1. A radiographic imaging apparatus for imaging an inside of a body of a subject by emitting X-rays to the subject from an X-ray irradiation unit including an X-ray tube, the radiographic imaging apparatus comprising:
a control unit configured to control X-ray irradiation by the X-ray irradiation unit; and
an operation unit configured to accept an operation for changing a dose of X-rays to be emitted,
wherein the control unit includes:
a preset setting unit configured to preset the dose of X-rays to be emitted;
a standard state setting unit configured to set the dose of X-rays preset by the preset setting unit as a standard state; and
a dose change unit configured to relatively change the dose of X-rays to be emitted with the standard state as a reference, based on an operation to the operation unit, from the standard state to at least one of a high-dose state in which the dose of X-rays to be emitted is higher than that in the standard state by a predetermined dose and a low-dose state in which the dose of X-rays to be emitted is lower than that in the standard state by the predetermined dose.
