Publication/Patent Number: US2020288093A1 Publication Date: 2020-09-10 Application Number: 16/650,545 Filing Date: 2018-09-24 Inventor: Pertierra, Juan P.   Richards, Martin J.   Orlick, Christopher John   Le, Barbenchon Clement   Pires, Arrifano Angelo M.   Assignee: DOLBY LABORATORIES LICENSING CORPORATION   DOLBY INTERNATIONAL AB   IPC: H04N9/31 Abstract: A novel high efficiency image projection system includes a beam-steering modulator, an amplitude modulator, and a controller. In a particular embodiment the controller generates beam-steering drive values from image data and uses the beam-steering drive values to drive the beam-steering modulator. Additionally, the controller utilizes the beam-steering drive values to generate a lightfield simulation of a lightfield projected onto the amplitude modulator by the beam-steering modulator. The controller utilizes the lightfield simulation to generate amplitude drive values for driving the amplitude modulator in order to project a high quality version of the image described by the image data.
