Abstract:
1. A photoelectric conversion apparatus comprising: a plurality of photoelectric conversion elements; a plurality of amplifying means for respectively amplifying signals from the plurality of photoelectric conversion elements; a plurality of reset means for respectively resetting the plurality of photoelectric conversion elements; a plurality of signal holding means for respectively holding output signals from the plurality of amplifying means through switch means; control signal supplying means for supplying a control signal to the switch means through a control line; and differential means for differentiating between an output signal at a reset of a photoelectric conversion element and an output signal based on a photo-carrier generated in the photoelectric conversion element, wherein, in holding both of the output signals by a corresponding signal holding means, an RC time constant formed by the control signal supplying means and the control line is set larger than an RC time constant formed by the corresponding signal holding means and a resistance component between a corresponding amplifying means.
