no. 1 Embodiment approach ）

[0064] Such as figure 1 As shown, a three-dimensional image audio-visual system 1000 includes a parallax image generation device 100 and active shutter glasses 200 .

[0065] The parallax image generating device 100 is, for example, a plasma display, a liquid crystal display, an organic EL display, or the like. In addition, the parallax image generating device 100 is not limited to the above-mentioned display, and may be a digital video camera, a digital still camera, or the like. In addition, the parallax image generation device 100 may be a device built in a display, a camera, or the like.

[0066] The parallax image generation device 100 includes a display surface 101 for displaying images. Assume that the display surface 101 is parallel to the XY plane. As an example, the display surface 101 can display an image composed of a plurality of pixels arranged in m (natural number) rows and n (natural number) columns.

[0067] Here, it is assumed that m and n are 1080 and 19...

no. 2 Embodiment approach ）

[0203] That is, by recording a program for realizing the parallax image generation method on a recording medium such as a floppy disk, the processing shown in the above-mentioned embodiments can be easily implemented in an independent computer system.

[0204] Figure 21A ~ Figure 21C It is an explanatory diagram in a case where a computer system implements the parallax image generation method of the above-mentioned embodiment using a program recorded on a recording medium such as a flexible disk.

[0205] Figure 21A An example of the physical format of a floppy disk as the main body of the recording medium is shown. Figure 21BIndicates the appearance, cross-sectional structure, and floppy disk viewed from the front of the floppy disk. The floppy disk FD is housed in the case F. On the surface of the disk, a plurality of tracks Tr are formed concentrically from the outer periphery toward the inner periphery, and each track is divided into 16 sectors Se in the angular direc...

Abstract

A parallax image generation device is provided with: a depth value correction unit (110) that performs a correction process for correcting depth values in such a manner that, among a plurality of depth values constituting a depth image, the closer a depth value is to the edge of the depth image, the closer a position corresponding to the depth value is to a display surface for displaying a parallax image; and a parallax image generation unit (120) that uses a 2D image and the depth image corrected by the correction process to generate first and second parallax images having mutual parallax.

Description

technical field [0001] The present invention relates to a parallax image generation device, a parallax image generation method, a program, and an integrated circuit for generating a parallax image for expressing a three-dimensional image. Background technique [0002] In recent years, various techniques for expressing a three-dimensional image using a plurality of images with parallax have been developed. In the case of expressing a 3D image using a plurality of images with parallax, there is a problem that an object at an end of the 3D image suddenly loses its three-dimensional effect near the end, and the 3D image looks very unnatural. [0003] Patent Document 1 discloses a technique for eliminating the unnatural appearance at the edge of a three-dimensional image (hereinafter, referred to as conventional technique A). [0004] prior art literature [0005] patent documents [0006] Patent Document 1: JP-A-2010-268097 Contents of the invention [0007] The problem to...
