An operation panel capable of designating whether or not it is, and 9 is a ROM in which a binary pattern used for printer output is stored. The binary pattern used in this embodiment has a fixed size of 16 × 16 dots for each color component, and a pattern corresponding to 256 gradations is stored for each color component.

Reference numeral 10 denotes a binarization pattern pointer table (1), which internally stores a binarization pattern corresponding to each density value (0 to 255) for each of Y, M, C and K color components. The pointer is stored. The table has 256 areas for each color component, and that area is RG

This is a density adjustment flag having a bit size, and in this embodiment, as shown in FIG. 3, it is stored for each type of drawing target of characters, figures, and images.

<Explanation of Processing Operations (FIGS. 4 to 9) Regarding the processing operations of the color image processing apparatus having the above configuration, the flowcharts shown in FIGS. 4, 5, 8 and 9 and FIGS. 6 to 7 will be described. It will be described with reference to FIG.

(1) Initialization Processing (FIG. 4) Here, the initialization processing performed when the color image processing apparatus is powered on or reset will be described with reference to the flowchart shown in FIG.

First, in step S21, various image output environments are initialized, such as setting a default font, clearing the frame memory 6, and initializing the receiving buffer 4.

Next, in step S22, the density adjustment value of each of the YMCK color components (each integer value in the range of -5 to +5) set from the operation panel 8 and the value set in the density adjustment flag 13 are written in characters. Reading is performed for each of the three types of drawing targets, figures and images. Subsequently, in step S23, the YMC read in step S22 is read into the density adjustment value storage unit 12.
K Set the adjustment value for each color. Similarly, step S
In step 24, the density adjustment flag 13 is classified into each drawing target read in step S22 (character, figure, image 3
Set the flag value for each species.

Thereafter, the process proceeds to step S25, 2
The digitized pattern pointer table (1) 10 is set. Here, the contents of the binarized pattern pointer table (1) are set for each color component in accordance with the density adjustment values of the YMCK colors set in the density adjustment value storage unit 12 at this point. The details of this process will be described later with reference to FIG.

Finally, in step S26, the binarization pattern pointer table (2) 11 is set, and the initialization process ends. Binary pattern pointer table (2)
Reference numeral 11 denotes a drawing process, which will be described later, and is used for drawing information of a drawing target for which density adjustment is not performed. The content is the same as the binary pattern pointer table (1) 10 when the density adjustment value is 0.
Therefore, the information of the drawing target for which the density adjustment is not performed is constant regardless of the setting of the density adjustment value.

(2) Binarized pointer table (1) 10
Setting process (FIGS. 5 to 7) Here, the setting process of the binarized pointer table (1) 10 will be described with reference to the flowchart shown in FIG.

The binarized pointer table (1) 10 has Y
It is a table in which density values (0 to 255) for each color component of MCK are associated with the corresponding binarized patterns. In this setting processing, processing for each color component is executed.

First, in step S31, the target color component of the process is set to Y (yellow). Next, proceeding to step S32, the density adjustment value (-5 to +5) of the target color is read. Further, the process proceeds to step S33, and the address of each binarized pattern corresponding to each density value (0 to 255) is obtained and set in the table.

[0032] Now, the addresses P of the binary pattern corresponding to the density value (0 to 255) D is the density adjustment value L, address A _C of the binary pattern of the beginning of each color, the pattern number (0 If 255) is N, it is calculated by the following equation.

When L ≧ 0, N = min (D × (1 + 0.2 × L), 255) When L <0, N = min (D × (1 + 0.1 × L), 255) P = A _C + 32 × N Here, the constant “32” in the above expression represents the number of bytes for one binarization pattern. (Binarization pattern 1
One is, as already mentioned, 16 × 16 dots, that is,
It is 256 bits (= 32 bytes). According to the above equation, the correspondence between each density value (0 to 255) and the binarization pattern number is as shown in FIG. 6 for each density adjustment value.

Thereafter, the processing advances to step S34, where Y
It is determined whether or not the settings for the four color components of MCK have been completed. If it is determined that the processing for all color components has been completed, the binarization pattern table (1) 10
Ends the setting process. On the other hand, if it is determined that the setting process for four colors is not completed, the process proceeds to step S35, the next target color is set, and the process is repeated from step S32.

In this way, the binarization table (1) 1
By setting 0, when the density adjustment value is larger than “0”, the binarization pattern that is darker than usual (that is, when the density adjustment value is “0”) is associated with the same density value. Conversely, when the density adjustment value is smaller than "0", a binarization pattern having a lower density than usual is associated.

FIG. 7 shows the contents of the binarized pattern table (1) 10 when the density adjustment value is "0" and when it is "+5" by taking the Y (yellow) component as an example. As shown in FIG. 7, when the density adjustment value is “+5”, the binarized pattern that is output is a pattern representing a darker density than when the value is “0”. become.

(3) Command Processing (FIG. 8) Each command processing will be described with reference to the flowchart shown in FIG. In the following description, it is assumed that the command to be processed is transmitted from the host 2 and stored in the reception buffer 4.

First, in step S61, the reception buffer 4
The data stored in is read and step S62
Then, it is checked whether or not the data read in step S61 is a density adjustment value setting command. If it is determined that the data is the density adjustment value setting command, the process proceeds to step S63. On the contrary,
If it is determined that the data is not the density adjustment value setting command, the process proceeds to step S65.

In step S63, the values given as parameters associated with the density adjustment value setting command are regarded as the density adjustment values of the YMCK color components in order,
The value is stored in the density adjustment value storage unit 12. Next, in step S64, the binarization pattern table (1) 10 is set. This process is the same as the process performed in the initialization process already described with reference to FIG. After that, the process returns to step S61 and moves to the process of the next data.

On the other hand, if the process proceeds to step S65, it is checked whether the data read from the reception buffer 4 is a density adjustment target designation command. If it is determined that the data is the density adjustment target designation command, the process proceeds to step S66. On the other hand, if it is determined that the data is not the density adjustment target designation command, the process proceeds to step S67, and it is further checked whether the data is a drawing command for characters, figures, or images.

In step S66, the values of 0 to 1 given as parameters associated with the command are sequentially set to characters,
It is regarded as a density adjustment flag for each of the figure and the image, and this is set in the density adjustment flag 13. In the following process, if the value of the flag is "1", it is considered that the density adjustment is performed on the data of the type corresponding to the flag, while if the value is "0", the density adjustment is not performed. Consider as a thing. After that, the process returns to step S61 and moves to the process of the next data.

In the processing of step S67, when it is judged that the received data is the drawing command of the character, figure, or image, the processing proceeds to step S68 and the drawing processing is performed, and then the processing proceeds to step S61. return,
Move on to the processing of the next data. The details of the drawing process will be described later. On the other hand, if it is determined that the data is not the drawing command, the process proceeds to step S69.
Proceed to to process other commands. Although detailed description of other command processing is omitted, processing of various commands such as a paper discharge command, a reset command, and a character typeface selection command corresponds to this.

By the above processing, when the density adjustment value is specified by the command from the host 2 or the density adjustment flag is specified for each type of drawing target of characters, figures, and images, the specification is made. Binarization pattern table (1) 10, density adjustment value storage unit 12, density adjustment flag 1
Reflected in 3.

The binarized pattern pointer table (1) 10, the binarized pattern pointer table (2) 11 and the density adjustment flag 13 thus set are
It is used in the drawing process as follows.

(4) Drawing Process (FIG. 9) Here, the binarized pattern pointer table (1) 10 in which the values are set, the binarized pattern pointer table (2) 11 and the density adjustment flag 13 are used. The drawing process executed as described above will be described with reference to the flowchart shown in FIG. Prior to drawing characters, figures, images, etc., in step S701, it is first determined in step S701 whether or not density adjustment is effective for each type of drawing data to be drawn.
Look up. When the density adjustment is to be effective in the drawing process, the process proceeds to step S702, and the binary pattern table (1) 10 is selected as the binary pattern pointer table to be referred to. On the other hand, if the density adjustment is not effective, the process proceeds to step S703, and the binarized pattern pointer table 2 (11) is selected as the binarized pattern pointer table to be referred to later.

Next, in step S704, it is checked whether or not the data to be drawn is an image.
Here, if it is determined that the data is not an image, the process proceeds to step S705, and after that processing step,
Draw characters or figures. In step S705, the color designation value (RGB format) designated for the character or figure to be drawn is converted into each density value of YMCK (value range is 0 to 255). Further, step S7
In 06, the binary pattern corresponding to each density value of YMCK obtained in step S705 is obtained by referring to the selected binary pattern pointer table.

In step S707, a character or graphic pattern to be drawn is generated. Then, in step S708, step S706 and step S707.
The bit-wise logical product (AND) of the binarized pattern and the character / graphic pattern obtained by the above is taken, the result is stored in the corresponding position of the frame memory 6, and the drawing process is ended.

On the other hand, if it is determined in step S704 that the data to be rendered is image rendering, the process proceeds to step S709.
After that processing step, an image is drawn. In drawing an image, each pixel forming the image data is RG
Since the color is represented by the B component, processing is performed for each pixel.

First, in step S709, data (RGB expression) for one pixel is read and converted into YMCK density values. Next, in step S710, a binarization pattern corresponding to each density value of YMCK is acquired. The binary pattern pointer table used at this time is either the binary pattern pointer table (1) or (2). Thereafter, in step S711, the process draws one pixel in the frame memory 6. Step S712
Then, check whether drawing of all the pixels of the image is finished, and if drawing of all the pixels of the image is not finished,
The process returns to step S709 to process the next pixel. On the other hand, if the drawing of all pixels is completed, the drawing process is ended.

As described above, depending on whether or not density adjustment is performed on data to be drawn at the time of drawing processing, 2
One of the two binarization pattern pointer tables is used separately, and the data of the target for which the density adjustment is to be performed is drawn with the density adjusted as instructed, and the data of the target that does not need the density adjustment is adjusted regardless of the density adjustment value. Instead, it will be drawn with the original density.

Therefore, according to this embodiment, it is possible to adjust the density of only the data to be drawn of the type (character / figure / image) designated by the operation panel or command and output and record the image.
