Patent ID: 8654210

Claim:
A method of image capture using an image capture device which includes an imaging assembly having a spectral sensitivity tunable in accordance with a spectral capture mask, the method comprising: a pre-capture step of capturing a sample image of a scene using the imaging assembly tuned by a first spectral capture mask; a construction step of constructing a second spectral capture mask by calculations which use image data of the sample image, wherein the second spectral capture mask is constructed to tune the spectral sensitivity of the imaging assembly so as to adjust respective capture parameters for different objects in the scene to increase differentiation between the different objects in the scene, and wherein the second spectral capture mask is constructed to tune the spectral sensitivity of the imaging assembly so as to permit visual differentiation between objects in the scene formed from different materials but which would otherwise have similar tri-stimulus color values: an application step of applying the second spectral capture mask to the imaging assembly; and a capture step of capturing an image of the scene, wherein the image of the scene is captured with the second spectral capture mask applied to the imaging assembly.
