Description

  The present invention relates to an information browsing apparatus, an information browsing program, an information browsing program recording medium, and an information browsing system capable of storing, for example, the data position of an electronic book being browsed.

  In recent years, various information is provided in the form of electronic data. As an example of such electronic data, there is an electronic book obtained by digitizing a book supplied by paper. Normally, one e-book is not read at a stretch, and one e-book is read while being interrupted several times. Therefore, if there is a function (bookmark function) to resume reading from the position where it was read last time, the convenience of the reader can be improved.

  Japanese Patent Laid-Open No. 2-89176 (hereinafter referred to as “first prior art”) and Japanese Patent Laid-Open No. 2001-184354 (hereinafter referred to as “second prior art”) are inventions that provide a bookmark function.

  In the first related art, when the power of the electronic reading machine is turned off, the position of the page of the electronic book (or the position of the cursor) displayed immediately before is saved as bookmark data. And when reading the electronic book again, the bookmark data preserve | saved previously are selected and the electronic book is displayed from the position shown by the selected bookmark data.

In the second conventional technique, the start position and end position of the displayed electronic book can be specified, and the specified range can be stored as bookmark data. When the bookmark data is selected, the range indicated by the selected bookmark data is visually distinguished from other ranges. The second prior art also discloses an invention in which bookmark identification information such as a keyword or an icon is set in bookmark data.
Japanese Patent Laid-Open No. 2-89176 (published March 29, 1990) JP 2001-184354 A (published July 6, 2001)

  However, the first and second prior arts do not assume that the same electronic book is read between devices having different screen sizes or screen resolutions. Therefore, when a certain electronic book was re-read from the middle between devices with different screen sizes or screen resolutions, it was difficult to understand "how far have you read?"

  For example, as shown in FIG. 37, an electronic book is read on a device (hereinafter referred to as a first device) having a screen (small screen) 1000 having a small displayable data size such as a mobile phone during commuting and reading is interrupted. The data position of the electronic book at the time of saving is saved and continued from the data position saved on a device (hereinafter referred to as a second device) with a large screen (large screen) that can be displayed, such as a PC at home. Think if you read. In this case, the location where “there was as expected” on the small screen 1000 in the first device is “on which line exists” on the large screen 1001 in the second device. Is very difficult to understand.

  Also, the situation opposite to the above, that is, the book is read on the second device on the large screen 1001, the data position of the place where reading was interrupted is stored, and the continuation is read on the first device on the small screen 1000. Think about the case. In that case, after the reader has completely read all the characters displayed on the large screen 1001 in the second device, the reading is not always suspended. Reading a part displayed on the screen may interrupt reading. Since the prior art does not display from a reasonable position (the range that the reader has not yet read) when reading from the first device later in such a case, “how far have you read?” Is very much for the reader. Confusing.

  The reader may specify the start position and end position of the displayed electronic book manually using the second prior art, and the range may be stored as bookmark data. It takes time and effort to specify and save each one. Reading is often forced to be interrupted suddenly, so it is particularly troublesome for readers to specify a range each time reading is interrupted.

  The present invention has been made to solve the above-described problem. For example, even when the same electronic data is continuously viewed between devices having different screen sizes or screen resolutions, the information is convenient for the reader.

However, the position of the electronic data indicates the distance from the head position of the entire electronic data called “picnic” including a portion that is not displayed, such as a file position.

  In FIG. 6, the electronic data indicated by 700 is displayed, and the electronic data position (start position) corresponding to “finish” and the electronic data position (end position) corresponding to “standing” are saved as bookmark data. ing. Of course, as shown in FIG. 8, the start position and the display range may be saved as bookmark data, or the displayed data itself may be saved as bookmark data. However, in the present specification, an embodiment will be described in which the start end position and the end position are set as bookmark data, which may require the smallest storage capacity for storing bookmark data.

  The processing of FIG. 5B described here is the basis for storing bookmark data in the embodiments (C) to (E) described later, and FIG. 13 at the time of selecting bookmark data described later. The process of S202 can be realized. In other words, when creating electronic data that was read on a device with a small screen size, if the display data is to be read continuously on a device with a large screen size, and when the electronic data read on a device with a large screen size is small Independent display processing can be performed when creating display data for subsequent reading on a screen-sized device (specific creation of display data will be described later). In addition, since a display that can identify the previous display range (modified embodiment when selecting bookmark data) is possible, even if you view electronic data on a device with a different screen size, you can see how far you have read. Easy display can be realized.

(Processing when saving bookmark data-Example C)
Next, with reference to the flowchart of FIG. 5C, a further description will be given of still another embodiment of the bookmark data storage process in S107.

  In step S1001, the electronic data position (starting position) corresponding to the starting end of the displaying electronic data area (starting end of the displayed part) and the end of the displaying electronic data area (ending of the displayed part) are handled. The electronic data position (end position) is stored as bookmark data. However, the position of the electronic data indicates the distance from the head position of the entire electronic data called “picnic” including a portion that is not displayed, such as a file position.

  In S1002, it is estimated how far the reader has read the currently displayed data. Then, the electronic data position (estimated position) corresponding to the end of the estimated range is stored.

  In order to obtain the estimated position, for example, each time the reader scrolls one line, the time required for it (time required to read one line) is measured, and “number of characters displayed in one line ÷ scroll by one line” is measured. The number of characters read per unit time is calculated from “time required for”. Then, an average value of those calculation results is obtained, and it is only necessary to obtain how many characters of the displayed data have been read from “average value of the number of characters read per unit time × time for displaying data”. Also, the time required for each screen scrolling (time required to read one screen) is measured instead of the unit for scrolling one line, and “the number of characters displayed on one screen ÷ the time required for scrolling one screen” is measured. The number of characters read per unit time may be calculated from “time”. In addition, instead of dynamically calculating the “number of characters read per unit time” as described above, the device designer sets in advance the number of characters a general person reads per second (hereinafter referred to as the standard number of characters read). (For example, 2 characters / second). Further, a plurality of values for the number of characters to be read per second may be prepared so that the reader can manually select those values (for example, modes such as slow reading, normal reading, and fast reading are added).

  If the device designer sets the standard number of characters read in advance, it is not necessary to measure the “number of characters read per unit time” every time the user scrolls, so the amount of processing in S1002 is the smallest. Furthermore, when the estimated position obtained by the above method is a halfway position such as in the middle of a sentence, the position where the next phrase is located may be set as the estimated position.

  By storing the estimated position as described above, for example, when a reader reads a part of an e-book displayed on a large screen and pauses reading, the rest is read on a small screen. , It is possible to display more accurately how far the reader has read, and the continuation can be read smoothly.

  To summarize the embodiment of FIG. 5C, one bookmark data includes the start position and end position of the area displayed on the electronic data display device 5 and the estimated position that the reader may have read. It will be saved as.

  Here, as described above, the start position, the end position, and the estimated position are stored as bookmark data. However, only the estimated position may be stored as bookmark data.

(Processing when saving bookmark data-Example D)
Next, with reference to the flowchart of FIG. 5D, a detailed description will be given of still another example of the bookmark data storage process of S107.

  In step S1001, the electronic data position (start position) corresponding to the start of data in the displayed electronic data area (start of the displayed part) and the end of the displayed electronic data area (end of the displayed part) are displayed. The corresponding electronic data position (end position) is stored as bookmark data. However, the position of the electronic data indicates the distance from the head position of the entire electronic data called “picnic” including a portion that is not displayed, such as a file position.

  In S1003, it is determined whether or not there is an object serving as a mark in the electronic data area being displayed and its vicinity (the displayed portion and the range including the vicinity of the portion). The mark object is, for example, a table of contents, chapter number, paragraph position, punctuation mark, image data, animation, or a highlighted character string different from a normal format. These prominent objects are remembered by most readers, so readers can remember by saying this object, "Oh, I've read so far."

  If it is determined in S1003 that there is a mark object in the displayed electronic data area and its vicinity, the electronic data position (object position) where the object exists is saved as bookmark data in S1004.

  To summarize the embodiment of FIG. 5D, the starting position and the ending position of the area displayed on the electronic data display device 5 and the object positions in the range including the displayed data area and its vicinity are shown. It will be saved as one bookmark data.

(Processing when saving bookmark data-Example E)
The flowchart in FIG. 9 is obtained by performing all the processes of S1001 in (B), S1002 in (C), and 1003 and S1004 in (D) in FIG.

  To summarize Example E of FIG. 9, the start and end positions of the area displayed on the electronic data display device 5, the estimated position that is supposed to be read by the reader, and the electronic data display device 5. The object position in the vicinity of the area displayed in is saved as one bookmark data.

(Processing when selecting bookmark data-Example A)
Here, the processing at the time of selecting bookmark data corresponding to the bookmark data storing processing of the embodiment A will be described using the flowchart of FIG. Moreover, bookmark data is preserve | saved at the time of electronic data browsing with a 1st information browsing apparatus like FIG. 4, and the electronic data of the same content is browsed using the bookmark data after that with the 2nd information browsing apparatus. An example will be described. However, this processing can of course be realized with one information browsing device even without two information browsing devices.

  When bookmark data created by the first information browsing device is used by the second information browsing device, the external storage medium 8 is bookmarked by the external storage medium reading / writing device 4 of the first information browsing device. Write data. In the second information browsing apparatus, the bookmark data of the external storage medium 8 is read by the external storage medium reading / writing apparatus 4 of the second information browsing apparatus. The read bookmark data is stored in the storage device 3.

  The bookmark data selection process described here corresponds to the case of saving bookmark data by the process of FIG. 5A, and the processes of FIGS. 5B to 5D and FIG. Does not matter.

  In S2001, the bookmark data selection unit F4 reads the electronic data into the work area based on the end position (hereinafter referred to as a bookmark instruction end position) of the previously displayed area of the electronic data indicated by the bookmark data. And the layout data instruction | indication part F5 performs a layout instruction | indication so that it may display from the vicinity position of the bookmark instruction | indication termination position in the electronic data for browsing. Of course, it is not necessary to read or display the electronic data for browsing from the bookmark pointing end position, but it is necessary to read at least the electronic data to be displayed.

  In step S2002, the identification data instruction unit F5 issues a layout instruction so that the user can visually identify the range before and after the bookmark instruction end position in the browsing electronic data.

  FIG. 11 shows that bookmark data is stored in an information browsing apparatus with a screen (small screen) 801 having a small data size that can be displayed, and the bookmark data is stored in an information browsing apparatus with a screen (large screen) 802 having a large data size that can be displayed. The example of a display at the time of selecting is shown. In the information browsing apparatus on the large screen 802 in FIG. 11, a portion one line before the bookmark instruction end position in the electronic data for browsing is displayed, and a range before and after the bookmark instruction end position in the electronic data for browsing So that the boundary line 803 is drawn. In addition, in order to identify each range, the font color, font typeface, font size, or background color on which these fonts are displayed may be changed in the vicinity of the boundary line. Further, instead of the boundary line as shown in Fig. 11, the character corresponding to the end position of the bookmark may be simply divided by the symbol "" "804 as shown in Fig. 12. In this case, the processing amount for drawing is the smallest.

  In S2003, the display data creation unit F6 creates display data for displaying the read electronic data based on the layout instruction.

  In S2004, the display data created in S2003 is output to the display device 5.

  Unlike the case shown in FIG. 37, in the case of FIG. 11, the bookmark data is stored in the information browsing device on the small screen 801 and the bookmark data is selected on the information browsing device on the large screen 802. By storing the electronic data position (terminal position) corresponding to the end of the electronic data area displayed when the bookmark data is stored as bookmark data, it is easy to see how far the information is displayed on the information browsing device of the small screen 801. It is easy for readers to understand how far they have read or where they have read.

FIG. 13 shows that bookmark data is stored in an information browsing apparatus having a large screen (810) with a large data size that can be displayed, and the bookmark data is stored in an information browsing apparatus with a small screen (small screen) 811 that can be displayed. The example of a display at the time of selecting is shown. In FIG. 13, when the screen is scrolled up, a range 812 before the bookmark instruction end position is displayed.
In FIG. 13, a boundary line is drawn so that a range before and after the bookmark instruction end position in the electronic data for browsing can be identified visually. It should be noted that the font color, font typeface, or font size of each range may be changed so that they can be identified. Alternatively, the character corresponding to the end position of the bookmark may be separated by the symbol “”. ”In this case, the processing amount required for drawing is the smallest.

  By performing the display as shown in FIG. 13, it is easy for the reader to understand “how far the user has read” even when the information browsing device on the large screen 810 was viewed last time.

(Processing at the time of selecting bookmark data-processing overview of Examples B to E)
Here, the outline of the process at the time of bookmark data selection corresponding to the bookmark data storing process of the above-described Examples B to E will be described using the flowchart of FIG. Further, when bookmark data is stored when browsing electronic data in a certain information browsing apparatus as shown in FIG. 4, and then electronic data having the same content is browsed using the bookmark data in another information browsing apparatus. An example is given. However, this processing can be realized by one information browsing device, of course, without two information browsing devices. For example, the present invention can be applied to an information browsing apparatus that can change the size of electronic data that can be displayed.

  In S <b> 201, the bookmark data selection unit F <b> 4 expands the content of the bookmark data selected by the reader using the input device 2 in the work area of the storage device 3.

  In S202, the size of the display area (the size of the display data indicated by the bookmark data) necessary for the identification data instruction unit F5 to display the range from the start position to the end position of the bookmark data of the electronic data is determined. It is determined whether or not the display area size of the electronic data currently being displayed (the size of the display data currently being displayed) is smaller. This determination is performed by comparing the area of the display area necessary for displaying electronic data from the start position to the end position of bookmark data in a logical unit that is a coordinate unit independent of the device. If it is determined that the value is smaller, the process proceeds to S203. If it is determined that this is not the case, the process proceeds to S204. Instead of comparing the size of the display area necessary for displaying electronic data, the size of the amount of electronic data required for display may be simply compared.

  In S203, identification data is created that makes it easy to see how far the user has viewed the previous display data when the size of the display data currently displayed is larger than the size of the display data displayed last time. Specific processing in S203 will be described later.

  The situation of S204 is processing in the situation opposite to that of S203. That is, this is a process when the size of the display data currently displayed is smaller than the size of the display data displayed previously. Specific processing of S204 will be described later.

  The processing of S203 and S204 will be described below in correspondence with each of bookmark data storage processing in Examples B to E.

  If only the estimated position is saved as bookmark data in the bookmark data saving process of the embodiment C, the branch of S202 cannot be performed. In that case, only the processing of S201 and S204 may be performed.

(Processing when selecting bookmark data-Example B)
Here, the embodiments of S203 and S204 will be described using the flowcharts of FIGS. Note that the bookmark data selection process described here corresponds to the case of saving bookmark data by the process of FIG. 5B, and FIGS. 5A, 5C, and 5D. As well as the processing of FIG.

  First, the process of S203 corresponding to FIG. 5B will be described in detail with reference to FIG.

  In S2051, the electronic data is read into the work area based on the start position of the electronic data indicated by the bookmark data (hereinafter referred to as a bookmark instruction start position). Of course, it is not necessary to read exactly from the bookmark instruction start position, and electronic data may be read from positions before and after the bookmark instruction start position. However, the layout instruction is given so that the display starts from the electronic data in the vicinity of the bookmark instruction start position or the bookmark instruction end position.

  In step S2052, the identification data instruction unit F5 displays the electronic data range indicated by the bookmark data in the browsing electronic data, that is, the data range from the bookmark instruction start position to the bookmark instruction end position (hereinafter referred to as a bookmark instruction range). And other data ranges are instructed so that the user can visually identify them.

  In S2053, the display data creation unit F6 creates display data for displaying the read electronic data based on the layout instruction.

In S2054, the display data created in S2053 is output to the display device 5.
FIG. 16 shows that bookmark data is stored in an information browsing device having a small screen (small screen) 901 that can be displayed, and the bookmark data is stored in an information browsing device having a large screen (large screen) 902 that can be displayed. The example of a display at the time of selecting is shown. In the information browsing apparatus on the large screen 902 in FIG. 16, the bookmark instruction start position in the browsing electronic data is displayed, and the font of the portion displayed on the information browsing apparatus on the small screen 901 is bold. The bookmark instruction range and other ranges can be visually identified for the user. Further, in the information browsing apparatus on the large screen 902, the font color, font typeface, font size, or background color on which these fonts are displayed may be changed in the portion displayed on the information browsing apparatus on the small screen 901. . Furthermore, it is also possible to display only the boundary line between the bookmark instruction range and the range not.

  Unlike the case of FIG. 37, in the case of FIG. 16, the bookmark data is stored in the information browsing device on the small screen 901, and the bookmark data is selected on the information browsing device on the large screen 902. By saving the start position of the electronic data area being displayed and the end position of the electronic data area being displayed as bookmark data when the bookmark data is saved, the portion displayed on the information browsing device of the small screen 901 can be displayed in an easily understandable manner. Therefore, the reader can clearly see how far he has read or where he has read.

  Also, FIG. 17 shows that bookmark data is stored in the information browsing apparatus on the screen (small screen) 901 with a small data size that can be displayed, and the bookmark instruction is displayed on the information browsing apparatus on the screen (large screen) 903 with a large data size that can be displayed. It is an example of a display at the time of displaying from the electronic data of one line before the end position. When the reader scrolls up, the user can visually identify the bookmark instruction range and the other ranges in the same manner as in FIG. In the case of FIG. 17, unlike the case of FIG. 16, the previous display range is hardly displayed (since only a part is displayed), the reader does not need to scroll to skip the previous display range, and is easy to use. Is good.

  Next, the process of S204 corresponding to FIG. 5B will be described in detail using the flowchart of FIG.

  In step S2101, electronic data is read into the work area based on the bookmark instruction start position. Of course, it is not necessary to read exactly from the bookmark instruction start position, and electronic data may be read from positions before and after the bookmark instruction start position. However, the layout instruction is given so that the display starts from the electronic data in the vicinity of the bookmark instruction start position or the bookmark instruction end position.

  In S2102, the electronic data up to the bookmark instruction end position is divided for each phrase, and a list indicating the divided data is created. In addition, the division start position where the division of electronic data is started may be anywhere, but for example, it may be started from the beginning of the electronic data.

  In S2103, the identification data instruction unit F5 changes display data such that the bookmark instruction range and other ranges in the electronic data for browsing are easily identified visually by the user, for example, the background color of each range is changed. A layout instruction for creating display data is given.

  In S2104, the display data creation unit F6 creates display data for displaying a list of divided data and electronic data based on the layout instruction.

In S2105, the display data created in S2104 is output to the display device 5.
FIG. 19 shows that bookmark data is stored in an information browsing device with a large screen (large screen) 910 that can be displayed, and the bookmark data is stored in an information browsing device with a small screen (small screen) 911 that can be displayed. The example of a display at the time of selecting is shown. It can be seen that the electronic data before the bookmark indication end position is divided for each phrase and the list is displayed on the small screen 911. Then, when the reader uses the input device 2 to select an element in the list (the list element “Today is 5:00 AM…” is selected in the information browsing apparatus on the small screen 911 in FIG. 19), the list Display in detail from the electronic data position corresponding to the element. Note that it is not necessary to divide into each punctuation point, and it may be divided into symbols such as line feed codes. Further, tags representing division points such as XML may be embedded in electronic data in advance, and the electronic data may be divided for each tag.

  In addition, although not shown in FIG. 19, when the screen is scrolled, the background color of the bookmark indication range and the other range changes, and each range can be easily identified visually by the user. Yes. It should be noted that the font color, font typeface, or font size of each range may be changed so that they can be identified. Further, it is also possible to display only the boundary line between the range of electronic data indicated by the bookmark data and the range not.

  By displaying such that the bookmark instruction range and the range outside the bookmark range can be easily visually identified by the user, even if the information was viewed on the information browsing device of the large screen 910 last time, The user clearly knows "where he was reading." Normally, the electronic data range displayed on the information browsing device on the large screen 910 cannot be displayed on one screen on the information browsing device on the small screen 911. Although it takes time and effort to scroll, the reader can easily grasp the contents by dividing the electronic data and displaying the list.

  FIG. 20 shows a bookmark instruction termination position stored in the information browsing apparatus of a screen (small screen) 912 having a small data size that can be displayed by storing bookmark data in the information browsing apparatus of a large screen (large screen) 910 that can be displayed. It is an example of a display at the time of displaying from the electronic data of 1 line before. When the reader scrolls up, the bookmark indicating range can be identified in the same manner as in FIG. In the case of FIG. 20, unlike the case of FIG. 19, the previous display range is hardly displayed, so that the reader does not need to scroll to skip the previous display range, which is convenient.

(Processing when selecting bookmark data-Example C)
The embodiment of S204 will be described with reference to the flowcharts of FIGS. Note that the bookmark data selection process described here corresponds to the case where bookmark data is stored by the process of FIG. 5C, and FIGS. 5A, 5B, and 5D. As well as the processing of FIG. Further, the processing of S203 corresponding to (C) of FIG. 5 is the same as the processing of FIG.

  First, the first embodiment of the process of S204 corresponding to FIG. 5C will be described with reference to FIG.

  In S2110, electronic data is read into the work area based on the bookmark instruction start position. Of course, it is not necessary to read exactly from the bookmark instruction start position, and electronic data may be read from positions before and after the bookmark instruction start position. When only the estimated position is stored as bookmark data in the bookmark data storage process, it is sufficient to read from the estimated position.

  In step S2111, the identification data instruction unit F5 issues a layout instruction so that display data is displayed from the estimated position indicated by bookmark data (hereinafter referred to as a bookmark instruction estimated position). In addition, since the bookmark instruction estimated position does not necessarily match the position actually read by the reader, it is not necessary to display it exactly from the bookmark instruction estimated position. For example, even if the bookmark instruction estimated position is displayed from around several bytes of the bookmark instruction estimated position. Good.

  In S2112, the display data creation unit F6 creates display data for displaying the read electronic data based on the layout instruction.

  In S2113, the display data created in S2112 is output to the display device 5.

  In FIG. 22, bookmark data is stored in the information browsing apparatus of a screen (large screen) 920 having a large displayable data size, and the bookmark data is stored in the information browsing apparatus of a screen (small screen) 921 having a small displayable data size. The example of a display at the time of selecting is shown. In FIG. 22, it is assumed that the reader has read the range indicated by the broken line 922, the estimated position is stored as bookmark data, and is displayed from the estimated position when bookmark data is selected on the small screen 921. I understand that.

  In this way, since the display is based on the position estimated by the reader, it is possible to view the continuation from near the reader's desired position. You don't have to scroll many times to find a boundary with a sentence that hasn't been done. Although not shown, a boundary line may be drawn so that a range before and after the estimated position can be identified as in FIG. By doing so, the reader can more clearly grasp the boundary between the text that has been read and the text that has not been read.

  Next, a second embodiment of the process of S204 corresponding to FIG. 5C will be described with reference to FIG.

  In S2120, electronic data is read into the work area based on the bookmark instruction start position. Of course, it is not necessary to read exactly from the bookmark instruction start position, and electronic data may be read from positions before and after the bookmark instruction start position.

  Then, the layout instruction may be performed so that electronic data is displayed based on any one of the bookmark instruction start position, the bookmark instruction end position, or the bookmark instruction estimated position. It is good to display electronic data from. By doing so, even if the user does not use the input device 2 to scroll the screen, there is a boundary between the range presumed to be read and the range that was previously displayed but presumed to be unread. I understand clearly.

  In S2121, the identification data instruction unit F5 determines the range from the bookmark instruction start position to the bookmark instruction estimated position (the area estimated to have been read), the range from the bookmark instruction estimated position to the bookmark instruction end position (displayed previously). The layout is instructed so that a range other than the above can be identified.

  In S2122, the display data creation unit F6 creates display data for displaying the electronic data based on the layout instruction.

  In S2123, the display data created in S2122 is output to the display device 5.

  In FIG. 24, bookmark data is stored in an information browsing apparatus having a large screen (large screen) 920 that can be displayed, and the bookmark data is stored in an information browsing apparatus having a small data (screen) 921 that can be displayed. This is an example when selected. In FIG. 24, it is estimated that the reader has read the range indicated by the broken line 922, and the estimated position is stored as bookmark data. When the bookmark data is selected by the information browsing device on the small screen 921, the range indicated by 925 (the range estimated to have been read) and the range indicated by 926 (the previous display) By using different background colors (colors are not shown) for the range indicated by 924 (the range other than 925 and 926) and the range indicated by 924, each can be identified. However, the range of 924 and 925 is actually displayed on the screen 921 when scrolling. Each of the ranges may be identified by changing the font color, font typeface or font size. Further, it is also possible to display only the boundary line between the bookmark instruction range and the range not.

  As shown above, the range that is estimated to have been read, the range that was displayed the previous time but that is estimated to be unread, and the other range are displayed so that the reader can distinguish them. Or where to start reading.

  FIG. 25 is a display example when electronic data is displayed slightly before the estimated position of bookmark data in the same situation as FIG. Unlike FIG. 24, FIG. 25 clearly shows the boundary between the range estimated to be read and the range estimated to be unread but previously displayed without scrolling.

  Finally, a third embodiment of the process of S204 corresponding to FIG. 5C will be described with reference to FIG.

  In S2130, electronic data is read into the work area based on the bookmark instruction start position. Of course, it is not necessary to read exactly from the bookmark instruction start position, and electronic data may be read from positions before and after the bookmark instruction start position.

  The layout instruction may be performed so that electronic data is displayed based on any one of the bookmark instruction start position, the bookmark instruction end position, or the bookmark instruction estimated position. When the electronic data is displayed, the boundary between the presumed read range and the presumed unread read range can be clearly seen without scrolling.

  In S2131, the electronic data up to the bookmark instruction end position is divided for each phrase, and a list indicating the divided data is created. In addition, the division start position where the division of electronic data is started may be anywhere, but for example, it may be started from the beginning of the electronic data. Moreover, it is not necessary to divide into each punctuation point, and may divide into each symbol such as a line feed code. Further, tags representing division points such as XML may be embedded in electronic data in advance, and the electronic data may be divided for each tag.

  In S2132, the identification data instructing unit F5 has a range from the bookmark instruction start position to the bookmark instruction estimated position (a range estimated to have been read) in the browsing electronic data, a range from the bookmark instruction estimated position to the bookmark instruction end position. The layout is instructed so that the user can visually identify the range other than the above (the range that was previously displayed but is estimated to be unread). However, unlike the embodiment of FIG. 23, in FIG. 26, a list of divided data is provided before the estimated position.

  In S2133, the display data creation unit F6 creates display data for displaying a list of divided data and electronic data based on the layout instruction.

In S2134, the display data created in S2133 is output to the display device 5.
In FIG. 27, it is estimated that the range 922 (the range surrounded by a broken line) has been read by the information browsing apparatus 920 having a large data size that can be displayed by the reader (large screen) 920, and the estimated position is used as bookmark data. This is an example when the bookmark data is selected by the information browsing apparatus of the screen (small screen) 921 having a small data size that can be stored and displayed. When the bookmark data is selected by the information browsing device on the small screen 921, the range indicated by 928 (the range estimated to have been read) and the range indicated by 929 (the previously displayed but unread) By using different background colors (colors are not shown) for the range (presumed to be present) and the range indicated by 927 (the range other than 928 and 929), each can be identified. However, the ranges of 927, 928 and 930 are actually displayed on the screen 921 when scrolling. Here, a list of divided data is displayed in the data range up to the bookmark instruction estimated position (range of 927 and 928). When the reader uses the input device 2 and selects an element in the list, details are displayed from the electronic data position corresponding to the list element. Each of the ranges may be identified by changing the font color, font typeface or font size. Further, it is also possible to display only the boundary line between the bookmark data instruction range and the range not.

  The reader will be able to distinguish between the range that has been read and the range that was previously displayed but is estimated to be unread, and the other range. Is easier to understand.

  Furthermore, when the estimated position estimated by the bookmark data storage unit F3 is incorrect (the estimated position is different from the position read by the reader), the electronic data above the estimated position is divided and displayed as a list. The reader can easily understand the contents without having to scroll again, so it becomes easier to understand where to read.

(Processing when Bookmark Data is Selected—Example D)
Here, the embodiments of S203 and S204 will be described using the flowcharts of FIGS. The bookmark data selection process described here corresponds to the case where bookmark data is stored by the process of FIG. 5D, and FIGS. 5A to 5C and FIG. It is not related to the processing.

  First, the processing of S203 corresponding to (D) of FIG. 5 will be described in detail with reference to FIG.

In S2140, it is determined whether or not the bookmark data includes an object (object position) as a mark. If an object to be a mark is included, electronic data is read into the work area so as to include at least the bookmark indication range (the range from the bookmark indication start position to the bookmark indication end position) as the object position in S2141. . If the mark object is not included, electronic data is read into the work area from the bookmark instruction start position in S2142. Of course, it is not necessary to read exactly from the bookmark instruction start position, and the electronic data may be read from the position before the bookmark instruction start position as cache data.
In S2143, the identification data instruction unit F5 allows the user to visually identify the bookmark instruction range in the browsing electronic data, that is, the data range from the bookmark instruction start position to the bookmark instruction end position and other data ranges. Instruct layout.

  In S2144, it is determined whether or not the data in the bookmark indication range can be displayed on the screen when electronic data is displayed from the object position. This is a determination for displaying at least the bookmark instruction range. If it is determined that the electronic data in the bookmark instruction range can be displayed on the screen, a layout instruction for displaying display data is performed from the object position of the bookmark data in S2145. If it is determined that this is not the case, a layout instruction for displaying display data is performed from the bookmark instruction start position in S2146.

  In S2147, the display data creation unit F6 creates display data for displaying electronic data based on the layout instruction.

In S2148, the display data created in S2147 is output to the display device 5.
In FIG. 29, bookmark data is stored in an information browsing apparatus with a screen (small screen) 941 having a small displayable data size, and the bookmark data is stored with an information browsing apparatus in a screen (large screen) 942 having a large displayable data size. The example of a display at the time of selecting is shown. In FIG. 29, since there is a chapter number as an object in the vicinity 940 of the electronic data displayed on the information browsing apparatus on the small screen 941, the position of the chapter number (object position) is saved as bookmark data. When the bookmark data is selected by the information browsing apparatus 942 on the large screen, the chapter number is displayed so that it can be seen. In this way, most readers remember prominent objects, such as chapter numbers, so readers can remember things like “Oh, I ’ve read so far” by looking at this object. . Furthermore, by displaying the bookmark indication range so that it can be easily distinguished from the outside of the range, the reader can clearly understand “how far” or “where”.

  Next, the process of S204 corresponding to FIG. 5D will be described in detail with reference to FIG.

  In S2160, it is determined whether or not there is an object (object position) serving as a mark in the electronic data within the bookmark instruction range (the range from the bookmark instruction start position to the bookmark instruction end position).

  If it is determined in S2160 that there is a mark object within the bookmark instruction range, electronic data is read from the object position into the work area in S2161, and the process proceeds to S2163. Of course, it is not necessary to read exactly from the object position, and the electronic data may be read from a position before the object position as cache data.

  In S2163, a layout instruction is issued so that electronic data is displayed from the object position.

  If it is determined in S2160 that there is no mark mark within the bookmark instruction range, electronic data is read into the work area from the bookmark instruction start position in S2162, and the process proceeds to S2164. Of course, it is not necessary to read exactly from the bookmark instruction start position, and the electronic data may be read from the position before the bookmark instruction start position as cache data.

  In S2164, a layout instruction is issued so that electronic data is displayed from the bookmark instruction start position.

  In S2165, the electronic data up to the bookmark instruction end position is divided for each phrase, and a list indicating the divided data is created. Note that it is not necessary to divide every punctuation point, and for example, division may be made for each symbol such as a line feed code. Further, tags representing division points such as XML may be embedded in electronic data in advance, and the electronic data may be divided for each tag.

  In S2166, the identification data instruction unit F5 displays the range of electronic data indicated by the bookmark data in the browsing electronic data, that is, the data range from the start position to the end position of the bookmark data and other data ranges. Instruct the layout so that can be identified visually.

  In S2167, the display data creation unit F6 creates display data for displaying a list of divided data and electronic data based on the layout instruction.

In S2168, the display data created in S2167 is output to the display device 5.
When reading electronic data that has been browsed on a large-screen information browsing device from a small screen information browsing device, it is displayed from the object that was displayed on the large-screen information browsing device. By looking at this object, you can recall things like "Oh, I read so far."

Here, a process when selecting bookmark data when bookmark data is stored by the process (E) of FIG. 9 will be described. Note that this does not relate to the processing from (A) to (D) in FIG.

  The process of S203 can use the process of FIG. 28 described above. In addition, the process of S204 described above can be used for the process of S204. Since the processes in S203 and S204 are the same as those described above, a description thereof will be omitted.

  For example, bookmark data is stored by the process of FIG. 9 in an information browsing apparatus with a small displayable data size (small screen), and the bookmark data is displayed in an information browsing apparatus with a large displayable data size (large screen). When is selected, the processing of FIG. 28 can be performed. Further, when bookmark data is stored by the process of FIG. 9 in the information browsing apparatus on the large screen and the bookmark data is selected by the information browsing apparatus on the small screen, either of FIG. 21, FIG. 23 or FIG. Can be processed. Therefore, a better process can be selected and used in each of Example C and Example D. In other words, the process of S204 of Example C that achieves a better effect than the process of S204 of Example D is adopted, and the process of S203 of Example D that provides a better effect than the process of S203 of Example C is adopted. Can be adopted.

(Processing at the time of selecting bookmark data-modified examples of Examples B to E)
In the embodiment described above, the size of the display area (the size of the display data indicated by the bookmark data) necessary for displaying the range indicated by the bookmark data of the electronic data is determined in S202 of FIG. It is determined whether or not it is smaller than the size of the display area of the electronic data currently displayed (the size of the display data currently being displayed), and different processing is performed in each case. However, the processing of S2051 to S2054 (same as in FIG. 15) is performed without performing the determination of S202 as shown in FIG. 31, and the electronic data range indicated by the bookmark data, that is, the start position of the bookmark data of the electronic data The data range from to the end position may be displayed so that it can be distinguished from other data ranges. In that case, since the display that can identify the previous display range is possible, even if you browse the electronic data with an information browsing device with a different screen size, it is possible to realize an easy-to-understand display of how far you have read Become.
