본 발명은 일반사진기로 찍은 필름을 현상시킨 네가필름(네가티브필름)을 화상처리하여 모니터로 확대 재현시키고자 하는 네가 필름의 영사 방법에 관한 것이다. 사람의 눈은 영상 정보신호가 시간축으로 동일하게 인가되는 병렬 정보 신호(PARALLEL INFORMATION)로서 습득 인식하도록 되어 있으므로 텔레비젼을 제외한 영상 매체는 모두 그 영상신호가 병렬 정보 전달의 형태를 취하고 있으며 텔레비젼에는 텔레비젼용 카메라로써 병렬정보 신호(PI)를 직렬 정보신호(SERIAL INFORMATION) : (ST)로 변화시켜 영상 변조를 한 후 텔레비젼에서 다시 복조하여 브라운관의 형광면의 잔광 현상을 이용하여 병렬 정보신호로 재변환시키는 방법을 취하고 있는 것이다.The present invention relates to a projection method of a negative film which is intended to be enlarged and reproduced on a monitor by image processing a negative film (negative film) on which a film taken by a general camera is developed. The human eye is designed to recognize and recognize the video information signal as parallel information signal (PARALLEL INFORMATION), which is applied equally on the time axis. Therefore, all video media except television have the form of parallel information transmission. A parallel information signal (PI) is converted into a serial information signal (SERIAL INFORMATION) using a camera, and the image is modulated and then demodulated again on a television. Is taking.

그러나 일반 카메라로 촬영한 필름은 네가 필름이므로 포지티브 필름을 사용하는 환등기(SLIDE)에는 사용할 수 없기 때문에 네가필름을 영사시키고자 할때에는 텔레비젼과 같은 모니터로 출력시키는 영상 처리방법을 고려할 수가 있으나 병렬 정보신호를 직렬정보 신호로 변환시킬때에 네가필름의 영상신호에 따라서 광전변화시키기가 어려운 것이다. 본 발명의 목적은 일반적인 네가필름을 간단하게 광전 변환 후 확대시켜 간단히 모니터를 통하여 볼 수 있는 네가 필름의 영사방법을 제공하고자 하는 것으로 잔광시간이 짧은 형광물질을 브라운관의 형광막에 도포시키고 네가필름을 부착시켜 광증폭기와 색필터를 통하여 포토트랜지스터로 광전변화시킨 후 얻어진 상태 신호를 매트릭스회로와 영상 변조회로로 출력되게 한 것이며 다른 목적은 브라운관을 구동시키는 편향회로와 영상신호가 출력되는 비데오변조회로(9)의 동기신호를 일치시켜 안정된 영상을 얻고자 하는 것이다.However, since film taken with a general camera is negative film, it cannot be used for SLIDE using positive film. When you project negative film, you can consider an image processing method that outputs it to a monitor such as a TV. It is difficult to change the photoelectricity according to the image signal of the negative film when converting the signal into a serial information signal. It is an object of the present invention to provide a method of projecting a negative film that can be easily viewed through a monitor by simply expanding the general negative film after photoelectric conversion, and applying a fluorescent material having a short afterglow time to a fluorescent film of a CRT, After the photoelectric change through the optical amplifier and the color filter to the phototransistor, the obtained state signal is output to the matrix circuit and the image modulation circuit. This is to obtain stable image by matching synchronization signal of 9).

이를 첨부 도면에 의하여 상세히 설명하면 다음과 같다.This will be described in detail with reference to the accompanying drawings.

본 발명은 제1도와 같이 편향회로(6)의 제어신호에 따라 구동되는 브라운관(10)의 형광막(BR)에 잔상시간이 매우 짧은(0.05μS) 형광물질(ZnO : Zn은 조성물)로 도포시키고 이 형광막(BR)에 네가필름(1)를 밀착시킨 후 광중폭기(2)를 통하여 색필터 (3)(4)(5)에서 포토트랜지스터 (PT1)(PT2)(PT3)에 인가되게 구성시키어 도시되지 아니한 광차단막(11)으로 외부의 빛으로부터 차단되게 구성한다. 그리고 포토트랜지스터 (PT1)(PT2)(PT3) 저항(R1-R10), 콘덴서(C1-C3), 트랜지스터 (Q1)(Q2)(Q3)로 구성된 영상신호 출력부를 연결 구성시킨 후 매트릭스 회로(8)을 통하여 비데오 변조회로(9)에 인가되게 구성시킨 후 동기신호 발생회로(7)에서 편향회로(6) 및 비데오 변조회로(9)의 출력이 동기되게 연결 구성시킨 것이다.The present invention is coated with a fluorescent material (ZnO: Zn is a composition) having a very short afterimage time (0.05 µS) on the fluorescent film BR of the CRT 10 driven according to the control signal of the deflection circuit 6 as shown in FIG. After the negative film 1 is brought into close contact with the fluorescent film BR, the phototransistors PT 1 (PT 2 ) (PT 3 ) from the color filters 3, 4, and 5 are formed through the optical amplifier 2. It is configured to be applied to the light blocking film 11 not shown to block the external light. And a video signal composed of a phototransistor (PT 1 ) (PT 2 ) (PT 3 ) resistors (R 1 -R 10 ), capacitors (C 1 -C 3 ), and transistors (Q 1 ) (Q 2 ) (Q 3 ) After the output unit is connected and configured to be applied to the video modulation circuit 9 through the matrix circuit 8, the output of the deflection circuit 6 and the video modulation circuit 9 is synchronized in the synchronization signal generating circuit 7. The connection is configured.

제2도는 등기신호 발생회로와 비데오·변조회로의 실시예로서 동기신호 발생회로(7)는 발진기 (DS1)의 출력이 편향회로에 공급되는 동시에 지연 1회로(DE1)를 통하여 증폭기(A1)에 인가되게 한 것으로 지연 1회로(DE1)는 비데오 변조회로(9)에서 변조되는 시간과 일치하기 위하여 구성시킨 것이다.2 shows an embodiment of a registered signal generating circuit and a video / modulating circuit. In the synchronous signal generating circuit 7, the output of the oscillator DS 1 is supplied to the deflection circuit and at the same time, the amplifier A is supplied through the delay 1 circuit DE 1 . The delay 1 circuit DE 1 is configured to coincide with the time modulated by the video modulation circuit 9.

그리고 비데오 변조회로 (9)는 영상신호(R)(GB)의 출력이 지연 2회로(DE2)를 통하여 중폭기(A2)에 인가 되게 구성하고 타측으로 비교기(OP2)(OP1)에서 비교된 영상 상태신호가 저역통과 필터(PT1) (PT2)를 통하여 노이즈를 제거시킨 후 그중 평형 변조기 (F3)(F5)에 인가되게 하고 발진기 (OSC2)의 출력이 위상 반전회로(F1)에서 180°위상을 바꾸어 그중 평형 변조기(F4)와 위상 변한부(F4)에서 각각 위상을 변화시켜 변조되게 하여 각 영상신호에 따라 위상이 변하게 된다.The video modulation circuit 9 is configured such that the output of the image signal R (GB) is applied to the heavy amplifier A 2 through the delay 2 circuit DE 2 and to the other side of the comparator OP 2 (OP 1 ). The image state signal compared at is removed through the low pass filter (PT 1 ) (PT 2 ) and then applied to the balanced modulator (F 3 ) (F 5 ), and the output of oscillator (OSC 2 ) is inverted. In the circuit F 1 , the phases of the 180 ° are changed, and the phase modulator F 4 and the phase shifter F 4 are respectively changed in phase so that the phase is changed according to each image signal.

따라서 비데오 출력단자(IC4)의 복합 영상 신호의 출력은 비데오신호로 변조되어 출력되므로 병렬정보 신호가 직렬정보 신호로 출력되어 모니터에서 재병렬 정보신호로 변환시키므로 네가필름의 영상신호를 얻을 수가 있는 것이다.Therefore, since the output of the composite video signal of the video output terminal (IC 4 ) is modulated into a video signal and outputted, the parallel information signal is output as a serial information signal and converted into a reparallel information signal by a monitor, thereby obtaining a negative video signal. will be.

즉 본 발명은 편향회로 (6)의 출력이 브라운관 (10)에 인가되면 형광물질이 도포된 형광막(BR)에 발광된 빛이 네가필름(1)률 통하여 광증폭기(2)에서 증폭되어 색필터(3)(4)(5)에 인가되는 것으로 미세한 영상신호가 증폭되어 색필터를 통할때에 각 칼라 영상신호에 따라 포토트랜지스터(PT1)(PT2) (PT3)에 인가되는 상태신호가 각각 상이하게 된다.That is, in the present invention, when the output of the deflection circuit 6 is applied to the cathode ray tube 10, the light emitted from the fluorescent film BR coated with the fluorescent material is amplified by the optical amplifier 2 through the negative film 1 rate, and the color is changed. It is applied to the filters (3), (4), (5) and the fine image signal is amplified and applied to the phototransistor (PT 1 ) (PT 2 ) (PT 3 ) according to each color image signal when passing through the color filter. The signals are each different.

이 출력신호가 버퍼응 트랜지스터(Q1-Q3)를 통하여 매트릭스회로 (8)에 인가되면 칼라 영상신호인 적 (R),녹(G), 청(B)의 출력이 적당히 혼합된 Y신호, I신호, Q신호로서 3원색의 칼라 신호가 만들어지고 제2도와 같은 변조회로 (9)에서 영상 변조함으로써 네가필름의 영상이 복합비데오시그날로 변조시켜 모니터를 통하여 볼 수 있게 되는 것으로 동기신호 발생회로(7)의 동기신호에 따라 구동할 수가 있어 안정된 영상신호를 얻을수가 있는 것이다.When this output signal is applied to the matrix circuit 8 through the buffering transistors Q 1 -Q 3 , the Y signal in which the outputs of the red (R), green (G), and blue (B), which are color image signals, are properly mixed. Color signals of three primary colors are generated as I, Q and Q signals, and the image is modulated by the modulation circuit 9 as shown in FIG. 2 so that the image of the negative film is modulated into a composite video signal and viewed through a monitor. It can drive in accordance with the synchronization signal of the circuit 7, and can obtain a stable video signal.

이상에서와 같이 본 발명은 병렬 정보신호인 필름의 상을 브라운관의 광에 의한 스캔닝 처리하여 직렬 정보신호로 손쉽게 변환시킬수가 있는 것으로 사진기의 네가필름을 모니터로 통하여 일반 영상신호와 동일하게 볼수있는 효과가 있는 것이다.As described above, the present invention can easily convert the image of the film, which is a parallel information signal, into a serial information signal by scanning with the light of the CRT. It works.
