Abstract
An improved method and apparatus for machine reading of license plate numbers on license plates uses separate illumination sources to (1) identify and locate the license plate image within a field of view, and (2) to read the license plate number from the license plate image. The use of separate sources allows the use of preferred equipment and reduces power consumption of the system.
