Abstract
A solid-state image sensing apparatus which can improve the S/N ratio without enlarging the chip area in both of the mode in which pixel signals are summed and the mode in which pixel signals are not summed is provided. The solid-state image sensing apparatus includes an image sensing regionin which a plurality of unit cellsis laid out two-dimensionally, the first vertical signal line, a row selection circuit, a column selection circuit, a horizontal signal lineand a signal processing unit, having a sampling capacitors which accumulate signals corresponding to amplified signals of the unit cells, which selects the case of summing the signals or the case of not summing the signals, wherein the capacitance of the sampling capacitor which accumulates a signal corresponding to an amplified signal of a unit cell for each row when the sum is performed is smaller than the capacitance required for reading out the signal from said capacitor.
