Abstract
An imaging system and method includes a rolling shutter sensor that captures a plurality of images of a scene, a time-varying illumination source that illuminates the scene, and a processor that receives the plurality of images from the rolling shutter sensor and separates the plurality of images into a plurality of feeds. Each of the plurality of images is captured as a series of lines. The rolling shutter sensor and the time-varying illumination source are operated synchronously to cause a plurality of on-cadence lines of the rolling shutter sensor to receive more illumination from the time-varying illumination source than a plurality of off-cadence lines of the rolling shutter sensor. Each of the plurality of feeds has a different contribution of the time-varying illumination source to an overall illumination of the scene.
