1. An imaging apparatus comprising:
an imaging optical system configured to form an optical image of a face of a subject in a vehicle;
an image sensor configured to capture the formed optical image and generate a captured image; and
an image processor configured to determine a state of the subject based on the captured image,
wherein the imaging apparatus satisfies the expression
F≥0.0003 f2/p,
where F is an F value of the imaging optical system, f is a focal length of the imaging optical system, and p is a pixel pitch of the image sensor.
