A camera captures visual images from light passed through a lens aligned with an image sensor and interfaced with an image signal processor. A non-mechanical aperture coupled at the lens adjusts the camera aperture with plural areas selectively blocked from passing light by application of an electric field to a liquid crystal layer. Orthogonal polarizers on the front and rear sides of the liquid crystal layer block passage of light when an electric field is absent and selectively pass light with incremented decrease of the camera aperture as areas of concentric circles from a center out to a perimeter once an electric field is applied.
