摘要： Disclosed is a united microphone with a camera using free focus lens, comprising a microphone for converting audio signal into electric signal; a CCD camera united with the microphone, for converting video signal into electric signal; and a free focus lens lays for clearly forming an image of a short distance and a long-distance subject on a CCD chip of the CCD camera. It is possible to take a clear image at a short distance using the free focus lens and also to output the image with the sound. Further, the united microphone with a camera according to the present invention can be connected to a recording device like a video recorder.
摘要翻译：公开了具有使用自由聚焦透镜的照相机的联合麦克风，包括用于将音频信号转换为电信号的麦克风; 一个CCD摄像机与麦克风相结合，用于将视频信号转换为电信号; 并且自由对焦镜头用于在CCD照相机的CCD芯片上清楚地形成短距离和长距离物体的图像。可以使用自由对焦镜头在短距离拍摄清晰的图像，并且还可以用声音输出图像。此外，根据本发明的具有相机的联合麦克风可以连接到诸如录像机的记录装置。
