ABSTRACT:
The present invention provides a novel hand-held data capture system with interchangeable modules including an autofocusing data file image reader. Several exemplary modules having various features are described. For example the invention teaches an apparatus and method for providing an interchangeable RF module, an interchangeable reflected image reader, two exemplary interchangeable non-scanning laser illuminated bar code reader/RF modules, and three exemplary interchangeable long range CCD reader/RF modules. Also disclosed for the described modular system are noise filtering means, a solid state laser illumination system, signal processing means, and filter, exposure control, and depth of field control means. An exemplary autofocusing system adjusts the lens to a position where the intensity change with respect to time or with respect to position is maximized. A novel focusing system employs several signal processing algorithms, including a method whereby the maximum slope of the intensity of the image signal with respect to time or with respect to position is determined. Mathematical operations may be performed by a high performance digital signal coprocessor.
