description A solid-state image sensing device includes: a photoelectric conversion unit that converts light into electrical signals for respective pixels and outputs the electrical signals; a signal separation unit that separates an offset signal, which is generated due to dark current, from each of the electrical signals outputted by the photoelectric conversion unit and outputs image signals which are electrical signals converted from light for the respective pixels; and a signal adding unit that adds the image signals, which is outputted from the signal separation unit, for each group of a plurality of pixels.
