  • Patent number: 10587824
    Abstract: An imaging method includes imaging a scene having a pulsed light source and associating a symbol with the light source. The image is enhanced by inserting a symbol into the image indicative of location of the pulsed light source in the scene. The symbol overlays the image in spatial registration with the location of the pulsed light source in the scene to augment indication of the location provided by the pulsed light source. Imaging systems are also described.
