Claim One:
1. A method for adaptive spectral image capture using an image capture device which includes an imaging assembly having a spectral response which is tunable in accordance with a capture parameter, the method comprising: applying a default capture parameter to the imaging assembly, wherein the default capture parameter has high spectral dimensionality; capturing a sample image of a scene; analyzing the sample image to identify transition zones between multiple different regions in the scene, wherein each of such multiple different regions shares similar spectral content that is dissimilar from spectral content in adjacent ones of the multiple different regions; adjusting a spectral sensitivity of the imaging assembly for each region of the multiple different regions by determining a capture parameter to be applied to the imaging assembly; applying the capture parameter to the imaging assembly; and capturing and storing a spectral image of the scene, wherein identification of each transition zone comprises: applying a high-pass filter to the sample image to derive a preliminary estimate of the transition zone; selecting a filter mode from among a predetermined collection of filter modes, wherein the selected filter mode is selected based on color characteristics of the preliminary estimate of the transition zone; and applying the selected filter mode to the sample image.
