Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to an enlarged character processing device, which maintains the quality of a printed or displayed image in accordance with a specified enlargement ratio, and
The present invention also relates to an enlarged character processing device that can display or print a required character pattern on a terminal.

[Prior art]

Conventionally, in this type of device, the character pattern before enlarging (hereinafter referred to as the basic pattern) was fixed, and when an enlargement magnification was specified, the characters were enlarged using a certain algorithm according to that magnification. . If the basic pattern is somewhat large, the quality of the characters after enlargement will not deteriorate that much, but if the basic pattern is small or the enlargement magnification is significantly large, the quality of the characters after enlargement will deteriorate. It gets worse.

Furthermore, in order to guarantee the quality of a single character, if a large character set corresponding to the magnification factor is registered in the terminal device, the storage capacity becomes enormous and the price becomes high.

〔the purpose〕

An object of the present invention is to solve the problems of the prior art, to be able to enlarge characters without lowering the print quality of the enlarged characters compared to the characters before enlargement, and to minimize the storage capacity of the terminal device. To provide a compact enlarged character processing device that can reduce the number of characters.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of an enlarged character processing device according to the present invention, and a case where this embodiment device is applied to a character processing device will be described below.

゛ In Fig. 1, 1 is a storage means for storing attributes such as the height and width of the character currently selected and used; 2 is a magnification specifying means for specifying the enlargement magnification of the character;
3 is a calculation means for calculating the enlarged character size from the information in the storage means 1 and the magnification specifying means 2; 6 is a character set corresponding to the character size calculated by the calculation means 3; This is a character set selection means that selects a character set from stored character set storage means. This character set selection means 6 selects a character set corresponding to the character size calculated by the calculation means 3 from the character set storage means. and a correction/enlargement means 5 for correcting and enlarging it. The correction enlargement means 5 is unnecessary when the selected character matches the specified enlargement magnification.

Next, FIG. 2 shows a flowchart of character processing when specifying an enlargement magnification by the enlarged character processing apparatus of the present invention.For the sake of simplicity, the size of each character is assumed to be square, and the enlargement specification is also assumed to be square enlargement. As shown in FIG. 2, in step 1, enlargement is specified to the magnification specifying means 2 through the input line. Then, in step 2, the calculation means 3
Size information is calculated by multiplying the width and height information of the character set information currently in use in the storage means l by an enlargement factor. Then, in step 3, the character set storage means is examined by the character set selection means 6. If the corresponding size exists in the character set storage means, proceed to step 4 and set the enlarged character set area for display or printing in the character processing device to the corresponding character set in preparation for enlarged printing. After rewriting, the width and height information are set to 1 in step 5. This indicates that there is no need to reduce the size when printing later. Also, if there is no corresponding size in the character set storage means in step 3, proceed to step 6, and set the enlarged character set of the character processing device. The area is rewritten to character set information with a size closest to the enlarged character, and in step 7, the enlarged width and height calculated in step 3 are set in preparation for enlarged printing.

Next, FIG. 3 shows a flowchart of the operation of creating enlarged characters by the character set selection means 6 when character set information that does not actually match the enlargement magnification is selected.
First, in step 1, the size of the enlarged character (radius: χ, height: y) is obtained, then in step 2, the selected character set information (radius: m, height: n) is obtained, and in step 3, both are the same. Checks whether it is a character (of size). If they are the same, the selected character set information is used as is, and if they are not the same, proceed to step 4 and change +1/l.
Find l and l' such that A=, X/m, l' + l/l'+-'J/n. Then, proceeding to step 5, a character is constructed by adding +1 dot for each crossed dot in the horizontal direction and +1 dot for each crossed dot in the vertical direction. However, it is assumed that the character set information includes an amount of information such that the sentence l' is an integer.

As a specific example, Fig. 4 shows a case where a character with a size of 1 This shows the character enlargement mode, that is, hi=3, so it can be seen that the enlargement can be done by adding 1 dot to 3 dots.

According to the present invention, it is possible to perform square enlargement using a square basic pattern, and by enlarging vertically and horizontally separately, not only long body enlargement and half body enlargement, but also non-integer multiple enlargement can be performed. Furthermore, since the algorithm in this example is just an example, a more improved algorithm can be used.

〔effect〕

As explained above, according to the present invention, if a character set for each size is prepared, even if a request for enlargement is received, enlarged characters can be obtained without deteriorating the quality of the characters. Therefore, for example, characters of that size can be printed or displayed, and if a certain algorithm is followed, clearer printing (display) can be performed.
