Abstract
Techniques for resolving a range to an object using histograms are disclosed. A frame collection time for a depth-image frame is divided into a plurality of different collection subframes, where each collection subframe encompasses a plurality of light pulse cycles. Counts of accumulated photon detections by a pixel during the different collection subframes are allocated to histogram bins using different bin maps for the collection subframes. Each bin map defines a different mapping of time to bins for the light pulse cycles within its applicable collection subframe, and each mapping defines a bin width for its bins so that its bin map covers a maximum detection range for the depth-image frame. A range to an object in the pixel's field of view (within the maximum detection range) can be resolved according to a combination of peak bin positions in the histogram data with respect to the different collection subframes.
