Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a character pattern generating device that can be used in a word processor or the like that handles characters such as Chinese characters.

<Prior Art and Its Disadvantages> In conventional general word processors, the number of dots constituting the characters used is predetermined, such as 16x16, 24x24, 32x32 dots, etc. However, recently, for example, printers and CRTs with different numbers of dots make up characters.
By changing the size and height/width ratio of certain characters in the text to be output, it is possible to emphasize certain characters and output them.
Diversification of character patterns is required.

Conventionally, when generating enlarged characters at an arbitrary magnification (non-integer multiple), it has been considered to simply interpolate the original character pattern.
The characters of X32 dots are changed to 42X42 as shown in Figure 11.
When enlarged to a dot character, the decorative part (the part surrounded by a square frame) becomes very unnatural, which may cause deterioration of the quality of the character.

<Purpose of the Invention> The purpose of the present invention was to solve the above-mentioned conventional problems, and it is possible to apply an arbitrary magnification (non-integer multiple) to the original character pattern without deteriorating the quality of the decorative part in particular. An object of the present invention is to provide a character pattern generation device that generates an enlarged character pattern.

<Configuration and Effects of the Invention> The present invention includes a storage means for storing an original character pattern, and generating the original character pattern as coded information representing a pattern related to the arrangement of dots constituting a character in the row direction or column direction. means 1 for extracting patterns of decorative parts constituting characters based on the coded information; means for removing the decorative parts of the original character pattern from the generated coded information; and the removed coded information. means for generating an enlarged character pattern based on the enlarged character pattern, means for generating a decorative part pattern for the enlarged character pattern, and means for adding a decorative part pattern for the enlarged character pattern to the generated enlarged character pattern. It is characterized by

According to the above configuration, the decorative part will not be abnormally enlarged due to row interpolation or column interpolation during enlargement, and the enlarged character pattern will generate a decorative part according to the number of constituent dots of the enlarged character pattern. quality can be maintained. In particular, the decorative parts of kanji in the Mincho font are a characteristic of the font and add emphasis to the characters, but according to this invention, the characters can be enlarged while maintaining the characteristics of the Mincho font.

<Embodiment> FIG. 1 shows a block diagram of a character pattern generation device according to the present invention. In the figure, 1 is an original character pattern memory, 2 is a code generation section, 3 is an enlarged character pattern generation section, 4 is an enlarged character pattern search correction section, 5 is an enlarged character pattern memory, and 6 is a timing generation section. There is. Original character pattern memory 1 stores original character patterns of all characters to be used. For each original character pattern, coded information is stored in advance by storing the pattern constituting the character as a bit image or by some kind of information compression. Signal S1
is a character designation code, and the original character pattern memory 1
outputs this specified original character pattern data (S2) to the code generator fTs2. The code generation section 2 converts this original character pattern into a code (S3) and outputs it to the enlarged character pattern generation section 3. The enlarged character pattern generation section generates a coded enlarged character pattern based on arbitrarily given enlargement ratio information (the number of dots constituting the enlarged character pattern) for the coded original character pattern data. . The enlarged character pattern search and correction section 4 extracts the decorative part included in this horizontally expanded character pattern by pattern matching, removes it, and assigns a code representing the type of the decorative part to the extracted part. Furthermore, the character pattern is expanded in the vertical direction based on the given vertical expansion rate information (number of dots forming the enlarged character pattern in the vertical direction). after that,
A decorative part corresponding to the number of dots constituting a character is added to a place where a decorative part originally existed. The enlarged character pattern memory 5 stores the enlarged character pattern generated in this way. Note that this is a timing generation section for controlling the timing of each section based on information (S4) instructing how much the character designated as 6 is to be enlarged in the horizontal and vertical directions.

FIG. 2 is a block diagram showing the code generation section 2 in more detail. In the figure, 21 is an original character pattern dot length counter, 22 is an original character pattern dot position counter, 23 is an enlarged character pattern dot length 2 position calculation unit, and 24 is an original character pattern dot length counter.
Reference numeral 25 indicates an original character pattern search section, and 25 indicates a Starro end code determination section. 2) Extracts a series of dot patterns in the column direction of the original character pattern, and counts the length (number of dots) of the series. Further, 22 counts the coordinates representing the position of the series of dot patterns (for example, the first dot of the series of dots). 23 calculates the dot length and dot position according to the character structure and number of dots of the desired enlarged character pattern. Specifically, it is obtained by multiplying the dot length of the original character pattern obtained in step 21 by the horizontal enlargement rate and converting the result into an integer. Further, the dot length and dot position of the enlarged character pattern are determined by multiplying the coordinates of the horizontal axis of the original character pattern dot position determined by 22 by the horizontal expansion rate and converting the result into an integer. On the other hand, 24 searches for information on breaks in a series of dot patterns and dot patterns around the dot pattern. 25 determines the start code and end code of the enlarged series of dot patterns based on this information.

FIG. 3 shows a specific example of the above code generation method. In the figure, (A) shows that when a dot pattern in which a series of three dots in the original character pattern is encoded, it is encoded as shown by the arrow. This is a case where the dot length 3 becomes 4 due to the horizontal expansion of the original character pattern. The start code 3 corresponds to the length of a series of dots in the original character pattern. The end code is encoded as either an independent end mark or a pressure-dependent end mark. Figure (B) is an example where a subordinate end mark becomes an end code, and the dot at the end of scanning line i to be encoded is vertically aligned with the end of another dot pattern adjacent to this dot pattern. If the end code is M, which represents a subordinate end mark, the end code is applied. Figure (C) is an example where independent end marks are applied. If the scanning line i to be encoded and the last dot of i+1 adjacent to this dot pattern are not aligned vertically, an independent end mark is applied. C is applied without representing the mark. An enlarged character pattern is generated by such processing.

FIG. 4 shows an example of an original character pattern composed of 32×32 dots. FIG. 5 is a horizontally enlarged version of the original character pattern shown in FIG. 4 (42x32 dots). A predetermined pattern as a decorative part is extracted from this coded pattern, and the do/nodo corresponding to that part is removed. The part surrounded by a frame in FIG. 5 is the decorative part, and is composed of a unique dot pattern having the above-mentioned independent end marks.

FIG. 6 shows the pattern after it has been removed by the above method. In the figure, marks such as j$-&<> indicate that there was a decorative part in that part. After removing the decorative portion in this manner, the image is enlarged in the vertical direction. This vertical expansion is performed by dot interpolation based on the vertical expansion rate and a proportional formula.

FIG. 7 shows a decorative part of the original character pattern corresponding to the above-mentioned - mark and a pattern of the decorative part to be added to the enlarged character pattern. In the same figure, (A) is the original character pattern, and the decorative part (B) is the number of character constituent dots (
If the width (horizontal or vertical direction) is 32 to 40 dots, (
C) shows the case where the number of character constituent dots is 41 to 56, and (D) shows the case where the number of character constituent dots is 57 to 64. Also, Figure 8! It shows the pattern of the decorative part corresponding to the mark, and (A) is the original character pattern (B) (
C) (D) has a character composition dot number of 32-40.41-5
6. It shows the dot patterns of the decorative and edge portions in the enlarged character patterns corresponding to numbers 6.57 to 64, respectively. In this way, several types of dot patterns for decorative parts are stored in advance for each number of dots forming a character. As described above, a pattern of decorative portions corresponding to the number of dots forming the character after enlargement is added to the portions where the decorative portions have been removed after vertical expansion.

FIG. 9 is an example of the final enlarged character pattern after the decorative portion has been added in this manner. The part surrounded by a frame is a decorative part, and A corresponds to the pattern of the decorative part shown in FIG. 7(C) above, and B corresponds to the pattern of the decorative part shown in FIG. 8(C) above.

Further, FIG. 10 shows printing examples of the results of enlarging other characters with different numbers of character-constituting dots.
