In scenes that have low lighting, it may be difficult for a personal electronic device to capture video images that meet a scene lighting criteria. In some low-lighting situations, the receiving party may be unable to sufficiently see the face of the party that they are videoconferencing with. Described herein are techniques for utilizing a device's display to illuminate the scene surrounding the device. Improved lighting may come from global display adjustments, local display adjustments that do not alter the display's contents (other than to change their brightness levels), and/or local display adjustments that alter the display's contents. In some embodiments, background elements on a device's display may be identified for brightening in a first attempt to meet the scene lighting criteria without negatively impacting foreground scene content. If such approaches are unsuccessful, the device may next replace one or more regions of displayed content with regions of brightened pixels.

Video capture in low-light conditions

Performing a real-time application on a mobile device, involving communication of audio/video packets with a remote device. The mobile device may initially communicate the audio/video packets on a first communication channel with the remote device. During the real-time communication, the mobile device may determine if no packets have been received by the mobile device from the remote device for a first threshold period of time. If no packets have been received by the mobile device from the remote device for the first threshold period of time, the mobile device may establish a second communication channel for transmission of the audio/video packets with the remote device. In response to using the second communication channel, the mobile device may modify a resolution or bit rate of the audio/video packets transmitted to the remote device.
