Abstract: Three-dimensional digital image data comes from a stereographic imaging arrangement (501, 502, 1201) that takes a first raw image (601) along a first optical axis and a second raw image (602) along a second optical axis. The imaging arrangement (501, 502, 1201) has a maximum imaging depth (506) and a minimum imaging depth (505). It transmits the first raw image (601) and the second raw image (602) to a receiving device (1102) 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 (601) and second (602) raw images that represent the minimum imaging depth (505). The minimum disparity value is a measure of a difference between locations in the first (601) and second (602) raw images that represent the maximum imaging depth (506).

Abstract: 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.

Abstract: A method (100), apparatus (200) and computer program (204) for receiving an indication of a disparity range (SIVP1 D, SIVP2D) of an object scene from each of two or more stereoscopic imaging viewpoint pairs (SIVPi, SIVP2); receiving an indication of a disparity constraint (SDD) of a stereoscopic display (903); and selecting a stereoscopic imaging viewpoint pair whose disparity range is the largest and whose disparity range satisfies the disparity constraint of the stereoscopic display

Abstract: 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.

Abstract: The present invention provides a technique for receiving one or more view signals, each containing information about multiple input images; and forming a combined stereoscopic image signal based at least partly on characterizing the sub-pixel configuration to allow for any sub-pixel configuration to be controlled by a couple of parameters that can be changed depending on which display that the combined stereoscopic image signals is to be displayed.

Abstract: A display device (500) comprises a micro-display (22) and imaging optics (24) to transmit a light beam (BO), and a diffractive beam expander (10) having an output grating (16). The combination of said micro-display (22) and said imaging optics (24) is together adapted to form a virtual image (710) which is observable through the perimeter (15) of said output grating (16) when said diffractive beam expander (10) is positioned to at least partially intercept said light beam (BO). The combination of said micro-display (22) and said imaging optics (24) may also be adapted to project said light beam (BO) onto an external screen (600) in order to display a real image (610). The display device (500) may comprise a movable optical component (10, 380) to switch the device (500) from a virtual display mode to a projecting mode.

Abstract: For supporting a three-dimensional presentation on a display, which presentation combines at least a first available image and a second available image, differences between a first calibration image and a second calibration image are detected. At least one of a first available image and a second available image are then modified to approach desired disparities between the first available image and the second available image based on the detected disparities between the first calibration image and the second calibration image.
