Abstract: A structured-light pattern for a structured-light system includes a base light pattern that includes a row of a plurality of sub-patterns extending in a first direction. Each sub-pattern is adjacent to at least one other sub-pattern, and each sub-pattern is different from each other sub-pattern. Each sub-pattern includes a first number of portions in a sub-row and a second number of portions in a sub-column. Each sub-row extends in the first direction and each sub-column extends in a second direction that is substantially orthogonal to the first direction. Each portion may be a first-type portion or a second-type portion. A size of a first-type portion is larger in the first direction and in the second direction than a size of a second-type portion in the first direction and in the second direction. In one embodiment, a first-type portion is a black portion and the second-type portion is a white portion.

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.

Abstract: A time-resolving sensor includes a single-photon avalanche diode (SPAD), a logic circuit and differential time-to-charge converter (DTCC) circuit. The SPAD is responsive to a shutter signal to generate an output signal based on detecting an incident photon. The logic circuit generates first and second enable signals. The DTCC includes a capacitor device, first and second switching devices, and an output circuit. The first switching device is responsive to the first enable signal to transfer a charge on the capacitor device to the first floating diffusion. The second switching device is responsive to the second enable signal to transfer a remaining charge on the capacitor device to the second floating diffusion. The output circuit outputs a first voltage that is based on the first charge on the first floating diffusion and a second voltage that is based on the second charge on the second floating diffusion.

Abstract: A method is disclosed to determine a traveling time for a plurality of received light pulses that reflected and returned from an object. Each returned light pulse is associated with a timestamp indicating a time between a transmission time of a corresponding light pulse and a time of arrival of the returned light pulse. For each timestamp, a number C is determined of time stamps that are subsequent to the timestamp and within a predetermined time window after the timestamp. A maximum number C is determined, and an index i is determined for the maximum number C. A traveling time is determined for the plurality of light pulses as an average of the timestamp having a same index as the maximum number C and timestamps that are within the predetermined time window after the timestamp having the same index as the maximum number C.

Abstract: The Time-of-Flight (TOF) technique is combined with analog amplitude modulation within each pixel in an image sensor. The pixel may be a two-tap pixel or a one-tap pixel. Two photoelectron receiver circuits in the pixel receive respective analog modulating signals. The distribution of the received photoelectron charge between these two circuits is controlled by the difference (or ratio) of the two analog modulating voltages. The differential signals generated in this manner within the pixel are modulated in time domain for TOF measurement. Thus, the TOF information is added to the received light signal by the analog domain-based single-ended to differential converter inside the pixel itself. The TOF-based measurement of range and its resolution are controllable by changing the duration of modulation. An autonomous navigation system with these features may provide improved vision for drivers under difficult driving conditions like low light, fog, bad weather, or strong ambient light.

Abstract: A Time-of-Flight (TOF) technique is combined with analog amplitude modulation within each pixel in a pixel array using multiple Single Photon Avalanche Diodes (SPADs) in conjunction with a single Pinned Photo Diode (PPD) in each pixel. A SPAD may be shared among multiple neighboring pixels. The TOF information is added to the received light signal by the analog domain-based single-ended to differential converter inside the pixel itself. The spatial-temporal correlation among outputs of multiple, adjacent SPADs in a pixel is used to control the operation of the PPD to facilitate recording of TOF values and range of an object. Erroneous range measurements due to ambient light are prevented by stopping the charge transfer from the PPD—and, hence, recording a TOF value—only when two or more SPADs in the pixel are triggered within a pre-defined time interval. An autonomous navigation system with multi-SPAD pixels provides improved vision for drivers under difficult driving conditions.

Abstract: A system for calculating. A scratch memory is connected to a plurality of configurable processing elements by a communication fabric including a plurality of configurable nodes. The scratch memory sends out a plurality of streams of data words. Each data word is either a configuration word used to set the configuration of a node or of a processing element, or a data word carrying an operand or a result of a calculation. Each processing element performs operations according to its current configuration and returns the results to the communication fabric, which conveys them back to the scratch memory.

Abstract: Using the same image sensor to capture both a two-dimensional (2D) image of a three-dimensional (3D) object and 3D depth measurements for the 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 generates a multi-bit output in the 2D mode and a binary output in the 3D mode to generate timestamps. Strong ambient light is rejected by switching the image sensor to a 3D logarithmic mode from a 3D linear mode.
