Abstract
Generally discussed herein are techniques, software, apparatuses, and systems configured for variable depth of field scanners. In one or more embodiments, a method can include exposing a light sensor of a barcode scanner for a specified time, altering a focal point of a variable focus element situated in the light path of the light sensor from a first focal point to a second focal point in the specified time, and processing an image of a barcode produced by the light sensor to deblur the image.
