Abstract: A method of updating firmware of a near field communication (NFC) device includes copying metadata, which is included in a firmware image file, from an application processor to the NFC device. One of a certification success signal and a certification fail signal is provided from the NFC device to the application processor after the NFC device verifies an integrity of the metadata. Firmware data, which is included in the firmware image file, is copied from the application processor to the NFC device when the application processor receives the certification success signal from the NFC device.

Abstract: The present invention relates to a method and a system for card marketing which collect benefit information about member stores of various financial cards, such as credit and debit cards, used for payment from all of the affiliated card companies and manage the collected benefit information, calculate the quantity of benefits for each card with respect to expenditure details of a financial card, cash, and banking of an individual in each member store without discriminating a company's own card from cards from other companies and recommend an optimum card having the largest benefits, and connect the card benefit information to an advertisement or induce the individual to be issued a new card, thereby effectively accomplishing card marketing.

Abstract: A method and apparatus for generating a white signal component and for controlling the brightness of an image are provided. In the above method and apparatus, the brightness increases of Red, Green and Blue, the saturations of which are not decreased from an input image are calculated using a vector, and the minimum value of such increases is utilized as the input value for the white component. Further, by adding brightness control components of RGB color to the input RGB signals, brightness increases in the direction of the original colors instead of the achromatic one are possible, which is the way the white component is added so as to increase the luminance of color display devices representing a color using a color filter such a flat panel display. Accordingly, a color saturation of the image is not decreased even with addition of the achromatic color component.

Abstract: An apparatus and method for processing color images are provided. The apparatus includes a color conversion unit for white-transforming signals in RGB space. The color conversion unit includes a first white-transforming means for white-transforming signals in RGB space to signals in a predetermined color space using N predetermined illuminant colors, and a second white-transforming means for white-transforming the signals in the predetermined color space to the signals in RGB space using M predetermined color temperatures of the display means, so that a natural color image or an image of a desirable color can be obtained without information with respect to the illuminant.

Abstract: A method and apparatus for estimating illuminant chromaticity and a method and apparatus for converting the estimated illuminant chromaticity into desired illuminant chromaticity using software are provided.
