ALEXANDRIA, Va., Jan. 20 -- United States Patent no. 12,532,088, issued on Jan. 20, was assigned to Commissariat a l'Energie Atomique et aux Energies Alternatives (Paris).

"Event-driven high dynamic range image sensor and method" was invented by Josep Segura Puchades (Grenoble, France).

According to the abstract* released by the U.S. Patent & Trademark Office: "A pixel circuit of an image sensor comprises a pinned photodiode (PD) coupled to a sense node (SN); a comparator (104) configured: to compare, during a first read phase, a first sense node voltage (Vpix) at the sense node (SN) with a first voltage ramp (V_RAMP) and to generate an event signal (EVENT) if the voltage of the first voltage ramp (V_RAMP) crosses the first sense node vol...
