Data capture terminal with automatic focusing over a limited range of working distances
Abstract:
A data capture terminal for, and a method of, automatically capturing data from targets located within a range of working distances from the terminal, employ a controller for automatically controlling a set of focal parameters of an imaging assembly, for storing one of the focal parameters of the imaging assembly upon a successful data capture from a first target, and for automatically selecting a subset of the focal parameters determined from the stored focal parameter to capture data from a second target. The subset is smaller than the set of the focal parameters and corresponds to a restricted zone within the range of working distances to enhance data capture performance of the terminal.
