Abstract: The present invention includes the steps of: displaying an unlocking interface via a user interrupt; receiving an unlocking pattern inputted via the unlocking interface; detecting the received unlocking pattern and executing a mode corresponding to the detected unlocking pattern to thereby measure the status degree of an object corresponding to the detected unlocking pattern; and calling a lookup table in which a range of adequate status degrees for each type is measured and matched according to a pre-set and classified object type to thereby determine the status degree of the measured object, and feeding back the result of the determination via the unlocking interface.

Abstract: Disclosed are an apparatus for detecting a vertex of an image and a method for the same detecting the vertex with the high degree of accuracy and reducing time to detect the vertex by minimizing the interaction operations of the user to detect the vertex even in a touch input part having the low degree of sensing precision. The method includes inputting a vertex position of an image, setting an ROI, detecting a plurality of edges, detecting a candidate straight line group based on the edges, and removing a candidate straight line forming forms an angle less than a critical angle with respect to a base candidate straight line set from the candidate straight line group, and determining an intersection point between a remaining candidate straight line and the base candidate straight line provided at a position making a minimum distance from the input vertex position as an optimal vertex.
