Abstract
A radiation imaging apparatus executes a correction value determination operation of reading out a signal from a pixel once or more in a state where radiation is not emitted onto the apparatus, and determining a correction value that is based on the signal read out from the pixel, and a radiation dose determination operation of reading out a signal from the pixel while radiation is emitted, and determining a dose of radiation that is being emitted, using a value of the signal read out from the pixel and the correction value. The apparatus executes the correction value determination operation and executes the radiation dose determination operation using the correction value in a case where it is determined that the correction value determination operation is to be executed, and otherwise executes the radiation dose determination operation without executing the correction value determination operation.
