Abstract

이 발명은 캠코더에 관한 것으로, 화면 분할부(10)를 이용하여 화면을 6분할하고 디지탈 적분부(20)를 이용하여 분할된 각 영역의 데이타에 대한 평가치를 산출하여 슈퍼임포징부(30)에 입력시켜 마이콤(MICOM)으로부터의 데이타와 슈퍼임포징함으로써 타이틀 부분이 다색으로 표현되게 하므로 타이틀의 부각성을 높이며 슈퍼임포징의 기능을 향상시킨 것이다.The present invention relates to a camcorder, wherein the screen is divided into six parts using the screen dividing unit 10 and the superimposing unit 30 calculates an evaluation value for data of each divided region using the digital integrating unit 20. The title part is expressed in multiple colors by superimposing the data from MICOM and inputting the data into the multi-color, thereby increasing the prominence of the title and improving the superimposition function.
