Abstract
A videophone apparatus and a method for automatically adjusting a videophone visual indicator are provided. The videophone includes a camera unit with an imager. Data from the imager and imager data processed by an image signal processor may be converted into a value that can be compared to a scale correlating to a brightness condition of an area in which the imager is located, allowing the brightness condition to be determined. The visual indicators of the videophone can be set to illuminate based upon the determined brightness condition. Thus, the brightness condition of a room can be determined using components already found on the videophone, without the need for additional sensors, hardware or software that increase the cost and complexity of the videophone.
