Abstract: An autostereoscopic display system includes a transmissive display panel including a backlight having an array of backlight pixels, a selectively-selectively-transmissive display pixel matrix having a first side facing the backlight and an opposing second side, the selectively-transmissive display pixel matrix comprising an array of display pixels, a first lenticular array disposed between the backlight and the first side of the selectively-transmissive display pixel matrix, and a second lenticular array disposed facing the second side of the selectively-transmissive display pixel matrix. The backlight is configured to separately activate different subsets of the backlight pixels such that light emitted from an activated subset of backlight pixels and transmitted through the first lenticular array, the selectively-transmissive display pixel matrix, and the second lenticular array is emitted by the display panel as display light in a corresponding separate direction relative to the display panel.

Abstract: A display system including a tracking subsystem configured to track one of a pose of a head of a viewer or a pose of an eye of the viewer. The display system further includes an image correction module configured to, for each pixel of at least a subset of pixels of an input image, determine a pixel view angle for the pixel based on the pose of the head or the pose of the eye, determine a corrected pixel value based on an input pixel value of the pixel in the input image and based on the pixel view angle; and provide the corrected pixel value for the pixel in an angle-corrected image corresponding to the input image. The display system further includes a display panel to display the angle-corrected image.

Abstract: An example telepresence terminal includes a lenticular display, an image sensor, an infrared emitter, and an infrared depth sensor. The terminal may determine image data using visible light emitted by the infrared emitter and captured by the image sensor and determine depth data using infrared light captured by the infrared depth sensor. The terminal may also communicate the depth data and the image data to a remote telepresence terminal and receive remote image data and remote depth data. The terminal may also generate a first display image using the lenticular display based on the remote image data that is viewable from a first viewing location and generate a second display image using the lenticular display based on the remote image data and the remote depth data that is viewable from a second viewing location.
