Abstract
A radiation imaging apparatus comprising: a signal generation unit configured to generate a signal value corresponding to charges detected by a radiation detector; an acceleration detection unit configured to detect acceleration applied to the radiation imaging apparatus; a noise measurement unit configured to measure a noise value based on the detected acceleration; a reduction unit configured to reduce the noise value from the signal value; and a radiation irradiation determination unit configured to determine radiation irradiation based on the noise-reduced signal value.
