  However, in the projector as described above, the same setting item is changed regardless of the setting state. In this case, there is a possibility that inconveniences such as a change in the set value may occur regardless of items that do not require a change in the set value. Even if a desired setting change is made, if a large number of setting items are displayed on the menu screen, it is difficult for a beginner to determine which setting item should be changed. Depending on the installation state, there may be cases where there are meaningless setting items. For this reason, it is preferable that only the necessary setting items are displayed on the menu screen according to the installation state.

  It is an object of the present invention to provide an image display apparatus and a control method for the image display apparatus that can present a user with setting items that are considered to be changed according to the installation state of the apparatus.

  According to this configuration, the current setting value can be presented to the user. It is desirable that each setting item is changed to a setting value stored in the setting value storage unit along with the display of the menu screen. According to this, since each setting item is automatically changed to a setting value according to the installation state, an individual setting operation by the user is not necessary.

  In this case, it is preferable to further include a setting value change operation unit for changing the setting value of each setting item stored in the setting value storage unit.

  According to this configuration, the user can easily perform a more detailed desired setting from a normal state in which the setting value is set to a certain level.

  In this case, a selection operation unit for selecting one or more setting items from a plurality of setting items, and a selection setting for storing in a non-volatile manner one or more setting items selected by the selection operation unit for each installation state In the case where an item storage unit is further included and at least one or more setting items are stored in the selection setting item storage unit with respect to the installation state determined by the installation state determination unit, the setting item extraction unit determines the determined installation state Accordingly, it is preferable to extract one or more setting items stored in the selection setting item storage unit.

  According to this configuration, once a desired setting item is selected for an arbitrary installation state, a menu screen from which the desired setting item is automatically extracted when the apparatus is placed in the installation state again. Is displayed. That is, since the menu screen once customized is automatically displayed from the next time, it is convenient.

  In this case, for each installation state, the system further includes an operation number storage unit that nonvolatilely stores the number of times the setting value of each setting item has been changed by the setting value change operation unit, and the operation number storage unit includes a setting value for each setting item. When the number of times of change is stored, the menu screen display unit displays each setting item in the ascending / descending order according to the number of times stored in the operation number storage unit on the menu screen according to each installation state. It is preferable.

  According to this configuration, since the setting items that the user frequently operates are displayed at the top, a menu screen that is convenient for the user can be displayed.

  In this case, the apparatus further includes a mode switching unit that switches the mode to one of the installation modes corresponding to each installation state, and the installation state determination unit determines the installation state according to the mode switched by the mode switching unit. It is preferable.

  According to this configuration, for example, when the installation state of the apparatus is changed not for displaying an image, such as when replacing or repairing a battery, but for other reasons, the installation state is not erroneously determined. . Further, the installation state can be determined based on the timing desired by the user.

  In this case, it is preferable to further include a state detection unit that detects each installation state, and the installation state determination unit determines the installation state according to the detection result of the state detection unit.

  According to this configuration, there is no need for trouble such as mode switching according to the installation state.

  According to this configuration, the display unit preferably displays the menu screen when the installation state determined by the installation state determination unit changes.

  According to this configuration, it is possible to quickly present to the user setting items that preferably change the setting value according to the installation state as the installation state changes. Therefore, it is possible to prevent the user from seeing a large number of setting items and performing complicated operations to change the settings.
