  • Patent number: 5949474
    Abstract: A videophone with selective privacy control of a caller's transmitted image.

A video indicator also may be included, which separately indicates that the shutter is open. The video indicator (which may be an LED) may be located adjacent the lens so that it is visible when the shutter is open, and is covered by the shutter when the shutter is closed. Alternatively, the videophone makes use of a visual signal (such as an icon) which is displayed when the shutter is closed, separately or in combination with a video indicator which indicates that the shutter is open.
