Abstract: A video display system is configured to receive a sequence of image frames. Each frame is divided into a set of blocks. A center of mass is calculated for each block in a first frame and is saved for all blocks in the first frame. A center of mass is calculated for each block in a second frame. Motion between the first frame and the second frame is detected by comparing the center of mass of each block in the second frame to the center of mass of the corresponding block in the first frame, in which a still block is detected when a corresponding block in the first frame and the second frame have a same center of mass, and in which motion in a block is detected when a corresponding block in the first frame and the second frame have a different center of mass.

Abstract: Example apparatus described herein include a first circuit configured to slice an input image frame into input image slices, the first circuit including first outputs configured to output the input image slices. Described example apparatus also include digital light processing controllers (DLPCs) including first inputs coupled to the first outputs, the digital light processing controllers configured to process the input image slices to produce output image slices, the digital light processing controllers including second outputs configured to output the output image slices. Described example apparatus further include a second circuit including second inputs coupled to the second outputs, the second circuit configured to combine the output image slices to generate image frame data to provide to an input of a digital micromirror device (DMD).

Abstract: An apparatus includes an image sensor, a linear actuator, a projector coupled to the linear actuator, and a controller coupled to the image sensor and to the linear actuator. The controller is configured to determine a location of an eye of a user based on image data from the image sensor. The controller is further configured to activate the linear actuator to drive the projector to a position associated with projecting to the eye at the location. The controller is further configured to initiate projection, via the projector, of an image depicting a view of a three-dimensional scene, the image selected based on the location.

Abstract: A method includes determining a first location, within a first viewing window, of a first eye of a user based on image data from an image sensor. The first viewing window corresponds to a first projector of a plurality of projectors. The method further includes determining a second location, within a second viewing window, of a second eye of the user based on the image data. The second viewing window corresponds to a second projector of the plurality of projectors. The method further includes initiating projection, via the first projector, of a first image depicting a first view of a three-dimensional scene. The first image is selected based on the first location. The method further includes initiating projection, via the second projector, of a second image depicting a second view of the three-dimensional scene. The second image is selected based on the second location.
