Portable terminal and user interface control method thereof based on pattern recognition and analysis of image captured by camera

摘要

A portable terminal (100) and a user interface control method thereof are provided. In the terminal and method, patterns of a subject image captured by a camera are recognized and analyzed. First (10) and second (12) images changed according to motion (movement, holding away from or drawing close to a user) of the portable terminal are captured by the camera module. Patterns (A,A') of the first and second images are recognized. The motion of the portable terminal is analyzed based on the recognized patterns. Control commands corresponding to the analyzed motion are selected. A function corresponding to the selected control command is performed. The portable terminal can be intuitively and simply used as its motion is directly applied to user interface control. User interface can be controlled without an additional part, using a camera installed to the portable terminal. Also, the present invention can resolve the problems caused when the conventional navigation key is operated.
