IMAGE PICKUP SYSTEM

An image pickup system includes an image pickup apparatus mounted on a movable body. The image pickup apparatus includes an optical system and an image sensor configured to image an object via the optical system. An imaging surface of the image sensor has a first area for imaging an object included in a first angle of view, and a second area for imaging an object included in a second angle of view larger than the first angle of view. The number of pixels per unit angle of view in the second area is larger than the number of pixels per unit angle of view in the first area. In a case where the movable body moves in a horizontal direction, the image pickup apparatus is installed so that an optical axis of the optical system is nonparallel to the horizontal direction. Predetermined inequalities are satisfied.
