<p>PROBLEM TO BE SOLVED: To grasp information concerning an alarm accurately by making the operator wear a small spectacle type display section for displaying an image with information concerning to an indicator or monitor information of other operators. SOLUTION: When an operator monitors an alarm information, a small camera 14 takes in the actual image 2-1 (including a label number 2-3 and a bright pixel 2-2 transmitting an alarm) of a display within the range being monitored by the operator. The actual image 2-1 is delivered to an image processing computer 15 which generates a processed screen 2-4 when a pixel having brightness of a specified level or above is extracted from the actual image 2-1 picked up by means of the small camera 14. The content of a character in an alarm window corresponding to a light emitting point 2-5 is not recognized up to that moment but an alarm window estimated to be the most interesting one for the operator can be extracted by extracting a light emitting point closest to the center of the screen 2-4. Consequently, information concerning to alarm can be grasped accurately and the factor of a grasped failure can be transmitted to other operator.</p> |
