    Abstract: Certain aspects relate to systems and techniques for full well capacity extension. For example, a storage capacitor included in the pixel readout architecture can enable multiple charge dumps from a pixel in the analog domain, extending the full well capacity of the pixel. Further, multiple reads can be integrated in the digital domain using a memory, for example DRAM, in communication with the pixel readout architecture. This also can effectively multiply a small pixel's full well capacity. In some examples, multiple reads in the digital domain can be used to reduce, eliminate, or compensate for kTC noise in the pixel readout architecture.

    Abstract: Aspects relate to an array camera exhibiting little or no parallax artifacts in captured images. For example, the planes of the central mirror surfaces of the array camera can be located at a midpoint along, and orthogonally to, a line between the corresponding camera location and the virtual camera location. Accordingly, the cones of all of the cameras in the array appear as if coming from the virtual camera location after folding by the mirrors. Each sensor in the array “sees” a portion of the image scene using a corresponding facet of the central mirror prism, and accordingly each individual sensor/mirror pair represents only a sub-aperture of the total array camera. The complete array camera has a synthetic aperture generated based on the sum of all individual aperture rays.

    Abstract: Systems and apparatus for a touch sensitive display device are disclosed. The display device may include a detachable transparent front panel which overlays a display panel. The detachable transparent front panel may be held against the display panel and a plurality of pressure sensors by a series of magnets. This allows the front panel to act as an interactive touch display system. By having a detachable transparent front panel, the touch sensitive display device may be placed in messy environments, such as a kitchen.

    Abstract: A method operational on a transmitter device is provided for projecting a composite code mask. A composite code mask on a tangible medium is obtained, where the composite code mask includes a code layer combined with a carrier layer. The code layer may include uniquely identifiable spatially-coded codewords defined by a plurality of symbols. The carrier layer may be independently ascertainable and distinct from the code layer and includes a plurality of reference objects that are robust to distortion upon projection. At least one of the code layer and carrier layer may be pre-shaped by a synthetic point spread function prior to projection. At least a portion of the composite code mask is projected, by the transmitter device, onto a target object to help a receiver ascertain depth information for the target object with a single projection of the composite code mask.

    Abstract: Aspects of the present disclosure relate to depth sensing using a device. An example device includes a light projector configured to project light in a first and a second distribution. The first and the second distribution include a flood projection when the device operates in a first mode and a pattern projection when the device operates in a second mode, respectively. The example device includes a receiver configured to detect reflections of light projected by the light projector. The example device includes a processor connected to a memory storing instructions. The processor is configured to determine first depth information based on reflections detected by the receiver when the device operates in the first mode, determine second depth information based on reflections detected by the receiver when the device operates in the second mode, and resolve multipath interference (MPI) using the first depth information and the second depth information.

    Abstract: Systems and techniques are described for large field of view digital imaging. A device's first image sensor captures a first image based on first light redirected from a first path onto a redirected first path by a first light redirection element, and the device's second image sensor captures a second image based on second light redirected from a second path onto a redirected second path by a second light redirection element. A virtual extension of the first path beyond the first light redirection element can intersect with a virtual extension of the second path intersect beyond the second light redirection element. The device can modify the first image and second image using perspective distortion correction, and can generate a combined image by combining the first image and the second image. The combined image can have a larger field of view than the first image and/or the second image.

    Abstract: A method and device is provided that compensates for different reflectivity/absorption coefficients of objects in a scene/object when performing active depth sensing using structured light. A receiver sensor captures an image of a scene onto which a code mask is projected. One or more parameters are ascertained from the captured image. Then a light source power for a projecting light source is dynamically adjusted according to the one or more parameters to improve decoding of the code mask in a subsequently captured image. Depth information for the scene may then be ascertained based on the captured image based on the code mask. In one example, the light source power is fixed at a particular illumination while an exposure time for the receiver sensor is adjusted. In another example, an exposure time for the receiver sensor is maintained/kept at a fixed value while the light source power is adjusted.
