Abstract

PURPOSE:To specify an object by recording information to identify an object onto a video recorder such as a long time VTR together with a video signal of a TV camera simultaneously and retrieving the information at reproduction. CONSTITUTION:An ID card and collation information such as fingerprint, palm stamp or voice pattern of an object 3 are processed and recorded by a processing unit 2 and sent to an information signal multiplexer 5. The sent collation information as video information synchronously with the video signal from a character code generating circuit 12 is multiplexed on a video signal of a TV camera 4 by a multiplexer circuit 11 and recorded on a video recorder 6 such as a long time VTR. Moreover, the collation information coded by the character code generating circuit 12 is superimposed on the video signal of the TV camera 4 for the blanking period. Then the collation information is decoded from the reproduced video of the video recorder 6 such as a long time VTR and an object on purpose is retrieved automatically.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a TV camera monitoring system for the purpose of security such as room entry/exit control and crime prevention.

[Summary of the invention]

Conventionally, long-time V
From the playback images of video recording devices such as TR and video discs,
When searching for a specific subject, you can search while visually checking the contents of the playback image, or.

It is thought that the time display superimposed on the video signal and the target subject are recorded by a long-term VTR, etc., and a search method was used to compare the displayed times, but these are 1
In order to solve this problem, which was a time-consuming and labor-intensive method, the present invention uses a TV camera.

A monitoring system is constructed by combining a verification device that can provide information that can identify the subject, and the verification information from the verification device is multiplexed with the video signal of the TV camera and recorded on a VT-R etc. for a long time. The conventional monitoring system is to visually search the collation information displayed on the i! As shown in FIG. 3, there was an independent TV camera monitoring system consisting of a device TV 7 comprising an access control device using an ID card or the like, a cash dispenser etc. 1, and a processing device 2.

Therefore, it is necessary to search for a specific subject from among the video information recorded on the VTR6 for a long time. It was necessary to visually check the playback image of the VTR 6 for a long time while searching for the object σ).

In addition, in this monitoring system as well, from the processing device 2,
Check the information on the time when the desired subject entered and left the room, and
It is possible to search by referring to the time display recorded in the TR6 together with the video signal.

[Problem to be solved by the invention]

From images played back from video recording devices such as long-term VTRs.

You can search for specific objects by visually checking them one by one.

This is because the amount of video information on the recording device is the same as that of an art university. It requires a lot of effort and time. Furthermore, it was difficult to further identify the subject unless someone who could identify and confirm the subject searched for it.

In order to overcome these drawbacks, the present invention provides information for identifying the subject on a long-term video signal simultaneously with the video signal of the TV camera.
Record on a video recording device such as TR.

The aim is to construct a monitoring system that can identify the subject by searching for that information during playback.

[Means and effects for solving problem a] In order to achieve the above-mentioned object, the present invention is capable of converting verification information from a verification device such as an entry/exit control device using an ID card or a cashier dispenser into a numerical value or Should it be multiplexed into the TV camera video signal as character information such as symbols? Alternatively, it is multiplexed as coded information during the blanking period of the video signal, and is recorded on a video recording device such as a VTR for a long period of time, and is then played back.

You can visually check the matching information such as numbers and symbols multiplexed on the video signal on the monitor TV screen and search for the target subject, or you can check the matching information that has been coded and superimposed during the planking period of the playback video. It is electrically decoded to automatically search for the desired subject and play it back.

Note that instead of multiplexing the verification information into the video signal, it is also possible to record the verification information in the audio track or data recording track of the video recording device and then search.

〔Example〕

An embodiment of the present invention will be described below with reference to FIG.

1 is a well-known entry/exit control device, cash dispenser, etc., which checks the ID card or fingerprint of the subject 3.

This constitutes a verification device that verifies the person using body verification information such as palm shape and voiceprint. This verification information is processed, recorded, etc. in the processing device 2, and simultaneously sent to the video/information signal multiplexing device 5. This sent verification information is
As character information synchronized with the video signal by the character/code generation circuit 12.

The multiplex circuit 11 multiplexes the signal into the video signal of the TV camera 4 and records it on a video recording device 6 such as a long-term VTR.

Furthermore, if the collation information coded by the character/code generation circuit 12 is superimposed on the blanking period of the video signal of the TV camera 4. It becomes possible to decode the collation information from the reproduced video of the video recording device 6, such as a long-term VTR, and automatically search for the target subject.

tl! , 2 Figure (4) shows the video signal waveform of the TV camera.

CB) shows the video waveform when collation information is multiplexed as character information within the effective video signal, and (C) shows the video waveform.

A video waveform in which verification information is encoded and multiplexed within a planking period is shown.

〔Effect of the invention〕

According to the present invention, even a person who is unable to identify or confirm a specific subject from the reproduced image of a video recording device can search for it based on verification information such as an ID card. be.

Furthermore, if collation information is coded and multiplexed during the blanking period of the video signal, a specific copy can be automatically searched for by electrically decoding the code information.
