Abstract

Some embodiments include a mobile device with a light sensor overlaid under a display (e.g., a touchscreen). The mobile device can identify a command to capture an image. The mobile device can adjust at least a target portion of an opaqueness adjustable region of the display directly over the light sensor. The opaqueness adjustable region is capable of transforming from substantially opaque to substantially transparent. The mobile device can capture the image utilizing at least the light sensor while the target portion of the opaqueness adjustable region is substantially transparent.
