Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used in a surveillance device using a television camera. In particular, it is suitable for use in monitoring operating conditions of production facilities and logistics facilities.

[0002]

2. Description of the Related Art It is widely known that a subject to be monitored is a subject and an abnormality thereof is detected by using a television camera. For example, to detect anomalies that occur on the manufacturing line,
The applicant of the present application has proposed a recording editing method and apparatus disclosed in Japanese Patent Application Laid-Open No. 2-16891. To briefly explain this proposal, television cameras as image pickup devices are installed at a plurality of points on the manufacturing line, and the images are simultaneously displayed on one screen. Further, this video is recorded by the first recording device.

When an abnormality signal on the manufacturing line is detected and an automatically generated abnormality signal is sent to this apparatus, the video information recorded in the first recording apparatus is rewound for a predetermined time, The video is played back up to the detection time of the abnormal signal. This video is recorded on the second recording device. Therefore, the supervisor of the manufacturing line can immediately display on the screen only the image traced back for a certain time from the time when the abnormal signal occurs, and analyze the cause of the abnormal occurrence.

Alternatively, in the monitoring device disclosed in Japanese Unexamined Patent Publication No. 1-251458, two first recording devices are used, one of the first recording devices is detected as an abnormal signal, and the first recording device becomes the second recording device. Even when dubbing is being performed, the other first recording device continues to capture images of the monitored object.

In particular, Japanese Patent Application Laid-Open No. 2-168 by the applicant of the present application
The proposal disclosed by Japanese Patent Publication No. 91 can compare the situations at a plurality of locations on the same screen at the same time, and is therefore excellent for analyzing anomalies that occur on a manufacturing line that are often caused by multiple factors. ing. This conventional example will be described with reference to FIG. FIG. 11 is an overall configuration diagram of a conventional example. Imaging device 1 ₁ to 1 ₄ are imaging the image of the four places. These images are edited by the four-screen unit 6 so that they can be simultaneously reproduced on the same screen, and recorded on the first recording device 2. When an abnormal signal is sent from the line controller 8 to the control device 4 as the external input signal 5, the first recording device 2 rewinds the video tape for a predetermined time according to the time information from the control device 4, The contents are dubbed to the second recording device 3.
The monitor reproduces the video information recorded in the second recording device 3 and displays it on the monitor 13 to analyze the abnormality of the monitored object.

[0006]

As described above, it is useful to display images at a plurality of locations on the same screen at the same time and analyze anomalies on the manufacturing line. For example, one and the same work piece flowing on the manufacturing line can be used. Cannot be monitored for. That is, the same workpiece one flowing on the production line, always with a time difference to pass through the front of the imaging apparatus 1 ₁ to 1 _4. Therefore, in the method of capturing images at a plurality of positions at the same time as in the conventional example, it is troublesome to sequentially track and monitor one work flowing on the manufacturing line.

An example of continuously monitoring one moving workpiece using a conventional example will be described with reference to FIG. FIG. 12 is a conceptual diagram showing an imaging situation of a moving work using the conventional apparatus. In FIG. 12, the work is, for example, a firework. The content recorded on the first recording device 2 is displayed as an image A.
~ D. The time from when the image of the workpiece is captured by the image capturing apparatus 1 _{1 to} when the image of the workpiece is captured by the image capturing apparatus 1 ₂ is Tα. The time from when the image of the workpiece is captured by the image capturing apparatus 1 _{2 to} when the image of the workpiece is captured by the image capturing apparatus 1 ₃ is Tβ. Time from the image of the workpiece captured in the imaging device 1 ₃ to the image of the workpiece is captured in the imaging device 1 ₄ is Tiganma. Image A is the fifth frame, image B is the 16th frame, image C is the 20th frame, and image D is the 24th frame.
There is a work image in each frame. Imaging device 1
Distance ₁ to 1 _4, i.e. the observation point P, Q, R, as S moves away, Tiarufa～tiganma increases.

Therefore, when it is desired to compare the images at the observation points P, Q, R, and S, the frames in which the images A to D are photographed are searched and printed, or they are stored in the image memory. Need to deploy. If the fireworks, which are the works, are of a continuous type, it is necessary to repeat this operation.

Since such an operation takes a long time for searching, editing, and other operations, it is not suitable for use in a manufacturing line or the like where it is important to immediately deal with an abnormality.

The present invention has been made against such a background, and it is an object of the present invention to provide a recording editing apparatus capable of monitoring a monitored object located at a chronologically distant position on the same screen. To aim. It is an object of the present invention to provide a recording editing device capable of early detection of a fault in a monitored object.

[0011]

According to a first aspect of the present invention, a plurality of image pickup devices arranged at a plurality of places for picking up an image of a subject and an output signal generated by each of the plurality of image pickup devices are individually recorded. An editing apparatus for recording provided with a recording apparatus and a second recording apparatus for editing and recording a plurality of reproduction output signals reproduced and output by the first recording apparatus into one image.

Here, the feature of the present invention resides in that means for shifting the recording start timing of the output signal generated by each of the plurality of image pickup devices for a predetermined time is provided.

Thus, for example, it is possible to focus on one and the same work flowing on the manufacturing line and trace the work in time sequence, which is useful for the supervisor to analyze the failure location. It is possible to obtain various video information.

The shift means may include means for starting recording according to a preset recording start timing. Alternatively, it is preferable that the subject is provided with a mark, and the starting means includes means for starting recording according to an output signal from a sensor that recognizes the sign.

For example, when the movement pattern of the work on the manufacturing line is constant, the recording start timing of the output signal of each image pickup device can be preset from outside by a supervisor or the like. Also, when the movement pattern of the work is indefinite, the work is marked,
Recording may be started when the work enters the field of the image pickup device by using a sensor that can recognize this sign.

It is preferable that the apparatus further comprises means for reproducing the video information recorded in the first recording device having different recording start timings with their start positions aligned.

The video information recorded by the first recording device has a different recording start position. Playback is performed by aligning the beginnings of the different video start positions, and further editing this into one image and recording it on the second recording device, so that the monitor can be displayed at different times displayed on one screen. Since the phenomena that have occurred can be monitored at the same time, it is possible for the monitor to obtain video information that is extremely useful for analyzing a failure.
