Patent ID: 7587078

Claim:
An apparatus comprising: a first light source that can provide a first spectral region to a sample; a first detector that can detect first images of portions of the sample when illuminated by the first spectral region; a first computer that can select a subset of the first images based a first set of criteria; a second light source, which may be the first light source or a different light source, that can provide a second spectral region different from the first spectral region; a second detector, which may be the first detector or a different detector, that can detect a second image of the images in the selected subset when illuminated by the second spectral region; and a second computer, which may be the first computer or a different computer, that can produce a combined image comprising the second image and the first image for the selected subset and can select a further subset of the combined images based on a second set of criteria which may be the first set of criteria or a different set.
