Publication number: 20230092325Abstract: In one example, an apparatus comprises a first photodiode, a second photodiode, a first floating diffusion, a second floating diffusion, a quantizer, and a controller. The controller can enable the first photodiode and the second photodiode to generate and accumulate photo charge within an exposure period, and use the quantizer to quantize reset voltages at the first floating diffusion and at the second floating diffusion to generate a first digital reset value and a second digital reset value. After the exposure period ends, the controller can transfer the photo charge from the first photodiode and the second photodiode to, respectively, the first floating diffusion and the second floating diffusion to generate a first signal voltage and a second signal voltage, and quantize the signal voltages into digital signal values using the quantizer. Digital representations can be generated based on the digital reset values and the digital signal values.Type: ApplicationFiled: September 9, 2022Publication date: March 23, 2023Inventors: Tsung-Hsun Tsai, Song Chen, Lyle David Bainbridge, Xinqiao Liu

Patent number: 11076143Abstract: A system detects a screen tear in a display device for frames of video by retrieving an identification code associated with each pixel row of the frame of video and analyzing identification codes across the pixel rows of the frame of the video to detect occurrence of a screen tear. To support compressed (e.g., lossy) video data, the identification code associated with each pixel row of the frame of video is inserted into the most significant bit (or bits) of a color channel of a first pixel of the pixel row. Identification codes across the pixel rows of the frame of the video are then compared for tear detection. Because modification of the most significant bit of a color channel of a pixel may result in color distortion, the pixels including inserted identification codes are hidden from view by the display device.Type: GrantFiled: December 12, 2017Date of Patent: July 27, 2021Assignee: Facebook Technologies, LLCInventor: Lyle David Bainbridge

Patent number: 10652539Abstract: A video coder is configured to encode video data, wherein one or more pixels of the encoded video data is used to signal in-band a luminance adjustment value for configuring an overall luminance of the displayed video data. In addition, the video data for pixels of the video data are scaled based upon the luminance adjustment value to compensate for the changed overall luminance. By signaling the luminance adjustment value in-band as part of the encoded video data, the need for a separate control channel is reduced, while also simplifying synchronization between the luminance adjustment value and the frame of video data to which it applies. The display may extract and parse the signaled luminance adjustment value to control a parameter of the display device (e.g., driving voltage, supply current, duty cycle, etc.) to achieve the overall luminance level indicated by the luminance adjustment value.Type: GrantFiled: July 31, 2017Date of Patent: May 12, 2020Assignee: Facebook Technologies, LLCInventors: Nirav Rajendra Patel, Lyle David Bainbridge, Sandro Pintz

Patent number: 10433307Abstract: A head-mounted display (HMD) is wirelessly coupled to a console or a relay depending on the relative positions of the HMD, the console, and the relay. The HMD communicates wirelessly with the console using a beam that is oriented in a particular direction. As the position of the HMD changes, the quality of the communication link between the HMD and the console may degrade. In response to the degradation, the HMD forms a communication link with a relay, which operates as an intermediary between the HMD and the console. The relay communicates with the HMD over a dedicated communication channel that is isolated from the communication channel over which the relay communicates with the console.Type: GrantFiled: April 20, 2017Date of Patent: October 1, 2019Assignee: Facebook Technologies, LLCInventors: Qi Qu, Hongyu Zhou, Ganesh Venkatraman, Ryan Hamilton Brown, Lyle David Bainbridge, Sam Padinjaremannil Alex, Ali Yazdan, Nirav Rajendra Patel

Patent number: 10356407Abstract: Embodiments relate to a method and a system for performing image compression and decompression of image data. In one or more embodiments, the image data is divided into one or more image data blocks, and the image compression and decompression are performed for each image data block. The image data block is compressed and includes a base value corresponding to a first image component and a compressed difference value corresponding to a second image component. For decompression, a first value of the image data block can be obtained based on the base value, and a second value of the image data block can be obtained based on the first value, the first compressed difference value and a corresponding quantization table. An output image can be presented to a user, according to the decompressed image data block.Type: GrantFiled: July 29, 2016Date of Patent: July 16, 2019Assignee: Facebook Technologies, LLCInventors: Andrew Thomas Forsyth, Lyle David Bainbridge
