Summary:A system and method changes touch screen functionality based on whether a user is detected during camera operation. A first camera generates a video signal containing a representation of at least a portion of a scene within a field of view of the first camera. A controller analyzes the video signal to determine whether one or more physical features of a user of the electronic device are present within the field of view of the first camera. A touch input device includes one or more touch points for receiving user input, each touch point being associated with controlling a respective one of a plurality of functions of the second camera. At least one of the touch points is associated with controlling a shutter function of a second camera, and a total number of touch points is dependent upon a result of the video signal analysis made by the controller.
