Method of and system for reading visible and/or invisible code symbols in a user-transparent manner using visible/invisible illumination source switching during data capture and processing operations

摘要

A digital imaging based symbol reading system has the capacity to automatically read both visible and invisible symbols in the same application environment. Typically, the system reads the symbols in a user-transparent manner. The system may employ visible/invisible illumination switching during operation. The system may include LED illumination sources. A method for reading both visible and invisible symbols using a single device is also disclosed.
