1. An event signal processing method comprising:
- receiving an activation signal that indicates sensing of an event from a sensor array in a sleep mode;
determining whether a sensing area corresponding to the activation signal among a plurality of sensing areas of the sensor array is a flickering area; and
switching the sensor array from the sleep mode to an active mode based on a determination that the sensing area corresponding to the activation signal is not the flickering area.

Abstract
An event signal processing method and an event-based sensor performing the event signal processing method are provided. The event signal processing method includes receiving an activation signal to indicate sensing of an event from a sensor array, increasing the cumulative event number of a sensing area corresponding to the activation signal among sensing areas of the sensor array, reducing the cumulative event number of each of the sensing areas based on a parameter; and determining, as a flickering area, a sensing area among the sensing areas, of which the cumulative event number exceeds a threshold.

7. An event-based sensor comprising:
-
a sensor array configured to output an activation signal to indicate sensing of an event; and a signal processor configured to increase a cumulative event number of a sensing area among a plurality of sensing areas in the sensor array that corresponds to the activation signal, to reduce the cumulative event number of each of the plurality of sensing areas based on at least one parameter, and to determine, as a flickering area, at least one sensing area among the plurality of sensing areas of which the cumulative event number exceeds a threshold. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16)

17. An event signal processing method comprising:
-
sensing activation of one or more sensing areas among a plurality of sensing areas of a sensor array; determining whether the activated one or more sensing areas are associated with a meaningful event or a meaningless event; filtering out sensing areas determined to be associated with the meaningless event; and outputting an event signal corresponding to sensing areas determined to be associated with the meaningful event. - View Dependent Claims (18, 19)
