A method is provided for supporting mobility of a Mobile Node (MN) in a multi-hop Internet Protocol (IP) network, in which an MN that has moved from a source Personal Area Network (PAN) to a target PAN, sends a Router Solicitation (RS) message with an option for requesting its profile to a gateway of the target PAN, and receives a Router Advertisement (RA) message from the gateway in response to the RS message. The RA message includes a home prefix of the MN as the requested profile. The method supports mobility of MNs, enables unicast communication, and facilitates efficient use of the network.

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.

For fabricating an image sensor, an isolation structure is formed to define a first active region of a semiconductor substrate. A first transistor and a second transistor of a unit pixel are formed in the first active region. In addition, a threshold voltage lowering region is formed in a portion of the semiconductor substrate near a portion of the isolation structure abutting the second transistor in the first active region. The threshold voltage lowering region causes the second transistor to have a respective threshold voltage magnitude that is lower than for the first transistor. The threshold voltage lowering region is formed simultaneously with a passivation region in a second active region having a photodiode formed therein.

A method and an apparatus are provided for adjusting white balance of a digital image. An input image is converted into a YCbCr color space. White pixels of the converted input image are detected by determining whether each pixel of the converted input image is included in a preset region of the YCbCr color space. A gain of each channel is calculated from averages of R, G and B values of the detected white pixels. White balance adjustment is performed by applying the calculated gain of each channel to each pixel of the input image.
