ABSTRACT:
A photoelectric conversion apparatus has a plurallity of photoelectric conversion elements each providing an output signal to a storage capacitor. A matrix wiring unit is arranged opposite the photoelectric conversion elements so as not to cross the signal lines extending from the capacitors. The matrix wiring unit matrix transfers the signals from the capacitors. A switch array unit includes a first switch unit for sequentially transferring the matrix transferred signals, and a first readout device for reading out, as a voltage signal, the signals transferred by the first switch section. The switch array also includes a second switch unit arranged in correspondence with the first switch unit and operated synchronously therewith. The second switch unit receives signals corresponding to noise. A second readout device reads out, as a voltage signal, the output from the second switch unit. A differential amplifier is included for receiving the outputs from the first and second readout devices and outputs a signal corresponding to a difference therebetween.
