Classification: CPC G  H | IPC G  H

Claim 17:
18. An imaging system, comprising:
at least one first light-emitting diode (LED) configured to emit first light toward a scene;
at least one second LED configured to emit second light toward the scene, the first light and the second light having different spectral profiles;
at least one camera configured to capture images of the scene;
at least one processor; and
memory coupled to the at least one processor, the memory configured to store instructions that, when executed by the at least one processor, cause the at least one processor to execute operations, the operations comprising:
causing the at least one first LED to illuminate the scene with the first light during a first time duration;
capturing, with the at least one camera, a first image of the scene during the first time duration;
analyzing pixel values of at least some pixels of the first image to determine a first color point associated with the first image;
causing the at least one second LED to illuminate the scene with the second light during a second time duration;
capturing, with the at least one camera, a second image of the scene during the second time duration;
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;
capturing, with the at least one camera, 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 selected such that the final image is associated with the third color point.
