Image capturing system

Abstract

An image capturing system for a hydrophilic optical film includes: an optical lens unit; at least one radiating module; and a brightness detection unit, wherein the hydrophilic optical film is disposed on an outer surface of the optical lens unit while the radiating module is used for radiating a light beam, wherein the radiating module is disposed at an appropriate position of an environment of the optical lens unit and cooperates with the optical lens unit to define an intersection angle, the light beam from the radiating module is radiated onto the hydrophilic optical film in order to prolong the effect of the hydrophilic optical film while the brightness detection unit upon detecting an external brightness activates the radiating module such that the light beam radiated from the radiating module has a wavelength ranging from 360-400 nano meter.
