20100253768 | APPARATUS AND METHOD FOR GENERATING AND DISPLAYING A STEREOSCOPIC IMAGE ON A MOBILE COMPUTING DEVICE - 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. | 10-07-2010 |
20110025822 | METHOD AND DEVICE FOR REAL-TIME MULTI-VIEW PRODUCTION - 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. | 02-03-2011 |

20140347444 | METHOD AND DEVICE FOR STEREO BASE EXTENSION OF STEREOSCOPIC IMAGES AND IMAGE SEQUENCES - 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. These synthetic perspectives are calculated only on the basis of a disparity map, which is supplied or which is calculated in a preprocessing step. In this case, the method presented solves the following problems: 1. Calculation of the new extension perspectives, 2. Correct repositioning of the camera perspectives supplied within the visual zones, 3. Definition of which disparities are intended to be continued in the case of collision in the extension and 4. Interpolation of the image regions which become visible as a result of the extension of the stereo base. In this case, instances of left and right masking are also identified and optically correctly maintained and supplemented in the extension perspectives. | 11-27-2014 |
