1. A method for detecting objects in the dark, the method comprising:
- a) capturing, by a vehicle camera, a first image when a vehicle lighting is switched off;
b) capturing, by the vehicle camera, a second image when the vehicle lighting is switched on;
c) determining, by a vehicle processor, movement of the vehicle between capturing the first image and capturing the second image;
d) predicting, by the vehicle processor, a position of an object in the second image based on a position of the object in the first image and the movement of the vehicle;
e) generating, by the vehicle processor, a differential image of the second and first images based on the predicted position of the object in the second image; and
f) distinguishing, by the vehicle processor, between lighting devices and reflective objects based on the differential image.

10. A device for detecting objects in the dark using a vehicle camera and a vehicle lighting control unit comprising:
-
a vehicle camera, configured for; a) capturing a first image when a vehicle lighting is switched off; b) capturing a second image when the vehicle lighting is switched on; c) determining movement of the vehicle between capturing the first image and capturing the second image; d) predicting a position of an object in the second image based on a position of the object in the first image and the movement of the vehicle; and an image processor, configured for; a) generating a differential image of the second and first images based on the predicted position of the object in the second image; and b) distinguishing between lighting devices and reflective objects based on the differential image.
