Abstract
An image sensor may include a photodiode configured to convert an optical signal into photogenerated charge, a sensing node adjacent to the photodiode and configured to sense the photogenerated charge, a read-out circuit configured to convert the photogenerated charge into an electrical signal and to output the electrical signal through an output line, and/or at least one capacitor formed between the sensing node and a conversion gain control line. The conversion gain control line corresponding to the at least one capacitor may be selectively connected to a ground line or the output line based on at least one control signal.
