In this embodiment, the operator operates the operating means 103, and the state setting means 102 stores the display density values of the operable buttons and the display density values which cannot be operated in the storage means 101. It is assumed that they are stored with different values.

As shown in FIG. 7, in step 7, the buttons that can be operated by the operator from the operation unit 103 and the buttons that cannot be operated are set to different display density values in the storage unit 101. Is determined. Here, since both are stored in the storage unit 101 as different display density values, the process proceeds to the next step.

In step 8, the button state determination means 10
From 9, all button states after the state change are obtained. The button state after the state change means that the button is
The information indicates whether the operation is possible or impossible.

In step 9, the display state determination means 104
As a result, the button state of the button after the change obtained in step 8 is compared with the display state of the button displayed on the display unit 105.

In step 10, as a result of the comparison in step 9, it is determined whether or not the currently displayed button state needs to be changed. If the button needs to be changed, the process proceeds to step 11.

In step 11, it is determined whether or not the button that needs to be changed is currently in a display state. If it is the current display state, the process proceeds to step 12, and the button is changed to the display density stored in the storage unit 101.

The processing after step 9 is repeated by the number of buttons installed in the remote control application.
