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.
