Abstract
본 발명은 흑백 및 칼라 신호의 기록 장치에 관한 것으로서, 특히 흑백 모드의 기록시 휘도 성분을 더 기록하여 고 해상도의 흑백 신호를 기록할 수 있는 흑백 기록 장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a black and white and color signal recording apparatus, and more particularly, to a black and white recording apparatus capable of recording a high resolution black and white signal by further recording a luminance component during black and white mode recording.
본 발명의 목적을 위하여 칼라 기록 모드시 아날로그-디지탈 변환부에서 발생하는 칼라 신호 성분을 대역 압축하고, 흑백 기록 모드시 칼라 신호 성분을 소정의 레벨 값으로 변환하는 칼라 신호 처리부, 칼라 기록모드시 아날로그-디지탈 변환부에서 발생하는 휘도 신호 성분과 칼라 신호 처리부의 대역 압축된 칼라 신호성분을 데이타 압축 처리하고, 흑백 기록 모드시 아날로그-디지탈 변환부에서 발생하는 휘도 신호 성분과 칼라 신호 처리부의 소정의 레벨 값으로 변환된 칼라 신호 성분 영역에 휘도 신호 성분이 가해진 신호를 데이타압축 처리하는 데이타 신호 처리부, 칼라 기록 모드 및 흑백 기록 모드 선택 신호를 발생하는 제어부, 데이타 신로 처리부에서 발생하는 압축 비디오 데이타를 기록하는 기록부를 포함하는 것을 특징으로 한다.For the purpose of the present invention, a color signal processor for band-compressing the color signal components generated in the analog-digital conversion unit in the color recording mode, and converting the color signal components to a predetermined level value in the black-and-white recording mode, analog in the color recording mode. Data compression processing of the luminance signal component generated by the digital converter and the band-compressed color signal component of the color signal processor, and the predetermined level of the luminance signal component and the color signal processor generated by the analog-digital converter in the black and white recording mode. A data signal processor for data compression processing a signal to which a luminance signal component is applied to a color signal component region converted to a value, a controller for generating a color recording mode and a black and white recording mode selection signal, and for recording compressed video data generated by a data channel processor And a recording unit.
본 발명에 의하면, 비디오 신호 기록시 흑백 모드로 할 경우 칼라 신호 성부 대신에 휘도 신호 성분을 추가함으로서 해상도가 더 높은 흑백 신호 기록이 가능한 잇점이 있다.According to the present invention, when the black and white mode is used when recording a video signal, a black and white signal recording having a higher resolution can be performed by adding a luminance signal component instead of the color signal.
