1. A camera module configured to be mounted on an inside of a windshield of a vehicle and to image an external environment of the vehicle, the camera module comprising:
- a plurality of lens units having optical axes, respectively, wherein the optical axes are shifted from each other, an optical image of the external environment individually enters within angles of view, which are around the optical axes, respectively, the angles of view are different from each other; and
an imaging system to perform imaging individually through the lens units and to generate an outside image of the external environment, whereinunder a definition that a noted set is a set of the lens units in which angles of view overlap with each other, at least two of the lens units, which belong to the noted set, overlap with each other when viewed in a vertical direction of the vehicle,the optical axes of the at least two of the lens units are shifted from each other in both the vertical direction and a width direction of the vehicle.

Abstract
A camera module, which is mounted on an inside of a front windshield of a vehicle and configured to image an external environment of the vehicle, includes multiple lens units on which an optical image of the external environment is incident, individually, and an imaging system to generate an outside image of the external environment by imaging through each of the lens units, individually.
