Abstract

PURPOSE: To provide a character output device capable of automatically making characters easily visible even when the characters are synthesized with the base of a high density. CONSTITUTION: At the time of synthesizing and outputting divided and stored character data and modification data, a CPU 2 discriminates whether or not the character data or the modification data are present. Then, when both character data and modification data to be outputted are present, whether or not the modification data exceed the prescribed density is discriminated further. Then, when the modification data exceed the prescribed density, after performing trimming for which a portion for one dot adjacent to the character dot of the character data is turned OFF, synthesis and output are performed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a character output device, and more particularly to character output control in a print output device such as a printer.

[0002]

2. Description of the Related Art A conventional print output device is configured to print a character and a decoration for the character as they are, and print the character. Combine the dot patterns (O
R) is printed.

[0003]

However, in the character output device described above, when characters are printed on a dense background, the dots of the characters are mixed with the background.
There is a drawback in that a character having a low density must be used or the character itself must be modified as a reverse character to make the character easier to see.

The character output device of the present invention has been made in view of such a problem, and a character output device capable of automatically printing a character so that the character can be easily seen even if the character is combined on a dense background. To provide.

[0005]

The means of the present invention are as follows. The first discriminating means discriminates whether or not the character data or the modifier data exists when the character data and the modifier data stored separately are combined and output. The second determining means determines whether or not the decoration data exceeds a predetermined density when both the character data to be output and the decoration data are present. The synthesizing and outputting means synthesizes and outputs the character data and the qualification data in a state where the dot pattern of the qualification data adjacent to the character data is erased when the qualification data exceeds a predetermined density.

[0006]

The operation of the means of the present invention is as follows. In combining and outputting the character data and the modification data that are divided and stored, first, it is determined by the first determining means whether or not the character data or the modification data exists, and the character to be output. When the data and the decoration data both exist, it is judged by the second judging means whether or not the decoration data exceeds a predetermined density. Then, when the decoration data exceeds a predetermined density, the dot pattern of the decoration data adjacent to the character data is erased, for example, edging is performed by turning OFF one dot adjacent to the character dot of the character data. Above, the character data and the modification data are combined and output.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to FIGS.

FIG. 1 is a diagram showing the configuration of a character output device to which the present invention is applied. In the figure, reference numeral 2 is a CP that receives the print data 1 and executes a predetermined process described below.
U. Reference numeral 3 is a character memory for storing the character data divided by the CPU 2, and 4 is a decoration memory for storing the modification memory divided by the CPU 2. Reference numeral 5 is a superposition memory as a character output area for storing the data obtained by combining the character data and the decoration data. A print control memory 6 stores the data edited by the overlay memory 5. This print control memory 6
Data of the print output device 8 under the control of the print control device 7.
Printed and output by.

When the CPU 2 synthesizes (overlaps) the character data stored in the character memory 3 with the decoration data stored in the decoration memory 4, the superposition memory 5 is used.
It is determined whether or not the decoration data to be output to the character data exists in addition to the character data, and if it exists, it is further determined whether or not the density of the decoration data exceeds a fixed value (variable).
Then, when the density of the modification data exceeds a certain value, the modification data belonging to the dot (for example, one dot) outside the dot pattern of the character data is turned off and output to the overlay memory 5. Further, when there is character data to be output to the overlay memory 5 but there is no decoration data, or when both character data and decoration data exist but the density of the decoration data does not reach a certain value, or the decoration data If it only exists, it is output to the overlay memory 5 as it is.

FIG. 2 is a flow chart for explaining the operation of the above configuration. First, the print data is divided into character data and decoration data (step S1), the following processing is repeated for each character area, and all the print data is output to the print control memory 6, thus ending the processing. Become.

That is, the character data for one character and the two data output to the same position in the character output area for the character data are compared to determine the presence of the character data and the character data (steps S2 and S3). If only one of the data exists, that data is output to the character output area which is the overlay memory 5 (step S
4, step S5). If two types of data are mixed, it is determined whether the decoration data exceeds a certain density (step S6). If the decoration data does not reach the certain density, the character data is determined. And the dot pattern of the modified data are ORed as they are and output to the character output area (step S7).

On the other hand, when two types of data, character data and decoration data, are mixed and the dot density of the decoration data exceeds a certain value, the decoration data is output to the character output area (step S8). Next, all dots adjacent to the character dots of the character data are turned off from the character output area in which the modifier data is stored (step S9). Then, the character data is OR-outputted to the character output area (step S1).
0).

The data output to the character output area in each of the above cases is output to the print control memory 6 (step S11). Then, the above-described processing is performed for all print data, and ends when there is no print data to be output (step S12).

FIG. 3 is a diagram showing an example in which character data and decoration data are combined and output by the above method. The figure shows a 32 × 32 font image, in which the character data (Roman numeral 9) shown in (a) and the modification data (dot density 2/3 dots / line) shown in (b) are combined. , The characters are hard to see as shown in (c). Therefore, according to the method of the present embodiment, one dot adjacent to the character dot of the character data is turned off and then ORed to output an image in which the character is emphasized as shown in (d). be able to.
(E) shows an image when edging for 2 dots is performed. 3 (f) to (j) or FIG.
(K) to (o) show other examples in which the above-mentioned character data is reduced.

In the embodiment described above, if the dot pattern of the modifier data to be superposed on the character data exceeds a certain density, the outside of the dot of the character data is O.
Characters are automatically framed by FF.
Therefore, there is an advantage that the character can be emphasized without being aware of the modified data, and no special operation for that is required, so that it can be used for general print output relations such as document creation and form creation.

In the above-described embodiment, the density of the decoration data can be set to any size. Further, in the above-described embodiment, the case where the edging with 1 dot or 2 dots turned off is described, but the present invention is not limited to this, and it is a matter of course that edging with respect to any dot is possible.

[0017]

According to the present invention, since the characters are automatically framed, there is an advantage that the characters can be emphasized without being aware of the modification data. Further, since no special operation for that is required, it can be used for all print output relations such as document creation and form creation.
