    Abstract: An embodiment method of operating an imaging device including a sensor array including a plurality of pixels, includes: capturing a first low-spatial resolution frame using a subset of the plurality of pixels of the sensor array; generating, using a processor coupled to the sensor array, a first depth map using raw pixel values of the first low-spatial resolution frame; capturing a second low-spatial resolution frame using the subset of the plurality of pixels of the sensor array; generating, using the processor, a second depth map using raw pixel values of the second low-spatial resolution frame; and determining whether an object has moved in a field of view of the imaging device based on a comparison of the first depth map to the second depth map.

    Abstract: A ToF sensor includes an array of pixels having first and second subsets of pixels, first and second pluralities of TDCs, a routing bus having first and second pluralities of bus drivers, and a controller configured to: when the first subset of pixels is active and the second subset of pixels is not active, control the first plurality of bus drivers to route events from half of the pixels of the first subset to the first plurality of TDCs and control the first and second pluralities of bus drivers to route events from the other half of the pixels of the first subset to the second plurality of TDCs, and when the first subset of pixels is not active and the second subset of pixels is active, control the first plurality of bus drivers to route events from the second subset of pixels to the first plurality of TDCs.

    Abstract: In an embodiment, a method includes: receiving a first plurality of digital codes from a TDC; generating a coarse histogram from the first plurality of digital codes; detecting a peak coarse bin from the plurality of coarse bins; after receiving the first plurality of digital codes, receiving a second plurality of digital codes from the TDC; and generating a fine histogram from the second plurality of digital codes based on the detected peak coarse bin, where a fine histogram depth range is narrower than a coarse histogram depth range, where a lower fine histogram depth is lower or equal to a lower coarse peak depth, and where a higher fine histogram depth is higher or equal to a higher coarse peak depth.
