1. A movable apparatus comprising:
a first imaging device including an optical system that forms an optical image, which has a low resolution region near an optical axis and a high resolution region outside the low resolution region, on a light receiving surface of an imaging element,
wherein the first imaging device is installed at a first installation position where an image is captured in at least one of a horizontal backward direction of one side surface of the movable apparatus, right or left direction in a horizontal direction ahead of a driver's seat of the movable apparatus, and a downward direction ahead of the movable apparatus in the high resolution region of the optical system,
wherein, when the image height of the optical system is y, f is a focal distance of the optical system, and θ is a half angle of view, a projection characteristic y(θ) satisfies the following condition of 0.2<2*f tan(θ max/2)/y(θ max)<0.92.
