Abstract
A camera testing apparatus includes a frame assembly, a control unit, and a plurality of first light sources and second light sources coupled to the frame assembly and in communication with the control unit. Each of the first and second light sources is in one of an illuminated first state or a non-illuminated second state, and each of the plurality of first and second light sources is adapted to be within a field of vision of a camera disposed remote from the first and second light sources. The control unit sends a first command to each of the first light sources to change a first operational parameter. The control unit sends a second command to a first one of the second light sources to illuminate at a first brightness and a third command to a second one of the second light sources to illuminate at a second brightness.
