Claim 9:
10. A method of determining a tissue type, comprising:
emitting light having a first emission profile with a light source including one or more light emitters;
receiving the light reflected back from tissue in a body with a camera;
outputting image data from the camera to a controller;
comparing the image data to reflectance data in a database using the controller coupled to the camera and the database;
determining a tissue type in the image data in response to comparing the image data to the reflectance data, wherein determining the tissue type includes calculating a first identification probability that the image data includes the tissue type using the image data and the reflectance data;
changing the light emitted from the light source from the first emission profile to a second emission profile based upon a probability threshold of tissue identification;
combinatorially searching through multiple different emission profiles, including the first and second emission profiles, to select one of the multiple different emission profiles that provides a highest identification probability; and
using the selected one of the multiple different emission profiles to identify the tissue type.
