Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an image processing device, and particularly to an image processing device that visualizes and outputs characters or symbols.

[Prior Art] Conventionally, typical examples of this type of image processing apparatus include display devices, recording devices, and the like.

For example, in a recording device that prints dot character fonts, when printing characters with brightness, a font pattern for characters with brightness is prepared in advance, and a pattern with brightness is selected according to an external instruction. was printing.

Therefore, there is no text font pattern with brightness,
The recording device could not print characters with brightness.

[Problems to be Solved by the Invention] The present invention has been made in view of the above-mentioned conventional technology, and there is a request to output characters with brightness based on an external instruction, and a character font pattern with brightness is required. An object of the present invention is to provide an image processing device that synthesizes an image pattern with a normal character pattern to form a character pattern with brightness when there is no character pattern.

Means for Solving Problem C] As a means for solving this problem, for example, in the image processing apparatus of this embodiment shown in FIG. A normal character font section that stores character patterns, a light character font section that stores character font patterns with brightness (hereinafter referred to as light character font patterns), and a light character flag that selects whether or not to output light characters. and a storage area used when forming light characters.

[Operation] In the configuration shown in FIG. 1, when there is an external write character output request and there is no light character corresponding to the requested character data, a light character is formed, visualized, and output.

[Embodiments] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Further, in this embodiment, an example in which the present invention is applied to a recording device such as a printer will be explained.

FIG. 1 is a block diagram of a recording apparatus as an application example of this embodiment.

In the figure, 1 is the main body of the recording apparatus, and 2 is an external host computer. Reference numeral 3 denotes a CPU that controls everything within the recording apparatus main body 1. 4 is a receiving buffer that inputs data from the host computer 2 and stores the received data. Reference numeral 5 denotes a ROM in which a program of a flowchart shown in FIG. 2, which will be described later, is stored, and a pattern area 5a for storing a write pattern 30 as shown in FIG. 3 is provided inside. 6 is a character font RO in which font patterns such as characters or symbols are stored.
M, and has a normal character font part in which a normal character font pattern is stored and a light character font part in which a character font pattern with brightness and darkness is stored. In addition, 7 is a RAM used as a work area while the CPU 3 is operating, and +';:i is a ROM.
It has a light character flag 7a for determining whether a light character is selected in the light pattern 30 in S, and a storage area 7b used when forming a light character. Further, 8 is an output section, which records characters, symbols, etc. on recording paper.

In the following explanation, it is assumed that light character print output processing is executed when the light character flag 7a is "1", and normal character printing processing is performed when it is "0".
It is sufficient to be able to distinguish between "" and "0", so the present invention is not limited to this.

With the above configuration, when the light character flag 7a is "1", the light pattern 30 (32X
24 dots) is read out from the pattern area 5a to form pattern 4 of the alphabet "A" shown in FIG. 4(a).
1 (32×24 dots) and printed, a light character 42 shown in FIG. 4(b) will be formed.

Hereinafter, the process up to the formation of the above-mentioned light character 42 will be explained according to the flowchart shown in FIG.

First, when power is supplied to this device, in step S1 the RA
The write character flag 7a in M7 is cleared to 0". Next, in step S2, the data sent from the host computer 2 is read from the reception buffer 4. In step S3, this read data is the write character start command code. Determine whether or not.The judgment at this time is “YES”.
In this case, the process moves to step S10, the light character flag 7a is set to "1", and the process returns to step S2.

Further, if it is determined in step S3 that it is not a light character start instruction code, the process moves to the next step S4,
Determine whether the data is a light character end instruction code. If this judgment is, for example, "'YES", the process moves to step Sit, resets the light character flag 7a to O'', and returns to step S2.

Now, if it is determined in step S4 that the code is not a light character end command code, the process moves to step S5. Step S5
, the input data is character code or control code (
For example, line feed, carriage return, etc.). If it is a control code, step S12
After that, normal printing processing is performed and the process returns to step S2. If it is a character code, it is determined in step S6 whether the light character flag 7a is "1" or "0".

When the light character flag 7a is "0", light characters are not printed, so the process goes to step S12, and the pattern corresponding to the character code is read from the normal character font section 6a in the font ROMa and output to the output section 8. Performs normal character printing processing.

Further, when the light character flag 7a is 1'' in step S6, the process moves to step S7, and it is determined whether there is a light character corresponding to the manually input character code.Here, if the light character corresponding to the input character code is If it is determined that there is a
The pattern is read from the light character font section 6b in Me, and in step S9, the read pattern is output to the output section 8 and printed.

If it is determined in step S7 that there is no light character pattern corresponding to the input character code, the process moves to step S13. In step S13, a normal character pattern corresponding to the input character code is converted into a font ROMa.
from the normal character font section 6a in the
7 is stored in the storage area 7b. Next step S14
The write pattern 30 is read out from the pattern area 5a in the program ROM 5, ANDed with the normal character pattern stored in the storage area 7b, and outputted to the output section 8 for printing processing.

For example, in steps S13 and S14, if the character code input from the host computer 2 is a code corresponding to the alphabet A" (41H in ASCII code), the storage area 7b will contain the font shown in FIG. 4(a). When the pattern is stored and the logical product operation is processed using the write pattern 30, a write character 42 as shown in FIG. 4(b) is output.

As described above, according to this embodiment, when it is determined that no light character pattern is stored, it is possible to form a light character from a normal character pattern when a light character output command is received from the outside. becomes.

Further, although this embodiment has been described using only one light pattern 30 as an example, several other light patterns may be provided and means for selecting one of them may be newly provided. It is not limited to the pattern shown in the figure.

Furthermore, in this embodiment, when forming a light character, logical normalization is obtained by a program, but since it is a simple logic 'fgAM calculation, it can be easily achieved by hardware.

Furthermore, although the light pattern and character pattern are 32×24 dots in this embodiment, they are not limited to this either.

Furthermore, although this embodiment has been described with reference to the case where it is applied to a printer, it may also be implemented on, for example, a CRT.

[Effects of the Invention] As explained above, according to the present invention, when the device does not have characters with brightness, it becomes possible to form characters or symbols with brightness on the device itself, so that the characters or symbols with brightness can be formed as intended by the host side. It is possible to process visually thin characters without having to judge whether the device has them or not.
