Abstract:
This disclosure relates to image capture devices with the ability to perform adaptive white balance correction using a switchable white reference (SWR). In some embodiments, the image capture device utilizes “true white” information to record images that better represent users' perceptions. In other embodiments, the same SWR and camera that dynamically sample ambient lighting conditions are used to determine “true white” in near real-time. In other embodiments, the image capture device comprises a display screen that utilizes the “true white” information in near real-time to dynamically adjust the display. In other embodiments, face detection techniques and/or ambient light sensors may be used to determine which device camera is most closely-aligned with the direction that the user of the device is currently looking in, and using it to capture a “true white” image in the direction that most closely corresponds to the ambient lighting conditions that currently dominate the user's perception.
