Patent number: 11758075Abstract: A display system arranged to receive a video stream of frames for display. The frame rate of the video stream is defined by a first clock signal comprising a plurality of first clock reset signals (between frames). A subframe rate of the display system is defined by a second clock signal comprising a plurality of second clock reset signals (between subframes). The second clock reset signals define n subframes for each frame of the video stream. That is, the subframe rate of the display system is n times faster than the frame rate of the video stream. The display system is arranged so that duration of every nth second clock reset signal is different to the duration of the other second clock reset signals such that synchronization between frames of the video stream and subframes of the display device is maintained.Type: GrantFiled: April 30, 2021Date of Patent: September 12, 2023Assignee: Dualitas LtdInventor: Stig Mikael Collin

Patent number: 11722650Abstract: An image processing engine and method of forming a hologram of a target image for projection using data streaming. An input or primary image is sub-sampled using a kernel and the secondary image output used to generate a hologram of the target image. A technique of kernel sub-sampling using a plurality of two or more data streams provides improvements in efficiency, including reduced data storage requirements and increased processing speed.Type: GrantFiled: April 30, 2021Date of Patent: August 8, 2023Assignee: ENVISICS LTDInventor: Stig Mikael Collin

Patent number: 11531200Abstract: A logic circuit that can output a stream of sequential values, representing pixel position values, for a pixelated display device such as a spatial light modulator. The logic circuit may comprise an advanced integrated circuit such as a field-programmable gate array (FPGA) or an application-specific integrated circuit (ASIC). The stream of sequential values that is output by the logic circuit can be used by another logic circuit to calculate corresponding values of a software function, for populating those pixels of the pixelated display device. The software function can be, for example, a lens function or a grating function, which might be combined with a hologram, such as a computer-generated hologram (CGH), for display on the pixelated display device.Type: GrantFiled: March 30, 2021Date of Patent: December 20, 2022Assignee: DUALITAS LTDInventor: Stig Mikael Collin

Patent number: 11480919Abstract: A holographic projector comprises an image processing engine, a hologram engine, a display engine and a light source. The image processing engine is arranged to receive a source image for projection and generate a plurality of secondary images from the source image. The source image comprises pixels. Each secondary image comprises fewer pixels than the source image. A first secondary image has more pixels that a second secondary image. The hologram engine is arranged to determine, such as calculate, a hologram corresponding to each secondary image to form a plurality of holograms. Thus, a first hologram corresponding to the first secondary image has more pixels than a second hologram corresponding to the second secondary image. The display engine is arranged to display each hologram in turn on the display device. The light source is arranged to Illuminate each hologram during display to form a holographic reconstruction corresponding to each secondary image on a replay plane.Type: GrantFiled: August 24, 2020Date of Patent: October 25, 2022Assignee: DUALITAS LTDInventors: Michal Wengierow, Mikael Collin, Sahar Chowdhury

Publication number: 20210141221Abstract: A logic circuit comprising a logic sub-circuit arranged to output a stream, S1, of Fresnel lens values, F(x), of a Fresnel lens for display on [m×n] pixels of a pixelated display device. In a first step, the logic circuit is arranged to set an initial data value stored in a first data register unit of the logic sub-circuit to (a?k)2 and set an initial data value stored in a second data register unit of the logic sub-circuit to a2?(a?k)2. In a second step the logic circuit is arranged to read the initial data value stored in the first data register unit and the initial data value stored in the second data register unit in a first iteration, and to read the data value stored in the first data register unit in the preceding iteration and the data value stored in the second data register unit in the preceding iteration, in a further iteration.Type: ApplicationFiled: November 13, 2020Publication date: May 13, 2021Inventor: Mikael Collin
