Patent Images

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;

    a controller for determining a distance of the target relative to the housing based on a position of the aiming light pattern captured during a ranging frame, 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 image captured during a processing frame that occurs at a different time than the ranging frame;

    wherein the controller is operative for rejecting the captured image when the determined scanning resolution is less than the scanning resolution setting, and for advising a user to change the distance of the target; and

    wherein the controller is operative for accepting the captured image only if the determined scanning resolution is at least equal to the scanning resolution setting.
