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.
