Abstract
A distance to a target to be read by image capture over a range of working distances is determined by directing an aiming light spot along an aiming axis to the target, and by capturing a first image of the target containing the aiming light spot, and by capturing a second image of the target without the aiming light spot. Each image is captured in a frame over a field of view having an imaging axis offset from the aiming axis. An image pre-processor compares first image data from the first image with second image data from the second image over a common fractional region of both frames to obtain a position of the aiming light spot in the first image, and determines the distance to the target based on the position of the aiming light spot in the first image.
