Abstract: Disclosed herein is a method for paying a commodity using a device. The method may include the steps of (a) obtaining commodity information by scanning barcode of a commodity, (b) recognizing a first gesture of a user, (c) sending the obtained commodity information to a server in response to the recognized first gesture, and (d) receiving purchase information about the commodity whose commodity information has been obtained from the server and outputting the purchase information. There is an advantage in that a user can easily purchase a commodity without renting a cart because a gesture of the user who selects a commodity through the device can be automatically selected, the commodity can be put in a shopping basket, and payment for the commodity can be performed. In paying a commodity, additional information, such as a corresponding coupon and membership points applied to the commodity, can be provided to a user.

Abstract: There are provided an apparatus and a method for estimating edge areas of pixels in a digital image to thereby prevent an edge sharpening algorithm from being applied to non-edge area of the digital image. Therefore, the apparatus can accurately determine whether each pixel is in an edge area or in a non-edge area, by generating a binary mask obtained by using a luminance difference average between each pixel and each of neighboring pixels in the digital image. Moreover, the determination of an edge-area or a non-edge area may be applied to various digital images, by adjusting a level of edge-area determination.

Abstract: There is provided an apparatus for improving the sharpness of an image, which may prevent occurrence of distortion of an image in an edge enhancement process of the image by applying an active weight in accordance with a two-dimensional (2D) high pass filtering value of the image.
