    Abstract: An electronic device includes at least one photodetection block, where the at least one photodetection block includes a plurality of macropixels arranged into an array. Each macropixel includes an array of photodiodes, with logic circuitry coupled to outputs of the array of photodiodes and configured to generate a detection signal as a function of logically combining the outputs of the array of photodiodes. Each macropixel has associated therewith selection circuitry configured to selectively pass the detection signal to output combining logic or to output combining logic of at least one neighboring macropixel of the plurality thereof. The output combining logic has inputs coupled to the selection circuitry and to the selection circuitry of the at least one neighboring macropixel, and is configured to generate an output detection signal as a function of logically combining outputs of the selection circuitry and the selection circuitry of the at least one neighboring macropixel.

    Abstract: A time-of-flight (TOF) imaging system includes illumination circuitry, such as a laser, one or more sensors, such as SPAD arrays, and image processing circuitry. The illumination circuitry illuminates one or more objects in an environment around the TOF imaging system. The sensors generate an image data stream based on reflections from the one or more illuminated objects, and possibly based on reflections from one or more reflectors. The image processing circuitry generates counts associated with distances based on the image data stream and possibly a reflection data stream and stores the generated counts in a histogram using a plurality of bins. Each of the plurality of bins stores counts associated with a respective distance range. A size of a bin in the plurality of bins is a function of the respective distance range, and may be based on a logarithmic function of the distance associated with the bin.

    Abstract: A method can be used for controlling pixel scanning within a range detector. A spatially controllable point light source generates a first series of light source pulses associated with a first spatial direction. The first series of light source pulses are generated during a first time period. The spatially controllable point light source generates a second series of light source pulses associated with a second spatial direction. The second series of light source pulses are generated during a second time period that overlaps with the first time period so that the second series of light source pulses are started during the first series of light source pulses.

    Abstract: A pixel circuit includes a single photon avalanche diode (SPAD) and a measurement circuit including a capacitance. The circuit is operable to discharge a known portion of the charge on the capacitance upon each detection of a SPAD event within a time period, such that the charge remaining on the capacitance at the end of the time period corresponds to the number of SPAD events detected within the time period. A time resolved imaging apparatus includes an array of such pixel circuits. A method of counting photon detection includes sensing photons with a SPAD device and discharging a known portion of the charge on a capacitance upon each detection of a SPAD event within a time period.
