The keyboard 204 and the pointing device 205 are included in the input unit 103 in FIG.

  The CPU 206 controls each unit connected via the bus 212 based on a control program stored in the ROM 207 or the RAM 1208. The ROM 207 holds various control programs (BIOS), various data, and the like. The RAM 208 loads a program installed in the storage device (HDD) 209 or the external storage device 203 at the time of execution, and executes it under the control of the CPU 206. The RAM 208 has a work area at the time of processing by the CPU 206, a data save area at the time of error processing, a control program load area, and the like.

It can also be done from.

  The correspondence between FIG. 1 and FIG. 2 will be briefly described. The information holding unit 105 corresponds to, for example, the HDD 209 or the CDD 203, and each function unit indicated by the enhancement calculation unit 102, the information extraction unit 104, and 106-110. Is achieved by a control program with the CPU 206. Further, the display unit 101 and the input unit 103 correspond to the display unit 201, the keyboard 204, and the PD 205, respectively.

  Next, a processing procedure according to the embodiment of the present invention will be described with reference to a flowchart. Note that this flowchart shows an example of the present embodiment, and considering the processing speed, memory consumption, or processing language implementation system, without changing the spirit of the flowchart of the present embodiment, Needless to say, the present invention can be implemented by other forms of flowcharts.

  3 to 6 are flowcharts for explaining difference information highlighting processing in the information processing apparatus according to the present embodiment. A program for executing this processing is previously stored in the storage device 209 from the FDD 210, the CDD 203, the interface 211, and the like. It is installed, loaded into the RAM 208 at the time of execution, and executed under the control of the CPU 206. Note that flags, various variables, data, and the like referred to in this flowchart are stored in the work area of the RAM 208, and FIG. 12 shows a memory map of the RAM 208 that stores these flags, variables, and the like. Yes.

  This process is started by performing a predetermined start operation. First, in step S301, the first information to be displayed as a list, which is extracted from the information holding unit 105 by the information extracting unit 104, is received. Note that a file name is taken as an example of information consisting of character strings in the present embodiment. Next, in step S302, the presence / absence of the information received in step S301 is determined. If there is no information (file name), this process ends. If there is information, the process proceeds to step S303, and the first information is displayed on the display unit 101. In step S304, the first information is stored as reference information in the reference information file 391 (FIG. 12). This reference information file is stored in the RAM 208, for example.

  In step S306, the next information extracted from the information holding unit 105 by the information extracting unit 104 is received and stored in the comparison target information 315 (FIG. 12) in the RAM 208. Next, in step S307, the presence / absence of the information received in step S306 is determined. If there is no information, this process is terminated. In step S307, if there is the next information, the process proceeds to step S308, and the reference information setting flag 301 for determining whether or not the reference information may be reset is turned off (no reference information is set). The reference information setting flag 301 is provided in the work area of the RAM 208.

  Next, in step S309, the number of characters of the comparison target information 315 received in step S306 is compared with the reference character number 302 stored in advance in the RAM 208. If the number is less than the reference character number, the process proceeds to step S310 and received in step S306. The comparison target information 315 is displayed as it is (without highlighting), and the process returns to step S306. The reference character number 302 is specified by the reference character number specifying unit 107 described above and stored in the RAM 208 in advance. Here, the reference character number may be a predetermined number, or may be specially designated by the user or the system.

  On the other hand, if it is determined in step S309 that both the number of characters of the comparison target information 315 and the character string of the reference information determined in step S304 are greater than or equal to the reference character number, or no reference character number is designated, the process proceeds to step S311 and stored in step S304. The obtained reference information 391 and the comparison target information 315 are compared to obtain a portion to be emphasized (a different portion). Details of step S311 will be described in detail with reference to FIG.

  In step S312, if the comparison target information 315 is different from the reference information 391 and there is a portion to be highlighted, that portion is highlighted. If there is no part to be emphasized (difference), the comparison target information 315 received in step S306 is displayed as it is. In step S313, it is determined whether the reference information setting flag 301 is on or off. If it is off (no reference information is set), the process returns to step S306. Here, when the reference information 391 is fixed, the reference information setting flag 301 remains off because the setting of the reference information 391 is not changed. On the other hand, when the reference information 391 is changed, the reference information setting flag 301 is set to ON. If the reference information setting flag 301 is ON (reference information is set) in step S313, the process proceeds to step S314, and the reference information 391 is the information on the top (first line) of the list information or the most recent ( For example, as shown in FIG. 10, if the top (first line) is the reference information 391, or if the reference information 391 is not specified, the process returns to step S306. On the other hand, as shown in FIG. 9, for example, when the latest information is used as the reference information, the process proceeds to step S315, the reference information 391 is updated with the comparison target information 315 received in step S306, and the process returns to step S306.

  FIG. 4 is a flowchart for explaining the details of the process for obtaining the emphasized part (difference part) in step S311 of FIG. 3, in which the reference information 391 and the comparison target information 315 are compared to obtain the emphasized part. It is.

  First, in step S400, all the difference character position information 392 is cleared (all are assumed to be no difference). The difference character position information 392 stores character position information that is different between the compared information, and the difference character position information 392 is stored in the RAM 208.

  FIG. 7 is a diagram for explaining the difference character position information 392.

  In the figure, “1” to “5” indicate character positions, respectively, and 701 is an area for storing information indicating whether or not the first information of the received information is different from the reference information. Similarly, reference numeral 702 denotes an area for storing information indicating whether the second character information of the received information is different from the reference information. Similarly, the storage area is equivalent to the number of characters of the comparison target information 315 (information to be compared with the reference information). In the example of FIG. 7, a storage area for five characters is shown, but it goes without saying that the number of storage areas is variable according to the number of characters in the comparison target information 315. In FIG. 7, “present” is stored in areas 703 and 705 as indicated by 709 and 710. This shows that the third and fifth characters from the beginning of the received information are different from the reference information.

  In FIG. 4 again, in step S401 after step S400, the number of characters in the reference information 391 and the number of characters in the comparison target information 315 are compared. If the number of characters is different from each other, the process proceeds to step S404. , The reference information 391 and the comparison target information 315 are compared character by character from the beginning, and if a different character is found, the character position is stored in the difference character position information 392. Next, in step S403, the ratio of the number of characters that matches the reference information 391 (same character ratio) is calculated with respect to the total number of characters in the comparison target information 315. Next, in step S409, the obtained same character ratio and The reference rate 303 specified by the reference rate specifying unit 108 is compared. The reference rate 303 may be a number specified in advance by the reference rate specifying unit 108, or may be arbitrarily set by a user or a system. Here, if the same character ratio is not greater than the reference rate 303, the process proceeds to step S410, and the portion of the comparison target information 315 that is different from the reference information 391 is not highlighted.

  This is because, when the number of characters that differ by a certain amount or more is included with respect to the total number of characters in the comparison target information 315, it is determined that it is not meaningful to highlight the different characters. It is.

  On the other hand, if it is determined in step S409 that the same character ratio is equal to or smaller than the reference rate 303, or if the reference rate 303 is not designated, the process proceeds to step S411, and the difference character position information 392 is used for comparison. In the target information 315, the position of a different character is set as an emphasized portion. Next, in step S412, the reference information setting flag 301 is turned on (reference information is set), the process goes out of step S311 and the process proceeds to step S312. .

  On the other hand, if the number of characters in the reference information 391 and the number of characters in the comparison target information 315 are different from each other in step S401, the process proceeds to step S404 to determine which character position included in the information is compared. This is designated by the comparison condition designating unit 109 described above and stored in the RAM 208 as the comparison condition 304. This comparison condition 304 specifies whether the comparison is performed from the front of the character string, from the rear, or from the front and the back of the portion with the most same part when the number of characters in the comparison target character string is different. It is.

  In step S404, it is determined whether or not comparison is set from the first character. When comparing from the first character, the process proceeds to step S402, and the above-described processing is performed. If it is determined in step S404 that the comparison is not from the first character, the process proceeds to step S405, where it is determined whether the comparison condition 304 is set to compare from the last character. If the comparison from the last character is set, the process proceeds to step S407, where the reference information 391 and the comparison target information 315 are compared one by one from the last character, and the positions of the different characters are compared with the difference character position information 392. And proceed to step S403.

  On the other hand, if it is not a comparison from the last character in step S405, the process proceeds to step S413, and the parts before and after the most matched part are compared. Here, a character string portion in which the same number of the same characters are consecutively arranged is extracted from the reference information 391 and the comparison target information 315, and before and after that, the positions of different characters are obtained to obtain the difference character positions. Store in information 392. In step S403, the above-described processing is performed. Details of step S413 will be described in detail with reference to FIG.

  FIG. 5 is a flowchart for explaining details of the processing in step S413 of FIG. 4 according to the present embodiment. Here, the reference information 391 and the comparison target information 315 extract the portion where the same characters are continuously arranged most frequently, compare the front and back of the character strings, and store the positions of the characters with differences.

  First, in step S 501, “0” is set in the “maximum equal number of characters” 305 provided in the RAM 208. Next, in step S502, “1” is set to the counter N306 indicating the number of characters of the reference information 391. Next, in step S503, “1” is set to the counter M307 indicating the number of characters of the comparison target information 315. Set. In step S504, “0” is set in the “equal number of characters” 308 in the RAM 208. In step S505, the Nth character of the reference information 391 indicated by the counter N306 is compared with the Mth character indicated by the counter M307 of the comparison target information 315 to determine whether they are equal. If they are not equal, the process proceeds to step S506. If they are equal, the process proceeds to step S510. In step S506, 1 is added to the counter M307. In step S507, the value of the counter M307 is compared with the number of characters (B-MAX) in the comparison target information 315. If the number of characters of the comparison target information 315 is equal to or smaller than the counter M, the process proceeds to step S508, and 1 is added to the character counter N306 of the reference information 391. In step S509, the counter N307 is compared with the number of characters (A-MAX) in the reference information 391. On the other hand, when the value of the counter M307 is larger than the number of characters in the comparison target information 315 in step S507, the process returns to step S505.

  If it is determined in step S509 that the number of characters (A-MAX) in the reference information 391 is equal to or smaller than the value of the counter N306, the process returns to step S503 to perform the above-described processing. On the other hand, when the value of the counter N306 is larger than the number of characters (A-MAX) of the reference information 391, the process proceeds to step S523, where it is determined whether the “maximum equal number of characters” 305 is “0”. Since there is no equal character string between the comparison target information 315 and the reference information 391, the detailed procedure of step S413 is skipped without being stored in the difference character position information 392, and the process proceeds to step S403 of FIG. On the other hand, if the “maximum equal number of characters” 305 is not “0” in step S523, the process proceeds to step S525, and the position information of the difference before and after the character string in which the same characters are arranged in succession is displayed as the difference character position information 392. Remember. Details of step S525 will be described in detail with reference to FIG. In step S526, the reference information setting flag 301 is turned on (reference information is set), the process of step S413 is exited, and the process proceeds to step S403 in FIG.

  On the other hand, in step S505, the Nth character indicated by the counter N306 of the reference information 391 is compared with the Mth character indicated by the counter M307 of the comparison target information 315. The value of the counter N 306 indicating what number character of the reference information is set in the “position N” 309. In step S 511, the value of the counter M 307 indicating the number of characters of the received information is set in “start position M” 310. In step S512, 1 is added to the “equal number of characters” 308.

  Next, in step S513, “equal number of characters” 308 and “maximum equal number of characters” 305 are compared. If the value of “equal number of characters” 308 is greater than “maximum equal number of characters” 305, the process proceeds to step S514. On the other hand, if “equal number of characters” 308 is equal to or smaller than “maximum equal number of characters” 305 in step S513, the process proceeds to step S517. In step S514, the “maximum equal number of characters” 305 is set to a value of “equal number of characters” 308. Next, in step S515, the “maximum start position N” 311 is set to the value of “start position N” 309. In step S515, the value of “start position M” 310 is set in “maximum start position M” 312, and the flow advances to step S517 to add 1 to the reference information counter N306. In step S518, the character counter N306 of the reference information is compared with the number of characters (A-MAX) of the reference information 391. Here, when the value of the counter N306 is larger than the number of characters (A-MAX) of the reference information 391, the process proceeds to step S523, and the above-described processing is executed, but the value of the counter N306 is the number of characters (A-MAX) of the reference information 391. ) Or smaller than that, the process proceeds to step S519, and 1 is added to the counter M307. In step S520, the value of the counter M307 is compared with the number of characters (B-MAX) of the comparison target information 315. If the value of the counter M307 is larger than the number of characters of the comparison target information 315, the process returns to step S503 and the above processing is performed. If the number of characters (B-MAX) of the comparison target information 315 is equal to or smaller than the value of the counter M307, the process proceeds to step S521, where the Nth reference information 391 indicated by the counter N306 is designated. And the Mth character of the comparison target information 315 indicated by the counter M307. If they are not equal, the process proceeds to step S522, the value of “start position N” 309 is set in the counter N306, the process returns to step S504, and the above-described processing is performed. On the other hand, if the characters are equal in step S521, the process returns to step S512 and the above-described processing is performed.

  FIG. 6 is a flowchart showing details of the process of step S525 of FIG. 5 according to the present embodiment. Here, the position information of different characters before and after the character string in which the same number of the same characters are continuously arranged. Shows a procedure for storing.

  First, in step S601, the value of “maximum start position N” 311 is set in the counter P313 indicating the number of characters of the reference information 391. In step S 602, the value of “maximum start position M” 312 is set in the counter Q 314 indicating the number of characters in the comparison target information 315. In step S603, 1 is subtracted from the counter P313. Subsequently, in step S604, 1 is subtracted from the counter Q314. In step S605, it is determined whether the value of the counter Q314 is 1 or more. If the value of the counter Q314 is 1 or more, the process proceeds to step S606. If the value of the counter Q314 is less than 1, the process proceeds to step S610. In step S606, it is determined whether the value of the counter P313 is 1 or more. If the value of the counter P313 is 1 or more, the process proceeds to step S608. If the value of the counter P313 is less than 1, the process proceeds to step S607, and the difference “position” is set to the Qth of the difference character position information 392, and the process returns to step S604. The above-described processing is performed. In step S608, the Pth character indicated by the value of the counter P313 of the reference information 391 is compared with the Qth character indicated by the counter Q of the comparison target information 315. If they are not equal, the process proceeds to step S609. Then, the difference “present” is set to the Qth of the difference character position information 392, the process returns to step S603, and the above-described processing is executed. On the other hand, if it is determined in step S608 that they are equal, the process returns to step S603 and the above-described processing is performed.

  On the other hand, if the value of the counter Q314 is less than 1 in step S605, the process proceeds to step S610, where {("maximum start position N") + ("maximum number of equal characters" -1} is set in the counter P313. In step S611, a value of {("maximum start position M") + ("maximum number of equal characters" -1)} is set to the value of the counter Q314.Next, in step S612, 1 is added to the counter P313, In step S613, 1 is added to the counter Q314, and in step S614, the value of the received information counter Q314 is compared with the number of characters (B-MAX) of the comparison target information 315. Here, the comparison is performed. When the number of characters of the target information 315 is equal to or smaller than the value of the counter Q314, the process proceeds to step S615. Ri counter when Q is large, the process proceeds to step S526 of omission Figure 5 a description procedure of step S525.

  When the number of characters of the comparison target information 315 is equal to or smaller than the value of the counter Q314, the value of the counter P313 of the reference information 391 is compared with the number of characters (A-MAX) of the reference information 391 in step S615. . If the number of characters in the reference information 391 is equal to or smaller than the value of the counter P313, the process proceeds to step S617. On the other hand, if the value of the counter P313 is larger than the number of characters in the reference information 391 in step S615, the process proceeds to step S616, and the Qth difference indicated by the value of the counter Q314 in the difference character position information 392 is set to “present”. Returning to step S612, the above-described processing is performed.

  In step S617, the Pth character indicated by the value of the counter P313 in the reference information 391 is compared with the Qth character indicated by the counter Q314 in the comparison target information 315.

<Specific example of displaying a list of highlighted file names>
Next, a specific example of file name list display according to the embodiment of the present invention will be described.

  FIG. 8 is a diagram showing an example of a file name list display in which the difference information according to the present embodiment is not expressed with emphasis.

  In FIG. 8, reference numerals 801 to 808 denote display examples of information (character strings) in the first to eighth lines. Here, the number of characters of information displayed on each line is 26 characters, and similar information is displayed without being highlighted. Therefore, in such a display, it is difficult to recognize the difference in the character string of each displayed line.

  9 to 11 are diagrams illustrating examples of highlighting difference information in the file name list display in the information processing apparatus according to the present embodiment.

  FIG. 9 is a diagram illustrating an example of a list display in which different information is highlighted. The contents of the displayed list information are exactly the same as in FIG. The reference information position in this case is the line immediately above each line being displayed in the list, and the information in the line immediately above that line is the reference information. That is, the emphasized portion of the second line 902 is determined based on a comparison between the first line 901 and the second line 902. Similarly, the emphasized part of the third line 903 is determined based on the comparison between the second line 902 and the third line 903, and the emphasized part of the fourth line 904 is determined between the third line 903 and the fourth line 904. It is determined based on comparison. Hereinafter, similarly, the emphasized portion of the eighth line 908 is determined based on the comparison between the seventh line 907 and the eighth line 908.

  Here, since the number of characters in all lines is 26 characters, the designation of the comparison condition does not affect how to obtain the emphasized portion. In addition, the reference number of characters is not specified here because it is a target unless otherwise specified. Similarly, the reference rate is not specified here because it is all targeted when not specified. The highlighting method here is bold, and the background color is black and the character color is white (reverse display).

  The second line 902 is compared with the character string 901 of the latest first line. Here, the 15th to 17th characters (“902”) are different from the character string of the first line. Accordingly, the 15th to 17th characters (“902”) on the second line are highlighted with bold font, black background color, and white character color.

  The third line 903 is compared with the character string 902 in the second line immediately above, where only the 22nd character (“2”) is different. Therefore, the 22nd character ("2") is highlighted with bold font, black background color, and white character color.

  Similarly, since the fourth line 904 is different from the third line 903 only in the 22nd character ("3"), the 22nd character ("3") is bold and the background color. Is highlighted with black and text color white. Similarly, in the fifth line 905, the sixth line 906, the seventh line 907, and the eighth line 908, only the different characters are highlighted as compared with the character string of the most recent line.

  FIG. 10 is a diagram showing an example of highlighting according to the present embodiment, and the display content is exactly the same as in the case of FIG. 8 described above. In the example of FIG. 10, the reference information position is the top line in the list, and the information on the first line is the reference information.

  Accordingly, the emphasized portions of the second row 1002 to the eighth row 1008 are all determined by comparison with the first row 1001. Here, since the number of characters in all lines is the same as 26 characters, the designation of the comparison condition does not affect the determination of the emphasized portion. In addition, the reference number of characters is not specified here because it is a target unless otherwise specified. Similarly, the reference rate is not specified here because it is all targeted if not specified. Further, the emphasis expression method is bold and italic is designated.

  As a result of comparing the second line 1002 with the information 1001 in the first line on the top, the 15th to 17th characters are different, so these 15th to 17th character strings ("902") are bolded. And highlighted in italics.

  Similarly, the character strings on the third line 1003 to the eighth line are respectively compared with the information 1001 on the first line, and different characters are highlighted in bold and italic.

  FIG. 11 is a diagram showing an example of file name emphasis display according to the present embodiment. Here, the reference information position is at the top of the list, that is, the first line, and the information on the first line is the reference information. It has become.

  That is, the emphasized part of the second line 1102 is determined by comparison with the first line 1101, and the emphasized part of the third line 1103 is also determined by comparison with the first line 1101. Similarly, the emphasized portions of the 4th to 8th rows are determined based on the comparison with the information 1101 on the 1st row. Here, the comparison condition is not particularly specified, so the comparison before and after the most matched part is performed. Here, the reference number of characters is 20 characters. Accordingly, information less than 20 characters is not highlighted (indicated by 1103) even if different characters exist. Here, the reference rate is designated as 50%. Thus, information that matches less than 50% is not highlighted (indicated by 1106). Further, the highlighting method is bold and underlined (underlined) is designated.

  Since the second line 1102 is different from the information 1101 in the first line on the first line, the 15th to 17th characters are different, so the 15th to 17th characters ("902") are bold, and Underlined and highlighted. The third line 1103 is not highlighted because the number of characters is “11”, which is less than the reference number “20” here.

  Next, as a result of comparison with the information 1101 on the first line, the fourth line 1104 is different from the seventh, eighth, and 15th to 17th characters, so these characters are highlighted in bold and underlined. ing. Next, as a result of comparison with the information 1101 on the first line, the fifth line 1105 is different from the fifth, fifteenth and seventeenth characters, so these characters are highlighted in bold and underlined. Next, as a result of comparison with the first line 1101, the sixth line 1106 is different in the 3rd to 5th, 7th, 8th, 14th to 17th, 19th to 22nd characters, that is, 13 characters in total. This is half of the 26 characters and is not highlighted because the reference rate is less than 50%. Furthermore, in the 7th line 1107, compared to the information 1101 in the 1st line, the number of characters in the 1st line is 26 characters, whereas the number of characters in the 7th line 1107 is 27 characters. It becomes a comparison. Here, since the difference before and after the same number of the same number is continuously compared, the information from the first to the 14th character (“CCABC-SN-20040”) of the information 1101 on the first line and the information on the seventh line The second character to the fifteenth character 1107 (“CCABC-SN-20040”) match most continuously. Therefore, by comparing the difference before and after, the 1st to 16th characters (“#” and “902”) of the information 1107 on the seventh line are different. , 16-18th characters ("#" "902") are underlined and highlighted.
