Abstract
A vehicular imaging system for capturing an image includes an imaging sensor and an electro-optic filter. The electro-optic filter is operable to attenuate light in response to a voltage applied to said electro-optic filter. The electro-optic filter is positioned along an optic path between the imaging sensor and a scene being captured by the imaging sensor. The imaging system includes a control for applying the voltage to the electro-optic filter. Preferably, the control is operable to selectively apply the voltage to the electro-optic filter. Preferably, the control is operable to selectively apply the voltage to the electro-optic filter in response to an ambient light intensity.
