In a method of forming a conductive pattern structure of a semiconductor device, a first insulating interlayer is formed on a substrate. A first wiring is formed to pass through the first insulating interlayer. An etch stop layer and a second insulating interlayer are sequentially formed on the first insulating interlayer. A second wiring is formed to pass through the second insulating interlayer and the etch stop layer. A dummy pattern is formed to pass through the second insulating layer and the etch stop layer at the same time as forming the second wiring. The second wiring is electrically connected to the first wiring. The dummy pattern is electrically isolated from the second wiring.

A lens shading correction method and apparatus are provided for removing vignetting occurring in digital images due to lens shading. A white image captured by an image pickup device and an image pickup unit is separated into reference white images corresponding to color channels. A vignetting center having a maximum light intensity is estimated in each of the reference white images. Multiple reference segments on each of the reference white images are defined. A lens shading correction value corresponding to each pixel constituting the reference segments are calculated using a corresponding light intensity. A lens shading correction function corresponding to each reference segment is derived using a corresponding lens shading correction value. Vignetting of a general image received in a general image processing mode is removed, using the derived multiple lens shading correction functions.

Apparatus and method for configuring a screen for a video call using a facial expression by recognizing a face from an image, calculating facial expression information for an expression of the recognized face, and determining whether there is a change in expression of the recognized face by comparing the calculated facial expression information with reference expression information preset to determine a change in expression of the face. If there is a change in expression of the recognized face, the apparatus and method selects a video image corresponding to the changed expression in the video call screen, and reconfigures the video call screen using the selected video image, making it possible for a user to conveniently select an image of the interested person without taking extensive action, and preventing a wrong image from being selected due to the unintended user facial movement.
