Abstract

PURPOSE:To easily and quickly obtain the characters of a desired character type by providing the selecting means of resembling characters at every character type and outputting selected resembling characters from a recognizing part. CONSTITUTION:A character is recognized by a recognizing part 2 based on X, Y coordinate dot string data from a tablet part 1, and recognition results are sent from a detecting part 5 to a display part 4 when a preferential candidate key is not depressed. When this key is depressed, a KANJI (Chinese character)/HIRAGANA (cursive form of Japanese syllabary) key 31, a KATAKANA (square form of Japanese syllabary) key 32, an alphabetic key 33, a number key 34, or a symbol key 35 are discriminated; and if one of them is depressed, the character of a corresponding character type is sent as the recognition result from the recognizing part 2 to the display part 4 by the designation signal from the detecting part 5.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an online character recognition device that recognizes sentences written in a mixture of a plurality of character types.

(Prior art) Conventionally, in online character recognition devices that recognize sentences with multiple character types, when recognizing characters with similar shapes in multiple character types, this similar character is selected as the next candidate (here , the next candidate means that there are similar characters other than the recognized character). Therefore, in conventional online character recognition devices, the character type is set in advance using one next candidate key, which is a key for setting the character type of the next candidate, and the character mode set for the similar character is The desired character was displayed by changing the .

(Problem to be solved by the invention) However, in the conventional device described above, there is only one next candidate key, and it is necessary to set the character type in advance, so it is difficult to determine whether the displayed character is the desired character. This method has disadvantages in that it is not easy to judge, and it takes time to change the character type. For example, "" written in kanji
When recognizing "Kou" (Hereinafter, characters in "["] indicate characters and numbers in parentheses indicate readings), the recognition result is either the kanji "Kou" or the katakana "Kou". ” (E) Is that so?

You have to distinguish it from the shape of the displayed characters.

Furthermore, since the shapes are similar, it is difficult to distinguish between them, which not only takes time, but also leads to a high frequency of incorrect selection.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems and provide an online character recognition device that recognizes a desired character among characters with similar shapes in a plurality of character types.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention includes a tablet unit for inputting characters by hand, and a recognition result by recognizing input characters based on character information from the tablet unit. In the online character recognition device, the online character recognition device includes a recognition unit that outputs a character and a similar character □ having a shape similar to the character, a storage unit that stores the content of the recognition result, and a display unit that displays the recognition result. It has a selection method that allows you to select similar characters for each character type.

A character type priority candidate detection section is provided which causes the recognition section to output similar characters of a desired character type based on the operation of the selection means.

(Operation) According to the present invention, since the online character recognition device is configured as described above, the technical means operates as follows. If, for example, "Katakana" is selected by operating the selection means, the character type priority candidate detection section instructs the recognition section to output a character similar to "Katakana". As a result of recognizing the input characters, the recognition unit operates to output katakana and display the katakana on the display unit, if it is determined that there are similar characters having similar shapes between kanji and katakana. Therefore, the problems of the prior art described above can be solved.

(Example) An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of an online character recognition device showing one embodiment of the present invention. The online character recognition device of this embodiment is based on a tablet 1. It is composed of a recognition section 2, a memory section 32, a display section 4, and a character type priority candidate detection section 5.

When input characters are written on the tablet, the tablet unit 1 extracts X, Y coordinate string data output from the tablet as the pen moves from pen-on to pen-off. The recognition unit 2 performs recognition processing based on the x and Y coordinate string data from the tablet unit 1, and if there is a next candidate for the character of the recognition result, selects the character according to instructions from the character type priority candidate detection unit, which will be described later. . The memory section 3 is the recognition section 2
Stores the characters of the recognition results created by and the next candidate. The display unit 4 displays the characters resulting from the recognition, and if there is a next candidate, it also displays that fact. An example of the display on the display screen of the display unit 4 is shown in FIG. In the figure, a 6-character type priority candidate detection unit 5 indicates that the next candidate exists by displaying a mark 21 on the character of the recognition result.
supplies a signal specifying a priority character to the recognition unit 2 by pressing a priority candidate key, which will be described later. Here the third
The figure shows an example of priority candidate keys. As shown in the figure, Kanji/Hiragana key 31. Katakana key 32. Alphabet key 33
．． Numerical keys 34 and symbol keys 35 are provided on the tablet section or the like.

Next, the operation of this embodiment will be explained based on the flowchart shown in FIG. Character recognition is performed by the recognition unit 2 based on the X and Y coordinate point sequence data from the tablet unit 1 (steps 101, 102, 103). The priority candidate detection unit 5 determines whether or not the priority candidate key has been pressed (step 104). If the priority candidate key has not been pressed, the first candidate recognized by the recognition unit 2 is displayed on the display screen of the display unit 4 as a recognition result (step 105). If the priority candidate key is pressed, the Kanji/Hiragana key 31. Katakana key 32. Alphabet key 33. number key 34
and symbol key 35 (step 106,
108, 110, 112 and 114). 1 of these
If one priority candidate key is pressed, the recognition section 2 displays the character of the character type corresponding to the priority candidate key on the display section 4 as a recognition result in response to a designation signal from the character type priority candidate detection section 5 (step 107, 109, 111, 113, and 115), the recognition of one character is thus completed (step 116).

Next, the operation will be explained using the specific example shown in FIG. 2 mentioned above.

Here, it is assumed that, for example, "a", "i", and "tsu" are sequentially recognized and displayed on the display unit 4, and the katakana key 32 among the priority candidate keys is pressed. When the written character ``工'' is input using the tablet 1, the recognition unit 2 recognizes the kanji ``工'' (ko) and the katakana ``工'' (e) as candidate characters, but the katakana key 32 is pressed. Therefore, as shown in Figure 2, the display section 4 displays the katakana word ``工''.
(e) is displayed, and a mark 21 indicating the existence of the next candidate
is also displayed.

According to this embodiment, a priority candidate key is provided for each character type, and when there is a next candidate for a recognized character, if the priority candidate key is pressed, the character of the desired character type is selected. An online character recognition device can be provided which has the advantages of:

In the above embodiment, one character type is selected by pressing a plurality of priority candidate keys, but it is clear that selection may be made by operating a selection means corresponding to a similar character type.

(Effects of the Invention) As described above in detail, according to the present invention, a selection means is provided that can select similar characters for each character type, and the recognition unit outputs similar characters of the character type selected by the selection means. This has the effect that characters of a desired character type can be obtained easily and quickly.
