Abstract
Devices, systems, and methods for providing a hybrid fixed focus during operation of an indicia reader. An example system includes at least one imaging assembly; controller; and one or more processors configured to (a) initiate a ranging operation; (b) determine a range value associated with a distance between the imaging assembly and an object; (c) retrieve a threshold range value from memory; (d) compare the range value to the threshold range value; (e) initiate a hybrid fixed focus operation comprising: (i) energizing an illumination assembly to provide illumination; and (ii) capturing a first set of images at a fixed focus position corresponding to the range value responsive to the range value not exceeding the threshold range value, and the fixed focus position corresponding to the threshold range value responsive to the range value exceeding the threshold value; and (f) terminate the hybrid fixed focus operation based upon a termination signal.
