[0002]

2. Description of the Related Art Conventionally, in a document processing apparatus for editing each information of characters, figures and images and displaying it on a display screen or printing by a printing means, a color other than black or white is designated for each information. Then, by outputting it to a color printer, a document printed in color can be obtained. FIG. 6 shows the configuration of a conventional document processing apparatus of this type.
In the figure, reference numeral 1 denotes a document processing device, which includes an editing unit 2, a drawing processing unit 3, a cyan drawing memory 4, and a magenta drawing memory 5.
And a yellow drawing memory 6 and a color printer 7.

The editing unit 2 is for inputting or editing each information of characters, figures and images. The drawing processing unit 3 draws each of the above information in each of the drawing memories 4 to 6. The drawing memories 4 to 6 are provided according to the color components of cyan, magenta, and yellow inks for printing the information by the color printer 7, and output the information to the color printer 7. is there. The color printer 7 prints each of the above information on printing paper.

When a color to be printed is designated for each of the information output to the color printer 7, if the composition of each color component of cyan, magenta, and yellow is included, as shown in FIG. 7, eight colors (white, Cyan, magenta, blue, yellow, green,
Red, black) can be expressed. The drawing processing unit 3 has three drawing memories 4 to 6 according to the designation of the color of each information.
It is controlled whether or not each of the above-mentioned information is drawn in each of the above-mentioned information, and after the respective information is drawn, the drawing data of each of the drawing memories 4 to 6 is output to the color printer 7 and the drawing is performed on the color printer 7 side. By associating the drawing contents of the memories 4 to 6 with the output of ink of each color component of cyan, magenta, and yellow,
As a result, it is possible to create a document by color printing including a maximum of eight colors.

However, with respect to the colors of characters, figures, and images that are usually included in one document, black is used much more frequently than other colors. Before printing, it is determined whether or not a character, figure, or image designated in a color other than black or white is included in the entire document before printing. If the characters, figures, or images in the document are specified only in black or white,
A drawing memory for monochrome printing is prepared, characters, figures and images are drawn in the drawing memory, and the drawing result is output to the color printer 7. Also, if any of the characters, figures, or images in the document are specified in a color other than black or white, prepare drawing memories for cyan, magenta, and yellow for color printing and use the drawing memory. Documents that are frequently used, such as characters, figures, and images that have been color-separated for each color component and drawn, and the drawing results are output to the color printer 7 so that only black or white is specified. By reducing the print processing amount, the processing efficiency of the entire document creating apparatus 1 is improved.

[0006]

However, in the above-described conventional document processing apparatus, it is necessary to determine whether or not a document contains characters, figures, or images designated by a color other than black or white. In addition, since it is necessary to search the entire document before printing, it is necessary to check whether a long document such as several tens of pages contains characters, figures, or images in which a color other than black or white is specified. However, there is a problem in that a large amount of processing time is required to determine that, and as a result, work efficiency is reduced.

The present invention has been made in view of the above circumstances, and an object of the present invention is to print a color document without causing a reduction in usage efficiency when printing a black and white document that is frequently used. be to provide a constantly Ru can ensure good working environment print processing apparatus and a printing processing method and a printing apparatus for the operator.

T) 20 is connected. Further, the peripheral device control device 1
An external storage device (FD and HD) 21, which is a peripheral device controlled by the peripheral device control device 17, is connected to the device 7.

The program for controlling the operation of this apparatus is R
Stored in OM12 or RAM13, CPU10
Stores the program in the ROM via the system bus 11.
12 or the RAM 13 is sequentially read, and the intended processing is executed. Next, the operation of the document processing apparatus having such a configuration will be described with reference to the flowcharts of FIGS. Note that, for convenience of description, description will be made with reference to FIGS. 6 and 7.

The flowchart of FIG. 2 starts with printing a document including characters, figures and images in the document processing apparatus. One document consists of a plurality of pages, and the document data itself is stored in the RAM 13 or the external storage device 21. FIG. 4 shows an example of the structure of document data.
In the example shown in FIG. 4, as document data, the document name, the number of digits, the number of lines, the size of characters, the number of pages, and other values related to the format of the document, and the character string stored for each page The character code and the color of each character string, the type and coordinate information of the figure, the color of each figure, the pattern of the image and the color of each pattern are included. However, as long as the storage format of each character, figure, or image in the document is clearly defined and their colors are clearly associated, there is no problem with other data formats.

First, in step S201 of FIG. 2, the page number of the document is acquired from the document data in the register R2. This page number can take any value as long as it is an integer of 0 or more. Next, in step S202, it is determined whether or not the value of the register R2 is 0. The value of register R2 is 0
If so, it is considered that printing of all pages in the document has been completed, and this processing operation is ended. If the value of the register R2 is not 0 but is 1 or more, it is considered that there is an unprinted page, and the process proceeds to the next step S203. In the step S203, the head data stored in the head page of the pages not yet printed is stored in the register R1.
To get to. At this time, the data acquired by the register R1 is either character string data, graphic data, or image data. If it is character string data, the character code string and their colors are acquired in the register R1. If it is graphic data, the type of the graphic, the coordinate point of the graphic, and the color thereof are acquired in the register R1. Further, if it is image data, the image pattern and its color are acquired by the register R1.

FIG. 5 shows each of these data structures. FIG. 5A shows an example of character string data, which is a 2-byte J
The IS code string and the code representing the color are stored. FIG. 5B shows an example of graphic data, in which a rectangle is designated as the type of the graphic, and the coordinate points of the upper left corner and the lower right corner of the rectangle and the codes representing the colors are stored.
FIG. 5C shows an example of image data, in which the number of horizontal dots and the number of vertical dots of the image pattern, the image pattern and a code representing the color are stored.

Conventionally, there is a color code that represents each color component of RGB by a value of 1 byte, but the structure itself of the code is not limited as long as a specific color can be designated. Not a thing. Further, the structure of each of these data is not limited as long as the correspondence between characters, figures, images and their colors is clearly defined.

In step S203, after the head data stored in the head page of the unprinted pages is acquired in the register R1, the process proceeds to step S204 to reset the contents of the register R3. Next, in step S205, the color acquired by the register R1 is determined. If the color is other than white or black, step S20
After proceeding to step 6 and setting the register R3, step S20
Proceed to 7. If the color acquired by the register R1 is white or black, the process directly proceeds to step S207 without executing step S206.

In this step S207, the register R1
It is determined whether or not cyan is included as a color component when the color designated in 1 is output to the color printer 18. FIG. 7 shows the relationship between the three color components of the color printer 18, cyan, magenta, and yellow, and the eight colors that can be expressed by combining them. When black, blue, green, and cyan are colors including a cyan component, and one of those colors is designated as the color of the character, figure, or image acquired in the register R1, the process proceeds to step S208. This step S20
At 8, the cyan component of the character, graphic or image data acquired in the register R1 is drawn in the cyan drawing memory. Specifically, the drawing processing unit 3 in FIG. 6 performs processing for drawing a character, a figure, or an image on the cyan drawing memory 4. At this time, no processing is performed on the other magenta drawing memory 5 and the yellow drawing memory 6.

After executing the step S208, the process proceeds to the next step S209. If cyan is not included as the color component to be output to the color printer 18 in step S207, the process directly proceeds to step S209 without executing step S208. In step S209, it is determined whether or not there is a character, figure, or image data that has not yet been drawn on the page of interest, and if there is, the process proceeds to step S210 and the next character, figure, or After acquiring the image data in the register R1, the process returns to step S205 and repeats the above-described processing. In step S209, if there is no character, figure, or image data that has not been drawn on the page of interest at present, the process proceeds to step S211 in FIG.

In this step S211, the register R3
It is determined whether or not is set. The fact that the register R3 is set in the processing so far means that
This means that a color other than black or white has been designated as the color of any of the characters, figures, or image data stored in the page currently under attention. Therefore, when the register R3 is not set, it is considered that only black or white is designated as the color of the character, figure or image of the page, and the process proceeds to step S222. In step S222, the content of the cyan drawing memory 4 (see FIG. 6) is regarded as the result of drawing in black and white, and the result is output to the color printer 18 (see FIG. 6) as monochrome data. Next, after proceeding to step S223 and subtracting 1 from the value of the register R2, step S20 of FIG.
Return to 2. At this point, the page of interest in the document is moved next.

On the other hand, if the register R3 is set in step S211, the process proceeds to step S212, and the data of the character, figure or image of the page of interest at present is acquired (set) from the beginning in the register R1. In the next step S213, it is determined whether or not magenta is included as the color component of the data acquired in the register R1.
As shown in FIG. 7, when black, blue, red, and magenta are colors including a magenta component, and one of these colors is designated as the color of the character, figure, or image acquired in the register R1. Proceeds to the next step S214.

In step S214, the register R1
The magenta component of the character, figure, or image data acquired in step 1 is drawn in the magenta drawing memory. In particular,
The drawing processing unit 3 in FIG. 6 performs processing for drawing a character, a figure, or an image on the magenta drawing memory 5. At this time, the other cyan drawing memory 4 and yellow drawing memory 6
No processing is performed on.

After executing the step S214, the process proceeds to the next step S215. If magenta is not included as the color component to be output to the color printer 18 in step S213, then step S214 is performed.
The process directly proceeds to step S215 without executing. In step S215, it is determined whether or not there is a character, figure, or image data that has not yet been drawn on the page of interest, and if there is, the process proceeds to step S216.
After acquiring the next character, figure, or image data in the register R1, the process returns to step S213 and the above-described processing is repeated. If it is determined in step S215 that there is no character, figure, or image data that has not been drawn on the current page, the process proceeds to step S217.

In step S217, the character, graphic, or image data of the page of interest at present is acquired (set) from the beginning in the register R1 and the next step S218.
Then, it is determined whether or not yellow is included as the color component of the acquired data in the register R1. As shown in FIG. 7, black, red, green, and yellow are colors including a yellow component, and one of these colors is designated as a color of a character, figure, or image acquired in the register R1. Advances to the next step S219.

In step S219, the register R1
The yellow component of the character, figure, or image data acquired in step 1 is drawn in the yellow drawing memory. In particular,
The drawing processing unit 3 in FIG. 6 performs processing for drawing a character, a figure, or an image on the yellow drawing memory 6. At this time, the other cyan drawing memory 4 and magenta drawing memory 5
No processing is performed on.

After executing the step S219, the process proceeds to the next step S220. If yellow is not included as the color component to be output to the color printer 18 in the step S218, the step S219 is performed.
The process directly proceeds to step S220 without executing.

In step S220, it is determined whether or not there is a character, figure, or image data that has not been drawn on the page of interest at present, and if there is, a step S220.
After proceeding to step 221, the next character, figure, or image data is acquired in the register R1, and then the process returns to step S218 to repeat the above-mentioned processing. If it is determined in step S220 that there is no character, figure, or image data that has not been drawn on the current page, the process proceeds to step S224.

In this step S224, the cyan, magenta, and yellow drawing memories 4,
The results of drawing 5 and 6 are output to the color printer 18. Next, the routine proceeds to step S225, where 1 is subtracted from the value in the register R2, and then the routine returns to step S202 in FIG. At this point, the page of interest in the document is moved next.

The series of processes are repeatedly executed until the value of the register R2 becomes 0 in step S202 of FIG.

Through the above series of processing, when printing a page in which only black or white is designated in the document in this apparatus, a character, figure or image of one color component is developed, and the result is Is output to the color printer 18 as black and white data, and if a color other than black or white is designated even once by any of the characters, figures or images in a page, the characters of that page, Data of figure or image is cyan, magenta,
The color memory 18 is developed in the drawing memories 4, 5, 6 for each color component of yellow, and the result is used as color data in the color printer 18.
By performing processing such as output to a color document, a printing process of a color document in which characters, figures, or images are mixed can be realized without reducing the processing efficiency of a black-only document that is most frequently used in a normal document. be able to.

In the present embodiment, the case where the color components of the color printer 18 are three colors of cyan, magenta, and yellow has been described, but the present invention is not limited to this, and various color combinations of other colors are possible. It goes without saying that the present apparatus can be applied to a color printer capable of expressing Further, in the present embodiment, the case of the color printer capable of expressing eight kinds of colors by combining the respective color components has been described, but the present invention is not limited to this, and it is possible to change the number of the color components to four kinds or It goes without saying that the present invention can be applied to a color printer capable of expressing colors other than 8 types such as 16 types.
