1. A lens actuation system for an endoscope, the system comprising:
- at least one viewing element configured to capture images;
a plurality of illuminators configured to illuminate a plurality of fields of view (FOVs) associated with said at least one viewing element;
a controller; and
at least one actuatable lens positioned in front of one of said plurality of illuminators, wherein said at least one actuatable lens is configured to dynamically change an illumination direction of said one of the plurality of illuminators based upon a signal from said controller.

Abstract
A lens actuation system for an endoscope comprises at least one viewing element configured to capture images, a plurality of illuminators configured to illuminate a plurality of fields of view (FOVs) associated with the at least one viewing element, a controller, and actuatable lenses positioned in front of at least one of the plurality of illuminators and/or in front of the at least one viewing element. The actuatable lenses are configured to change dynamically a) an illumination direction of the at least one of the plurality of illuminators, and/or b) a direction of incoming light beams to the at least one viewing element.

20. A method of controlling illumination of an endoscope tip, the method comprising:
-
providing, at said endocope tip, at least one viewing element configured to capture images, a plurality of illuminators configured to illuminate a plurality of field of views (FOVs) associated with said at least one viewing element and at least one actuatable lens positioned in front at least one of the plurality of illuminators; receiving, from said at least one viewing element, images of a plurality of FOVs illuminated by said plurality of illuminators; and
,dynamically redirecting illumination by actuating said at least one actuatable lens in order to reduce light intensity of a too bright captured image or increase light intensity of a too dark captured image.
