  • Patent number: 11856301
    Abstract: There is provided a method and system for extending image sensor dynamic range using coded pixels. The method including: providing pixel codes to pixels in the photodetector array for each subframe of a frame; receiving a sensor readout of each of the pixels in the photodetector array for each subframe; for each subframe, based on the pixel code, routing each sensor readout value for collection at one or more taps or to a drain; combining the collected sensor readout values at each of the taps to determine a single pixel value for the frame; and outputting the single pixel value for each pixel for the frame.
    Type: Grant

  • Patent number: 11425357
    Abstract: Energy-efficient epipolar imaging is applied to the ToF domain to significantly expand the versatility of ToF sensors. The described system exhibits 15+ m range outdoors in bright sunlight; robustness to global transport effects such as specular and diffuse inter-reflections; interference-free 3D imaging in the presence of many ToF sensors, even when they are all operating at the same optical wavelength and modulation frequency; and blur- and distortion-free 3D video in the presence of severe camera shake. The described embodiments are broadly applicable in consumer and robotics domains.

  • Publication number: 20210274085
    Abstract: A method comprising receiving data representing light intensity values corresponding to a flicker pattern of a reference light source powered by an alternating current (AC); operating a controllable illumination source, based, at least in part, on said data; capturing, using an imaging device, a sequence of images of a scene illuminated, at least in part, by said controllable illumination source; estimating an intensity value for at least one pixel in said array, correspondingly in each of said images in said sequence of images; and determining a temporal point in said flicker pattern of said reference light source, based, at least in part, on said estimating.
