ABSTRACT:
A dataform reader which includes a hand-portable sized housing and an image assembly included within the housing. The image assembly includes a lens array or other optical system for obtaining a plurality of images of the dataform when positioned a given distance from the dataform. Each of the plurality of images is obtained relative to a different respective best focus length from the image assembly. The dataform reader further includes processing circuitry within the housing for selecting, from among the plurality of images, an image satisfying a predefined focus criteria. The selected image may then be decoded.
