IMAGE CAPTURE BASED ON SCANNING RESOLUTION SETTING IN IMAGING READER
First Claim
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.

Abstract
An arrangement for, and a method of, electro-optically reading a target by image capture, employ an aiming assembly for projecting an aiming light pattern on the target that is located within a range of working distances relative to a 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.

11. A method of electro-optically reading a target by image capture, comprising the steps of:
-
projecting an aiming light pattern on the target that is located within a range of working distances relative to a housing; capturing an image of the target and of the aiming light pattern over a field of view; determining a distance of the target relative to the housing based on a position of the aiming light pattern in the captured image; determining a scanning resolution based on the determined distance; comparing the determined scanning resolution with a scanning resolution setting; and processing the captured image based on the comparison. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
