  • Patent number: 10681356
    Abstract: Approaches to selection of motion vector (“MV”) precision during video encoding are presented. These approaches can facilitate compression that is effective in terms of rate-distortion performance and/or computational efficiency. For example, a video encoder determines an MV precision for a unit of video from among multiple MV precisions, which include one or more fractional-sample MV precisions and integer-sample MV precision. The video encoder can identify a set of MV values having a fractional-sample MV precision, then select the MV precision for the unit based at least in part on prevalence of MV values (within the set) having a fractional part of zero. Or, the video encoder can perform rate-distortion analysis, where the rate-distortion analysis is biased towards the integer-sample MV precision. Or, the video encoder can collect information about the video and select the MV precision for the unit based at least in part on the collected information.

  • Patent number: 10681295
    Abstract: A time of flight camera includes a light source, a first pixel, a time-to-digital converting, and a controller. The light source is configured to emit light towards an object to be reflected back to the time of flight camera as image light. The first pixel includes a photodetector to detect the image light and to convert the image light into an electric signal. The time-to-digital converter is configured to generate timing signals representative of when the light source emits the light and when the photodetector detects the image light. The controller is coupled to the light source, the first pixel, and the time-to-digital converter. The controller includes logic that when executed causes the time of flight camera to perform operations. The operations include determining a detection window for a round-trip time of the image light based, at least in part, on the timing signals and first pulses of the light.
