1. A hand held data collection terminal comprising:

  • a two dimensional image sensor comprising a plurality of pixels formed in a plurality of rows and columns of pixels;

    an imaging lens assembly comprising a deformable lens element for focusing an image onto said two dimensional image sensor, said imaging lens being adapted so that said deformable lens element can be deformed with use of a force imparting structural member, said imaging lens assembly being adapted so that force can be applied to an external surface of said deformable lens element to vary an optical property of said deformable lens element, said imaging lens setting having a first lens setting at which said deformable lens element is in a first state and a second lens setting at which said deformable lens element is in a second state; and

    a trigger for activating a trigger signal, said data collection terminal being adapted so that said trigger signal can be maintained in an active state by maintaining said trigger in a depressed position;

    wherein said data collection terminal is adapted so that responsively to said trigger signal being maintained in said active state, said data collection terminal captures in succession a plurality of frames of image data, each of said plurality of frames of image data representing light incident on said image sensor at an instant in time, wherein said data collection terminal is adapted so that a lens setting of said imaging lens assembly is varied while said trigger signal is maintained in said active state in such manner that said lens assembly is at said first setting for an exposure period corresponding to at least one of said plurality of frames of image data, and said lens assembly is at said second lens setting for an exposure period corresponding to at least one of said plurality of frames of image data.
