Abstract:
1. An imaging apparatus comprising: a detector including a plurality of conversion elements each having a first electrode, a second electrode, and a semiconductor layer disposed between the first electrode and the second electrode and converting radiation or light into charge, the detector performing an imaging operation of outputting an electrical signal based on the charge; a power supply unit that supplies a first voltage to the conversion elements for enabling the conversion elements to convert the radiation or light into the electric charge in the imaging operation to the conversion elements; and a control unit that controls the detector and the power supply unit, wherein the control unit controls the detector and the power supply unit to perform a first inter-imaging operation in which a second voltage different from the first voltage is supplied to the conversion elements, during a period between, in the imaging operation which is performed a plurality of times, a first imaging operation and a second imaging operation subsequent to the first imaging operation, and a second inter-imaging operation in which a third voltage different from the first voltage and the second voltage is supplied, during the period, subsequently to the first inter-imaging operation, and wherein the absolute value of the difference between the third voltage and the first voltage is smaller than the absolute value of the difference between the second voltage and the first voltage.
