Embodiment Construction

[0023] In the following, several embodiments of the invention will be described in the context of stereoscopic viewing with 3D glasses. It should be noted, however, that the present invention is not limited to any particular display technology. In fact, the different embodiments find application in any environment where stereoscopic viewing is required, such as movies and television. Also, although the instructions use certain camera settings as examples, different camera settings may be used.

[0024] Figure 1a , 1b , 1c and 1d show the setup for forming a stereoscopic image for the user. exist Figure 1a , shows a situation where a person views two spheres A1 and A2 with both eyes E1 and E2. Sphere A1 is closer to the viewer than sphere A2, the corresponding distance to first eye E1 is L E1,A1 and L E1,A2 . The different objects reside in spaces of respective (x, y, z) coordinates defined by the coordinate systems SZ, SY and SZ. The distance between human eyes d 12 ...

Abstract

The invention relates to a camera device. The camera device has a view direction and comprises a plurality of cameras, at least one central camera and at least two peripheral cameras. Each said camera has a respective field of view, and each said field of view covers the view direction of the camera device. The cameras are positioned with respect to each other such that the central cameras and peripheral cameras form at least two stereo camera pairs with a natural disparity and a stereo field of view, each said stereo field of view covering the view direction of the camera device. The camera device has a central field of view, the central field of view comprising a combined stereo field of view of the stereo camera pairs, and a peripheral field of view comprising fields of view of the cameras at least partly outside the central field of view.

Description

Background technique [0001] Digital stereoscopic viewing of still and moving images has become common, and equipment for viewing 3D (three-dimensional) movies is more widely available. Theaters offer 3D movies based on viewing movies with special glasses that ensure that for each frame of the movie the left and right eyes see different images. With 3D-capable gamers and televisions, the same approach has been brought to the home. In practice, a movie consists of two views (one for the left eye and one for the right eye) of the same scene. These views are created by filming with special stereo cameras that directly create the content suitable for stereo viewing. The human visual system creates a 3D view of a scene as the view is presented to the two eyes. The disadvantage of this technology is that the viewing area (movie screen or TV) only occupies a part of the field of view, so the experience of 3D viewing is limited. [0002] For a more realistic experience, devices hav...
