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.

Abstract: A method for processing an image having a first bit depth includes performing two or more iterations of a bit depth enhancement operation that increases the bit depth of the image to a second bit depth that is higher than the first bit depth. The bit depth enhancement operation includes dividing the image into a plurality of areas, performing an edge detection operation to identify one or more areas from the plurality of areas that do not contain edge features, and applying a blur to the one or more areas from the plurality of areas that do not contain edge features. In a first iteration of the of the bit depth enhancement operation, the plurality of areas includes a first number of areas, and the number of areas included in the plurality of areas decreases with each subsequent iteration of the bit depth enhancement operation.

Abstract: An apparatus includes at least one camera and a refractor configured to change a direction of a light toward a lens of the camera. The refractor has a shape configured to redirect light representing an image at two focal points, the two focal points are on a same plane and at a same distance from the at least one camera, and the refractor is positioned between the two focal points and the at least one camera.

Abstract: The locations of pixels in a frame are adjusted at a display controller after the frame has been generated by a graphics processing unit (GPU) or other processor and provided to the display controller. The adjusting of the pixel locations therefore occurs as close as possible to a display panel in a display system, thereby supporting rapid changes to pixel positions.
