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.
