Abstract: A method of displaying wallpaper and an apparatus for displaying wallpaper includes displaying an input image to be displayed on wallpaper as a background image and a wallpaper displaying frame containing the entire image or a part of the input image on a wallpaper setting window, modifying a wallpaper displaying frame area according to a user's instruction, and displaying the modified frame area on the wallpaper. The apparatus for displaying wallpaper includes an application unit that displays an input image to be inputted as a background image for wallpaper and a wallpaper displaying frame containing the entire input image or a part of the input image on a wallpaper setting window, a modification unit that modifies a wallpaper displaying frame area specified by the application unit according to a user's instruction, and a wallpaper displaying unit that displays the frame area modified by the modification unit on the wallpaper.

Abstract: A wireless communication terminal having a function of automatically controlling an intensity of radiation of a flash, and a method thereof are disclosed. The wireless communication terminal includes: a camera module for capturing an image of a subject through an auto-focusing function; a controller for outputting a charge control signal corresponding to a focus distance value of a focusing lens that gives the maximum sharpness of an image based on calculation in the camera module, and transferring an activation signal according to an image signal; a power supply for supplying electric power according to the charge control signal to the controller; and a light emitting unit for producing an instantaneous flash of light according to the activation signal from the controller by receiving the electric power from the power supply.

Abstract: A wireless communication terminal having a function for automatically controlling a flash and a method thereof are disclosed. The wireless communication terminal includes: an image capturing unit for obtaining an image of an object in real-time, converting the obtained image to an electric image signal, and automatically controlling a gain according to brightness of the electric image signal; an input unit for receiving an image capturing signal; a controller for confirming a gain value of an image signal which is automatically controlled in the image capturing unit when the image capturing signal is inputted through the input unit, comparing the confirmed gain value of the image signal with a predetermined threshold value, and generating a control signal according to the comparison signal; and a light emitting unit for emitting light in response to the control signal from the controller.

Abstract: A wafer transfer system, and method of controlling pressure in the system, includes a loadport for receiving a wafer container, a housing operably connected to the loadport, a wafer transfer mechanism for transferring a wafer between the wafer container and the housing, a wafer container sensor for detecting a presence of the wafer container on the loadport, a variable speed fan disposed in a first portion of the housing, a variable exhaust unit disposed in a second portion of the housing facing the first portion, the variable exhaust unit being capable of varying an exhaust rate of air from the housing, and a controller for variably operating the variable speed fan and the variable exhaust unit in response to a signal from the wafer container sensor.
