Abstract: Certain exemplary embodiments can provide a method comprising, responsive to a determination that a machine-readable two-dimensional code has been identified in a first image, said first image comprising a first plurality of pixels defining said machine-readable two-dimensional code and second plurality of pixels defining a non-code zone, automatically causing a saving or displaying of a second image that comprises said machine-readable two-dimensional code or a representation of said machine-readable two-dimensional code and that excludes said non-code zone.

Abstract: A system comprising: a pistol grip barcode reader (1100) adapted to obtain an image of a two dimensional direct part marking barcode, said barcode reader comprising a camera (1400), said camera defining a camera axis, said barcode reader comprising an on-axis lighting module (1500) that comprises first set of light emitting diodes (LEDs) having a first emitted color, said on-axis lighting module adapted to direct light on an on-axis lighting direction that is approximately collinear with said camera axis, said barcode reader comprising an adjustable off-axis lighting module (1700) that is substantially mirror-less, filter-less, and lens-less, said off-axis lighting module comprising a second set of LEDs having a second emitted color, said off-axis lighting module adapted to direct light in an off-axis lighting direction that intersects said camera axis at an adjustable angle, said adjustable angle less than approximately fifty five degrees, said barcode reader adapted to obtain a decodable image at a distance between approximately one inch and approximately four inches from said two dimensional direct part marking barcode.
