1. A control apparatus comprising:
at least one processor that is configured to:
capture a low-energy image by a radiography apparatus by emitting radiation having first energy to a subject into which a contrast medium has been injected, and then sequentially acquires each of a plurality of high-energy images captured by the radiography apparatus at different timings by emitting radiation having second energy higher than the first energy to the subject into which the contrast medium has been injected,
sequentially derive a body movement amount of the subject from each of the plurality of high-energy images, and
perform, in a case in which the derived body movement amount exceeds a threshold value, control of causing the radiography apparatus to re-capture the low-energy image before a next high-energy image is captured.
