FIG. 2A is a diagram illustrating an example of a screen display when the control object 8 is in an operation waiting state for the operator. FIG. 2B is a diagram illustrating an example of a screen display when the control object 8 is in a state other than the operation waiting state.

  As shown in FIG. 2A, on the screen of the display 11 when the control object 8 is in the operation waiting state, the operation unit 23, the device monitor screen 24, and the control object monitor screen 22 are simultaneously displayed. Is displayed. Further, as shown in FIG. 2B, when the control object 8 is in a state other than the operation waiting state, the control object monitor screen 22 is displayed in the entire area of the display 11. On the operation unit 23, various switches for operating an external control device such as a movement key arranged on the touch panel 13 are displayed. On the device monitor screen 24, state information indicating various states of the external control device 9 is displayed. On the control object monitor screen 22, an image of the control object captured by the video camera 7 is displayed.

  Next, the operation of the programmable display according to the first embodiment will be described with reference to FIG. 1 and FIG. From the control device information input from the external control device 9 via the control device connection I / F unit 5 and the operation information input from the operation control unit 6, the video processing unit 4 determines that the control object 8 is the operation unit 23. It is determined whether it is in an operation waiting state or a state other than the operation waiting state.

  When the control object 8 is in the operation waiting state, the image processing unit 4 processes the video image of the control object 8 and displays the operation unit 23, the device monitor screen 24, and the control object monitor screen 22 on the display 11. Are displayed simultaneously. That is, when the control object 8 is waiting for a control operation, the video processing unit 4 processes the video image on the screen of the display 11 so that the video image can overlap, and transmits the video information to the display unit 12.
