摘要：A time-of-flight (TOF) imaging system includes illumination circuitry, such as alaser, one or more sensors, such as SPAD arrays, and image processing circuitry. Theillumination circuitry illuminates one or more objects in an environment around the TOF

imaging system. The sensors generate an image data stream based on reflections fromthe one or more illuminated objects, and possibly based on reflections from one or morereflectors. The image processing circuitry generates counts associated with distancesbased on the image data stream and possibly a reflection data stream and stores thegenerated counts in a histogram using a plurality of bins. Each of the plurality of binsstores counts associated with a respective distance range. A size of a bin in the pluralityof bins is a function of the respective distance range, and may be based on a logarithmicfunction of the distance associated with the bin.
