ABSTRACT:
In one embodiment, an apparatus comprises a camera and a group of light emitting diodes configured and arranged to illuminate an object imaged by the camera. The group of LEDs comprises at least one first LED of a first type that emits light with a first spectrum profile and at least one second LED of a second type that emits light with a second spectrum profile that is substantially different than the first spectrum profile. The apparatus may further comprise an adjustment mechanism for adjusting of the relative amounts of illumination energy generated by the at least one first LED and the at least one second LED during each of a plurality of scan cycles of the camera.
