Abstract: A method for displaying a three-dimensional (3D) image includes: alternately displaying a left eye image and a right eye image; calculating a luminance value of a displayed image to detect a peak value of a luminance value; comparing the detected peak value and a stored peak value, and when the detected peak value corresponds to a right eye peak value, determining that a current image is a right eye image, and when the detected peak value corresponds to a left eye peak value, determining that the current image is a left eye image; outputting a synchronization signal according to the determination result; and making the left eye image and the right eye image reach a user's left eye or right eye according to the synchronization signal.

Abstract: A setting apparatus of an antenna for satellite broadcasting in a satellite broadcasting system includes a receiving device coated with a fluorescent material whose color varies depending on a level of a voltage applied thereto, for receiving a satellite broadcast signal; and a controlling unit coupled to the receiving device for applying a driving power source to the fluorescent material of the receiving device, depending on a level of the satellite broadcast signal received in the receiving device.
