Abstract: A method for controlling a video encoding data rate is provided to control video encoding data rate for an image having much motion in an environment of low bit rate and high frame rate, thereby having stable and improved performance despite the bad environment. A target bit of the current frame is estimated(332). If the estimated target bit is a negative number, it is determined whether image complexity is high(352). If the image complexity is high in the determined result, a previous quantization parameter is increased to a first value preset(354). If the image complexity is low in the determined result, the previous quantization parameter is increased to a second value preset(356).

Abstract: A realtime scene-change detecting method for the control of a video encoding data rate is provided to reduce hardware complexity and detect a change of a scene more efficiently. A realtime scene-change detecting method comprises the following steps of: predicting the PSNR(Peak Signal to Noise Ratio) of a current frame by using intersample error information between the current frame and a previous frame(304); determining whether the predicted PSNR is deviated from a preset reference value(308); and considering scene-change performed in the current frame when the predicted PSNR is deviated from the preset reference value(310).

Abstract: An intermediate image producing method and a 3D display device therefor are provided to prevent flickering resulting in the change of a brightness value of a motion picture for a still object by using a previous transition vector estimated for pixels having no motion by a previous frame when producing an intermediate image from images input from at least two cameras. An intermediate image producing method includes the steps of adding pixel value differences between first and third frames per block and adding the same together(S901), and comparing the sum with a first threshold value(S903). A first center pixel of a block, of which a sum of the pixel value differences is higher than the first threshold value, is determined as a pixel having motion. A second center pixel of a block, of which a sum of the pixel value differences is lower than the first threshold value, is determined as a pixel having no motion. A current disparity vector corresponding to a motion vector between the first frame and a second frame is calculated and a previous disparity vector corresponding to a motion vector between the third frame and a fourth frame is calculated. An intermediate image is generated based on the current disparity vector for the pixel having motion, and based on the previous disparity vector for the pixels having no motion(S909,S911).

Abstract: PURPOSE: An OFDM-based synchronization detector and a detecting method thereof are provided to utilize a shifter instead of a multiplier and reduce the complexity by using a correlator to quantize a correlation coefficient by a 2¬n level. CONSTITUTION: An OFDM-based synchronization detector includes registers(211-213) of m number, shifters(321-325) of m number, an adder(330), and a peak value detector(340). The registers(211-213) are used for storing received data. The shifters(321-325) are used for shifting each output of the registers as much as an exponent of a correlation coefficient which is quantized by a 2¬n level. The adder(330) is used for adding each output of the shifters, sequentially. The peak value detector(340) is used for detecting peak values from the outputs of the adder.
