When no photographing is carried out, a control unit applies no voltage to a dimming film of a lens concealing plate, sets a light blocking state to scatter incident light, and prevents a camera lens from becoming visible. When an operator depresses a photographing mode selection key, the control unit applies a predetermined voltage to the dimming film to set a transparent state, thereby enabling photographing to be carried out. In this state, when photographing a landscape, the operator directs the camera lens to an object, sets a cellular phone ready, decides a composition by watching an image of the object displayed on a main display unit, and correcting a position of the cellular phone, and depresses the photographing mode key again.
