1. An imaging apparatus configured to communicate with an information processing apparatus that generates an image, based on information about a viewpoint position set in a virtual space, the imaging apparatus comprising:
an image sensor configured to capture an image of a subject formed by an imaging optical system;
a pan and tilt drive configured to rotate an imaging direction of the image sensor in a pan direction or a tilt direction;
at least one processor; and
a memory coupled to the at least one processor, the memory having instructions that, when executed by the processor, performs operations as:
acquiring a position that does not change by rotation of the pan and tilt drive as a reference position, and acquire a position of an entrance pupil of the imaging optical system with respect to the reference position; and
outputting information including the position of the entrance pupil to the information processing apparatus,
wherein the viewpoint position is set based on the position of the entrance pupil,
wherein the position of the entrance pupil with respect to the reference position is recalculated according to change of one of a focus position and a zoom position.
