ABSTRACT:
Embodiments described herein may operate to illuminate an image sensor array (ISA) used in, for example, a digital imager alternately using a first illuminator and a second illuminator laterally offset from the first illuminator with respect to a face of the ISA. A reduced illuminance level consistent with an existence of an occlusion may be sensed at an apparent occluded location on the ISA while the occlusion is illuminated with the first illuminator. If an illuminance level consistent with an existence of the occlusion is also sensed at the apparent occluded location while the occlusion is illuminated using the second illuminator, the occlusion may be identified as being located on the ISA. Otherwise, the occlusion may be identified as being located at a position anterior to the ISA, perhaps on a surface of a cover glass associated with the ISA.
