1. An endoscopic video system comprising:
a light source adapted to provide white light illumination at a first frame rate suitable for live video, and to interrupt the white light illumination and provide narrowband illumination for individual frames interspersed among the white light illuminated frames at regular or irregular intervals, wherein the spectrum of the narrowband illumination varies amongst the interspersed frames sufficient for a series of at least two differently illuminated narrowband interspersed frames to be assembled into a multispectral or hyperspectral data cube at a second frame rate; and
a processor adapted to receive an image signal based on sensor data received from a focal plane array sensor and create a live video feed based on the white light illuminated frames by replacing the narrowband illuminated frames with frames generated from one or more time-adjacent white light illuminated frames, and to generate the multispectral or hyperspectral data cube at a second frame rate based on the narrowband illuminated frames.
