摘要： Provided are an apparatus and method for precisely processing an input signal by detecting the frequency characteristic of the signal and applying the detection result in an image signal processing block to reduce noise in the signal or enhance the details of the signal. The apparatus includes an indication value calculator, a level selector, and a frequency characteristic determination unit. Accordingly, the frequency distribution of an input signal is analyzed, and the signal is filtered by adjusting its filtering frequency band based on the analyzed frequency characteristic. Thus, it is possible to appropriately filter a signal using only a filter regardless of the resolution of the signal. In particular, noise in the signals of different scale ratios can be reduced or the details of the signal can be enhanced by processing the signals by only a filter.

摘要： A display apparatus having a display part to receive a predetermined weight number of sustain pulses to display a frame of an image time-shared into a plurality of subfields, the display apparatus includes a motion detector to determine whether an input image is a still image, and a pulse driver to transmit a number of sustain pulses to the display part, and to decrease the number of sustain pulses transmitted to the display part to cause every frame to be smaller than the weight number when the motion detector determines the input image to be the still image. In this display apparatus and control method thereof, image sticking is prevented without deteriorating gradation representation and without a visual error.

摘要： A high-definition image display device and a method of converting a frame rate thereof are provided. The high-definition image display device includes an image processing unit which processes an input image signal, a first frame rate conversion (FRC) unit which receives an image signal from the image processing unit and generates first interpolated data by processing a first part of frame data of the image signal, and a second FRC unit which generates second interpolated data by processing a second part of the frame data of the image signal and outputs the second interpolated data to the first FRC unit, wherein the first and second interpolated data are combined by and output from the first FRC unit. Accordingly, clear pictures can be provided by converting the frame rate through processing of large capacity data according to the high resolution of the image display device, using a plurality of FRC circuits.
