Abstract
A hand-held bar code reader includes a laser scanning module and a two dimensional image sensor and processing for reading a bar code. The laser scanner assists the 2D image processing by providing information on location, type, range, reflectivity, and presence of bar code for 2D reading. Additionally, the 2D imaging reading operation is improved by using the laser scan as a spotter beam for aiming.
