18 Claims

1. A method for flicker reduction in a multi-imager environment, the method comprising:

producing a first illumination using a first illuminator source of a 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 from a first field of view illuminated by the first illuminator source, wherein the second field of view illuminated by the second illuminator source is narrower than the first field of view illuminated by the first illuminator source.
