摘要： Lightfield displays for generating a 3D image comprise a 2D array of hogels. Each hogel comprises a 2D array of one or more pixels for generating light rays, and a light distribution control arrangement for controlling in 2D the angular distribution of the light rays from the array which are emitted by the hogel. The 2D array of each hogel is arranged to generate light rays which correspond to an elementary image assigned to the hogel, with each elementary image having a central axis which passes through a center of the image and extends perpendicular to the image. A plurality of the hogels have different lateral offsets between the light distribution control arrangement and the central axis of the respective elementary image.

摘要： The present invention is an improvement in dynamic autostereoscopic visual displays emitting a field of light beams into an observer viewing space from a hogel array formed at a transparent projection screen surface having refractive beam expanding functions. The transparent screen is illuminated from the rear by an X-Y array of projectors focused on the screen, where each hogel location is illuminated by a local group of multiple projectors within the larger array. The brightness, color and direction of the light beams emitted by each hogel are controlled by one image point in each member of the local projector group that illuminates that hogel. The invention enables autostereoscopic display systems with compact dimensions and high overall resolution and brightness by combining the output of an array of small projectors with lower resolution and brightness on a single projection screen.

摘要： A method and apparatus of displaying a magnified image comprising obtaining an image of a scene using a camera with greater resolution than the display, and capturing the image in the native resolution of the display by either grouping pixels together, or by capturing a smaller region of interest whose pixel resolution matches that of the display. The invention also relates to a method whereby the location of the captured region of interest may be determined by external inputs such as the location of a person's gaze in the displayed unmagnified image, or coordinates from a computer mouse. The invention further relates to a method whereby a modified image can be superimposed on an unmodified image, in order to maintain the peripheral information or context from which the modified region of interest has been captured.
