  Next, the operation of the electronic dictionary device 10 having the above configuration will be described.

  Here, a description will be given mainly of a dictionary search process from characters recognized by handwriting input.

  FIG. 4 is a flowchart showing the handwritten dictionary search process of the first embodiment in the electronic dictionary device 10.

  FIG. 5 is a flowchart showing a batch correction process associated with the handwritten dictionary search process of the first embodiment of the electronic dictionary device 10.

  FIG. 6 is a diagram illustrating the operation of the handwriting input unit 16 associated with the handwriting dictionary search process of the first embodiment of the electronic dictionary device 10.

  In the dictionary search processing mode, the handwriting input unit 16 has, as shown in FIG. 6, for example, handwritten character input areas m1 and m2 for inputting characters one by one by hand, and the handwritten character input areas m1 and m2. A recognized character display area n in which the first candidate characters input by handwriting and recognized are displayed in sequence, and a scroll for scrolling and displaying the recognized character string displayed in the recognized character display area n. The buttons C1 and C2 function as a “rewrite” button D for erasing all characters displayed in the handwritten character input areas m1 and m2 and the recognized character display area n and instructing rewriting.

  When handwritten characters are input and displayed in the handwritten character input areas m1 and m2 of the handwriting input unit 16 to input a search character string (keyword) (step S1), the input and displayed handwritten characters are displayed. Character recognition is performed (step S2), the recognition candidate character is stored in the handwriting recognition conversion candidate memory 23b in the RAM 23, and the first candidate character is input and displayed in the recognized character display area n (step S3).

  At this time, the first candidate character displayed in the recognized character display area n of the handwriting input unit 16 is directly used as a search character (string) as a search character input area E1 of the headword search screen G1 displayed on the display unit 17. (See FIG. 7).

  Then, using the recognized character displayed in the recognized character display area n (searched character input area E1) as a retrieved character (string), a headword that matches forward is retrieved from each headword recorded in the dictionary data 22a. (Step S4).

  When a headword that matches the search character (string) is found (step S5 (Yes)), the searched headword is displayed as a list on the display unit 17 (step S6). If no headword is found (step S5 (No)), a message that there is no corresponding headword candidate (see FIG. 7) is displayed on the display unit 17 (step S7).

  Here, when it is desired to correct the recognized character (one character) displayed in the recognized character display area n, when the "correction" key 14d of the key input unit 14 is operated (step S8 (Yes)), one character The process proceeds to correction processing, and other recognition candidate characters stored in the handwriting recognition conversion candidate memory 23b are read out and displayed in a list for the recognized characters to be corrected. When a user desired recognition candidate character is selected from the other recognition candidate characters displayed in the list, the recognition character to be corrected displayed in the recognized character display area n is selected as the selected recognition candidate character. (Step S9), the headword search processing from the dictionary data 22a is executed again (step S4).

  Thereafter, in step S6, in a state where the headwords searched from the dictionary data 22a are displayed in a list, the headword desired by the user is designated by operating the cursor key 14f and the “translation / decision” key 14c is operated. If it is done (step S10 (Yes)), it is confirmed that there is a headword designated by the cursor (step S11 (Yes)), and explanation information corresponding to the designated headword is read from the dictionary data 22a. Is displayed on the display unit 17 (step S12).

  On the other hand, the recognition character strings (search character strings) are collectively displayed in a state where the plurality of recognized characters that are input by handwriting and recognized are displayed as the search character strings in the recognition character display area n (search character input area E1). When the “collective correction” key 14e of the key input unit 14 is operated to automatically correct (step S13 (Yes)), the process proceeds to the collective correction process in FIG. 5 (step SA).

  FIG. 7 shows an entry word search in which a character string (search character string) “prayer snake” erroneously recognized as a target of batch correction processing associated with the handwritten dictionary search processing of the first embodiment of the electronic dictionary device 10 is displayed. It is a figure which shows the display state of the screen G1 and the handwriting input part.

  FIG. 8 is a diagram showing a specific example in which the character string (search character string) “Prayer Snake” misrecognized in FIG. 7 is collectively corrected according to a headword search by replacing candidate characters.

  FIG. 9 is an explanatory information display screen for the headword “hi-just [takene snake]” retrieved from the dictionary in accordance with the recognized character string (search character string) “takene snake” collectively corrected according to the specific example of FIG. It is a figure which shows G2.

  For example, in the handwriting dictionary search process in FIG. 4 according to the handwriting input operation on the handwriting input unit 16 shown in FIG. Is misrecognized, the misrecognized character string “Prayer Snake” is input to the recognized character display area n of the handwriting input unit 16 and displayed on the display unit 17 as shown in FIG. Are displayed in the search character input area E1 of the headword search screen G1 (steps S1 to S5 → S7).

  When the misrecognized character string “Prayer Snake” is input and displayed as a search character string, the “collective correction” key 14e of the key input unit 14 is input (step S13 (Yes)). When the process proceeds to the batch correction process (step SA), first, it is input and displayed in the recognized character display area n in accordance with the correction history of candidate characters recognized in the past stored in the corrected character history memory 23c. Each character of the recognized character string “Prayer Snake” is sequentially replaced, and each time a headword that matches the replaced character string is searched from the dictionary data 22a (step A1).

  Subsequently, as shown in FIG. 8A, other recognition candidate characters corresponding to the characters of the recognition character string “prayer snake” are stored in the handwriting recognition conversion candidate memory 23b. As shown in FIG. 8 (B), the recognition candidate characters are sequentially replaced, and each time, a headword that matches the replaced character string is searched from the dictionary data 22a (step A2).

  Specifically, the first recognition character “Pray” is left as it is, the second recognition character “棍” is sequentially replaced with the second candidate character “恨”, the third candidate character “root”,. Each time, the headword that matches the prefix is searched. In this case, even if the second recognized character “棍” is replaced with all the other recognition candidate characters, the headword that matches forward is not searched, so the next candidate character of the recognized character “snake” after the third character is not searched. Headword search by replacement is not performed. Then, the first recognition character “prayer” is replaced with the second candidate character “bamboo”, and the second recognition character “棍” is replaced with the second candidate character “恨” and the third candidate character “root” in the same manner as described above. ,... Are sequentially replaced, and the headword that matches the prefix is searched each time. In this case, since the headword “Takene snake” that matches with “Takene”, in which the second character is replaced with the third candidate character “Root”, is searched for, the third recognition character “snake” is further added. The second candidate character “蛻”, the third candidate character “蛞”,... Are sequentially replaced, and the headword that matches forward is searched each time. Thereafter, the first character is replaced with the third candidate character “place”, and the headword search associated with replacement of the second and subsequent recognition candidate characters is repeated as described above.

  Thus, when several headwords are searched along with the replacement of the recognized character string “prayer snake” for each character in the steps A1 and A2, when the headword is searched, the searched headword is replaced. Prioritized priorities are sorted in ascending order of number of characters (step A3).

  Separately from this, for each of the searched headwords, the total value of the recognition candidate ranks for each character is calculated, and prioritized and sorted in ascending order of the total value (step A4).

  Then, the headwords sorted in the order of priority in the steps A3 and A4 are displayed as a list of recognized character string candidates after correction associated with the collective correction of the first recognized character string “Prayer Snake”, and can be selected by the user. Is selected (step A5).

  Then, the explanatory information of the headword “hidori [takene snake]” retrieved from the dictionary data 22a according to the collectively corrected recognition character string (search character string) “takene snake” is as shown in FIG. The explanation information display screen G2 is displayed on the display unit 17 (step S12).

  Therefore, according to the handwritten dictionary search function of the first embodiment by the electronic dictionary device 10 having the above-described configuration, when handwritten characters are sequentially input into the handwritten character input areas m1 and m2 of the handwriting input unit 16, the input handwritten characters Is recognized for each character, and the recognized first candidate character is sequentially input to the recognized character display area n and displayed as a search character string in the search character input area E1 of the entry word search screen G1. Here, when the “collective correction” key 14e is input, the recognized character string is replaced with characters after the second candidate for each character, and the headword that matches the replaced character string is searched from the dictionary data 22a. Is done. When a headword is searched, the searched headword is displayed as a list of corrected recognized character strings as candidates and is confirmed as a desired search character string by user selection.

  For this reason, it is possible to automatically correct the misrecognized character string by using the headwords collected in the dictionary data 22a without the need to display and correct other recognition candidate characters one by one.

  The recognized character string to be subjected to the batch correction is preliminarily replaced with the corrected character based on the correction history of the past handwritten recognition character, and the corrected recognized character string is searched by the headword search from the dictionary data 22a. Since the candidate is obtained, it is possible to perform correction more quickly with the learning effect based on the past correction history.

  Further, according to the handwritten dictionary search function of the first embodiment by the electronic dictionary device 10 having the above-described configuration, by replacing each character in the recognized character string based on other recognition candidate characters and correction history and searching for matching headwords. The candidates for recognized character strings that have been collectively corrected are prioritized and displayed in ascending order of the number of replacement characters, or prioritized and displayed in ascending order of the total recognition candidate rank of each character. A desired recognition character string can be found more quickly and used as a search character string.

  In the first embodiment, when Japanese-language dictionary data 22a is targeted and kanji characters are handwritten and characters are recognized to form a search character string, the dictionary data 22a is misrecognized using the headword. A handwritten dictionary search function that corrects all character strings at once has been explained. On the other hand, as will be described in the handwritten dictionary search function of the second embodiment, when English dictionary data 22a is targeted, English characters are input by handwriting and recognized as a search character string. It is also possible to automatically correct English characters that are misrecognized using the headword of the dictionary data 22a.

(Second Embodiment)
FIG. 10 is a flowchart showing the handwritten dictionary search process of the second embodiment in the electronic dictionary device 10.

  FIG. 11 is a diagram illustrating the operation of the handwriting input unit 16 associated with the handwriting dictionary search process of the second embodiment of the electronic dictionary device 10.

  FIG. 12 is a diagram showing a display state of the entry word search screen G1 accompanying the automatic correction of erroneously recognized characters in the handwritten dictionary search process of the second embodiment of the electronic dictionary device 10.

  In the handwritten character input area m1, m2,... Of the handwriting input unit 16, when a handwritten character is input and displayed in order to input a search character string (keyword) (step B1), the input and displayed handwritten character is displayed. The character is recognized (step B2), the recognition candidate character is stored in the handwriting recognition conversion candidate memory 23b in the RAM 23, and the first candidate character is input and displayed in the recognized character display area n (step B3). ).

  At this time, the first candidate character displayed in the recognized character display area n of the handwriting input unit 16 is directly used as a search character (string) as a search character input area E1 of the headword search screen G1 displayed on the display unit 17. (See FIG. 12).

  Then, using the recognized character displayed in the recognized character display area n (searched character input area E1) as a retrieved character (string), a headword that matches forward is retrieved from each headword recorded in the dictionary data 22a. (Step B4).

  When a headword that matches the search character (string) is found (step B5 (Yes)), the headword searched is the headword list area E2 (see FIG. 12) (step B6).

  At this time, among the headwords displayed in the headword list area E2, the headwords designated by the reversing cursor h that can be moved by operating the cursor key 14f, the explanation of the designated headwords. Information is read from the dictionary data 22a and previewed in the preview area P (see FIG. 12) in the headword search screen G1.

  Here, when it is desired to correct the recognized character (one character) displayed in the recognized character display area n, when the “correction” key 14d of the key input unit 14 is operated (step B7 (Yes)), one character The process proceeds to correction processing, and other recognition candidate characters stored in the handwriting recognition conversion candidate memory 23b are read out and displayed in a list for the recognized characters to be corrected. When a user desired recognition candidate character is selected from the other recognition candidate characters displayed in the list, the recognition character to be corrected displayed in the recognized character display area n is selected as the selected recognition candidate character. (Step B8), the headword search processing from the dictionary data 22a is executed again (step B4).

  Thereafter, in step B6, in a state where the headwords retrieved from the dictionary data 22a are displayed in a list, the headword desired by the user is designated by the operation of the cursor key 14f, and the “translation / decision” key 14c is operated. When this is done (step B9 (Yes)), the explanation information corresponding to the designated headword is read from the dictionary data 22a and displayed on the display unit 17 in full screen (step B10).

  On the other hand, for example, as shown in FIG. 11 and FIG. 12, the search character string “imp” is sequentially input along with the handwriting input to the handwriting input unit 16 and the character recognition thereof, and the head matches the search character string “imp”. In the state where the headword to be searched is retrieved from the dictionary data 22a and displayed in the headword list area E2 (steps B1 to B6), as shown in FIG. 11A, the next handwritten character “l” is entered. Input (step B1).

  Here, as shown in FIGS. 11B and 12A, the handwritten character “l” input this time is erroneously recognized as “h” (step B2), and the recognized character display area n and When it is input and displayed in the search character input area E1 (step B3), the headword that matches the search character string “imph” including the misrecognized character “h” is not searched from the dictionary data 22a (step B4). ), It is determined that there is no entry word (step B5 (No)).

  Then, the process proceeds to an automatic correction process for the erroneously recognized character “h”, and the input erroneously recognized character “h” is stored in the handwriting recognition conversion candidate memory 23b as the second candidate character and the third candidate character. ,... Are sequentially replaced (step B11), and a headword search that matches the search character string including the replaced candidate character is executed (step B4).

  Then, as shown in FIG. 12 (B), when the headwords “implacable”, “implant”,... That match the search character string “impl” including the replaced candidate character “l” are searched forward. (Step B4, B5 (Yes)), the searched entry word is displayed in the entry word list area E2 (Step B6).

  When an arbitrary headword “implacable” displayed in the headword list area E2 is designated by the reverse cursor h and the “translation / decision” key 14c is operated (step B9 (Yes)), the designated headword “implacable” is displayed. The explanation information corresponding to the headword “implacable” is read from the dictionary data 22a and displayed on the display unit 17 in full screen (step B10).

  Therefore, according to the handwritten dictionary search function of the second embodiment by the electronic dictionary device 10 having the above-described configuration, a character string that is sequentially handwritten and input by the handwriting input unit 16 is recognized as a search character string, and this one-character input recognition is performed. If a matching headword is not searched when a headword that matches the search character string in front is searched from the dictionary data 22a, the end of the search character string is regarded as a misrecognized character and replaced with another recognition candidate character. The headword that matches the search character string after the replacement is searched again. For this reason, when a misrecognized character is generated in a character string recognized by handwriting input, automatic correction is performed using a headword of the dictionary data 22a, and a dictionary search is performed by inputting a desired search character string more quickly. Can do.
