Abstract
Photodetection elements and electronic apparatus that shorten a detection cycle of an event signal are disclosed. In one example, a photodetection element includes a light receiving unit that photoelectrically converts incident light to generate an electric signal, and a comparison unit which outputs an event signal when an amount of change in the electric signal exceeds or falls below a threshold A first recording unit is connected to an output terminal of the comparison unit, records the event signal, and outputs the event signal. A second recording unit is connected to the first recording unit, records the event signal from the first recording unit, and outputs the event signal.

A photodetection element comprising:
- a light receiving unit that photoelectrically converts incident light to generate an electric signal;
- a comparison unit which outputs an event signal when an amount of change in the electric signal exceeds or falls below a threshold;
- a first recording unit that is connected to an output terminal of the comparison unit, records the event signal, and outputs the event signal;
- and
- a second recording unit that is connected to the first recording unit, records the event signal from the first recording unit, and outputs the event signal.
A photodetection element comprising:
- a light receiving unit that photoelectrically converts incident light to generate an electric signal;
- a comparison unit that compares an amount of change in the electrical signal generated by the light receiving unit with a threshold and outputs an event signal;
- and
- first and second recording units that are connected in parallel to an output terminal of the comparison unit, wherein
- when one of the first and second recording units records the event signal, another of the first and second recording units outputs the event signal.
