  FIG. 3 is a display state diagram for explaining a display operation associated with the jump search process (1) of the first embodiment.

  In the jump search process of the first embodiment, an image that is explanatory information corresponding to a desired entry word is displayed by an entry word search process according to a normal dictionary search procedure, and an image of the displayed explanation information image is displayed. A case where a jump search process is performed by directly specifying a search target character string will be described.

  First, in accordance with a normal dictionary search procedure according to a user operation by the input unit 16, a desired type of dictionary is selected and specified, and a search target character string (search word) is input, and a headword search process (12a) is performed. When executed, a headword that matches the input search word is searched from the dictionary database 12d of the designated dictionary and displayed on the display unit 17 as a headword list screen (not shown).

  When a desired headword is selected and designated by a user operation on this headword list screen, explanation information (text) corresponding to the designated headword is read from the dictionary database 12d and displayed on the display unit 17. (Step S1).

  For example, when display of (image) is instructed from the description information (text) corresponding to the headword “strong / symbol” (step S2), as shown in FIG. Is displayed on the display unit 17 (step S3).

  In the display state of the explanation information (image) screen G, jump search processing is activated by input of the jump mode key 16c (step S4), and the pointer displayed on the screen is moved and displayed by the cursor key 16b. When a desired character string, for example, “piano” included in the explanation information (image) is designated as a range (step S5), a character recognition process (12b) is performed on the image of the character string “piano” in the designated range H. Is executed, and the recognized character string “piano” is temporarily stored in the RAM 13 (step S6). Here, as a range designation method in step S5, for example, the pointer is moved and displayed by the cursor key 16b, and the decision key 16d is input at the upper left and lower right of the range to be designated. The specified range can be defined as a rectangle with a diagonal line.

As shown, explanation information (text) corresponding to the entry word “piano” at the selected user-desired position is read from the dictionary database 12d and displayed on the display unit 17 as explanation information (text) screen G3. The

  On the other hand, in step S10, when it is determined that the number of headwords corresponding to the search word “piano” is “1” (step S10 (YES)), in FIG. The displayed headword list screen G2 is not displayed. For example, as shown in FIG. 3D, explanation information (text) corresponding to the one headword candidate “piano” is obtained from the dictionary database 12d. The read information is displayed on the display unit 17 as the explanation information (text) screen G3 (step S12).

  On the other hand, if it is determined in the step S9 that the candidate for the entry word matching the search word “piano” is “0” (none) (step S9 (YES)), The message screen “Search from the text is not found.” Is displayed on the display unit 17, and the character string “piano” that has been recognized and temporarily stored is used as the search term, and the selected jump is performed. From the dictionary database 12d of the previous dictionary, not only the headword matching the search word “piano” but also the character string “piano” included in the description information (text) corresponding to all headwords is searched (step S13). ).

  Then, in the search for the character string in the headword and the explanation information (text) in the step S13, the candidate for the headword or the text in the explanation information (text) corresponding to the search word “piano” is “0” ( No), “1” (present), or a plurality of cases (steps S14 and S15).

  Here, if it is determined that there are a plurality of candidates for the entry word or the character string in the explanation information (text) corresponding to the search word “piano” (step S14 → S15 (NO)), the entry word Then, a list screen of character strings in the explanation information (text) (similar to the headword list screen G2 (FIG. 3C)) is displayed (step S16).

  In the headword and explanation information (text) list of character strings, the headword or the text in the explanation information (text) at the position desired by the user in accordance with the up-down movement display of the reverse cursor C by the operation input of the cursor key 16b. When a column is selected, the description information (text) corresponding to the entry word at the selected position desired by the user or the description information (text) where the character string in the description information (text) is included is the dictionary. It is read from the database 12d and displayed on the display unit 17 as the explanation information (text) screen G3 (see FIG. 3D).

  On the other hand, if it is determined in step S15 that there is “one” candidate for the headword or the description information (text) corresponding to the search term “piano” (step S15 (YES)). ), The description screen (text) or the text in the description information (text) corresponding to the one headword candidate “piano” without displaying the list screen of the headword and the text string in the description information (text). The explanation information (text) where the column candidate “piano” is included is read from the dictionary database 12d and displayed on the display unit 17 as the explanation information (text) screen G3 (see FIG. 3D). (Step S17).

  On the other hand, if it is determined in step S14 that the candidate word string in the search word “piano” or the corresponding character string in the description information (text) is “0” (none) (step) (S14 (YES)), a message screen of “no corresponding candidate” is displayed on the display unit 17, and the series of jump search processing is terminated (step S18 → END).

  Therefore, according to the jump search display function of the first embodiment by the mobile device (electronic dictionary) 10 having the above-described configuration, the description corresponding to the searched entry word in accordance with the entry word search process corresponding to the search word desired by the user. When a range of a desired character string portion in the explanation information (image) G is specified in a state where the information (image) G is displayed, the character string included in the image in the specified range H is character-recognized. . Then, a headword search process by a jump search is executed using a character string in the specified range H in the description information (image) G recognized as a search word, and from the headword list screen G2 searched for a match and the headword list. Since the explanation information (text) screen G3 corresponding to the selected entry word is displayed, the character string information that is the basis of the entry word jump search is given as an explanatory image of the dictionary entry word such as a table, a figure, and an yearbook. Even for information, a jump dictionary search can be easily performed by directly specifying a desired character string in the image information.

  Further, according to the jump search display function of the first embodiment by the mobile device (electronic dictionary) 10 having the above-described configuration, it is matched with the search word recognized by the jump dictionary search in which the character string in the image is directly specified. If there is no corresponding entry word candidate, not only all entry words in the dictionary database 12d but also all explanatory information (text) associated with all entry words are used as search destinations. Since a headword candidate corresponding to the search word or a candidate for a character string in the description information (text) is searched and displayed, a jump dictionary search for obtaining some description information corresponding to the search word to the maximum is performed. Can do.

  In the jump search display function of the first embodiment, a range is specified from the description information (image) corresponding to the desired headword searched and displayed by the headword search processing according to the normal dictionary search procedure. The jump dictionary search is performed using the character string as a search word by character recognition. However, as described as the jump search display function of the second embodiment, a range is specified from the explanation information (image). Instead of performing a jump dictionary search using only the character string recognized as a search word (first), an entry word corresponding to the explanation information (image) where the recognized character string exists is also added to the search word (second). The jump dictionary search may be performed based on the first and second search terms.
