1. A method for flicker reduction in a multi-imager environment, the method comprising:
producing, using a first illuminator source of a plurality of illuminator sources, a first illumination, wherein the plurality of illuminator sources comprises more than two illuminator sources, and wherein the first illuminator source produces the broadest illumination among the plurality of illuminator sources;
exposing a first image sensor during the first illumination;
generating at least one first image based on the exposure of the first image sensor;
exposing a second image sensor such that the exposure of the second image sensor is not during any pulse associated with the first illumination;
generating at least one second image based on the exposure of the second image sensor;
detecting an illuminator switch event; and
in response to the detection of the illuminator switch event:
deactivating the first illuminator source; and
producing, using a second illuminator source of the plurality of illuminator sources, a second illumination associated with at least one second illumination pulse, wherein a second field of view illuminated by the second illuminator source is different than a first field of view illuminated by the first illuminator source, and wherein the second illuminator source produces the narrowest illumination among the plurality of illuminator sources.
