Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is useful when conducting market research for a specific product in a 24-hour shop, market, or department store. This is a market research support device used when conducting market research.

Conventional technology FIG. 2 shows the configuration of a conventional market research support device.

In FIG. 2, 1 is a television camera, and a video signal from the television camera 1 is input to a video recording section 2 capable of intermittent recording.

Next, the operation of the above conventional example will be explained. In FIG. 1, a television camera 1 obtains an image near a specific product,
The video recording unit 2, which is capable of intermittent recording, records only one frame at fixed time intervals (for example, every 2 seconds).

In this way, even with the above-mentioned conventional market research support device, it was possible to frame images around a specific product for 120 hours at a resolution of one frame every two seconds.

Problems to be Solved by the Invention However, the conventional market research support device described above has the following problems because it records images of the vicinity of a specific product at regular intervals.

■ Since unnecessary videos that do not show people are also recorded, the storage capacity is only about 120 hours if the resolution is maintained at one frame every two seconds.

■ When playing back tapes recorded with this device, it was necessary to check videos that did not include people, which required a large amount of manpower during playback.

The present invention solves these conventional problems,
The object of the present invention is to provide an excellent market research support device capable of recording only necessary images showing people.

Means for Solving the Problems In order to achieve the above object, the present invention enables a video recording section to be temporarily stopped and includes a moving object detection sensor and a control section for controlling the video recording section.

Effects The present invention has the following effects due to the above configuration. In other words, the video recording section is put into a paused state when the device is powered on, and each time the moving person detection sensor detects an object, the paused state is canceled and the video from the TV camera is recorded. Once finished, it can be paused, allowing you to record only the necessary footage that shows people. Also, recording media (tape)
As a means to prevent wear on the recording medium (tape), it is possible to record only one frame of an all-black image so as not to interfere with confirmation when playing back the recording medium (tape).

Embodiment FIG. 1 shows the configuration of an embodiment of the present invention. In FIG. 1, 11 is installed on the ceiling near a specific product,
This sensor 11 is a moving person detection sensor that detects the movement of a person based on ultrasonic reflected signals from the floor, etc., and this sensor 11 is input to the timing control section 15 in the control section 13. 1
2 is a television camera, and a video signal from this television camera 12 is input to an input sofa 16 in a control section 13. The video signal is output from the input port 716 to the video switch 17 and the sync separation circuit 18.

The synchronization separation circuit 18 separates only the synchronization signal to form an all-black image and input it to the video switch 17.

Further, the synchronization timing signal detected by the synchronization separation circuit 18 is connected to the timing control section 15. Reference numeral 14 denotes a video recording unit that can be temporarily stopped, and one of the signals selected by the video switch y-17 is given to the video recording unit 14 as a video signal in response to a signal from the timing control unit 15. Reference numeral 19 denotes a pause control drive unit, which controls the video recording unit 14 capable of controlling the -time stop according to the signal from the timing control unit 15, and cancels the -time stop or puts it into a paused state.20 indicates a pause. It is a monitor receiving section, and provides the timing control section 15 with a status signal indicating whether to pause or cancel from the video recording section 14. 21 is an initialization detection circuit, which provides a signal to the timing control section 15.

Next, the operation of the above embodiment will be explained.

In the above embodiment, the initialization detection circuit 21 generates a reset signal to the timing control section 15 when the device needs to be initialized, such as when the power is turned on. The timing control section 15 generates a control signal to the pause control drive section 19, and the -time stop control drive section 19 drives the pause switch of the video recording section 14 capable of -time stop control. - If the recording unit 14 in the pause monitor receiving unit 20 determines that the status signal from the video recording unit 14 capable of time-stop control is in a paused state, the pause monitor receiving unit 20 sends the status signal to the timing control unit 15. generates a status signal. When the timing control unit 15 receives the status signal from the pause monitor receiving unit 20, it stops sending the control signal to the -time stop control drive unit 19, and the -time stop control drive unit 19 temporarily stops the video recording unit 14. Stop driving the stop switch. The moving person detection sensor f-11 sends a detection signal to the timing control section 15 when a moving person is detected. The timing control unit 15 determines (the average travel time of the moving person from the sensor to the location to be imaged and the pause release state of the video recording unit) after a certain set time from the start of receiving the detection signal from the moving person detection sensor 11. - Control signals are started to be sent to the time/stop control drive section 19 so that the signal selected by the video switch y-17 becomes the video signal on the road. - When the time stop control drive section 19 receives the control signal, it drives the pause switch of the video recording section 14. When it is determined that the stop is released, the - hour stop monitor receiving unit 20 stops sending the status signal to the timing control unit 15.The timing control unit 15 stops sending the status signal from the pause monitor receiving unit 20. On the left, when the -time stop control drive unit 19 stops sending the control signal, the -time stop control drive unit 19 stops driving the pause switch of the video recording unit 14.The video on the road is , TV camera 2
The signal is imaged by the input buffer 716 to become a video signal, and is applied to the video switch 17 and the synchronization separator 18 through the input buffer 716. In the synchronization separation section 18, a signal obtained by extracting only the synchronization signal from the video signal (the video part is completely black) is sent to the video switch 17,
b The timing control unit 15 that provides a vertical synchronization timing signal to the timing control unit 15 monitors the vertical synchronization timing signal from the synchronization separation circuit 18 after the video recording unit 14 enters the pause release state, and At the timing when one-frame recording ends, the - hour stop control drive unit 1
Start sending control signals to 9.

- When the time stop control drive unit 19 receives the control signal, it drives the pause switch of the video recording unit 14. When the pause monitor receiving unit 20 determines that the status signal from the video recording unit 14 is in a paused state,
- The time stop monitor receiving section 20 starts sending a status signal to the timing control section 15. Timing control section 1
5, when the sending of the status signal from the pause monitor receiving unit 20 is started, the sending of the control signal to the -time stop control drive unit 19 is stopped, and the -time stop control drive unit 19 is activated by the video recording unit 14. Stops the drive of the pause switch. Furthermore, if the video recording section 14 remains paused for a certain period of time, the recording tape will wear out, so in this device, the timing control section 1
5, if the status signal from the -time stop monitor receiving section 20 is continuously received for a certain period of time or more, the timing control section 1
5 outputs a control signal to the pause control drive section 19, and controls the signal selected by the video switch f17 to be only a synchronization signal (all black signal). - When the time stop control drive section 19 receives the control signal, the video recording section 14
Drive the pause switch.

When the video recording unit 14 determines that the status signal from the video recording unit 14 is in the pause release state at the pause monitor receiving unit 20, the -time stop monitor receiving unit 20 transmits the status signal to the timing control unit 15. Stop sending. Sending of the status signal to the timing control unit 15 is stopped. When the sending of the status signal from the pause monitor receiving section 20 is stopped, the timing control section 15 stops sending the control signal to the -time stop control drive section 19, and -the time stop control drive section 1.
9 stops the driving of the pause switch of the video recording section 14. After the video recording unit 14 enters the pause release state, the timing control unit 15 monitors the vertical synchronization timing signal from the synchronization separation circuit, and the video recording unit 14 finishes recording one frame (all black video). At this timing, a control signal is started to be sent to the -time stop control drive section 19. - When the time stop control drive section 19 receives the control signal, the video recording section 1
Activate the pause switch No. 4. When the pause monitor receiving unit 20 determines that the video recording unit 14 is in a paused state based on the status signal from the video recording unit 14 , the -time stop monitor receiving unit 20 transmits the status signal to the timing control unit 15 . Start sending.

In the timing control section 15, the pause monitor reception section 20
When the transmission of the status signal from the -time stop control drive unit 19 is started, the -time stop control drive unit 19 stops driving the pause switch of the video recording unit 14. .

In this way (2) according to the above embodiment, the video recording unit 14 capable of being stopped at - hours is controlled to be in a pause state, and only when the moving person detection sensor 11 starts detecting a moving object, Since the control unit 13 is provided, the control unit 13 controls the video recording unit 14, which can be stopped, to a pause release state, and controls the video recording unit 14 to record the video on the road from the television camera 12.
- The video recording unit 14, which is capable of time-stop control, has the effect of being able to record only the necessary video that shows a person.

Further, since the means for preventing wear of the recording medium (tape) records an all-black image, there is an advantage that this image does not need to be checked when the recording medium (tape) is played back.

Effects of the Invention As is clear from the above embodiments, the present invention has the following effects.

■ Only the video of the vicinity of a specific product is recorded when the moving person detection sensor starts detecting a moving object.
It is possible to realize the maximum recording medium (tape) capacity for necessary images of people without impairing the resolution in terms of time.

■ When playing back the recording media (tape) recorded with this device, all videos played must be confirmed (required)
Since only images are used, the amount of manpower required for confirmation can be reduced.
