A photographing apparatus comprises a movable unit, a fixed unit, and a control unit. The movable unit has an imaging device, and can be moved in a first direction. The first direction is perpendicular to an optical axis of a photographing optical system of the photographing apparatus. The fixed unit slidably supports the movable unit in the first direction. The control apparatus controls moving the movable unit to two or more movement-positions in the movable unit's movement range, and obtains a wide-angle image signal which is a combination of the two or more image signals being imaged at two or more movement-positions of the movable unit.
