Abstract:
A method for adjusting an object distance for focusing upon a face of an item, including a data carrying graphical that is placed within a field-of-view of a fixed focal length imaging device. The method employs using parallax focusing techniques to produce a laser spot indicator, and further calls for providing a fixed on-screen focusing target to indicate a location to which the laser spot indicator must be moved and positioned before in-focus imaging activities can be realized. This abstract is provided to comply with rules requiring abstracts, and is submitted with the intention that it will not be used to interpret or limit the scope and meaning of the claims.
