction. Preferably, the first pitch is equal to an integer multiple of the horizontal pitch of the pixels, and the second pitch is smaller than the vertical pitch.
