Abstract:
Various image-capturing systems are disclosed that use polarized filters to reduce or control glare effects on captured images. In one embodiment, the system includes a light source, a first polarized filter adapted to polarize light emanating from the light source; a second polarized filter adapted to perform polarized filtering on received light; and an image-capturing device adapted to receive the filtered light. In another embodiment, the system further includes an actuator to selectively move any of the polarized filter into and out of the light path. In yet another embodiment, a method of forming a resultant image comprises recording a first image with a filter set to a first polarization angle, recording a second image with the filter set to a second polarization angle, and blending the first and second images. The recording of the first and second images may be performed simultaneously or at different times.
