Abstract: An imaging device includes at least a first group of pixels. A driver block is configured to generate at least two shutter signals, each having on-phases periodically alternating with off-phases. The shutter signals might not be in phase. The imaging device may have an optical shutter that is partitioned in two or more parts, or a set of two or more optical shutters. The shutter parts, or the shutters, may receive the shutter signals, and accordingly open and close. A design of the driver block requires reduced power, which is highly desirable for mobile applications. Moreover, 3D imaging may be implemented that uses various time-of-flight configurations.

Abstract: A method and a system are disclosed that use a double-readout technique to generate timestamps and grayscale values for pixel-specific outputs of a pixel row in a pixel array in which the pixel array forms an image plane and the row of pixels forms an epipolar line of a scanning line on the image plane. For a pixel-specific output that exceeds a threshold, a timestamp value and a grayscale value are generated and associated with the pixel-specific output. If a pixel-specific output does not exceed the threshold and no timestamp is generated (i.e., a missing timestamp), a grayscale value for the pixel-specific output is generated and associated with the pixel-specific output. Timestamps errors may be corrected that may be caused by missing timestamps, timestamps that are associated with pixel clusters and outlier timestamps, i.e., pixel-specific outputs that are not consistent with a monotonic relationship of timestamp values under normal conditions.

A first region of nanostructures directs a first field of view (FOV) of light incident on the first region of nanostructures to a first region of an image plane. A second region of nanostructures directs a second FOV of light incident on the second region of nanostructures to a second region of the image plane in which the second FOV is different from the first FOV, and the second region of the image plane is different from the first region of the image plane. A third region of nanostructures directs a third FOV of light to a third region of the image plane, in which the third FOV is different from the first FOV and the second FOV, and the third region of the image plane is different from the first region and the second region of the image plane.

Abstract: A pixel for an image sensor includes a photon sensor, a memory, and an accumulator. The photon sensor element portion outputs a signal to an accumulator, which then may add value stored in memory together and may transfer the result to the memory of another pixel. The pixel may be analog or digital and may be used in a pixel array for compressed sensing imaging. During imaging, a pseudo-random mask may also be used. The data collected during imaging may be used in compressed sensing and may be sent to an offline storage to be processed.

Abstract: A computing device includes a system that authenticates a user of the computing device. A first sensor obtains a first representation of a physical characteristic of the user that is compared to a registered representation of the physical characteristic of the user. A first level of access to the computing device is enabled based on the first representation of the physical characteristic matching the second representation of the physical characteristic. A second sensor obtains a first representation of a liveness characteristic of the user that indicates that the user is alive. The first representation of the liveness characteristic is compared to a registered representation of the liveness characteristic of the user. A second level of access to the computing device is enabled based on the first representation of the liveness characteristic of the user matching the second representation of the liveness characteristic of the user.

Abstract: Using the same image sensor to capture a two-dimensional (2D) image and three-dimensional (3D) depth measurements for a 3D object. A laser point-scans the surface of the object with light spots, which are detected by a pixel array in the image sensor to generate the 3D depth profile of the object using triangulation. Each row of pixels in the pixel array forms an epipolar line of the corresponding laser scan line. Timestamping provides a correspondence between the pixel location of a captured light spot and the respective scan angle of the laser to remove any ambiguity in triangulation. An Analog-to-Digital Converter (ADC) in the image sensor operates as a Time-to-Digital (TDC) converter to generate timestamps. A timestamp calibration circuit is provided on-board to record the propagation delay of each column of pixels in the pixel array and to provide necessary corrections to the timestamp values generated during 3D depth measurements.

Abstract: An imaging unit includes a light source and a pixel array. The light source projects a line of light that is scanned in a first direction across a field of view of the light source. The line of light oriented in a second direction that is substantially perpendicular to the first direction. The pixel array is arranged in at least one row of pixels that extends in a direction that is substantially parallel to the second direction. At least one pixel in a row is capable of generating two-dimensional color information of an object in the field of view based on a first light reflected from the object and is capable of generating three-dimensional (3D) depth information of the object based on the line of light reflecting from the object. The 3D-depth information includes time-of-flight information.
