DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of a camera integrated video cassette recorder according to the present invention will now be described in detail with reference to the accompanying drawings.

1 shows a schematic perspective view of the appearance of a camera integrated video cassette recorder according to the invention. As can be seen in FIG. 1, the front panel of the video cassette recorder main body 1 is provided with a door 2 into which a tape cassette (not shown) can be inserted, as in a conventional video cassette recorder. . The tape cassette inserted into this door 2 may be a 1/2 inch VHS cassette or an 8 mm cassette. The right side of the front panel is equipped with a camera 3 capable of capturing a subject, which is fixed inside the video cassette recorder main body 1, but a separate camera is mounted on the video cassette recorder main body 1. It may be installed externally. Thus, in this invention the camera may be operated remotely.

The front panel is provided with various keys and lamps for controlling the operation of the camera integrated video cassette recorder of the present invention. For example, the power button 4A, stop / eject button 4B, jet viewing 4C, display window 4D, recording lock 4E, release button 4F, recording button 4G, TV / VIDEO switch button (4H), channel selection button 4I, pause button 4J, playback lamp 4K, and adjustment section 4L provided with a plurality of buttons for adjusting contrast, bright, and the like.

In the camera-integrated video cassette recorder shown in FIG. 1, since the camera 3 is integrally formed, it is possible to photograph a subject in a natural atmosphere while being mounted on a table at a meeting or consultation or at home. Therefore, according to the present invention, the desired object can be achieved by attaching only the camera to the video cassette recorder even without a separate camcorder.

FIG. 2 is an internal block diagram of the camera-integrated video cassette recorder shown in FIG. 1, in which a broadcast signal input through the antenna 10 (including a camera signal from the detachable camera described later) is transmitted to the broadcast signal receiver 11. Is approved. The broadcast signal receiver 11 is configured to tune the input signal and apply it to the demodulator 12.

The demodulator 12 demodulates the signal tuned by the broadcast signal receiver 11 into a video signal and an audio signal, and provides the demodulated signal to the terminal X1 of the input signal selector 13. The input signal selecting section 13 receives a signal input from the external signal input section 14 (which typically includes a video audio jack) through the terminal X2 and processes a signal from the camera 3. The signal of 15 is received through the terminal X3.

Accordingly, the input signal selector 13 selects signals applied to the input terminals X1 to X3 according to the state of the control signals A and B from the microcomputer 16. Here, the input signal selector 13 preferably comprises two multiplexers capable of selecting the video signal and the audio signal by the microcomputer 16. Although only one multiplexer is shown in FIG. 2 for the sake of simplicity of the drawings and the specification, the present invention is not limited thereto.

The signal selected by the input signal selector 13 is input to the automatic gain adjustment amplifier 17, and the input signal level thereof is maintained at a constant signal level by the automatic gain adjustment amplifier 17, so as to the video signal processing unit 18. Is approved.

The video signal processing unit 18 provides the input video signal and audio signal to the recording unit 19 to cause the recording head 20 to record on a video tape (not shown), or the video through the playback unit 21. The content recorded on the tape is reproduced by the playhead 22 to produce a signal that can be viewed on a television monitor.

The signal processed by the video signal processing unit 18 is applied to the video signal amplifying unit 23 and maintained for reproduction by a television or a monitor, and then converted into a television signal that can be received by the television via the RF converter 24. This will be explained in more detail.

In the present invention, three inputs (in some cases, more than one) can be selected. That is, a normal broadcast signal (or a video signal and an audio signal modulated at a broadcast frequency) is tuned to a specific frequency signal by the broadcast signal receiver 11 and demodulated by the demodulator 12 and then used as a video signal and an audio signal. It is input to the input terminal X1 of the multiplexer 13.

On the other hand, as the external signal input unit 14, a normal video signal and audio signal are generally input directly from an A / V device or from a special device that generates the video signal and sound signal. In addition, the video camera unit 15 applies the image information converted into an electrical signal through the lens and the audio signal input through the condenser microphone 30 (see Article 1) to the multiplexer 13.

At this time, the multiplexer 13 selects an input signal according to the control signals A and B of the microcomputer 16 as shown in Table I below.

As can be seen from Table-1 above, when the control signal is AB = LL, the multiplexer 13 selects a broadcast signal, and when AB = LH, an external input signal is selected and AB = HL In this case, a camera signal may be selected.

3 shows a detailed block diagram of the camera unit 15 shown in FIG. 2, in which the audio signal by the condenser microphone 30 is amplified by the microphone amplifier 31 and output as an audio signal. The signal for the subject passing through the camera lens 32 is converted into an electrical signal by the image pickup device 33 and then provided to the automatic gain adjuster 34. The automatic gain adjuster 34 performs an operation such as white balance and outputs a video signal of an appropriate level to the video signal processor 35 so that a video signal can be output therefrom.

As can be seen in Figure 3, the camera unit has a built-in power supply 36, the power supply 36 is capable of generating a plurality of voltages, as will be described later The battery 37 is built in case of the additional detachable type. A battery charging unit 38 capable of charging the battery 37 at any time is provided, and a power switching unit 39 for switching the power supply from the battery 37 and the normal power input is provided.

4 is a schematic configuration diagram of a remote camera in which the modulator 40 is built in the camera 3, and a transmission antenna 41 is attached to this camera. This camera is attached to an arbitrary place separately from the camera 3 shown in FIG. 1 so that a video signal and an audio signal can be transmitted to the video cassette recorder main body. Accordingly, the camera integrated video cassette recorder according to the present invention may be integrated with the camera as shown in FIG. 1, or by installing a separate camera as shown in FIG. There is an advantage in that the signals captured by the separate cameras of Fig. 4 and Fig. 4 can be recorded on video tape or monitored as a TV. If several separate cameras are installed, they can be used as surveillance cameras.

As described above, if a camera-integrated video cassette recorder is used as a surveillance camera so that a moving object, i.e., a moving body can be detected in a predetermined space, the camera-integrated video cassette recorder may automatically capture a moving body, You can also print a specific message. A body detecting method and a device of the camera-integrated magnetic recording and reproducing apparatus will be described.

5 and 6 are for detecting the fuselage, the same components as those in FIG. 2 have the same reference numerals, and the description of the same configuration and operation will be omitted.

First, FIG. 5 shows an image discriminator 100 which compares an image input from the camera 15 with a pre-stored image as a means for body motion detection. Outputs a control signal for performing magnetic recording or magnetic reproduction operations. The image discriminator 100 samples the switch 101 selectively outputting the image signal input from the camera 15 by the control signal C1 of the microcomputer 516, and sampling the selected image signal. A sampling unit 102, an A / D converter 103 for converting the sampled analog signal into a digital signal, a memory 104 for storing the signal converted into a digital signal, and an output of the A / D converter 103. A comparator 105 for comparing the image and the output image of the memory 104 and outputting a signal corresponding to the difference, a low pass filter 106 for filtering the compared signal, a reference voltage level and a low pass filter 106 And a comparator 107 for comparing the signals of the < RTI ID = 0.0 >

According to the signal output from the comparator 107 of the image discriminator 100, the microcomputer 516 controls the operation of the recording unit 519 or the reproduction unit 512 according to the mode set by the user (C2). ), (C3) is connected to output.

Accordingly, in FIG. 5, the comparison reference image is previously stored in the memory 104, and then the recording unit 519 and the head 20 according to the result of comparing the image stored in the memory 104 with the image input from the camera 15 in advance. The input image is self-recorded through the < RTI ID = 0.0 >), or < / RTI >

Specifically, the operation will be described by dividing the monitoring mode and the message output mode that can be set in the microcomputer 516. The surveillance mode detects the body and photographs the detected body, and the message mode detects the body and outputs a message including a pre-stored image. First of all, to execute the monitoring mode, the user must save the comparison reference image.

That is, the image input from the camera 15 is input to the sampling unit 102 through the switch 101 by the control signal C1 of the microcomputer 516. The sampling unit 102 samples the input image. The reason for going through the sampling process is to reduce the amount of memory required to store the data by sampling the minimum image data necessary for comparison without comparing the entire image data when comparing the images. The sampled image is converted into a digital signal by the A / D converter 103 and then stored in the memory 104. At this time, the read control signal is output from the microcomputer 516 to control the data read of the memory 104.

When the monitoring mode is executed after storing the comparison reference image, the microcomputer 516 outputs the control signal 'AB' to 'HL' so that the signal of the camera 15 is output from the multiplexer 13. The camera signal is input to the sampling unit 102 via the switch 101. The sampling unit 102 samples and outputs the input image, and the A / D converter 103 converts the sampled output image into a digital signal and inputs it to the comparator 105. On the other hand, the microcomputer 516 outputs a write control signal to output an image pre-sampled and stored in the memory 104 to the comparator. Accordingly, the comparator 105 compares the output image of the A / D converter 103 with the output image of the memory 104 and outputs a signal corresponding to the result, which is filtered by the low pass filter 106. The comparator 107 is then compared with the preset reference voltage Vref and compared, and the result is input to the microcomputer 516. The microcomputer 516 outputs the control signal C2 according to the output signal of the comparator 107 to perform a recording operation. When there is a difference between the image stored in the memory 104 and the image input through the camera 15 A recording operation is performed, and if there is no difference, the operation of comparing the input image with the stored image is performed.

Therefore, when the fuselage exists in the predetermined space, the camera-integrated video cassette recognizes it, photographs the fuselage, and performs a surveillance mode.

In order to execute the message output mode, an output message must be stored in advance. The message output mode detects the body and outputs a message. For example, if the wife goes out before her husband's leave of work due to urgent business, the message is stored using the camera's integrated video cassette recorder. When the body is detected by the integrated magnetic recording and reproducing apparatus, the camera integrated video cassette recorder outputs the stored message.

In order to detect the body and output the message, the message to be printed after the body is first detected must be stored. That is, the user operates the camera 15 to capture a desired message, and the photographed message is self-recorded via the AGC 17, the video signal processing unit 18, and the recording unit 519.

Then, when the microcomputer 516 is set to the message output mode by the user, the camera-integrated video cassette recorder detects the body as in the surveillance mode. When the fuselage is detected, the microcomputer 516 outputs a control signal C3 to operate the playback unit 521 to reproduce a prerecorded message, which is then amplified with the video signal processing unit 18. The display unit 23 displays a water pipe not shown.

Therefore, the message stored in advance is output, so that the person detected by the fuselage can check the message.

6 shows a fuselage detecting sensor as a means for detecting the fuselage. At this time, examples of those that can be used as a fuselage detecting sensor include an infrared sensor, an ultrasonic sensor, or a sensor for detecting atmospheric pressure or flow of air which is generally used.

Even when the fuselage detecting sensor is configured, the two modes described in FIG. 5, that is, the monitoring mode and the message output mode, are the same. The only difference is the detection of the fuselage. That is, FIG. 5 detects the fuselage by determining an image input to the camera 15, but FIG. 6 configures a separate fuselage detecting sensor. The microcomputer 616 operates the fuselage detection sensor 150 according to a user's mode operation, and then determines a signal input from the fuselage detection sensor 150 to perform an operation corresponding to the set mode.

That is, when the body detection signal is input to the microcomputer 616 from the fuselage detection sensor 150 in the monitoring mode, the camera 15 and the recording unit 619 take a picture of the body and record it in the message output mode. When the fuselage detection signal is input from the sensor 150 to the microcomputer 616, the playback unit 621 displays a prestored message on the water pipe (not shown) via the video signal processing unit 18 and the video signal amplifying unit 23. do.

7 is a flowchart illustrating a method of detecting a body of the camera-integrated magnetic recording and reproducing apparatus of FIGS. 5 and 6.

This is roughly divided into three processes, which consists of a body shooting process and a message storing process according to the driving of the camera after body detection, and a message output process stored after body detection.

If the mode of recording the signal photographed through the camera in step S1 (also called closed-loop television mode: CCTV mode hereinafter), step S2 is received, and the function selected in step S2 is monitored in step S3. If it is determined to be a function, a fuselage photographing process according to driving of the camera is performed after the fuselage detection. If it is determined in step S3 that is not a monitoring function and in step S4 it is determined that it is not a message output function, a message storing process is performed. do.

If it is determined in step S3 that the monitoring function, the monitoring state is set in step S31. The monitoring state outputs control signals for operating the image discriminator 100 and the fuselage detecting sensor 150 as the fuselage detecting means of FIGS. 5 and 6. After performing step S32, in operation S33, a separate operation is performed according to whether there is a fuselage. That is, when it is determined that the fuselage is present, the camera 15 is driven in step S34 and the control signal 'AB' is output as 'HL' so that the output signal of the multiplexer 13 becomes the signal captured by the camera 15. At the same time, after starting the recording operation, step S34 is repeated until there is no fuselage. If it is determined in step S33 and step S35 that there is no fuselage, it is determined whether the monitoring function is to be continued. If the monitoring function is still performed, the process returns to step S32, and an interrupt of the user or a pre-programmable monitoring function is reserved. If the time is exceeded, stop the monitoring function.

If the message output function is not the function of outputting the message in step S4, after driving the camera and the recording unit (S41), the step of storing the message (S42) and confirming whether the message is stored (S43) is repeatedly performed. Save the message. Message storage is the same as described in FIGS. 5 and 6.

If the message output function is detected in step S4, the body is detected in step S5. If there is a detected body, the playback unit is driven in step S7 to output a message. After performing steps S6 and S7, it is determined whether to continue the message output function. If the message output function is continued, the process returns to step S5. To confirm the selection of another function. Similarly, after performing steps S36 and S43, another function selection confirmation is performed. That is, in order to select another function by performing step S9, the process returns to step S2 and the operation ends if no other function is selected.

Accordingly, the fuselage detecting apparatus using the camera-integrated magnetic recording and reproducing apparatus detects the fuselage and outputs a message if the mode set by the user is a message mode, and photographs the fuselage if the mode set by the user is a monitoring mode.

As described above, according to the fuselage detecting method and apparatus of the camera-integrated magnetic recording and reproducing apparatus according to the present invention, theft can be prevented by detecting the fuselage in a predetermined space and recording the fuselage in the absence of the user. It is also possible to save the message and output the message when detecting the fuselage.
