1. An evaluating apparatus configured to evaluate image stabilizing performance of an imaging unit around an optical axis, the evaluating apparatus comprising:
an object disposed to face the imaging unit, the object having a first feature point at a position different from the optical axis of the imaging unit;
an excitation unit configured to excite the imaging unit;
an evaluating unit configured to evaluate an image of the object captured by the imaging unit that is being excited by the excitation unit, and
a scanner configured to scan the object,
wherein the object has a second feature point at a position different from the first feature point, and
wherein the evaluating unit evaluates, as the image, a single locus image regarding the first feature point and the second feature point captured by the imaging unit that is being excited by the excitation unit.
