Abstract: Disclosed is a core for a current transformer, which forms an upper core in a round shape, and is disposed at a position lower than the center of a power line having both ends of the upper core received, thereby minimizing the stress of a magnetic path, and increases the permeability, thereby enhancing the magnetic induction efficiency. The disclosed core for the current transformer includes an upper core curved in a semi-circular shape to have a receiving groove formed therein, and having both ends extended downwards to be disposed to be spaced apart from each other and a lower core disposed on the lower portion of the upper core, and having both ends extended upwards to be disposed to face both ends of the upper core.

Abstract: Disclosed is an intelligent display method for a multimedia mobile terminal. The method includes the steps of determining a type of a camera shot existing in a sport game video; deciding a region of interest within an image frame of the sport game video when it has been determined that the camera shot is a long-distance shot, magnifying the region of interest, and displaying the region of interest on the mobile terminal, and displaying the entire image frame on the mobile terminal when it has been determined that the video shot is a non-long-distance shot. The method enables the user to watch images in a more understandable and comfortable manner.
