[ A key matrix 12 for selecting a video recording and reproducing function, a key matrix 12 for selecting a video recording and reproducing function, 12 to receive and record a video signal A deck unit 14 for recording a video signal or reproducing a signal recorded on the tape by a control signal outputted from the microcomputer 13, A luminance / color generating unit 15 that receives the luminance signal and the color signal output from the DSP unit 11 by a signal and outputs a composite video signal, and a luminance / And an fsc portion 16 for applying an NTSC subcarrier frequency (3.58 MHZ)

이와 같이 구성된 종래 캠코더는 도 1에 도시된 바와 같이, 먼저, 렌즈(1)에서 촬영된 피사체가 CCD부(2)를 통해 광전변환되어 CDS/AGC부(3)에 인가되면 상기 CDS/AGC부(3)는 CCD부(2)에서 출력된 신호를 입력받아 신호가 있는 부분과 노이즈부분을 각각 샘플링한후 순수한 신호만을 자동이득조절하여 출력하므로서 A/D변환부(4)는 CDS/AGC부(3)에서 자동이득조절출력된 디지탈신호를 아날로그신호로 변환하여 DSP부(11)에 인가한다.1, when the subject photographed by the lens 1 is photoelectrically converted through the CCD unit 2 and applied to the CDS / AGC unit 3, the CDS / AGC unit 3, The A / D converter 4 receives the signal output from the CCD unit 2, samples the portion having the signal and the noise portion, and outputs only the pure signal with automatic gain control. The A / (3) converts the digital signal output from the automatic gain control unit into an analog signal and applies it to the DSP unit (11).

이때 타이밍발생부(8)와 동기신호발생부(9)는 메인클럭발진부(7)와 팔 4fsc PLL부(10) 및 카메라마이컴(6)에 의하여 카메라 신호처리가 팔방식일 경우 메인클럭발진부(7)에서는 28.375MHZ의 크리스탈 발진을 하게 되고 팔 4fsc PLL부(10)에서는 17,734MHZ의 PLL에 의해 상기 메인클럭발진부(7)에서 출력된 28.375MHZ 와 위상을 보정하게 된다.At this time, the timing generator 8 and the synchronization signal generator 9 are controlled by the main clock oscillator 7, the 4fsc PLL unit 10, and the camera microcomputer 6, 7, the crystal oscillation of 28.375 MHz is performed. In the arm 4 fsc PLL unit 10, the PLL of 17,734 MHz is used to correct the phase of 28.375 MHz output from the main clock oscillation unit 7.

따라서, 팔방식의 경우 컬러서브캐리어주파수는 4.43MHZ로 링변조하게 되어 컬러신호를 생성하게 되고 수직동기 주파수는 50HZ로 동작을 하게 되므로서 DSP부 (11)는 휘도신호와 컬러신호를 VCR부의 휘도/컬러발생부(15)에 인가하게 된다.Therefore, in the case of the arm system, the color subcarrier frequency is ring-modulated to 4.43 MHz to generate a color signal and the vertical synchronizing frequency operates at 50 Hz, so that the DSP unit 11 converts the luminance signal and the color signal into luminance / Color generating unit 15 as shown in Fig.

이와 같이 휘도신호와 컬러신호를 입력받은 휘도/컬러발생부(15)는 마이컴(14)의 제어신호에 의해 영상신호를 데크부(14)에 기록하거나 테이프에 기록된 자기신호를 재생하여 합성영상신호를 출력하게 된다.The luminance / color generating unit 15 receiving the luminance signal and the color signal outputs the video signal to the deck unit 14 or reproduces the magnetic signal recorded on the tape by the control signal of the microcomputer 14, And outputs a signal.

이때 fsc부(16)는 VCR의 동기검파용 서브캐리어로서 팔방식일 경우 4.43MHZ 크리스탈로 공급된다.At this time, the fsc portion 16 is supplied as a subcarrier for synchronous detection of the VCR, and is supplied with a 4.43 MHz crystal as an arm type.

한편, 엔티에스씨 방식일 경우 메인클럭발진부(7)에서는 28.636MHZ의 주파수로 발진을 하게 되며, 팔 4fsc PLL부(10)는 발진을 하지 않게 되어 상기 메인클럭발진부(7)에서 출력된 28.636MHZ의 주파수를 1/2분주로 사용하므로서 동기신호발생부(9)에서는 수직동기주파수가 60HZ로 발생하게 되어 DSP부(11)에 공급하게 된다.On the other hand, in the case of the NTSC system, the main clock oscillating unit 7 oscillates at a frequency of 28.636 MHz, the arm 4 fsc PLL unit 10 does not oscillate, and the main clock oscillating unit 7 outputs 28.636 MHz And the vertical synchronization frequency is generated at 60 Hz in the synchronizing signal generating section 9 and supplied to the DSP section 11. [

따라서, DSP부(11)는 VCR부의 휘도/컬러발생부(15)에 휘도신호와 컬러신호를 인가하면 상기 휘도/컬러발생부(15)는 마이컴(14)의 제어신호에 의해 영상신호를 데크부(14)에 기록하거나 테이프에 기록된 자기신호를 재생하여 합성영상신호를 출력하게 된다.Therefore, when the DSP unit 11 applies the luminance signal and the color signal to the luminance / color generating unit 15 of the VCR unit, the luminance / color generating unit 15 generates the video signal by the control signal of the microcomputer 14, (14) or reproduces a magnetic signal recorded on a tape to output a composite video signal.

이때, fsc부(16)는 엔티에스씨 방식인 3.58MHZ의 엔티에스씨 서브 캐리어주파수로 동작하여 휘도/컬러발생부(15)에 인가된다.At this time, the fsc portion 16 operates at an IF signal subcarrier frequency of 3.58 MHZ, which is an entity system, and is applied to the luminance / color generating portion 15.

그러나 종래 캠코더는 엔티에스씨방식의 경우 엔티에스씨 TV에서만 신호를 재생할 수 있고, 팔방식의 캠코더는 팔방식의 TV에서만 신호를 재생할 수 있어 해외 영행시 방송방식이 서로 다른 지역에서 촬영한 테이프를 재생하여 볼수가 없으며, 팔방식의 캠코더로서는 엔티에스씨로 기록된 테이프를 재생할 수 없으며, 엔티에스씨방식의 캠코더로서는 팔방식으로 기록된 테이프를 재생할 수 없는 문제점이있었다.However, in the case of the conventional camcorder, the signal can be reproduced only on the NTSC TV in the case of the NTSC system, and the signal can be reproduced only on the arm type TV in the arm type camcorder. Thus, There is a problem that it is impossible to reproduce a tape recorded with the NTSC as a camcorder of the arm type and a tape recorded by the arm type can not be reproduced as an NTSC type camcorder.

본 발명은 이와 같은 종래의 문제점을 해결하기 위하여 영상을 촬영시 사용자가 팔방식 또는 엔티에스씨방식에 관계없이 촬영할수 있고, 녹화된 테이프를 재생시 팔방식으로 녹화된 테이프 또는 엔티에스씨방식으로 녹화된 테이프에 관계없이 재생가능하도록 한 것으로서 첨부된 도면에 의하여 본 발명의 구성 및 작용효과를 설명하면 다음과 같다.In order to solve such a conventional problem, the present invention has been made to solve the above-mentioned problems in the related art, and it is an object of the present invention to provide an apparatus and a method for recording an image, The structure and effect of the present invention will be described below with reference to the attached drawings.

이와 같이 구성된 본 발명의 작용효과는 도 2를 참고로 하여 설명하면 다음과 같다.The operation and effect of the present invention will be described with reference to FIG.

먼저, 도 3과 같이 현재 캠코더가 EE모드일 경우를 설명하면 다음과 같다.First, the case where the current camcorder is in the EE mode as shown in FIG. 3 will be described as follows.

카메라키이부(24)에서 팔방식의 모드가 선택되었으면 카메라마이컴(25)에서는 카메라키이부(24)에서 선택된 팔방식의 모드를 입력받아 메인클럭발진부(26)에서 28,375MHZ의 주파수를 출력시켜 타이밍발생부(27)에 인가한다.When the mode of the arm mode is selected in the camera key section 24, the camera microcomputer 25 receives the mode of the arm mode selected by the camera key section 24 and outputs the frequency of 28,375 MHz in the main clock oscillation section 26, To the generating section (27).

이때 타이밍발생부(27)에서는 카메라마이컴(25)에서 출력된 시리얼 데이터에 의해 팔방식의 모드로 세팅되어 CCD부(21)에 공급되고 동시에 동기신호발생부(28)는 카메라마이컴(25)에서 출력된 제어신호에 의해 팔방식모드데이타로 세팅되면서 팔 4fsc PLL부(29)를 구동시켜 상기 메인클럭발진부(26)에서 출력된 클럭과 서브캐리어위상을 보정하여 DSP부(30)에 공급하고 수직동기신호를 50HZ로 동작시키므로서 카메라에서 촬영된 신호는 팔방식의 VCR부에 전달된다.At this time, the timing generator 27 is set to the arm mode by the serial data outputted from the camera microcomputer 25 and supplied to the CCD unit 21, and at the same time, the synchronization signal generator 28 And outputs the clock signal and the subcarrier phase output from the main clock oscillation unit 26 to the DSP unit 30 and supplies the corrected clock and subcarrier phase to the DSP unit 30, Since the synchronous signal is operated at 50HZ, the signal photographed by the camera is transmitted to the arm type VCR unit.

그리고, 카메라키이부(24)에서 엔티에스씨방식의 모드가 선택되었으면 카메라마이컴(25)은 메인클럭발진부(26)에서 엔티에스씨방식의 28.636MHZ주파수를 출력하여 타이밍발생부(27)에 인가하면서 동시에 동기신호발생부(28)에 연결된 팔 4fsc PLL부(29)는 동작하지 않게 되므로서 수직동기신호는 60HZ로 신호를 엔코딩하게 된다.When the mode is selected in the camera key unit 24, the camera microcomputer 25 outputs the 28.636 MHz frequency of the NTSC system in the main clock oscillation unit 26 and outputs the 28.636 MHz frequency to the timing generator 27 At the same time, the 4f sc PLL unit 29 connected to the sync signal generating unit 28 does not operate, so that the vertical sync signal is encoded at 60 Hz.

이때 판단부(37)는 검출부(31)에서 검출된 신호에 의해 현재 녹화모드가 엔티에스씨방식인지 팔방식인지를 판단하여 엔티에스씨방식이면 기록재생조절부(38)는 판단부(38)에서 판단된 방식을 입력받아 서브캐리어주파수변환부(40)를 조절하여 3.58MHZ의 서브캐리어를 휘도/컬러발생부(32)에 인가한다.At this time, the determination unit 37 determines whether the current recording mode is the NTSC system or the ARM system based on the signal detected by the detection unit 31. If the recording mode is the NTSC system, the recording / And controls the subcarrier frequency converter 40 to apply a subcarrier of 3.58 MHZ to the luminance / color generator 32. The luminance /

따라서, 휘도/컬러발생부(32)는 기록재생조절부(38)에서 조절된 신호와 서브캐리어주파수변환부(40)에서 출력된 신호를 입력받아 휘도신호와 컬러신호를 출력하게 되고 동시에 데크부(39)는 기록재생조절부(38)에 의해 엔티에스씨방식으로 주행하여 영상신호를 테이프에 기록하게 된다.Accordingly, the luminance / color generating unit 32 receives the signal adjusted by the recording / regulating adjusting unit 38 and the signal output from the subcarrier frequency converting unit 40, and outputs the luminance signal and the color signal. At the same time, (39) is driven by the recording / playback control unit (38) in an enthusiastic manner to record the video signal on the tape.

상기와 같이 DSP부(30)에서 출력된 휘도신호와 컬러신호를 검출부(31)에서 입력받아 팔방식인지 또는 엔티에스씨방식인지를 검출하여 판단부(37)에 인가하므로서 상기 판단부(37)에서 현재의 녹화모드가 팔방식으로 판단되었으면 자동적으로 데크부(39)를 통하여 팔방식의 영상을 테이프에 기록하게 된다.The determination unit 37 detects whether the luminance signal and the color signal output from the DSP unit 30 are received by the detection unit 31 and whether the system is the arm system or the entity system, When the current recording mode is determined to be the arm mode, the image of the arm type is automatically recorded on the tape through the deck unit 39.

팔방식으로 녹화된 테이프를 재생하고자 할 경우 데크부(39)에서 재생출력된 신호를 증폭부(34)에서 증폭출력시 복조부(35)는 상기 증폭부(34)에서 증폭출력된 신호를 원래의 신호로 복조한후 팔/엔티에스씨검출부(36)에 인가하게 되면 상기 팔 /엔티에스씨검출부(36)는 복조부(35)에서 복조출력된 원래의 신호가 서브캐리어나 수직동기주파수로서 팔방식인지 또는 엔티에스씨방식인지를 검출하여 판단부(37)에 인가하므로서 상기 판단부(37)는 팔/엔티에스씨검출부(36)에서 검출된 신호를 판단하게 된다.When a tape recorded in the arm mode is to be reproduced, the demodulating unit 35 demodulates the signal amplified by the demodulating unit 34 when the signal reproduced by the deck unit 39 is amplified by the amplifying unit 34, If the original signal demodulated and outputted by the demodulation unit 35 is a subcarrier or a vertical synchronizing signal having the same frequency as the subcarrier or the vertical synchronization frequency And the determination unit 37 determines whether the signal is detected by the arm / entity detection unit 36. In this case,

판단결과 팔/엔티에스씨검출부(36)에서 검출된 신호가 팔방식일 경우 기록재생조절부(38)는 판단된 신호에 의해 테이프에 기록된 신호를 팔방식으로 재생하게된다.As a result of the determination, if the signal detected by the arm / entity detecting unit 36 is of the arm type, the recording / reproducing control unit 38 reproduces the signal recorded on the tape by the determined signal in an arm manner.

반대로, 엔티에스씨방식으로 녹화된 테이프를 재생하고잘 할 경우에는 상기에서와 같이 판단부(37)에서 엔티에스씨방식으로 판단되었으면 기록재생조절부(38)는 판단된 신호에 의해 테이프에 기록된 신호를 엔티에스씨방식으로 재생하게 된다.On the contrary, if the tape recorded in the NTSC format is reproduced and is good, if the determination unit 37 determines that the tape has been recorded in the NTSC format as described above, the recording / playback control unit 38 records And reproduces the signal in the NTSC format.
