Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video monitoring device such as a plant monitoring device typically using a TV camera.

[0002]

2. Description of the Related Art Conventionally, when monitoring a wide area of a plant using a camera, the image range is widened by photographing while moving the image range of the camera or by photographing from a distance.
Further, the abnormality detection of the monitoring target device has been performed by image processing or visual recognition by a monitoring person.

[0003]

Assuming that a wide range of plant monitoring is performed by a camera using the conventional technology, the method of moving the image range of the camera cannot see portions other than the current image location. If it is desired to acquire the video information of the target monitoring target device, it is necessary to wait until the camera again captures the target monitoring target device, or to add a configuration that allows the camera to be moved from the video display device side.

[0004] In this case, it is difficult for the observer to immediately understand where the current image is taken because the image range moves and what the device is. Also, when a wide area monitoring from a distant place is performed, the video level is reduced.

[0005] Further, since the abnormality detection based on the camera image relies on the visual recognition of the observer, there is uncertainty, and it is easy to overlook small abnormalities. It has become something. In addition, there is a problem that it is difficult to understand which device is to be monitored on the monitoring screen and what the device is without prior knowledge or experience.

It is an object of the present invention to provide a video monitoring device capable of monitoring a monitoring target in a wide range and at a high altitude with a video.

[0007]

In order to achieve the above object, a video surveillance device according to the present invention comprises: a video obtaining means for obtaining a video to be monitored; And an image display device having means for moving the image portion displayed on the display unit along with the movement of the image acquisition unit.

In the present invention, when monitoring a plant over a wide range as a monitoring target, the camera image range is moved by moving the camera as image acquisition means. At this time, the position information of the image range is added to the image information and transmitted to the image display device. On the video display screen, the entire monitoring range is constantly photographed, and based on the video information and position information from the camera, real-time video display is performed by the camera only in the range where the camera is currently actually photographing. In the range other than the real-time video display, an image still received from the camera is displayed as a still image. By moving the video range by the camera, the image of the entire monitoring range is updated.
