Abstract: A camera system for object recognition is disclosed. In one aspect, the system includes an active three-dimensional (3D) sensor configured to obtain a 3D point cloud which corresponds to 3D position values of an object, and a controller configured to generate control data for controlling a zoom value, a pan value, and a tilt value which correspond to the 3D position values. The system also includes a camera configured to photograph the object by performing one or more of zooming, panning, and tilting on the basis of the control data.

Abstract: An apparatus and a method for inputting a character using user's motion is provided. When a user's hand makes a motion, a character input pattern is recognized from the motion, a character to be input is determined by comparing the recognized character input pattern with character input pattern information which predefines various character input patterns and corresponding characters, and the determined character is displayed.
