  The present invention relates to an editing method for adding electronic data representing a memo to electronic data composed of characters, character strings, images, etc., an apparatus for implementing the method, a program, and a recording medium.

  Conventionally, a document or the like has been recorded on a paper document, but in recent years it has been recorded and stored as electronic data composed of characters, character strings, images, etc., and displayed on a display device as necessary. Yes. In this case, a technique for recording new electronic data by pasting a writing or a memo (sticky note) in the margin of the displayed data is known.

  As an example of such a technique, when handwritten image data is written in a line space or a blank space, an image processing device that enables input of relatively large characters by synthesizing handwritten image data at the resolution of the document image data And an image processing method are disclosed (see Patent Document 1).

In addition, when the layout of the content is changed, the display method in which the association display between the memo and the content portion is automatically changed following the dynamic and the content and the memo are displayed with as little overlap as possible. Etc. are disclosed (see Patent Document 2).
JP-A-8-69452 (Publication date: March 12, 1996) JP 2003-308310 A (publication date: October 31, 2003)

  However, with the conventional configuration, a sufficient amount of memos cannot be recorded in the margin range of the content, and there is a problem that the usability when recording the memos is not good.

  That is, when adding a memo consisting of handwritten data or text data to the content, if the margin range of the content is limited, the amount of memos that can be recorded is limited, and a sufficient amount of memos must be recorded There is a possibility of not being able to.

  Further, in the above prior art, the apparatus does not consider that the margin range of the content is limited. Therefore, when the user records a memo, the position and size of the memo are set in order to fit the memo in the margin range. You have to record it with care. In addition, it is difficult to obtain an easy-to-use editing state in which memos are continuously recorded, requiring a change in resolution and character size, scrolling of the display position, and the like. Further, when a memo has already been recorded in the margin range, a new memo cannot be added, and the memo cannot be recorded sufficiently.

  The present invention has been made in view of the above problems, and an object thereof is to record a sufficient amount of memos, and an easy-to-use editing apparatus, editing method, program, and program for recording memos. It is to provide a recording medium.

  An editing apparatus according to the present invention is an editing apparatus for editing memo data representing a memo for content data laid out on an output medium in order to solve the above-described problem, and includes a margin of a layout range of the content data. A comparison unit that compares the area with the layout range of the memo data, and a margin area of the layout range of the content data and the layout range of the memo data on the output medium according to the comparison result of the comparison unit And a change unit that changes the relative size.

  Here, the output of content data to an output medium means display output on a display such as a monitor, print output on paper, data output to a file, and the like. Data output to a file is data output in a data format having a layout such as PDF (Portable Document Format).

  The layout is to arrange the display target element in the display range of the output medium. The display target element is an element that can be displayed on the output medium, such as a character, an image, a figure, a symbol, or a photograph. The laid out content data includes information such as the display position, size, and outer shape of the display target element in a two-dimensional or three-dimensional coordinate space. In the following, for the sake of simplicity, it is assumed that the display range and the position of the display target element are specified in the XY coordinate space. The coordinates (X, Y) are coordinates with the upper left corner of the entire layout as the origin. Instead of the word “output”, the word “display” generally means that some information is displayed in a visually recognizable state or output to an output medium. Can also be used.

  The editing device can be connected to an output device that outputs content data to an output medium. The editing device may be configured integrally with the output device, or may be configured separately from the output device.

  The output device outputs content data as a display target element to an output medium according to a layout. That is, the output device displays the display target element in the specified size and outline at the specified display position in accordance with the layout data describing the layout of the display target element. Here, the content data is one or more collections of component element data representing display target elements. The display setting for the content data can be set. For example, when the display setting such as the character size is changed, the layout of the content data as the display target element in the output medium is changed. For example, when the size of the entire layout range (window) is changed, the content data is re-laid out, the display result is changed, and the content data becomes different. As an example of the content data, data handled by an editor, a word processor, a WWW (World Wide Web) browser, or the like corresponds.

  Here, the editing device adds or deletes display target elements in accordance with instructions using, for example, a keyboard, mouse, tablet, etc., and changes the font size of characters, changes the font color, and deforms graphics. . Thus, the editing apparatus performs general editing functions in general.

  Memo data representing a memo for content data can be added using an editing device. Here, the memo data is a general term for data input by the user to the content data, such as handwritten data and text data. The memo data includes data that can be decomposed and re-laid into display target elements for each character, such as text data. That is, text data input using a keyboard or the like is data that can be disassembled and re-laid out for display. Text data can be displayed by changing the layout by changing the number of characters in one line or changing the size of characters in a word processor. If a handwritten character can be decomposed and re-laid out in character units, it may be interpreted as a type of text data.

  The memo data includes data that cannot be re-laid out, such as handwritten data. The handwritten data means data input freehand by the user using, for example, a mouse, a tablet, a pen, or the like. Here, the definition of handwritten data is a lump of data as a display unit, and the data cannot be decomposed and re-laid out for display. Data formats include a format that is a collection of strokes that have diagonal directions, and a format that is expressed as a bitmap image.

  Note that data other than handwritten data and text data can be handled as memo data as long as it can be displayed and output. For example, image data, vector data, and the like can be handled as memo data.

  In the editing apparatus, the memo data is arranged in a margin area (margin range) in the layout range of the content data. The margin range means a range in which each display target element of the content data is laid out in the content layout range on the output medium and the margin is left. The procedure for extracting margins may be to extract all margin ranges when content data is displayed, or only the margin range necessary for processing based on the position where editing started with a pen or the like. It may be extracted.

  The method of defining the margin range is not limited to this, and the remaining portion in which the display target elements are laid out may be used as the margin range for the content data and the memo data. Even if it is defined in this way, the description should be consistent. In the following, for the sake of simplicity, it means a range that is left over by laying out content data.

  The editing apparatus extracts the margin range according to the layout arrangement of the content data. Also, the editing device extracts the size, position, etc., of the memo data as the layout range of the memo data.

  The comparison unit of the editing device compares the size, position, and the like of the blank area of the content data layout range and the layout range of the memo data. For example, it is determined by comparing whether or not the layout range of the memo data is included in the margin area.

  The editing apparatus changes the relative sizes of the memo area and the blank area using the changing unit according to the comparison result of the comparing unit. In this case, for example, only the margin area may be changed, only the memo area may be changed, or both the margin area and the memo area may be changed.

  Thereby, for example, the relative size of the margin area can be expanded beyond the layout range of the memo data. Therefore, when the memo is continuously written, the layout range of the memo data stored in the margin range can be automatically expanded, and an easy-to-use editing apparatus can be provided.

  As described above, according to the present invention, it is possible to record notes continuously without worrying about the size of the notes. Since the margin range is changed, the memo can be recorded sufficiently.

  The editing apparatus according to the present invention is characterized in that, in the configuration described above, the changing unit changes the size of the blank area so that the area becomes wider.

  Since the area of the margin area is widened, the memo data can be continuously added without changing the layout of the memo data when the memo data is added. Therefore, memo data can be added without a sense of incongruity.

  The editing apparatus according to the present invention is characterized in that, in the configuration described above, the changing unit changes the size of the blank area so as to increase the area by changing the resolution of the content data.

  If it is determined that the margin range needs to be changed based on the comparison result, the margin range is changed by changing the resolution of the content data. Based on the result of comparing the margin range and the layout range of the memo data, the margin range is changed by changing the resolution of the content data while maintaining the layout of the memo data. Thus, an effect that a memo can be recorded is obtained. Since the margin range is changed, an effect that a memo can be sufficiently recorded can be obtained.

  That is, the margin range is acquired from the displayed content data. Also, the range of memo data recorded in the acquired margin range is acquired. The range of memo data may be acquired as a rectangular range of memo data, or may be acquired based on the position of a pen or the like. Compare the acquired margin range with the memo data range to determine whether the memo data range is not included in the margin range, or how much of the memo data range is included in the margin range. To do.

  In the editing apparatus described above, in the editing apparatus for editing memo data representing a memo in content data, means for acquiring a margin range from the layout of content data, means for acquiring a layout range of memo data, It can also be expressed as comprising a means for comparing a margin range with the layout range and a means for changing the margin range by changing the resolution of the content layout in accordance with the comparison result.

  In the editing apparatus according to the present invention, in the configuration described above, the change unit changes the size of the margin area so that the area becomes wider by changing the element spacing of the display target elements included in the content data. It is characterized by doing.

  If it is determined that the margin range needs to be changed based on the comparison result, the margin range is changed by changing the interval between the display target elements of the content data. Based on the result of comparing the margin range and the range of memo data, the margin range is changed by changing the interval of the display elements of the content data while maintaining the layout of the memo data. Therefore, it is possible to record the memo continuously. Since the margin range is changed, an effect that a memo can be sufficiently recorded can be obtained.

  That is, the margin range is acquired from the displayed content data. Also, the range of memo data recorded in the acquired margin range is acquired. The range of memo data may be acquired as a rectangular range of memo data, or may be acquired based on the position of a pen or the like. Compare the acquired margin range with the memo data range to determine whether the memo data range is not included in the margin range, or how much of the memo data range is included in the margin range. To do.

  In the editing apparatus described above, in the editing apparatus for editing memo data representing a memo in content data, means for acquiring a margin range from the layout of content data, means for acquiring a layout range of memo data, It can also be expressed as comprising a means for comparing the margin range with the layout range, and a means for changing the margin range by changing the interval between the display target elements of the content layout according to the comparison result. .

  In the editing apparatus according to the present invention, in the configuration described above, the changing unit increases the resolution of the content data, whereby the ratio of the blank area to the layout range of the content data is kept constant on the output medium. The size of the margin area is increased.

  Thus, when the resolution of the content data is increased, the size of the blank area can be increased.

  In the editing apparatus according to the present invention, in the configuration described above, the changing unit lowers the resolution of the content data and reduces the layout range of the content data on the output medium, thereby reducing the size of the margin area. It is characterized by widening.

  In this way, the size of the blank area can be increased when the resolution of the content data is lowered.

  In order to solve the above problems, an editing method according to the present invention edits memo data representing a memo for the content data laid out on the output medium, which is used in an output device that outputs the content data to an output medium. A comparison step of comparing a margin area of the layout range of the content data with a layout range of the memo data, and a margin of the layout range of the content data according to the comparison result in the comparison step And a change step of changing a relative size of the area and the layout range of the memo data on the output medium.

  If this editing method is performed by the editing device provided in the output device, the editing device according to the present invention is realized, and the same effect as described above can be obtained.

  In the editing method described above, in the editing method for editing memo data representing a memo in content data, a step of acquiring a margin range from the layout of content data, a step of acquiring a layout range of memo data, It can also be expressed as a configuration including a step of comparing a margin range with the layout range and a step of changing the margin range by changing the resolution of the content layout according to the comparison result.

  Further, in the above editing method, in the editing method for editing memo data representing a memo in content data, a step of acquiring a margin range from a layout of content data, a step of acquiring a layout range of memo data, It can also be expressed as a configuration that includes a step of comparing the margin range with the layout range, and a step of changing the margin range by changing the interval between the display elements of the content layout according to the comparison result.

  The program according to the present invention is a program for causing a computer functioning as an output device that outputs content data to an output medium to execute each of the steps in the editing method described above.

  If the above program is read and executed by a computer, the editing method according to the present invention can be realized.

  A recording medium according to the present invention is a computer-readable recording medium in which the above-described program is recorded.

  If the program of the recording medium is read and executed by a computer, the editing method according to the present invention can be realized.

  An editing apparatus according to the present invention includes a comparison unit that compares a blank area of a layout range of content data and a layout range of memo data, and a blank area of the layout range of the content data according to a comparison result of the comparison unit. And a changing unit that changes a relative size of the memo data layout range on the output medium.

  Thereby, for example, the relative size of the margin area can be expanded beyond the layout range of the memo data. Therefore, when the memo is continuously written, the layout range of the memo data stored in the margin range can be automatically expanded, and an easy-to-use editing apparatus can be provided.

  Further, the margin range may be changed by changing the resolution of the content data while maintaining the layout of the memo data, or the margin range may be changed by changing the interval of the display target elements of the content data. You can record notes continuously without worrying about the size of the note.

  The display device of this embodiment is configured to change the resolution of content data in order to display memo data appropriately. This display device will be described with reference to FIGS.

  As shown in FIG. 2, the display device (output device) 1 of the present embodiment includes a control unit 2, a storage unit (recording medium) 3, a display unit 4, an operation unit 5, an editing unit (editing device) 6, and an interface unit. 7 is provided. The display device 1 displays the content data 3 a stored in the storage unit 3 on the display panel (output medium) 4 b of the display unit 4.

  The display device 1 is connected to a network 8 having a printer 9, a storage device 10, and a terminal 11. The display device 1 can display content data on, for example, another terminal 11. The display device 1 can also cause the printer to output the content displayed on the display panel 4b.

  The control unit 2 of the display device 1 performs overall control of the display device 1. For example, the control unit 2 acquires data from the storage unit 3 or the storage device 10 of the network 8 and displays the data on the display panel 4 b of the display unit 4 or outputs it to the printer 9 of the network 8. For example, the control unit 2 writes and saves data such as content data and memo data in the storage unit 3 or the storage device 10 of the network 8.

  The storage unit 3 is a storage device of the display device 1. The storage unit 3 of the present embodiment is configured by a memory device such as a DRAM (Dynamic Random Access Memory) or a flash memory.

  The storage unit 3 stores content data 3a, memo data 3b, and setting data 3c. The content data 3a is data to be displayed including character data and image data. The memo data 3b is data that is written in the margin of the displayed content data 3a and displayed. The setting data 3c is data for setting a display state on the display panel 4b. The setting data 3c includes data about a range in which data can be displayed on the display panel 4b (range where layout is possible). The setting about the range that can be laid out is not limited to the configuration stored in the storage unit 3 but may be stored in another storage medium or input from the operation unit 5 according to a user instruction. It may be a configuration. For example, when the size of the window displayed on the display panel 4b of the display unit 4 is within a layoutable range, the control unit 2 accesses the storage unit 3 and references a window size data API (Application Data in a range that can be laid out may be acquired by calling (Program Interface). Or, for example, when printing, the control unit 2 accesses the print setting data (not shown) of the printer 9 or the storage unit 3 in which the paper settings are recorded, and calls the paper size acquisition API. May be obtained.

  The range in which the display / output medium can be laid out is a range in which display target elements including the content data and memo data can be laid out and displayed. In other words, the range that can be laid out is, for example, a portion excluding the portion that cannot be displayed on the display / output medium, the portion that cannot be used for layout / display of content data or memo data because it is used for display of window frames and the like, In addition, it corresponds to a range excluding an end portion that can be laid out but is not laid out intentionally for the sake of easy viewing (in general, “margin”, not the meaning described above).

  The display unit 4 includes a display control unit 4a and a display panel 4b. The display control unit 4a has a VRAM (Video Random Access Memory) on a graphic card (not shown). The display control unit 4a temporarily stores input data in the VRAM. The display control unit 4a converts data input to the VRAM into a display signal and outputs the display signal to the display panel 4b. The display panel 4b displays the display signal as an image. In addition, although the display panel 4b of this embodiment is a liquid crystal display panel, it is not restricted to this. For example, a plasma display, an organic or inorganic EL panel, a CRT, or the like may be used. Further, the display target of data in the display device 1 is not limited to the display unit 4, and the case of printing on a sheet by the printer 9 of the network 8 is included in the data display.

  The operation unit 5 is a user interface of the display device 1. The operation unit 5 includes a keyboard 5a, a tablet (input panel) 5b, an input pen 5c, and a mouse 5d. The user of the display device 1 can use the operation unit 5 to select the content data 3a to be displayed, enter the memo data 3b, set the setting data 5c, and the like. The configuration of the operation unit 5 is not limited to this. For example, the operation unit 5 can be configured by various means such as a voice input by a button or a microphone.

  When the user operates the keyboard 5a, the tablet 5b, the input pen 5c, the mouse 5d, or the like, the control unit 2 converts, for example, the input movement of the mouse 5d or the input pen 5c into a stroke data format. Further, for example, the control unit 2 can further recognize stroke data and convert it into text data. Further, for example, the control unit 2 can also convert characters obtained from the keyboard 5a into text data mixed with Kana / Kanji characters. Alternatively, for example, the control unit 2 can recognize voice input from a microphone (not shown) and convert it into text data. For example, the control unit 2 stores data corresponding to the operation in the storage unit 10 or the storage device 10 of the network 8, or edits the data in the editing unit 6 as necessary and causes the display unit 4 to display the data.

  The editing unit 6 is an editing device that performs general editing functions in general. The editing unit 6 adds and deletes content data and memo data as display target elements in accordance with an instruction from the user using the operation unit 5. For example, when the memo data is input from the operation unit 5, the editing unit 6 appropriately edits the memo data 3b and the content data 3a and causes the display panel 4b to display them. The editing unit 6 also changes the font size of the character, changes the font color, and deforms the figure as the layout of the content data and the layout of the memo data. The editing unit 6 arranges the memo data in the blank area of the layout range of the content data. Details of the editing unit 6 will be described later.

  The interface unit 7 is an interface with the outside of the display device 1 and functions as an input / output unit that transmits and receives data. The interface unit 7 of this embodiment is configured by a network card or the like. The interface unit 7 is connected to the network 8. The connection with the network 8 may be wired or wireless. The printer 9 of the network 8 prints print data input from the display device 1 on a sheet (output medium) (not shown). The storage device 10 of the network 8 is storage means such as an HDD (Hard Disk Drive) or a PC (Personal Computer) card that can be attached to and detached from the terminal 11.

  In addition, you may perform data transmission / reception of each part of the display apparatus 1 using the bus | bath connected to CPU which is not illustrated, for example. Alternatively, the configuration is not limited thereto, and a configuration via a communication cable or a wireless communication device may be used as long as data can be exchanged.

  The control unit 2 of the display device 1 according to the present embodiment is realized by a program (not shown) stored in the storage unit 3 being read and executed by a CPU (Central Processing Unit) (not shown). . The editing unit 6 of the display device 1 is also realized by reading and executing a program stored in the storage unit 3 by the CPU. The implementation means is not limited to a configuration using a program and a CPU, but may be a DSP (Digital Signal Processor) or a configuration using a logic circuit or the like in which a processing procedure is incorporated as a circuit. But you can. The program may be stored in the external storage device 10 instead of the storage unit 3.

  As shown in FIG. 3, the display device 1 is configured to input memo data using the input pen 5c of the operation unit 5 to the display panel 4b. Thus, since the display device 1 of the present embodiment is configured such that the display panel 4b also serves as the tablet 5b, the user can input handwritten data by using the input pen 5c on the display panel 4b. The display device 1 can be operated.

  The area on the display panel 4b is a display area where the content data 3a and the memo data 3b can be displayed. In this area, the content data 3a and the memo data 3b are displayed based on the set layout.

  Here, the editing unit 6 that edits data and changes the display state will be described in detail with reference to FIG.

  The editing unit 6 includes an editing control unit 12, a content unit 13, a memo unit 14, a margin extraction unit 15, a memo region extraction unit 16, a comparison unit 17, and a layout unit (change unit) 18.

  The editing control unit 12 controls the editing function of the editing unit 6 as a whole. The edit control unit 12 acquires the content data 3 a stored in the storage unit 3 via the control unit 2 and holds it in the content unit 13. Further, the edit control unit 12 acquires the memo data 3 b stored in the storage unit 3 via the control unit 2 and holds it in the memo unit 14. Alternatively, the edit control unit 12 receives data input by the user from the operation unit 5 and reflects the data in the memo unit 14 or the content unit 13. The configuration of the editing control unit 12 is not limited to this, and the editing control unit 12 may access the storage device 10 of the network 8 and acquire data, for example. The content data acquisition method is not limited to this, and may be another generally known acquisition method. In the following, it is assumed that the content data is prepared in advance and stored in the storage unit 3 or the storage device 10.

  The content section 13 is a storage area that is temporarily held for editing the content data 3a. The memo section 14 is a storage area that temporarily holds the memo data 3b for editing.

  Here, an example of the data format stored as the content data 3a / memo data 3b will be briefly described with reference to FIGS.

  An example of the content data 3a is stored separately for each content element to be displayed, such as elements 401 to 403 shown in FIG. Each element includes, for example, items of type, position X, position Y, width W, height H, and contents. The type represents the type of display target element such as a character string (TEXT) or an image (IMAGE). The position X and the position Y represent the X coordinate and the Y coordinate of the position of the display target element, respectively. The width W and the height H represent the size (width and height) of the area of the display target element, respectively. The content items are stored in different formats depending on the type of display target element. For example, when the type is a character string (TEXT), the content item includes font information such as a character code of the character string and a character color. When the type is IMAGE, the content item includes pixel data (Image Data) of the image.

  Note that the data structure of the content data is not limited to the data structure shown in FIG. 5, but is a generally known data structure and the like, and any other data can be used as long as it can be displayed. It may be a structure. In the following, in order to facilitate understanding, the content data 3a will be described with the type being text data.

  An example of the memo data 3b is stored separately for each element of the memo data to be displayed, such as elements 501 to 503 shown in FIG. Each element includes, for example, items of type, position X, position Y, width W, height H, contents, and change information. The type represents the type of display target element such as a character string (TEXT), handwriting (FREEHAND), or image (IMAGE). The position X and the position Y represent the X coordinate and the Y coordinate of the position of the display target element, respectively. The width W and the height H represent the size (width and height) of the area of the display target element, respectively. The content items are stored in different formats depending on the type of display target element. For example, when the type is a character string (TEXT), it includes font information such as a character code of the character string and a character color. In the case of handwriting (FREEHAND), it includes stroke data (Stroke Data). In the case of an image (IMAGE), it includes pixel data (Image Data) of the image. The item of change information represents information that has been changed by a margin range change process to be described later.

  Here, FIG. 7 shows an example of the memo data 3b when the resolution of the content data is changed by the margin range changing process. Elements 601 to 603 include, as change information, a pointer to an item “REZ (resolution)” indicating the resolution of content data to be changed when each element is displayed for each of the elements 501 to 503 shown in FIG. Yes. In this way, the pointer is stored in the change information item of each element. If it is this format, even if it is a case where a different format is used as change information, it is easily realizable. By maintaining the resolution of the content data in this way, the relationship between the size of the memo data and the size of the margin range (margin region) that includes the memo data is maintained. The position X, position Y, width W, and height H of the item may be information before changing the resolution of the content data, or may be information after that.

  Note that the data structure of the memo data is not limited to the data structure shown in FIG. 6 and FIG. 7, and is a generally known data structure that can be displayed. Other data structures may be used. In the following, for ease of understanding, a description will be given of the memo data 3b whose type is handwritten (FREEHAND).

  Here, returning to the description of the editing unit 6 shown in FIG. 4, the margin extraction unit 15 extracts the layout range of the content data from the content data held in the content unit 13. Here, the margin extraction unit 15 compares the layout possible range with the position and size of each content as to whether or not the content data can be displayed in the layout possible range. The margin extraction unit 15 outputs the layout range of the content data to the layout unit 18.

  In addition, the margin extraction unit 15 extracts the position and size of the margin area by using the content data held in the content unit 13 and the setting data 3c input from the editing control unit 12, and the comparison unit 17 Output to. More specifically, the margin extraction unit 15 calculates a content layout range in the case where content data is displayed in a layout possible range included in the setting data 3c. The margin extraction unit 15 extracts the size of the margin from the layout possible range and the content layout range. The area (content layout area) where the content is displayed on the display panel 4b is the same range as the layout possible range or the range excluding the blank range (margin region) from the layout possible range.

  The memo area extracting unit 16 extracts the layout range of the memo data from the memo data held in the memo unit 14 and outputs it to the layout unit 18. The memo region extraction unit 16 extracts the position and size of the region occupied by the memo data from the memo data held in the memo unit 14 and outputs the extracted data to the comparison unit 17.

  The comparison unit 17 compares the position and size of the margin input from the margin extraction unit 15 with the position and size of the region occupied by the memo data input from the memo region extraction unit 16. Specifically, by comparing the position and size, it is determined whether or not the area occupied by the memo data is included in the blank range of the content when the memo data is arranged in the blank range. The comparison unit 17 outputs the comparison result obtained by the determination to the layout unit 18.

  The layout unit 18 lays out the content data and the memo data according to the data from the margin extraction unit 15 and the memo region extraction unit 16. That is, the layout unit 18 performs layout changes such as changing the font size of characters, changing the font color, and deforming graphics in addition to adding and deleting display target elements, for example.

  The layout unit 18 changes the layout of the content data and the memo data according to the comparison result in the comparison unit 17. The layout unit 18 causes the content unit 13 and the memo unit 14 to temporarily hold the content data and memo data whose layout has been changed. More specifically, for example, the layout unit 18 receives the comparison result of the comparison unit 17 and changes the layout of the content data when the memo data cannot be displayed in the margin range of the content data.

  When the layout unit 18 determines that the layout needs to be changed, the layout unit 18 acquires content data / memo data from the content unit 13 / memo unit 14 via the editing control unit 12. The layout unit 18 acquires setting data 3 c in the storage unit 3 via the editing control unit 12.

  Here, the control unit 2 accesses the content unit 13 and the memo unit 14 to acquire data and outputs the data to the display control unit 4 a of the display unit 4. As a result, the data edited by the editing unit 6 is displayed on the display panel 4 b of the display unit 4.

  When the power of the display device 1 is stopped or when there is an instruction from the user, the editing control unit 12 stores the content data and memo data temporarily held in the content unit 13 and the memo unit 14 in the storage unit. 3 is stored as content data 3a and memo data 3b.

  As an example of the operation of the display device 1 configured as described above, a series of operations for recording a memo in a certain text will be described.

  First, an example of content data displayed on the display panel 4b is shown in FIG. An example text is laid out and displayed in the content layout range 801. This text is horizontally written content data composed of elements to be displayed as full-width kana characters, and has the content “limited to margins”. In the state shown in this figure, memo data is not added.

  FIG. 9 shows an example of a case where a margin range as a margin is extracted from the state shown in FIG. FIG. 9 is a diagram showing a margin range around FIG. A range 901 surrounded by a thick line is a content layout range, and a hatched range 902 surrounded by a thick line and a broken line is a blank range between the content layout range and the display target element of the content data. This margin range is in contact with any of the four sides on the top, bottom, left and right of the content layout range.

  FIG. 10, which is another example of the margin range, shows a case where all the margin ranges of the content layout range are acquired. A range 1601 surrounded by a thick line is a content layout range, and a hatched range 1602 surrounded by a thick line and a broken line is selected for all the remaining ranges with respect to the content layout range in which each display target element of content data is laid out. The margin range. In this case, for example, when the user moves the arrow 1603 for editing using the input pen 5c of the operation unit 5 and selects one point of the margin, the margin range 1602 is acquired.

  FIG. 11 showing still another example of the margin range shows a case where a rectangular margin range is acquired for the horizontally written content data shown in FIG. A range 1001 surrounded by a thick line is a content layout range, and a hatched range 1002, range 1003, and range 1004 surrounded by a broken line indicate a margin range recognized as a rectangular range. This margin range exists, for example, at the start of a paragraph or the end of a sentence.

  Here, as shown in FIG. 12, for example, when the user moves the arrow 1703 for editing using the input pen 5c of the operation unit 5 and selects a margin, the hatched lines surrounded by the broken lines in the content layout range 1701 A margin range 1702 is acquired. As a result, it is possible to acquire a partial margin range to which memo data is to be added.

  In addition, although the example of the margin range mentioned above becomes an example of a margin range each independently, it is not restricted to this, You may use the combination of several margin ranges. Further, the margin range may not be a combination of the rectangular ranges as described above. For example, it may be a range represented by a circle or an arbitrary polygonal range. Further, the margin range can be acquired at an appropriate time. For example, when all the remaining margin ranges for the content layout range are acquired, the margin range may be acquired prior to editing the memo data. Alternatively, when the memo data is edited with the mouse 5d, the input pen 5c, or the like of the operation unit 5, a part of the margin range to which memo data is to be added may be acquired. In the editing unit 6 of the display device 1, the margin extraction unit 15 shown in FIG. 4 extracts margins at a predetermined timing and a predetermined method based on the setting data 3 c in which any of the above-described methods is set. I do.

  Next, a case where memo data is added to the margin range extracted as described above will be described. Here, a case will be described in which handwritten memo data is added to the portion corresponding to the margin 1702 selected in FIG. 12 using the input pen 5c on the display panel 4b. As the contents of the handwritten memo, the handwritten memo “→ handwritten” is described in the margin after the third line “... In this case, as shown in the display panel 4b of FIG. 3, a range surrounded by a broken line is a blank range, and handwritten memo data “→ handwritten” is displayed in the blank range. Note that the broken line range shown in FIG. 3 is for explanation and is not actually displayed.

  Moreover, the handwritten memo data described here can also be handled as, for example, each memo data by the controller 2 of the display device 1 recognizing handwritten characters and converting it into text data. However, in order to make the explanation easy to understand, a rectangular range including each memo data is defined as one memo layout range. Similarly, in the following, memo data that can originally handle each character as one memo data is composed of a plurality of characters. Are handled as one memo layout range by a rectangular range including

  Here, as shown in FIG. 13, a range 1801 surrounded by a thin line arranged inside a margin range 1802 surrounded by a broken line (corresponding to the margin range 1702 in FIG. 12) is memo data “→ handwritten”. A memo layout range of a rectangular range including. FIG. 13 is an enlarged view of a part from the second line to the fourth line in FIG.

  Further, when handwritten data is further added to the state shown in FIG. 13, if the layout is not changed as it is, a blank area 1902 surrounded by a broken line (corresponding to the blank area 1802 in FIG. 13), as shown in FIG. ), The rectangular memo layout range including the memo data “→ handwritten, te” becomes a range 1901 surrounded by a thin line.

  In this case, by adding the memo data, a hatched range 1903 in the memo layout range 1901 protrudes from the margin range 1902 as shown in FIG. Therefore, the editing unit 6 of the display device 1 compares the layout range of the memo data whose size has been changed with the addition of the memo data with the corresponding margin range, and changes the layout as necessary.

  In the present embodiment, the editing unit 6 changes the layout of the content data without changing the layout of the memo data. More specifically, the editing unit 6 increases the size of the margin range by increasing the resolution of the content data. Further, when the resolution of the content data is increased, the editing unit 6 keeps the ratio of the blank area to the layout range of the content data constant.

  Here, whether to change the margin range is determined by comparing the inclusion relationship between the memo layout range and the margin range. For example, in the editing process for adding memo data, the margin range is not changed when the margin range includes the memo layout range, and the margin range is changed when the margin range cannot include the memo layout range.

  More specifically, first, as shown in FIGS. 13 and 14, the coordinates of the vertices of the rectangular ranges representing the corresponding memo layout ranges 1801 and 1901 are (Xm1, Ym1) and (Xm2, Ym2). However, (Xm1 <Xm2, Ym1 <Ym2). Further, the coordinates of the vertices of the rectangular range representing the corresponding margin ranges 1802 and 1902 are (Xs1, Ys2) and (Xs2, Ys2). However, (Xs1 <Xs2, Ys1 <Ys2). The coordinates of each vertex can be extracted from the content data 3a and memo data 3b as shown in FIGS.

  Here, when the margin range includes the memo layout range, the following formulas (1) and (2) are satisfied.

Xs1 <Xm1 <Xm2 <Xs2 Formula (1)
Ys1 <Ym1 <Ym2 <Ys2 (2)
In the state shown in FIG. 13, the above expressions (1) and (2) are satisfied, and the margin range 1802 includes the memo layout range 1801. Therefore, the comparison unit 17 of the editing unit 6 determines that it is not necessary to change the margin range.

  On the other hand, in the state shown in FIG. 14, since Xs1 <Xm1 <Xs2 <Xm2, the condition of formula (1) is not satisfied. That is, in the memo layout range 1901, the range 1903 indicated by diagonal lines is not included in the margin range 1902, so the comparison unit 17 of the editing unit 6 determines that the margin range needs to be changed.

  Although the rectangular range including each piece of memo data is described as one memo layout range here, the present invention is not limited to this. As a memo layout range, a predetermined range may be specified instead of a specified range. For example, in the editing process for adding memo data, it is determined whether or not the current position (current point) of the memo data specified by the mouse 5d, the input pen 5c, etc. of the operation unit 5 is included in the margin range. It may be determined. The coordinates of the current position of the memo data are (Xc1, Xc2), and the coordinates of the vertices of the rectangular range representing the margin range are (Xs1, Ys1), (Xs2, Ys2). However, (Xs1 <Xs2, Ys1 <Ys2). In this case, it can be determined whether or not the current position of the memo data is included in the blank range depending on whether or not the conditions of the following equations (3) and (4) are satisfied.

Xs1 <Xc1 <Xs2 Formula (3)
Ys1 <Yc1 <Ys2 Formula (4)
When Expressions (3) and (4) are not satisfied, the current position of the memo data is not included in the margin range. Therefore, the comparison unit 17 of the editing unit 6 determines that the margin range needs to be changed.

  Further, the comparison unit 17 of the editing unit 6 may determine whether or not to change the margin range based on the ratio between the included margin range and the memo layout range. For example, in the editing process for adding memo data, if the area of the memo layout range occupies an arbitrary ratio α (α is an arbitrary positive real number) with respect to the area of the margin range, there is no margin in the margin range. It is determined that the margin range needs to be changed. On the contrary, in the editing process for deleting the memo data, if the area of the memo layout range occupies an arbitrary ratio α with respect to the area of the margin range, it is assumed that there is an unnecessary range in the margin range, Judge that change is necessary. For example, assume that the coordinates of the vertices of the rectangular range representing the memo layout range are (Xm1, Ym1) and (Xm2, Ym2). However, (Xm1 <Xm2, Ym1 <Ym2). Further, the coordinates of the vertices of the rectangular range representing the margin range are (Xs1, Ys2) and (Xs2, Ys2). However, (Xs1 <Xs2, Ys1 <Ys2). The area of the margin range can be obtained by (Xs2-Xs1) × (Ys2-Ys1). The area of the memo layout range can be obtained by (Xm2-Xm1) × (Ym2-Ym1). When an arbitrary ratio set in advance is α, it is determined whether the margin range needs to be changed according to whether or not the following expression (5) is satisfied.

((Xm2-Xm1) × (Ym2-Ym1)) / ((Xs2-Xs1) ×
(Ys2-Ys1))> α (5)
The method for comparing and determining the memo layout range and the margin range is not limited to the method described above, and a generally known method for comparing other ranges may be used. .

  Since the editing unit 6 makes the determination as described above, when a memo is added to the state shown in FIG. 13, the layout is not actually in the state shown in FIG. 14 but in the following state. Be changed.

  Here, the state of FIG. 13 for the entire display area as shown in FIG. 12 is shown in FIG. A range 2001 surrounded by a thick line is a content layout range, and a range surrounded by a broken line is a margin range 2002. This margin range 2002 corresponds to the margin range 1702 shown in FIG. Since the memo layout range of the memo data “→ handwritten” is included in the margin range, the comparison unit 17 of the editing unit 6 determines that it is not necessary to change the margin range. The layout unit 18 of the editing unit 6 does not change the layout of the content data and displays it with the memo data added.

  FIG. 16 shows a state in which memo data is further added to the state shown in FIG. 15 without changing the margin range. A range 2101 surrounded by a bold line is a content layout range, and a range 2102 surrounded by a broken line is a margin range. Since the margin range 2102 is limited, when the memo data “→ handwritten, te” is added, no more memo data “chist” can be added. For this reason, in order to add all the memo data “→ handwritten, text”, it is necessary to change the margin range.

  Therefore, as shown in FIG. 17, the layout unit 18 of the editing unit 6 changes the margin range by changing the resolution of the content data. In FIG. 17, the margin range is changed by changing the resolution based on the state shown in FIG. A range 2201 surrounded by a thin line is a memo layout range, and a range 2202 surrounded by a broken line is a margin range. In the example shown in FIG. 17, the margin range is changed by changing the resolution of the content data, so that the memo data can be laid out within the margin range. Hereinafter, calculation of resolution performed by the layout unit 18 of the editing unit 6 will be described.

  First, in FIG. 14, the margin range 1902 can be expressed by coordinates (Xs1, Ys1) and (Xs2, Ys2) of two vertices. Further, the range 1903 of the protruding portion can be expressed by the coordinates (Xs2, Ym1) and (Xm2, Ym2) of the two vertices. However, (Xs1 <Xm1 <Xs2 <Xm2, Ys1 <Ym1 <Ym2 <Ys2). When the layout is changed based on this state, as shown in FIG. 17, the changed margin range 2202 can be specified by the coordinates (Xs3, Ys3) and (Xs4, Ys4) of the two vertices. However, (Xs3 <Xs4, Ys3 <Ys4).

  Here, the new resolution for changing the margin range is calculated so that the range including the margin range 1902 and the protruding range 1903 shown in FIG. 14 is the changed margin range. Alternatively, the changed margin range is calculated so as to include the margin range 1902 and the protruding range 1903 shown in FIG.

First, a rectangular range including a margin range 1902 and a protruding range 1903 can be specified by coordinates (Xs1, Ys1) and (Xm2, Ys2) of two vertices. Hereinafter, this region is referred to as an inclusion range 1904. In this case, the inclusion range 1904 is a range obtained by changing the margin range 1902 in the X direction. In order for this inclusion range 1904 to be included in the margin range 2202 after the change, the X direction of the inclusion range 1904 and the X direction of the margin range 2202 after the change need only match. That is, (Xs4-Xs3) = (Xm2-Xs1) may be satisfied. Further, the resolution may be changed at a ratio β (β is an arbitrary positive real number) so that the X direction of the blank range 1902 matches the X direction of the blank range 2202 after the change. That is, (Xs4-Xs3) = (Xs2-Xs1) × β holds. From the two equations,
Ratio β = (Xm2−Xs1) / (Xs2−Xs1) Formula (6)
It becomes. If the resolution of the content layout range in FIG. 14 is R, the changed resolution of FIG. 17 may be R × β. The resolution obtained in this way is stored as, for example, “REZ (resolution)” item of the memo data 3b shown in FIG.

  With the resolution changing process as described above, when editing the memo data in horizontal writing, the resolution of the content data can be increased and the size of the margin can be substantially changed for display.

  An example of the display operation in the display device 1 described above will be outlined based on FIG.

  The display device 1 detects, for example, a power-on instruction from the user using the operation unit 5, and the control unit 2 turns on the power of the display device 1. Thereafter, in S1, the control unit 2 acquires the content data 3a stored in the storage unit 3 and outputs the content data 3a to the editing unit 6 in S1.

  In S2, the editing unit 6 extracts (creates) content layout data from the content data 3a. In response to this, the display control unit 4a of the display unit 4 displays the contents of the content data 3a on the display panel 4b.

  In S3, the control unit 2 determines whether or not the memo data 3b in the storage unit 3 exists. The control unit 2 proceeds to S4 when the memo data 3b is stored in the storage unit 3, and proceeds to S6 when the memo data 3b is not stored in the storage unit 3. Note that the control unit 2 may determine the presence or absence of the memo data 3b in accordance with an instruction from the user detected by the operation unit 5, instead of accessing the storage unit 3.

  In S <b> 4, the control unit 2 acquires the memo data 3 b in the storage unit 3 and outputs it to the editing unit 6.

  In S5, the editing unit 6 extracts (creates) memo layout data from the memo data 3b. In response to this, the display control unit 4a of the display unit 4 displays the contents of the memo data 3b on the display panel 4b.

  In S6, the control unit 2 displays a selection on whether to change the display state on the display panel 4b. If a change instruction by the user is detected by the operation unit 5, the process proceeds to S7, and if an instruction not to change is detected, the process proceeds to S8.

  Note that the operation / instruction from the user regarding whether or not to change the display is, for example, enlargement / reduction of display, scrolling, or displaying only content data, displaying only memo data, displaying both content data and memo data・ The contents are hidden. The content of the operation may be an operation of designating two vertices of the rectangular area to be enlarged using, for example, the mouse 5d or the input pen 5c of the operation unit 5, or displayed / hidden by pressing a button, for example. It may be an operation for switching between.

  In S7, the control unit 2 changes the content of the setting data 3c in the storage unit 3 and outputs the changed content of the setting data 3c to the editing unit 6 in accordance with a change instruction from the user. The editing unit 6 changes the layout according to the contents of the setting data 3c. The data whose layout has been changed is displayed on the display panel 4 b of the display unit 4.

  In S8, the control unit 2 causes the display panel 4b to display a selection as to whether or not to edit the memo data. If the operation unit 5 detects an edit instruction, the process proceeds to S9. If an instruction not to edit is detected, the process proceeds to S10.

  The operation / instruction from the user regarding whether or not to edit is, for example, contents such as adding or deleting characters, images, etc. as memo data. For example, the user uses the mouse 5d or the input pen 5c of the operation unit 5 to add handwritten characters to the content data.

  In S9, the editing unit 6 edits the memo data in accordance with the editing operation / instruction from the user in S8. The memo data whose contents are changed is displayed on the display panel 4b in a new layout together with the content data.

  In S10, the control unit 2 causes the display panel 4b to display a selection as to whether or not to end the display change / editing process. If the operation unit 5 detects an instruction to end the process, the process ends. If an instruction not to end the process is detected, the process proceeds to S6.

  With the above editing process, the margin range of the content data can be changed when adding memo data. By extending the margin range of the content data, the range where the memo can be written is expanded, and the memo can be recorded sufficiently.

  Here, a detailed example of the content data display process shown in S2 of FIG. 18 will be described based on FIG. The content data display process is a process of creating layout data related to the content layout and displaying the contents of the content data on the display panel 4b according to the layout data.

  First, in S2-1, the editing control unit 12 of the editing unit 6 acquires the contents of the setting data 3c in the storage unit 3 and extracts the layout possible range of the display panel 4b. Alternatively, the configuration is not limited to the configuration extracted by the editing control unit 12, the layout possible range is specified by the display / output destination device, the document display program is specified, or the keyboard 5 a and the input pen 5 c of the operation unit 5. It may be configured to be designated by a user operation / instruction via the mouse 5d or the like.

  In S2-2, the margin extraction unit 15 of the editing unit 6 acquires a content layout range in which the content data is laid out from the content data 3a and the setting data 3c. The content layout range is acquired based on the layout possible range acquired in S2-1. That is, the content layout range is acquired as the same range as the layout possible range, or a range narrower than the layout possible range by removing the margins above, below, left, and right. Here, in order to simplify the description, it is assumed that the content layout range matches the layout possible range.

  In S2-3, the layout unit 18 of the editing unit 6 acquires the layout of the content data. Note that the comparison unit 17 of the editing unit 6 determines whether the position and range of each content included in the content data acquired in S1 of FIG. 18 are included in the content layout range acquired in S2-2 of FIG. Compare and determine. Then, the position and range of each content are output to the layout unit 18. The layout unit 18 arranges the content data included in the layout range from the information on the position and size included in the content data, and sets the content data as content layout data.

  In S2-4, the display control unit 4a of the display unit 4 displays the content layout data acquired by the layout unit 18 in S2-3 on the display panel 4b. When all the content data is displayed, the process ends, and the process returns to S3 in FIG.

  Content data can be displayed by the processing described above.

  Next, a detailed example of the memo data display process shown in S5 of FIG. 18 will be described based on FIG.

  In S5-1, in the editing unit 6, the margin extraction unit 15 extracts a margin range after the content is laid out. The margin extraction unit 15 extracts margins by the method set in the setting data 3c.

  In S5-2, the memo area extraction unit 16 of the editing unit 6 extracts the layout range of the memo data.

  In S5-3, the layout unit 18 of the editing unit 6 generates a layout of memo data. The layout of the memo data is obtained by arranging the memo data in the layout range based on the position and size information included in the memo data. More specifically, the margin range acquired in S5-1 and the memo layout range acquired in S5-2 are compared by the comparison unit 17, and it is determined whether or not the memo layout range falls within the margin range. If it falls within the margin range, the layout unit 18 generates memo layout data based on the memo layout range acquired in S5-2. On the other hand, if it does not fall within the margin range, in S5-3, the layout unit 18 changes the layout of the content data, for example, so that the memo layout range fits within the margin range. Data may be generated. However, it is not always necessary to change the layout in S5-3, and it may be displayed as it is.

  Note that the memo layout range is acquired as the same range as the margin range or as a range narrower than the margin range by removing margins above, below, left, and right. Here, in order to simplify the description, it is assumed that the memo layout range matches the margin range.

  In S5-4, the memo layout data generated by the layout unit 18 in S5-3 is displayed on the display panel 4b by the display control unit 4a of the display unit 4. When the display of all the memo data is completed, the process is terminated and the process returns to S6 of FIG.

  By the process described above, the memo data can be displayed when the memo data already exists.

  Next, details of an example of the display change process shown in S7 of FIG. 18 will be described based on FIG.

  In S <b> 7-1, the control unit 2 detects a selection as to whether or not to display new content data using the operation unit 5. For example, an operation such as page movement is detected by the operation unit 5. Alternatively, the selection of new separate content data is detected. If an instruction to display on the operation unit 5 is detected, the process proceeds to S7-2. If the operation unit 5 detects an instruction to hide and not display content data, for example, the process proceeds to S7-4. Alternatively, for example, when an instruction to display for a predetermined time is not detected, the process may proceed to S7-4.

  In S7-2, the layout unit 18 determines whether there is a change in the layout of the displayed content data. If there is a change in the layout, the process proceeds to S7-3 to perform redrawing. On the other hand, if there is no change in the layout of the content data, the current layout may be displayed as it is, so the process of S7-3 is omitted and the process proceeds to S7-5.

  In S7-3, the layout unit 18 regenerates the content layout data. The control unit 2 displays the regenerated data on the display panel 4 b of the display unit 4. The processing for displaying content data here is the same as the content content data display processing in S2.

  In S7-4 when it is selected not to display the content data in S7-1, the layout unit 18 deletes the content layout data to be displayed. If the content layout data is deleted in this way, the content data to be displayed on the display unit 4 disappears, and the content is not displayed.

  In S7-5, the control unit 2 detects the selection as to whether or not to display the memo data with the operation unit 5. When the operation unit 5 detects an instruction to display, the process proceeds to S7-6. If the operation unit 5 detects an instruction to hide the memo data, for example, the process proceeds to S7-8.

  In S7-6, the layout unit 18 determines whether there is a change in the layout of the displayed memo data. If it is determined that the layout of the memo data is changed, it is necessary to redraw, and the process proceeds to S7-7. On the other hand, if there is no change in the layout of the memo data, the current layout may be displayed as it is, so the processing of S7-7 is omitted, all the display change processing is terminated, and the processing returns to S8 in FIG. .

  In S7-7, the layout unit 18 regenerates the memo layout data. The regenerated data is displayed on the display panel 4b of the display unit 4 by the control unit 2, and then the process ends, and the process returns to S8 shown in FIG. The process for displaying the memo layout data here is the same as the memo data display process in S5 of FIG.

  On the other hand, in S7-8 when it is selected not to display the memo data in S7-5, the layout unit 18 erases the memo layout data to be displayed. If the memo layout data is deleted in this way, the content of the memo data to be displayed on the display unit 4 disappears, so the memo data is not displayed. Thereafter, the process is terminated, and the process returns to S8 of FIG.

  The display state in the display device 1 can be changed by the processing described above.

  Next, a detailed example of the editing process shown in S9 of FIG. 18 will be described based on FIG.

  In S9-1, the editing control unit 12 of the editing unit 6 acquires the edited memo data. Here, it is assumed that memo data input from the operation unit 5 in accordance with a user operation / instruction is detected by the control unit 2 and acquired by the editing control unit 12 of the editing unit 6. The user operation / instruction includes, for example, an operation of adding handwritten data or text data. For example, an instruction to add an image or an instruction to delete memo data may be used.

  In S9-2, the memo area extraction unit 16 acquires the memo layout range of the memo data from the new memo data stored in the memo unit 14 by the editing control unit 12. The process for acquiring the memo layout range here is the same as the process for acquiring the memo layout range in S5-2.

  Next, in S9-3, the margin extraction unit 15 extracts a margin range in which the memo data can be laid out from the layout possible range obtained from the setting data 3c and the content layout range acquired from the content data. The margin range refers to an area where content data is not laid out, but is not limited to this, and may also refer to an area where neither content data nor already written memo data is laid out. Good.

  In S9-4, the comparison unit 17 compares the memo layout range acquired in S9-2 with the margin range acquired in S9-3. That is, whether the memo layout range is included in the margin range is compared, for example, in position and size.

  In S9-5, the comparison unit 17 determines whether or not the margin range needs to be changed based on the comparison result in S9-4. That is, when the memo layout range is included in the margin range, it is not necessary to change the margin range, and the process proceeds to S9-7. On the other hand, if the memo layout range is not included in the margin range, the process proceeds to S9-6.

  In S9-6, the layout unit 18 performs a margin range change process for changing the margin range, and proceeds to S9-7. The details of the margin range changing process will be described later.

  In S9-7, the layout unit 18 newly generates a layout of memo data.

  In step S9-8, the memo data with the layout set is displayed on the display panel 4b of the display unit 4. Thereafter, the process is terminated, and the process returns to S10 of FIG. Note that the memo data display process here is the same as the memo data display process in S5-4.

  According to the procedure described above, the screen display can be changed according to the editing operation.

  In the above-described embodiment, an example has been described in which memo data is handled without distinguishing between locations that have been included previously and locations that have been added this time. However, the present invention is not limited to this. For example, the editing unit 6 of the display device 1 may be configured to change the location only when there is an addition. Further, although an example has been described in which the display state is changed (S7) after receiving an instruction from the user regarding whether or not the display state of the displayed memo data is necessary (S6), the present invention is not limited to this. For example, the display state may be changed without waiting for an instruction from the user, such as automatically changing the resolution to an optimum resolution according to the setting.

  Next, a detailed example of the margin range change process described in S9-6 of FIG. 22 will be described based on FIG. Here, a case where memo data “→ handwritten, text” is added to the margin range 1702 shown in FIG. 12 will be described as an example.

  In S9-6-11, the layout unit 18 acquires, as the margin change range, the memo layout range when it is determined that the margin range needs to be changed in the process of S9-5 in FIG.

  Here, the margin change range means a memo layout range that protrudes from the margin range 1902 and includes the protruding portion 1903, such as a memo layout range 1901 shown in FIG.

  Here, the memo layout range 1901 is represented by coordinates (Xm1, Ym1) and (Xm2, Ym2) of two vertices. However, (Xm1 <Xm2, Ym1 <Ym2). The margin range 1902 is represented by coordinates (Xs1, Ys1) and (Xs2, Ys2) of two vertices. However, (Xs1 <Xs2, Ys1 <Ys2). Therefore, the memo layout range 1901 may be selected as the margin change range. In this case, the margin change range can be specified by vertex coordinates (Xm1, Ym1), (Xm2, Ym2).

  Further, the margin change range is not limited to the configuration indicating the memo layout range including the protrusion as described above. The margin change range may be configured to mean a protruding range 1903 as shown in FIG. In this case, the margin change range can be expressed by coordinates (Xs2, Ym1) and (Xm2, Ym2) of two vertices.

  Next, in S9-6-12, the layout unit 18 calculates a resolution for changing the margin range based on the margin range and the margin change range. Specifically, for example, the resolution may be changed so as to expand the margin range so that the entire margin change range fits in the margin range.

  In S9-6-13, the layout unit 18 acquires a content layout range in order to regenerate the layout based on the resolution calculated in S9-6-12.

  In S9-6-14, the layout unit 18 generates new content layout data whose resolution has been changed.

  In S9-6-15, the content layout data generated by the layout unit 18 in S9-6-14 is displayed on the display panel 4b of the display unit 4. Thereafter, the process ends, and the process proceeds to S9-7 in FIG.

  As described above, the margin range can be changed by changing the resolution.

  Here, FIG. 1 shows a detailed example of the display of the editing process for adding memo data in the display device 1 of the present embodiment. FIG. 1 shows a case where memo data “→ handwritten, text” is added horizontally to the margin range 1702 shown in FIG.

  A range 2501 surrounded by a bold line is a content layout range. A range 2502 and a range 2503 are content layout ranges after resolution expansion when writing is performed in the margins of the ranges 2501 and 2502, respectively. A range 2504, a range 2505, and a range 2506 surrounded by a broken line are blank ranges in the content layout ranges 2501, 2502, and 2503, respectively. The corresponding memo layout range is not shown.

  In the content layout range 2501, the memo layout range is included in the margin range 2504 until the memo data “→ handwritten” is added. For this reason, there is no change in the display of content data.

  If an attempt is made to add “→ handwritten, te” as memo data to the margin range 2504, the memo data “te” portion is not included in the margin range 2504. Therefore, the resolution of the content data is changed, and the content layout range 2501 is changed to the content layout range 2502. As a result, the margin range 2504 is changed to the margin range 2505, and the memo data “→ handwritten, te” is included in the margin range 2505.

  If an attempt is made to add “→ handwriting, text” as memo data to the margin range 2505, the memo data “ki” portion is not included in the margin range 2505. Therefore, the resolution of the content data is further changed to change from the content layout range 2502 to the content layout range 2503. As a result, the margin range 2505 is changed to the margin range 2506, and the memo data “→ handwritten, text” is included in the margin range 2506.

  By continuing these processes, a sufficient amount of memos can be recorded in the margin of the content, and the display device 1 that is convenient for recording can be obtained.

  Here, in the example shown in FIG. 1, memo data is added horizontally by the user. For this reason, the protruding range in which the memo layout range protrudes from the content layout range protrudes not in the Y direction indicated by Yp in FIG. 1 but in the X direction orthogonal to the Y direction. In such a case, if the Y-direction distance Yp shown in FIG. 1 is fixed, that is, the position of the margin range in the Y-direction is fixed, even if the resolution is changed according to the addition of the memo data, the memo data The position in the Y direction to add is fixed. For this reason, the user can add a memo only in the X direction. Therefore, the usability of the display device 1 when adding memo data continuously can be further improved.

  In the above-described example described with reference to FIG. 1, the configuration in which the resolution of the content data is increased in order to expand the margin range with the addition of memo data has been described. However, the present invention is not limited to this. .

  For example, when the editing unit 6 of the display device 1 performs the editing process for deleting the memo data, it is not the processing in the order of the ranges 2501, 2502, and 2503 shown in FIG. , 2502 and 2501 are processed. That is, when the memo data is deleted, for example, it is determined that the ratio of the memo layout range shown in the margin range is smaller than a certain value, and the layout unit 18 of the editing unit 6 changes the margin range. Thus, the margin range is reduced by reducing the resolution of the content data so that the margin range has a size suitable for including the memo data.

  Further, the resolution magnification which is changed by the layout unit 18 is not limited to the magnification β obtained as described above, and for example, an arbitrary value may be added to the calculated value β. For example, when the resolution is increased, a predetermined value is added to the calculated value β, which is the calculated value, and a value larger than the calculated value is set as the resolution, so that a large margin area with a margin is obtained. Can do. Similarly, when the resolution is lowered, a large margin range with a margin can be obtained by setting a value smaller than the calculated value as the resolution.

  The editing unit 6 of the display device 1 is not limited to the above-described configuration, and the resolution of the content data may be lowered with the addition of memo data, for example, according to the setting of the setting data 3c. For example, when the resolution is high and the resolution magnification for storing the memo data in the margin is β, the resolution magnification may be 1 / β times. In this case, if the current resolution is R, the resolution is changed to R / β.

  An example of lowering the resolution with the addition of memo data will be described with reference to FIG. FIG. 24 shows a case where memo data “→ handwritten, text” is added horizontally to the margin range 1702 in FIG.

  A range 2701 surrounded by a thick line shown in FIG. 24 is a content layout range. A range 2702 and a range 2703 are content layout ranges when the resolution is lowered in accordance with the writing to the margin. A range 2704, a range 2705, and a range 2706 surrounded by a broken line are blank ranges in the content layout ranges 2701, 2702, and 2703, respectively. The corresponding memo layout range is not shown.

  In the content layout range 2701, the memo layout range is included in the margin range 2704 until the memo data “→ handwritten” is added. For this reason, there is no change in the display of content data.

  If an attempt is made to add “→ handwritten, te” as memo data to the margin range 2704, the memo data “te” portion is not included in the margin range 2704. For this reason, the resolution of the content data is lowered and the content layout range 2701 is changed to the content layout range 2702. As a result, in the content layout range 2701 or 2702 in which the content can be laid out, the area actually occupied by the content is reduced. On the other hand, there is no change in the layout range in which data can be laid out. For this reason, even by reducing the resolution in this way, the margin area 2704 can be changed to the margin area 2705 and the size of the margin area can be enlarged. Thus, the memo data “→ handwritten, te” is included in the margin range 2705.

  If an attempt is made to add “→ handwriting, text” as memo data to the margin range 2705, the memo data “ki” portion is not included in the margin range 2705. For this reason, the resolution of the content data is further changed to change from the content layout range 2702 to the content layout range 2703. As a result, the margin range 2705 is changed to the margin range 2706, and the memo data “→ handwritten text” is included in the margin range 2706.

  By continuing these processes, it is possible to change the margin range of the content data and record a sufficient amount of notes in the margin of the content. For this reason, the display device 1 that is convenient for recording can be obtained.

  In the editing process described above, the content data is only displayed and the editing of the content data has not been described. However, the present invention is not limited to this. In FIG. 18, processing for determining whether to edit content data and processing for editing content data may be added before the processing for determining whether to edit memo data in S8. The content data editing process may be a generally known editing method.

[Modification 1]
In the above-described embodiment, the display device 1 configured to change the resolution of the content data in order to appropriately display the memo data has been described. However, the present invention is not limited to this. For example, the data element interval of the content data is changed. It may be configured to.

  A modification of the display device 1 will be described with reference to FIGS. In the modification described below, members having the same functions as those of the display device 1 in the above-described embodiment are denoted by the same reference numerals and description thereof is omitted.

  In this modification, for example, text (TEXT) data is handled as content data. In addition, each character of the text is treated as an independent element (data element). And the space | interval which arranges each data element is adjusted so that it may mention later.

  An example of the memo data 3b in this case is a data configuration in which the change information item includes a pointer to the interval (LX, LY) of the display target elements as shown in FIG. In response to this, the display target elements 701, 702, and 703 of each memo data are displayed in a state where surrounding content data is arranged according to the element interval (LX, LY) for each display target element.

  If the surrounding content data is arranged at an appropriate element interval in this way, the margin range of the content can be appropriately sized accordingly, and for example, the size can be appropriately included in the memo layout range. it can. In addition, if the element spacing in the display target element of the content data is held in this way, the relationship between the size of the memo data and the size of the margin range that includes the memo data can be held.

  The interval LX means an interval in the X direction, and the interval LY means an interval in the Y direction. When the content data is displayed horizontally, the line spacing corresponds to the Y-direction spacing, and the adjacent character spacing corresponds to the X-direction spacing. Further, the position X, the position Y, the width W, and the height H may be information based on the state before changing the interval between the display target elements of the content data, or based on the state after the change. It may be information.

  Here, when content data is handled as a display target element and each character is handled as an independent element, an example of a margin range obtained from the content data is as shown in FIG. FIG. 26 is a diagram illustrating a margin between display target elements of horizontally written content data composed of full-width kana display target elements. FIG. 26 shows an enlarged portion of the second and third lines of the content data shown in FIG. A hatched range 1101 and a range 1102 surrounded by a broken line are a margin range between display target elements representing characters (the width corresponds to LX), and a margin range between lines represented by the display target elements (width is Corresponds to LY). These correspond to extending the concept of the margin range of the rectangular range in the above-described embodiment.

  Next, an operation for changing the layout of the content data as the memo data is added will be described with reference to FIGS. A method for calculating the interval between display target elements for changing the margin range will be described.

  FIG. 27 shows a state where handwritten data is further added to the state shown in FIG. In the margin range 2302 surrounded by a broken line (corresponding to the margin range 1802 in FIG. 13), the memo layout range of a rectangular range including the memo data “→ handwritten, te” is as a range 2301 surrounded by a thin line. Here, in FIG. 27, the interval (LX) between the display target elements of the content data is shown as L1 for the interval between the display target elements “large” and “ki” as an example.

  By adding the memo data in this way, a range 2303 indicated by hatching in the memo layout range 2301 protrudes from the margin range 2302 as shown in FIG. For this reason, the editing unit 6 of the display device 1 compares the memo layout range newly modified with the addition of the memo data with the corresponding margin range, and changes the layout of the content data.

  FIG. 28 shows a state after the layout of content data is changed from the written state as shown in FIG. In FIG. 28, each interval between the display target elements of the content data after the layout change is shown as L2 by taking an interval between the display target elements “large” and “ki” as an example. As a result, the margin range 2302 shown in FIG. 27 is changed to the margin range 2402 shown in FIG. A range 2401 surrounded by a thin line is a memo layout range, and is laid out so as to be within a margin range 2402 indicated by a broken line.

  Here, in FIG. 27, the margin range 2302 is specified by coordinates (Xs1, Ys1) and (Xs2, Ys2) of two vertices. However, (Xs1 <Xs2, Ys1 <Ys2). Further, the protruding range 2303 is specified by coordinates (Xs2, Ym1) and (Xm2, Ym2) of two vertices. However, (Xs1 <Xm1 <Xs2 <Xm2, Ys1 <Ym1 <Ym2 <Ys2).

  In FIG. 28, the changed margin range 2402 is designated by the coordinates (Xs5, Ys5) and (Xs6, Ys6) of the two vertices. However, (Xs5 <Xs6, Ys5 <Ys6).

  The change amount of the display target element interval for changing the margin range is set so that the margin range 2402 after the change includes the memo layout range 2401.

  First, in FIG. 27, a rectangular range including a margin range 2302 and a protruding range 2303 can be indicated by coordinates (Xs1, Ys1) and (Xm2, Ys2) of two vertices. This range is hereinafter referred to as the inclusion range.

In order to obtain the inclusion range by changing the position and size of the margin range 2302, the size of the margin range 2302 may be changed in the X direction and increased. The condition in the case where the inclusion range matches the changed margin range 2402 in FIG. 28 is as follows: the inclusion range is compared with the changed margin range 2402 in the X direction;
(Xs6-Xs5) = (Xm2-Xs1) (7)
If it becomes.

In order to appropriately increase the size of the margin range 2302 in the X direction, the character interval L1 of the content data may be increased by the interval γ to L2. That is, L2 = L1 + γ. Here, if the increase γ of the interval is changed equally for each interval for each display target element,
(Xs6-Xs5)
= (Xs2−Xs1) + γ × (number of intervals of display target elements in X direction) Equation (8)
Holds.

From the two equations (7) and (8), the value of the interval γ is
γ = ((Xm2−Xs1) − (Xs2−Xs1)) /
(Number of intervals between display target elements in the X direction) Expression (9)
Is obtained. If the interval between the display target elements of the content data is increased by the increase γ thus obtained, a margin range 2402 having an appropriate size including the memo layout range 2401 can be obtained as shown in FIG. Further, the value of L2 obtained as L2 = L1 + γ is stored in the item “LX” of the memo data 3b shown in FIG.

  Note that the interval between the display target elements of the content data to be changed may be increased by a value obtained by adding an arbitrary value to the calculated value γ. For example, by setting a value larger than the calculated value as the interval between the display target elements, a large margin range with a margin can be obtained.

  Further, in the display device 1 of this modification, the editing procedure when adding memo data is substantially the same as the procedure described based on FIGS. 18 to 23 in the above-described embodiment. However, the difference is that the margin range changing process of S9-6 shown in FIG. 22 described based on FIG. 23 is replaced with a procedure described below based on FIG.

  FIG. 30 shows an example in which memo data “→ handwritten, text” is added to the margin range 1702 shown in FIG. In the margin range change process in this modification, in S9-6-21, the layout unit 18 acquires a range that is determined to require a change in the margin range in the process of S9-5 in FIG. 22 as a margin change range. The process for acquiring the margin change range here is the same as the process for acquiring the margin change range in S9-6-11 in FIG.

  Next, in S9-6-22, the layout unit 18 calculates the interval between the display target elements for changing the margin range based on the margin range and the margin change range. Specifically, for example, the interval between the display target elements may be changed so that the margin range is expanded so that the entire margin change range is within the margin range.

  In S9-6-23, the layout unit 18 acquires the content layout range in order to regenerate the layout based on the interval between the display target elements calculated in S9-6-22.

  In S9-6-24, the layout unit 18 generates new content layout data in which the interval between the display target elements is changed.

  In S9-6-25, the content layout data generated by the layout unit 18 in S9-6-24 is displayed on the display panel 4b of the display unit 4. Thereafter, the process ends, and the process proceeds to S9-7 in FIG.

  As described above, the margin range can be changed by changing the interval between the display target elements.

  Next, a specific example of the margin range changing process described with reference to FIGS. 27, 28, and 30 will be described with reference to FIG. FIG. 29 shows an example in which memo data “→ handwritten, text” is added to the margin range 1702 shown in FIG.

  A range 2801 surrounded by a bold line is a content layout range. A range 2802 and a range 2803 are content layout ranges after the interval of the display target elements is changed when writing is performed in the margins of the ranges 2801 and 2802, respectively. A range 2804, a range 2805, and a range 2806 surrounded by a broken line are blank ranges in the content layout ranges 2801, 2802, and 2803, respectively. It should be noted that a range 2807 and a range 2808 surrounded by thin lines are illustrated for the sake of convenience so that the interval between the display target elements of the content data can be understood.

  In the content layout range 2801, the memo layout range is included in the margin range 2804 until the memo data “→ handwritten” is added. For this reason, there is no change in the display of content data.

  If an attempt is made to add “→ handwritten, te” as memo data to the margin range 2804, the memo data “te” portion is not included in the margin range 2804. For this reason, the interval between the display target elements of the content data is changed so that the content in the content layout range 2801 covers the range 2807, and the content layout range 2801 is changed to the content layout range 2802. As a result, the margin range 2804 is changed to the margin range 2805, and the memo data “→ handwritten, te” is included in the margin range 2805.

  If an attempt is made to add “→ handwriting, text” as memo data to the margin range 2805, the memo data “ki” portion is not included in the margin range 2805. Therefore, the content layout range 2802 is changed to the content layout range 2803 so that the interval between the display target elements of the content data is further changed so that the content in the range 2807 covers the range 2808. As a result, the margin range 2805 is changed to the margin range 2806, and the memo data “→ handwritten, te” is included in the margin range 2806.

  If these processes are continued, in the content layout range 2803, the memo data “→ handwritten, text” is included in the margin range 2806. At this time, the intervals between the display target elements of the content data are as shown in a range 2808.

  In FIG. 29, the memo data is added in horizontal writing, so that the protrusion range caused by adding the memo data does not normally exist in the Y direction indicated by Yp in the figure, and the X direction orthogonal to the Y direction. Will exist. Therefore, in such a case, as indicated by Yp in FIG. 29, the position of the margin range in the Y direction is not changed.

  Therefore, even when memo data is continuously added, the position in the Y direction to be added does not shift. For this reason, the user can add only in the X direction, and can add memo data continuously.

[Modification 2]
In the above-described embodiment, the case where the content data is written horizontally in Japanese has been described, but the present invention is not limited to this. The content data may be vertically written, for example, or may be English, for example.

  First, a modification of the display device 1 that handles vertically written content data will be described with reference to FIGS. In the modification described below, members having the same functions as those of the display device 1 in the above-described embodiment are denoted by the same reference numerals and description thereof is omitted.

  FIG. 31 is a diagram showing vertically written content data that is displayed on the display panel 4b of the display device 1 and that is composed of display target elements of full-width kana. A range 3901 surrounded by a thick line is a content layout range. In the content layout range 3901, the display target element of content data “Because there is a limit to margins” is displayed.

  FIG. 32 is a diagram showing a margin range around the content data shown in FIG. A range 4001 surrounded by a thick line is a content layout range, and a hatched range 4002 surrounded by a thick line and a broken line is a margin range 4002. The margin range 4002 is arranged between the content layout range 4001 and the content data display target element.

  FIG. 33 is a diagram showing selection of a margin range different from the configuration shown in FIG. FIG. 33 shows the margin of the rectangular range of vertically written content data composed of the display elements of full-width kana in FIG. A range 4101 surrounded by a bold line is a content layout range, and a hatched range 4102, a range 4103, and a range 4104 surrounded by a broken line correspond to a margin range.

  In this way, for example, the margin range is extracted from the content range shown in FIG. 31 as shown in FIG. 32 or FIG. When editing the memo data with respect to the extracted margin range, the margin range is changed so that the margin range suitable for the memo data is obtained by the procedure described in the above embodiment. be able to.

  FIG. 34 is a diagram showing a margin between display target elements of vertically written content data for the display target elements shown in FIG. FIG. 34 is an enlarged view of a part of the third and fourth lines in FIG. In FIG. 34, a hatched range 4201 surrounded by a broken line indicates a blank range between display target elements representing characters, and a range 4202 indicates a blank range between lines represented by display target elements.

  In this way, for example, the margin range is extracted from the content range shown in FIG. 31 as shown in FIG. When editing the memo data for the extracted margin range, the inside of the margin range is changed so that the margin range suitable for the memo data is obtained by the procedure described in the above modification. Can do.

  As described above, even when vertically written data is used, as shown in FIG. 31 to FIG. 34, the margin range associated with the editing of the memo data is changed based on the configuration of the display device 1 described above. Therefore, operability can be improved.

  Next, a modification of the display device 1 that handles English content data will be described with reference to FIGS.

  FIG. 35 is a diagram showing content data composed of half-width alphanumeric display target elements displayed on the display panel 4 b of the display device 1. A range 1201 surrounded by a bold line is a content layout range. A content data display target element “We cant make” is displayed in the content layout range 1201.

  FIG. 36 is a diagram showing a margin range around content data composed of the display target elements of single-byte alphanumeric characters of FIG. A range 1301 surrounded by a bold line is a content layout range 1301. A hatched area 1302 surrounded by a bold line and a broken line indicates a margin area.

  FIG. 37 shows a margin range in a format different from that shown in FIG. 36 of the content data composed of half-width alphanumeric display target elements shown in FIG. A rectangular margin range 1042 can be stored in the margin of the content layout range 1401.

  Thus, for example, the margin range is extracted from the content range shown in FIG. 35 as shown in FIG. 36 or FIG. When editing the memo data with respect to the extracted margin range, the margin range is changed so that the margin range suitable for the memo data is obtained by the procedure described in the above embodiment. be able to.

  Also, FIG. 38 shows margins between the display target elements of the content data for the single-byte alphanumeric display target elements shown in FIG. FIG. 38 is an enlarged view of a part of the third and fourth lines in FIG. A hatched range 1501 surrounded by a broken line indicates a margin range between display target elements representing characters. A hatched range 1502 surrounded by a broken line indicates a margin range between the lines represented by the display target elements.

  Even in the case of the English contents shown in FIGS. 35 to 38 described above, the operability can be improved by changing the margin range accompanying the editing of the memo data based on the configuration of the display device 1 described above.

  Further, when the above-described editing process is performed, the content data that is the display target element does not need to be arranged in rows and columns as in the examples illustrated in FIGS. 8, 31, and 35. Even content data in which a display target element is arranged at an arbitrary position can be edited in the same manner as in the above example.

[Modification 3]
In the above-described embodiment, the case where the memo data to be added is written horizontally is described. However, the present invention is not limited to this. For example, the memo data may be written vertically.

  A modification of the display device 1 that handles vertically written memo data will be described with reference to FIGS. In the modification described below, members having the same functions as those of the display device 1 in the above-described embodiment are denoted by the same reference numerals and description thereof is omitted.

  The display device 1 of the present modification is similar to the above-described embodiment in that the editing process described with reference to FIGS. 18 to 22 is executed. The margin range changing process of S9-6 in FIG. 22 accompanying the addition of vertically written memo data will be described based on FIG.

  As an example, FIG. 39 shows a case where memo data “→ handwritten” is added vertically to the margin range 1702 shown in FIG. 12 and the resolution of the content data is changed in accordance with the addition.

  A range 2601 surrounded by a thick line is a content layout range. A range 2602 indicates a content layout range when the resolution of the content layout range 2601 is increased. A range 2603 indicates a content layout range when the resolution of the content layout range 2602 is increased. A range 2604, a range 2605, and a range 2606 surrounded by a broken line are blank ranges in the content layout ranges 2601, 2602, and 2603, respectively.

  The content layout range 2601 indicates a state in which the memo data “→ hand” is included in the margin range 2604. The content layout range 2602 indicates a state in which the memo data “→ handwriting” is included in the margin range 2605. The content layout range 2603 indicates a state in which the memo data “→ handwritten” is included in the margin range 2606. As in the case where the memo data is written horizontally, the margin range is increased by increasing the resolution of the content data so as to include the memo layout area as the memo data is added. Since the flow of such processing is the same as when writing memo data horizontally, description thereof is omitted here.

  In the example shown in FIG. 39, since the memo data is added vertically (Y direction), the memo layout area becomes longer in the Y direction as the memo data is added. For this reason, the protruding range in which the memo layout area protrudes from the margin area does not exist at the position in the X direction from the memo layout area but exists at the position in the Y direction. Therefore, in the editing unit 6 of the display device 1, the position in the X direction of the margin range that is changed with the change of the resolution is set to a fixed position as indicated by Xp in FIG. 9, for example. In this way, when adding memo data, the position in the X direction does not shift even if the margin range is changed with the resolution change. For this reason, the user can add only in the Y direction, and can easily add memo data continuously.

  Next, as another example, based on FIG. 40, the memo data “→ handwritten” is added vertically in the margin range 1702 shown in FIG. 12, and the interval between the display target elements of the content data is changed according to the addition. The case where it does is demonstrated.

  A range 2901 surrounded by a thick line is a content layout range. A range 2907 indicates a range when the interval between the display target elements is widened with respect to the content layout range 2901. Of these, the range 2902 is the content layout range in this case. A range 2908 indicates a range when the interval between display target elements is widened with respect to the range 2907, and a range 2903 is a content layout range in this case. A range 2907 and a range 2908 are ranges shown for convenience so that the interval between the display target elements of the content data can be understood. A range 2904, a range 2905, and a range 2906 surrounded by a broken line are blank ranges in the content layout ranges 2901, 2902, and 2903, respectively.

  The content layout range 2901 indicates a state in which the memo data “→ hand” is included in the margin range 2904. The content layout range 2902 shows a state where the memo data “→ handwriting” is included in the blank range 2905. The content layout range 2903 indicates a state where the memo data “→ handwritten” is included in the margin range 2906. As in the case where the memo data is written horizontally, the margin range is increased by increasing the interval between the display target elements of the content data so as to include the memo layout area as the memo data is added. Here, in particular, the line spacing in the Y direction is increased while keeping the character spacing in the X direction constant.

  In FIG. 40, since the memo data is added vertically, the protrusion area of the memo layout area from the margin area that occurs when the memo data is added is located at the position in the X direction from the memo layout area. It does not exist and exists at a position in the Y direction. For this reason, even when the margin range is enlarged with the addition of the memo data, it is not necessary to change the position of the margin range in the X direction, as indicated by the position Xp in FIG. Therefore, when adding memo data, the display device 1 does not shift the position of the margin range in the X direction, so that the user can add the conscious data only in the Y direction. The user can easily add memo data continuously.

  In the above-described embodiment and modification, the example in which the intervals of the display target elements of the content data are changed at equal intervals including FIG. 40 has been described, but the present invention is not limited to this. . A configuration may be employed in which the intervals between the display target elements of the content data are changed not unevenly but unevenly. Modification examples of the display device 1 in this case will be described based on FIGS. 41 and 42, respectively.

  FIG. 41 shows a case where content data “→ handwritten” is added to vertical writing in the content layout range 2901 of FIG. Here, in FIG. 41, the interval between the display target elements of the content data is changed in a format different from the content layout ranges 2902 and 2903 of FIG. That is, the interval between the display target elements of the content data is changed by a different amount depending on the distance from the margin range. In particular, the closer the distance from the margin range, the greater the amount by which the interval is changed. More specifically, the interval between the display target elements of the content data is changed only for the portion in contact with the margin range. Further, the portions where the interval is changed are changed at equal intervals.

  In FIG. 41, a range 3001 surrounded by a bold line is a content layout range, and a range 3002 surrounded by a broken line is a margin range. For the margin range 3002 in which the length in the Y direction is L3, the interval between the display target elements at locations in contact with the margin range 3002 (before and after the margin range 3002) is changed to L4. In other places, the interval was left as it was before the memo data was added.

  FIG. 42 shows another example in which content data “→ handwritten” is added to vertical writing in the content layout range 2901 of FIG. In this example, unlike the example shown in FIG. 41, when there are a plurality of portions in contact with the margin range among the intervals of the display target elements, they are not changed equally but are changed at unequal intervals.

  In FIG. 42, a range 3101 surrounded by a bold line is a content layout range, and a range 3102 surrounded by a broken line is a margin range. With respect to the margin range 3102 whose length in the Y direction is L5, the interval on the front side of the portion in contact with the margin range 3102 is not changed, and the interval on the rear side is changed to L6. In other places, the interval remains the same as before the memo data was added.

  As described above, the present invention relates to an editing method, an editing device, an editing program, and a recording medium on which the editing program is recorded, which can be recorded continuously without minding the size of a memo. For example, when it is determined that the size of the memo exceeds the margin range, the margin range is enlarged by changing the resolution of the content naturally so that the memo can be continued. Alternatively, the margin range can be increased by changing the spacing between the characters of the content and the spacing between lines so that the memo can be continued. Further, the layout of the content data is changed while the memo data layout is maintained, and the margin range is expanded / reduced. This eliminates the need to worry about the size of the memo and allows continuous recording. Also, as a result, the margin range becomes large, so that a memo can be recorded sufficiently. Therefore, it is possible to provide an editing method, an editing apparatus, an editing program, and a recording medium on which the editing program can be recorded.

  In the above-described embodiment, only the case where the content data margin range is changed in order to change the relative size between the content data margin range and the memo data layout range has been described. However, the present invention is not limited to this. For example, the configuration may be such that the relationship between the margin range of the content data and the layout range of the memo data is changed by changing the layout of the memo data, such as when the resolution of the memo data is lowered. However, if the margin range of the content data is changed and the layout range of the memo data is not changed, the position and size of the memo data do not change, so that the memo data can be easily added.

  Moreover, as a recording medium which records the program for implement | achieving the edit part 6 of the display apparatus 1, a floppy disk, a hard disk, an optical disk, a magneto-optical disk, a magnetic tape, a non-volatile memory card etc. are used, for example. Can do. Alternatively, the program may be downloaded from another computer system to the recording medium or an external storage including the recording medium via a transmission medium such as a communication network.

  Further, as described above, not only the editing unit 6 but also the control unit 2 is realized by a program. For this reason, for example, an OS (operating system) running on the display device 1 may perform a part or all of the actual processing in the editing unit 6 as well as the processing of the control unit 2. Alternatively, after the program read from the recording medium is written in the memory provided in the function expansion board inserted into the computer or the function expansion unit connected to the computer, the function expansion board is based on the instructions of the program. Alternatively, the CPU or the like provided in the function expansion unit may perform part or all of the actual processing, and the functions of the above-described embodiments may be realized by the processing.

  In the above-described embodiment, the configuration in which the display unit 4 and the editing unit 6 of the display device 1 are integrated has been described. However, the present invention is not limited to this. The display device 1 as the output device and the editing unit 6 may be separate. For example, the editing device including the editing unit 6 may be connected to a display device serving as an output device including a display panel as an output medium.

  The specific embodiments or examples described above are merely to clarify the technical contents of the present invention, and the present invention is not limited to such specific examples and should not be interpreted in a narrow sense. Various modifications are possible within the scope shown in the claims, and the technology of the present invention also applies to the modified embodiments and the embodiments obtained by appropriately combining the technical means disclosed in the embodiments.
