Abstract

본 발명은 캠코더 촬영시 마이크 신호에 음악을 별도로 삽입하여 촬영과 동시에 더빙(dubbing)을 수행하므로서 음향효과를 향상시키는데 적당한 캠코더의 배경효과음 동시 더빙장치와 방법에 관한 것으로, 좌,우측 마이크(1)(2)를 통해 입력된 음성신호만을 테이프에 기록하므로 사용자가 음향효과를 얻고자하면, 편집기를 사용하여 별도의 배경음악(음향)을 더비하여야 하기 때문에 불편함이 따르는 문제점을 해결하기 위한 것이다.The present invention relates to an apparatus and a method for simultaneously dubbing a background effect sound of a camcorder suitable for enhancing sound effects by separately inserting music into a microphone signal during dubbing and performing dubbing at the same time. Since only the audio signal input through (2) is recorded on the tape, the user is to solve the problem of inconvenience caused by having to add a separate background music (sound) by using an editor.

본 발명은 이와같은 종래 문제점을 해결하기 위하여 다양한 내용의 음악, 음향, 음성을 메모리에 저장하고 캠코더 촬영중 필요시 메모리에 저장된 음악, 음향, 음성신호를 삽입하여 촬영과 동시에 더빙이 가능하게 하므로서 편집에 편리를 기하고 음향효과를 향상시키도록 한 것으로, 캠코더에 적용한다.In order to solve the conventional problem, the present invention stores various contents of music, sound, and voice in a memory, and inserts music, sound, and voice signals stored in the memory when necessary during camcorder shooting, thereby enabling dubbing at the same time as recording. It is designed to enhance the sound effects and to make it convenient for the camcorder.
