## Abstract

An electronic device having a camera and a touch-sensitive display supports methods for capturing an image using a movable shutter button thereon. The electronic device executes a camera application that may have a single movable displayed on the touch sensitive display, or two shutter buttons, one of which is fixed and one of which is movable. Where two shutter buttons are used, the second button may be present when the camera application is executed, or may be created in response to the user inputting a gesture to move the first shutter button.
