Abstract:
A method for modifying a brightness level of an automobile vehicle backup light includes: receiving electronic signals in a brightness evaluator and light controller defining at least one image captured within a field-of-view (FOV) of an automobile vehicle camera; dividing the at least one image into multiple independent zones; evaluating an environmental brightness level of individual ones of the multiple independent zones; comparing a brightness level of at least one backup light of the automobile vehicle to the environmental brightness level; and sending a control signal to the at least one backup light to modify the brightness level of the least one backup light.
