1. An imaging control apparatus comprising:
at least one of (a) one or more processors connected to one or more memories storing a program including instructions executed by the one or more processors and (b) circuitry configured to function as:
performing energy subtraction processing using a plurality of pieces of information related to different radiation energies to generate an energy subtraction image, the plurality of pieces of information being obtained by sampling at least twice in a period which is within a one shot in which a subject is irradiated with radiation whose energy changes during the one shot and which is between consecutive resets in a two-dimensional detector; and
generating a difference image using a plurality of energy subtraction images generated by the energy subtraction processing.
