Description

네가 티브 필름의 영상 확대방법How to magnify a negative film

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제1도는 본 발명의 회로도. 제2도는 본 발명의 수광부에서 사용하는 포토다이오드의 전류 및 전압 특성도.1 is a circuit diagram of the present invention. 2 is a current and voltage characteristic diagram of a photodiode used in the light receiving unit of the present invention.

가 : 신호발생회로, 3 : 음극선관, 4 : 네가티브 필름, 5 : 수광부, 6 : 앰프, 7 : 동기신호 발생부, 8 : 엔코더, 9 : RF 모듈, 10 : 모니터.A: signal generating circuit, 3 cathode ray tube, 4 negative film, 5 light receiving unit, 6 amplifier, 7 synchronization signal generator, 8 encoder, 9 RF module, 10 monitor.

Claims (1)

네가티브 필름(4)을 음극선관(3) 앞에 밀착하여 동기 신호 발생부(7)의 동기 신호에 따라 통상의 신호발생회로(가)가 구동되어서 네가티브 필름(4)의 영상 신호를 직렬 전송이 되게 구성하고 이 전송된 상태신호를 수광부(5)에서 수신한 앰프(6)에서 증폭된 후 동기 신호 발생부(7)의 동기 신호가 인가된 엔코더(8)에서 모니터(10)로 영상 신호가 발생하도록 한 네가티브 필름의 영상 확대방법.The negative film 4 is brought into close contact with the cathode ray tube 3 so that a normal signal generation circuit A is driven in accordance with the synchronization signal of the synchronization signal generator 7 so that the image signal of the negative film 4 is serially transmitted. After amplifying the transmitted state signal by the amplifier 6 received by the light receiving unit 5, an image signal is generated from the encoder 8 to which the synchronization signal of the synchronization signal generator 7 is applied to the monitor 10.
