Abstract: An image sensor includes a CIS (CMOS image sensor) pixel, a DVS (dynamic vision sensor) pixel, and an image signal processor. The CIS pixel includes a photoelectric conversion device generating charges corresponding to an incident light and a readout circuit generating an output voltage corresponding to the generated charges. The DVS pixel detects a change in an intensity of the incident light based on the generated charges to output an event signal and does not include a separate photoelectric conversion device. The image signal processor allows the photoelectric conversion device to be connected to the readout circuit or the DVS pixel.

Abstract: A method of correcting dynamic vision sensor (DVS) events is described. The method generates event data including events representing motion information of an object included in an image. Additionally, the method generates image data capturing an image and generates edge data representing edge information of the image based on the image data. The method also generates omitted events of the event data based on the edge data. Accuracy of the event data and performance of machine vision devices and systems operating based on the event data are enhanced by supplementing the omitted events of the event data provided from the DVS, using the edge information.
