  • Printed circuit board having embedded resistors and method of manufacturing the same
    Publication number: 20080110669
    Abstract: Disclosed herein is a Printed Circuit Board (PCB) having embedded resistors and a method of manufacturing the same, in which contact pads are formed by filling via holes formed on electrode pads with oxidation-resistant conductive material, and resistors are formed on the contact pads. Accordingly, erosion that occurs between the electrode pads and the resistors can be prevented using the contact pads made of oxidation-resistant conductive material, and connections between circuits also can be realized. Furthermore, resistors are formed on a flat plane without any difference in height, attributable to the electrode pads, and thus differences between the resistance values of the built-in resistors can be greatly reduced.

    Publication number: 20080112639
    Abstract: A method and apparatus for removing noise in a dark area of an image are provided. An edge magnitude in an N×N window image including a plurality of pixels is calculated. It is determined whether an edge area is present in the window image on the basis of the edge magnitude. A mean value of brightness of the window image is calculated when the edge area is not present. It is determined whether the window image corresponds to a bright area or a dark area on the basis of the mean value. The window image is determined as the bright area when the mean value is higher than a preset brightness reference value, and low-pass filtering is performed on the window image. The window image is determined as the dark area when the mean value does not exceed the reference value, and minimum filtering is performed on the window image.
