Abstract
Cameras or optical devices requiring shutters to allow light to reach a light sensitive area from an object scene for a prescribed amount of time are provided with an electrically controlled light modulator to replace mechanical shutters. Cameras or optical devices requiring a variable aperture and/or transform filter to adjust the amount of light admitted, depth of focus and/or image enhancement are also provided with electrically controlled light modulators to replace mechanical apertures and transform masks. Both functions may be incorporated into a single electrically controlled light modulator.
