User equipment may provide a graphic user interface that i) displays images of payment instruments classified by a payment instrument type, ii) scrollably displays images of the classified payment instruments, iii) displays an estimated lowest payment amount for a desired purchase by combining membership benefits of payment instruments based on payment instrument images scrolled and arranged at a selection position thereof.

Abstract: The disclosure is related to a service for helping a consumer to select a payment card returning the relatively best benefits among multiple payment cards of the consumer without requiring user equipment for collecting a large amount of information and for performing excessive amount of computation. The user equipment may be configured to obtain a merchant identification code from a target merchant, to request a modularized code block associated with the obtained merchant identification code to a service server, to receive a modularized code block associated with the merchant identification code from the service server, and to display information on beneficial payment cards associated with the target merchant in a designated display area of a user interface of a service application, installed in and executed by the user equipment, by processing the received modularized code block.

Abstract: An image stabilizer includes: a correction lens module that comprises a correction lens and a correction lens supporting plate to which the correction lens is coupled; a magnet that is fixed to the correction lens supporting plate; a driving unit that is disposed to face the magnet and reacts to the magnet so as to move the correction lens module in a first direction perpendicular to an optical axis and in a second direction perpendicular to the first direction; a detecting unit that is disposed to face the magnet opposite the driving unit and detects movement of the correction lens module; and a magnetic body that is disposed to face the magnet to restore the correction lens module to an initial position thereof and is placed on a same plane as the detecting unit.

Abstract: A lens barrel and a photographing apparatus comprising the lens barrel include: a lens module that comprises at least one lens and moves along an optical axis of the at least one lens; a shake correction module arranged near the lens module; at least one fixing member that is disposed between the lens module and the shake correction module and fixes the shake correction module in response to being pressed by the lens module; a frame on which the at least one fixing member is installed; and at least one elastic member that elastically mounts the at least one fixing member on the frame.

Abstract: An optical device includes an optical element through which light is transmitted, a frame that supports the optical element, magnets in the frame around the optical element, a base unit that movably supports the frame, a cover unit to cover the magnets, and magnetic force generating units in the cover unit in positions corresponding to the magnets and that generate magnetic force when an electrical signal is applied.

Abstract: A light amount adjusting apparatus includes: a two-dimensional (2D) aperture assembly that adjusts an opening area of a via hole through which light is transmitted; a three-dimensional (3D) aperture plate that forms a first opening and a second opening by blocking a part of the via hole, or moving to outside of the via hole to open the via hole; a first shielding plate that is movable to open or close the first opening; and a second shielding plate that is movable so as to close the second opening when the first shielding plate opens the first opening and to open the second opening when the first shielding plate closes the first opening.

Abstract: Provided is a digital photographing apparatus and method of obtaining data of a clear image even though the digital photographing apparatus shakes. The digital photographing apparatus includes: a lens; an imaging device generating data from light incident through the lens; an imaging device base on which the imaging device is disposed; a light diode integrated circuit disposed on the imaging device base; and an imaging device base actuator moving the imaging device base and controlling a position of the imaging device. The method comprises generating data from light incident through a lens; detecting a direction of shake of the digital photographing apparatus according to a difference in the amount of light detected in each of four regions of the surface of a light diode integrated circuit; and changing a position of the imaging device in the opposite direction to the detected direction of the shake.

Abstract: The object of this invention is to provide a method for moving a cursor using numerical keys. In the cursor movement method, a screen of an information device is divided into sub-screens each. The sub-screens are mapped to respective numerical keys provided on the information device. It is determined whether the numerical keys mapped to the sub-screens have been pressed. The cursor is moved to a sub-screen mapped to a corresponding numerical key and displaying the cursor if it is determined that a numerical key has been pressed. Accordingly, the present invention can easily move the cursor to a desired location in an information communication device lacking a mouse. Therefore, the present invention can perform a function similar to a mouse when a user plays a game, etc. using an information communication device lacking a mouse, such as a mobile phone.
