Problems solved by technology

[0024] In addition, in the multi-eye system, when it is strictly necessary to display a two-dimensional image viewed from a position deviated from the viewing distance, it cannot be realized in the perspective projection image obtained by a single camera, and it is necessary to add images from different cameras
In this case, there is also a problem that the image becomes discontinuous at the switching position of the parallax number

Embodiment 1

[0119] In this embodiment, only the effective horizontal disparity in the stereoscopic view is provided. A QUXGA-LCD (number of pixels 3200×2400, screen size 422.4mm×316.8mm) was used for the liquid crystal display element. The smallest driving unit is each sub-image unit of R, G, and B. Usually, three sub-image units of R, G, and B arranged horizontally form a pixel (a group of three), but in the display unit of this embodiment In order to increase the horizontal resolution, parallax images are configured on each sub-image unit of R, G, and B. The sub-picture unit has a lateral width of 44 μm and a vertical length of 132 μm. A backlight is placed on the back of the display unit, and cylindrical lenses with a width of 0.704mm are arranged on the observer side, and a lenticular lens sheet for providing parallax information in the II method only in the horizontal direction is combined. For the parameters of the lens, since the pixel surface of the liquid crystal display elemen...

Embodiment 2

[0126] In addition to Embodiment 1, when the observation point is moved arbitrarily within the field of view by moving the mouse, it is possible to rotate the display of the object in the two-dimensional image in conjunction with the mouse. More specifically, the moving direction of the mouse and the moving direction of the observation point are set to opposite directions with respect to the horizontal vector on the screen. Furthermore, by using the parallax image for expansion among the element images selected in this embodiment as it is, the three-dimensional image observed from the observer's preferred direction can be used as the viewable area in the field of view at the resolution of three-dimensional image display. Two-dimensional image of arbitrary position recognition to print out.

Embodiment 3

[0128] In addition to Embodiment 1, when the parallax image numbers are arranged by the formula (2), the signal voltage difference at the boundary of switching the parallax image numbers is detected, and the degree of defocus is changed according to the magnitude ( FIG. 21 ). , to focus on the screen in the content with a large amount of protrusion / recess. In addition, in a display similar to natural defocus, the content with a small amount of protrusion / recess can be clearly displayed as a whole. The signal voltage difference reflects the degree of discontinuity of the seam of the parallax image, and the defocus amount tends to be set small for content with a small protrusion / recess amount, and to be set larger for content with a large protrusion / recess amount .

Abstract

The present invention makes it possible to rapidly obtain a two-dimensional image which is not discontinuous and does not include distortion from three-dimensional image display data. When a two-dimensional image is displayed, a viewing point within a viewing zone is assumed, and a parallax image displayed on pixels positioned at a position where a line connecting the viewing point and an exit pupil, and the display unit cross each other or positioned in the vicinity thereof in a state that a three-dimensional image is displayed is developed and displayed within a corresponding elemental image including the pixels.

Description

technical field [0001] The present invention relates to a three-dimensional image display device. Background technique [0002] Although three-dimensional image display technologies can be classified into various categories, they are generally classified into a binocular parallax method that uses binocular parallax and an aerial image reproduction method that actually forms an aerial image. [0003] The binocular parallax method includes a binocular type and a multi-eye type. The binocular type allows the left and right eyes to see images for the left eye and images for the right eye (parallax images) obtained by perspective projection from two shooting positions corresponding to the left and right eyes. Way. In addition, the multi-eye system is a system that further increases the number of image capturing positions compared to the two-eye system. [0004] As aerial image reproduction methods, there are holography and integration and imaging methods (hereinafter referred ...
