Abstract: The invention relates to a display design wherein the space between the pixels of a display panel, the black matrix, is not magnified together with other content. The visibility of particularly smaller objects such as e.g. letters is thus increased.

Abstract: The invention relates to a method and a device for improving the depth impression of stereoscopic images and image sequences. In autostereoscopic multi-viewer display devices, generally a plurality of intermediate perspectives are generated, which lead to a reduced stereo base upon perception by the viewers. The stereo base widening presented in this application leads to a significant improvement and thus to a more realistic depth impression. It can either be effected during recording in the camera or be integrated into a display device. The improvement in the depth impression is achieved by the generation of synthetic perspectives situated, in the viewing direction of the camera lenses, on the left and right of the extreme left and extreme right recorded camera perspective on the right and left lengthening of the connection line formed by the extreme left and extreme right camera perspectives.

Abstract: From a stereo image having at least 2 perspectives additional virtual perspectives are produced, wherein the processing time for the virtual perspectives is less than a specified value and simultaneously the multi-view image quality is maximized by identifying image areas that have not changed between two stereo images of the image sequence. In these areas the associated disparity map also did not change and the disparity values are reused. In addition, the processing parameters for calculating the virtual perspectives are continuously adjusted through continuous time measurement during processing such that the quality is always at a maximum. An adaptive method is obtained, which is also able to respond to load fluctuations of the underlying hardware device.

Abstract: A method and a device for calibration (or “electronic” adjustment) of a display unit are provided and include a display and autostereoscopic adapter disc, particularly provided for fixing to the display. A method and a device for generation or playback of 3D images by the display unit including autostereoscopic adapter disc and display are also provided. Misalignment of the adapted disc with the display are compensated for by corresponding adjustment of the image display on the display.

Abstract: Methods and devices are disclosed, wherein from a stereo image having at least 2 perspectives additional (in general 8 or more) virtual perspectives can be produced, on condition that the time for the entire production process is less than the specified frame rate, and that simultaneously the multi-view image quality is maximized. It is not required that a disparity map exists. In general, the image regions that have not change between two stereo images of the image sequence are identified. In these regions, the associated disparity map also cannot have changed. In addition, the processing parameters are continuously adjusted through continuous time measurement during processing such that the quality is always at the maximum thereof. In this way, an adaptive method is obtained, which can also respond to load fluctuations of the underlying hardware device.

Abstract: An apparatus and method for generating and displaying a stereoscopic image on a mobile computing device. The apparatus includes an autostereoscopic overlay which is secured over at least a portion of the screen of the mobile computing device, such as by using a case. Computer-readable instructions are executed on the mobile computing device to align two captured images, if necessary, and interlace them into an interlaced image for subsequent display to the screen of the mobile computing device. When the displayed image is viewed by the user of the mobile computing device through the autostereoscopic overlay, the image appears as a stereoscopic (or three-dimensional) image.

Abstract: A method for generating three-dimensional images based on a sequence of two-dimensional images is characterized by the steps of: analyzing a two-dimensional image with respect to its scene type, selecting a deformation assigned to the defined scene type with which the two-dimensional image is deformed, deforming the two-dimensional image and transmitting the deformed two-dimensional image to at least one viewing channel. The method also contemplates applying various transition functions to the two-dimensional image to provide a continuous and smooth transition from one scene type to another. The method can be carried out by an apparatus for performing these functions.

Abstract: A method that improves compensation for hard cuts and/or vertical motion effects in the conversion of 2D images to 3D images, displays 2D images to one eye and computed images to the other eye. Generating the computed images includes using an approximation variable that represents some relationship between the 2D images, such as the speed of motion across two images. Compensating for the hard cut or vertical motion effect includes temporarily setting the approximation variable to a value that makes the left and right eye images more similar (if identical, displaying a 2D image). The approximation variable can be pre-set to a value based on the speed of motion in a scene to be displayed. A method of displaying images in either 2D or 3D may include converting 3D images to 2D images by displaying images computed from images intended for either the left eye or the right eye.

Abstract: A method and a device for generating 3D images, according to which an image of a second sequence of images is generated in addition to an image of a first sequence of 2D images at an interval that can be determined via an approximation variable (?). A measure of similarity (dk) between successive images of the first sequence is determined and compared with threshold values (?0<?1<?2) so as to modify the approximation variable (?) depending thereon in such a manner that the stereo base width does not turn unnaturally large. A phase analyzer (12) is used to determine a prevailing direction of movement in successive images of the first sequence of images and a phase converter (16) is used to allocate the image of the first and second sequence of images to a left-hand or right-hand viewing channel depending on a prevailing direction of movement in successive images of the first sequence.
