Abstract
Abstract A mode changing device for a camera employing a minimum number of actuating members to permit a user to change an operating mode and/or setting of the camera. A mode actuating member and a selector switch, used in conjunction with an LCD panel that indicates the mode and setting that has been selected by the user, permits the user to easily select and/or adjust the features of the camera, such as a photographing mode, a playback mode, an exposure mode, a white balance mode, a copy/monitor mode and a time/date mode. When the mode changing device is applied to a still video camera having a playback function, a change-over switch automatically changes the operating mode of the camera from a record mode to a playback mode when a monitoring adapter is connected to the camera, further reducing the number of actuating members that are needed to control the camera. In addition, the camera is designed to minimize the waste of electrical power by inhibiting the operation playback mode until the camera is instructed to begin operating.
