  The storage unit 21 includes a non-volatile memory such as a mask ROM (Read Only Memory), a flash memory, or an FeRAM (Ferroelectric RAM). The storage unit 21 stores various control programs and various data for controlling the operation of the projector 1.

  The data stored in the storage unit 21 includes a wording database DB that stores all words included in a message image or menu image displayed by the projector 1 as a character code string (character string data), and these words as images. For display, a font file FF or the like for storing bitmap data (font data) corresponding to each character code is included. The wording database DB corresponds to the character string data group of the present invention, and the font file FF corresponds to the font data group of the present invention.

  The operation unit 22 and the remote controller RC are provided with a plurality of operation buttons for giving various instructions to the projector 1. The operation buttons of the operation unit 22 and the remote controller RC include a “power button” for turning on / off the power, a “menu button” for projecting an environment setting menu as one of setting images, and a cursor on the menu. There are a “cursor button” for selecting an item by moving it, a “decision button” for determining an item selected on the menu, and the like. When the user operates various operation buttons of the operation unit 22, the operation unit 22 outputs an operation signal corresponding to the operation content of the user to the control unit 20. When the user operates various operation buttons of the remote controller RC, the remote controller RC generates an infrared operation signal corresponding to the user's operation content, and the operation signal receiving unit 23 receives this and transmits it to the control unit 20.

  The interface unit 24 includes various device controllers such as a USB (Universal Serial Bus) controller and a PCI (Peripheral Component Interconnect) controller, and inputs and outputs data to and from an external device. The interface unit 24 is provided with a card slot and a USB port (both not shown) for connecting an external device, and a communication unit 25 is connected to the card slot of this embodiment.

  The communication unit 25 is a network card that can be connected to a network NW such as a LAN (Local Area Network), and performs transmission / reception of commands related to network connection, reception of image signals, and the like based on instructions from the control unit 20. Can do. When the communication unit 25 receives an image signal via the network NW, the image signal is output to the image signal processing unit 27.

  The image signal input unit 26 includes various connection terminals for connecting to an external image supply device (not shown) such as a PC (personal computer) or a video reproduction device via a cable. An image signal is input. The image signal input unit 26 converts the image signal into an image signal in a format that can be processed by the image signal processing unit 27, and outputs the image signal to the image signal processing unit 27.

  The image signal processing unit 27 is an image processor, and performs signal processing on an image signal input via the image signal input unit 26 or the interface unit 24 in accordance with an instruction from the control unit 20, and the liquid crystal light valves 12R, 12G. , 12B, image data for defining the drive voltage applied to each pixel is generated. Further, when image data representing a menu image or the like is input from the control unit 20, the image signal processing unit 27 performs processing for superimposing the image represented by the image data on the input image or displaying the image on the entire screen. Etc. The image signal processing unit 27 outputs the image data subjected to various processes to the light valve driving unit 28.

  The light valve driving unit 28 drives the three liquid crystal light valves 12R, 12G, and 12B based on the image data input from the image signal processing unit 27. As a result, an image (image light) corresponding to the image data is projected from the image projection unit 10.

  As described above, the projector 1 can project an input image based on an image signal input from the outside via the input terminal CN or the communication unit 25, and also allows the user to make various settings of the projector 1 (for example, network settings). When performing (setting), various menu images (setting images) can be projected, and when notifying the user of an error message or the like, a message image can be projected.

  2-4 is explanatory drawing which shows an example of a setting image. When the user operates a menu key provided on the operation unit 22 or the remote controller RC, the control unit 20 generates image data representing a setting image Gm (environment setting menu) as shown in FIG. Then, the setting image Gm is displayed superimposed on the input image Gi.

  As shown in FIG. 2, the setting image Gm has a main menu in which menu items to be set (“image quality adjustment”, “video”, “setting”, “extended setting”, “network”, etc.) are arranged to be selectable. It includes Gm1, a submenu Gm2 for displaying and changing setting values related to the item selected in the main menu Gm1, and an operation guide Gm3 for guiding menu operations. When the user operates the cursor key to select a desired menu item from the main menu Gm1, and then operates the enter key, the control unit 20 displays the setting items, setting values, etc. relating to the selected menu item in the submenu Gm2. And the user is allowed to change the setting value. For example, when “image quality adjustment” in the main menu Gm1 is selected, the control unit 20 displays a submenu Gm2 (see FIG. 2) in which the brightness and contrast of the input image can be adjusted. When “SETTING” is selected, a submenu Gm2 for correcting trapezoidal distortion and switching the luminance of the light source unit 11 is displayed. Although not shown in the figure, the submenu Gm2 when “Extended Settings” in the main menu is selected includes a menu item for selecting “Language”. A desired language can be selected from 20 languages such as Japanese, English, French, German, etc.

  When “network” is selected from the menu items of the main menu Gm1, the control unit 20 generates image data representing a setting image Gn (network setting menu) as shown in FIG. The image data is output to the image signal processing unit 27, and the setting image Gn is displayed on the entire screen (entire projection image).

  As shown in FIG. 3, the setting image Gn is selected by a main menu Gn1 in which menu items relating to the network (“basic setting”, “wireless LAN”, “security”, etc.) are selectably arranged, and the main menu Gn1. It includes a sub menu Gn2 for displaying and changing setting values related to the items and an operation guide Gn3 for guiding menu operations.

Here, when a language other than Japanese is selected in the “extended setting” of the configuration menu (setting image Gm) shown in FIG. 2, all menu images and message images including the setting images Gm and Gn are displayed. Most of the words included are written in the selected language. For example, when the user performs an operation to display the network setting menu (setting image Gn) in a state where “English” is selected as “Language”, the control unit 20 includes all of the images included in the image as shown in FIG. The setting image Gn in which the words (title, item name, etc.) are written in English is generated and displayed.
The contents set in various menus (setting images Gm, Gn, etc.) are stored in the storage unit 21.

Here, an operation when the control unit 20 generates the setting image will be described.
FIG. 5 is an explanatory diagram showing the configuration of a program that causes the control unit 20 to generate a setting image.
As shown in FIG. 5, the program that causes the control unit 20 to generate a setting image has a three-layer structure, and a utility layer UT that generates a word resource (image data representing a word) (hereinafter also simply referred to as a utility UT). , A resource manager layer RM (hereinafter also simply referred to as resource manager RM) that manages the wording resources generated in the utility layer UT, and an application layer AP (hereinafter simply referred to as application AP) that generates a setting image using the generated wording resources. Or the like).

  The generation of the setting image is led by the application AP. In generating the setting image, the application AP requests the resource manager RM for a wording resource necessary for generating the setting image. Specifically, the application AP notifies the resource manager RM of an index that can specify a required wording and its display color and display size.

  The resource manager RM is a wording resource in which various combinations of a plurality of keywords representing various words, a plurality of color information representing the display color of the wording, and a plurality of size information representing the display size of the wording are associated with one index, respectively. A table RT is provided. For this reason, when the index is notified from the application AP, the resource manager RM identifies the keyword, color information, and size information represented by the index by referring to the wording resource table RT, and this information (keyword, Color information and size information) are notified to the utility UT, and language information representing the language (setting language) set in the environment setting menu (setting image Gm) is read from the storage unit 21 and notified to the utility UT.

  When the utility UT receives the notification, the utility UT refers to the wording database DB and acquires character string data representing the designated wording. Here, the character string data is a character code string in which the character codes of characters constituting the wording are enumerated.

FIG. 6 is an explanatory diagram for explaining the wording database DB.
As shown in FIG. 6, in the wording database DB, character string data representing all words used in setting images, message images, and the like correspond to keywords (ID_YES, ID_NO, etc.) that can specify words for each language. Attached and stored. That is, the wording database is a two-dimensional table that can specify character string data representing a specified wording from two pieces of information, that is, a keyword and language information.

  Returning to FIG. 5, the utility UT acquires character string data specified by the keyword and language information notified from the resource manager RM from the wording database DB. After that, the utility UT acquires font data (bitmap data) of each character from the font file FF based on the character code included in the acquired character string data, and further, specified using this font data. Image data (word resource) in which a word is drawn with a specified display color or display size is generated. The utility UT stores the generated word resource in the storage unit 21 and outputs a pointer (address) indicating an area in which the word resource is stored to the resource manager RM.

The resource manager RM stores the pointer input from the utility UT in the wording resource table RT in association with the index notified from the application AP, and notifies the application AP of the pointer.
The wording resource table RT can store an index notified from the application AP in association with a pointer input from the utility in addition to the keyword, color information, and size information described above. For this reason, when the resource manager RM receives a request for a wording resource from the application AP, the resource manager RM refers to the wording resource table RT to check whether a pointer to the wording resource is stored in the specified index. If not, the utility UT is caused to generate a wording resource as described above. On the other hand, when the pointer is stored in the designated index, that is, when the requested wording resource has been generated by the utility UT in the past, the wording resource is not generated again by the utility UT. The application AP is notified of the pointer stored in the table RT.

  When the application AP receives a pointer from the resource manager RM, the application AP refers to the pointer and acquires the wording resource (image data). The application AP obtains all the wording resources necessary for composing the setting image by repeating the above processing for all the words included in the setting image, arranges them in a predetermined layout, and arranges the setting image. Generate image data to represent. When the control unit 20 outputs the image data to the image signal processing unit 27, the generated setting image is projected from the image projection unit 10.

  Of the elements constituting the setting image, resources other than the word (for example, a frame surrounding the word) are stored as image data in the storage unit 21, and the application AP is similar to the case of the word resource. By notifying the resource manager RM of an index that can identify the resource (image data), a pointer indicating the storage area of the resource can be acquired.

  In the present embodiment, when the application AP notifies the resource manager RM of the index, the control unit 20 that operates according to the application AP corresponds to the word designation unit of the present invention, and the utility UT generates the word resource. In addition, the control unit 20 that operates according to the utility UT corresponds to the image forming means of the present invention.

As described above, according to the projector 1 of the present embodiment, the following effects can be obtained.
(1) According to the projector 1 of the present embodiment, since the control unit 20 is configured to form an image including a word based on the character string data including the character code and the font data, the wording is added. When making changes, it is only necessary to add or change (edit) character string data. For this reason, it is not necessary to previously create and store necessary text as image data, and it is possible to easily add or change the text. Also, when changing the font of a character, it is only necessary to replace the font file.

  (2) According to the projector 1 of the present embodiment, the control unit 20 forms an image including words based on the character string data including the character code and the font data. When the number of words to be stored increases along with the above, character string data is added and font data may be added as necessary. On the other hand, if the wording is stored in advance as image data, image data whose data size is larger than that of the character string data is added as the wording increases. Easy to be. That is, according to the present embodiment, it is possible to suppress the compression of the storage unit 21 when the number of words to be stored increases compared to the case where the words are stored in advance as image data. In particular, the greater the number of words that can be expressed in a predetermined font file, the more prominent the advantage of this embodiment is.

  Note that the font file FF stored in the storage unit 21 does not need to store font data corresponding to all character codes, only font data of character codes included in character string data in the wording database DB. As long as it has. That is, it is possible to thin out the font data of the character code that is not used in the menu image or the message image from the font file FF, thereby reducing the data size of the font file FF and storing it in the storage unit 21. Capacity can be saved.

(Second Embodiment)
Hereinafter, a display device according to a second embodiment of the present invention will be described with reference to the drawings.
In the first embodiment, the wording database DB stored in the storage unit 21 stores character string data that can be specified by keywords and language information, but stores additional information in addition to the character string data. By doing so, it is possible to generate a wording resource in which the wording is controlled in various ways.

  In the wording database DB of this embodiment, line feed information, color information, size information, and the like are added as additional information for each character string data. It is possible to make the character (part) have an attribute different from the color and size designated by the application AP.

  For example, the application AP inquires whether or not to end the presentation using network communication (if the setting language is Japanese, “Do you want to end the network presentation?”, Or if the setting language is English) When “Do you want to Exit the Network Presentation?” Is displayed on the screen, the application AP notifies the resource manager RM of an index that can identify these words. Upon receiving this index, the resource manager RM outputs a keyword (ID_MES_NPEND) representing the wording, language information, and the like to the utility UT.

  7 and 10 are diagrams showing character string data stored in the wording database DB in association with the keyword ID_MES_NPEND. FIGS. 8 and 11 are character string data shown in FIGS. 7 and 10, respectively. It is explanatory drawing which shows the additional information added to. FIGS. 9 and 12 are explanatory diagrams showing images generated based on the character string data and the additional information.

  In the wording database DB according to the present embodiment, the characters “Do you want to end the network presentation \ 0? \ 0” as shown in FIG. 7 as data represented by Japanese as the set language and ID_MES_NPEND as the keyword. Along with the column data SJ, additional information as shown in FIG. 8 is included. '\ 0' in the character string data SJ is a control character (delimiter character as delimiter data) indicating a delimiter of the wording, and the wording is broken at the position where it is inserted, or the attribute of the character is switched. It shows that That is, the wording is divided into a plurality of parts (characters) by the delimiter character, and can have a different aspect for each part. Note that “\” included in “\ 0” is an escape sequence, and “\ 0” is represented by one character code.

  As shown in FIG. 8, the additional information added to the character string data SJ includes delimiter information indicating the delimiter position (number of characters from the beginning) for each word delimiter, and whether to perform a line break at the delimiter position. Line break information indicating whether or not, color information indicating a display color from the break position, and size information indicating a character size from the break position are included.

  In this case, the first break of the wording is the beginning (0th character) of the character string data SJ, and the additional information includes line feed information indicating that a line break is to be performed at this position (immediately before the first character). (In this embodiment, a line feed is always performed at the beginning of the wording). Further, the additional information includes color information for changing the character color to red from the first break of the wording and size information for setting the character size to the default (character size specified by the resource manager RM).

  The second delimiter of the wording is the 17th character of the character string data SJ (the character next to the first delimiter '\ 0'), and the additional information includes a line break at this position (immediately before the 17th character). Includes line break information indicating that no character is to be performed, color information for changing the character color from this character to red, and size information for increasing (emphasizing) the character size from this character.

  The third delimiter of the wording is the 20th character of the character string data SJ (the character following the second delimiter character '\ 0'), and the additional information includes a line break at this position (immediately before the 20th character). Line break information indicating that no text is to be displayed, color information for making the character color from this character the default (color specified by resource manager RM), and size information for making the character size the default from this character ing. By giving a value (for example, 0) smaller than the previous delimiter information as the fourth delimiter information, it indicates that the wording ends at the fourth delimiter position.

The utility UT generates image data (word resource) representing the image GJ as shown in FIG. 9 by referring to the additional information as described above. That is, “End Network Presentation” from the beginning of the wording (1st break) to just before the 3rd break is displayed in red, and “Do you want to do?” After the 3rd break is the default color (for example, black) Is displayed. In addition, “end” from the second segment to the third segment is displayed in a size larger than the default character size. Note that the underline shown in the figure is added to explain the display color of the character and is not included in the actual wording resource.
As in the first embodiment, the utility UT notifies the resource manager RM of the pointer storing this wording resource.

  On the other hand, in the wording database DB, character string data “Do you want to \ 0Exit \ 0the Network Presentation \ 0? \ 0” as shown in FIG. 10 is used as data represented by the set language as English and the keyword as ID_MES_NPEND. Along with SE, additional information as shown in FIG. 11 is included.

  As shown in FIG. 11, the first delimiter of the wording is the beginning (0th character) of the character string data SE, and additional information includes line feed information indicating that a line break is to be performed at this position, and characters from this position. Color information that sets the color as the default color and size information that sets the character size as the default are included.

  The second delimiter of the wording is the 16th character of the character string data SE (the character following the first delimiter character '\ 0'), and the additional information indicates a line break indicating that no line break is to be performed at this position. Information, color information for changing the character color from this character to red, and size information for increasing (emphasizing) the character size from this character are included.

  The third delimiter of the wording is the 21st character of the character string data SE (the character following the second delimiter character '\ 0'), and the additional information includes line break information indicating that a line break is to be performed at this position. , Color information for making the character color from this character red, and size information for making the character size the default from this character are included.

  The fourth delimiter of the wording is the 46th character of the character string data SE (the character next to the third delimiter character “\ 0”), and the additional information indicates a line break indicating that no line break is performed at this position. Information, color information for making the character color from this character the default color, and size information for making the character size from this character the default are included. Further, the fifth delimiter information has a smaller value (for example, 0) than the previous delimiter information.

  The utility UT generates image data (word resource) representing the image GE as shown in FIG. 12 by referring to the additional information as described above. That is, "Do you want to" from the beginning of the wording (1st break) to just before the 2nd break and "?" After the 4th break are displayed in the default color, from the 2nd break to just before the 4th break “Exit the Network Presentation” is displayed in red. In addition, “Exit” from the second segment to immediately before the third segment is displayed in a size larger than the default character size, and the third and subsequent segments are displayed with line feeds.

As described above, according to the projector 1 of the present embodiment, in addition to the effects of the first embodiment, the following effects can be obtained.
(1) According to the projector 1 of the present embodiment, the additional information representing the form of the wording is stored in the wording database DB, and the control unit 20 forms an image including the wording based on the additional information. Therefore, the wording can be displayed in various ways.

  (2) According to the projector 1 of the present embodiment, since the character string data includes the delimiter character “\ 0” representing the change position of the aspect, the control unit 20 determines the position and range for changing the aspect. It becomes possible to specify easily.
