Apparatus and method for detecting and connecting counterpart device by capturing image of counterpart device in wireless device

摘要

An apparatus and a method detect and connect a counterpart device by capturing an image of the counterpart device in a wireless device. A Relative Distance Value (RDV) between the wireless device and the counterpart device is determined via image capture using a camera. The counterpart device is identified using the determined RDV.

1. A method for operating a wireless device in a network environment where the wireless device and a counterpart device exist, the method comprising:
registering, to a database, the counterpart device to be connected for performing at least one function by mapping a relative distance value (RDV) to a captured first image of the counterpart device; capturing a second image of the counterpart device; identifying the counterpart device by comparing the captured second image of the counterpart device with at least one image registered in the database; and performing a function determined in advance between the wireless device and the counterpart device in the captured second image, wherein the registering the counterpart device further comprises obtaining height information of a counterpart device based on a device type of the counterpart device, determining a shooting distance based on the height information of the counterpart device, and determining the RDV of the counterpart device based on the determined shooting distance, an image proportional constant, and a focal length proportional constant, wherein the image proportional constant is determined by comparing a size of the counterpart device in the captured first image with a size of a focus zone on a display of the wireless device, and wherein the focal length proportional constant is determined by comparing a shooting focal distance of captured first image with a basic focal distance.
