Abstract
An image processing device includes a vision sensor and a processor. The vision sensor generates a plurality of events in which an intensity of light changes and generates a plurality of timestamps depending on times when the events occur. In addition, the processor may regenerate a timestamp of a pixel where an abnormal event occurs, based on temporal correlation of the events.
Claims17
An apparatus comprising:
- a processor configured to,
- receive information on a plurality of events through at least one pixel of a plurality of pixels of a vision sensor, the information including a plurality of timestamps associated with times when the plurality of the events occur and polarity information on the plurality of the events, the plurality of pixels including a target pixel and adjacent pixels around the target pixel;
- monitor the timestamps between an event related to the target pixel and events related to the adjacent pixels;
- determine a temporal correlation based on the timestamps;
- and
- regenerate a timestamp of the event of the target pixel.
