22. A method for sensing an eyeball, the method comprising:
by using an imaging element having an event-driven function:
generating a Purkinje detection mode, generating a pupil detection mode, and generating an event-driven mode; and
transitioning to the Purkinje detection mode, transitioning to the pupil detection mode, and transitioning to the event-driven mode; and
changing to three light emission intensity states using a light emitting device.
