Abstract: Depth and imaging pixels include Single-Photon Avalanche Diode (SPAD) micropixels. A memory stores histogram data and intensity data. Timed memory selection logic is configured to generate the histogram data and the intensity data.

Abstract: A projector for illuminating a target area is presented. The projector includes an array of emitters having a plurality of subarrays and an optical assembly. Each subarray includes one or more independently addressable channels emitting light in accordance with emission instructions. At least two of the subarrays are adjacent to each other and do not overlap. The optical assembly is configured to tile portions of the emitted light to form a light pattern for projection to a target area. The light pattern has a first plurality of sections and a second plurality of sections. Each section of the first plurality represents a first respective portion of the light pattern emitted from a corresponding subarray. Each section of the second plurality represents a second respective portion of the light pattern formed by tiling light emitted from two or more of the subarrays.

Abstract: A depth sub-frame is captured with a first region of depth pixels configured to image a first zone of a field illuminated by near-infrared illumination light. A visible-light sub-frame is captured with a second region of image pixels that is distanced from the first region of the depth pixels. The second region of the image pixels is configured to image a second zone of the field while the first region of the depth pixels images the first zone of the field while the near-infrared illumination light illuminates the first zone.

Abstract: A depth camera assembly includes an illuminator that dynamically illuminates different regions of a local area. The illuminator comprises an array of light sources, such as a vertical-cavity surface emitting laser (VCSEL) array, and a lens assembly. The array of light sources may include a plurality of groups of one or more light sources, with each group being independently addressable. The lens assembly is positioned so a focus of the lens assembly is in a plane where illumination from adjacent light sources of the array at least partially overlaps. Such positioning of the lens assembly focus causes light from adjacent light sources to blur into each other, forming flood illumination for a region of the local area. In some embodiments, the flood illumination may alternatively or additionally be achieved by introducing aberration into the lens assembly, including a microlens array in the illuminator or some combination thereof.

Abstract: A time-of-flight (ToF) module includes a light source, a driver module, and a light sensor. The driver module includes electrical circuitry configured to selectively drive the light source to emit pulsed illumination light. The light sensor is configured to sense returning light reflected from a target. At least one of the light source, driver module, and light sensor is stacked on another to reduce a footprint of the ToF module.
