  • Auto-focusing method for an automatic data collection device, such as an image acquisition device
    Patent number: 8328099
    Abstract: An automatic data collection device includes an automatic focusing feature. The automatic focusing feature is based on a type of triangulation technique, which determines an optimum position of an imaging lens in order to obtain an optimally focused image. The position of the imaging lens may be adjusted until the imaging lens is at the optimum position. A pair of aiming beams is separated by a distance. The optimum position of the imaging lens (and/or the amount of displacement of the imaging lens that is needed to reach the optimum position) can be determined based on a relation that involves the distance between the two aiming beams, a focal length of the imaging lens, and a distance between “spots” that are respectively generated on an image plane (such as on an image sensor) by the pair of aiming beams.
