Abstract

PURPOSE:To make shifting, displaying and correction of a specified character category by simple operation even when designation of character category is omitted by storing other character categories successively after designated character categories. CONSTITUTION:A result of recognition storing section 15 builds up the result of recognition to a format shown in the figure (a). In this format, a header of 1 byte that indicates the category of data, and data consisting of n1 Chinese characters, n2 Japanese syllabaries and n3 English symbols allotted 2 bytes for each shift character. Code of each character category is written in blank space of 2 bits after code '110000' of the header in the figure (b) at the time of inputting shift character of character category. The figure (c) shows the number of shift characters of each character category written after code '10' of the header of handwritten character input. By this constitution, corresponding shift character can be arrived at by shift even when designation of character category is not made.

Conventionally, in order to recognize handwritten characters, handwritten characters are written in a character frame 2 in a character input area 1 using a tablet 10 illustrated in FIG. 4 using an electronic pen. Further, each key of the function input section 3 is provided to control the handwriting input. Among these, kanji,
Kana and English symbols 4 are character types, and by specifying the next character type immediately before the change, it is useful to increase the mm ratio.

In this case, since the candidate characters stored in the storage section cannot be limited in advance by character type, correct recognition results cannot be obtained. Therefore, it was necessary to move the cursor back, specify a change to the character type, and enter the characters again. This does not place a heavy burden on the operator, and when recording the handwritten results in a journal or the like, there is a problem in that the corrections are overwritten, making it difficult to read.

Conventionally, shifting was performed only for the specified character type, but with the present invention, even if you forget to specify the character type, you can move on to other character types by proceeding with the shift, so the original character can be recognized and displayed. Then a tortoise is formed. Furthermore, even if a character type (incorrect) is discovered after inputting multiple characters, the user only has to return the cursor and correct the characters within the range of the incorrect character type, allowing quick recognition with simple operations.

In the figure, the tablet 10 specifies the character type to be changed, writes handwritten characters in the character input area 1, and sends the characters to the input data storage unit 12 via the input control unit 11, as described in FIG. The designation of the character type and the data of the stroke order, number of strokes, and position are stored in . The character type is specified by the shift control section 16. It is set in advance in the recognition result storage section 15 via. On the other hand, in the present invention, each character is stored in the recognition dictionary section 14 so as to include a shift character of the foreign character type in addition to a shift character of the original character type. For example, for “ko”,
In addition to the original character type ``ko'' in hiragana shift, there are ``ni'' in kanji shift, ``17'' in katakana shift, and symbols. A shift "=" is stored, and the shift character of the character type from the input data storage unit 13 is recognized by comparing it with the candidate character in the recognition dictionary 14. This recognition result is stored in the recognition result storage unit 15Y? -Remember;
It is displayed on the display section 18 via the display control section 17. The g-texture result storage unit 15 assembles the recognition results into the format shown in FIG. 5(α). This format includes a 1-byte header indicating the type of data at the beginning, and 2 bytes for each shift character.
Data consisting of byte allocation, one kanji character, two kana characters, and an English symbol cho is provided. The same figure (6) shows the header code ("110000") when inputting the shift character type.
The code for each character type is written in the 2-bit blank space after the .
