Patent number: 10225540Abstract: A method for the autostereoscopic representation of images on a display screen includes the steps of selecting a view mode from a plurality of pre-defined view modes; creating a channel mask that defines a number N of channels per segment of the optical plate, wherein N is larger than or equal to the number of views in the selected view mode; providing a texture for each of the N channels; correlating each screen pixel with at least one texture by reference to the channel mask; applying an allocation algorithm for allocating the total of the image information to be displayed at a time to at least two textures such that each texture includes the information for one view.Type: GrantFiled: December 30, 2015Date of Patent: March 5, 2019Assignee: SeeFront GmbHInventor: Christoph Grossmann

Patent number: 9952426Abstract: A method of constructing a channel mask for an autostereoscopic display, the display including an electronically controlled screen covered by a parallax filter device that includes a refractive medium and is configured to obscure certain areas on the screen for a left eye of a viewer and to obscure certain other areas on the screen for a right eye of the viewer, the channel mask being a two-dimensional geometric object that permits to assign to each point on the screen one of a number of viewing positions of an eye of the viewer, the method including the step of constructing the channel mask by tracing light rays that propagate from selected points on the screen and are refracted at the parallax filter device.Type: GrantFiled: May 28, 2015Date of Patent: April 24, 2018Assignee: SeeFront GmbHInventor: Christoph Grossmann

Patent number: 9019354Abstract: A method for calibrating an autostereoscopic display system, having the steps of detecting a camera viewing position (P) of a camera (16; 116) arranged to be able to observe a display (22) of the autostereoscopic display system (S12), providing and displaying on the display (22) in an autostereoscopic display mode of the display (22) a test pattern including different image information for at least two laterally displaced respective viewing positions (28; 32) in front of the display (22), of which viewing positions at least one is based on the detected camera viewing position (P), based on system parameters of the autostereoscopic display system (S14, S16), and adjusting at least one of the system parameters based on a camera image of the test pattern as observed by the camera (16; 116) (S22).Type: GrantFiled: February 17, 2012Date of Patent: April 28, 2015Assignee: SeeFront GmbHInventor: Christoph Grossmann

Patent number: 8077195Abstract: A method for the autostereoscopic representation of images on a screen, wherein image information of separate channels for a right eye and a left eye of a user is displayed in interleaved segments on the screen, and a lens array is disposed for deflecting light emitted from the screen such that the image information of each channel is visible only for one eye of the user, including the steps of defining a channel mask, as determined by the lens array, projecting the channel mask onto the screen, thereby to assign to each pixel of the screen a correlation with at least one of the channels, storing, for each channel, and determining the contents of each pixel on the basis of its correlations with the channels.Type: GrantFiled: July 24, 2006Date of Patent: December 13, 2011Assignee: SeeFront GmbHInventor: Christoph Groβmann
