1. A control device comprising:
at least one processor,
wherein the processor is configured to:
acquire a compression plate identifier that identifies a type of a compression member attached to a mammography apparatus and an angle of an arm portion of the mammography apparatus, the mammography apparatus being configured to irradiate a breast compressed by the compression member with radiation to capture a radiographic image;
acquire irradiation field information indicating a size of a range of an irradiation field of the radiation of the mammography apparatus, based on the compression plate identifier and the angle of an arm portion, the irradiation field information comprising information expressing a relationship of the compression plate identifier, the angle of the arm portion and the size of the range of the irradiation field; and
control an image projection unit that projects a projection image onto a projection surface of the compression member such that a range of an irradiation field of the radiation is displayed by the projection image, in a case in which a size of a display image displayed on the projection surface by the projection image is different from the size of the range of the irradiation field indicated by the irradiation field information,
wherein a display image displayed on the projection surface due to the projection of the projection image is an image larger than the range of the irradiation field on the projection surface of the compression member.
