Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a reduced character processing device, which maintains the quality of printed or displayed text in accordance with a specified reduction ratio, and which can process required characters. The present invention relates to a reduced character processing device that can display or print patterns on a terminal.

, [Prior Art] Conventionally, in this type of device, the character pattern before reduction (hereinafter referred to as the basic pattern) is fixed, and when a reduction rate is specified, it is processed by a certain algorithm according to the reduction rate. The text was reduced. If the basic pattern is somewhat large, the quality of the characters after reduction will not deteriorate that much, but if the basic pattern is small or the reduction ratio is significantly large, the quality of the characters after reduction will only deteriorate. However, it may become impossible to distinguish.

Furthermore, in order to guarantee the quality of characters, if all small character sets matched to the reduction ratio are registered in the terminal device, the storage capacity becomes enormous, which not only increases the price but also makes the device huge. There was a drawback.

〔the purpose〕

It is an object of the present invention to solve the problems of the prior art, to be able to reduce one character without lowering the print quality of the reduced character compared to the character before reduction, and to minimize the storage capacity of the terminal device. To provide a compact reduced 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 a reduced character processing device according to the present invention, and a case where this embodiment is applied to a character processing device will be described below.

In Figure 1, l is currently selected and used.
! 2 is a storage means for storing attributes such as the height and width of characters; 2 is a reduction ratio specifying means for specifying the reduction ratio of characters; 3 is a reduction ratio specifying means for specifying the reduction ratio of characters;
6 is a calculation means for calculating the size of the reduced character from the information in the storage means 1 and the reduction ratio 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 includes a search selection means 4 for selecting a character set corresponding to or closest to the character size calculated by the calculation means 3 from the character set storage means, and and correction/reduction means 5 for correcting and reducing the size when the image size does not match the . The correction reduction means 5 is unnecessary if the selected character matches the specified reduction ratio.

Next, FIG. 2 shows a flowchart of character processing when specifying a reduction rate by the reduced character processing apparatus of the present invention.For the sake of simplicity, the size of each character is assumed to be square, and the reduction specification is also assumed to be square reduction. As shown in FIG. 2, in step 1, reduction is specified to the reduction ratio specifying means 2 through the input line. Next, in step 2, the calculation means 3 calculates size information by multiplying the width and height information of the currently used character set information in the storage means 1 by the reduction rate.

Next, in step 3, one character set storage means is checked by the character set selection means 6. If the corresponding size exists in the character set storage means, proceed to step 4, and rewrite the reduced character set area for display or printing in the character processing device to the corresponding character set in preparation for reduced printing. Then, in step 5, the width and height information is set to 1. This indicates a car that does not need to be reduced when printing later. Also, if there is no corresponding size in the character set storage means in step 3, the process proceeds to step 6, and the reduced character set of the character processing device is The area is rewritten to character set information with a size closest to the reduced character, and in step 7, the reduced width and height calculated in step 3 are set in preparation for reduced printing.

Next, FIG. 3 shows a flowchart of the operation of creating reduced characters by the character set selection means 6 when character set information that does not actually match the reduction magnification is selected.
First, in step 1, the size of the reduced character is obtained (width: χ, height: y), 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.

Find fL' such that cross-l/mi÷χ/m, mi'-1/mi'iV/n. Next, proceeding to step 5, a character is constructed by subtracting 11 dots from the top dot in the horizontal direction and -1 dot from the top dot in the vertical direction.

In reality, for example, for reasons of printing quality, characters are created by dividing the entire area into ``Ku xi'' sections, leaving a dark line within each section, and then leaving a thin line within each section. For example, if you have a pattern like the one in Figure 4 (1), first leave a darker line for each crease in the vertical direction as in Figure 4 (2), then leave a darker line in each crease as in Figure 4 (3). Similarly,
Leave a thinner line horizontally for each crease.

As a specific example, FIG. 5 shows the character reduction mode when a 32 x 32 dot character is reduced to a 18 x 1B dot character, and a 24 x 24 dot character is selected without that character, i.e. , Sum = 3, so it can be seen that the reduction can be reduced to 3 dots by thinning out 1 dot.

According to the present invention, it is possible to perform square reduction using a square basic pattern, and by performing vertical and horizontal reduction separately, it is possible to perform not only rectangular size reduction and flat size reduction.

Non-integer reductions can also be performed. Furthermore, if a more improved algorithm is used instead of the algorithm of this example, the print will be even clearer.

〔effect〕

As explained above, according to the present invention, if a character set for each size is prepared, even if a request for reduction is received, the reduced 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.
