1. An image capturing apparatus comprising an image capturing unit configured to include an optical system that forms a low-resolution region on a central side of a light-receiving surface, and that forms a high-resolution region on a peripheral side of the light-receiving surface,
wherein the image capturing unit is arranged on a vehicle so that an image of a lower side and forward-rearward direction of the vehicle is formed in the high-resolution region of the light-receiving surface of the image capturing unit by the optical system,
wherein when a focal distance of the optical system is f, a half-angle of view is θ, an image height on an image plane is y, a projection characteristic representing the relationship between the image height y and the half-angle θ is y(θ), and θmax is the maximum half-angle of view of the optical system, the image capturing apparatus is configured to satisfy the following equation:
0.2<2×f×tan(θmax/2)/y(θmax)<0.92.
