  • Publication number: 20200314376
    Abstract: An imaging device is described which, in some examples, includes general pixels and phase difference pixels. The general pixels, when operated by control signals, receive light from a subject and generate currents or voltages that are measured; a depth is estimated based on the measurements. The phase difference pixels generate currents based on a switched charge source. Data obtained from the currents generated by the phase difference pixels is used to adjust the control signals and thereby improve an accuracy of the depth estimation.

  • Publication number: 20200256991
    Abstract: An image sensor includes a plurality of pixels and photo gate controller circuitry. Each pixel may transmit a pixel signal, corresponding to a photoelectric signal, in response to a photo gate signal in a frame. The photo gate controller circuitry may generate photo gate signals and transmit photo gate signals to the pixels. The photo gate controller circuitry includes a first delay circuit configured to transmit first delay clock signals each being delayed with respect to a reference clock signal by a certain amount of time and a second delay circuit configured to transmit second delay clock signals each being delayed with respect to the reference clock signal by a certain amount of time. The pixels are each configured to selectively receive signals, as the photo gate signals, among the delay clock signals output from the first delay circuit and the delay clock signals output from the second delay circuit.

  • Patent number: 10733760
    Abstract: A Dynamic Vision Sensor (DVS) pose-estimation system includes a DVS, a transformation estimator, an inertial measurement unit (IMU) and a camera-pose estimator based on sensor fusion. The DVS detects DVS events and shapes frames based on a number of accumulated DVS events. The transformation estimator estimates a 3D transformation of the DVS camera based on an estimated depth and matches confidence-level values within a camera-projection model such that at least one of a plurality of DVS events detected during a first frame corresponds to a DVS event detected during a second subsequent frame. The IMU detects inertial movements of the DVS with respect to world coordinates between the first and second frames. The camera-pose estimator combines information from a change in a pose of the camera-projection model between the first frame and the second frame based on the estimated transformation and the detected inertial movements of the DVS.
