Claim 15:
16. An imaging system comprising:
a time-varying illumination source that illuminates a scene;
a rolling shutter sensor that captures image data, the rolling shutter sensor operated synchronously with the time-varying illumination source;
a continuous illumination source that illuminates the scene; and
a processor configured to:
determine on-cadence lines and off-cadence lines from the captured image data;
determine a contribution of the time-varying illumination source to an overall illumination in the image data; and
generate a plurality of feeds with different contributions of the time-varying illumination source to the overall illumination, wherein the plurality of feeds comprise a general-purpose feed from which the contribution of the time-varying illumination source to the overall illumination of a scene is removed and a special-purpose feed in which the contribution of the time-varying illumination source is isolated.
