Patent ID: 8665355

Claim:
A method for capturing an image of a scene, wherein the image of the scene is captured by an image capture device that includes an imaging assembly which has a spectral response which is tunable in accordance with a capture parameter, wherein the imaging assembly comprises an image sensor which has a tunable spectral response, the method comprising: applying a first capture parameter to the image sensor of the imaging assembly, and capturing a preview image of the scene using the imaging assembly whose spectral response is tuned in accordance with the first capture parameter; displaying a user interface by which first and second regions of the preview image are designated, and by which a target range is set for contrast between the first and second regions, wherein displaying a user interface comprises: displaying the user interface by which a user is permitted to designate a single region in the preview image or two regions in the preview image; responsive to the designation of the single region in the preview image, segmenting the single region into the first region and the second region by discrimination between high and low illumination regions in the single region; and responsive to the designation of two regions, designating the two regions as the first and second regions, respectively; deriving a second capture parameter for the image sensor, wherein the second capture parameter is derived by computations which implement the target range for contrast between the first and second regions; applying the second capture parameter to the image sensor; and capturing a second image of the scene by using the imaging assembly whose spectral response is tuned in accordance with the second capture parameter.
