A radiation imaging apparatus comprising a first memory storing first gain correction data corresponding to imaging modes, a second memory having a higher read speed than the first memory, and a controller being able to perform imaging in the imaging modes is provided. The controller stores second gain correction data based on the first gain correction data in the second memory after startup, and when an imaging request is issued from startup to storage of all the second gain correction data into the second memory and requested gain correction data which corresponds to a requested imaging mode has been stored in the second memory, performs acquisition of radiation image data and offset correction data in the requested imaging mode and correction for the radiation image data by using the offset correction data and the requested gain correction data stored in the second memory.
