Abstract: Provided is an apparatus and method for eliminating an outband interference signal. An apparatus for eliminating an interference signal includes a first mixer, a filter unit, a second mixer, and an operation unit. The first mixer downconverts a received signal containing an outband interference signal. The filter unit extracts the downconverted outband interference signal from the downconverted received signal. The second mixer upconverts the downconverted outband interference signal to restore the outband interference signal to the original frequency band. The operation unit subtracts and eliminates the restored outband interference signal from the received signal.

Abstract: Techniques, apparatus and system for correcting moving image wavering are disclosed. An apparatus includes a selecting unit to select at least one reference macroblock from an input image of a first frame and to select at least one search area from an input image of a second frame. The selected at least one search area corresponds to the at least one reference macroblock. The apparatus includes an operating unit to communicate with the selecting unit and to perform a statistical operation by matching the at least one reference macroblock of the first frame to each of search blocks included in the at least one search area of the second frame. The apparatus comprises a vector calculating unit to communicate with the operating unit and to calculate a motion vector to correct an output image of the second frame based on a resultant value of the statistical operation.

Abstract: Provided is an image edge correction apparatus and method. The image edge correction apparatus includes an edge information extraction unit extracting edge information of an input image based on luminance change directivity information of the input image and an edge enhancement unit enhancing an edge of the input image by applying different luminance weights to a pixel of interest included in the input image based on the edge information of the input image. Thus, by appropriately enhancing a contour portion of an image while minimizing noise in a plane portion of the image, the sharpness of the image can be improved.

Abstract: An optical data apparatus has a first polarization splitter configured to receive an input and split the input into first and second orthogonal polarizations. A second polarization splitter is included and configured to combine the first and second orthogonal polarizations. A non-reciprocal phase rotator is positioned between the first and second polarization splitters. At least one birefringent crystal is positioned between the first and second polarization splitters to create wavelength dependent bi-directionality.

Abstract: A method for allocating an optimum amount of bits to MPEG audio data at high speed. A signal-to-mask ratio obtained through a psychoacoustic model is divided by 6 and the resultant integer quotient is defined as an array pointer. A valid bit allocation amount is obtained at the high speed according to the defined array pointer. The obtained valid bit allocation amount is compared with a fixed bit allocation amount. An optimum bit allocation amount is obtained in accordance with the compared result. Therefore, according to the present invention, the optimum bit allocation amount to the MPEG audio data can be obtained at the high speed with no unnecessary loop repetition by using the signal-to-mask ratio obtained through the psychoacoustic model.
