Abstract:
1. A three-dimensional image display device comprising: a two-dimensional image display screen having color filters in which each color is disposed on sub-pixels obtained by dividing one pixel in a vertical direction and same color is disposed on each column of sub-pixels; an optical plate having an exit pupil, the exit pupil being provided for making a viewing zone different for each pixel and having a longitudinal axis disposed to be inclined from a vertical direction of the two-dimensional image display screen at a non-zero angle between −45° and 45°, the viewing zone being a region in which parallax information displayed on the two-dimensional image display screen is observed, the parallax information being presented in a horizontal direction of the two-dimensional image display screen; a viewing position displacement detecting unit that detects a viewing position displacement amount in the vertical direction of the two-dimensional image display screen, the viewing position displacement amount being a displacement amount between a viewing position on which a three-dimensional image displayed on the three-dimensional image display device is to be observed and an actual position of an observer; a viewing zone shift amount determining unit that determines a shift amount of the parallax information in the vertical direction based on the viewing position displacement amount; and a viewing zone adjusting unit that shifts the parallax information disposed on each pixel of the two-dimensional image display screen in the vertical direction by the shift amount.
