Description

  The present invention generally relates to a content display device, and more specifically, marks a part of a display area of an electronic book and presents the marked area as a worm-eaten (mask) according to various conditions. The present invention relates to a content display device improved so that The present invention also relates to a program for causing a computer to realize such worm-eating (mask) display and a storage medium storing the program.

  Conventionally, as shown in FIG. 18, an electronic book apparatus has been proposed that can draw a line in a sentence or write a memo or graffiti (Patent Document 1). With reference to FIG. 18, the electronic book apparatus reads desired book data from the storage medium 10 via the storage medium control unit 9 and displays it on the display unit 7. The user specifies a writing range such as underline or marking in the book data displayed on the display unit 7 by the key input unit 2. In addition, the pen input unit 3 is used to draw an arbitrary content such as a mark on the book data and write the non-text data. The memory 5 stores write data. When there is a display request for the writing portion by the key input unit 2, the display control unit 6 converts the writing data stored in the memory 5 and the book data held in the storage medium 10 into frame data and displays it. Part 7 is given. Marks have a concept of ranking on the screen display (like a layer). By changing the display order, the mark is displayed below the text (marker function), and the mark is displayed above the text ( (Mask-like appearance) can be realized.

  Further, by switching between a writing mode on the page and a mode of turning / pasting a sticky note on a worm-eating, an information display device and an electronic book having functions that are convenient for learning and the like are eliminated. An apparatus has also been proposed (Patent Document 2). This is mainly intended to add a mode for controlling the display of content-embedded display [mask (worm-eaten), user-set mask, no mask display, user-written data such as ruled lines and graffiti]. For example, the mask to be displayed is changed according to the conditions, such as displaying only the user setting mask, displaying only the built-in mask, and displaying all masks. In Patent Document 2, what is described as a marker is information (ruled lines, handwritten memos, etc.) corresponding to a memo drawn by a user, and ON / OFF of the information is similarly controlled.

  However, in the disclosed technique of Patent Document 1, information indicating the display order can be given to additional data other than the displayed text, and the display characters can be hidden by raising the display order of the mark (one case). However, there is a problem that it cannot be used as a general mask function, such as displaying only a predetermined mask in a different order when clicked.

  Also, in the disclosed technique of Patent Document 2, various combinations of user setting writing and display / non-display of functions incorporated in contents can be changed, but each function cannot be changed and used, and what is marked Only displayed as a mark. For this reason, when an attempt is made to mask the marked object, it is necessary to create a mask again, which is troublesome and requires holding each information, resulting in a problem of consuming memory.

  The present invention has been made to solve such problems, and it is possible to mark a part of the display area of an electronic book and present the marked area as a worm-eaten (mask) according to various conditions. It is an object of the present invention to provide a content display device improved so as to be able to do so.

  According to a preferred embodiment of the present invention, the additional information is given a predetermined maximum value (Max Level) at the time point when the user marks, and is decremented every time the content is opened. The value of the designation information that is arbitrarily specified in advance including the mark level (ML) is a set value (VL) for switching to the mask function, and the designated area function switching means is configured to switch the mark level (ML) to the mark level (ML). When the set values (VL) are compared and they match, the designated area function switching means switches the marked area to the mask function, and the designated area display means switches the marked area. The mask is displayed as an insect eater.

  There may be further provided means for returning all the worm-eating displays to the marks and displaying them. This is to return to the mark state so that the information added to the mark can be updated.

  Further, preferably, the set value (VL) for switching to the mask function can be arbitrarily set, thereby marking the previously marked area or before / after the number of times arbitrarily designated by the user. The displayed area can be changed so that the area is masked and displayed according to the user's intention.

  Preferably, the display form can be changed according to the value of the mark level (ML) even for a mark that is not displayed by masking. The display form of the mark is preferably a color depth. The display form of the mark may be a character size. The display form of the mark may be the thickness of the character.

  The mark level (ML) is preferably set such that the mark level value can be set by toggling between a new mark and an original state by clicking an existing mark.

  Preferably, the additional information includes a mark creation date and time (MD) given to the marked area, and the value of the arbitrarily specified designation information is the date and time information (VD) for switching to the mask function. And the designated area function switching means compares the mark creation date and time (MD) with the value of the date and time information (VD), and if the condition is satisfied, the designated area function switching means is marked as described above. The designated area display means masks the marked area and displays it as a worm-eaten.

  In addition, it is possible to arbitrarily set the date and time information (VD) to be changed to a mask, so that it is masked and displayed according to the user's intention, such as a mark for N month D, a mark after M month D, etc. It is also possible to change the area to be changed.

  In addition, the display form may be changed for marks that are not displayed as masks according to the date and time of mark application. The display form of the mark is preferably a color depth. The display form of the mark may be a character size. The display form of the mark may be the thickness of the character.

  It is preferable that the mark assignment date and time can be set by toggling between the new mark and the original state by clicking on an existing mark.

  Preferably, the additional information includes mark number information (MT) indicating the number of times the mark is added to the marked area, and the value of the arbitrarily designated designation information is switched to the mask function. Mark number information setting value (VT) for the case, and the designated area function switching means compares the mark number information (MT) with the mark number information setting value (VT) and satisfies the condition The designated area function switching means may switch the marked area to a mask function, and the designated area display means may mask the marked area and display it as a worm-eaten.

  Further, it is possible to arbitrarily set the mark number information setting value (VT), which is a setting value to be changed to a mask, thereby masking according to the user's intention such as N marks, N marks or more. The displayed area may be changed.

  In addition, the display form of a mark that is not displayed as a mask may be changed according to the value of the number of marks. The display form of the mark is preferably a color depth. The display form of the mark may be a character size. The display form of the mark may be the thickness of the character.

  It is preferable that the mark number information (MT) can be increased by clicking on an existing mark and increasing the value of the mark number of times.

  The additional information includes mask display flag information (MF) added by the user, and the value of the specified information arbitrarily specified in advance is a set value (ON (1)) for switching to the mask function. The designated area function switching means compares the mask display flag information (MF) with the set value (ON (1)), and if they match, the designated area function switching means is marked as described above. Preferably, the designated area is switched to the mask function, and the designated area display means masks the marked area and displays it as a worm-eaten.

  It is preferable that the mask display flag (MF) can be set by toggling the ON / OFF state of the mask display flag by clicking an existing mark.

  Mark function, mask for the purpose of obtaining a content display device improved so that a part of the display area of an electronic book can be marked and the marked area can be presented as a worm-eaten (mask) according to various conditions Each function is used as a separate function, and the mark function and the mask function are switched according to various conditions. The various conditions refer to the elapsed time since marking, the color of the mark, the number of marks, arbitrary settings, and the like. Mark and mask data are held as common data.

  FIG. 1 is a block diagram showing a configuration of a content display apparatus according to an embodiment of the present invention. Referring to FIG. 1, the content display device includes an overall control unit 11 and a display unit 12. The overall control unit 11 is composed of a CPU. When the content is displayed on the display unit 12 on the display unit 12, the overall control unit 11 designates (selects) an arbitrary area and marks it with an area designating unit 11a and an addition to the marked area. An additional information adding unit 11b for adding information, a designated area function switching unit 11c for switching the function of the marked area by comparing the additional information with a value of designation information arbitrarily designated in advance by the user, There is provided designated area display means 11d for displaying the marked area based on the switched function.

  According to the content display device of the present invention, a flexible mark / mask switching mechanism according to setting conditions can be realized, and a user can give a mark as a learning memo without being conscious of the mark / mask, depending on the mood. Books can be used in various learning forms, such as changing as a mask. Further, it is not necessary to have data for the mask and the mark, and the memory can be saved. The operation of the embodiment of the present invention will be described below with reference to the drawings.

  2 and 3 are diagrams for explaining a partial operation of the content display apparatus according to the first embodiment that performs mask display in accordance with the set additional information “number of book open after marking (N)”. 2 shows the case of “area selection”, and FIG. 3 shows the case of “display”. FIG. 4 and FIG. 5 show a processing flow in which mask display is performed according to the set additional information “number of book opening after marking (N)”, and only the previously marked one is masked. FIG. 6 shows a processing flow for performing mask display according to the set additional information “number of book open after marking (N)” and a processing flow for masking only those marked after the specified number of times. The operation will be described with reference to these drawings.

(Marking)
As an example, consider an operation when an electronic book viewer implemented as application software on a PC is used. In a situation where a book is opened and displayed on an electronic book or the like, the user can give a mark. The user sets a selection area using a mouse for an area in which the user is interested or an important word or phrase when used for learning. The operation is the same as the selection of a copy area of a generally used text editor. After selecting an area, “Copy”, “Mark”, etc. are presented as context menus, and the mark area can be set (designated).

  If the set area is a newly set area, the area information (position information in the text, mark color information, mark level (ML)) is saved for each area, and the newly set mark area is stored. Mark and display with a defined color.

If the set area is not a newly set area, or if a click is made on an area that is displayed in advance as a mark area, the mark level of the target area and a threshold value set in advance by the user ( Max Level) and if it matches, set the stored value (OLDML) stored in advance to ML, and if it does not match, save the current level as OLDML, then Max Set Level to ML. This makes it possible to control the mark level by clicking or the like, and it becomes possible to perform operations such as setting the latest mark level for what has been marked before but still seems important. Depending on the object, it is possible to always store the level as the maximum value.

  The area information thus set is stored as information in a file or the like.

(Mask)
The operation when displaying as a mask is as follows.
At the same time as reading the book data, the area information created at the time of marking is read, and the mark is displayed according to the area information. At this time, the read mark level is set to “−1”, and the mark level is set to Max for the mark created at the previous opening. Level-1.
If there is no selection area in the display page, do nothing and display based on the information in the book, but if there is a selection area in the page you are trying to display, that information Change the display method according to

First, it is determined whether or not to use the mask function by comparing with the value of arbitrary information (VL) preset by the user. When ML satisfies the condition of VL, the selected area is displayed as a mask. For example, VL is Max If Level-1 is set, only the area marked at the time of previous opening is displayed as a mask function, and the area set before that is displayed as a mark display because it does not match the condition. . At this time, it is possible to control the color information according to the mark level. For example, all the composition values of the RGB color composition are ML / Max. By multiplying the level, the lower level area can be displayed with a lighter color. This makes it possible to highlight only selected areas that have a high mark level and are considered to be relatively important. It becomes like this.

It is also possible to emphasize not only the mark color but also the method of changing the font size. In this case, ML / Max is similarly applied to the maximum font size MFS that is arbitrarily set in advance. By treating the doubled level as the font size, the same effect can be obtained (a relatively important thing can be highlighted and displayed by enlarging it). Similarly, the same effect can be obtained by changing the thickness of the character.

  Based on the determination criteria as described above, after using the area as a mask or highlighting it as a mark, the same determination is made for all areas existing in the page, and the entire page is displayed.

When changing the condition, for example Max Even when the mask function is applied to Level-3 and later, the same operation is basically performed.

If description is added about FIG. 2, this is a case of the N-1th book opening. Marking is performed by selecting a region using a method such as mouse dragging at an important place while reading / study. The most recently assigned mark is set to the maximum mark level. Each information (mark position, mark color, mark level) is stored when the book is closed. By clicking on the mark area, you can treat it as if it was the latest mark, and toggle back and forth to the original state. The mark level is the maximum value (Max Level) is given and is decremented each time a book is opened. Along with this, it is possible to know how many times each mark was added when the book was opened, so that it is possible to perform processing such as displaying a mask for the mark of the latest X times.

  When the explanation is added to FIG. 3, when the book is opened for the Nth time, only the area of the designated level is displayed as a mask (for example, the maximum level = the area designated the previous time). The mask display will be described. When the book is opened, the mark level is decremented, the mark level is checked for each mark, and the mask display is performed when the mark level is the maximum value -1 (the previous mark). Masks are displayed for marks before / after the number of times arbitrarily designated by the user. In this case, the mask display decrements the mark level when the book is opened, checks the mark level for each mark, compares it with a mark level arbitrarily designated by the user, and displays a mask that matches the condition. In this case, areas of the same level are displayed in the same color. For marks that do not become masks, the display is changed according to the mark level information. The color is lightened according to the level (the darkest mark is displayed darker), the text is enlarged according to the level (the darkest mark is the normal size), and the text is changed according to the level. A mode of changing the thickness (displaying thicker as soon as possible) is conceivable.

4 and 5, ML is the mark level, and Max Level represents an arbitrary maximum value defined in advance. For the mark display when the VL condition is not satisfied, display is performed such that the character size is changed (the font size is larger as it is closest) or the character thickness is changed (as it is as thicker as possible) according to the ML value. Is also possible.

  In all subsequent examples, assuming that the user designates the “mask display” mode, when the user does not perform mask display, mark display based on color information is performed for all areas. In the non-display mode, no marks / masks are displayed.

  6 will be added. For the mark display when the VL condition is not satisfied, the character size is changed according to the ML value (the font size is larger as soon as possible), and the character thickness is changed (most recently). It is also possible to display “appropriately thick).

  7 and 8 are diagrams for explaining a partial operation of the content display apparatus according to the embodiment that performs mask display according to the set additional information (marked date and time). FIG. 8 is a diagram showing the case of “display”. FIGS. 9 and 10 are processing flows for performing mask display according to the set additional information [mark date and time]. FIG. 9 is a case of marking and FIG. 10 is a display. The operation will be described with reference to these drawings.

(Marking)
As an example, consider an operation when an electronic book viewer implemented as application software on a PC is used. In a situation where a book is opened and displayed on an electronic book or the like, the user can give a mark. The user sets a selection area using a mouse for an area in which the user is interested or an important word or phrase when used for learning. The operation is the same as the selection of a copy area of a generally used text editor. After selecting the area, “Copy”, “Mark”, etc. are presented as context menus, and the mark area can be set.

  If the set area is a newly set area, the area information (position information in the text, mark color information, date information) is saved for each area, and the newly set mark area is defined. Mark and display with color.

  If the set area is not a newly set area, if a click is made on the area displayed as a mark area in advance, the date of the target area is compared with today's date, If it is today's date, the stored value (OLDDT) stored in advance is set in DT. If it is not today's date, the original date is saved as OLDDT, and then today's date is set in DT. As a result, it becomes possible to control the mark level by clicking or the like, and it becomes possible to perform operations such as setting the latest date for what has been marked in the past but still seems important. For some things, you can always keep the date up to date.

  The area information thus set is stored as information in a file or the like.

(Mask)
The operation when displaying as a mask is as follows. At the same time as reading the book data, the area information created at the time of marking is read, and the mark is displayed according to the area information.
If there is no selection area in the next page, do nothing and display based on the information in the book, but if there is a selection area in the page you are trying to display, Change the display method according to the information.

  First, it is determined whether or not to use the mask function by comparing the value with an arbitrary condition (VD) preset by the user.

  When MD satisfies the condition of VD, the selected area is displayed as a mask. For example, when the VD is set to the date YYYY year MM month DD, only the region where the date information (DT) in the region information is marked on the YYYY year MM month DD is displayed as a mask function. Since the date is set as an area, it does not match the condition and is displayed as a mark display. At this time, the color information of the mark can be controlled by the date. For example, by multiplying all the composition values of the RGB color composition by (Elapsed Months + 1) / 12 times, the color becomes lighter as the date is older. If it has been more than 12 months, it can be displayed as a fixed area with the lightest color RGB * 1/12. You can only highlight and display the mark.

  It is also possible to emphasize not only the mark color but also a method such as changing the font size. In this case, the maximum font size MFS that is arbitrarily set in advance is the same (elapsed months + 1). By treating the font size multiplied by / 12 as the font size, the same effect (relatively important characters can be displayed in a highlighted manner can be displayed). Similarly, the same effect can be obtained by changing the thickness of the character.

  Based on the determination criteria as described above, after using the area as a mask or highlighting it as a mark, the same determination is made for all areas existing in the page, and the entire page is displayed.

  When the condition is changed, for example, when the mask function is applied to those after YYYY1 MM January DD1 and before YYYY2 MM2 / DD2, the same operation is basically performed.

  With respect to FIG. 7, when a description is added, mark assignment is performed by selecting a region using a method such as mouse dragging at an important place while reading / study. The area setting date is saved as additional information.

  When the explanation is added to FIG. 8, the date and time is designated, and the area set after the designated date / time / before the designated date / time / designated date / time is presented as a mask. In this case, those marked on the same date are displayed in the same color. The display of a mark that does not become a mask is also changed according to the elapsed time. Decreases the color according to the elapsed time (displays darker as the mark is closest), enlarges the character according to the elapsed time (normal size as the mark is closest), and according to the elapsed time For example, a mode in which the thickness of the character is changed (displayed as thicker as possible) is considered. By clicking on the mark area, you can treat it as if it was the latest mark, and toggle back and forth to the original state.

  If description is added about FIG. 9, it is also possible to set a period as VD conditions. For example, YYYY1 / MM1 / DD1 <= MD <= YYYY2 / MM2 / DD2. For the mark display when the VD condition is not satisfied, the character size is changed according to the YYYY / MM / DD value (the font size is larger as soon as possible), and the character thickness is changed (as is most recent as thicker). It is also possible to perform.

  FIGS. 11 and 12 are diagrams for explaining the operation of the embodiment in which the display is performed as a mask according to the number of times of marking (checking) / only the same color (≈same number of times) is marked. FIG. 12 is a diagram showing the case of “display”. FIGS. 13 and 14 are processing flows of an embodiment in which a mask is displayed according to the number of times of marking (checking) / only the same color (≈same number of times) is marked. FIG. FIG. 14 shows the case of “display”. The operation will be described with reference to these drawings.

(Marking)
As an example, consider an operation when an electronic book viewer implemented as application software on a PC is used. In a situation where a book is opened and displayed on an electronic book or the like, the user can give a mark. The user sets a selection area using a mouse for an area in which the user is interested or an important word or phrase when used for learning. The operation is the same as the selection of a copy area of a generally used text editor. After selecting the area, “Copy”, “Mark”, etc. are presented as context menus, and the mark area can be set.

  If the set area is a newly set area, the area information (position information in the text, mark color information, mark count information) is saved for each area, and the newly set mark area can be defined. Mark and display with the selected color.

  If the set area is not a newly set area, or if a click is made on an area that is displayed in advance as a mark area, the number of marks in the target area is incremented. At this time, if a predetermined maximum number of marks (Max Num) is exceeded, the number of times is set by toggling. If the original number of marks is MT, (MT + 1)% Max Num is the number of marks set. In accordance with the number of marks set in this way, a mark color is set from a separately defined table for identifying the number of marks, and the selected area is displayed in a color according to the number of marks. This makes it possible to control the number of marks by clicking and the like, and the number of marks can be arbitrarily added to an area that is desired to be masked from the next time onward or an area that is considered important. The area information thus set is stored as information in a file or the like.

(Mask)
The operation when displaying as a mask is as follows.
At the same time as reading the book data, the area information created at the time of marking is read, and the mark is displayed according to the area information. If there is no selection area in the next page, do nothing and display based on the information in the book, but if there is a selection area in the page you are trying to display, Change the display method according to the information.

  First, it is determined whether or not to use the mask function by comparing with a value of an arbitrary condition (VT) preset by the user.

  When the number of marks (MT) satisfies the condition of VT, the selected area is displayed as a mask. For example, when VT is set to the maximum value of MT, the target region is displayed as a mask function only when the mark number information (MT) of the region information is the maximum value which is a condition of VT, The number of regions other than is not displayed as a mark because it does not match the condition. At this time, the color information of the mark can be controlled by the number of marks, for example, the mark color can be displayed by using a color corresponding to a preset number of marks. By storing the color association with the color that the user thinks is important, the selection that is considered to be highly important can be marked multiple times and displayed with emphasis. .

  It is also possible to emphasize not only the mark color but also the method of changing the font size, etc. In this case, the correspondence information with the font size is similarly applied to the maximum font size MFS that is arbitrarily set in advance. By setting the font size from the above, the same effect (relatively important characters can be highlighted and displayed with emphasis) can be obtained. Similarly, the same effect can be obtained by changing the thickness of the character.

  Based on the determination criteria as described above, after using the area as a mask or highlighting it as a mark, the same determination is made for all areas existing in the page and the entire page is displayed.

  When the conditions are changed, for example, when the mask function is applied to those marked N times to M times, basically the same operation is performed.

  With respect to FIG. 11, an explanation is added. In the initial mark assignment, an important place is marked using a method such as mouse dragging while reading / study. For the second and subsequent mark assignments, it is possible to mark the same place again. Each time marking is performed, the number of marks as additional information is incremented. At the same time, the mark color is changed. Toggle the number of marks with a mark more than the specified number. It is also possible to have a UI that increments the number of marks by clicking on the mark area instead of marking. In this case, the color for displaying the region changes according to the number of clicks.

  If description is added about FIG. 12, the number of marks which is additional information will be acquired about each user mark at the time of a book display. The designated area is displayed as a mask function according to the condition of the mark count information. The condition is that only the specified number of times [≈color] is displayed as a mask.

For FIGS. 13 and 14, adding a description, Max Num represents the maximum value of the mark in which the number of times is stored + 1. It is also possible to set a section as the VT condition. For example, 3 <MT <5. For the mark display when the VT condition is not satisfied, a display such as changing the character size (the font size is larger as soon as possible) or changing the thickness of the character (as thick as possible) is displayed according to the MT value. It is also possible to do this.

  FIG. 15 is a diagram for explaining a partial operation of the content display apparatus according to the embodiment in which the mark conversion flag is directly set. FIGS. 16 and 17 are processing flows showing the operation of the embodiment in which the mark conversion flag is directly set. FIG. 16 shows the case of mark assignment, and FIG. 17 shows the case of display. The operation will be described with reference to these drawings.

(Marking)
As an example, consider an operation when an electronic book viewer implemented as application software on a PC is used. In a situation where a book is opened and displayed on an electronic book or the like, the user can give a mark. The user sets a selection area using a mouse for an area in which the user is interested or an important word or phrase when used for learning. The operation is the same as the selection of a copy area of a generally used text editor. After selecting the area, “Copy”, “Mark”, etc. are presented as context menus, and the mark area can be set.

  If the set area is a newly set area, the area information (position information in the text, mark color information, mask flag information (MF)) is saved for each area, and the newly set mark area Is displayed with a specified color.

  If the set area is not a newly set area, or if a click is made on an area previously displayed as a mark area, the mark flag of the target area is turned ON (1) / OFF (0) Switch. In accordance with the mask flag information set in this way, the selected area is displayed in a color according to the mask flag information (MF). As a result, it is possible to control the mark flag ON / OFF by clicking or the like, and it is possible to arbitrarily assign a mask to an area that is desired to be masked from the next time or an area that is considered important. Conversely, when the mask is no longer needed after the next time, the mask can be easily released. The area information thus set is stored as information in a file or the like.

(Mask)
The operation when displaying as a mask is as follows.
At the same time as reading the book data, the area information created at the time of marking is read, and the mark is displayed according to the area information.

  If there is no selection area in the display page, do nothing and display based on the information in the book, but if there is a selection area in the page you are trying to display, that information Change the display method according to At this time, when the mask flag (MF) of the area information is ON (1), the area is displayed as a mask, and when it is OFF (0), it is displayed as a mark.

  Based on the determination criteria as described above, after using the area as a mask or highlighting it as a mark, the same determination is made for all areas existing in the page, and the entire page is displayed.

  When the explanation is added with respect to FIG. 15, marking is performed by using a method such as mouse dragging for an important place while reading / study. The area to be displayed as a mask next time is clicked to add a mask area flag by clicking, and when unnecessary, the mask area flag is deleted by clicking again. When a book is displayed, it is displayed as a mask when a mask display is requested in response to a user's display change request. All the selection areas to which flags are assigned are displayed as masks.

  As described above, according to the present invention, when using the area checked by itself as a mask display for confirming the learning result, such as a test, when reading and learning, a mark is displayed as a check mechanism. Only those that need to be “confirmed” are displayed as a mask. For example, when you want to check the learning results for a place you learned a week ago, you can selectively display it as a mark. In addition, it is necessary to switch between marks and masks flexibly. In the prior example, actual product, etc., there is no method for realizing these, and there is no method for the user to easily set a mark / mask for the selected area or switch the function. According to the present invention, the mask display function and the mark display function are switched according to the conditions set by the user for the area information, so that a flexible mark / mask switching mechanism according to the setting conditions can be realized, and the user can set the mark / mask. The book can be used in various learning forms, such as being able to give a mark as a learning memo without being conscious of it, and changing it as a mask according to the mood. Further, it is not necessary to have data for masks and marks, and memory can be saved.

  It should be understood that the embodiments disclosed herein are illustrative and non-restrictive in every respect. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.

  The content display device of the present invention can use a book in various learning forms, such as being able to give a mark as a learning memo and changing it as a mask according to the mood.
