ABSTRACT:
To prevent such a situation that a signal from a pixel in a dark state is output at a level shifted from an originally set level to deteriorate an image quality, and to improve the image quality. A photoelectric conversion apparatus according to the present invention includes: a plurality of photoelectric conversion elements; a plurality of amplifying units for amplifying a signal in accordance with a photo-carrier generated in the photoelectric conversion elements; a plurality of signal holding units for holding output signals from the amplifying units through a plurality of switch units; and a control signal supplying unit for supplying a control signal to the switch units through a control line, in which the control line is sequentially connected to the plurality of switch units and has both ends connected to the control signal supplying units, or a change rate with time of an amplitude of a signal held by the signal holding units is set lower than a change rate with time of am amplitude of the control signal at the time of turning off the switch units.
