Near and far imagers image close-in and far-out targets over relatively wider and relatively narrower imaging fields of view, respectively. An aiming assembly directs to a target a visible aiming light pattern having an aiming light spot and a pair of collinear aiming light lines. The aiming light spot is substantially centered between the aiming light lines. A controller determines a distance to the target based on a position of the aiming light spot in the imaging field of view of a default one of the imagers, selects at least one of the imagers based on the determined distance, and enables both the close-in and the far-out targets to be positioned substantially entirely within the respective imaging field of view of the selected imager.

Imaging module and reader for, and method of, reading targets by image capture over a range of working distances with multi-functional aiming light pattern

An imaging scanner includes an aiming light source configured to emit visible light through both the shape defining element and the aiming lens arrangement to generate an aiming pattern on a target object. The shape of the aiming pattern changes with the distance between the target object and the imaging scanner. For determining the distance, the shape of the aiming pattern in a pixel data is compared with the expected shape of aiming patterns at multiple distances.
