Patent ID: 8827161

Claim:
An imaging device comprising: a first illumination means having a first light source, wherein the first light source is arranged to illuminate a field of view at a first depth-of-field from the device; a second illumination means having a second light source and a third light source, wherein the second and third light sources are arranged to illuminate a field of view at a second and further depth-of-field from said device; a masking portion having a first opening and a second opening that respectively surrounds the second and third light sources: (i) wherein the second light source is offset within the first opening relative to a center of a first lens arranged in front of the first opening, (ii) wherein the third light source is offset within the second opening relative to a center of a second lens arranged in front of the second opening, (iii) wherein the center of the first lens is independent of the center of the second lens, (iv) wherein the second light source, as a result of its offset, is positioned differently within the first opening when compared to the position of the third light source within the second opening, (v) wherein the second light source is a Light Emitting Diode (LED) that is aligned with one side of the first lens arranged in front of the first opening, and (vi) wherein the first lens is aligned with an outer side of the masking portion, the outer side of the masking portion being dimensioned and arranged to partially shield illumination that is emitted by the second light source; and an imaging array to capture light reflected from a target object.
