A method of displaying a colorized luma image includes illuminating tissue under observation with illumination light and excitation light. A color image from reflectance of the illumination light and a fluorescence image produced by illuminating the tissue under observation with the excitation light are simultaneously detected at an image sensor to produce image data comprising both color image data and fluorescence image data. A luma image from the detected color image data is computed and the luma image is colorized based on the detected fluorescence image data. The colorized luma image is then displayed.

Imaging systems and methods for displaying fluorescence and visible images

An endoscopic video system and method using a camera with a single color image sensor, for example a CCD color image sensor, for fluorescence and color imaging and for simultaneously displaying the images acquired in these imaging modes at video rates in real time is disclosed. The tissue under investigation is illuminated continuously with fluorescence excitation light and is further illuminated periodically using visible light outside of the fluorescence excitation wavelength range. The illumination sources may be conventional lamps using filters and shutters, or may include light-emitting diodes mounted at the distal tip of the endoscope.
