Description

The present invention displays texts such as e-mails, website contents, and e-books on mobile terminals such as mobile phones, PHS, and PDAs, and personal computers (collectively referred to herein as “terminals”). The present invention relates to a scroll control system that automatically controls the scrolling speed based on the number of dots used to display characters in a sentence.

  When an e-mail or website is displayed on a terminal, the sentence may be long. In such a case, since the entire sentence cannot be displayed on one screen, the terminal user performs a scroll operation to sequentially display.

  However, since the scroll operation becomes complicated when the sentence becomes long, an invention for performing scroll control as disclosed in the following patent document is disclosed.

JP 2003-108487 A JP 2000-311045 A Japanese Patent Laid-Open No. 10-228472 JP 2000-172245 A JP 2001-147918 A JP 2001-202077 A

  By using the invention described in Patent Document 1, it is possible to determine the scroll speed according to the total number of characters in the sentence and to perform automatic scroll control. However, in the present invention, the font size and scroll speed are determined simply by the total number of characters in the sentence, so it is not always possible to see the sentence with high visibility for the user of the terminal.

  In particular, the visibility of a sentence becomes difficult to read if there are many margins of displayed characters even if the sentences have the same total number of characters, and it becomes easier to read if there are many margins. FIG. 3 schematically shows this. FIGS. 3A and 3B are sentences with the same total number of characters, but (a) has less margins and (b) has more margins. That is, it can be seen that (a) is more difficult to read than (b) even for sentences with the same number of characters. Therefore, in the case of determination based on the total number of characters, visibility (difficulty in reading) is not always improved.

  Also, if the text is difficult to read, the visibility of the user of the terminal cannot be improved unless scrolling is performed at a slower speed than the easy-to-read text. However, as in the invention described in Patent Document 1, when the scroll speed is determined only by the total number of characters, as described above, if the same total number of characters is used, a sentence that is difficult to read (a sentence with a small margin), a sentence that is easy to read (a lot of a margin) In any case, there is a problem that scroll control is performed at the same scroll speed.

  Further, according to the invention described in Patent Document 2, the visibility when scrolling a sentence can be improved by changing the shift interval when scrolling characters in the sentence. However, even if this invention is used, since it only controls the shift interval during scroll display, it is possible to perform scroll control in consideration of the readability and difficulty of reading of the original text. Absent. In other words, if the text is difficult to read even without scrolling, when scrolling the text, it is necessary to control the scrolling in consideration of the difficulty of reading (such as slowing down the scroll speed or reducing the scroll amount). However, such processing cannot be performed. Therefore, it is impossible to control scrolling due to the readability of the text itself and the difficulty of reading.

  Furthermore, in Patent Document 3, display control such as enlarged display of input characters can be performed by using the line density for each character in a sentence. However, it is difficult to appropriately enlarge and display text characters in e-mails and websites received by mobile terminals and personal computers. This is because the invention described in Patent Document 3 is an invention for enlarging and displaying misleading characters in order to accurately input characters to be input, and is intended to control scrolling of text displayed on a terminal, which is the object of the present application. This is because it does not take into account the difficulty of reading the text and ease of reading.

  In particular, in the above invention, the system must possess data called the line density at the portion where the line is the densest among the characters as a display auxiliary information dictionary for each character, and the system needs a storage capacity. It becomes. It is not realistic to provide such a display auxiliary information dictionary for all characters. Furthermore, since each character is judged, the enlarged and non-enlarged characters are displayed together in one sentence, which makes the sentence as a whole difficult to read. There is.

  In addition to the scroll control, there are also inventions described in Patent Documents 4 to 6 in order to improve the visibility of sentences and characters.

  In the invention described in Patent Document 4, the display is performed with the size of characters that the entire sentence can be displayed based on the information amount (number of characters) of the entire sentence displayed on the portable information terminal or the communication terminal, that is, the total number of characters in the sentence. A system that performs display control using a font having a size that is easy to read or read is disclosed. However, since the present invention also performs display processing based on the total number of characters in the sentence, as in the invention of Patent Document 1, there is a problem similar to the above.

  Further, the invention described in Patent Document 5 discloses a system that determines the number of characters for each sentence in a sentence and performs display control of the character size. This invention also has the same problems as Patent Document 1 and Patent Document 4, and the size of characters displayed for each sentence may change in the entire sentence, which makes it extremely difficult to read. Absent. In particular, if the size of the character changes for each sentence, if the scroll control is performed there, the visibility of the user of the terminal is significantly deteriorated.

  Further, the invention described in Patent Document 6 discloses an invention that improves the visibility by controlling the display of the character size according to the number of strokes of the character included in the sentence. Certainly, by using the number of strokes as a judgment material for display control, it may be possible to improve the visibility rather than just judging by the number of characters. In this case, the number of strokes for each character is provided in the terminal as information. Must be. Therefore, in order to store information on the number of strokes of each character, a corresponding storage area must be provided, and there is a problem that it is difficult to use in a portable terminal having a small storage capacity.

  Therefore, in view of the above-mentioned problems, the present inventor uses the number of dots used for displaying the text of the text on the screen when performing scroll display of the text on a terminal, particularly a mobile terminal. Invented a scroll control system that can control scrolling at a scrolling speed and scrolling amount suitable for readability and reading difficulty.

  The invention of claim 1 is a scroll control system that performs scroll control of a sentence displayed on a terminal, the scroll control system including a sentence reading unit that reads a sentence to be processed, and which character in the read sentence A reference total dot number calculation unit that calculates a reference total dot number by counting whether or not only a character is included, and a dot count unit that counts the number of dots actually used to display characters in the sentence And the ratio of dots used to display text characters based on the reference total dot number calculated by the reference total dot number calculation unit and the dot number counted by the dot count unit.

A determination unit that determines whether to change scroll control of the sentence using a ratio, and a change in scroll control in the determination unit When it is determined to do, during the read text scrolling to display in the display device of the terminal, a scroll control system having a scroll control unit that performs scroll control the determination in the determination unit.

  According to the present invention, as in the case of the above-described invention, the scroll control of the text displayed on the terminal can be automatically adjusted according to the readability and difficulty of reading the text. You can see the text at In the above-described invention, the display device is configured to change the scroll control after the text is displayed once. However, in the present invention, the screen of the terminal is changed after the scroll control is changed. You can display a sentence. This reduces the user's uncomfortable feeling.

  4. The reference total dot number calculation unit according to claim 3, wherein the reference total dot number calculation unit calculates the reference total dot number by multiplying the counted number of characters by an average area size necessary for displaying one character. This is a scroll control system.

  Since the average size of the area required to display one character is known in advance, the size necessary for the entire sentence (number of dots) is calculated by multiplying the size by the number of letters in the sentence. I can do it.

  The invention according to claim 4, wherein the determination unit is configured to display a ratio of dots used to display characters in a sentence based on the reference total dot number and the dot number counted by the dot count unit, or It is determined whether to change the scroll control of the sentence by calculating a ratio of dots used for displaying characters in the sentence and comparing the ratio with a predetermined reference value. A scroll control system.

  As in the present invention, the percentage of used (used) dots is high when there are many dots used (used) as characters. That is, the size of characters is thin, or many characters with a large number of strokes are displayed. The inventor's research has found that such text is difficult to read when viewed on a terminal. Therefore, by comparing the ratio with a predetermined reference value and changing the scroll control, it is possible to perform scrolling in consideration of the readability of the text.

  6. The scroll control system according to claim 5, wherein the change of the scroll control of the sentence includes either a change of a scroll speed or a change of a scroll amount.

  Although there are several scroll controls, the processing as in the present invention is a typical example, and these may be used.

  The scroll control system according to claim 6, wherein the sentence includes at least one of electronic mail, website content, and electronic books.

  A typical example of a sentence to be processed by a terminal is the one according to the present invention.

  The invention according to claim 7 is a sentence reading unit for reading a sentence to be processed, and a reference total dot for calculating a reference total dot number by counting how many characters are included in the read sentence. A number calculation unit, a dot count unit that counts the number of dots actually used to display characters in the sentence, a reference total dot number calculated by the reference total dot number calculation unit, and a dot count unit Based on the counted number of dots, a determination unit that calculates a ratio of dots used to display text characters and determines whether to change scroll control of the text using the ratio, When the determination unit determines that the scroll control is to be changed, the determination is performed when the read sentence displayed on the display device of the terminal is scrolled. Scroll control processing unit for performing scroll control that determines the parts, a character display control program for functioning as a.

  The invention according to claim 8 is a sentence reading unit for reading a sentence to be processed, and a reference total dot for calculating a reference total dot number by counting how many characters are included in the read sentence. A number calculation unit, a dot count unit that counts the number of dots actually used to display characters in the sentence, a reference total dot number calculated by the reference total dot number calculation unit, and a count by the dot count unit A determination unit that calculates a ratio of dots used to display text characters based on the number of dots and determines whether to change scroll control of the text using the ratio; If it is determined that the scroll control is to be changed in step S1, the determination unit receives the scrolling of the read sentence displayed on the display device of the terminal. Scroll control processing unit that performs scroll control that determines Te, a character display control program for functioning as a.

  Each above-mentioned invention can also be comprised as a program like this invention. The above-described system is executed by causing the terminal to read the program and perform processing.

  By using the present invention, it is possible to control scrolling at a scrolling speed and a scrolling amount suitable for readability of text displayed on a terminal and difficulty in reading.

Further, since the number of characters is not determined as in the prior art, more accurate text scroll control can be performed. In other words, even if the text has the same total number of characters, if the number of dots used for character display is small, the text is scrolled at the normal scrolling speed and scroll amount, while if the number of dots used for character display is large. Sentences are scrolled at a slower speed and a smaller scroll amount than usual. Furthermore, since processing is not performed in units of characters, characters that are enlarged in one sentence and characters that are not enlarged are not mixed. In addition, since the determination is not performed based on the number of strokes of characters, it is not necessary to store information on the number of strokes of each character, and the device can function effectively even in a portable terminal having a small storage area.

  An example of a conceptual diagram of the system configuration of the present invention is shown in FIG. The scroll control system 1 of the present invention is used when a sentence such as an electronic mail, a website, or an electronic book is displayed on a terminal. The scroll control system 1 is realized on a terminal that controls the processing of the present invention. This terminal has at least an arithmetic device such as a CPU for executing arithmetic processing of a program, a storage device such as a RAM or a hard disk for storing information, and a display device such as a display. Each function (each unit) realized on the terminal is executed when a unit (program, module, etc.) for executing the process is read by the arithmetic unit. When each function uses the information stored in the storage device in the processing, each function reads the corresponding information from the storage device, and uses the read information for processing in the arithmetic device as appropriate. The terminal may include a communication device that transmits and receives processing results of the arithmetic device and information stored in the storage device via a network such as the Internet or a LAN, and an input device such as a keyboard, a mouse, or a numeric keypad.

  Each function (each unit) in the present invention is only logically distinguished from each other, and may be physically or effectively the same area. Each function can be processed by one or a plurality of programs, modules, devices, or the like.

  The scroll control system 1 includes a text reading unit 2, a reference total dot number calculation unit 3, a dot count unit 4, a determination unit 5, and a scroll control processing unit 6.

  The text reading unit 2 reads e-mail and website text displayed on the display device of the terminal. The sentence read here becomes the processing target of the present invention. In addition, a sentence means what consists of one or several sentences. A sentence means one or a plurality of letters, numbers, symbols, marks (pictograms, etc.) (collectively referred to as “characters” in this specification), and the like. The text to be processed by the text reading unit 2 may be an entire text composed of a plurality of texts, or a text in a range specified by the user with an input device or the like in the entire text or a predetermined text. A sentence unit (for example, every paragraph, every article, etc.) may be a sentence to be processed. Alternatively, each sentence displayed on the terminal display device may be read and processed.

The reference total dot number calculation unit 3 counts how many characters are included in the text read by the text reading unit 2. Then, when displaying characters on the terminal, the size (number of dots) of an average area necessary to display one character (for example, vertical 16) depending on the character font and font size preset on the terminal. (Dots, horizontal 16 dots) are known (the average area size per character is set in advance by the reference total dot number calculation unit 3 and stored). By multiplying the size by the counted number of characters, the average size (average number of dots) of the area necessary for displaying the sentence is calculated. For example, if the text is 50 characters and the average size of the area required to display one character is 16 dots long and 16 dots wide,
(Equation 1)
The reference total dot number calculation unit 3 calculates that 50 × 16 × 16 = 12,800 dots are required. The average area size necessary for displaying the entire sentence, calculated by the reference total dot number calculation unit 3, is referred to as a reference total dot number.

  The dot count unit 4 counts the number of dots used for actually displaying characters in the text displayed on the display device of the terminal. When a character is displayed in black on the terminal, in order to display one character, dots (pixels) included in a rectangular area for displaying one character are displayed in black, and the others are, for example, white And is done by Therefore, the number of black dots in the entire sentence is calculated by counting the dots displayed as black for each character. The number of dots used (used) for character display can be determined from hardware or software that executes processing related to control of the display device in the terminal such as VRAM.

  FIG. 4 schematically shows the Chinese numeral “1”. If the area required to display “one” is, for example, 16 dots long and 16 dots wide, “1” is displayed by dividing the area into black dots and white dots. . In the case of FIG. 4, the dot counting unit 4 counts that the dots displayed in black are 18 dots. Thus, for each character, the number of dots actually used on the display device to display the character (for example, the number of dots displayed in black) is counted, so that the character is displayed in the entire sentence. It is possible to calculate the number of dots that are used for this purpose. By dividing the calculated number of dots by the reference total number of dots, the ratio of dots used for displaying text characters (for example, the ratio of black dots) can be obtained. This is a density indicating how densely the characters are displayed in the entire sentence. Even if the text has the same number of characters, the higher the density, the more difficult the text to read, and the lower the density, the easier the text to read. The determination is performed by the processing of the determination unit 5 below.

  Note that the dot count unit 4 may count either the number of dots used for displaying text characters or the number of dots used for display. In the former case, once the display is performed on the display device, the display is automatically changed. In the latter case, the display device is automatically changed and the display is changed. Display will be performed. In the following description, the former case will be described, but the same processing can be performed in the latter case.

  The determination unit 5 determines the number of dots in the entire sentence based on the reference total dot number calculated by the reference total dot number calculation unit 3 and the dot number used for displaying the character calculated by the dot count unit 4. Calculate the percentage of. Based on this ratio, it is determined whether or not to perform scroll control change processing for the text read by the text reading unit 2. The scroll control includes a change in scroll speed and a scroll amount when automatic scrolling is performed.

  The scroll control processing unit 6 is changed when a scrolling instruction is given to the text read by the text reading unit 2 when the determination unit 5 determines to change the text scroll control. Scrolling is performed based on the scroll control. For example, it is set that the scroll speed in the case of automatic scrolling is reduced as the scroll control, and when the determination unit 5 determines to perform the scroll control change process (decrease the scroll speed), For automatic scrolling of text displayed on the display device, the scroll control processing unit 6 performs control to perform automatic scrolling at a scroll speed slower than the normal scroll speed. In addition, when the scroll amount is set to be reduced as scroll control, and the determination unit 5 determines to perform the scroll control change process (decrease the scroll amount), the text displayed on the display device of the terminal When the user receives a terminal scroll instruction (for example, pressing a down button), the scroll control processing unit 6 performs scrolling with a scroll amount smaller than the normal scroll amount (in the case of automatic scrolling). Controls to reduce the amount of scrolling per time).

  Next, an example of the processing process of the present invention will be described with reference to the flowchart of FIG. 2 and the conceptual diagram of FIG. In this specification, the case where an electronic mail received by a mobile terminal is displayed will be described. However, the present invention can be similarly realized even for a sentence on a website or other sentences.

  When displaying the e-mail received by the portable terminal, the e-mail text is read by the text reading unit 2 (S100). The text read at this time may be only the text of the e-mail, or may further read information included in the e-mail header such as the subject, destination, and sender.

  When the e-mail text is read by the text reading unit 2, the reference total dot number calculation unit 3 counts the number of characters included in the text read in S100 (S110). At this time, in addition to characters (“characters” in a narrow sense), numbers, symbols, marks (pictograms), etc. may be counted (that is, “characters” in a broad sense) are counted.

  The reference total number of dots in the sentence is calculated by multiplying the number of characters read in S110 by a preset average size of an area necessary for displaying one character (S120).

  For example, when the number of characters of the text read in S100 is 52 characters and the average size of the area necessary to display one character is set to 24 dots vertically and 24 dots horizontally, the reference total number of dots Can be calculated by the reference total dot number calculation unit 3 as 29,952 dots (= 52 × 24 × 24).

  Next, the dot count unit 4 counts the number of dots actually used to display characters in the text read by the text reading unit 2 (S130). For example, in the case of a display device that displays characters in black and the background in white, for all characters in the read text, count the number of black dots that make up one character and calculate the sum of each character The number of dots used to display characters in the read text can be obtained. For example, it is assumed that there is a “one” character shown in FIG. It is counted that 18 dots are used to display this “one”. This is counted for each character of the sentence, and the sum of them is calculated. For example, assume that the number of dots actually used for text display (the number of black dots) is 7,200 dots.

After calculating the reference total number of dots in S120 and the number of dots used to display the characters used in the text in S130, the determination unit 5 calculates the ratio of the number of dots used (S140). . This can be calculated as shown in Equation 2.
(Equation 2)
Number of dots used to display text characters / reference total number of dots × 100

  In the case of the above example, the ratio calculated in S140 is 24% (= 7,200 ÷ 29,952 × 100).

  The determination unit 5 compares the ratio calculated in Equation 2 (24% in the above example) with a predetermined reference value (for example, 20%), and reads the text read by the text reading unit 2 (e-mail in FIG. 4). It is determined whether or not to change the scroll control (S150). For example, when the reference value is set as 20% and the ratio calculated in Equation 2 (24% in the above example) exceeds the reference value (20%), it is determined to change the scroll control. When the change is to be made, the content of the scroll control is determined according to the ratio calculated by the determination unit 5 in Formula 2 and how far the ratio deviates from the reference value. The read sentence is displayed on the display device. When scroll control is instructed, the scroll control processing unit 6 performs scroll control based on the changed control content (S160).

  For example, in the scroll control change process, if the ratio calculated in Equation 2 exceeds the reference value, it is assumed that the change of the scroll speed in the case of automatic scrolling is set accordingly. Then, it is assumed that the ratio calculated in Equation 2 is 24% and the reference value is 20%. When the e-mail text displayed on the display device of the terminal is automatically scrolled, the scroll control processing unit 6 controls the automatic scrolling at a scroll speed that is 0.8 times the normal speed.

  Further, as the scroll control changing process, when the ratio calculated in Equation 2 exceeds the reference value, it is assumed that the change of the scroll amount in the case of automatic scrolling is set accordingly. Then, it is assumed that the ratio calculated in Equation 2 is 24% and the reference value is 20%. When the text of the e-mail displayed on the display device of the terminal is automatically scrolled, the scroll control processing unit 6 performs one-half of the normal scroll amount (one line) (one-half) It will be scrolled with the scroll amount of one line). Therefore, even if the scroll speed is the same, the scroll amount is reduced, so that readability is improved.

  Further, as the scroll control changing process, when the ratio calculated in Equation 2 exceeds the reference value, it is assumed that the change of the scroll amount in the case of manual scrolling is set accordingly. Then, it is assumed that the ratio calculated in Equation 2 is 24% and the reference value is 20%. When the text of the e-mail displayed on the display device of the terminal is manually scrolled (when the user of the terminal presses a button for scrolling), the scroll control processing unit 6 performs one scroll. Scrolling is performed with a scroll amount that is one-half (one-half line) of the normal scroll amount (one line). Therefore, even if the scroll speed is the same, the scroll amount is reduced, so that readability is improved.

  By performing such processing, it is possible to change the scroll speed and the scroll amount in consideration of the readability and difficulty of reading the text displayed on the display device of the terminal.

  Of the above scroll control, the concept of changing the scroll speed is schematically shown in FIG. Further, in the scroll control, the concept of changing the scroll amount is schematically shown in FIG.

  Note that, as a result of the comparison in S150, the scroll speed and the scroll amount can be adjusted stepwise according to the degree to which the ratio calculated in Equation 2 exceeds the reference value. That is, the scroll speed and the scroll amount may be changed in accordance with the degree (plus 4%) that the ratio (for example, 24%) calculated in Equation 2 exceeds the reference value (for example, 20%). .

  By performing the processing as described above, the text displayed on the display device of the terminal becomes easy to read.

  In addition to mobile terminals and personal computers, the above-mentioned terminals include mobile devices such as railways and buses, display devices that are installed at intersections, etc., and display information such as news using characters, etc. A device (teloper) for displaying a telop on the screen is also included.

  Next, the case where the scroll control system 1 is provided in the display device installed on the Shinkansen will be described. In addition, it is assumed that the text information to be displayed has already been captured in this display device, which is shown in FIGS.

  In the case of the scroll control system 1 of the present invention, first, the text reading unit 2 reads the text in FIG. 7A (S100), and the reference total dot number calculation unit 3 counts the number of characters (S110). This is 35 characters. Next, the reference total dot number calculation unit 3 calculates the reference total dot number per character number (35 characters) (S120). Then, the dot count unit 4 counts the number of dots used for displaying the text in FIG. 7A when displaying on the display device (S130). Then, the number of dots calculated in S130 and the reference number of dots are calculated using the above-described number 2, and the ratio of the number of dots used for displaying the text is calculated (S140). The determination unit 5 compares this ratio with a preset reference value to determine whether or not to change the scroll control (S150). For example, if the ratio of the number 2 in FIG. 7A is 35% and the reference value is 20%, it is determined to change the scroll control.

  If this control is a scroll speed control, for example, using FIG. 5, the scroll control processing unit 6 scrolls the text of FIG. 7A at a normal scroll speed of 0.6 times. Become. If the scroll control is a control for scrolling, for example, the scroll amount per one time is scrolled as a normal scroll amount by using FIG.

  The same processing is performed for the sentence in FIG. 7B, but in the case of FIG. 7B, for example, the ratio calculated in Equation 2 is 18%, and the reference value is 20%. For example, it is determined that scroll control is not performed.

  As described above, each of the sentences in FIGS. 7A and 7B has 35 characters, but the sentence in FIG. 7A in which the percentage of dots used for character display is high is different from the normal one. Scroll control is performed. On the other hand, the normal scroll control is performed for the text in FIG. That is, even if the total number of characters is the same, scroll control suitable for the text displayed on the display device of the terminal is performed.

  By using the present invention, it is possible to control scrolling at a scrolling speed and a scrolling amount suitable for readability of text displayed on a terminal and difficulty in reading.

Further, since the number of characters is not determined as in the prior art, more accurate text scroll control can be performed. In other words, even if the text has the same total number of characters, if the number of dots used for character display is small, the text is scrolled at the normal scrolling speed and scroll amount, while if the number of dots used for character display is large. Sentences are scrolled at a slower speed and a smaller scroll amount than usual. Furthermore, since processing is not performed in units of characters, characters that are enlarged in one sentence and characters that are not enlarged are not mixed. In addition, since the determination is not performed based on the number of strokes of characters, it is not necessary to store information on the number of strokes of each character, and the device can function effectively even in a portable terminal having a small storage area.

It is a conceptual diagram which shows an example of the system configuration | structure of this invention. It is a flowchart which shows an example of the processing process of this invention. It is a figure which shows typically comparing the legibility of the text with the same number of characters. It is a figure which shows typically the dot currently used for the character. It is a figure which shows the change of scroll speed typically. It is a figure which shows the change of scroll amount typically. It is an example of sentences.
