    摘要: In order to realize a photoelectric conversion apparatus capable of easily switching a mode requiring a wide dynamic range in obtaining a motion image and a mode requiring a reduction in noise in obtaining a still image, a mode switching means is used, when a refresh operation is performed for each photoelectric conversion element, to switch between a mode of setting the potential of one electrode of the photoelectric conversion element to be higher than the potential of the other electrode, and a mode of setting the potential of one electrode of the photoelectric conversion element to be lower than the potential of the other electrode, thereby arbitrarily changing the refresh voltage. With this operation, desired photoelectric conversion signals for a motion image and a still image can be obtained.

    摘要: A radiation image pickup apparatus or the like which realizes improvement of noise resistance characteristics when adding pixel signals is provided. For this purpose, the radiation image pickup apparatus has a switching unit which is arranged between a signal wiring and an amplifier and can switch electrical connection among a plurality of signal wirings and electrical connection between a predetermined one of the plurality of signal wirings and the amplifier corresponding thereto. In accordance with mode setting, the switching unit switches a first state where the plurality of signal wirings are electrically connected and the predetermined signal wiring and the corresponding amplifier are electrically disconnected and a second state where the plurality of signal wirings are electrically disconnected and the predetermined signal wiring and the corresponding amplifier are electrically connected.
