[0032] then refer to Figure 7 , the three-dimensional image display device 700 according to the first embodiment is described. Figure 7 is a block diagram showing the three-dimensional image display device 700 .

[0033] The three-dimensional image display device 700 of the first embodiment includes an optimum element image generation unit 701 and a display unit 702 . The optimal elemental image generation unit 701 generates an optimal elemental image. The display unit 702 includes a two-dimensional display device 101 and a light control element 102 .

[0034] The optimum element image generation unit 701 receives the initial element image 751 and generates an optimum element image 752 based on the initial element image 751 . The initial element image 751 is an element image generated by a method disclosed in, for example, JP-A 2004-212666 (KOKAI). Alternatively, the optimum element image generation unit 701 may generate the optimum element image 752 based on, for exampl...

[0045] now refer to Figure 10 , the three-dimensional image display device 1000 according to the second embodiment is described. Figure 10 is a block diagram showing the three-dimensional image display device 1000 of the second embodiment. The second embodiment differs from the first embodiment in the optimum elemental image generation unit.

[0046] The optimal element image generation unit 1001 incorporated in the second embodiment receives not only the initial element image 751 but also the target image 1052, and generates the optimal element image 752 based on these images. The target image 1052 is an image displayed on the display unit that is expected to be viewed when an observer views the three-dimensional image display apparatus 1000 through one eye from at least one viewpoint.

[0047] refer to Figure 10 and Figure 11 , an operation example of the three-dimensional image display device 1000 of the second embodiment is described. Figure 11 is a flowchart use...

[0105] then refer to Figure 14 , the three-dimensional image display device 1400 according to the third embodiment is described. The three-dimensional image display device 1400 of the third embodiment is obtained by adding a parallax image generation unit 1401 to the three-dimensional image display device 1000 of the second embodiment.

[0106] The parallax image generation unit 1401 receives the model data 1451 , and generates parallax images viewed from one or more preset viewpoints, and outputs the parallax images as the target image 1502 . Model data 1451 represents the three-dimensional coordinates and brightness values ​​of objects displayed on the three-dimensional image display device 1400 . The parallax image generating unit 1401 receives the model data 1451, and generates a parallax image by performing, for example, computer graphics (CG) rendering.

[0107] refer to Figure 14 and Figure 15 , to describe a part of the operation of the three-dimensional image d...

Abstract

According to one embodiment, a three-dimensional image display apparatus includes a display unit and a generating unit. The display unit includes a two-dimensional image display device includes a display surface with a plurality of pixels arranged in a matrix, and a plurality of light ray control elements provided on the display surface of the two-dimensional image display device corresponding to the pixels. The generating unit generates an optimal elemental image by determining a value of at least one pixel from a weighted sum of values of at least two pixels of a generated image or an input image, and weights calculated based on light ray distributions indicating directions and scattering degrees of light rays from the light ray control elements. The display unit displays the optimal elemental image.

Description

technical field [0001] Embodiments described herein generally relate to three-dimensional image display devices and methods. Background technique [0002] Devices for displaying three-dimensional images that can be observed with the naked eye have recently been developed. One such device utilizes an integral imaging (II) scheme that allows an image to be viewed such that its aspect changes according to changes in the viewer's point of view. In the II display device, a plurality of light control elements such as lenses and baffles for controlling the direction and distribution of light are provided in front of a conventional two-dimensional image display to produce different images for the right and left eyes and thus produce Three-dimensional effect. [0003] However, the II scheme has the disadvantage that multiple images and blurring may occur when the image is viewed from a certain viewpoint. The effect will be called "Multiple Blur".
