Further, since the decoration type is determined based on the whole line drawn by the pointing device, it is possible to display the decoration line according to the intention of the user operation.

  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. 4, 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. An acquisition unit 5, a decoration determination unit 6 that determines the decoration type of the character based on the position information acquired by the position information acquisition unit 5, and a decoration line of the character according to the decoration type determined by the decoration determination unit 6 A decoration display means 9 for displaying on the operation screen of the unit 10 is provided. 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, and performs a calculation according to a program. The computer C may be composed of, for example, one or a plurality of terminals. -You may be comprised with the server and client terminal in a client system. Each means may be realized by hardware or software.

  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 a cursor 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, and the acquired operation information is transmitted to the position information acquisition means 5. 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, the locus line 13a is a locus of the cursor moved from the start to the end of the position specifying operation of the pointing device 3 as shown in FIG. 1A, and the virtual line 13b is a pointing as shown in FIG. This is a line connecting the start position 14a and the end position 14b designated by the device with a straight line.

  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 locus line 13a, the position information for specifying the locus line 13a is obtained, for example, by calculating an approximate expression from a set of coordinate information to which the cursor has moved, and the position coordinates representing the locus line 13a are obtained from this approximate expression. It is acquired 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 decoration determination means 6 receives position information specifying the line 13 drawn from the position information acquisition means 5 and determines the decoration type of the character. In this example, the decoration determination means 6 changes the decoration type determination means 6a. In addition, 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.

  Here, the length of the drawn line 13 is the length along the drawn line 13, and the straight line distance S is the length between the start position and the end position of the drawn line. The decoration type is a rule for converting the drawn line 13 into a decoration line. For example, a line shape such as a straight line or a wavy line, a line type such as a solid line or a wavy line, a position such as the center or underline of the line, Including 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, as shown in FIG. 1 (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. 1 (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 linear distance S is calculated from the coordinates of the start position 14a and the end position 14b included in the position information of the drawn line 13. In this case, as shown in FIG. 1C, the length L of the drawn line 13 is calculated as “129.1”, and the linear distance S is calculated as “80.0”.

  The decoration determining means 6 then calculates the ratio of the length L of the drawn line 13 to the straight distance S (L / S), and the difference obtained by subtracting the straight distance S from the length L of the drawn line 13 (LS). ) And the straight line distance S are compared. In the case of FIG. 1B, as shown in FIG. 1C, 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”.

  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. For example, as shown in FIG. 5, 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 of the line 13 drawn from the straight line distance S. The ratio (L / S) is used as a threshold when L is 1.5 times longer. If the ratio is less than 1.2, the decoration type of the straight line type is set, and if the ratio is 1.2 or more and less than 1.5, the decoration type of the long wave line type is set, and the ratio is 1 If it is 0.5 or more, the decoration type of the line type of the wavy line having a wavelength shorter than the wavelength when the ratio is 1.2 or more and less than 1.5 is set.

  For example, as shown in FIG. 7B, 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 linear decoration type is determined. Further, as shown in FIG. 7C, when the length L of the drawn line 13 is 117.3 and the straight line distance S is 85, the ratio is 1.38, and the wavy line-shaped decoration type having a long wavelength is determined. It is done. Further, as shown in FIG. 7D, 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 wavy line-shaped decoration type having a short wavelength is determined. It is done. In the case of FIG. 1, the ratio (L / S) is 1.6 as described above, and the wavy line-shaped decoration type having a short wavelength is determined. 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.

  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. 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 and y-coordinate of the start position of the drawn line 13 and the x-coordinate and y-coordinate of the end position, the decoration line determined by the decoration type is set to the start position and the end. Displays the position. 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), monitors whether or not a line is drawn with the pointing device 3 from the operation content of the operation information, and detects that the line is drawn with the pointing device 3. When this is done (S2), the operation information relating to the drawn line 13 is transmitted to the position information acquisition means 5.

  The position information acquisition means 5 acquires the operation information related to the drawn line 13, specifies the start position 14a and the end position 14b from the operation information, and expresses an expression representing the line drawn from the coordinate information of the operation information. It is calculated and acquired as position information for specifying the line 13 from which the position coordinates are drawn (S3). 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 length L of the line 13 drawn from the position information, and calculates the linear distance S from the position information of the start position 14a and the end position 14b of the drawn line 13. (S4) The length L of the drawn line 13 is compared with the linear distance S (S5). Then, the decoration type determination means 6a determines the decoration type based on the comparison result (S6). Further, the decoration determination means 6 determines the decoration range from the position information (S7). Then, the decoration display means 9 receives the decoration range and the decoration type, and displays the decoration line in the decoration range of the operation screen (S8).

  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.

  In FIG. 7, the line shape of the decoration line such as a straight line or a wavy line is determined based on the ratio of 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 second 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 position information for identifying the line 13 drawn from the position information acquisition means 5 and date / time information of the start position and end position, calculates an operation speed from the position information and date / time information, and calculates the operation speed. The character decoration type is determined based on the above. 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. 1A 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 between adjacent position points as shown in FIG. It is also possible to calculate “5.50” by calculating the time difference between the two.

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

  For example, a dark color is set when the operation speed is equal to or higher than the threshold 20, and a light color is set when the operation speed is less than the threshold 20. In this case, when the operation speed is 23.5 as in the example of FIG. 6, as shown in FIG. 8A, the light marker display 26a is determined. Further, as shown in FIG. 8B, when the operation speed is 17.9, the dark marker display 26b at the 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, and 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. 8, the position corresponding to the decoration range is displayed by the light marker display 26a and the 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 3 (S3) in FIG. 6, the position information acquisition means 5 acquires the operation information related to the drawn line 13, and specifies the start position 14a and the end position 14b from the operation information. And the position information which specifies the line drawn from the coordinate information of the operation information is acquired, and these date / time information is obtained from the operation information of the start position 14a and the end position 14b, and these are given to the decoration determination means 6. Send. The decoration determination unit 6 calculates the operation time T from the date and time information of the start position and the end position, and calculates the length L of the line 13 drawn from the position information (S4). In step 5 (S5), the operation speed (L / T) is calculated from the length L of the drawn line 13 and the operation time T (S5). Furthermore, in step 6 (S6), the decoration determination means 6 determines the decoration type based on the operation speed (L / T) (S6). Further, the decoration determination means 6 determines the decoration range from the position information specifying the drawn line (S7). And the decoration display means 9 receives a decoration range and a decoration classification, and displays a decoration line in a decoration range (S8).

  Thus, 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 fast.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. .

  Next, a third 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 guide line. The guide line is, for example, a straight line connecting the start position and end position of the drawn line 13, a lower limit 16c of a character description area 16a described later, a center of an upper limit 16d and a lower limit 16c of the character description area 16a, and a combination thereof. is there.

  When a straight line connecting the start position and the end position of the drawn line 13 is provided as a guide line, the decoration determination unit 6 uses the start position and the end position among the position information obtained from the position information acquisition unit 5. Find the equation of the straight line connecting The y-coordinate of the corresponding straight line is calculated from the x-coordinate of the position coordinate of the position information using this straight line formula, and the y-coordinate of the straight line is compared with the y-coordinate of the position coordinate, and the position coordinate is located above the straight line. Or whether it is located below. The same applies to the next position coordinates. If the next position coordinate is below when the previous position coordinate is above the straight line, it is determined that the drawn line 13 has passed the guide line. The opposite is also true. This determination is continued, and the number of times that the drawn line 13 passes the guide line is calculated. If the number of times is equal to or greater than a predetermined number, the decoration type to be a wavy line is determined, while if it is less than the predetermined number, the decoration type to be a straight line is determined. In the example of FIG. 1A, the number of times of passing through the guide line is three.

  Thus, for example, if the number of times the drawn line has passed the guide line is small, it is determined that the possibility that the drawn line is wavy is low, and the decoration type is displayed so that the decoration line is displayed as a straight line. Is determined. On the other hand, if the drawn line passes the guide line many times, it is determined that the drawn line is likely to be wavy, and the decoration type is determined so that the decorated line is displayed as a broken line. The For this reason, it is not necessary to draw a line accurately and it is excellent in operativity by judging with the whole drawn line. 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 and a wavy line is determined according to the number of passes of the guide line, but is not limited thereto, and the color, line type, line width, etc. of the decoration 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 each of the above embodiments, the decoration range is obtained from the position information of the drawn line, and the drawn line itself or between the start position and the end position is determined as the decoration range. However, the decoration range is determined from the character area information and the position information. The target character of the character may be specified, and the target character may be used as the 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. 9, the character decoration system 1 includes an operation screen information acquisition unit 7 that acquires information on the operation screen displayed on the display unit 10, and a part or all of the area of the operation screen. Character area information acquisition means 8 for acquiring character area information from the operation screen information is further provided. The decoration determination unit 6 includes a decoration type determination unit 6a and a decoration character identification unit 6b. The decoration type determination unit 6a determines the decoration type, and the decoration character identification unit 6b specifies a character decoration target character. Further, when the operation information acquisition unit 4 detects that the final processing indicating that the line has been drawn is included in the operation content, the operation information acquisition unit 4 transmits the operation information related to the drawn line to the position information acquisition unit 5. The fact that it has been detected is transmitted to the operation screen information acquisition means 7.

  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. 3, 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.

  Further, the decoration character specifying means 6b 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 character decoration target character therefrom. The target character is specified and sent to the decoration display means 9 as a decoration range. That is, the x-coordinate of the start position 14a and the x-coordinate of the end position 14b are acquired from the position information specifying the drawn line 13, and the space between these is set as a 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 each character included in the character area information, and 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. 11 (a), the decoration target is 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. As the area, the left end position and the x coordinate of the right end position of the display positions of “A”, “I”, “U”, “E”, “O”, and “KA” included in the character area information are compared. 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. Note that the y coordinate of the decoration range is predetermined or arbitrarily determined. For example, in the entire range of the decoration range, the y coordinate of the start position, the y coordinate of the end position, and the y coordinate between the start position and the end position can be used. It can also be between the character description area of the target character, that is, between the upper limit and lower limit of the character description area, and if it is set as underline in the decoration type, it can be the lower limit position of the character description area it can.

  Further, the decoration display means 9 receives the decoration type and the decoration range from the decoration determination means 6 and displays the decoration line 17 over the width M of the target character that is the decoration object. For example, in the case of FIG. 11 (a), the character description area 16a in the entire range of “A” to “O” specified as the target character is displayed with the shading marker display 26 of the decoration type determined based on the operation speed. indicate. 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, when the operation speed when the line 13 is drawn as shown in FIG. 11A is 23.5, the light marker display 17b is determined as shown in FIG. 11B, and the width of the target character is determined. It is displayed on the operation screen 25b over M. When the operation speed is 17.9, as shown in FIG. 11C, the dark marker display 17c is determined and displayed on the operation screen 25c over the width M of the target character.

  Next, the flow of processing of the character decoration system 1 will be described with reference to FIG. Step 11 (S11), Step 12 (S12) and Step 15 (S15) are the same as Step 1 (S1), Step 2 (S2) and Step 3 (S3) in FIG. 6 of the above embodiment. Since there is, description is abbreviate | omitted.

  In step 12 (S12), when the operation information acquisition means 4 detects that a line has been drawn by the pointing device 3, the operation information related to the drawn line 13 is transmitted to the position information acquisition means 5, and the operation screen information The fact that it has been detected is transmitted to the acquisition means 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 (S13). 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 (S14). That is, as shown in FIG. 3, 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.

  Next, the decoration character specifying means 6b receives the position information and the character area information specifying the drawn line, specifies the target character from them, and the decoration determination means 6 determines this target character as the decoration range ( S16). Then, the decoration determination unit 6 calculates an operation time T from the start position to the end position when the pointing device 3 is drawn based on the date and time information of the start position and the end position acquired by the position information acquisition unit 5. In addition to the calculation, the length L of the line 13 drawn from the position information is calculated (S17), and the operation speed (L / T) is calculated (S18). Furthermore, the decoration type determination means 6a defines the operation speed (L / T) and the decoration type and determines the decoration type from the operation speed based on a predetermined standard (S19). 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 of the operation screen (S20).

  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.

  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. 12, the color of a predetermined area W is detected from a line 13 drawn, and the area A1 in which the color is black is determined as a character description area, and the non-black area 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. .

  In the above embodiment, the character area information acquisition means 8 has acquired the character area information based on the operation screen information acquired from the operation screen information acquisition means 7, but the present invention is not limited to this. The character area information of the operation screen can be acquired from the 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.
