Abstract
Imaging circuits, devices and methods are disclosed. In one example, an imaging circuit includes circuit blocks each including a photoelectric conversion element configured to photoelectrically convert incident light to generate a photocurrent and a current-voltage conversion circuit configured to convert the photocurrent into a voltage signal, a quantizer configured to generate a detection signal of an address event in accordance with a result of comparing the voltage signal supplied from at least one of the plurality of circuit blocks with a threshold, a demultiplexer connected to a subsequent stage of the quantizer, and latch circuits connected to different output terminals of the demultiplexer.
