Abstract

PURPOSE:To prevent an enlarged and a reduced pattern which differ in character kind from being unbalanced by generating magnification correction code signals by character kinds and correcting magnification code signals, and enlarging and reducing the character pattern signal. CONSTITUTION:A 1st storage device 1 which is supplied with a character code signal A outputs a character pattern signal D consisting of a character pattern signal Co and a magnification correction code signal Do corresponding to the kind of characters such as Japanese syllabaries and Chinese characters. With this signal Do, a magnification code signal B supplied to a 2nd storage device 3 is corrected according to the kind of characters and a corrected magnification code signal B1 is outputted. Then an arithmetic unit 2 reduces or enlarged the signal C0 with the signal B1 to prevent the enlarged and reduced patterns which differ in character kind from being unbalanced.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a character generator, and more particularly to a character generator used primarily in computerized phototypesetting machines and the like.

[Conventional technology]

Conventionally, in this type of character generation device, a character code signal is given from the outside, a character pattern signal corresponding to the signal is generated by a storage device, and the character pattern signal and the enlarged,
The arithmetic unit performs processing according to the reduction magnification code signal,
It was generating enlarged and reduced character pattern signals.

FIG. 3 is a block diagram showing an example of a conventional character generating device. When a character code signal A is externally applied to the storage device 11 and a magnification code signal B is applied to the arithmetic unit 12, the arithmetic unit 12 calculates the character pattern signal C0 read from the storage device 11 according to the magnification code signal B. act, expand,
A reduced character pattern signal C1 is generated. Here, the character pattern signal of the character pattern having the coordinates of X+'t as shown in FIG. 4 is expressed as shown in FIG. When the magnification code signal is an enlargement value (reduction value) N, the coordinates when the character pattern signal is enlarged (reduced) are given morphically by the following equation.

(Xn + yr++)=N+(X+, yi) Therefore, the enlarged (reduced) character pattern signal becomes as shown in FIG. Conventional devices uniformly perform the above processing without distinguishing between character types (kanji, symbols, kana, numbers).

[Problem to be solved by the invention]

By the way, when enlarging or reducing character patterns of different character types, the font sizes become unbalanced (
(hereinafter simply referred to as unbalance). Taking kanji and kana as an example, when you enlarge a character pattern that is balanced and high quality at a certain size, the kana will be unbalanced unless it is slightly smaller than the original ratio of the kanji. Also, when reduced, the ratio must be slightly larger than the initial ratio to be unbalanced. A specific example is shown in FIG. In Figure 7, the top row is 2.
The text is double enlarged, the middle row is 1x, and the bottom row is reduced. Based on the balance between the kanji and kana characters in the middle row, the kana for ``kisa'' is too large in the upper row, and the kana for ``kiza'' in the lower row is too small.

In the conventional character generation device described above, the character pattern signal is enlarged or reduced by a magnification value based on a uniform magnification code signal, so there is a drawback that an imbalance occurs for each character type (for example, kanji and kana). .

SUMMARY OF THE INVENTION An object of the present invention is to provide a character generating device that can solve the above-mentioned drawbacks and eliminate imbalances in enlarged and reduced character pattern signals.

[Means to solve the problem]

The character generating device of the present invention includes a first storage device that receives a character code signal and generates a predetermined character pattern signal including a character type magnification correction code signal, and a first storage device that receives the magnification code signal and a character type magnification correction code signal. a second storage device that outputs the corrected magnification code signal; and an arithmetic device that receives the character pattern signal and the corrected magnification code signal and enlarges or reduces the character pattern signal using the corrected magnification code signal. have.

[Effect]

Therefore, when enlarged or reduced character pattern signals of different character types are generated, imbalance between them can be prevented.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of a character generating device of the present invention, and FIG. 2 is a diagram showing an example of a generated character pattern signal.

The first storage device 1 generates a character pattern signal including a character type magnification correction code signal D0 based on the character code signal A. The character type magnification correction code signal Do is a signal for classifying characters in order to finely adjust the magnification to enlarge or reduce each character type.For example, if it is a kanji, it is "C'",
If it is a kana, "Koo" is added as an attribute, and if it is a number, "N" is added as an attribute to the character pattern signal C0.The second storage device 3 uses the magnification code signal B and the character type magnification correction code signal Do to The second storage device 3 has a table as shown in the following table, and outputs the table value according to the input signal. If an enlarged value (reduced value) is output as an example of the value, the conventional arithmetic processing described above can be performed.

The arithmetic device 2 receives the character pattern signal C0 and the magnification code signal B generated from the first storage device 1 and generates an enlarged (reduced) character pattern signal c1. By changing the enlargement/reduction magnification code signal B1 depending on the character type using the second storage device 3, it is possible to generate an unbalanced character pattern signal. An example is shown in FIG.

〔Effect of the invention〕

As explained above, the present invention adds a character type magnification correction code signal to a conventional character pattern signal.
The conventional device can be used as is, and when enlarged or reduced character pattern signals of different character types are generated, it is possible to prevent imbalances between them.
