1. An arrangement for electro-optically reading a target by image capture, comprising: a housing; an aiming assembly for projecting an aiming light pattern on the target that is located within a range of working distances relative to the housing; an imaging assembly for capturing an image of the target and of the aiming light pattern over a field of view; and a controller for determining a distance of the target relative to the housing based on a position of the aiming light pattern in the captured image, for determining a scanning resolution based on the determined distance, for comparing the determined scanning resolution with a scanning resolution setting, and for processing the captured image based on the comparison.
