  FIG. 4 shows a specific example of the functional configuration of the content display apparatus according to the present embodiment. Each function shown in FIG. 4 is a function realized by the CPU 50 reading and executing a program recorded in the RAM 60 or the flash memory 40.

  Referring to FIG. 4, the content display apparatus includes a control unit 101 mainly composed of a CPU 50, a drawing position management unit 107, a display layout creation unit 113, a drawing unit 119, an output screen designation unit 121, a touch panel 15, An operation input unit 103 including a key 30 and the like, a data input unit 105 including a reading device of the external flash memory 40, buffers 109, 111, 115, and 117 having a data structure stored in the RAM 60, 2 includes an upper screen display unit 123 configured with the two display devices 20 and the like, and a lower screen display unit 125 configured with the first display device 10 and the like.

  Furthermore, the data structure stored in the RAM 60 is shown in FIG. Referring to FIG. 5, RAM 60 stores an upper screen display position storage buffer 109, a lower screen display position storage buffer 111, a display layout storage buffer 115, and a mark information storage buffer 117 as data structures.

  The upper screen display position storage buffer 109 and the lower screen display position storage buffer 111 are buffers that store the positions of the contents displayed on the respective screens. The mark information storage buffer 117 is a buffer for storing information about marks to be described later, which is added to a display layout that is a layout for displaying content on the screen. Specifically, the mark information storage buffer 117 includes the number of added marks and individual marks. Information on the position on the upper screen indicated by the mark is stored. As the information related to the position, when the content that is the document data is displayed, the position information of the row element on the upper screen, for example, the offset value from the head of the document data file is applicable. The display layout storage buffer 115 is a buffer for storing a display layout that is a layout for displaying content on both screens, and a specific example will be described later.

  The operation input unit 103 receives an operation input from the user and outputs an operation signal to the control unit 101. The control unit 101 controls the data input unit 105, the drawing position management unit 107, the display layout creation unit 113, the drawing unit 119, and the output screen designation unit 121 based on the operation signal input from the operation input unit 103. Output signals and control them.

  The data input unit 105 reads a predetermined amount of designated content data in accordance with a control signal from the control unit 101.

  FIG. 6 shows a specific example of the structure of document data input from the data input unit 105. As a specific example, there is document data in a format that is freely laid out according to a screen size, a font to be used, and the like without a page break like an HTML (Hypertext Markup Language) document. This type of data is referred to as flow-type content here.

  The flow-type content is usually composed of a plurality of flows. A flow refers to data that is semantically organized, such as the text of chapter 1 and the text of chapter 2 in flow-type content, and generally one content includes one or more flows.

  Each flow is usually composed of a plurality of blocks. A block is a flow divided by an appropriate size in order to speed up display processing.

  Each block includes characters and tags that specify links and masks. A tag specifies a link or a mask by inserting a start tag and an end tag before and after a character as in HTML.

  Since the layout of content differs depending on the screen size of the display device and the font used, the content display device must read the data from the beginning of the content and create a display layout even when displaying from the middle of the content. In general, the flow-type content has such a structure, but the content display device can read data in units of blocks and create a display layout. Therefore, even when displaying from the middle of the content, it can be processed at high speed.

  The data input unit 105 reads a designated block in accordance with a control signal from the control unit 101. Then, the read block of content data is transferred to the control unit 101.

  The display layout creation unit 113 creates a display layout corresponding to the content data passed from the control unit 101 in block units in accordance with a control signal from the control unit 101, and stores it in the display layout storage buffer 115.

  FIG. 7 shows a specific example of the display layout stored in the display layout storage buffer 115. Referring to FIG. 7, display layout creating section 113 creates a display layout having a line size that matches the display screen width, and each line is managed by a line number. The display layout storage buffer 115 stores, for each line, information about line elements (characters) included in the line and information about the line itself.

  Specifically, the information on the line element corresponds to the position (offset value) from the beginning of the document data file, the character code indicating the character itself, the character type (normal character, link character, mask character), and the like.

  Specifically, the information regarding the line itself corresponds to the start position, end position, and line height of the line. The start position and end position of each line are represented by the minimum offset value and the maximum offset value of the line element included in the line from the beginning of the document data file.

  A method of creating a display layout in units of blocks in the display layout creating unit 113 will be described with reference to FIGS.

  First, it is assumed that the display layout is a block layout of the block number n as shown in FIG. 8 and the display as shown in FIG. 11 is displayed on the lower screen and the upper screen of the display devices 10 and 20. As shown in FIG. 11, since the layout for eight lines with line numbers 0 to 7 is displayed on the lower screen and the upper screen, the display range of the display layout shown in FIG. It becomes.

  In this state, when “page feed” for moving the page in the forward direction of the content is instructed, the control unit 101 checks whether the display layout stored in the display layout storage buffer 115 includes a layout to be displayed after page feed. Is done. In this specific example, the display range after page turning is up to the line number 8 which is the first line of the display range after page turning and the height of each line is reached to reach the height of the screen. As shown in FIG. 5, the display layout stored in the display layout storage buffer 115 is up to line number 9 and does not reach the height of the screen. Therefore, when the page layout is instructed and the display layout of the display range after page feed does not exist in the display layout storage buffer 115, as shown in FIG. A block display layout is created. The display range is line numbers 8-15.

  When page turning is further instructed, as shown in FIG. 10, the display layout creating unit 113 creates the display layout of the next block number n + 2 by the same operation, and the display range is the line numbers 16-23. Become. Here, all the display layouts (row numbers 0 to 9) of the block with the block number n are out of the display range, and are therefore deleted from the display layout storage buffer 115 in order to save the buffer capacity. In this specific example, display layouts that are outside the display range are deleted immediately, but display layouts that do not enter the display range again after a certain number of operations have been deleted. You may make it do. By doing so, the display layout of the block once out of the display range is also stored for a predetermined period, and can be displayed at high speed even when the page is returned after the page is turned.

  The display layout creation unit 113 acquires the display position, which is information specifying the position of the content data displayed on the upper screen and the content data displayed on the lower screen, from the display layout and passes it to the control unit 101. Further, the display layout creating unit 113 creates mark information to be described later based on the content data, and stores it in the mark information storage buffer 117.

  The drawing position management unit 107 stores the display position passed from the control unit 101 in the upper screen display position storage buffer 109 and / or the lower screen display position storage buffer 111 in accordance with a control signal from the control unit 101. Alternatively, the display position is acquired from the upper screen display position storage buffer 109 and / or the lower screen display position storage buffer 111 and transferred to the control unit 101.

  The drawing unit 119 acquires a predetermined display layout from the display layout storage buffer 115 based on the display position passed from the control unit 101 according to the control signal from the control unit 101, and is displayed from the specified display position. The drawing data is passed to the output screen specifying unit 121.

  The output screen designating unit 121 designates a screen to be rendered in accordance with a control signal from the control unit 101 and passes the drawing data passed from the drawing unit 119 to the upper screen display unit 123 and / or the lower screen display unit 125. The upper screen display unit 123 and the lower screen display unit 125 display content on the lower screen of the first display device 10 and the upper screen of the second display device 20 based on the drawing data passed from the output screen specification unit 121. Is executed.

  The content displayed on the content display device includes not only document data but also images and animations, and includes elements such as characters and images. The elements included in the content include elements that execute predetermined processing or change display by being selected (focused) or selected and determined. These elements are called events. Specific examples of events include a character with a link and a character with a mask. The link is an element having a function of displaying data specified in advance by being selected and determined. The mask is selected and determined, and the mask image is displayed / hidden and positioned behind. An element having a function of hiding / displaying an element.

  As described above, the first display device 10 includes the touch panel 15 and accepts a user's direct operation input using the touch pen 16 or the like, and the second display device 20 does not accept a direct operation input. Therefore, as shown in FIG. 11, when the content displayed on the second display device 20 includes a link or mask that is an event, direct operation input for the event cannot be performed using the touch pen 16 or the like. . For this reason, the content display apparatus according to the present embodiment performs the processes shown in the following first and second embodiments.

[First Embodiment]
The content display process according to the first embodiment will be described with reference to the flowchart of FIG. The processing shown in the flowchart of FIG. 12 is realized by the control unit 101 controlling each unit shown in FIG.

  Referring to FIG. 12, first, document data is input from data input unit 105 in step S101.

  Next, in step S 103, the display layout creation unit 113 creates an upper screen display layout for displaying content on the upper screen, and stores it in the display layout storage buffer 115. In step S105, the output screen designating unit 121 designates the drawing destination as the upper screen.

  In step S107, content data within a predetermined range is drawn based on the upper screen display layout stored in the display layout storage buffer 115 in the drawing unit 119, and the drawing data is output to the output screen designating unit 121. In 123, processing for displaying the drawing data on the upper screen is executed.

  Next, in step S109, the display layout creating unit 113 creates a display layout for displaying a mark in a mark display area which is a predetermined area of the display area of the lower screen, and in step S111, the output screen designating part 121 The drawing destination is specified on the lower screen.

  In step S113, the drawing unit 119 generates drawing data and outputs the drawing data to the output screen designating unit 121. The lower screen display unit 125 executes processing for displaying the drawing data in a mark display area that is a part of the lower screen. . Here, the mark refers to a symbol, an image, or a character corresponding to an event displayed on the upper screen.

  The mark display area may be displayed / hidden according to an operation input from the key 30 or the like. Alternatively, when displaying the mark on the lower screen, the size of the content display area other than the mark display area is made dynamic, and the content display area is displayed smaller / larger as necessary to display the mark display area larger / smaller, or It may be displayed / hidden. Alternatively, it may be displayed in a pop-up or the like so as to overlap the content display area as necessary.

  Thereafter, in order to display the content in the content display area other than the mark display area of the first display device 10, in step S115, the display layout creation unit 113 creates a lower screen display layout for displaying the content on the lower screen, The data is stored in the display layout storage buffer 115. Finally, in step S117, the output screen designating unit 121 designates the drawing destination as the lower screen, and the content data within a predetermined range is generated based on the lower screen display layout saved in the display layout saving buffer 115 in the drawing unit 119. Drawing is performed and the drawing data is output to the output screen designation unit 121, and the lower screen display unit 125 executes a process of displaying the drawing data on the lower screen.

  Furthermore, the process for creating the upper screen display layout in step S103 will be described with reference to the flowchart of FIG.

  Referring to FIG. 13, first, characters are read from the document data input from data input unit 105 in step S201. When the read character is an event, that is, a character with a link added (Y in step S203), or a character with a mask added (Y in step S207), step S205 or step S209. Thus, the display layout creation unit 113 adds the character to the display layout as a character having an attribute as an event. In step S211, a layout for displaying a mark corresponding to the vicinity of the character as an event on the upper screen is added to the display layout. In step S215, information about the mark added to the display layout is stored in the mark information storage buffer 117.

  If the character read in step S201 is not an event, that is, if it is neither a character with a link nor a character with a mask (N in step S203 and N in step S207), a display layout creation unit in step S213 Step 113 adds the character as a normal character to the display layout.

  If the character is not the last character in the range for creating the display layout (N in step S217), the process returns to step S201, and the processes in steps S201 to S215 described above are repeated to process all characters.

  When the display layout of the mark display area of the lower screen is created in step S109 described above, the display layout creation unit 113 acquires information on the mark added to the upper screen display layout from the mark information storage buffer 117, and displays the mark as a mark. Create a display layout to display in the area.

  The process for creating the lower screen display layout in step S115 described above includes the process for adding the layout for displaying the mark in step S211 to the display layout in the process in step S103 shown in FIG. 13, and the process in step S215. Only the processing for storing the information of the mark added to the display layout in the mark information storage buffer 117 becomes unnecessary, and the other processing is the same as the processing shown in FIG.

  Note that the processing for adding characters to the display layout in steps S205, S209, S211, and S213 described above is shown in FIG. That is, referring to FIG. 14, in step S301, if the character read in step S201 is input and the character can be added to the line currently being laid out (Y in step S303), the layout is in progress in step S307. The line element of the character is added to the line, and the information of the character (the offset value from the head of the document data file, the character code, etc.) is stored therein. If it cannot be added to the line currently being laid out (N in step S303), a new line is added in step S305, and a line element is added to it in step S307.

  The content display as shown in FIG. 15 is performed by executing the above-described content display processing in the content display device according to the present embodiment. That is, referring to FIG. 15, as shown in FIG. 11, the content displayed on the upper screen of the second display device 20 that does not accept direct operation input using the touch pen 16 etc. When the mask is included, the event is represented in the mark display area 11 that is a different area (non-overlapping area) from the content display area on the lower screen of the first display device 10 and the vicinity of the event displayed on the upper screen. The mark is displayed.

  The user can perform the same operation input as touching an event on the corresponding upper screen by touching the mark displayed in the mark display area 11 on the lower screen with the touch pen 16 or the like. That is, in the display state shown in FIG. 15, the touch pen 16 is placed on the mark “* 1” corresponding to the character string “hand” displayed on the mark display area 11 on the lower screen and added with the link displayed on the upper screen. As shown in FIG. 16, the contents of the link destination are displayed on the upper screen.

  Further, in the display state shown in FIG. 15, the mark “* 2” corresponding to the character string added with the mask displayed on the second display device 20 displayed in the mark display area 11 of the first display device 10. By touching with a touch pen 16 or the like, the character string hidden in the mask image is displayed as shown in FIG.

  Alternatively, content display as shown in FIG. 18 may be performed by executing the above-described content display processing in the content display device according to the present embodiment. In the specific example shown in FIG. 18, at least a part of the mark display area 12 on the lower screen and the content display area overlap, and the mark is displayed on the lower screen while maintaining the display position relationship of the marks on the upper screen. . Therefore, in this specific example, the information related to the mark stored in the mark information storage buffer 117 includes information related to the display position of the mark on the upper screen.

  If the content data to be displayed is document data or the like as in this specific example, and the mark is displayed on the lower screen with the display position relationship of the mark on the upper screen, the content and mark displayed on the lower screen are displayed. 18, it is preferable to shift the position of either one (or both) of the content and the mark displayed on the lower screen so that they do not overlap as shown in FIG. In the specific example shown in FIG. 18, the display position of the document data displayed on the lower screen is shifted downward by half a line, and a mark is displayed between the lines of the character string.

  Alternatively, as shown in FIG. 19, the content displayed on the upper screen may be displayed together with the mark in the mark display area 12 on the lower screen. In that case, as described above, it is preferable to shift the position of one (or both) of the content displayed on the lower screen and the content and mark displayed on the upper screen so as not to overlap. Moreover, it is preferable that the display form of the content displayed on the lower screen is different from the content displayed on the upper screen. In FIG. 19, the display position of the document data displayed on the lower screen is shifted by half a line, and the character string and mark displayed on the upper screen are displayed between the lines of the character string displayed on the lower screen. Furthermore, the color and density of the character string displayed on the upper screen are displayed lightly.

  In the present embodiment, the content display device includes two display devices. However, the number of display devices may be any number of two or more, and at least one of the display devices is touched. It is assumed that coordinate values can be input.

  In this embodiment, it is possible to input coordinate values by touching only at least one display device due to the configuration of the apparatus. However, the position and angle of the display device, the position with the user, and the like. It may be a case where it is set that the coordinate value is input by touching at least one display device for reasons such as a relationship, a user's dominant hand, and a user's habit.

  By executing such content display processing in the content display device according to the present embodiment, it is easy even for an event displayed on a display device that cannot be directly operated by the user or a display device that is difficult for the user to operate. An operation input can be performed.

[Second Embodiment]
A content display process according to the second embodiment will be described with reference to the flowchart of FIG. The processing shown in the flowchart of FIG. 20 is also realized by the control unit 101 controlling each unit shown in FIG. In the content display processing according to the second embodiment, as shown in FIG. 11, the page is moved in the forward direction of the content in a state where continuous content is displayed in that order from the upper screen to the lower screen. This is a process executed when “feed” is instructed. In the case of normal processing, the next content is displayed by scrolling two screens as shown in FIG. In the case of this example, when normal page feed is executed, the content displayed on the upper screen includes an event link or mask, and direct operation input to the event using the touch pen 16 or the like after page feed Can not do. For this reason, the content display apparatus according to the present embodiment executes the following content display processing.

  Referring to FIG. 20, first, when the operation input unit 103 receives a page turning instruction, the control unit 101 sends a normal page feed to the display layout stored in the display layout storage buffer 115 (step S401). It is checked whether the display layout of the range displayed in (2 screens ahead) has already been created and included. If the display layout to be displayed after page feeding has not yet been created (N in step S401), the display layout creating unit 113 creates it in step S403. After that, in step S405, the display layout in the range displayed after normal page turning is acquired from the display layout storage buffer 115 by the control unit 101. In the drawing position management unit 107, the display position is stored in the upper screen display position storage buffer 109 and the lower screen display position storage buffer 111 from the acquired display layout.

  Next, in step S407, based on the display position and the display layout, the upper screen display layout for displaying on the upper screen after page turning is scanned to check whether an event is included. If an event is included (Y in step S407), the display position is returned by one line to the upper screen side (in the opposite direction to scroll) in step S409, and the display position is stored in the upper screen display position storage buffer 109 and the lower screen display position. Store in the buffer 111. Then, the process returns to step S407 to check again whether an event is included in the upper screen display layout. The processes in steps S407 and S409 are repeated until there are no more events in the upper screen display layout (N in step S407). In step S411, the drawing position management unit 107 performs upper screen display position storage buffer 109 and lower screen display position storage buffer 111. The display positions of both screens stored at the time are acquired, and the drawing unit 119 draws them on both screens.

  When the above-described content display processing is executed in the content display device according to the present embodiment, when the screen is scrolled forward by two screens (a page is sent), direct operation input using the touch pen 16 or the like is performed. The scroll amount is adjusted when the event is included in the content that should be displayed on the upper screen. That is, when scrolling by two screens as shown in FIG. 11 includes an event on the upper screen as shown in FIG. 21, when page turning is instructed, as shown in FIG. 11 is scrolled in the forward direction by the scroll amount until the first event of the content displayed in the state of FIG. 11 becomes the first line of the lower screen.

  Needless to say, it is preferable that the same processing is executed when “page return” for instructing to move the page in the reverse direction of the content is instructed. In this case, in step S407 of the above process, an event is included by scanning the upper screen display layout displayed on the upper screen before returning to the page (that is, the upper screen display layout for the currently displayed upper screen). Find out if it is. If an event is included (Y in step S407), the display position is returned by one line to the lower screen side (opposite to scrolling) in step S409, and the display position is returned to the upper screen display position storage buffer 109 and It is stored in the lower screen display position saving buffer 111.

  By executing the above-described content display processing in the content display device according to the present embodiment, the content displayed on the upper screen is scrolled forward by two screens with the event included (the page is returned). ), The scroll amount is adjusted, and the scroll amount is scrolled in the reverse direction until the final event of the content currently displayed on the upper screen becomes the last line of the lower screen.

  That is, in the display processing according to the present embodiment, the content currently displayed on the screen that can be operated and input, and the content that is displayed on the screen when scrolled forward (or backward) by two screens, The display layout in between is scanned, and the event closest to the scroll direction among the events included in the display layout is page-shifted in the end row opposite to the scroll of the screen, that is, in the forward direction of the content. The scroll amount is adjusted so that the first line of the screen is displayed on the screen and the last line is displayed when the page is moved in the reverse direction. This content display process can be executed when the content display apparatus according to the present invention includes two or more display devices that are capable of at least one operation input.

  When the page movement is instructed, the scroll amount may be fixed to one screen regardless of whether there is an event of content displayed on the upper screen where direct operation input cannot be performed using the touch pen 16 or the like. . That is, when page feed is instructed in the display state shown in FIG. 11, the page movement for one screen shown in FIG. 23 is executed, and the content displayed on the lower screen before the page movement is changed to the upper screen. The new content may be displayed only on the lower screen.

  Furthermore, when displaying the beginning of the content, as shown in FIG. 24, the beginning of the content may be displayed starting from the first row of the lower screen, and the beginning of the content may not be started from the upper screen. preferable.

  By executing such content display processing in the content display device according to the present embodiment, even when page movement (or display start from the top of the content) is instructed, it is newly displayed. It is possible to easily input an operation to an event displayed on the display device that cannot be directly operated by the user or an event that is displayed on the display device that is difficult for the user to operate.

  As other specific examples for realizing the content display device according to the present invention, FIGS. 25 and 26 show specific examples of an overview when realized by a computer.

  That is, referring to FIG. 25, in the first specific example, the screen of one personal computer is displayed on a plurality of display devices, and the coordinate values are displayed with a pen on the front display device provided with the touch panel. input. The left and right display devices do not have a touch panel. By realizing the present invention in such a form, an event displayed on the entire screen can be selected even if only one costly display with a touch panel is used and the other is a normal display.

  Referring to FIG. 26, in the second specific example, there is a first display device having a large screen at a position out of reach of the user, a second display device at the user's hand, and the second display. The device has a touch panel and inputs coordinate values with a pen. By realizing the present invention in such a form, the mobile terminal can be used even for a display device that is not suitable for intuitive operation with a touch panel because it is difficult to see when approaching like a large screen display. By using it like a so-called remote controller, an event of a document displayed on a large screen display can be selected.

  Furthermore, the display method executed by the above-described content display device can be provided as a program. Such a program is stored on a computer-readable recording medium such as a flexible disk attached to the computer, a CD-ROM (Compact Disc-Read Only Memory), a ROM (Read Only Memory), a RAM (Random Access Memory), and a memory card.
