Abstract
A detection circuit configured to detect whether an event has occurred based on whether an amount of change in an amount of incident light exceeds a predetermined threshold and a counting circuit configured to count the number of incident photons within a predetermined exposure period are included. A mode control circuit controls a first switch configured to switch between a first mode in which a photodiode and the detection circuit are connected to each other and a second mode in which the photodiode and the counting circuit are connected to each other.
Claims17
An apparatus comprising:
- a photodiode including a first terminal and a second terminal;
- a detection circuit configured to detect whether an event has occurred based on whether an amount of change in an amount of incident light exceeds a predetermined threshold;
- a counting circuit configured to count the number of incident photons within a predetermined exposure period;
- a first switch configured to switch between a first mode in which the photodiode and the detection circuit are connected to each other and a second mode in which the photodiode and the counting circuit are connected to each other;
- a second switch configured to switch a potential of the first terminal of the photodiode;
- and
- a mode control circuit configured to control the first switch,
- wherein the second switch switches between the first mode and the second mode.
