Abstract: An apparatus and method for controlling the audio noise attenuation by monitoring a buffer are disclosed. If the audio data to be reproduced, and if the user sets the operation as an automatic mode so that the operation of controlling the audio noise attenuation by monitoring the buffer is automatically executed, the operation of the loudspeaker is interrupted. In addition, if the audio data to be reproduced is stored, the loudspeaker is continuously driven regardless of the set of the mode. Furthermore, if there is no the audio data to be reproduced, and if the operation is not set as the automatic mode, the loudspeaker is operated. Accordingly, the analog noise, which may be generated when silence is outputted from the loudspeaker, can be eliminated, thereby improving the quality of the conference and the audio reproducing quality.
Abstract translation: 公开了一种通过监视缓冲器来控制音频噪声衰减的设备和方法。 如果要再现的音频数据，并且如果用户将操作设置为自动模式，从而自动执行通过监视缓冲器来控制音频噪声衰减的操作，则扬声器的操作被中断。 另外，如果要再现的音频数据被存储，则不管模式的设置如何，扬声器都被连续驱动。 此外，如果没有要再现的音频数据，并且如果该操作未被设置为自动模式，则操作扬声器。 因此，可以消除从扬声器输出无声时可能产生的模拟噪声，从而提高会议质量和音频再现质量。

Abstract: PURPOSE: A method for detecting a face area using an SVM(Support Vector Machine) is provided to prevent a wrong face detection and reliably detect a face in real-time by searching candidates of an eye pair from an image and precisely detecting the face area through an SVM verifier after detecting the candidate areas of the face based on the candidate of the eye pair. CONSTITUTION: The candidates of the eye pair are searched by using the brightness information of the inputted image(300). The inclination correction for the image is performed based on a center of the detected candidates and the candidate face areas are regulated(400). The face area of the highest probable candidate face area is detected by verifying the regulated candidate face areas through the previously learned SVM verifier(800).

Abstract: PURPOSE: An adaptive feedforward linear amplifier is provided to automatically and adaptively eliminate a cross modulation signal generated in an extremely high frequency element having a nonlinear feature at real time. CONSTITUTION: A main amplifier(500) adjusts an intensity and a phase of an input signal to amplify it. An input circuit(510) couples a signal in a process which provides a signal inputted to a circuit to the main amplifier(500). An error amplifier(520) combines an output signal of the input circuit(510) with a signal of the main amplifier(500), extracts a cross modulation signal generated in the main amplifier(500), and amplifies the extracted cross modulation signal to desired intensity and phase. A signal generator(530) generates a pilot signal in a frequency band other than an operation frequency band. A controller(540) adjusts the signal generator(530) using a signal detector(544) of an input of the circuit and a signal detector(549) of an output of the circuit. The controller(540) controls a variable intensity attenuator and a variable phase convert.
