Abstract
A method includes generating a first illumination with an illumination source, and directing the first illumination to pass through an aperture to generate an illumination pattern for defining an illumination field of view that is configured to indicate a boundary surrounding the imaging field of view of the imaging system. The intensity of the first illumination changes with time. The intensity variation of the illumination pattern is perceivable by a human user. The method also includes detecting light from the barcode with the imaging sensor to create imaging data while the barcode is illuminated by a second illumination, and processing the imaging data to decode an image of the barcode.
