Description

  The present invention relates to a display device, a content display program, and a recording medium for displaying content whose display layout is defined in advance on a predetermined display.

  So-called portable information terminal devices such as cellular phones are equipped with more advanced functions than ever before. As one of the functions, for example, there is a function of browsing a web page. In old mobile phones, the display capacity of web pages was limited due to the small screen. Due to this restriction, a normal web page viewed on a personal computer cannot be viewed on a mobile phone as it is. For this reason, it was common for old mobile phones to browse specially prepared web pages with a simpler display layout.

  However, in recent years, mobile phones are also being equipped with a function that allows normal web pages to be browsed as they are. This function is realized by a so-called full browser (trademark registration pending). The full browser has basically the same function as a normal web browser installed in a personal computer. Therefore, the web page displayed on the screen of the personal computer can be displayed on the screen of the mobile phone as it is.

  However, the screen of a mobile phone is generally smaller than the screen of a personal computer. Therefore, the full browser of the mobile phone has a feature that the display layout is changed to a simplified one so that the web page to be displayed does not need to be horizontally scrolled. Thereby, the web page according to the screen characteristic is displayed on the screen of the mobile phone having a small display capability.

  Also, Patent Document 1 proposes a portable terminal having a new configuration and having a so-called projector function. In Patent Document 1, a display for image display, a projector for image projection, and a control means for controlling the display and the projector are housed in a hand-held housing, and at least an image displayed on the display is displayed. A portable terminal is disclosed, which is partly configured to be able to be enlarged and projected to the outside of the housing via the projector.

Also, Patent Document 2 proposes a communication device that can display an image displayed on the screen of a mobile phone in a larger size. Patent Document 2 discloses a communication unit that transmits / receives a mobile phone service, an operation unit, a call unit that processes voice, a large screen display unit that is exceptionally large compared to a mobile phone, and a control that controls the display unit. And a communication device capable of receiving a cellular phone service.
Japanese Patent Laid-Open No. 2001-21992 (released on January 26, 2001) JP 2002-281124 A (released on September 27, 2002)

  However, the above-described conventional technique has a problem in that an optimal display layout screen corresponding to the display capability of the display cannot be displayed.

  In the portable terminal of Patent Document 1, a screen having the same display layout is displayed on a display for image display and a projector for image projection. Therefore, for example, when an electronic book having a magazine size and display layout is projected onto a projector, the screen is also displayed on an image display. For this reason, although the user can satisfactorily browse the electronic book with the projector, he / she is dissatisfied because he / she browses the hard-to-read electronic book with the display at hand.

  On the other hand, the communication device of Patent Document 2 is positioned as a device that can receive a mobile phone service, and the display layout of the received image is unconditionally changed and displayed on the large screen display unit. With this configuration, when an image with a more complicated display layout that is not intended for a cellular phone service is received, the display layout of the image may be unconditionally changed. That is, Patent Document 2 does not disclose the technical idea of flexibly changing the image display layout in accordance with the display capability of the display.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a display device, a content display method, a content display program, and a recording device that display a screen having an optimal display layout corresponding to the display capability of the display.

In the display device according to the present invention,
The display means is
In the display layout defined in advance for the content, it is preferable that the background colors of a plurality of objects defined to be displayed on the same line are displayed in the same color respectively. The display layout defines that a plurality of objects are displayed on the same line. The display device of this configuration redefines a predetermined display layout to a simpler display layout, and displays a plurality of objects on the display based on the redefined display layout. Here, the display means displays the background colors of these objects displayed based on the redefined display layout in the same color. For example, among the objects to be displayed in one column, the same background color defined to be displayed in the same row in the original display layout is displayed in the same light blue color. Accordingly, the user can easily confirm the original display layout by confirming the background color of each object displayed on the display.

In the display device according to the present invention,
The display means is
It is preferable that the background colors of a plurality of objects displayed in succession included in the content are changed and displayed.

  According to said structure, a display means displays the background color of the several object continuously displayed on a display mutually differently. As a result, the display of the plurality of objects displayed by the simpler display layout is sharpened, and the user can be prevented from monotonously feeling the plurality of objects displayed continuously.

In the display device according to the present invention,
The display means is
Based on the simpler display layout selected by the layout selection means, the content is displayed on the first display,
It is preferable to display the content on a second display having at least one of resolution and size larger than that of the first display, based on the more complicated display layout selected by the layout selection unit.

  According to said structure, a display means displays a content on a 1st display and a 2nd display. The second display is at least one of resolution and size larger than the first display. In other words, the display means displays the same content on two displays having different amounts of information that can be displayed. Here, the display means displays the content of a simpler display layout on the first display. On the other hand, content with a more complicated display layout is displayed on the second display.

  Accordingly, the display device has an effect of preventing a screen with a simpler display layout displayed on the first display from being displayed on the second display having higher display capability.

  According to said structure, a display apparatus displays the location corresponding to the screen displayed on a 1st display among the screens displayed on a 2nd display by a state different from normal. For example, a frame line is displayed in the frame of the corresponding location. Alternatively, an underline is displayed on the object included in the corresponding portion. As a result, the display device has an effect of allowing the user to easily check where the screen displayed on the first display is on the screen displayed on the second display.

In the display device according to the present invention,
The display means is
Of the content, it is preferable that a portion that is determined not to be displayed on the second display is displayed on the first display while not displayed on the second display.

  According to said structure, a display apparatus displays the part previously determined not to display on a 2nd display among contents on a 1st display. On the other hand, this object is not displayed on the second display. As described above, the display capability of the second display is greater than the display capability of the first display. Therefore, the display means does not display objects that are determined not to be displayed in advance on a display that can display more information.

  Some objects that are determined not to be displayed in advance are preferably not viewed by anyone other than themselves. Thus, in the display device, when the user is looking at the first display and a person other than the user is looking at the second display, the user can confirm this object, while preventing a person other than the user from seeing the object. There is an effect that can be done.

In the display device according to the present invention,
The display means is
It is preferable that predetermined text included in the content, which is determined not to be displayed on the second display, is displayed on the first display, but not displayed on the second display.

  According to said structure, a display apparatus does not display the text decided not to display on a 2nd display beforehand on a 2nd display. On the other hand, this text is displayed on the first display. This text is preferably not seen by anyone other than yourself, for example. That is, the display device does not display this text on a display that can display more information. Thereby, for example, when the user looks at the first display and a person other than the user is looking at the second display, the user can confirm this text, while a person other than the user can be prevented from seeing this text.

In the display device according to the present invention,
The display means is
It is preferable that the specific image included in the content is displayed on the second display without being displayed on the first display.

  According to said structure, a display apparatus displays the specific image contained in the content on a 2nd display. However, this image is not displayed on the first display. That is, an image is not displayed on a display with less information that can be displayed. Accordingly, the display device can prevent excessive information from being displayed on the first display. On the other hand, the user can surely confirm this image on the second display.

In the display device according to the present invention,
The display means is
It is preferable to display an explanatory note explaining the specific image not displayed on the first display on the first display.

  According to said structure, a display apparatus displays the explanatory note explaining the specific image which is not displayed on a 1st display on a 1st display. Thereby, for example, the user can see the explanatory text displayed on the first display. On the other hand, a person watching the second display cannot see the explanatory text displayed on the first display. Instead, you can see the image that is displayed on the second display, explained by this description. Thereby, for example, the user can use the display device as a presentation tool.

  The display device may be realized by a computer. In this case, a content display program for realizing the display device in the computer by operating the computer as each of the above means, and a computer-readable recording medium on which the content display program is recorded also fall within the scope of the present invention.

  As described above, the display device according to the present invention includes a layout selection unit that selects a display layout corresponding to at least one of the display resolution and the display area size, and thus is optimal for the display capability of the display. The effect is that a screen with a proper display layout can be displayed.

  An embodiment of the present invention will be described below with reference to FIGS.

(Outline of the information terminal device 1)
First, the outline | summary of the information terminal device 1 which concerns on this embodiment is demonstrated. FIG. 1 is a block diagram showing a configuration of an information terminal device 1 according to an embodiment of the present invention. The information terminal device 1 shown in FIG. 1 displays predetermined content represented by digital data in a predetermined display area on a predetermined display. For example, an electronic book or a web page is displayed in one window in the liquid crystal display. In this example, an electronic book or a web page corresponds to the content. The liquid crystal display corresponds to a predetermined display. One window corresponds to a predetermined display area on the display.

  The content displayed on the display by the information terminal device 1 includes a plurality of objects. For example, an image and text are included as a plurality of objects. This image may be either a still image or a moving image. In this content, a display layout applied when these objects are displayed on a display is defined in advance. This display layout defines, for example, that images and text are displayed in a matrix on the display. Layout data representing an object display layout is included in advance in content data representing content.

  The information terminal device 1 displays a plurality of objects in a predetermined display area on the display based on the display layout defined for the objects. The information terminal device 1 redefines a predefined display layout to an optimal display layout according to the display capability of the display. Specifically, the information terminal device 1 acquires the display resolution of the display and the size of a predetermined display area on the display before displaying the content on the display. The information terminal device 1 compares the acquired resolution and the size of the display area with a predetermined reference value. At this time, when at least one of the resolution of the display and the size of the display area is different from the predetermined reference value, the information terminal device 1 optimizes the predetermined display layout for a plurality of objects to the display. Redefine what can be displayed.

  The information terminal device 1 can redefine a more complicated display layout to a simpler display layout. For example, a display layout that is defined to display a plurality of objects by a matrix can be redefined as a display layout that is displayed by one row. At this time, the information terminal device 1 displays a plurality of objects included in the content in a predetermined display area on the display based on the redefined display layout. For example, a plurality of objects defined to be displayed by a matrix are displayed on the display by one line.

  The resolution of the display and the size of the predetermined display area of the display are predetermined display characteristics that reflect the amount of information that can be displayed on the display. That is, the information terminal device 1 uses a plurality of objects based on such display characteristics. Redefine the display layout to apply when displaying on the display. Thereby, the information terminal device 1 can display the content of the optimal display layout corresponding to the information display capability of the display.

(Details of information terminal device 1)
Details of the information terminal device 1 will be described below with reference to FIG. According to this figure, the information terminal device 1 includes an operation unit 2, a content acquisition unit 3, a content database 4, a data reading unit 5, a layout redefinition unit 6, a display unit 7, a built-in display 8, a projection unit 9, a projector screen. 10, a display information acquisition unit 11, and a distance measurement unit 12.

(Operation unit 2)
The operation unit 2 receives an operation of the information terminal device 1 by the user. The operation unit 2 outputs an instruction reflecting the operation performed by the user to the data reading unit 5 and the layout redefinition unit 6. For example, the operation unit 2 generates a signal representing the content of the user instruction and outputs the signal to the data reading unit 5 and the layout redefining unit 6.

(Content acquisition unit 3)
The content acquisition unit 3 acquires predetermined content displayed on the display by the information terminal device 1 through a communication network 50 such as the Internet. For example, a web page is acquired as content data by accessing a website. Furthermore, an electronic book is acquired as content by accessing a predetermined server that provides the electronic book.

  Note that the content acquisition unit actually acquires content data representing the content through the communication network 50 and stores it in the content database 4. The content database 4 stores content data representing content such as web pages, digital broadcast programs, and electronic books. The content database 4 is formed in a memory (not shown) in the information terminal device 1.

(Data reading unit 5)
The data reading unit 5 reads content data representing content from the content database 4 and outputs it to the layout redefinition unit 6. At this time, the data reading unit 5 reads content data representing content specified by the user through the operation unit 2, for example.

(Layout Redefinition Unit 6)
The layout redefinition unit 6 determines that the content is displayed when at least one of the resolution of the predetermined display on which the information terminal device 1 displays the content and the size of the predetermined display area on the display are different from a predetermined reference value. Redefine a predefined display layout to a different display layout. Here, “resolution” is an index representing how fine an object can be displayed on the display. For example, it is defined by a numerical value such as 1024 × 768 dots. On the other hand, “the size of the display area of the display” is one index representing the area of the display area. This size is, for example, the size of the window displayed on the display. Further, when the content is displayed on the full screen on the display, the display size itself corresponds to the “display area size”. For example, it is defined by a numerical value such as 40 inches diagonal or 200 mm × 100 mm.

  As will be described later, the information terminal device 1 includes a built-in display 8 and a projector screen 10 as two displays. Therefore, for example, when at least one of the resolution of the built-in display 8 and the size of the display area of the built-in display 8 is different from a predetermined reference value, the display layout is redefined. Further, when at least one of the resolution of the projector screen 10 and the size of the display area of the projector screen 10 is different from a predetermined reference value, the display layout is redefined.

  In the information terminal device 1, the resolution of the built-in display 8 is smaller than a predetermined reference value. Furthermore, the size of the display area of the built-in display 8 is also smaller than a predetermined reference value. As a result, the layout redefinition unit 6 redefines the display layout of the content displayed on the built-in display 8. Note that these predetermined reference values are stored in advance in a memory (not shown) in the information terminal device 1. Furthermore, the information terminal device 1 can appropriately change a predetermined reference value to another value in accordance with a user instruction.

  The layout redefinition unit 6 generates layout data representing the redefined display layout and associates it with input content data. Thereby, the layout redefinition unit 6 redefines the display layout when displaying the content on the display to be different from the predetermined display layout. The layout redefinition unit 6 outputs the input content data to the display unit 7 and the projection unit 9. In the present embodiment, the layout redefinition unit 6 displays content data including layout data representing the redefined display layout on the display unit 7. Further, the content data as it is, that is, content data including layout data representing the original display layout is output to the projection unit 9.

(Display unit 7 and built-in display 8)
The display unit 7 displays the content represented by the input content data on the built-in display 8. The built-in display 8 is, for example, a liquid crystal display built in the information terminal device 1. In the information terminal device 1, the resolution of the built-in display 8 is smaller than the resolution of the projector screen 10. On the other hand, the size of the display area in the built-in display 8 is often smaller than the display area in the projector screen 10. That is, the amount of information that can be displayed by the built-in display 8 is basically smaller than the amount of information that the projector screen 10 displays.

(Projector 9 and projector screen 10)
The projection unit 9 displays the content represented by the input content data on the projector screen 10. That is, this content is projected onto the projector screen 10. The projector screen 10 is a screen generated by the projection unit 9 projecting light onto a predetermined surface existing outside the information terminal device 1. In the information terminal device 1, the resolution of the projector screen 10 is larger than the resolution of the built-in display 8. On the other hand, the size of the display area on the projector screen 10 changes according to the distance between the surface on which light is projected and the information terminal device 1. Therefore, this size is basically larger than the display area of the built-in display 8, but is smaller depending on the conditions. That is, in the information terminal device 1, the amount of information that can be displayed on the projector screen 10 is basically larger than the amount of information that can be displayed on the built-in display 8, but is smaller depending on conditions.

  In the following, for convenience of explanation, the size of the display area on the projector screen 10 is always larger than the size of the display area on the built-in display 8.

(Display information acquisition unit 11 and distance measurement unit 12)
The display information acquisition unit 11 acquires information related to the built-in display 8. For example, the resolution of the built-in display 8 and the size of a predetermined display area on the built-in display 8 are acquired. The display information acquisition unit 11 outputs the acquired information to the layout redefinition unit 6. These pieces of information are used when the layout redefinition unit 6 redefines the display layout of the content displayed on the built-in display 8.

  The display information acquisition unit 11 further acquires information related to the projector screen 10. For example, the resolution and size of the projector screen 10 are acquired. The size of the projector screen 10 is determined according to the position of the information terminal device 1 and the projector screen 10. Therefore, in the information terminal device 1, the distance measuring unit 12 measures the distance between the information terminal device 1 and the projector screen 10. Based on this distance and the planar spread of light when the projection unit 9 projects, the size of the projector screen 10 is calculated. The distance measuring unit 12 outputs the calculated size to the layout redefining unit 6. The display information acquisition unit 11 outputs the information about the projector screen 10 acquired in this way to the layout redefinition unit 6.

(2 displays)
As described above, the information terminal device 1 includes two displays. That is, the built-in display 8 and the projector screen 10. This point will be described below with reference to FIG. FIG. 2 is a diagram showing that the information terminal device 1 includes a built-in display 8 and a projector screen 10.

  According to this figure, the information terminal device 1 can simultaneously display contents in conjunction with the built-in display 8 and the projector screen 10. In other words, the built-in display 8 displays a screen with a simpler display layout, and the projector screen 10 displays a screen with a more complicated display layout. The information terminal device 1 further includes an up key 21 and a down key 22 as a part of the operation unit 2. The user performs an operation of scrolling the screen displayed on the built-in display 8 in the vertical direction by using the up key 21 and the down key 22. Thereby, the display unit 7 scrolls and displays the screen displayed on the built-in display 8.

  The built-in display 8 is at least either smaller in resolution or size than the projector screen 10. That is, the information terminal device 1 includes two displays having different amounts of information that can be displayed. Here, the information terminal device 1 displays the content on the projector screen 10 based on a more complicated display layout defined in advance for the content. On the other hand, based on the redefined simpler display layout, the content is displayed on the built-in display 8. At this time, the information terminal device 1 displays at least a part of a screen constituted by a plurality of objects displayed on the projector screen 10 on the built-in display 8. That is, a screen with a simpler display layout displayed on the built-in display 8 is not displayed on the projector screen 10 as it is. Thereby, the information terminal device 1 can prevent the screen of a simpler display layout displayed on the built-in display 8 from being displayed on the projector screen 10 as it is.

(Process for displaying content on projector screen 10)
An example of the flow of processing when the information terminal device 1 displays content on the projector screen 10 will be described below with reference to FIG. FIG. 3 is a flowchart showing the flow of processing when a web page is acquired as content and the acquired web page is displayed on the projector screen 10 without redefining the display layout.

  According to this figure, in the information terminal device 1, the content acquisition unit 3 accesses a website through the communication network 50 (step S31). Thereby, the content acquisition unit 3 acquires a predetermined web page as content from the accessed website (step S32). The content acquisition unit 3 stores the acquired web page in the content database 4. This web page is read by the data reading unit 5 and output to the layout redefining unit 6.

  Next, the display information acquisition unit 11 acquires the resolution of the projector screen 10 (step S33). The layout redefinition unit 6 compares the resolution of the projector screen 10 acquired by the display information acquisition unit 11 with a predetermined reference value. The predetermined reference value is stored in advance in a memory (not shown) in the information terminal device 1.

  In the information terminal device 1 according to the present embodiment, the resolution of the projector screen 10 is larger than a predetermined reference value. Accordingly, the layout redefinition unit 6 confirms that the resolution of the projector screen 10 is larger than a predetermined reference value (step S34). That is, it is determined not to redefine the display layout of the web page. Instead, it is determined to display the web page on the projector screen 10 by using the original display layout (step S35). As a result, the layout redefinition unit 6 outputs the input web page to the projection unit 9 as it is. The projection unit 9 displays a plurality of objects included in the web page on the projector screen 10 based on a display layout previously defined for the input web page (step S36).

(Process for displaying content on the built-in display 8)
The flow of processing when the information terminal device 1 displays content on the built-in display 8 will be described below with reference to FIG. FIG. 4 shows details of processing when acquiring a web page as content, redefining the display layout of the web page to a simple display layout, and displaying the content on the built-in display 8 based on the redefined display layout. It is a flowchart which shows.

  According to this figure, in the information terminal device 1, the content acquisition unit 3 accesses the website through the communication network 50 (step S41). Thereby, the content acquisition part 3 acquires a predetermined web page as a content from the accessed website (step S42). The content acquisition unit 3 stores the acquired web page in the content database 4. This web page is read by the data reading unit 5 and output to the layout redefining unit 6.

  Next, the display information acquisition unit 11 acquires the resolution of the built-in display 8 (step S43). The layout redefinition unit 6 compares this resolution with a predetermined reference value. The predetermined reference value is stored in advance in a memory (not shown) in the information terminal device 1.

  In the information terminal device 1 according to the present embodiment, the resolution of the built-in display 8 is larger than a predetermined reference value. From this, the layout redefinition unit 6 confirms that the resolution of the built-in display 8 is smaller than a predetermined reference value (step S44).

(Summary)
As described above, the information terminal device 1 changes the display layout of content to be displayed on the projector screen 10 and the built-in display 8 regardless of whether a web page is displayed or a digital broadcast program is displayed. That is, the projector screen 10 displays a plurality of objects included in the content as a screen with a more complicated display layout based on the original display layout. Thereby, the larger display capability which the projector screen 10 has can be utilized to the maximum. On the other hand, the built-in display 8 displays a plurality of objects based on a redefined display layout, that is, a simpler display layout. Thereby, it is possible to prevent excessive information from being displayed on the built-in display 8 having a display capability smaller than that of the projector screen 10. That is, the information terminal device 1 can display a screen with an optimal display layout according to the display capability of the display that displays the content.

(Example of data structure of e-book)
The information terminal device 1 can display not only web pages and digital broadcast programs, but also electronic books on the display as contents. Therefore, a data structure of content data representing an electronic book displayed on the built-in display 8 and the projector screen 10 by the information terminal device 1 will be described below with reference to FIG. FIG. 7 is a diagram illustrating an example of a data structure of an electronic book processed by the layout redefinition unit 6.

  The content data shown in FIG. 7 further includes a “text” tag. This tag defines the display of the text object “Nineno-no-Neino-no-Niseno”. Further, “<image, width = 2 columns> image 1.jpg </ image>” is included as an image tag. This tag defines that image 1 is displayed with a width of two columns.

  According to this figure, content data representing an electronic book is composed of a plurality of tags. This content data follows a format substantially similar to the table representation in HTML. Each tag defines display layout information for displaying an object. For example, the content data shown in FIG. 7 includes a tag “<page, row = 2 rows, column = 3 columns>” in the first row. This tag defines that a plurality of objects are displayed by a table of one page and two rows and three columns.

  As described above, the content data shown in FIG. 7 includes a plurality of objects and layout data that defines the display layout of these objects. This display layout defines that a plurality of objects are displayed in a matrix as shown in FIG.

(Screen of electronic book displayed on projector screen 10)
A screen displayed on the projector screen 10 by the information terminal device 1 based on the content data to be formed shown in FIG. 7 will be described below with reference to FIG. FIG. 8 is a diagram showing a screen of the electronic book displayed on the projector screen 10 by the information terminal device 1 based on a predefined display layout.

  According to this figure, the projection unit 9 displays a plurality of objects in a matrix on the screen of the projector screen 10. At this time, two objects are displayed in the first row in this table. In other words, the text “Ainoue Kakikoshi Koshisashisei Nenuni no no” is displayed in the left column in the first row, and image 1 is displayed in the right column. The projection unit 9 further displays three objects on the next line. That is, the image 2 is displayed in the leftmost column in this row, the text “abcdefghijklmnopqrstuvwxyz012345679” is displayed in the middle column, and the text “ABCDEFGHIJKLMNOPQRSTUVWXYZ” is displayed in the rightmost column. As described above, the projection unit 9 places the electronic book on the projector screen 10 based on the original display layout defined in advance in the electronic book, that is, the display layout that is defined so as to display a plurality of objects in a more complicated manner. indicate.

(Display layout redefinition process)
When displaying the electronic book represented by the content data shown in FIG. 7 on the built-in display 8, the information terminal device 1 redefines the original display layout defined in advance to a simpler display layout. Thereby, even if the information terminal device 1 displays the same electronic book, when displaying it on the built-in display 8, it displays based on the redefined simpler display layout. Therefore, the flow of processing when the information terminal device 1 redefines the display layout by using the content data shown in FIG. 7 will be described below with reference to FIG.

  FIG. 9 is a flowchart showing the flow of data processing executed by the information terminal device 1 when redefining the display layout. According to this figure, the layout redefinition unit 6 reads out one row of tags from the content data shown in FIG. 7 (step S91). At this time, it is determined whether or not the read tag is a text tag (step S92). When the determination result in step S92 is “true” (Yes), the layout redefinition unit 6 writes this tag in the temporary memory (step S94). On the other hand, when the determination result in step S92 is “false” (No), the layout redefinition unit 6 determines whether or not the read tag is an image tag (step S93). When the determination result in step S93 is “true” (Yes), the layout redefinition unit 6 writes this tag in the temporary memory (step S94), while when the determination result in step S93 is “false” (No) ), The layout redefinition unit 6 does not write the read tag in the temporary memory.

  As described above, when the tag read from the content data is a text tag or an image tag, the layout redefinition unit 6 writes the tag in the temporary memory (step S94). On the other hand, when the read tag is neither a body tag nor an image tag, for example, a page tag, this tag is not written in the temporary memory. That is, the process of writing the tag into the temporary memory is skipped.

  After processing the read tag, the layout redefinition unit 6 determines whether or not the currently read line is the last line in the content data (step S95). When the determination result is “true” in step S95 (Yes), the layout redefinition unit 6 ends the process. On the other hand, when the determination result in step S95 is “false” (No), the layout redefinition unit 6 reads the next row and repeats the processing from step S91 to step S95.

(Content data with redefined display layout)
Through the processing shown in FIG. 9, the layout redefinition unit 6 generates content data including a text tag and an image tag in a temporary memory. The configuration of the content data will be described below with reference to FIG. FIG. 10 is a diagram illustrating an example of a data structure of content including layout data representing a redefined display layout.

  According to this figure, the layout redefinition unit 6 generates content data including four body tags and three image tags from the content data shown in FIG. This content data includes only a text tag and an image tag as tags. That is, it does not include a tag that defines the display position of the object on the screen. Instead, the display layout defined for the content represented by the content data of FIG. 10 is simpler than the display layout defined for the content represented by the content data of FIG. In this way, the layout redefinition unit 6 redefines the original display layout, that is, a more complicated display layout, to a simpler display layout by generating the content data of FIG. 10 from the content data of FIG.

(Electronic book screen displayed on the built-in display 8)
The layout redefinition unit 6 generates content data including only a text tag and an image tag and outputs the content data to the display unit 7. The display unit 7 displays an electronic book with a simpler display layout on the built-in display 8 based on the input content data.

All the underlines that have been applied to the position of "are deleted. As a result, the underline starts from “ke” on the screen of the projector screen 10. The projection unit 9 further has a position “9” corresponding to the ninth character “0” from the position “0” that was the last character before the built-in display 8 was scrolled on the projector screen 10. Until newly underlined. Thereby, the projection part 9 can change the display state of the projector screen 10 according to the screen of the internal display 8 being scrolled.

(Another example of tag)
The information terminal device 1 can also display content on the built-in display 8 and the projector screen 10 by using content data including tags including instructions related to object display. The “instruction related to object display” here is, for example, an instruction indicating that an object is not displayed on a specific display. An example of content data used by the information terminal device 1 at this time will be described below with reference to FIG.

  FIG. 20 is a diagram illustrating an example of a tag including an instruction related to display of an object. The content data shown in FIG. 20 includes a body tag and an image tag that contain instructions related to object display. The body tag includes an instruction indicating that the object is not displayed on the projector screen 10 as the text “projection screen non-display”. In the present embodiment, this projection screen means the projector screen 10. The image tag includes an instruction indicating that the object is not displayed on the built-in display 8 as the text “mobile screen non-display”. In the present embodiment, this portable screen means the built-in display 8.

  The projection unit 9 that displays the content based on the content data does not display the text “That ... Neno” on the projector screen 10. On the other hand, image 1 is displayed.

  The display unit 7 also displays content on the built-in display 8 based on the content data. At this time, the display unit 7 displays the text “Ah… Neno” on the built-in display 8. On the other hand, image 1 is not displayed.

  As described above, the information terminal device 1 can easily determine whether or not to display each object based on the instruction regarding the display of the object included in each tag. The display unit 7 may determine whether to display or hide an object according to the tag type as well as the “display” or “non-display” attribute defined in advance in the tag. . For example, when an “image” tag is defined, no image is displayed, and when an “body” tag is defined, text can be displayed.

  As described above, the information terminal device 1 redefines the display layout when the resolution of the display and the size of the display area are smaller than a predetermined reference value. At this time, the information terminal device 1 redefines the display layout so that a plurality of objects included in the content are displayed more simply. Thereby, the information terminal device 1 displays a plurality of objects with a simpler display layout than the original display layout based on the redefined display layout. Thus, the information terminal device 1 can display a screen with a simpler display layout on a display that can display more information. That is, the information terminal device 1 can prevent excessive information from being displayed on a display having a smaller information display capability.

(Redefine the display layout to a more complex display layout)
The information terminal device 1 may redefine the display layout when the resolution of the display and the size of the display area are larger than a predetermined reference value. At this time, the information terminal device 1 redefines the display layout so that a plurality of objects included in the content are displayed in a more complicated manner. Thereby, the information terminal device 1 displays a plurality of objects with a display layout that is more complex than the original display layout, based on the redefined display layout. In this way, the information terminal device 1 can display a screen with a more complicated display layout on a display that can display more information.

  The projection unit 9 displays a portion of the screen of the projector screen 10 corresponding to the screen of the built-in display 8 in a state different from the normal state. At this time, the projection unit 9 may display only the first character displayed on the built-in display 8 in a different state from the corresponding part. For example, the background color and the character color of this leading character may be inverted and displayed. The projection unit 9 may further display only the last character displayed on the built-in display 8 in a different state from the corresponding portions. At this time, the background color and the character color of the last character may be reversed and displayed.

  The information terminal device 1 has two displays having different resolutions and / or sizes. That is, the information terminal device 1 includes a built-in display 8 and a projector screen 10. By providing such two displays, the information terminal device 1 can display different information on each of the two displays.

(Example of information to be displayed)
For example, the information terminal device 1 may display an object that is determined not to be displayed on the built-in display 8. At this time, this object is not displayed on the projector screen 10.

  For example, it is preferable that this object is not seen by anyone other than yourself. The information terminal device 1 does not display this object on a display that can display more information. Thereby, for example, when the user looks at the built-in display 8 and a person other than the user is looking at the projector screen 10, the user can confirm this object, while preventing a person other than the user from seeing the object. .

  For example, the information terminal device 1 may not display text that is determined not to be displayed on the built-in display 8. On the other hand, this text is displayed on the projector screen 10.

  This text is preferably not seen by anyone other than yourself, for example. That is, the information terminal device 1 does not display this text on a display that can display more information. Thus, for example, when the user looks at the built-in display 8 and a person other than the user is looking at the projector screen 10, the user can confirm this text, while preventing anyone other than the user from seeing this text.

  For example, the information terminal device 1 may display an image included as an object in the content on the projector screen 10 and may not display the image on the built-in display 8. That is, an image is not displayed on a display with less information that can be displayed. Thereby, the information terminal device 1 can prevent excessive information from being displayed on the built-in display 8. On the other hand, the user can surely confirm this image on the projector screen 10.

  For example, the information terminal device 1 may display an explanatory text explaining an image included in the content on the built-in display 8. Thereby, for example, the user can see the explanatory text displayed on the built-in display 8. On the other hand, a person watching the projector screen 10 cannot see the text displayed on the built-in display 8. Instead, the image described by this text displayed on the projector screen 10 can be seen. Thereby, for example, the user can use the information terminal device 1 as a presentation tool.

(Example of redefining the layout unconditionally)
In the information terminal device 1, when the projection unit 9 displays content on the projector screen 10, the layout redefinition unit 6 unconditionally redefines the display layout without using information on the display size and resolution. can do. That is, the projector screen 10 is a display whose display size can be changed, but is originally a display intended to display larger than the built-in display 8. Therefore, the layout redefinition unit 6 may redefine the display layout unconditionally for a specific display such as the projector screen 10 while reflecting the purpose of use of the user.

  In addition, this invention is not limited to embodiment mentioned above, A various change is possible in the range shown to the claim. In other words, embodiments obtained by combining technical means appropriately changed within the scope of the claims are also included in the technical scope of the present invention.

  For example, the information terminal device 1 can also display content on a display other than the above-described built-in display 8 or projector screen 10 that the information terminal device 1 does not have. For example, the content can be displayed on a display that is connected to the information terminal device 1 by wired or wireless communication. Furthermore, the structure provided with two displays in which at least any one of a resolution and a display area are provided in one housing | casing may be sufficient. Further, the display provided in the information terminal device 1 is one in which the resolution is automatically switched between the first state and the second state when the arrangement state in the housing is different due to, for example, a rotation operation. May be. The display may be one that allows the user to manually switch the resolution.

  Further, the display unit 7 and the projection unit 9 may cache the input content data in a temporary memory and use it repeatedly. Or the display part 7 does not need to use the layout data showing the redefined display layout newly contained in content data. At this time, the display unit 7 and the projection unit 9 use the layout data before redefinition originally included in the content data. For example, the display unit 7 ignores an instruction for defining the display layout of the object included in the tag read from the content data. Thereby, an object having a simpler display layout is displayed without redefining the display layout.

  As described above, the layout redefinition unit 6 may redefine the display layout so that the object is displayed more simply when at least one of the resolution and the size is smaller than a predetermined reference value. For example, the display layout may be redefined to display multiple objects with fewer columns. Further, the display layout may be redefined so that a plurality of objects are displayed with fewer lines. Furthermore, the display layout may be redefined so that a plurality of objects are displayed in one column. Further, the display layout may be redefined so that a plurality of objects are displayed by one line.

  The layout redefinition unit 6 may redefine the display layout so that the content is displayed on one line on the built-in display 8. At this time, the display unit 7 can scroll the screen of the built-in display 8 in the horizontal direction. When the user presses the up key 21 or the down key 22, the display unit 7 may display the next chapter or page of the electronic book on the built-in display 8.

  The display unit 7 may display a summary of the text object when displaying the content on the built-in display 8. That is, if the text object contained in the content data is summarized and only a part thereof is displayed on the built-in display 8. Alternatively, the display unit 7 may extract only a part of the beginning of the text object and display this as a link to the entire text of the text.

Direct measurement of display size Note that the information terminal device 1 measures the size of specific information (characters and images) displayed on the projector screen 10 and identifies the size of the projector screen 10 based on the size. You can also. At this time, the display unit 7 displays the font in which the same font size is defined on the built-in display 8 and the projector screen 10. Thereby, the information terminal device 1 captures a font of a specific size displayed on the projector screen 10 with a camera (not shown), and extracts the font by image recognition. Based on this result and the distance information measured by the distance measuring unit 12, the size of the specific font is determined. The size of this font is compared with the size of the font that is displayed on the built-in display 8 and that defines the same font size. Based on the comparison result, it is determined which of the built-in display 8 and the projector screen 10 is larger in current size. Further, such a process can be performed not only for a specific font but also for a specific display target having the same display size definition.

(Information terminal device 1 with other configuration)
Further, the information terminal device 1 according to the present invention can also be realized as a configuration shown in FIG. Therefore, the information terminal device 1 having the configuration shown in FIG. 21 will be described below.

  FIG. 21 is a block diagram illustrating a configuration of the information terminal device 1 including the layout selection unit 13 and the layout database. The information terminal device 1 shown in this figure includes a layout selection unit 13 instead of the layout redefinition unit 6 described above. The layout selection unit 13 selects a display layout to be applied to the content displayed on the built-in display 8 or the projector screen 10 from the layout database 14. The layout database 14 stores in advance data representing a display layout capable of optimal display corresponding to at least one of the resolution and size of various displays on which the information terminal device 1 displays content.

  Below, the information terminal device 1 demonstrates the example which displays the plain text data which does not contain layout data on the built-in display 8 and the projector screen 10 as content data. In this example, as an improved example of the layout data shown in FIG. 7, no text is inserted between the <body> tag and the </ body> tag and the <image> tag is defined in the layout database 14. Layout data not yet stored is stored in advance. The data reading unit 5 reads the plain text data from the content database 4 and outputs it to the layout selection unit 13. The layout selection unit 13 selects from a layout database representing a display layout to be applied to this plain text data, based on information about the resolution and size of the built-in display 8 and the projector screen 10 acquired by the display information acquisition unit 11.

  The layout selection unit 13 selects data representing a simpler display layout among the data stored in the layout database 14 for the plain text displayed on the built-in display 8. For example, the simplest display layout data that displays the content as it is is selected. As a result, the selected layout data is included in the plain text data and output to the display unit 7. The display unit 7 displays the content of the display layout represented by the input layout data on the built-in display 8. That is, the plain text is displayed on the built-in display 8 as it is. Therefore, content with a simpler display layout is displayed on the built-in display 8 which is a display having a smaller resolution and size.

  On the other hand, the layout selection unit 13 selects data representing a more complicated display layout among the data stored in the layout database 14 as the content to be displayed on the projector screen 10. For example, the layout data in which the <text> tag is defined is selected. As a result, the selected layout data is included in the plain text data and output to the projection unit 9. The projection unit 9 projects the content of the display layout represented by the input layout data onto the projector screen 10. That is, a predetermined number of characters are inserted from the beginning of the plain text between the <body> tag and the </ body> tag and projected. Therefore, contents of a more complicated display layout are displayed on the projector screen 10 which is a display having a larger resolution and size.

  The information terminal device 1 may include both the layout redefinition unit 6 and the layout selection unit 13 described above. In this case, the layout selection unit 13 selects the display layout redefined by the layout redefinition unit 6 as the display layout to be applied to the content.
