DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of the overall configuration showing one embodiment of the present invention. In the figure, 1 is a monitoring target, 2 is a normal monitoring device, 3 is an emergency monitoring device, 4a to 4d are indicators, 5a to 5d are operating devices, and 6a to 6d are speakers. The difference from the conventional example is that the display devices 4a to 4d and the operating device 5
a to 5d and speakers 6a to 6d are all connected to both the normal monitoring device 2 and the emergency monitoring device 3, respectively. During normal operation, the display units 4a to 4d share and display information output from the monitoring device 2 during normal operation, and the operating units 5a to 5
In step d, the operator operates the information displayed on the corresponding display. 18 is an operator; 17 is a hat worn by the operator with a target mark 19 attached thereto; A camera head 15 including a lens 16 is installed at a high place near the ceiling of the operation room, as shown in FIG. 2, and photographs the state of the operation room including the target mark 19. The camera controller 14 takes out images from the camera head 15 at regular intervals. The obtained image signal is sent to the image processing device 10, and the image processing device 10 processes the image signal to detect the position and direction of the target mark 19. Reference numeral 7 denotes a direct-view determination device that determines the closest indicator that the operator 18 is directly viewing or can directly view, based on the position and direction of the target mark 19. The output of this direct visibility discrimination device 7 is coupled to the emergency monitoring device 3, and when an emergency situation occurs, the emergency monitoring device 3 selects a display that is determined to be a display device that can be viewed directly by this direct visibility discrimination device 7. Select to display emergency information on it. Therefore, in the event of an emergency, the emergency information is displayed on the nearest display that the operator 18 is directly viewing or can see directly, and the operator 18 does not need to move or only has to travel a short distance.

FIG. 3 is a block diagram of an image processing device and a direct vision discrimination device according to the present invention. The image processing device 10 includes a frame memory 11, a target mark image processor 12, and a target mark position/direction detection processor 13, and the frame memory 11 stores one scene of an obtained image. The target mark image processor 12 uses the frame memory 1
1 and extracts the address of the target mark on the frame. The target mark position/direction detection processor 13 detects this target mark 19.
The position and direction of the target mark 19 are determined from the address on the frame. The direct vision discriminator 7 includes an operating room coordinate system converter 8 and a direct vision display discriminator 9, and the operating room coordinate system converter 8 is supplied from the target mark position/direction detection processor 13 of the image processing device 10. The position and direction of the target mark 19 are converted to the position and direction on the operation room coordinate system. Reference numeral 9 denotes a direct-view display discriminator that determines the closest display that the operator is directly viewing or can directly view from the position and direction on the operating room coordinate system. Next, the operation of this device will be explained.

For example, when a single operator performs monitoring work at night, he or she sequentially inspects the normal displays 4a to 4d and performs necessary operations. Assume that the operator 18 is now looking at the display 4c. On the other hand, at this time, the target mark on the hat of the operator 18 is the camera head 15 including the lens 16.
The image is photographed together with the environment of the operating room, and is sent as a signal to the image processing device 10 by the camera controller 14. The image processing device 10 processes the image signal to detect the position and direction of the target mark 19, and uses the direct-view determining device 7 to determine the closest display that the operator 18 is directly viewing or can directly view. If an emergency situation occurs here, the emergency monitoring device 3 uses the display 4c that the operator 18 is looking at at that time based on the judgment of the direct visual discrimination device 7.
is selected and an output signal is supplied to it, so emergency information is displayed on the display 4c, and corresponding operations can be performed using the operating device 5c. In this way operator 18
The operator can read emergency information from the display he was observing at the time, or from a display located very close to him, and perform operations accordingly, without moving.
