Patent ID: 8797464

Claim:
An apparatus for controlling home network devices including a user controlled light pointing device, the apparatus comprising: a display unit that displays on a control device a device list containing items corresponding to a plurality of controlled devices arranged in a predetermined space; a receiving unit that receives a first image containing the plurality of controlled devices, the device list, and light information on light reflected from a controlled device of the plurality of controlled devices; and a control unit that maps the controlled device and an item corresponding to the controlled device according to the light information detected from the received first image, wherein the first image further contains the control device controlling the plurality of controlled devices, and wherein the display unit displays a mesh pattern having a certain color to correspond to a display area of the display unit, wherein the receiving unit receives a second image including the mesh pattern, wherein the control unit detects the display area of the control device by scanning an area in the received second image where the mesh pattern exists, detects areas of the controlled devices in the received second image by using an edge detection algorithm, determines a controlled device pointed by the light pointing device in the detected areas of the controlled devices, and displays a control menu for the determined controlled device on the display unit, and wherein the apparatus further comprises a compensating unit that compensates a display area of the second image by comparing the mesh pattern displayed on the display area and a mesh pattern detected in the received second image.
