Abstract
Signal processing method for histogram generation, and corresponding device and use. The method generates the histogram from a plurality of event detectors that generate event signals as a response to external events, and are connected to a current injection module which is connected to a plurality of capacitors, wherein each histogram bin is univocally assigned to a capacitor. The method includes: during an event time interval corresponding to a bin, the event detectors generate event signals as a response to external events; the current injection module detects said event signals and, for each event signal, generates a corresponding current signal, which is injected in a capacitor assigned to said bin, and stored therein; repeating steps for each successive bin of said histogram; and reading the charge accumulated in each of said capacitors.
