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.
