1. An imaging system that calibrates a parameter of an imaging apparatus disposed in a predetermined position, the imaging system comprising:
a movement controller that causes a movable object that includes a marker for use in calibration to move into an imaging area of the imaging apparatus;
an imaging controller that causes the imaging apparatus to image the marker; and
a calibrator that calibrates an internal parameter of the imaging apparatus, using an image that includes the marker, the image being captured by the imaging apparatus imaging the marker, wherein
the movable object includes a display apparatus that displays the marker, and
the display apparatus is configured to change the shape of the marker displayed so that the shape of the marker included in an image captured by the imaging apparatus is rectangular or square.
