Abstract
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.
