Camera field of view visualizer

摘要

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.

主权项

1. A computer-implemented method for a camera field of view visualizer, the method comprising executing on a processor the steps of:
projecting for an illumination time period a first illumination light onto a portion of a first supporting surface that is located outside of and directly beneath a generally elliptical focal area of a camera lens that spreads outward with increasing distance from the camera lens, wherein the portion is defined as an area of the first supporting surface that is not visible within the focal area relative to the camera lens that is bounded by left and right outer boundary lines projected downward from outer boundaries of the generally elliptical focal area, and wherein a first object located upon the first supporting surface portion projects upward into and is visible within the focal area relative to the camera lens; at an end of the illumination time period, in response to a determination that the first illumination light is visible within image information that is acquired from the first object illuminated thereby within the focal area, revising an amount or type of the projected first illumination light for an image data acquisition time period, wherein the revised amount or type of the projected first illumination light is not visible within the image information acquired by the image data receiving means from the first object illuminated thereby; and capturing via the image data receiving means, during the acquisition period of time, photographic image information from the first object that is located on the first supporting surface portion and thereby within the focal area, wherein the image data receiving means does not capture photographic image information from the first supporting supporting surface portion during the acquisition period of time.
