본 고안은 티브이의 화질개선을 위해 콤 필터(Comb Filter)를 내장한 칼라티브이에 있어서 필연적으로 부수되는 DC레벨보상문제를 콤필터 자체내에서 해결한 개량형 콤 필터에 대한 것이다.The present invention is an improved comb filter that solves the DC level compensation problem inevitably in the comb filter itself, which is inevitably accompanied by a comb filter with a built-in comb filter.
칼라티브이에 있어서 화질을 고급화시키고 해상도를 높이기 위하여 종래부터 콤필터를 사용하여 왔으나, 이 콤 필터를 사용할 경우는 필연적으로 DC레벨보상문제를 해결해 주어야 하며 이를 위해 별도의 DC레벨보상회로를 설치해야 하므로 콤 필터회로를 구성하는 전체 부품수가 증가하게 되어 이 부분의 기술적 처리가 어려워 지는 단점이 있었다. 즉, 티브이 회로에 있어서, 가장 예민하게 외부영향을 받기쉬운 부분이 이 콤 필터회로로서 일반적으로 차폐물(Shield)등으로 보호하여 사용되고 있는데, 이 콤 필터 회로부분의 구성부품수를 감소시킬 수록 기술적 처리가 유리해지게 된다.Since the comb filter has been conventionally used to improve the image quality and the resolution in the colorimetric, however, when the comb filter is used, the DC level compensation problem is inevitably solved, and a separate DC level compensation circuit must be installed for this purpose. As the total number of parts constituting the comb filter circuit increases, technical processing of this part becomes difficult. In other words, in the TV circuit, the most sensitive parts that are susceptible to external influence are generally used as shields, etc., as the comb filter circuits. Is advantageous.
본 고안은 이와같은 점에 착안하여 콤필터 자체에서 DC레벨 보상문제를 해결한 것으로, 별도의 DC레벨 보상회로를 필요로 하지 않고 상대적으로 콤 필터회로의 전체 부품수를 감소시킴으로써 이 부분의 기술적 처리를 용이하게 하는 한편, 생산원가를 절감시키기 위함에 고안의 목적이 있는 바, 이를 첨부도면에 의해 상술하면 다음과 같다.The present invention solves the DC level compensation problem in the comb filter itself by focusing on such a point, and does not require a separate DC level compensation circuit, and relatively reduces the total number of parts of the comb filter circuit so that the technical processing of this part is possible. On the other hand, the purpose of devising to reduce the production cost, which is described in detail by the accompanying drawings as follows.
제1도는 콤 필터(C)와 DC레벨보상회로(D)가 결합된 종래의 콤 필터 회로도로서, 단자(1)로 입력된 영상신호가 커플링 콘덴서(C1)(C2)를 통하여 DC레벨전압이 제거된후 표면파와의 콤빙에 의해 색실호와 명도신호로 분리된다. 여기에서 색신호는 트랜지스터(Q1)(Q2)를 통해 단자(2)로 출력되며, 명도신호는 트랜지스터(Q3)(Q4)를 통한후, 단자(4)로 입력되는 수직펄스전압에 의해 동작하는 DC레벨 조정용 IC(DI)등으로 구성된 DC레벨보상회로(D)를 거쳐서 단자(3)로 출력된다.FIG. 1 is a conventional comb filter circuit diagram in which a comb filter C and a DC level compensating circuit D are combined, and an image signal input to the terminal 1 is connected to a DC level voltage through a coupling capacitor C1 and C2. After this is removed, it is separated into color signals and brightness signals by combing with surface waves. Here, the color signal is outputted to the terminal 2 through the transistors Q1 and Q2, and the brightness signal is driven by the vertical pulse voltage input to the terminal 4 after the transistors Q3 and Q4. It is output to the terminal 3 via the DC level compensating circuit D composed of a level adjusting IC (DI) or the like.
이에대하여 제2도는 본 고안의 회로도로서, 콤 필터 및 DC레벨 보상회로로 구성된 종래의 콤 필터회로에 있어서 커플링 콘덴서(C2)를 제거하므로써 단자(1)로 입력된 영상신호를 영상신호 내에 포함된 DC레벨전압이 원상인 채로 저항(R5)만을 통해 각 트랜지스터(Q1)(Q3)의 에미터에 연결되도록하고, 트랜지스터(Q4)의 에미터로 출력되는 명도 신호를 별도의 DC레벨보상 회로를 거치지 않고 직접 명도신호 출력 단자(3)에 연결한 것으로, 미설명부호 2는 색신호 출력단자, C1은 커플링 콘덴서, Q2는 트랜지스터, R1~R6는 저항을 나타낸다.2 is a circuit diagram of the present invention. In the conventional comb filter circuit composed of a comb filter and a DC level compensating circuit, the video signal input to the terminal 1 is included in the video signal by removing the coupling capacitor C2. The connected DC level voltage is connected to the emitters of the transistors Q1 and Q3 only through the resistor R5, and the brightness signal outputted to the emitter of the transistor Q4 is connected to a separate DC level compensation circuit. Directly connected to the brightness signal output terminal 3 without reference, reference numeral 2 denotes a color signal output terminal, C1 denotes a coupling capacitor, Q2 denotes a transistor, and R1 to R6 denote resistances.
종래의 칼라티브이에 있어서 화질의 고급화를 위해 3.58MHz주변대역에 형성되는 색신호영역내의 명도 신호를 취출하는 목적으로 제1도와 같은 콤 필터회로가 사용되어 있으나, 이는 콤 필터(C)로 입력된 영상신호를 표면파와의 콤빙에 의해 색신호와 명도신호로 분리하여야 하므로 영상신호내에 포함된 DC레벨전압을 각각 커플링 콘덴서(C1)(C2)를 통해 제거시켜야 했다. 또한 트랜지스터(Q4)의 에미터로 출력되는 명도신호가 입력영상신호의 크기에 따라 DC레벨기준이 변동되므로 정상적인 화상을 얻을 수 없으며, 따라서 필연적으로 별도의 DC레벨보상회로(D)를 구성하여서 DC레벨분을 보상받도록 되어있다. 이러한 이유로 종래의 회로에 있어서는 콤 필터회로의 전체구성 부품수가 증가되어 비 경제적임은 물론 이 부분의 기술적 처리가 곤란해지는 문제점이 있었던 것이다. 그러나 본 고안에 있어서는, 단자(1)로 입력된 영상신호가 커플링 콘덴서(C1)를 통해 DC레벨전압이 제거된 후 표면파와의 콤빙에 의해 색신호 및 명도신호로 분리되고, 색신호는 트랜지스터(Q1)(Q2)에 의해 단자(2)로 출력되며 각 트랜지스터(Q1)(Q3)사이의 궤환회로에 의해 색신호 및 명도신호의 분리도를 높여주는 회로는 공지와 같으나, 입력된 영상신호의 일부를 트랜지스터(Q1)(Q3)의 각 에미터로 공급함에 있어서 커플링 콘덴서(C2)를 제거한 저항(R5)만에 의해 영상신호내에 포함된 DC레벨전압도 원상 그대로 공급하게 되므로 단자(3)로 출력되는 명도신호에대해 종래와 같은 복잡한 별도의 DC레벨보상회로(D)의 구성을 필요로 하지 않게 되었다. 따라서 전체적인 구성부품수가 감소함은 물론 이 부분의 기술적 처리가 용이하게 되는 것이다.In the conventional color shift, the comb filter circuit as shown in FIG. 1 is used to extract the brightness signal in the color signal region formed in the 3.58 MHz peripheral band for the enhancement of the image quality. Since the signal must be separated into the color signal and the brightness signal by combing with the surface wave, the DC level voltage included in the image signal must be removed through the coupling capacitors C1 and C2, respectively. In addition, since the DC level reference varies according to the magnitude of the input image signal, the brightness signal output to the emitter of transistor Q4 cannot obtain a normal image. Therefore, a separate DC level compensation circuit (D) is inevitably formed. The level is to be rewarded. For this reason, in the conventional circuit, the total number of components of the comb filter circuit is increased, which is not economical, and the technical processing of this part is difficult. However, in the present invention, the video signal inputted to the terminal 1 is separated into a color signal and a brightness signal by combing with a surface wave after the DC level voltage is removed through the coupling capacitor C1, and the color signal is transistor Q1. The circuit which outputs to the terminal 2 by Q2 and improves the separation of the color signal and the brightness signal by the feedback circuit between the transistors Q1 and Q3 is the same as the known one, but a part of the input image signal is a transistor. When supplying to each emitter of (Q1) and (Q3), the DC level voltage included in the video signal is also supplied as it is by the resistor R5 from which the coupling capacitor C2 is removed. With respect to the brightness signal, it is no longer necessary to construct a separate complicated DC level compensation circuit D as in the prior art. Therefore, the overall number of components is reduced, as well as the technical processing of this part is easy.
한편, 커플링 콘덴서(C2)를 제거시키므로서 영상신호내의 DC레벨전압도 각 트랜지스터(Q1)(Q3)에 공급되기 때문에, 각각의 트랜지스터(Q1~Q4)의 바이어스 전위를 적당히 조절해 주어야 하는바, 이는 저항(R2~R6)을 조정해 주고, 또한 단자(3)로 출력되는 명도신호의 출력 파형특성을 높여주기위해 저항(R5)(R6)을 조정해 주므로써 커플링콘덴서(C2)가 없어도 아무런 문제가 초래되지 않는 것이다.On the other hand, since the DC level voltage in the video signal is also supplied to each of the transistors Q1 and Q3 by removing the coupling capacitor C2, the bias potential of each of the transistors Q1 to Q4 must be adjusted appropriately. This adjusts the resistors R2 to R6, and adjusts the resistors R5 and R6 to increase the output waveform characteristics of the brightness signal output to the terminal 3, thereby coupling the capacitor C2. Without it, no problem is caused.
이상과 같이, 본 고안은 칼라티브이에 있어서 화질의 고급화를 위해 콤 필터를 사용하는 경우 필연적으로 부수되는 DC레벨보상문제를 콤 필터자체내에서 간단히 해결해 주므로써, 전체 구성 부품의 수가 감소됨은 물론 회로적으로 예민한 콤 필터 회로부분의 기술적 처리문제를 용이하게 한 유용한 고안인 것이다.As described above, the present invention simply solves the inevitable DC level compensation problem in the comb filter itself when using the comb filter to improve the quality of the color in the comb filter itself. It is a useful design that facilitates the technical processing problem of the sensitive comb filter circuit part.
