Abstract: An apparatus for identifying a counterfeit bill is provided. The apparatus includes a camera module configured to receive a captured IR image of a bill; a binary image generator configured to generate a binary image of the bill, based on the IR image; a distance value calculator configured to compare a predetermined area of the binary image with a predetermined area of a pre-stored real bill database corresponding to the predetermined area of the binary image; and a corrected image generator configured to generate a corrected image based on a result of the comparison.

Abstract: An apparatus and a method related to an application of a mobile terminal using an augmented reality technique capture an image of a musical instrument directly drawn/sketched by a user to recognize the particular relevant musical instrument, and provide an effect of playing the musical instrument on the recognized image as if a real instrument were being played. The apparatus preferably includes an image recognizer and a sound source processor. The image recognizer recognizes a musical instrument on an image through a camera. The sound source processor outputs the recognized musical instrument on the image on a display unit to use the same for a play, and matches the musical instrument play on the image to a musical instrument play output on the display unit.

Abstract: A method of constructing a database in a mobile communication terminal includes analyzing one of a file attribute and a database field type of the received file when the file is received, determining whether the analyzed one of the file attribute and the database field type is identical to a field type of the database in the mobile communication terminal, and updating a database table in the mobile communication terminal according to the determination.

Abstract: A mobile communication device and method for identifying a counterfeit bill are provided. In the method, an InfraRed (IR) image of a bill is received, feature values are extracted from the IR image to represent edges, a binary image having displayed pixels and non-displayed pixels is generated based on the feature values, and a corrected image is generated by overlaying the binary image on a pre-stored real bill database and adjusting the binary image to match a predetermined area of the binary image matches to the predetermined area of the real bill database. A number of displayed pixels in the corrected image is counted, and whether the bill is counterfeit is based on the number of displayed pixels in the corrected image.

Abstract: An apparatus and method for defining objects representing respective applications, verifying an object used as an input tool by a user through an input size and an input shape which are input on a touch screen, and executing an application defined by the verified object. The apparatus preferably includes an object analyzing unit for verifying a touch input size and identifying a type of an object input on the touch screen and a controller for executing an associated application that corresponds to or is linked with the identified object.

Abstract: An apparatus and method for providing a touch input in a portable terminal are provided. In particular, an apparatus and method capable of determining through tactile sense a plurality of input buttons included in a virtual input window, which is displayed on a touch screen of the portable terminal are provided. The apparatus includes a pattern apply unit for applying a pattern used to determine an activation of an input button, the pattern being provided on a layer having a plurality of tactile materials during a touch input mode. When a power is supplied, an arrangement position of the tactile materials is changed according to the applied pattern, and a controller for controlling the pattern apply unit to determine the input button, position, or location of the input button through tactile sense.

Abstract: A key structure is disclosed in which the use of space for a keypad is maximized, thereby allowing free key inputs. The key structure includes a first keypad layer converted into a transparent state and a semi-transparent state, for displaying characters and numbers printed on the first keypad layer when the first keypad layer is in the semi-transparent state while displaying characters and numbers printed on a second keypad layer when the first keypad layer is in the transparent state. The key structure further includes the second keypad layer displaying characters and numbers printed on the second keypad layer by using light emitted from a light source when the first keypad layer is in the transparent state, and the light source emitting light to the second keypad layer when the first keypad layer is in the transparent state.

Abstract: A method and apparatus for acquiring DRM contents in a mobile communication terminal at a reduced expense by acquiring information about the DRM contents provided through a plurality of content providers are provided. The method and apparatus for acquiring DRM contents includes acquiring price information for DRM contents provided from a plurality of content providers upon request for acquiring DRM contents, selecting a content provider using the acquired price information and acquiring the DRM contents and a license from the selected content provider. Therefore, DRM contents can be acquired by selecting the least expensive DRM content provider at a present point in time using a content information server in which the content information is stored and then connecting to the corresponding content provider to ultimately reduce the cost for acquiring the DRM contents.
