Description
【発明の詳細な説明】 技術分野 本発明は、文字認識装置における認識結果出力方法に
関するものである。Description: TECHNICAL FIELD The present invention relates to a recognition result output method in a character recognition device.
従来技術 従来、文字認識装置では、認識対象文字の大きさや書
体の違いを区別せず、認識結果は、どんな文字に対して
も文字コードだけであり、これを、出力装置（プリンタ
ー、ディスプレイ等）に印字する際には、元の文字の大
きさや書体にはかかわらず、同一のフォント（大きさ、
字体）だけであった。2. Description of the Related Art Conventionally, a character recognition device does not distinguish between the size of a character to be recognized and a difference in typeface, and the recognition result is only a character code for any character, and this is output to an output device (printer, display, etc.). When printing on the same font, regardless of the original character size and typeface, the same font (size,
Font).
第３図は従来の文字認識装置の認識結果を説明するた
めの図である。FIG. 3 is a diagram for explaining a recognition result of a conventional character recognition device.
例えば、第３図のような、見出しが大きなゴシック体
で書かれ、本文は明朝体で書かれた文書を文字認識装置
で読取ると、その結果は文字コード列だけであり、見出
し文字の大きさや、ゴシック体、明朝体の情報が付加さ
れていないために、出力装置（プリンター、ディスプレ
イ等）上では同一の文字となってしまう。For example, as shown in Fig. 3, when a heading is written in a large Gothic font and the text is read in a Mincho font using a character recognition device, the result is only a character code string. Since no Gothic type or Mincho type information is added, the same character is displayed on an output device (printer, display, etc.).
目的 本発明は、文字の大きさ情報あるいは書体情報を文字
認識結果に付加することができる文字認識装置における
認識結果出力方法を提供することを目的とするものであ
る。An object of the present invention is to provide a recognition result output method in a character recognition device capable of adding character size information or typeface information to a character recognition result.
構成 第１図は本発明の一実施例の構成を示すブロック図で
あり、１はスキャナー、２は文字切出し部、３は大きさ
判定部、４は特徴抽出部、５はフォント判定部、６は辞
書検索部、７は結果判定部、８は出力装置である。Configuration FIG. 1 is a block diagram showing the configuration of one embodiment of the present invention, wherein 1 is a scanner, 2 is a character cutout unit, 3 is a size determination unit, 4 is a feature extraction unit, 5 is a font determination unit, 6 Is a dictionary search unit, 7 is a result determination unit, and 8 is an output device.
これは、文字切出し部２から文字の大きさの情報を得
て、文字の大きさを判定する大きさ判定部３と、フォン
ト（書体）の判定を行うフォント判定部５とから出力さ
れる文字の大きさ、フォントの情報を付加して、結果を
出力する結果判定部７と、出力装置８を備えた文字認識
装置である。This is achieved by obtaining character size information from the character cutout unit 2 and determining the size of a character by a size determining unit 3 and a font determining unit 5 that determines a font (font). This is a character recognition device including a result determination unit 7 for adding the size and font information and outputting a result, and an output device 8.
文字の高さ、幅をそれぞれH,Wとし、予め与えられた
標準文字の高さ、幅をHst,Wstとし、倍率をHB,WBとすれ
ば、 HB＝０の時、０＜Ｈ＜（3/4）Hst ＝１ （3/4）Hst≦Ｈ＜（5/4）Hst ＝２ （5/4）Hst≦Ｈ＜（7/4）Hst ＝３ （7/4）Hst≦Ｈ＜（9/4）Hst となる。If the height and width of a character are H and W, respectively, the height and width of a standard character given in advance are H st and W st and the magnification is H B and W B , When H B = 0, 0 <H <(3/4) H st = 1 (3/4) H st ≦ H <(5/4) H st = 2 (5/4) H st ≦ H <( 7/4) H st = 3 (7/4) H st ≦ H <(9/4) H st
ここで、例としてHB＝０〜７、WB＝０〜７の８段階の
値を取るとし、文字コードに１バイトの大きさの情報を
付加すれば第３図の文書は第２図のようになる。Here, as an example, assuming that eight values of H B = 0 to 7 and W B = 0 to 7 are taken, and if information of 1 byte size is added to the character code, the document of FIG. become that way.
第２図は本発明におけるフォント情報付加の説明図で
あり、21はフォント情報（1byte）、22は文字コード（2
byte）を、また、00は明朝体、01はゴシック体、10はナ
ール体、11は教科書体を示す。FIG. 2 is an explanatory diagram of the addition of font information in the present invention, wherein 21 is font information (1 byte), and 22 is a character code (2 bytes).
byte), 00 indicates Mincho style, 01 indicates Gothic style, 10 indicates Nahl style, and 11 indicates textbook style.
フォント判定部５で、一般によく知られたフォント判
定法（各フォントの辞書との照合を行い、最も距離の小
さい文字のフォントと判定するなど）でその文字の書体
を判定し、例えば、明朝体、ゴシック体、ナール体、教
科書体の４種類の情報を付加したものである。The font determination unit 5 determines the typeface of the character by a well-known font determination method (for example, by collating with the dictionary of each font and determining the font of the character having the shortest distance). It adds four types of information: body, Gothic, Nar, and textbook.
効果 以上説明したように、本発明は、認識対象文字の認識
結果の文字コードに付加して、元の文章の文字の大きさ
情報や書体の情報を保存して出力することが可能とな
り、認識結果から文章を再生する場合に、ある程度忠実
に再現することが出来るという利点がある。Effect As described above, the present invention makes it possible to store and output the character size information and the typeface information of the original sentence in addition to the character code of the recognition result of the recognition target character. When the text is reproduced from the result, there is an advantage that the text can be reproduced with some fidelity.
