Patent ID: 8014567

Claim:
A method for recognizing a gesture in an image processing system, the method comprising: detecting a face area in an image captured and input from a camera; dividing the image to predetermined areas with reference to a predetermined location of the face area, and setting the predetermined areas to gesture search areas; detecting a hand area in the gesture search areas; determining whether a gesture occur in the detected hand area; and selecting a detection area with respect to the gesture and transferring an image of the selected detection area as a control command for controlling an image device wherein the determining of the gesture occurrence comprises: determining a skin color of the detected hand area by determining skin-color information of the face area; calculating a differential image of the hand area between a previous frame and a current frame; combining differential-area information of the differential image with the determined skin-color information to obtain a final image; and recognizing gesture occurrence from the final image when an overlapping area between the differential area information and the skin color information is larger than a predetermined area.
