ABSTRACT:
There is provided a solid-state image sensing device including a pixel section in which cells are arrayed, each cell including a photoelectric conversion unit, a reading circuit reading out, to a detection unit, signal charges obtained by the photoelectric conversion unit, an amplifying circuit amplifying and outputting a voltage corresponding to the signal charges, and a reset circuit resetting the signal charges, an exposure time control circuit controlling an exposure time and controlling the exposure time to be equal for all cells, an A/D conversion circuit A/D-converting a signal output from the pixel section by changing a resolution of a signal level, line memories storing an A/D-converted signal, and a signal processing circuit processing output signals from the line memories to have a linear gradient with respect to an optical input signal amount by controlling an amplification factor in accordance with a resolution of a pixel output signal after A/D-conversion.
