Patent number: 11962778Abstract: A method of signaling additional chroma QP offset values that are specific to quantization groups is provided, in which each quantization group explicitly specifies its own set of chroma QP offset values. Alternatively, a table of possible sets of chroma QP offset values is specified in the header area of the picture, and each quantization group uses an index to select an entry from the table for determining its own set of chroma QP offset values. The quantization group specific chroma QP offset values are then used to determine the chroma QP values for blocks within the quantization group in addition to chroma QP offset values already specified for higher levels of the video coding hierarchy.Type: GrantFiled: April 20, 2023Date of Patent: April 16, 2024Assignee: Apple Inc.Inventors: Alexandros Tourapis, Guy Cote

Publication number: 20240096010Abstract: A device may include an electronic display to display an image frame based on blended image data and image processing circuitry to generate the blended image data by combining first image data and second image data via a blend operation. The blend operation may include receiving graphics alpha data indicative of a transparency factor to be applied to the first image data to generate a first layer of the blend operation. The blend operation may also include overlaying the first layer onto a second layer that is based on the second image data. Overlaying the first layer onto the second layer may include adding first pixels values of the first image data that include negative pixel values and are augmented by the transparency factor to second pixel values of the second image data to generate blended pixel values of the blended image data.Type: ApplicationFiled: September 21, 2022Publication date: March 21, 2024Inventors: Yun Gong, Jim C. Chou, Guy Cote

Publication number: 20230388468Abstract: In one embodiment, a system includes a first device rendering image data, a second device storing the image data, and a display panel that displays the image data stored in the memory. The first device renders multiple frames of the image data, compresses the multiple frames into a single superframe, and transports the single superframe. The second device receives the single superframe, decompresses the single superframe into the multiple frames of image data, and stores the image data on a memory of the second device.Type: ApplicationFiled: August 8, 2023Publication date: November 30, 2023Inventors: Yung-Chin Chen, Michael Bekerman, Guy Côté, Aleksandr M.

Patent number: 11823642Abstract: An electronic display pipeline may process image data for display on an electronic display. The electronic display pipeline may include burn-in compensation statistics collection circuitry and burn-in compensation circuitry. The burn-in compensation statistics collection circuitry may collect image statistics based at least in part on the image data. The statistics may estimate a likely amount of non-uniform aging of the sub-pixels of the electronic display. The burn-in compensation circuitry may apply a gain to sub-pixels of the image data to account for non-uniform aging of corresponding sub-pixels of the electronic display. The applied gain may be based at least in part on the image statistics collected by the burn-in compensation statistics collection circuitry.Type: GrantFiled: May 24, 2022Date of Patent: November 21, 2023Assignee: Apple Inc.Inventors: Mahesh B.

Publication number: 20230351672Abstract: A mixed reality system that includes a device and a base station that communicate via a wireless connection The device may include sensors that collect information about the user’s environment and about the user. The information collected by the sensors may be transmitted to the base station via the wireless connection. The base station renders frames or slices based at least in part on the sensor information received from the device, encodes the frames or slices, and transmits the compressed frames or slices to the device for decoding and display. The base station may provide more computing power than conventional stand-alone systems, and the wireless connection does not tether the device to the base station as in conventional tethered systems. The system may implement methods and apparatus to maintain a target frame rate through the wireless link and to minimize latency in frame rendering, transmittal, and display.Type: ApplicationFiled: June 29, 2023Publication date: November 2, 2023Applicant: Apple Inc.Inventors: Arthur Y.

Publication number: 20230336888Abstract: The present disclosure generally relates to systems and methods for image data processing. In certain embodiments, an image processing pipeline may be configured to receive a frame of the image data having a plurality of pixels acquired using a digital image sensor. The image processing pipeline may then be configured to determine a first plurality of correction factors that may correct each pixel in the plurality of pixels for fixed pattern noise. The first plurality of correction factors may be determined based at least in part on fixed pattern noise statistics that correspond to the frame of the image data. After determining the first plurality of correction factors, the image processing pipeline may be configured to configured to apply the first plurality of correction factors to the plurality of pixels, thereby reducing the fixed pattern noise present in the plurality of pixels.Type: ApplicationFiled: June 7, 2023Publication date: October 19, 2023Inventors: Guy Cote, D.

Patent number: 11590900Abstract: A ladder rack for supporting a ladder on a vehicle. The ladder rack comprises a supporting arrangement anchored only along a single edge area of a rooftop, the supporting arrangement comprising a first load-bearing member entirely extending over the rooftop within an edge of the rooftop and a second load-bearing member extending substantially parallel to the first load-bearing member with a lateral offset, outside the rooftop and away from the edge of the rooftop. A ladder-supporting arrangement holds the ladder and connects to the first load-bearing member and to the first load-bearing member for supporting a weight of the ladder. The remainder of the rooftop surface is exempt of any member and is free for other purposes. The ladder is held on a side of the vehicle with an offset to be able to open a sliding door on the same side of the vehicle as the ladder rack.Type: GrantFiled: August 21, 2020Date of Patent: February 28, 2023Assignee: Techno-Fab 9000 Inc.Inventor: Guy Cote
