Abstract: An image sensor includes a substrate the substrate including a plurality of unit pixels arranged in a direction parallel to a first direction; a first and second photodiode inside of the substrate in each of the plurality of unit pixels and separated from each other in a second direction, perpendicular to the first direction; and a device isolation film between the plurality of unit pixels. A pair of pixels side-by-side in a third direction, perpendicular to the first and second direction, among the plurality of unit pixels, share a microlens, and at least one of the plurality of unit pixels includes a light shielding film on the substrate. Accordingly, in the image sensor, while maintaining the existing photodiode forming process, the autofocusing function in a vertical direction may be supplemented, and further, performance of the image sensor may be improved.

Abstract: 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.
