    摘要： 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.

    摘要翻译： 本发明涉及一种用于改善立体图像和图像序列的深度印象的方法和装置。 在自动立体多观察者显示装置中，通常产生多个中间视角，这导致观看者感知到的立体声降低。 在本应用中呈现的立体声基础拓宽导致了显着的改进，从而获得了更逼真的深度印象。 它可以在相机中录制过程中实现，也可以集成到显示设备中。 深度印象的改善是通过生成在相机透镜的观察方向上位于左，右右记录摄像机左侧和右侧的合成透视图，在右侧和右侧延长连接线 形成了极左和极右相机的视角。 这些合成透视图只是根据提供的视差图或在预处理步骤中计算的视差图来计算的。 在这种情况下，提出的方法解决了以下问题：1.计算新的扩展视角，2.正确重新定位视觉区域内提供的摄像机视角，3.定义在以下情况下将继续存在哪些差异 扩展中的碰撞和4.由于立体声基座的延伸而变得可见的图像区域的插值。 在这种情况下，还会识别左右掩蔽的实例，并在扩展视角中进行光学正确维护和补充。

    摘要： 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.

    摘要： 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.

    摘要： 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.
