Abstract

A video camera includes a user interface that is used to control the supply of power to different functional portions of the camera. Power is supplied to (or not supplied to) the various functional portions of the camera based on whether a window relating to the functional portion, which is displayed on a display, is selected to be open or closed. The functional portions can include an imaging portion, an image recording portion, an image reproduction portion, a communication portion and an information processing portion, for example.
