An area of interest is scanned to produce pixels of the scanned area. The pixels are divided into a plurality of blocks. For each block, an orientation of a spanning line or a lack of orientation is determined. Contiguous ones of the blocks are clustered, when their orientation is within a certain tolerance level. Each cluster has a length and a width. The length is longer than the width. If the orientation of a cluster's block is perpendicular to the length of that cluster, that cluster is selected as a bar code candidate.

Detecting bar code candidates

A system for high speed acquisition and decoding of a barcode symbol locates potential barcode candidates within a scanned image and filters the candidates to eliminate invalid data. The system permits computational resources to be focused on decoding information most likely to be an actual barcode symbol. Once a potential barcode candidate has been located, the barcode symbol is processed to determine the barcode orientation and symbology. Each element of the barcode symbol is then located, even if all elements are not visible in the original image, and the barcode symbol is decoded in accordance with the specific symbology.

A hand-held scanning device employs apparatus for varying the depth of field of the scanning device. The scanning device comprises a gun-shaped housing for comfortably fitting within the hand of an operator. The scanning device is actuated by a finger-activated trigger, which moves a CCD sensor on an image plane as the trigger is pulled. In this manner, focusing for large depth of field applications is achieved.
