Three-dimensional digital image data comes from a stereographic imaging arrangement () that takes a first raw image () along a first optical axis and a second raw image () along a second optical axis. The imaging arrangement () has a maximum imaging depth () and a minimum imaging depth (). It transmits the first raw image () and the second raw image () to a receiving device () along with an indication of a disparity range between a maximum disparity value and a minimum disparity value. The maximum disparity value is a measure of a difference between locations in the first () and second () raw images that represent the minimum imaging depth (). The minimum disparity value is a measure of a difference between locations in the first () and second () raw images that represent the maximum imaging depth ().

Method and devices for generating, transferring and processing three-dimensional image data

For reducing the effect of reverse half-occlusion in a 3D presentation on a screen, a virtual window is created in front of the screen. The screen is to be used for combining a left image and a right image for the 3D presentation. The virtual window is created by removing image data at a left edge of the left image and at a right edge of the right image before combining the left image and the right image on the screen.

Supporting a 3D presentation

An image processing is applied in common to image data for a first image and to image data for a second image. The image data for the first image and the image data for the second image are moreover compared as a basis for matching a visual appearance of images for a stereoscopic presentation. The visual appearance can be matched in the current pair of images by adjusting at least one of the images accordingly and/or in future pairs of images by adjusting parameters of at least one of the image capturing components providing the image data.
