It is a schematic diagram which shows the web page (initial screen) displayed on the PC side first when PC4 accesses a liquid crystal projector. It is a schematic diagram which shows the example of the screen displayed on the PC4 side. It is a schematic diagram which shows the example of the screen displayed on the PC4 side. It is a schematic diagram which shows the example of the screen displayed on the PC4 side.

  Embodiments in which the present invention is applied to a liquid crystal projector will be described below with reference to the drawings.

  FIG. 1 shows the configuration of a control system for a liquid crystal projector.

  The liquid crystal projector control system includes a liquid crystal projector 1 and a control computer (PC) 4 connected to the liquid crystal projector 1 via a network 3.

  The liquid crystal projector 1 includes a server module (server means) 2. Thereby, the liquid crystal projector 1 can function as a WWW server. As the network 3, for example, a TCP / IP-based LAN is used. A WWW browser is installed on the PC 4.

  FIG. 2 shows the configuration of the liquid crystal projector 1.

  The liquid crystal projector 1 includes a server module 2 and a liquid crystal projector main body side CPU 11. The liquid crystal projector main body side CPU 11 includes a ROM 12 that stores programs and the like of the liquid crystal projector main body side CPU 11, a RAM 13 that stores necessary data, and a nonvolatile memory 14 that stores setting values and the like. A video processing unit 15 necessary for projecting an input video is connected to the liquid crystal projector main body side CPU 11.

  The server module 2 includes a server module side CPU 21, an HDD 22, and a network device 23. The server module side CPU 21 is connected to the liquid crystal projector main body side CPU 11. The server module side CPU 21 is connected to the network 3 via the network device 23. The HDD 22 stores a program of the server module side CPU 21, data necessary for providing a Web page, and the like.

  When setting the liquid crystal projector 1 from the PC 4 without starting the liquid crystal projector 1, the liquid crystal projector 1 is set in a standby state.

  When a WWW browser is activated on the PC 4 side and an IP address preset in the liquid crystal projector 1 is specified as a URL, the server module 2 sends a Web page constituting an initial screen as shown in FIG. 3 to the PC 4 side. The initial screen is displayed on the monitor of the PC 4 by the WWW browser on the PC 4 side.

  As shown in FIG. 3, the initial screen includes a key window 31 displayed on the left side of the screen. In the key window 31, keys (remote control keys) of the remote controller used in the liquid crystal projector 1 are displayed in the same form as the remote controller. The keys provided on the main body operation unit of the liquid crystal projector 1 may be displayed on the key window 31 in the same form as the main body operation unit of the liquid crystal projector 1.

  When an operator of the PC 4 wants to make various settings of the liquid crystal projector 1, he clicks a menu key among the remote control keys displayed on the initial screen.

  When the menu key is clicked, a control command corresponding to the menu key is sent to the server module 2, and a web page for causing the server module 2 to display a menu screen (setting screen) as shown in FIG. Sent to the side. As a result, a menu window 32 including a menu screen (setting screen) is displayed on the right side of the key window 31 on the monitor of the PC 4 as shown in FIG.

  In this embodiment, when the menu key of the remote control keys in the initial screen displayed on the monitor of the PC 4 is clicked, when the menu button of the remote controller of the liquid crystal projector 1 is pressed, the liquid crystal projector 1 The same menu screen as the menu screen displayed by is displayed on the monitor of the PC 4. Further, various menu screens (various setting screens) displayed when a selection item in the menu screen displayed on the monitor of the PC 4 is selected are also displayed by the liquid crystal projector 1 using the remote controller of the liquid crystal projector 1. The same screen as the menu screen (setting screen) displayed when a selection item in the menu screen is selected is displayed.

  That is, in this embodiment, the server module 2 has a Web page constituting a menu screen (setting screen) having the same hierarchical structure and the same content as a GUI (Graphical User Interface) for performing various settings on the liquid crystal projector 1 side. The function (means) provided to the PC 4 side is provided.

In the example of FIG. 4, selection items 101 to 106 in the highest hierarchy are displayed in the menu window 32. The selection items at the highest level include the following.
(1) Input
This is an item for selecting an input signal (Video, S-video, Component, PC, etc.).
(2) System (video system)
This item is used to select the video system (NTSC, PAL, XGA, etc.).
(3) Image
This is an item for selecting image settings prepared in advance so as to be suitable for various videos.
(4) Image Adjustment
This item is used to adjust the image (contrast, brightness, white balance, etc.).
(5) Screen
This is an item for setting the screen mode.
(6) Setting
This is an item for setting functions used for installation and other settings. For example, items for setting language, keystone, power management, and the like.

  For example, when the selection item “Setting” in the menu window 32 of FIG. 4 is clicked, as shown in FIG. 5, based on the Web page sent from the server module 2 corresponding thereto. In the menu window 32, selection items 111 to 116 in the next lower hierarchy corresponding to the selection item “Setting” are displayed in addition to the selection items 101 to 106 in the highest hierarchy. Further, a help window 33 is displayed below the menu screen 32, and supplementary explanations for the selection items 111 to 116 are displayed in the help window 33. However, in the example of FIG. 5, only the supplementary explanation for the selection item 111 is shown. In this example, the selection item 111 is a selection item for setting a language, and the selection item 112 is a selection item for performing automatic signal adjustment.

  When the selection item “Language” in the menu window 32 of FIG. 5 is clicked, as shown in FIG. 6, the menu window 32 is displayed based on the Web page sent from the server module 2 correspondingly. In addition to the selection items 101 to 106 of the highest hierarchy and the selection items 111 to 116 of the next lower hierarchy according to the selection item “Setting”, the selection item “language” 111 corresponds to Selection items 121 to 128 in the lowest layer are displayed, in this example, the selection item 121 is a selection item for selecting the language as English, and the selection item 122 is a selection for selecting the language as Japanese. It is an item.

  When the selection item “Japanese” in the menu window 32 of FIG. 6 is clicked, a control command corresponding to the selected item is sent to the server module 2 and Japanese is set as the language on the liquid crystal projector 1 side.

  Thus, the setting content set by the operation on the PC 4 side is stored in the nonvolatile memory 14 via the CPU 21 and the CPU 11.

  Even when the liquid crystal projector 1 is activated, various settings can be made by the PC 4 as described above. In this case, it may be possible to select whether or not to display a menu (GUI) on the projection screen projected by the liquid crystal projector 1.
