An imaging system for a portable electronic device includes a variable aperture between a lens group and an image sensor. The variable aperture is defined by an electrochromic stack that defines a switching region and a central non-switching region. The electrochromic stack is defined by a layer of electrochromic material in which an electrochromic crystallite dispersion (e.g., nickel oxide) is suspended in a field of a lithiated ion conductor layer (e.g., lithiated tungsten nickel oxide).

According to one embodiment, an electronic apparatus includes a camera, a first polarizer, a second polarizer, a liquid crystal panel, and a controller controlling the liquid crystal panel. The liquid crystal panel includes a first region and a second region. The controller controls a first opening mode of transmitting light through the first region and the second region, and a second opening mode of making a quantity of light transmitted through the first region smaller than a quantity of light transmitted through the second region.

An optical element driving mechanism is provided. The optical element driving mechanism includes a fixed portion, a first blade, a transmission assembly, and a driving assembly. The first blade is movable relative to the fixed portion. The transmission assembly is movable relative to the fixed portion. The driving assembly is used for driving the transmission element to move relative to the fixed portion. The transmission element brings the first blade to move relative to the fixed portion when the transmission element is driven by the driving assembly.
