Abstract: The invention relates to creating and viewing stereo images, for example stereo video images, also called 3D video. At least three camera sources with overlapping fields of view are used to capture a scene so that an area of the scene is covered by at least three cameras. At the viewer, a camera pair is chosen from the multiple cameras to create a stereo camera pair that best matches the location of the eyes of the user if they were located at the place of the camera sources. That is, a camera pair is chosen so that the disparity created by the camera sources resembles the disparity that the user's eyes would have at that location. If the user tilts his head, or the view orientation is otherwise altered, a new pair can be formed, for example by switching the other camera. The viewer device then forms the images of the video frames for the left and right eyes by picking the best sources for each area of each image for realistic stereo disparity.

Abstract: There are disclosed various methods, apparatuses and computer programs for processing video information. In an embodiment of the method a first video stream representing a left view of a part of a scene and a second video stream representing a right view of the part of the scene are received. Optical enhancement data regarding image pairs of the first video stream and the second video stream and transform data for warping at least one of the left view and the right view are obtained (514). The first video stream and the second video stream are warped (516-522) on the basis of the optical enhancement data and the transform data.

Abstract: A method, apparatus and computer program product are provided to combine images captured by multiple cameras into a composite panoramic image, such as a 360° panorama, in a manner that reduces image defects and other artifacts at or near a seam between images. In some implementations of example embodiments, the overlapping portions of two images are divided into a plurality of seam regions. Upon selection of a seam region, the seam region is further divided into seam segments. In each seam segment, a depth level associated with the segment is used to calculate convergence value that is applied such that different scaling factors may be applied to image elements at different depths within a given image. Based on the applied convergence values and the resulting stitching at the seam region the image quality at the seam area can be efficiently improved.

First information of a first graphic object for rendering a second graphic object and second information of the second graphic object for rendering the second graphic object are formed or received. Dependency information between the first and second graphic objects is formed or received, where the dependency information comprises information for rendering the second graphic object depending on overlapping of said first graphic object and the second graphic object in a viewing direction. The second graphic object is rendered by creating second pixel data using the second information of the second graphic object and the first information of the first graphic object, where the rendering of the second graphic object is carried out for such part of the second graphic object that is overlapped by the first graphic object in the viewing direction.
