The present invention relates to a plasma display apparatus and a method for processing image thereof. The plasma display apparatus according to the present invention comprises a gray-level signal division part for dividing a gray-level signal during one frame into a first gray-level signal and a second gray-level signal, a high pass filter for filtering the first gray-level signal through high frequency bandwidth and a low pass filter for filtering the second gray-level signal through low frequency bandwidth.

The present invention relates to a treatment agent for diabetic complications, and a method for the treatment of diabetic complications using the same. The present invention confirmed that Osteomeles schwerinae extract and its fractions inhibited the generation of AGEs, the index for diabetic complications, inhibited the activation of aldose reductase, had anti-cataract activity, and had anti-oxidative activity. Thus, the present invention relates to a preventive and therapeutic agent for diabetic complications containing the said Osteomeles schwerinae extract and its fraction as an active ingredient.

Disclosed herein is a method and apparatus for driving a plasma display panel in which signal distortion can be minimized while reducing contour noise. According to the present invention, the method of driving the plasma display panel includes the steps of performing a first inverse gamma correction operation on externally inputted video data, performing a confined error diffusion operation on the first inverse gamma corrected video data within a range of a dither mask pattern of an upper gray scale, dithering the confined error diffused video data by using a plurality of dither mask patterns which are separated every gray scale and every frame, performing a second inverse gamma correction operation on the dithered video data, and mapping the second inverse gamma corrected video data to a sub-field pattern in which one frame includes one or more selective writing sub-fields and one or more selective erasing sub-fields.

A data modulation method and a data error correction method are provided. The data modulation method includes generating a channel sequence for an input sequence, determining whether or not the channel sequence violates a Run Length Limit (RLL) constraint, and performing, when the channel sequence violates the RLL constraint, bit flip at a position prior to a position at which the RLL constraint is violated among positions of bits included in the channel sequence. The data error correction method includes detecting an error bit of received data using a parity check matrix, determining whether or not the error bit is an error caused by bit flip, and correcting the error bit when the error bit is an error caused by bit flip for applying an RLL constraint.
摘要:
A method of constructing an effective generator polynomial for error correction by which a unique set of syndromes for each error event is produced is provided. The method includes preparing a set of dominant error events from the intersymbol interference characteristics of media; and generating a codeword from the data using a non-primitive generator polynomial that produces a unique syndrome set which can completely specify each dominant error event.
