A radiation imaging apparatus is provided. The apparatus comprises a scintillator, a sensor panel in which each including a light detector, and a processing unit. The processing unit generates signals in accordance with the light detected by the light detectors, determines whether signals generated in the same period by a pixel group, which includes one pixel of interest and at least one pixel near the pixel of interest out of the pixels, have a specific distribution, obtains a count of the number of times the pixel of interest is determined to have the specific distribution, and obtains, based on a value obtained by converting the count in accordance with a first and a second coefficient, an incident amount of a first and a second energy band out of radiation irradiating the pixel of interest, respectively. |
