    Abstract: A method for 2D/3D switchable displaying includes: real-time detecting a 3D display area; when a change of the 3D display area is detected, calculating a gradient coefficient based on a number of frame of change and a rate of the change of the 3D display area; adjusting a 3D image area and a 3D grating area based on the calculated gradient coefficient; and performing a stereoscopic display by the adjusted 3D image area and the adjusted 3D grating area. When the 3D display area starts a change and ends the change, the 3D display area gradually is switched to be 2D display and switched to be 3D display respectively, so that a gradient visual effect is achieved, and the problems of viewing image jitter and 3D effect mistake caused by pixel arrangement and hardware control in the 3D display area being not synchronized can be avoided.

  • Publication number: 20150124062
    Abstract: Multi-view autostereoscopic displays provide an immersive, glasses-free 3D viewing experience, but they preferably use correctly filtered content from multiple viewpoints. The filtered content, however, may not be easily obtained with current stereoscopic production pipelines. The proposed method and system takes a stereoscopic video as an input and converts it to multi-view and filtered video streams that may be used to drive multi-view autostereoscopic displays. The method combines a phase-based video magnification and an interperspective antialiasing into a single filtering process. The whole algorithm is simple and may be efficiently implemented on current GPUs to yield real-time performance. Furthermore, the ability to retarget disparity is naturally supported. The method is robust and works transparent materials, and specularities. The method provides superior results when compared to the state-of-the-art depth-based rendering methods.

    Abstract: The invention concerns a method and a device for correcting distortion errors in a 3D content viewed by an observer on a screen. The method comprises the step of determining a rendered roundness factor (ITO of a pinhole model projected cylinder, estimating a rendered roundness factor table depending on the defined distance of the observer to the screen and the disparity values of objects of the image, determining for the observer a disparity transform function (TD) as a function of the estimated rendered roundness factor table and modifying the object disparity values using the disparity transform so that a perceived roundness factor of one is provided.

  • Publication number: 20150085076
    Abstract: Approaches enable image content (e.g., still or video content) to be displayed to provide a viewer with an appearance or view of the content that is based at least in part upon a current relative position and/or orientation of the viewer with respect to the device, as well as changes in that relative position and/or orientation. For example, positional data can be used to render image content from a perspective that is consistent with a viewing angle for the current relative position of the viewer. As that viewing angle changes, the content can be re-rendered or otherwise updated to display the image content from a perspective that reflects the change in viewing angle. The content can include various portions, and different adjustments can be applied to each portion based upon these and/or other such changes.
