Abstract
Lenses used in computer vision systems have many nonideal behaviors that can have a significant effect on vision tasks if not taken into account or compensated for. The authors show how two nonideal lens behaviors, chromatic aberration and focus magnification, can cause significant problems in color image analysis and focus ranging respectively. They show how precise active lens control can be used to reduce these effects significantly
