본 고안은 폐쇄회로 TV 감시장치에 관한 것이며, 특히 카메라 및 녹화부로부터 디스플레이로의 출력을 자유롭게 선택할 수 있는 폐쇄회로 TV 감시장치에 관한 것이다.The present invention relates to a closed circuit TV surveillance apparatus, and more particularly, to a closed circuit television surveillance apparatus capable of freely selecting an output from a camera and a recording unit to a display.
종래의 폐쇄회로 TV 감시장치에 의하면 카메라 신호입력 중 비디오의 시청(재생)을 하는 경우 카메라 입력단자를 뽑고, 비디오 입력단자를 꽂아야 하는 불편이 있었다.According to the conventional closed circuit TV monitoring apparatus, when watching (playing) a video during camera signal input, it is inconvenient to unplug the camera input terminal and plug in the video input terminal.
본 고안은 상기와 같은 문제점을 해결하기 위한 것으로 카메라로부터의 영상신호의 출력과 영상녹음기로부터의 재생된 영상신호의 출력을 간단한 스위치 조작에 의해 자유롭게 선택할 수 있는 폐쇄회로 TV 감시장치를 제공하기 위한 것이다.The present invention is to provide a closed circuit TV monitoring apparatus which can freely select the output of the video signal from the camera and the output of the reproduced video signal from the video recorder by a simple switch operation. .
상술한 목적의 달성을 위해 본고안은 피사체를 촬상하기 위한 카메라, 상기 카메라로부터 출력되는 영상신호를 저장하기 위한 녹화부, 상기 카메라로부터의 영상신호 및 녹화부로부터의 재생된 영상신호를 선택신호에 의해 선택하기 위한 멀티플렉서, 상기 선택신호를 선택스위치의 조작으로 제어하기 위한 제어부, 상기 멀티플렉서에 의해 선택된 영상신호를 출력하기 위한 디스플레이부를 포함한다.In order to achieve the above object, the present invention provides a camera for photographing a subject, a recording unit for storing image signals output from the camera, an image signal from the camera, and a reproduced image signal from the recording unit as a selection signal. And a control unit for controlling the selection signal by an operation of a selection switch, and a display unit for outputting a video signal selected by the multiplexer.
본고안의 상세한 설명 및 이에 따른 효과를 도면을 참조하여 설명한다.The detailed description of the present invention and the effects thereof will be described with reference to the drawings.
제1도는 본 고안에 관한 실시예를 나타내는 블록도이다.1 is a block diagram showing an embodiment according to the present invention.
제1도에서, 복수의 카메라(1)로부터의 영상신호(C1,C2)와 녹화부(2)로부터의 재생된 영상신호(C3)가 멀티플렉서(3)의 입력단자에 입력된다. 녹화부(2)는 복수의 카메라(1)로부터 멀티플렉서(3)에 전달된 영상신호(C1,C2)를 그대로 녹화하거나 선택적으로 녹화할 수 있다. 멀티플렉서(3)에 입력된 영상신호(C1,C2,C3)는 제어부(5)에 의해 발생되는 선택신호(S1,S2)에 의해 제어되어 한 개의 영상신호만이 디스플레이(4)로 출력된다. 선택신호(S1,S2)의 논리값은 각각 영상신호(C1,C2,C3)의 선택 및 자동(AUTO)모드의 선택에 대응된다. 여기서 자동(AUTO)모드는 카메라(1)로부터의 영상신호(C1,C2)를 일정시간 주기로, 예컨데 30초를 주기로 교대로 대스플레이(4)로 출력하도록 하는 모드이다.In FIG. 1, the video signals C1 and C2 from the plurality of cameras 1 and the reproduced video signal C3 from the recording unit 2 are input to the input terminal of the multiplexer 3. The recording unit 2 may record or selectively record video signals C1 and C2 transmitted from the plurality of cameras 1 to the multiplexer 3. The video signals C1, C2 and C3 input to the multiplexer 3 are controlled by the selection signals S1 and S2 generated by the controller 5 so that only one video signal is output to the display 4. The logic values of the selection signals S1 and S2 correspond to the selection of the video signals C1, C2 and C3 and the selection of the AUTO mode, respectively. The AUTO mode is a mode for outputting the video signals C1 and C2 from the camera 1 to the large display 4 alternately at regular time intervals, for example, at 30 seconds.
사용자는 선택스위치(C'1,C'2,C'3,A)를 간단히 조작하여 이에 대응하는 선택신호를 생성시킴으로써, 상기의 모드 중 필요한 모드를 선택할 수 있다. 예컨데 C'1 스위치를 선택하면 선택신호 S1,S2는 각각 로우값으로 되어 C1의 영상신호를 선택하고, C'2스위치를 선택하면 S1,S2는 각각 로우, 하이값으로 되어 C2의 영상신호를 선택한다. 마찬가지로 C'3 스위치는 재생된 영상신호(C3)를 선택하고 A 스위치는 자동 모드를 선택한다.The user can select a required mode among the above modes by simply operating the selection switches C'1, C'2, C'3 and A and generating a selection signal corresponding thereto. For example, if the C'1 switch is selected, the selection signals S1 and S2 become low values, respectively, and the video signal of C1 is selected. If the C'2 switch is selected, the S1 and S2 become low and high values, respectively, and the C2 video signal is selected. Choose. Similarly, the C'3 switch selects the reproduced video signal C3 and the A switch selects the automatic mode.
제2도는 본 고안의 설명을 위한 플로챠트이다.2 is a flowchart for explaining the present invention.
먼저, 선택스위치가 자동모드(A)인지 여부를 판단한다.(제1단계) 만일 자동모드(A)라고 하면 카메라(1)로부터의 영상신호(C1,C2)를 일정시간 주기로 교대로 디스플레이(4)로 출력한다. 한편, 자동(A)모드가 아니라고 판단하는 경우 C3' 선택스위치가 선택되었는지 여부를 먼저 판단한다.(제2단계) 여기서, 만일 C3' 스위치가 선택되지 않은 경우는 C1', 또는 C2'스위치 중의 하나가 선택된 것이므로 각각의 스위치 선택에 따른 각각의 영상신호(C1,C2)를 디스플레이로 출력한다. 또한, C'1,C'2 스위치가 모두 선택되지 않은 경우에는 C1영상신호를 디스플레이로 출력하도록 구성해도 좋다.First, it is determined whether the selection switch is in the automatic mode A. (First step) If the automatic mode A is selected, the image signals C1 and C2 from the camera 1 are alternately displayed at regular time intervals ( Output to 4). On the other hand, if it is determined that it is not in the automatic (A) mode, it is first determined whether the C3 'selection switch is selected. (Second step) Here, if the C3' switch is not selected, the C1 'or C2' switch is selected. Since one is selected, each video signal C1 or C2 according to each switch selection is output to the display. When neither the C'1 or C'2 switch is selected, the C1 video signal may be output to the display.
한편, 제2단계에서, C3'스위치가 선택된 경우는 재생된 영상신호(C3)를 디스플레이(4)로 출력한다. 그러나, 영상신호의 재생 중에도 카메라로부터의 영상신호(C1,C2)를 보고자하는 경우가 있으므로 이 경우에는 C1' 또는 C2'스위치를 선택함(단계3)으로써 재생 중에도 카메라로부터의 영상신호(C1,C2)를 볼 수 있다. 다만, 재생 중 카메라로부터의 영상신호(C1,C2)를 보는 것은 C'1 또는 C'2스위치를 선택하고 있는 동안에만 가능한 것이며, C'1 또는 C'2 스위치 선택의 취소 후에는 다시 재생영상 신호만을 볼 수 있다.In the second step, when the C3 'switch is selected, the reproduced video signal C3 is output to the display 4. However, there are cases where the video signals C1 and C2 from the camera are to be viewed even during the playback of the video signals. In this case, the video signals C1 and C1, from the camera are also reproduced by selecting the C1 'or C2' switch (step 3). C2) can be seen. However, viewing the video signal (C1, C2) from the camera during playback is possible only while the C'1 or C'2 switch is selected, and the playback image is replayed after the C'1 or C'2 switch is cancelled. You can only see the signal.
본 고안의 실시예에서는 2대의 카메라와 1대의 디스플레이로 설명하였으나, 이에 한정되는 것이 아니라 복수의 카메라를 2대 이상의 디스플레이로 구성하여도 좋다. 이 경우 복수의 카메라로부터의 영상을 여러장소에서 보는 것이 가능하며, 또한, 각각의 장소에서도 선택스위치를 조작함으로써 재생 중에도 카메라로부터의 영상을 직접 볼 수 있다.In the embodiment of the present invention, two cameras and one display have been described, but the present invention is not limited thereto, and a plurality of cameras may be configured with two or more displays. In this case, the images from a plurality of cameras can be viewed at various places, and the images from the cameras can be viewed directly during playback by operating the selector switch at each place.
이상에서 살펴본 바와 같이, 본 고안은 상기와 같은 구성을 취함으로써 복수의 카메라로부터의 영상신호를 하나 이상의 디스플레이로 출력할 수 있으며, 또한, 재생된 영상을 보고 있는 경우에도 간단한 스위치 조작으로 카메라로부터의 영상을 직접 볼 수 있다.As described above, the present invention can output video signals from a plurality of cameras to one or more displays by taking the above-described configuration. Also, even when viewing a reproduced video, the present invention can be operated by a simple switch operation. You can see the video directly.
