Disclosed is an optical assembly having a first variable transmission layer comprising a first electro-optically active material between a first pair of substrates, a second variable transmission layer comprising a second electro-optically active material between a second pair of substrates, and an electronically switchable birefringent layer, that is capable of altering the phase of incident light, situated between the first and second variable transmission layers. The layers are arranged such that light passing through the optical assembly can be altered based on the voltage applied to each layer. The light transmission levels can be altered between maximally transmissive, minimally transmissive, and semi-transparent levels between the maximally and minimally transmissive levels.

A transmittance-variable film and a use thereof, where the transmittance-variable film can control pretilt of a liquid crystal interface by applying a liquid crystal alignment film containing splay oriented liquid crystal molecules, and can vertically and horizontally orient a liquid crystal layer or a liquid crystal interface according to an average tilt angle of the liquid crystal alignment film to ensure uniformity of driving and fast response speed. In addition, by applying a liquid crystal alignment film, the transmittance-variable film can be implemented in various modes with a simple coating-drying-curing method excluding the rubbing process by controlling an arrangement of liquid crystal molecules in a liquid crystal alignment film other than the pretilt control method using the conventional rubbing method.

Some implementations relate to determining whether glare is present in captured image(s) of an object (e.g., a photo) and/or to determining one or more attributes of any present glare. Some of those implementations further relate to adapting one or more parameters for a glare removal process based on whether the glare is determined to be present and/or based on one or more of the determined attributes of any glare determined to be present. Some additional and/or alternative implementations disclosed herein relate to correcting color of a flash image of an object (e.g., a photo). The flash image is based on one or more images captured by a camera of a client device with a flash component of the client device activated. In various implementations, correcting the color of the flash image is based on a determined color space of an ambient image of the object.

An electronic device includes a solar cell, a first light modulating layer, a transmittance-adjustable lens and a control circuit. At least a portion of the first light modulating layer is disposed on the solar cell. The control circuit is electrically connected to the solar cell and the transmittance-adjustable lens.
