BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a television for surveillance, and more particularly to a television for surveillance having both an entertainment function and a surveillance function.

For example, a business owner who buys a prize from Pachinko is outside a prize exchange office, where a surveillance video camera is installed to monitor a suspicious person. However, it is easy to become bored by the image of the surveillance video camera only, and the surveillance effect is also inferior, so that the television is often enjoyed in the leisure time when a visitor is cut off. Therefore, the prize exchange office has a monitoring image display and a television in parallel.

In the above-mentioned conventional surveillance television, two or more water receivers must be arranged in narrow prize exchange offices, etc., and there is a problem that it is inefficient. Moreover, even if two water receivers were provided, there was also a problem that the mind was sold only to television broadcasting, and the surroundings were easily neglected by the surveillance image.

This invention is made | formed in view of the said subject, Comprising: It aims at providing the monitoring television provided with both functions of monitoring and entertainment with one water receiver.

In order to achieve the above object, the present invention relates to a surveillance video camera, a television tuner, and output signals of the surveillance video camera and the television tuner. To display the captured image of the surveillance video camera on its own screen, and to display the captured image of the surveillance video camera on the mother screen if necessary, and to display a control screen by the mother screen control circuit. An image display device and a human body detecting device connected to the telephone input terminal of the mother-screen control circuit for detecting a human body are provided.

In the invention according to the present invention configured as described above, normally, the receiving image of the television tuner is used as the mother screen, and the photographed image of the surveillance video camera is displayed on the image display with the own display, and the monitor enjoys television broadcasting. Surveillance can also be done. On the other hand, when the visitor enters, the captured image of the surveillance video camera can be displayed on the mother screen, so that the surveillance image can be seen more reliably.

As described above, the present invention can monitor at the same time without getting tired of the monitor that tends to be bored, so that it is possible to provide a television for surveillance which can be more surely monitored.

EXAMPLE

EMBODIMENT OF THE INVENTION Hereinafter, embodiment of this invention is described based on drawing.

FIG. 1 is a block diagram of a surveillance television according to an embodiment of the present invention, and FIG. 2 is a schematic diagram showing an entire surveillance system to which a surveillance television is applied.

In FIG. 2, the video camera (surveillance video camera) 10 is arranged to face a monitoring location for monitoring, and the image signal is inputted on one side of the mother-screen control circuit 20 on one side. Is connected to. The mother-screen control circuit 20 includes another input terminal 22 together with the input terminal 21, and a television tuner 30 is connected to the input terminal 22. The television tuner 30 includes a channel operator 31 and a volume operator 32. When the television tuner 30 operates both operators 31 and 32 to select a desired television broadcast, the television tuner 30 receives the selected television broadcast. The video signal and the audio signal are output to the mother screen control circuit 20.

The mother-screen control circuit 20 uses one image as a mother screen and the other screen as a child screen to the image signals inputted to the two input terminals 21 and 22, and displays the image signal of one screen. Normally, the image input to the input terminal 22 is the mother screen, but when the switching signal is input to the switching input terminal 23, the image input to the input terminal 21 is the mother screen. .

The infrared detecting device 40 is connected to the switching input terminal 23 in the mother screen control circuit 20. The infrared detection device 40 includes an infrared sensor 41 installed in parallel with the video camera 10, and the hat screen control circuit when a human body (object) emitting infrared rays enters the shooting range of the video camera 10. A switching signal is output to (20). In addition, in the present embodiment, a changeover switch 42 for manually outputting a changeover signal is also provided.

The hat screen control circuit 20 is provided with a hat screen output terminal 25 and a monitoring screen output terminal 26, and an image display 50 is connected to the hat screen output terminal 25. The mother screen output terminal 25 outputs the image signal of the mother screen generated by the mother screen control circuit 20 and the audio signal from the television tuner 30. The image display 50 monitors television images and monitors. The image is displayed on the hat screen.

On the other hand, a video tape recorder 60 is connected to the monitoring screen output terminal 26, and the video recording recorder 60 is connected to the monitoring screen output terminal 26 together with the captured image signal of the video camera 10. The recording control signal is output.

The mother-screen control circuit 20 reverses the relationship between the television image constituting the mother-screen and the surveillance image upon input of the switching signal, but at the same time, the video tape recorder 60 connected to the surveillance screen output terminal 26 is connected. Outputs a control signal to start recording. In response to this, the video tape recorder 60 normally waits in the recording standby state. However, as described above, when the control signal for starting the recording is output to the monitoring screen output terminal 26, the video camera ( Recording of the photographed image of 10) is started.

In FIG. 2, the mother-screen control circuit 20, the television tuner 30, the infrared detection device 40, etc. are accommodated in the case 70. In FIG.

Next, the operation of the present embodiment having the above configuration will be described.

When no human is in the shooting range of the video camera 10, the infrared sensor 41 of the infrared detecting device 40 does not detect infrared rays and does not output a switching signal.

At this time, the mother-screen control circuit 20 displays the landscape of the monitoring range input to the input terminal 21 as its own screen, and the television screen selected by the monitor by manipulating the operators 31 and 32 as the mother screen. An image signal as shown in FIG. 2 is generated and output to the image display unit 50.

The watcher enjoys the television broadcasting mainly reflected on the entire screen, and the monitor image is small in the corner of the same screen, so the monitor does not neglect the surveillance work.

On the other hand, when a human approaches within the shooting range of the video camera 10, the infrared sensor 41 of the infrared detecting device 40 detects the infrared rays emitted by the human, and outputs a switching signal to the mother-screen control circuit 20. do. When the switching signal is input, the mother-screen control circuit 20 sets the image signal output from the video camera 10 as the mother screen as shown in FIG. 3, and at the same time, the television tuner 30 outputs the television broadcast. The child image is made into the child screen, and the mother-child relationship so far is reversed.

As a result, the monitor can monitor this person with a large monitoring image. In addition, since the mother-screen control circuit 20 outputs a control signal from the monitoring screen output terminal 26 to start recording with respect to the video tape preorder 60, the video tape precoder 60 performs recording of the monitoring image. To start. At this time, the image recorded by the video tape recorder 60 is not a hat screen, but only a surveillance image photographed by the video depot camera 10 reproduced as shown in FIG. Done. In addition, the image to be taken superimposes the date and time.

When the human retreats, the infrared sensor 41 does not detect the infrared rays, and the infrared ray detection device 40 does not output the switching signal to the mother-screen control circuit 20. Then, the mother-screen control circuit 20 outputs a control signal to end video recording to the video tape recorder 60 while switching the surveillance image to the mother screen as the mother screen as before.

Thus, the video tape preorder 60 ends the recording and returns to the standby state. In this manner, since the video tape recorder 60 records images only when necessary, the video tape recorder 60 can efficiently see the images when they need to be viewed later.

In addition, even when the human being in the shooting range is an unrelated human being, the television broadcast is reflected on the own screen, and the audio is also heard on the television screen. I can enjoy it. In particular, since the sound of television broadcasting continues, the contents of the television are not interrupted entirely, so entertainment can be maintained.

The surveillance television of the present invention is very effective when used in, for example, a prize exchange office of a pachinko, or in a guard room of a building. Of course, the video cameras 10 may be arranged indoors or disposed outdoors. In the present embodiment, one video camera is used, but the plurality of video cameras 10 are connected to each other, and the mother-screen control circuit 20 illuminates the plurality of child screens, or the video camera 10 is switched every predetermined time. You may switch. Instead of the television tuner 30, a video deck or a combination of both may be used.

In the present embodiment, the human body is detected by the infrared detection device and the hat screen is automatically switched. However, even when the human body is detected, the human body can be switched manually or completely manually.
