CCD video camera which is able to multi-devision photographing}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a charge coupled device (CCD) video camera capable of multi-segment shooting, and in particular, it is possible to display a single monitor screen by dividing the image screen according to the position shooting of several targets without using a screen splitter. It's all about technology.

In general, a video camera using a CCD sensor is also widely used for surveillance to observe an object. The configuration of the CCD video camera processes a CCD sensor that can sense an image, a timing pulse generator that generates various pulses required to drive the CCD sensor, and an image signal output from the CCD sensor. The state is largely divided into video processors.

According to the above configuration, one video camera is formed. For example, in order to capture the positions of several targets simultaneously and display them as images through one monitor, a screen splitter for dividing an image screen according to individual target shooting is required. .

In this case, the screen splitter is a device that receives a video image signal corresponding to a predetermined number and divides it on a general monitor to simultaneously display it.

In addition, a method of receiving and dividing a plurality of video signals at the same time is to use a special monitor for dividing, which can receive and display several video signals simultaneously at the monitor itself.

In this case, the reason for using this method is that the video camera generally has only one sensor and views only the image of one location. For example, if a video camera has two or more sensors, and each sensor faces a different direction, it is possible to capture an image of positions of completely different targets.

However, the following problems are exposed by using the above general method.

Second, in order to compose four or two divided screens into an existing CCD video camera, for example, a screen splitter and a special monitor for splitting must be purchased.

Accordingly, an object of the present invention is to solve the above problems, and an object of the present invention is to mount a plurality of CCD sensors on a single CCD video camera, so that multiple shots capable of capturing multiple targets at the same time are possible. To provide a video camera.

Another object of the present invention is to provide a CCD video camera capable of multi-segment imaging, which allows an image relating to a target position photographed by a CCD video camera to be divided and displayed through one monitor.

Hereinafter, with reference to the accompanying drawings, the configuration and operation of the embodiment of the present invention will be described in detail.

1 is a circuit diagram of a CCD video camera according to the present invention.

Referring to the circuit diagram of the CCD video camera shown in FIG. 1, each CCD sensor unit 10 is connected to the video processor unit 70, respectively, and an output end of the video processor unit 70 is a monitor unit (not shown). ) In addition, the timing pulse generator 50 is connected to the respective horizontal and vertical driving units 60, respectively.

First, the CCD sensor unit 10 is installed in the video camera lens one by one in different directions, so that the four first, second, third, fourth CCD sensor units 12, 14, 16, 18 to be divided into four according to the position of the target. ) To detect the location of each target.

Of course, when the first camera 12 and the second CCD sensor 14, that is, two CCD sensor 10 in the video camera is installed in the front, rear or up, down, left and right directions to detect the target Done.

The first, second, third, and fourth video processor units 72, 74, 76, and 78 of the video processor unit 70 output from the first, second, third, and fourth CCD sensors 12, 14, 16, and 18. The video signal or the timing pulse signal generated from the timing pulse generator 50 receives the image and outputs it to the monitor. Image data processed by only four first, second, third, and fourth video processors 72, 74, 76, and 78 are later synthesized into one and converted into a complete video signal. Since the conditions of the images directed by the 3,4 CCD sensor units 12, 14, 16, and 18 are all different, images captured by the respective CCD sensor units 10 must be independently processed. Therefore, one video processor unit 70 processes each CCD sensor unit 10 independently, and combines the video signals in one video processor unit 70 in accordance with the synchronization signal in common at one end to synthesize one image. The timing pulse generator 50 generates various timing pulses required for driving the first, second, third, and fourth horizontal and vertical drivers 62, 64, 66, and 68, and generates timing pulses. Outputs various input / output signals generated from the unit 50 to the video processor unit 70. Here, how the image data output from the four CCD sensor unit 10 shown in FIG. The process of whether four images are properly synthesized as one will be described. The timing pulse generator 50 allows the CCD sensor unit 10 to capture an image and transmit the image to the video processor unit 70 for processing. Make all the waveforms, If the output waveform of the timing pulse generator 50 is well designed, the above process can be solved simply. That is, the first, second, third, and fourth CCD sensor units 12, 14, 16, and 18 4, the image is divided and displayed as shown in FIG. 4. The first CCD sensor unit 12 is positioned at the upper left side 90a of the monitor, and the second CCD sensor unit 14 is positioned at the upper right side 90b of the monitor. The third CCD sensor 16 and the fourth CCD sensor 18 are positioned at the lower left 90c of the monitor and the lower right 90d of the monitor, respectively. The scanning line of the monitor is located from the upper left of the monitor. Up to the lower right, 525 units of the National Television System Committee (NTSC) system and 625 units of the Phase Alternating by Line system (PAL) system pass. When passing the area where the image of (12) is scattered, only the first CCD sensor unit 12 is a timing pulse. When the generation unit 50 drives to output an image, and the scanning line passes the area where the image of the second CCD sensor unit 14 is scattered, only the second CCD sensor unit 14 drives the timing pulse generator 50 to drive the image. give. Of course, the same applies to the third CCD sensor unit 16 and the fourth CCD sensor unit 18. Therefore, even if all four CCD sensor units 10 are driven, the image is different in all sections in which the image is displayed on the actual monitor. There is no part where the image data output from the CCD sensor unit 10 overlap with each other. As described above, the first, second, third and fourth CCD sensors are divided by driving the timing pulse generator 50 properly. The parts 12, 14, 16, and 18 can all be driven. Therefore, each of the first, second, third, and fourth video processor units 72, 74, 76, and 78 processes only one quarter of the entire image. However, the important point here is that the main input clock frequency for driving the timing pulse generator 50 should use a clock frequency that is twice as fast as the timing pulse generator 50 for driving one CCD sensor.

The horizontal and vertical driving units 60 may include four first, second, three, four horizontal and vertical driving units to drive the four CCD sensors 12, 14, 16, and 18 as synchronization signals in the horizontal or vertical direction, respectively. 62,64,66,68).

The monitor unit (not shown) displays an image signal processed by the video processor unit 70 on the screen in two or four divisions.

The power supply unit (not shown) supplies voltage at each level required for driving each component.

Subsequently, the operation according to the configuration of the CCD video camera shown in FIG. 1 will be described. According to the signals of the various timing pulses generated from the timing pulse generator 50, the respective horizontal and vertical driving units 60 are horizontal, vertical, and horizontal. Each of the CCD sensors 10 detects the position of the target as an image by being driven by the synchronization signal in the vertical direction.

In case of detecting each target position by the CCD sensor unit 10, the image signal output from the CCD sensor unit 10 is input to each video processor unit 70 and processed according to a characteristic, and the image signal is integrated into one at the end. The video signal is converted into one video signal and input to the video processor unit 70.

The video processor 70 processes the input image signals and outputs them to the monitor unit so that the target image is displayed by dividing the display unit into two or four parts on the screen of the monitor unit.

FIG. 2 is a flowchart illustrating input and output terminals of the timing pulse generator shown in FIG. 1.

Referring to one and output terminals of the timing pulse generator shown in FIG. 2, the timing pulse generator 50 generates various timing pulses necessary for driving the horizontal and vertical drivers 60 to drive the CCD sensor unit 10. Will be created.

Of course, when two or four CCD sensor units 10 are generated, a timing pulse capable of simultaneously driving the horizontal and vertical driving units 60 of the CCD sensor unit 10 corresponding thereto is generated.

That is, the output of the timing pulse generator 50 has AV1, AV2, AV3, AV4, ASG1, ASG2, AH1, AH2, A × SUB, ARG terminals 50a, BV1, BV2, BV3, BV4, BSG1, BSG2. , BH1, BH2, B × SUB, BRG terminal 50b, CV1, CV2, CV3, CV4, CSG1, CSG2, CH1, CH2, C × SUB, CRG terminal 50c and DV1, DV2, DV3, DV4, DSG1 , DSG2, DH1, DH2, D × SUB, and DRG terminal 50d signals are output to drive the respective CCD sensor unit 10.

In addition, the timing pulse generator 50 has an aperture iris signal that receives a signal for adjusting the light quantity of each CCD sensor 10, that is, AED0, AED1, BED0, BDE1, CDE0, CDE1, DED0, DED1 terminals ( 50e) signals are input, and SHP, SHD, SYNC, BLK, CLP, HD, and VD terminals 50f are output.

Accordingly, by generating the respective timing pulses corresponding to the number of CCD sensors applied to the CCD video camera, the target image is displayed by dividing into two or four through the screen of the monitor.

3A to 3D are schematic diagrams of a video camera to which two or four CCD sensors are applied according to an embodiment of the present invention.

As shown in FIG. 3A, four CCD sensors 102, 104, 106, and 108 (not shown) are mounted on a CCD video camera lens 100 installed to face down from the ceiling, and thus targets that cannot be detected by one CCD sensor in the past. The position of the target can be detected, and the target position can be divided into four sections through the monitor to observe the three-dimensionally.

As shown in FIG. 3B, four CCD sensors 102, 104, 106 (not shown) and 108 (not shown) are mounted at left, right, front and rear positions of the CCD video camera, or the front and rear positions of the CCD video camera as shown in FIG. 3C. By mounting two CCD sensors 102 and 104 on the screen, the target object can be divided into four or two sections according to the purpose of use, and three-dimensional observation is possible.

In addition, as shown in FIG. 3D, four CCD sensors 102, 104, 106, and 108 may be mounted and used on only one surface of the CCD video camera.

Therefore, since the lenses of the CCD video cameras face different directions, each of the CCD sensor units 10 controls the aperture signal separately.

As shown in FIGS. 4 and 5, the image signals output from the four or two CCD sensor units 10 are finally processed by the video processor unit 70 and divided into four segments through the monitor unit 90 ( 90a, 90b, 90c, 90d) or divided into two (90a, 90b) and displayed as an image.

6 is a view illustrating a state in which a video processor and a CCD sensor are connected by a flexible cable in a video camera to which four CCD sensors are applied according to the present invention.

As shown in FIG. 6, each of the CCD sensor units 12, 14, 16, and 18 is connected to the video processor unit 70, the timing pulse generator unit 50, and a flexible cable 110. The direction of the CCD sensor units 12, 14, 16, 18 can be set as desired in the desired direction.

As described above, according to the CCD video camera capable of multi-division shooting according to the present invention, by mounting a plurality of CCD sensors in one CCD video camera, it is possible to simultaneously shoot multiple targets and photograph the target positions.

First, the screen splitter used to shoot target positions in different directions by providing a CCD video camera capable of simultaneously dividing two or four divisions away from the function of a video camera capable of capturing only an image of a single target position. It is advantageous in terms of installation and economics because it does not require the use of. Because four cameras are divided into four using a screen splitter, four cables are required to transmit video signals from each camera to the screen splitter. In addition, the screen splitter to the monitor must be reconnected with a cable, but in the present invention, it can be solved with one cable from the camera to the monitor.

Second, by connecting each CCD sensor with a video processor and a timing pulse generator with a flexible cable, it is possible to detect the position of the target by adjusting the direction of the CCD sensor at will in the desired direction.

As described above, the present invention has been described with reference to exemplary embodiments, but these descriptions should not be interpreted in a limiting sense.
