    Abstract: Techniques and systems are provided for high resolution time-of-flight (ToF) depth imaging. In some examples, an apparatus includes a projection system including one or more light-emitting devices, each light-emitting device being configured to illuminate at least one portion of an entire field-of-view (FOV) of the projection system. The entire FOV includes a plurality of FOV portions. The apparatus also includes a receiving system including a sensor configured to sequentially capture a plurality of images based on a plurality of illumination reflections corresponding to light emitted by the one or more light-emitting devices. Each image of the plurality of images corresponds to one of the plurality of FOV portions. An image resolution associated with each image corresponds to a full resolution of the sensor. The apparatus further includes a processor configured to generate, using the plurality of images, an increased resolution depth map associated with the entire FOV.

    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 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.
