  Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

  First, a first embodiment of the present invention will be described.

  As shown in FIG. 3, the text decoration system 1 includes operation information acquisition means 4 for acquiring operation information by the pointing device 3, and position information for acquiring position information for specifying a line drawn by the pointing device 3 from the operation information. The acquisition unit 5, the operation screen information acquisition unit 7 for acquiring information of the operation screen displayed on the display unit 10, and the character region information for acquiring the character region information from the operation screen information of a part or all of the region of the operation screen Acquisition means 8, decoration determination means 6 for determining the decoration type of the character based on the character area information acquired by the character area information acquisition means 8 and the position information acquired by the position information acquisition means 5, and the decoration determination There is provided a decoration display means 9 for displaying a decoration line of characters on the operation screen according to the decoration type determined by the means 6. The character decoration system 1 functions as each unit by installing the character decoration program 2 in a computer C such as a terminal. The computer C includes a pointing device 3, a display unit 10, a processing unit (not shown), and a recording unit. Each means may be realized by hardware or software. The computer C may be composed of, for example, one or a plurality of terminals, or may be composed of a server and a client terminal in a server / client system.

  The processing unit is a CPU that controls each device, calculates and processes data, and the recording unit is a device that records information, a program, and the like, and temporarily stores an external recording device such as a hard disk and information. Includes a semiconductor recording device for recording. The pointing device 3 is an input device that operates the computer C by moving the cursor 12 on the operation screen and specifying a position, and is, for example, a mouse, a touch screen, a pen tablet, a track pad, or a track ball. The display unit 10 has an operation screen, and displays characters, a line 13 drawn by the pointing device 3, and the like on the operation screen.

The operation information acquisition unit 4 monitors whether or not a line is drawn with the pointing device 3 from the operation content of the operation information, and identifies a line drawn with the pointing device (hereinafter referred to as “drawn line”). The operation information including the position information to be acquired is acquired, the acquired operation information is transmitted to the position information acquisition means 5, and the fact that it has been detected is transmitted to the operation screen information acquisition means 7. For example, when it is detected that the final content indicating that a line such as button release has been drawn is included in the operation content, operation information related to the drawn line, that is, a start indicating the beginning of drawing a line such as a button press Operation information for identifying a drawn line from the process to the end process indicating the end of line drawing, such as button release, is acquired and transmitted to the position information acquisition means 5.

  Here, the operation information is generated by an operation by the pointing device 3, for example, an operation content indicating that a line has been drawn by a position specifying operation such as button pressing, button release, or movement by the pointing device 3, and the cursor of the operation It includes coordinate information indicating a position, coordinates, etc., date and time when operation information is generated, or date and time information indicating a count time from the start to the end of the operation. Further, the operation information can include, for example, terminal identification information for identifying a terminal on which an operation has been performed, and user identification information for identifying a login user of the terminal.

  The position information acquisition means 5 acquires position information for specifying the drawn line 13 from the coordinate information of the operation information related to the drawn line. In this example, the position information acquisition means 5 transmits this position information to the decoration determination means 6. ing. The line 13 drawn here includes a locus line 13a and a virtual line 13b. Further, as shown in FIG. 1A, the locus line 13a is a locus of the cursor 12 moved from the start to the end of the position specifying operation of the pointing device 3, and the virtual line 13b is shown in FIG. In this way, the line connects the start position 14a and the end position 14b specified by the pointing device.

  Here, the position information for identifying the drawn line 13 is an expression representing the drawn line 13 from the coordinate information of the operation information related to the drawn line 13, and the position coordinates calculated from the expression or the expression. Etc. Note that the position information for specifying the drawn line 13 is not limited to the position coordinates calculated from the formula or the formula, and may be the coordinate information related to the drawn line 13 without obtaining the formula.

  That is, when the drawn line is the trajectory line 13a, the position information specifying the trajectory line 13a is obtained, for example, by calculating an approximate expression from a set of coordinate information to which the cursor 12 has moved, and the position coordinates representing the trajectory line 13a from this approximate expression. Is obtained by calculating. Here, the coordinate information may be coordinate information of all the operation information related to the trajectory line 13a, or may be coordinate information of the operation information acquired at predetermined intervals among the operation information related to the trajectory line 13a. Good. The predetermined interval can be set every predetermined distance by referring to the coordinate information of the operation information, or can be set every predetermined time by referring to the date / time information of the operation information. When the drawn line 13 is a virtual line 13b, the position information for specifying the virtual line 13b is obtained, for example, by calculating an expression of a line passing through the start position and the end position, and calculating the position coordinates representing the virtual line 13b from this expression. It is acquired by doing.

  More specifically, when the button of the pointing device 3 is pressed (for example, clicked with the mouse) and then the button is released (for example, released with the mouse) to draw a line, the operation information indicates that the operation content is the button pressed. And coordinate information of the operation information is acquired as a start position. Also, operation information whose operation content is button release is specified, and coordinate information of the operation information is acquired as an end position. Here, in the case of the locus line 13a, the operation position from the button press to the button release is acquired from the coordinate information of the operation information. Then, an equation is calculated from the acquired coordinate information, and position information of the line 13 drawn from the equation is obtained. The position coordinates representing the drawn line are a start position, an end position, and an arbitrary or predetermined position between the start position and the end position.

  Note that the specification of the start position and the end position is not limited to this, and for example, these can be specified from date information or coordinate information of the operation information. When specifying by the date information, the date information is obtained from the operation information in addition to the coordinate information, the operation information of the earliest date is specified, and the coordinate information of the operation information is used as the position information of the start position. To do. On the other hand, the operation information with the latest date and time information is specified, and the coordinate information of the operation information is used as the position information of the end position. Further, when specifying by coordinate information, the operation information whose coordinate information is at the left end (the x coordinate is the smallest) is specified from the operation information, and the coordinate information of the operation information is used as the position information of the start position. On the other hand, the operation information whose coordinate information is at the right end (the largest x coordinate) is specified from the operation information, and the coordinate information of the operation information is used as the position information of the end position.

  The operation screen information acquisition unit 7 acquires operation screen information from the display unit 10 in response to detecting that a line has been drawn from the operation information acquisition unit 4 described above, for example. The operation screen information is transmitted to the character area information acquisition means 8. Here, the operation screen information includes image data, date information, and the like displayed on the operation screen of the display unit 10, and may include user identification information, terminal identification information, position information, and the like.

  The character area information acquisition means 8 receives the operation screen information from the operation screen information acquisition means 7 and acquires character area information of a part or all of the operation screen. In this example, the acquired character area information Is transmitted to the decoration determination means 6.

  Here, as shown in FIG. 2, the character area information includes character information indicating the character 15 displayed on the operation screen and information on the character description area 16a indicating an area where a series of characters are arranged (hereinafter referred to as “character description area”). Information "). The character information is specified by analyzing the operation screen information by a method such as pattern recognition, and includes a character displayed on the operation screen, a display position of the character, and the like. The characters 15 include not only words that describe words such as hiragana, kanji, and alphabet, but also numbers and symbols. The display position includes the lower end position, the upper end position, the right end position, and the left end position of the character 15, and the character width 16e is obtained from the difference between the right end position and the left end position. The character description area 16a is specified from the character information. For example, the interval between adjacent characters is calculated from the display position of the character information, and if the character interval is smaller than a predetermined value, it is determined that the adjacent characters are arranged in a series, and the region of these characters is specified as the character description region . The character description area information includes a lower limit 16c indicating the lower limit of the character description area, an upper limit 16d indicating the upper limit, a right edge 16g indicating the right end, and a left edge 16f indicating the left end, each of which is included in the character description area. It is obtained from the upper end position, lower limit position, right end position, and left end position of the character.

  The decoration determination means 6 receives the position information for specifying the line 13 drawn from the position information acquisition means 5 and the character area information from the character area information acquisition means 8, and determines the decoration type of the character based on these. In this example, the decoration determination means 6 includes a decoration type determination means 6a, and the decoration type determination means 6a determines the decoration type. Specifically, the ratio of the drawn line included in the character description area (hereinafter referred to as the ratio of the line) is obtained from the position information and the character area information, and an expression showing the relationship between the ratio of the line and the decoration type The decoration type is acquired from the ratio of lines using a predetermined standard such as a table or a table.

  Here, the decoration type is a rule for converting the drawn line 13 into a decoration line, such as a line shape such as a straight line or a wavy line, a line type such as a solid line or a broken line, a center of the line, an underline, etc. Includes position, color, and line width. The decoration line is a line attached to the character 15 in order to decorate the character 15, and is determined by the drawn line 13 and the decoration type. For example, the decoration type is determined based on the ratio of the drawn line 13 included in the character description area 16a.

  More specifically, the decoration determination means 6 specifies the upper limit 16d and the lower limit 16c of the character description area 16a from the character description area information of the character area information. Next, it is determined whether or not the position coordinates specifying the drawn line 13 are located between the upper limit 16d and the lower limit 16c of the character description area 16a, and if so, the position is included in the character description area. . This is repeatedly determined for all or some of the position coordinates representing the drawn line 13. Then, the ratio of the number of position coordinates included in the character description area 16a is calculated with respect to the determined number of position coordinates, and the ratio of the drawn lines included in the character description area 16a is obtained.

  For example, as shown in FIG. 4A, when the line 13 is drawn by the pointing device 3, the decoration determination means 6 specifies the y-coordinates of the upper limit 16d and the lower limit 16c, and here the upper limit is “172”. The lower limit is specified as “138”. Next, each position coordinate is included between the character description areas “138 to 172” between the upper limit and the lower limit from the position information made up of the x coordinate and the y coordinate specifying the drawn line 13 shown in FIG. It is determined whether or not. In this example, the number of all position coordinates is “17”, and the number of position coordinates included in the character description area is “10”. Then, “59%” is calculated as the ratio of the number “10” of position coordinates included in the character description area 16a to the number “17” of all position coordinates, and this is the ratio of the drawn line.

  As another example, when the drawn line 13 is a straight line, it is determined whether the start position and the end position of the drawn line 13 are located in the character description area 16a. When both the start position and the end position are located in the character description area 16a, the drawn line 13 is included in the character description area 16a. Therefore, the ratio of the drawn line included in the character description area 16a is 100%. become. When both the start position and the end position are not located in the character description area 16a, the ratio of the drawn line included in the character description area 16a is 0%. Further, as shown in FIG. 5, the distance Y1 between the y-coordinate of the start position and the y-coordinate of the end position and the distance Y2 between the lower limit 16c of the character description area and the y-coordinate of the end position are obtained, and the latter with respect to the former The ratio Y2 / Y1 may be the ratio of the drawn line included in the character description area 16a.

  From the ratio of the line 13 thus obtained, the decoration type determination means 6a determines the decoration type according to the relationship standard between the line ratio and the decoration type. For example, the decoration type such as the line type and the line width is determined from the threshold for the ratio of the drawn line 13 included in the character description area 16a. For example, as shown in FIG. 7, the relationship between the ratio and the decoration type is set. In this case, as shown in FIG. 6A, when the ratio of the drawn line 13a included in the character description area 16a is 75% or more, the marker display is decorated with the shape, line width, color and the like as shown in FIG. The type is determined. Further, as shown in FIG. 6B, when the ratio of the drawn line 13a included in the character description area 16a is less than 75% and 35% or more, the shape and line are displayed as a wavy underline display as shown in FIG. Decoration types such as width and color can be determined. Furthermore, when the ratio of the drawn line 13a included in the character description area 16a is less than 35% as shown in FIG. 6C, the shape, line width and color are displayed as a linear underline display as shown in FIG. The decoration type such as can be determined. For example, in the case of FIG. 4, the ratio of the drawn line 13a included in the character description area 16a is “59%”, and the decoration type such as shape, line width, and color is determined as the wavy underline display.

  Further, the decoration determination means 6 determines the decoration range of the decoration line from the position information specifying the drawn line 13. The decoration range is a range in which a decoration line is displayed. For example, the decoration range can be between the x coordinate of the start position of the drawn line 13 and the x coordinate of the end position, or the start of the drawn line. It can be between the x-coordinate and y-coordinate of the position and the x-coordinate and y-coordinate of the end position, and the drawn line can be used as a decoration range. When the decoration range is between the x coordinate of the start position and the x coordinate of the end position of the drawn line 13, the y coordinate of the decoration range is determined in a predetermined or arbitrary manner. For example, in the entire range of the decoration range, the y coordinate of the start position, the y coordinate of the end position, or the y coordinate between the start position and the end position can be used. Further, when the decoration type defines marker display or underline, the marker display is set between the upper limit and the lower limit of the character description area, and the lower limit display is set for the underline display. Then, the decoration determination unit 6 transmits the determined decoration type and decoration range to the decoration display unit 9.

  The decoration display means 9 receives the decoration range and decoration type from the decoration determination means 6 and displays the decoration line of characters on the operation screen of the display unit 10 according to these. For example, when the decoration range is between the x coordinate of the start position and the end coordinate of the drawn line 13, the decoration line determined by the decoration type is displayed in the character description area of the decoration range. In the case of the line 13 with the decoration range drawn, the decoration line determined by the decoration type is displayed at the position of the drawn line 13.

  Next, the processing flow of the character decoration system 1 will be described with reference to FIG.

  First, the operation information acquisition means 4 acquires operation information (S1), and monitors whether or not a line is drawn by the pointing device 3 from the operation content of the operation information (S2). When it is detected that the line is drawn by the pointing device 3, the operation information related to the drawn line 13 is transmitted to the position information acquisition unit 5, and the detection information is transmitted to the operation screen information acquisition unit 7. The operation screen information acquisition unit 7 receives the detection of the line 13 drawn by the operation information acquisition unit 4 and acquires operation screen information of the image image displayed on the operation screen of the display unit 10 based on the detection (S3). The operation screen information is transmitted to the character area information acquisition means 8.

  Next, the character area information acquisition means 8 acquires the operation screen information of the operation screen from the operation screen information acquisition means 7, and acquires the character area information from the operation screen information (S4). That is, as shown in FIG. 2, the character 15 is specified from the operation screen information, the character information such as the character width 16e is acquired, the character description region 16a is specified from the character information, and the character description region information is acquired. To do. Then, the character description area information is transmitted to the decoration determination means 6.

  When the pointing device 3 detects that a line has been drawn, the position information acquisition unit 5 acquires operation information related to the drawn line 13, and an expression representing the line drawn from the coordinate information of the operation information. Is obtained as position information for specifying the line 13 from which the position coordinates are drawn (S5). Further, when the drawn line is a virtual line 13b as shown in FIG. 1B, the positions 14c and 14c according to the formulas obtained from the coordinate information of the start position 14a and the end position 14b specified by the position specifying operation. ,... Is a set of position coordinates. When the position information is acquired, the position information acquisition unit 5 transmits position information for specifying the drawn line 13 to the decoration determination unit 6.

  Next, the decoration determination means 6 calculates the ratio of the drawn line included in the character description area 16a based on the position information and the character description area information (S6), and determines the decoration type from the ratio (S7). . For example, the decoration type such as shape, line width, and color is determined from the relationship between the ratio and the decoration type shown in FIG. Further, the decoration determination means 6 determines the decoration range from the position information that identifies the drawn line (S8). Next, the decoration display means 9 receives the decoration range and the decoration type, and displays the decoration line in the decoration range (S9).

  As described above, when the proportion of the line is large, it is determined that there is a high possibility that a line is drawn in the character description area, and the decoration type is determined so that the decoration line is displayed in the character description area. On the other hand, if the percentage of the line is small, it is unlikely that a line is drawn in the character description area. For example, it is determined that the line is drawn below the character description area. As a result, the decoration type is determined. For this reason, the user's intention can be determined based on the relationship between the entire drawn line and the character description area, and the decoration line can be displayed. Moreover, since it is judged by the whole drawn line, it is not necessary to draw a line accurately, and the operability is excellent. Furthermore, the decoration range and decoration type can be determined by one operation of drawing a line, and the operability is excellent. In the above embodiment, marker display or underline display is determined based on the line ratio. However, the present invention is not limited to this, and the line shape, line type, line width, position, and combination of the decorative lines are determined according to the line ratio. The decoration type such as can be determined.

  Next, a second embodiment of the present invention will be described.

  The character decoration system 1 according to the present embodiment determines the decoration type based on the length of the line 13 drawn by the pointing device 3 and the linear distance between the start position and the end position of the drawn line 13. The length of the drawn line 13 is a length along the drawn line 13 and is calculated from position information for specifying the drawn line 13. For example, it is obtained by calculating the distance between adjacent positions from each position coordinate of the position information and integrating the distances.

  The decoration determination means 6 receives the position information for specifying the line 13 drawn from the position information acquisition means 5 and the character area information from the character area information acquisition means 8, and determines the decoration type of the character based on these. . The decoration determination means 6 includes a decoration type determination means 6a, and the decoration type determination means 6a determines the decoration type. Specifically, the length L of the line drawn from the position information and the straight line distance S between the start position and the end position of the drawn line are obtained, compared, and the relationship between the comparison result and the decoration type The decoration type is acquired from the comparison result between the line length L and the straight line distance S using a predetermined criterion such as an expression or a table indicating the above.

  More specifically, for example, as shown in FIG. 9A, the decoration type is based on the length of the drawn line 13 and the linear distance S between the start position 19a and the end position 19b of the drawn line 13. Is determined. The length of the drawn line 13 is obtained by calculating the distance between points constituting the drawn line 13 from the position information of the drawn line 13 specified by the position information acquiring means 5, and adding them to obtain the distance. calculate. Further, the decoration determination means 6 calculates a linear distance (hereinafter referred to as “linear distance”) S between the start position 19 a and the end position 19 b of the drawn line 13.

  For example, as shown in FIG. 10 (a), when the line 13 is drawn by the pointing device 3, the decoration determining means 6 is drawn when the position information is obtained as shown in FIG. 10 (b). The distance between adjacent positions is calculated from the position information consisting of the x coordinate and the y coordinate specifying the line 13, the calculated distances between adjacent positions are integrated, and the length L of the drawn line 13 is calculated. Further, the straight line distance S is calculated from the coordinates of the start position 19a and the end position 19b of the drawn line 13. In this case, as shown in FIG. 10C, the length L of the drawn line 13 is calculated as “129.1”, and the straight line distance S is calculated as “80.0”.

  Then, the decoration determination unit 6 compares the length L of the drawn line 13 with the linear distance S. For example, the ratio of the length L of the drawn line 13 to the linear distance S (L / S), and the line drawn by the difference (LS) obtained by subtracting the linear distance S from the length L of the drawn line 13. The length of 13 and the linear distance S can be compared. Then, the decoration type is determined based on the comparison result. In the case of FIG. 10B, as shown in FIG. 10C, the ratio (L / S) of the length L of the drawn line 13 to the straight line distance S is “1.6”. The difference (LS) between the line length L and the straight line distance S is calculated as “49.1”.

  The decoration determination means 6 calculates the ratio of the length of the drawn line 13 and the straight line distance S, the difference in distance, and the like, and determines the decoration type based on the ratio, the difference in distance, and the like. Specifically, when the ratio of the length of the drawn line 13 to the straight line distance S is obtained, the decoration type such as the line type and the line width is determined from the threshold value for the ratio indicating the relation standard between the ratio and the decoration type. It is decided. For example, the ratio (L / S) when the length L of the line 13 drawn from the straight line distance S is 1.2 times longer and the length L of the line 13 drawn from the straight line distance S are 1.5 times longer. If the ratio (L / S) is a threshold value and the ratio is less than 1.2, the decoration type of the linear line type is determined, and if the ratio is 1.2 or more and less than 1.5, the wavelength is long. The decoration type of the wavy line type is determined. If the ratio is 1.5 or more, the decoration type of the line type on the wavy line having a wavelength shorter than the wavelength when the ratio is 1.2 or more and less than 1.5 is determined. The

  Further, as described in the first embodiment, the decoration determination unit 6 determines the decoration range of the decoration line from the position information that specifies the drawn line 13. The decoration display unit 9 receives the decoration range and the decoration type from the decoration determination unit 6 and displays the decoration line 20 on the operation screen 25. For example, as shown in FIG. 9B, when the length L of the drawn line 13 is 100.3 and the linear distance S is 85, the ratio is 1.18, and the start position 19a of the drawn line 13 is In the decoration range between the x-coordinate and the x-coordinate of the end position 19b, a linear decoration line 20b is displayed at the lower limit of the character description area. 9C, when the length L of the drawn line 13 is 117.3 and the linear distance S is 85, the ratio is 1.38, and the start position 19a of the drawn line 13 is In the decoration range between the x-coordinate and the x-coordinate of the end position 19b, a wavy line-shaped decoration line 20c having a long wavelength is displayed at the lower limit of the character description area. Further, as shown in FIG. 9D, when the length L of the drawn line 13 is 138.6 and the straight line distance S is 85, the ratio is 1.63, and the start position 19a of the drawn line 13 is In the decoration range between the x coordinate and the x coordinate of the end position 19b, a wavy decorative line 20d having a short wavelength is displayed at the lower limit of the character description area. In this example, the wavelength of the predetermined wave line is obtained from the threshold value with respect to the ratio, but the wavelength of the wave line can also be calculated from the length of the line drawn using the wave calculation formula and the straight line distance.

  In the processing flow of the character decoration system 1 in this embodiment, the description of the same parts as those in the above embodiment is omitted. In step 6 (S6) of FIG. 8, the decoration determination means 6 calculates the length L of the drawn line 13, and calculates the linear distance S from the start position 19a and the end position 19b of the drawn line 13. The length L of the drawn line 13 is compared with the straight line distance S. In step 7 (S7), the decoration type determination means 6a determines the decoration type based on the comparison result. In step 8 (S8), the decoration determination means 6 determines the decoration range from the character description area information and the position information. To do. And the decoration display means 9 receives a decoration range and a decoration classification, and displays a decoration line in a decoration range (S9).

  As described above, when the length L is smaller than the linear distance S as a result of the comparison between the length L of the drawn line and the linear distance S, the length L is close to the linear distance, that is, the drawn line. Is determined to be a straight line, and the decoration type is determined so that the decorative line is displayed in a straight line. On the other hand, if the length L is longer than the straight line distance S, it is determined that there is a high possibility that the drawn line is wavy, and the decoration type is determined so that the decoration line is displayed on the wavy line. Furthermore, if the length L is much longer than the linear distance S, it is determined that there is a high possibility that the wave number of the wavy line is large or the amplitude of the wave is large. The decoration type is determined so that a wavy line whose shape is changed is displayed. For this reason, the user's intention can be determined based on the relationship between the entire drawn line and the straight line, and the decoration line can be displayed. Moreover, since it is judged by the whole drawn line, it is not necessary to draw a line accurately, and the operability is excellent. Furthermore, the decoration range and decoration type can be determined by one operation of drawing a line, and the operability is excellent.

  Since other configurations and modifications are basically the same as those in the first embodiment, description thereof will be omitted.

  In FIG. 9, the line shape of a decoration line such as a straight line or a wavy line is determined based on the ratio between the straight line distance S and the length of the drawn line 13, but the line type of the decoration line is determined based on the ratio. It is also possible to determine a decoration type such as a combination of line width, color, and position. In the above-described embodiment, the decoration type is determined based on the ratio of the length of the drawn line to the straight line distance. Similarly, the decoration type is determined by the difference between the length of the drawn line and the straight line distance. Can be determined.

  Next, a third embodiment of the present invention will be described.

  In the present embodiment, the decoration type is determined based on the operation speed when the drawn line 13 is drawn, and various methods can be considered as a method for calculating the operation speed. In this example, the decoration determination is performed. The means 6 receives the position information specifying the line drawn from the position information acquisition means 5 and the date information of the operation information, calculates the operation time from the date information, and calculates the operation speed from the position information and the operation time.

  The position information acquisition means 5 obtains the position information for identifying the line 13 drawn from the coordinate information of the operation information related to the drawn line, and sets the start position and end position based on the operation content, date information, coordinate information, etc. Identify. Further, the date and time information of the start position and the end position is acquired from the operation information. The acquired position information and date / time information are transmitted to the decoration determination means 6.

  The decoration determination means 6 receives the position information specifying the line 13 drawn from the position information acquisition means 5 and the date / time information of the operation information, and the character area information from the character area information acquisition means 8, and from the position information and the date / time information. The operation speed is calculated, and the decoration type of the character is determined based on the operation speed. The decoration determination means 6 includes a decoration type determination means 6a, and the decoration type is determined by the decoration type determination means 6a. This decoration type is determined from the operation speed using a predetermined standard such as an expression or a table showing the relationship between the operation speed and the decoration type.

  For example, when the line 13 is drawn by the pointing device 3 as shown in FIG. 10A described above, the decoration determination means 6 identifies the drawn line 13 as shown in FIG. The distance between the adjacent positions is calculated from the position information including the coordinates and the y-coordinate, the calculated distances between the adjacent positions are integrated, and the length L of the drawn line 13 is calculated as “129.1”.

  Also, the difference between the date and time information of the start position and the date and time information of the end position, for example, from June 20, 2008 AM 10:53:35 to June 20, 2008 AM 10: 53: 40.5. The operation time T is calculated from 5 seconds or the like. The decoration determination unit 6 associates the date and time information with the position information and acquires it from the position information acquisition unit 5, and the operation time T is calculated from the date and time information of each position point to the adjacent position points as shown in FIG. It is also possible to calculate “5.50” by calculating the time difference between the two.

  Then, the operation speed (L / T) is calculated as “23.5” from the length L and the operation time T as shown in FIG.

  For example, the color of the marker display is set as the decoration type with a threshold value for the operation speed indicating the relational standard between the operation speed and the decoration type. Specifically, when the operation speed is 20 or more, the color is dark, and when the operation speed is less than the value 20, the color is light. In this case, as shown in FIG. 11A, when the operation speed is 23.5 as in the example of FIG. 10, the light marker display 26a is determined. Further, as shown in FIG. 11B, when the operation speed is 17.9, the dark marker display 26b at a position corresponding to the decoration range of the operation screen 25b is determined. Although the decoration type is determined by the threshold value of the operation speed, the present invention is not limited to this. For example, the color shade can be changed according to the operation speed.

  Further, as described in the first embodiment, the decoration determination unit 6 determines the decoration range of the decoration line from the position information that specifies the drawn line 13. The decoration display means 9 receives the decoration range and decoration type from the decoration determination means 6 and displays a decoration line 26 on the operation screen 25. For example, in the case of FIG. 11, the position corresponding to the decoration range is displayed with a light marker display 26a and a dark marker display 26b according to the decoration type.

  In the processing flow of the character decoration system 1 in this embodiment, the description of the same parts as those in the above embodiment is omitted. In step 6 (S6) in FIG. 8, the decoration determination means 6 operates from the start position to the end position when the pointing device 3 is drawn based on the date information of the operation information acquired by the operation information acquisition means 4. And the length L of the line 13 drawn from the position information is calculated. Then, the operation speed (L / T) is calculated from the length L of the drawn line 13 and the operation time T (S6). Furthermore, in step 7, the decoration determination means 6 determines the decoration type based on the operation speed (L / T) and the character description area information (S7). Further, the decoration determination means 6 determines the decoration range from the position information that identifies the drawn line (S8). And the decoration display means 9 receives a decoration range and a decoration classification, and displays a decoration line in a decoration range (S9).

  As described above, when the operation speed is low, the cursor of the pointing device moves slowly. For example, when the cursor is regarded as a pen, it is determined that there is a high possibility that the pen contact time is long and the amount of ink supply increases. The decoration type is determined so that the color of the decoration line is darkly displayed. On the other hand, if the operation speed is low, the cursor of the pointing device moves quickly. For example, when the cursor is regarded as a pen, it is determined that there is a high possibility that the pen contact time is short and the ink supply amount is low. The decoration type is determined so that the color of the decoration line is displayed lightly. For this reason, the user's intention can be determined based on the overall length of the drawn line and time, and the decoration line can be displayed. Moreover, since it is judged by the whole drawn line, it is not necessary to draw a line accurately, and the operability is excellent. Furthermore, the decoration range and decoration type can be determined by one operation of drawing a line, and the operability is excellent.

  Other configurations and modifications are basically the same as those in the above-described embodiment, and thus the description thereof is omitted.

  In the above-described embodiment, the color shade is determined based on the speed. However, the present invention is not limited to this, and the decoration type such as the line shape, line type, line width, position, and combination thereof can be determined according to the speed. .

  In all the embodiments described above, the decoration range is obtained from the position information of the drawn line, and the drawn line itself and the start position and the end position are determined as the decoration range. However, the present invention is not limited to this. For example, it is possible to specify a target character of a decoration character from character area information and position information, and set the target character as a decoration range.

  The target character is a character decorated with a decorative line among characters displayed on the operation screen. For example, it is determined based on the positional relationship between the drawn line 13 and the character on the operation screen, and the character included in the range of the drawn line 13 in the x direction can be used as a decoration target. A character including a line drawn in the width can be set as a decoration target. Further, the relationship with the drawn line 13 can be determined in units of characters, or can be determined by a word that is a combination of characters. When judging by a word, it has the word specific | specification part which specifies a word from a character with reference to a dictionary.

  Specifically, as shown in FIG. 12, the decoration type determination means 6 includes a decoration type determination means 6a and a decoration character specification means 6b. The decoration type determination means 6a determines the decoration type and the decoration character specification means 6b. The target character for character decoration is specified by. Further, the decoration character specifying unit 6b receives the position information specifying the line 13 drawn from the position information acquisition unit 5 and the character area information from the character region information acquisition unit 8, and specifies the character to be decorated Character information is acquired and sent to the decoration display means 9. That is, the x-coordinate of the start position and the x-coordinate of the end position are acquired from the position information specifying the drawn line, and the space between these is set as the decoration target area. Then, the decoration target area is compared with the x-coordinates of the left end position and the right end position of the display position of each character included in the character area information, the character corresponding to the decoration target area is set as the target character, and the target character is decorated. Specify as a range.

  More specifically, as shown in FIG. 14, a region between the x coordinate 26.5 of the start position and the x coordinate 105.55 of the end position acquired from the position information specifying the drawn line is set as a decoration target region. The decoration target area is compared with the x coordinate of the left end position and the right end position of the display positions of “A”, “I”, “U”, “E”, “O”, and “KA” included in the character area information. In this case, since the left end position and the right end position of each character of “I”, “U”, “E”, and “O” are included in the decoration target area, the ratio of the drawn line to the character width is 100%. . On the other hand, since the left end position of “A” is 18 and the right end position 35, the ratio is 50%, the left end position of “KA” is 103, and the right end position is 120. The ratio is 15%. At this time, when the criterion for determining whether or not to be a target character is 40%, “A”, “I”, “U”, “E”, and “O” are specified as target characters. Then, the width M of the target character, that is, the space between the left end position x coordinate of the display position of the target character and the x coordinate of the right end position is sent to the decoration display means 9 as a decoration range.

  Further, the decoration display means 9 receives the decoration type and the target character information from the decoration determination means 6 and displays the decoration line 17 over the area of the target character. For example, in the case of FIG. 14A, the character description area 16a in the entire range of “A” to “O” specified as the target character is displayed with the marker display 26a determined as the decoration type. In the case of FIG. 14B, the lower limit 16c of the entire range of “A” to “O” specified as the target character is displayed by the wavy line 17a determined as the decoration type. In the case of FIG. 14C, the lower limit 16c of the entire range of “A” to “O” specified as the target character is displayed with the decoration line 17c determined as the decoration type.

  Next, the flow of processing of the character decoration system 1 will be described with reference to FIG. In addition, description about the same part as the said embodiment is abbreviate | omitted. In step (S8), the decorative character specifying means 6b receives the position information and character area information specifying the drawn line, and specifies the target character for character decoration as the decorative range. Then, the decoration display means 9 receives the decoration range and the decoration type, and displays the decoration line in the decoration range (S9).

  In this way, when the target character is specified as a decoration range, when it is desired to decorate in character units, a decoration line in line with the user's intention can be attached to the character to be decorated, and the user can accurately specify the character to be decorated. Since it is not necessary to specify, it is excellent in operability.

  Next, a fourth embodiment of the present invention will be described.

In this embodiment, after specifying the target character of the character decoration from the character area information and the position information, the decoration type is determined based on the width M of the target character and the length of the drawn line 13. Specifically, the character string width M of the character decoration target character is compared with the length L of the drawn line, and a predetermined standard such as an expression or a table showing the relationship between the comparison result and the decoration type. Is used to obtain the decoration type from the comparison result between the width M of the character string and the length L of the line.
The width M of the character string of the target character is the width of the character string to be decorated. When there is one target character, the character string includes one character. Further, when there are a plurality of target characters, this corresponds to the distance between the left end position of the character located at the left end of the characters and the right end position of the character located at the right end.

  Specifically, as in the embodiment shown in FIG. 12, the decoration determining means 6 includes a decoration type determining means 6a and a decorative character specifying means 6b, and the decorative character specifying means 6b specifies the target character for character decoration.

  The decoration type determination unit 6 a determines the decoration type based on the width M of the character string of the character decoration target character specified by the decoration character specification unit 6 b and the length L of the drawn line 13. Specifically, the decoration determination unit 6 calculates the length L of the drawn line 13 based on the position information of the drawn line 13 acquired by the position information acquisition unit 5 as in the second embodiment. . Character area information is obtained for the target character specified by the decorative character specifying means 6b, and the width of the character string of the target character is calculated from the character area information. For example, each character width of the target character is acquired from the character area information of the target character, and is added to calculate the width M of the character string of the target character. For example, if the width of each of the target characters “A”, “I”, “U”, “E”, and “O” is 17, the width M of this character string is 17 × 5 = 85. Further, the right end position and the left end position of the character string of the target character are specified from the display position of the character area information of the target character, and the width M of the character string is calculated from the difference therebetween. For example, as shown in FIG. 16, the width M of the character string is calculated as 85 from the difference between the left end position 18 of “A” in the character string “AIUEO” of the target character and the right end position 103 of “O”.

  Then, the decoration determination unit 6 compares the length L of the drawn line 13 with the width M of the character string. For example, the ratio (L / M) of the length L of the drawn line 13 to the width M of the character string and the difference (LM) obtained by subtracting the width M of the character string from the length L of the drawn line 13 The length L of the drawn line 13 can be compared with the width M of the character string. Then, the decoration type is determined based on the comparison result.

  For example, the ratio (L / M) when the length L of the line 13 drawn from the width M of the character string is short and the length L of the line 13 drawn from the width M of the character string are 1.2 times longer. If the ratio is less than 1.0, a linear line type decoration type is determined. If the ratio is 1.0 or more and less than 1.2, the wavelength is long. The decoration type of the wavy line type is determined. If the ratio is 1.2 or more, the decoration type of the line type on the wavy line having a wavelength shorter than the wavelength when the ratio is 1.0 or more and less than 1.2 is determined. The

  As shown in FIG. 15A, when the length L of the line 13 drawn by the pointing device 3 on the operation screen 24 is 111.6 and the width M of the character string is 125, the ratio is 0.9. The linear decoration type is determined. Further, as shown in FIG. 15B, when the line length L is 143.6 and the character string width M is 125 when the line 13 is drawn on the operation screen 24 by the pointing device 3, the ratio is 1.1. Thus, a wavy line-shaped decoration type having a long wavelength is determined. Further, as shown in FIG. 15C, when the length L of the line drawn by the pointing device 3 on the operation screen 24 is 165.8 and the width M of the character string is 125, the ratio is 1.3. Thus, a wavy decoration type with a short wavelength is determined. More specifically, for example, in the case of FIG. 16, the length L of the drawn line 13 is 129.1, the width M of the character string is 85, the ratio is 1.5, and the wavy line-shaped decoration with a short wavelength. The type will be determined. The decoration display unit 9 receives the decoration range and the decoration type from the decoration determination unit 6 and displays the decoration line 20 on the operation screen 25.

  Next, the processing flow of the character decoration system 1 will be described with reference to FIG. In addition, description about the same part as the said embodiment is abbreviate | omitted. In step 16 (S16), the decoration character specifying means 6b receives the position information and the character area information specifying the drawn line, specifies the target character from these, and the decoration determination means 6 sets the target character in the decoration range. And the width M of the character string of the target character is calculated. Also, the length L of the drawn line is calculated from the position information for specifying the drawn line, and the width M and the length L of the character string are compared (S17). In step 18 (S18), the decoration type determination means 6A determines the decoration type from the comparison result. The decoration display means 9 receives the decoration range and decoration type from the decoration determination means 6 and displays the decoration line in the decoration range (S19).

  As described above, when the length L is smaller than the width M as a result of the comparison between the length L of the drawn line and the width M of the character string, the linear distance is the width of the character to be decorated. It is determined that there is a high possibility that the drawn line is a straight line, and the decoration type is determined so that the decorative line is displayed in a straight line. On the other hand, if the length L is longer than the width M of the character string, it is determined that the drawn line is likely to be wavy, and the decoration type is determined so that the decoration line is displayed in the wavy line. The Therefore, the user's intention can be determined based on the relationship between the entire drawn line and the width of the character string to be decorated, and the decoration line can be displayed. Moreover, since it is judged by the whole drawn line, it is not necessary to draw a line accurately, and the operability is excellent. Furthermore, the decoration range and decoration type can be determined by one operation of drawing a line, and the operability is excellent.

  Other configurations and modifications are basically the same as those in the above-described embodiment, and thus the description thereof is omitted.

  In the above embodiment, the line shape of the decoration line is determined based on the comparison result between the length L of the drawn line and the width M of the character string. However, the present invention is not limited to this, and the decoration line type and line are determined according to the comparison result. Decoration types such as width, position, color, and combinations thereof can be determined.

  Next, a fifth embodiment of the present invention will be described.

  In the present embodiment, the decoration type is determined based on the number of times the drawn line 13 has passed the lower limit 16c of the character description area 16a. In this case, it is determined whether or not each of the plurality of positions included in the locus line 13a is in the character description area 16a. If the next position after the position in the character description area 16a is not in the character description area 16a, Since it passes the lower limit 16c between the two positions and moves outside the character description area 16a, it means that it has passed the lower limit 16c once, and vice versa. This determination is continued, and the number of times that the lower limit 16c is passed is calculated. If the number of times is greater than or equal to a predetermined number, it is determined as a wavy line. For example, in the example of FIG. 4 described above, the number of passes through the lower limit 16c is four.

  In addition to the number of times the drawn line 13 has passed the lower limit 16c of the character description area 16a, a guide line can be provided in the character description area 16a, and the decoration type can be determined from the number of times the guide line has passed. For example, the guide line may be provided at the center of the upper limit 16d and the lower limit 16c of the character description area 16a, and the number of guide lines may be singular or plural.

  Thus, for example, if the number of times the drawn line has passed the lower limit is small, it is determined that the drawn line is unlikely to be wavy, and the decoration type is set so that the decoration line is displayed as a straight line. Determined. On the other hand, if the number of times the drawn line passes the lower limit is large, it is determined that the drawn line is likely to be wavy, and the decoration type is determined so that the decoration line is displayed as a wavy line. . Therefore, the user's intention can be determined based on the relationship between the entire drawn line and the width of the character string to be decorated, and the decoration line can be displayed. Moreover, since it is judged by the whole drawn line, it is not necessary to draw a line accurately, and the operability is excellent. In addition, it can change with the length of a guide line, for example, the line which pulled the threshold value of the minimum passage frequency. Furthermore, the decoration range and decoration type can be determined by one operation of drawing a line, and the operability is excellent.

  Other configurations and modifications are basically the same as those in the above-described embodiment, and thus the description thereof is omitted. In the above embodiment, the line shape such as a straight line or a wavy line is determined according to the number of passes at the lower limit, but is not limited thereto, and the color, line type, line width, etc. of the decorative line according to the number of passes such as the lower limit. The decoration type such as the position and the combination thereof can be determined.

  In the above-described embodiment, a known method such as pattern recognition of operation screen information is used for specifying characters. However, the present invention is not limited to this. For example, a non-white portion can be specified as a character. In this case, since the character can be specified by judging the color, the specifying method is easy. Moreover, in the said embodiment, although the character description area | region 16a was identified from the space | interval of the adjacent character 15, it is not limited to this. For example, as shown in FIG. 17, the color of a region W in a predetermined range is detected from the line 13 drawn, and in the region, the range A1 whose color is black is determined as the character description region, and the non-black range A2 is It is determined that it is not a character description area. For the range A1 in which the color is black, for example, it is determined whether the color of the region W is black from the left side to the right side in the x-axis direction (the horizontal direction of the paper surface). The range up to the position P2 determined to be black is set as a black range A1, and the range from the previous position P2 to the position P3 determined as black is added to the black range A1. By repeating this, positions P4,..., Pn,..., Pz determined to be black are detected, and a range A1 from the first position P1 determined to be black to the last position Pz is specified as a character description area. .

  Further, in the above embodiment, the character area information acquisition unit 8 acquires the character area information based on the operation screen information acquired from the operation screen information acquisition unit 7, but the present invention is not limited to this. The character area information of the operation screen can be acquired from the attached information. Further, in the above-described embodiment, the operation information acquisition unit 4 transmits information indicating that a line has been drawn to the operation screen information acquisition unit 7, and the operation screen information acquisition unit 7 receives this and receives the operation of the display unit 10. Although the operation screen information of the image displayed on the entire screen is acquired, the present invention is not limited to this. For example, instead of the operation information acquisition unit 4, the position information acquisition unit 5 transmits position information specifying the drawn line to the operation screen information acquisition unit 7, and the operation screen information acquisition unit 7 receives the position information and receives the position information. It is also possible to specify the position of the operation screen corresponding to the line drawn from and to obtain the operation screen information of the image displayed on a part of the operation screen including this position. In the above embodiment, the character description area is written horizontally, but the same applies to the case where the character description area is written vertically.

  Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and can of course be implemented in various forms without departing from the gist of the present invention. It is of course possible to determine the decoration type by combining the decoration type determination by the decoration determination means 6 in all the embodiments described above. Thereby, a plurality of decoration types can be determined by one operation process or determination result. For example, when the decoration type is determined by combining the line ratio, the number of times the drawn line has passed the lower limit, and the comparison result (L / S) between the length L of the drawn line and the straight line distance S, the ratio Is used to determine the decoration type such as the position, and the decoration type such as the line shape is determined from the number of passes. When the line shape is determined to be a wavy line, the wave number and amplitude of the wavy line are determined from the comparison result (L / S). As a result, a plurality of decoration types can be determined simultaneously with a line drawn once. In addition, since the user can intuitively recognize the ratio and position, the number of passages and the line shape, the comparison result (L / S) and the wave number, etc., the decorative line can be displayed according to the user's intention and the operation can be performed. Excellent in properties.

  In the above-described embodiment, the character decoration system 1 and the character decoration program 2 are provided with the above-described units, the pointing device 3, the display unit 10 and the like in one computer, but are configured by a plurality of computers. May be. For example, a single or a plurality of client computers and a server computer are configured to be communicable via a network, and the server computer has operation information acquisition means, position information acquisition means, operation screen information acquisition means, character area information acquisition means, decoration determination The position information acquisition means is a server based on the operation information of the pointing device of the client computer acquired by the operation information acquisition means and the operation screen information of the display unit acquired by the operation screen information acquisition means. The position information may be acquired by a computer, the character area information may be acquired by a character area information acquisition unit, and the decoration type may be determined by a decoration determination unit.
