Abstract
본 발명은 비디오 카메라에 관한 것으로, 특히 소음 환경에서의 영상회이나 다화자간의 영상회의에서 음성 정보의 수집이 용이하도록 한 비디오 카메라 장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to video cameras, and more particularly, to a video camera apparatus for facilitating collection of audio information in video conferencing in a noisy environment or video conferencing between talkers.
이러한 본 발명은 피사체의 음성신호를 입력 받기 위한 복수개의 마이크로 폰으로 이루어진 음성입력수단과, 조리개에 의해 피사체에 촛점이 맞추어지면 상기 음성입력수단내의 각 마이크로 폰과 피사체와의 거리를 계산하는 거리계산수단과, 상기 거리계산수단에서 얻어지는 각 마이크로 폰의 거리값에 따라 지연시간을 계산하여 각 마이크로 폰의 가증치를 부여하는 지연제어수단과, 상기 지연제어수단에서 출력되는 각 마이크로 폰의 가증치에 따라 복수개의 마이크로 폰으로 부터 입력되는 음성신호를 각각 필터링 하는 적응필터링수단과, 상기 적응필터링 수단내의 복수개의 필터로 부터 각각 출력되는 음성신호를 가산하여 녹음용 음성신호로 출력하는 가산수단으로 이루어진다.The present invention is a voice input means consisting of a plurality of microphones for receiving a voice signal of the subject, and the distance calculation for calculating the distance between the microphone and the subject in the voice input means when the focus is on the subject by the aperture A delay control means for calculating a delay time according to the distance value of each microphone obtained by the distance calculating means and giving an increment value for each microphone, and according to the increment value of each microphone output from the delay control means. Adaptive filtering means for filtering the voice signals input from the plurality of microphones, respectively, and adding means for adding the audio signals respectively output from the plurality of filters in the adaptive filtering means and outputting them as recording voice signals.
