Abstract: PURPOSE: A method for recognizing a pointer controlling command according to a finger movement and a mobile terminal for controlling a pointer according to the finger movement are provided to recognize a drag and drop command, thereby performing a controlling operation with various methods. CONSTITUTION: An image is about a finger area is obtained(S101). An outline of the finger area is extracted from the obtained image(S105). A skeleton is extracted from the obtained image by using the extracted outline(S107). A coordinate of a pointer corresponding to the finger area is extracted based on the extracted outline(S109). A change of the pointer according to a finger movement is observed(S111). A control command is operated according to an observation result(S127). [Reference numerals] (AA) Start; (BB) Smooth moving of a pointer; (CC) Sharp change of a finger contour; (DD) Stop of the pointer; (EE) End; (S101) Obtaining a finger area image; (S103) Preprocessing of the finger area image; (S105) Extracting the finger contour; (S107) Skeletonization(extracting a skeleton); (S109) Extracting a coordinate(the pointer) of a finger area; (S111) Observing a pointer change according to finger motion; (S115) Moving pixel change and direction measurement of the pointer between frames; (S117) Control command recognition in top, bottom, left and right direction; (S119) Finger area adjustment sensing; (S121) Click control command recognition; (S123) Location time determination on an object; (S125) Selection control command recognition; (S127) Control command performance

Abstract: PURPOSE: A pointer recognition method according to the movement of a finger and control command recognition method thereof are provided to improve the convenience of a user by controlling the program of a portable information terminal through the movement of a finger. CONSTITUTION: A video acquisition apparatus which is installed at the rare surface unit of a portable information terminal acquires video including a finger area(S101). A binary video is created by performing binary-coding for the video including the finger area. An image is created by eliminating noise. The contour line of the finger area is extracted from the image(S105). The center line of the finger area is extracted from the contour line of the finger area(S107). The end part of the center line is extracted from the finger area using a pointer(S109).
