Abstract
A device includes a digital camera positioned underneath a display of the device that captures images through the display. The brightness of the display is controlled when capturing images using the digital camera to reduce interference from light emitted by the display with the captured images. The brightness can be controlled in various manners, such as reducing the brightness of only a camera region of the display that is within the field of view of the camera, reducing the brightness of only an expanded region of the display that includes a camera region of the display and an area surrounding the camera region but less than the entire display, reducing the brightness of the entire display or the brightness of only particular colors of the display, blacking out the camera region of the display, blacking out the expanded region of the display, strobing the display, and so forth.
