Abstract
A portable consumer electronics device has a handheld portable device housing, and an electronic camera module integrated in the housing. The module has a focusing lens with an optical axis, an imaging sensor to receive the focused light, and an electro-optic variable aperture to allow different amounts of focused light to reach the imaging sensor. The aperture has a stack that includes a front transparent conductor medium, an electrolyte medium, an active electro-chromic medium, and a rear transparent conductor medium. The front transparent conductor medium contains an outer region and an inner region. The inner region is aligned with the optical axis, surrounded by the outer region, and electrically isolated from the outer region. Other embodiments are also described and claimed.
