Embodiment approach 1

[0063] figure 1 The configuration of the stereoscopic image processing device 100 according to this embodiment is shown. The stereoscopic image processing device 100 includes: a stereoscopic effect adjustment unit 110 that adjusts the stereoscopic effect based on a user's response to an image corresponding to a stereoscopic display; and a parallax information storage unit 120 that stores an appropriate parallax specified by the stereoscopic effect adjustment unit 110; Configure a virtual camera, generate a common viewing volume based on the virtual camera and appropriate parallax, and project the viewing volume generated by performing deformation processing on the common viewing volume on the projection surface, thereby generating multiple two-dimensional images, that is, parallax The parallax image generating part 130 of the image; the information obtaining part 104 having the function of obtaining the hardware information of the display device itself and the stereoscopic dis...

Embodiment approach 2

[0117] Embodiment 2 differs from Embodiment 1 in that the stereoscopic image processing device 100 generates a common viewing volume by enlarging the angle of view of the virtual camera. Such processing can be done with figure 1 The stereoscopic image processing device 100 shown has the same configuration, but the view volume generation unit 136 also has the function of expanding the angle of view of the virtual camera and generating a common view volume. Even the two-dimensional image generation unit 140 also has the function of expanding the number of pixels in the horizontal direction according to the expansion of the virtual camera viewing angle to obtain a two-dimensional image, and cutting out a horizontal area corresponding to the final use area from the two-dimensional image. A function of a two-dimensional image with L number of pixels. A specific expansion amount of the number of pixels in the horizontal direction will be described later.

Embodiment approach 3

[0130] In Embodiment 1 and Embodiment 2, the positions of the front cross section and the rear cross section are determined by the Z buffer method. In the present embodiment, the front projection plane and the rear projection plane are set as the front cross section and the rear cross section. This processing can be realized with the same configuration as the stereoscopic image processing device 100 according to the second embodiment, but instead of applying the front facet of the object and the rear facet of the object to generate the common viewing volume, the view volume generation unit 136 has the function of applying the front projection plane and the rear projection plane. The function of surface generation common view volume. Here, the positions of the front projection plane and the rear projection plane are determined by the user or the like so as to sufficiently include the object to be stereoscopically displayed. By using such a front projection plane and a rear pro...

Abstract

The presnent invention provided a 3D image processing apparatus and method. A 3D image processing apparatus first generates a combined view volume that contains view volumes set respectively by a plurality of real cameras, based on a single temporary camera placed in a virtual 3D space. Then, this apparatus performs skewing transformation on the combined view volume so as to acquire view volumes for each of the plurality of real cameras. Finally, two view volumes acquired for the each of the plurality of real cameras are projected on a projection plane so as to produce 2D images having parallax. Using the temporary camera alone, the 2D images serving as base points for a parallax image can be produced by acquiring the view volumes for the each of the plurality of real cameras. As a result, a processing for actually placing the real cameras can be skipped, so that a high-speed processing as a whole can be realized.

Description

technical field [0001] The invention relates to a stereoscopic image processing technology, in particular to a method and a device for generating a stereoscopic image based on parallax images. Background technique [0002] In recent years, inadequacy of network infrastructure has been regarded as a problem, but rather than ushering in the transition to broadband, people are starting to pay attention to the fact that there are few types or quantities of content that can effectively use broadband. No matter in any era, images are the most important means of expression, and the previous combination mostly involves the improvement of display quality or data compression rate. Compared with it, the technical combination of expanding the possibility of expression itself feels retrogressive. [0003] Among them, stereoscopic image display (hereinafter simply referred to as stereoscopic display) has been studied in various ways, and has been put into practical use in a somewhat limit...
