An image photographing device displays a preview panoramic image and data regarding moving velocity and direction of the image photographing device during panorama photographing in real time. In one method, a transmit group to which to transmit during a first coherence time interval is selected. The water is preferably received at or travels through a water entry tube to the back and bottom of the filter. Si is prevented from being precipitated. Accordingly, it is possible to provide a semiconductor device capable of offering high density mounting schemes with increased reliability while reducing production costs.
