Embodiment approach 1

[0071] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0072] figure 1 It is a configuration diagram of the multi-viewpoint image generation device according to the first embodiment. figure 1 Among them, the multi-viewpoint image generation device is composed of an image acquisition unit 101, a parallax calculation unit 102, a display characteristic storage unit 103, a parallax analysis unit 104, a viewpoint generation unit 105, a viewpoint synthesis unit 106, and a naked-eye stereoscopic display unit 107.

[0073] The image acquisition unit 101 receives a left-right (LR) two-parallax image such as Blu-ray 3D or side-by-side format (side-by-side), top-and-bottom format (top-and-bottom), and decomposes it into a left-eye image (L image) and right-eye image. The eye image (R image) is used, and the image is output to the parallax calculation unit 102 and the viewpoint generation unit 105 .

[0074] The parallax calculation ...

Embodiment approach 2

[0144] The difference between the multi-viewpoint image generation device of Embodiment 2 and the multi-viewpoint image generation device of Embodiment 1 is that a depth image representing the depth of each pixel of a two-viewpoint image is obtained, and a multi-viewpoint image is generated using the obtained depth image.

[0145] Figure 13 It is a configuration diagram of a positioning processing device according to Embodiment 2 of the present invention. Figure 13 in, right with figure 1 The same symbols are used for the same constituent elements, and explanations thereof are omitted. Figure 13 Among them, 1301 is a depth image acquisition unit which acquires a depth image input from the outside and sends it to a parallax analysis unit 1302 . For example, since 3D model data is included in content produced by CG, etc., it is easy to output accurate 3D depth information, and a depth image can be easily created on the content side. In addition, as another example, a dista...

Abstract

An image acquirer acquires paired left and right viewpoint images. A disparity calculator calculates a disparity between the left and right viewpoint images. A display properties memory stores naked-eye stereoscopic display properties such as recommended disparity values and a cross-talk rate. A disparity analyser reads the naked-eye stereoscopic display properties from the display properties memory and uses these properties to perform a disparity adjustment on the left and right viewpoint images. A multi-viewpoint image generator uses the disparity as adjusted by the disparity analyser to generate a multi-viewpoint image by performing a shift on each pixel of the left and right viewpoint images.

Description

technical field [0001] The invention relates to a technique for generating multi-viewpoint images for a naked-eye stereoscopic display from images of left and right two viewpoints. Background technique [0002] Among stereoscopic displays, there are glasses-type stereoscopic displays that use 3D glasses to switch between light transmission and light blocking, and naked-eye stereoscopic displays that use parallax barriers such as parallax barriers or lenticular lenses. The content displayed on the glasses-type stereoscopic display is composed of left and right two-viewpoint images, while the content displayed on the naked-eye stereoscopic display is composed of multi-viewpoint images in order to prevent reverse viewing corresponding to the viewing position. [0003] Here, the current mainstream stereoscopic display is a glasses-type stereoscopic display, so most of the currently distributed 3D content consists of images from left and right viewpoints. Therefore, 3D contents ...
