Classification: CPC G  H | IPC G  H

Claim 9:
10. A method for operating an imaging system, the method comprising:
receiving data corresponding to a first image of a scene while the scene is illuminated with first light;
analyzing pixel values of at least some pixels of the first image to determine a first color point associated with the first image;
receiving data corresponding to a second image of the scene while the scene is illuminated with second light, the first light and the second light having different spectral profiles;
analyzing pixel values of at least some pixels of the second image to determine a second color point associated with the second image, the first color point and the second color point having respective locations in a plot having a first axis and a second axis, the first axis indicating values of a ratio of a sum of at least a subset of pixel values of a first primary color to a sum of at least a subset of pixel values of a second primary color, the second axis indicating values of a ratio of a sum of at least a subset of pixel values of a third primary color to the sum of at least the subset of pixel values of the second primary color;
receiving data corresponding to a third image of the scene under ambient lighting;
analyzing pixel values of at least some pixels of the third image to determine a third color point associated with the ambient lighting; and
generating a final image as a weighted average of the first image and the second image, the weighted average being dependent on the first color point, the second color point, and the third color point.
