Abstract
A radiation imaging apparatus includes a pixel unit including a plurality of pixels and configured to generate image data according to received irradiation of radiation from a radiation generation apparatus, and a control unit configured to acquire irradiation information regarding a radiation irradiation area or an irradiation position of the pixel unit, calculate brightness information of each of successive pieces of image data provided by the pixel unit based on the image data and the irradiation information, generate irradiation condition information of the radiation generation apparatus based on the brightness information, and transmit the irradiation condition information to the radiation generation apparatus. The control unit recalculates the brightness information when a fluctuation of the brightness information exceeds a threshold value. The control unit does not transmit irradiation condition information based on the recalculated brightness information to the radiation generation apparatus until a predetermined period of time elapses since the recalculation.
