摘要：
To provide a radiation imaging apparatus capable of restraining the change of image qualities due to the change of sensitivities of an MIS-type photoelectric conversion element and its control method. Therefore, an MIS-type photoelectric conversion element 217 is set to a saturation state before performing radiation imaging. As means for realizing the above mentioned, a light source 601, power supply 603 for making the light source 601 emit light, and switch 605 are provided. The light source 601 can use a light source capable of discharging the light having a wavelength which can be detected by a photoelectric conversion layer 209 at optional timing. For example, it is possible to use a light source in which a plurality of LEDs or cold cathode ray tubes are arranged, a light guide plate is combined with an LED or cold cathode ray tube, or an EL device.
