Patent Images

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.
