Claim 3:
4. An endoscope system for capturing a scene, comprising:
a plurality of lighting elements located at a distal end;
a camerahead for capturing a first set of one or more images of the scene; and
software and/or hardware comprising at least one process, wherein the at least one process is configured to:
determine correspondences between a plurality of regions of the first set of one or more images and a first lighting element of the plurality of lighting elements, wherein the at least one process is configured to determine the correspondences for the plurality of regions of the scene by at least:
identify a predetermined pattern;
determine, from a first image of the first set of one or more images, an actual pattern projected onto the scene by the first lighting element using the one or more non-visible wavelengths; and
determine a second correspondences for the first lighting element based on a comparison of the predetermined pattern and the actual pattern;

determine pixel intensities at the plurality of regions;
determine a first drive strength for the first lighting element based on the correspondences and the pixel intensities; and
cause the first drive strength to be applied by the first lighting element.
