  • Patent number: 11600010
    Abstract: A time-of-flight camera for generating a depth map indicating distance(s) to target(s) includes a processor and multi-pixel time-of-flight image sensor. The camera: (a) determines, at each pixel, a plurality of phase-correlation values associated with at least one exposure duration and at least one phase offset; (b) determines for each pixel an accumulated correlation in response to the plurality of phase-correlation values; and (c) generates the depth map in response to a plurality of the accumulated correlations. A set of accumulated correlations may be determined in response to a plurality of sets of phase-correlation values such that each accumulated correlation is associated with one unique phase offset in response to each set of phase-correlation values being associated with one exposure duration, the depth map being generated in response to a plurality of sets of accumulated correlations. A computer-implemented method of generating a depth map using a time-of-flight image sensor is provided.

  • Patent number: 9769451
    Abstract: Image processing is performed to facilitate subtractive crosstalk cancellation in 3D images. In a global embodiment, pixel values are compressed to provide sufficient foot room for subtractive crosstalk cancellation. For video images the degree of compression may vary from frame to frame. Temporal filtering may be applied to reduce flicker. In a local embodiment luminance is added to and/or compression is performed in local areas to facilitate more complete subtractive crosstalk cancellation. The amount or added luminance or compression may be matched to the requirements of the local areas. Added luminance and/or compression may be made to vary smoothly in time and smoothly in space. Displays and other apparatus may be constructed to perform methods for partial or complete crosstalk cancellation.
