Abstract: A dryer is provided, which includes a communicator configured to perform communication with a server that is connected to a network, and a processor configured to receive washing information that is pre-stored in the server from the server and to set a drying course for drying laundry that is put into the dryer based on the washing information.

Abstract: The present invention relates to a method and apparatus for creating a 3D image of vehicle surroundings. The method according to the present invention includes the steps of: mapping images captured by a plurality of cameras installed in a vehicle to a virtual plane defined by a 3-dimensional space model having a container shape with a flat bottom surface and a top surface which has an increasing radius; and creating a view image having a viewpoint of a virtual camera by using the image mapped to the virtual plane. According to the present invention, it is advantageous that an image of vehicle surroundings including surrounding obstacles can be expressed naturally and three-dimensionally. It is also advantageous that an optimal image of vehicle surroundings can be provided by changing the virtual viewpoint according to a traveling state of the vehicle. There is also the advantage that a user can conveniently adjust the viewpoint of the virtual camera.

Abstract: Disclosed is a refrigerator having a dispenser comprising: a dispenser case mounted at one side of a refrigerator door; a cold water faucet and a hot water faucet provided in the dispenser case and from which cold water and hot water are supplied; and a dispenser door for opening and closing the dispenser case. In this construction, a hot water button is prevented from being pressed by a child by mistake and thus a child is prevented from getting burned by hot water from the hot water faucet, thereby enhancing a stability. Also, when a cup or a container becomes hot while or after the user gets hot water from the hot water faucet in the cup or the container, the cup or the container can be placed on the dispenser door thereby to enhance the user's convenience.
