First Claim
1. A system comprising:
- a scene processing module configured to;
receive a single frame captured by a single-chip image capture sensor having a color filter array,wherein the single frame comprisesa first set of pixel data captured by a first set of pixels of the single-chip image capture sensor that are associated with a first color filter included in the color filter array, the first color filter configured to allow light having a first color and fluorescence excitation illumination to pass through the first color filter to the first set of pixels, anda second set of pixel data captured by a second set of pixels of the single-chip image capture sensor that are associated with a second color filter included in the color filter array, the second color filter configured to allow light having a second color and the fluorescence excitation illumination to pass through the second color filter to the second set of pixels,wherein the first set of pixel data comprises a first combined scene including a fluorescence scene component, andwherein the second set of pixel data comprises a second combined scene including a combination of a visible color component scene and the fluorescence scene component,extract a display fluorescence scene component from the first combined scene,extract a display visible scene component from the second combined scene, andgenerate a plurality of weighted combinations of the display fluorescence scene component and the display visible scene component; and
a display unit connected to the scene processing module to receive the plurality of weighted combinations, and configured to generate from the plurality of weighted combinations a displayed scene including a highlighted scene component corresponding to the fluorescence scene component and a reduced color scene component.

Abstract
Mixed mode imaging is implemented using a single-chip image capture sensor with a color filter array. The single-chip image capture sensor captures a frame including a first set of pixel data and a second set of pixel data. The first set of pixel data includes a first combined scene, and the second set of pixel data includes a second combined scene. The first combined scene is a first weighted combination of a fluorescence scene component and a visible scene component due to the leakage of a color filter array. The second combined scene includes a second weighted combination of the fluorescence scene component and the visible scene component. Two display scene components are extracted from the captured pixel data in the frame and presented on a display unit.
