IMAGING SYSTEM, MOVABLE APPARATUS, AND STORAGE MEDIUM

An imaging system includes an imaging unit and an optical system configured to form a low-resolution area at the center of a light receiving surface of the imaging unit and form a high-resolution area in the periphery of the light receiving surface. The optical system is disposed in an upper part of a cabin of a movable apparatus such that an optical axis of the optical system faces downward with respect to a horizontal plane in a state in which the movable apparatus has a horizontal posture. When a focal distance of the optical system is defined as f, a half viewing angle is defined as θ, an image height on an image plane is defined as y, projection characteristics indicating a relationship between the image height y and the half viewing angle θ are defined as y(θ), and a maximum half viewing angle of the optical system is defined as θmax, the optical system is configured to satisfy 0.1
