Computer programing for the navigation image analysis was made. We can get the information about that when we use the navigation system during the operation to check the image outputted from navigation system. But this method took a lot of time. So we tried to make such a computer program to analyze the navigation usage timing during the operation. We think that it is useful also as a tool of an operation educational program for the way person of an initial level operator.
