Abstract
An imaging system comprises a rolling shutter sensor that captures images of a scene, an illumination source that continuously illuminates the scene, a time-varying illumination source that illuminates the scene, and a processor that receives the images from the rolling shutter sensor. The rolling shutter sensor and the time-varying illumination source are operated synchronously to cause: on-cadence lines of the rolling shutter sensor to receive illumination from the continuously illuminating illumination source and a first amount of illumination from the time-varying illumination source; and off-cadence lines of the rolling shutter sensor to receive the illumination from the continuously illuminating illumination source and a second amount of illumination from the time-varying illumination source. The processor separates the images into feeds based on the first and second amounts of illumination by combining the on-cadence lines to generate a first feed and combining the off-cadence lines to generate a second feed.
