PHOTOELECTRIC CONVERSION APPARATUS AND SYSTEM HAVING PHOTODIODES TO PERFORM AVALANCHE MULTIPLICATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 18302299 titled 'PHOTOELECTRIC CONVERSION APPARATUS AND SYSTEM HAVING PHOTODIODES TO PERFORM AVALANCHE MULTIPLICATION

Simplified Explanation

The patent application describes a photoelectric conversion apparatus that includes two pixels, each with a photodiode, and a signal processing circuit with a control circuit and a counter.

  • The control circuit is connected to the photodiode and a circuit that generates a pulse signal.
  • The control circuit can switch between a standby state and a recharge state based on the pulse signal.
  • The counter keeps track of the number of periods in which avalanche multiplication occurs in the standby state.
  • The control circuit receives a third pulse for the second pixel while waiting for the second pulse for the first pixel.


Original Abstract Submitted

A photoelectric conversion apparatus includes a first pixel and a second pixel, each of which includes a photodiode, and a signal processing circuit including a control circuit and a counter. The control circuit is connected to the photodiode and a circuit configured to generate a pulse signal, and performs control, based on the pulse signal, so as to be in a standby state or a recharge state. The counter counts the number of periods in which avalanche multiplication has occurred in the standby state. A third pulse of the pulse signal for the second pixel is input to the control circuit in a period from when a first pulse of the pulse signal for the first pixel is input to the control circuit to when a second pulse of the pulse signal for the first pixel subsequent to the first pulse is input to the control circuit.
