Zusammenfassung:An image sensor includes: a pixel array including pixels and reference pixels; an analog sensing circuit configured to sense signals from the pixels and the reference pixels; and a digital logic circuit configured to receive the sensed signals from the analog sensing circuit and configured to compensate signals corresponding to the pixels from among the sensed signals by using signals corresponding to the reference pixels from among the sensed signals, wherein each of the reference pixels is at least partially surround by the pixels.
