であったが、変化する被写体を明確に撮像することは出
来なかった。Conventionally, in surveillance video recording devices installed in banks and other facilities to prevent theft, the video camera is fixed, so if the video range is wide, it is possible to record changes in objects that fall within that wide video range over a long period of time. However, it was not possible to clearly capture a changing subject.

装置を提供することを目的としている。This invention was made in order to eliminate the drawbacks of the conventional ones as described above. It detects small changes in the subject within the video range and automatically zooms the video camera or changes its direction accordingly. It is an object of the present invention to provide a surveillance video recording device that can clearly image and record a subject by changing the subject.
以下、この発明の一実施例を図について説明する。An embodiment of the present invention will be described below with reference to the drawings.

する駆動回路である。The drawing shows a surveillance video recording device according to an embodiment of the present invention. In the drawing, (1) is a video camera equipped with a zoom function and whose direction can be changed; Magnetic recording and reproducing device that can record vertically, (3)
1 is a field memory device that stores a certain field or frame of the video signal from the video camera (1); f51, a video buffer device that captures the video signal of
is a comparison device that compares the video signal from the field memory device (3) and the video signal from the video buffer device (4), and (6) is a change when the comparison device (5) detects a difference between the two video signals. This is a drive circuit that changes the direction of the video camera (1) or adjusts its zoom toward the subject where the video camera (1) has occurred.

できる。The output of the video camera (1) is recorded in a magnetic recording and reproducing device (2) capable of recording over a long period of time, and the video signal of a certain field or frame of the video signal from the video camera (1) is stored in a field memory device. (3)
memorize it. On the other hand, the video buffer device (4) receives the output video signal from the video camera (1) as it is, or receives signals for each predetermined field of the video signal.
This video signal is compared with the video signal of the field memory device (3) by a comparator (5). If the subject moves, there will be a difference between the two video signal numbers, and the drive circuit (6) will respond to the output of the comparator (5) to change the direction of the video camera (1) or Adjust the zoom. Therefore, the video camera (1) tracks the moving subject, and even if the subject moves or changes, it is possible to clearly image and record the subject.
以上において、上記フィールドメモリ装置（３）のメモ
リの内容は必要に応じて変更することができ、例えは本
装置を銀行の夜間監視用に用いる場合には一度夜に記憶
をさせれば次の朝までそのままとしておくことができ、
一方晶間の監視用に用いる場合には、１時間毎等の一定
周期で内容を変更するようにすることもできる。In the above, the memory contents of the field memory device (3) can be changed as necessary. For example, if this device is used for night surveillance of a bank, once it is stored at night, the contents of the memory can be changed as needed. You can leave it as is until morning,
On the other hand, when used for monitoring crystal rooms, the contents may be changed at regular intervals such as every hour.
なお、この発明はビデオカメラの制御のみでなく、産業
用ロボット及び無人カーなどの自動制御にも適用するこ
とが可能である。Note that the present invention can be applied not only to the control of video cameras, but also to the automatic control of industrial robots, unmanned cars, and the like.
