Abstract
Camera field of view visualizers differentially illuminate objects visible within and without a camera lens focal area, and also supporting surfaces located outside of but relative to the focal area wherein objects located thereon are visible within the focal area, relative to different supporting surfaces that are also located outside of the focal area but relative to the focal area wherein objects located thereon are not visible within the focal area. At an end of an illumination time period an amount or type of illumination that is visible within image information acquired from objects illuminated thereby within the focal area is reduced or revised for an image data acquisition time period so that it is not visible within image information acquired by an image data receiving means, and image information is captured via the image data receiving means from objects that are located within the focal area.
