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
A dynamic vision sensor comprising:
- an upper semiconductor chip including a pixel array, the upper semiconductor chip configured to detect a plurality of events through at least one pixel of a plurality of pixels of the dynamic vision sensor;
- a lower semiconductor chip on the upper semiconductor chip including a column address event representation circuit (AER), a row AER, a packetizer, and an input/output circuit;
- and
- the row AER is configured to receive polarity information from the pixel array, and generate timestamps associated with times when the plurality of the events occur.
