Abstract:
1. An apparatus comprising: an image sensor array having a plurality of pixels, a memory for storing image data, wherein the apparatus is adapted for processing the image data for attempting to decode decodable indicia represented in the image data, a variable lens assembly for focusing an image of a target onto the image sensor array, the variable lens assembly including a lens element having a first light transmissive substrate and a second light transmissive substrate, the first light transmissive substrate including a first electrode, the second light transmissive substrate including a second electrode, the lens element further having liquid crystal material disposed between the first substrate and the second substrate, the apparatus further being operative to expose during a first exposure period a first frame of image data with the lens assembly defining a plane of optimum focus distance “a” from the apparatus and during a second exposure period a second frame of image data with the lens assembly defining a plane of optimum focus distance “b” from the apparatus, and wherein the apparatus is further configured so that the apparatus is operative to subject each of the first and second frames of image data to a decode attempt for decoding of a decodable indicia; and wherein the lens assembly is at a maximally far focus lens settings during the first exposure period so that distance “a” is a fixed distance, and wherein the lens assembly is at a minimally near focus lens setting during the second exposure period so that distance “b” is a fixed distance.
