Abstract

A system and method for controlling lighting conditions in a user environment in the context of an image capture device is disclosed as is a system and method for controlling lighting conditions whereby bandwidth consumption may be managed. An inner frame area and an outer frame area adjust certain lighting conditions in the user environment in response to certain lighting conditions detected by the image capture device; those conditions may affect and be relevant to bandwidth consumption during transmission of the image capture data. The frame areas may be dynamically controlled as to affect the brightness and/or color of the particular user environment.
