Radiation imaging apparatus that determines timing of sampling and holding

A control apparatus, comprising:

• a controller configured to determine, during fluoroscopic imaging, timings of a plurality of sampling and holding operations in each of a plurality of pixels configured to detect radiation, in accordance with a radiation generation condition related to a radiation generating apparatus, the radiation generation condition being obtained during the fluoroscopic imaging, wherein
• the timings of the plurality of sampling and holding operations include a timing of sampling and holding a signal corresponding to radiation having a first energy, and a timing of sampling and holding a signal corresponding to radiation having a second energy different from the first energy.
