| 20090167639 | METHODS OF REDUCING PERCEIVED IMAGE CROSSTALK IN A MULTIVIEW DISPLAY - Methods of reducing perceived image crosstalk in a multiview display. One method includes providing an image stream to a display having a horizontal dimension that extends from a first side of the display to an opposing second side of the display. The image stream includes a temporal sequence of images where at least a first image view and then a second image view are displayed on the display in a time sequential manner. The temporal sequence of images are conditioned before being displayed in order to reduce perceived displayed image crosstalk between the first and second image views. The conditioning includes modifying a color intensity of at least selected pixels along the horizontal dimension based on a non-constant crosstalk correction function for the horizontal dimension. | 07-02-2009 |
