Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a color document processing device, and more particularly to a color document processing device that facilitates document coloring processing and color editing processing.

C1 Prior Art] In recent years, Japanese and English document processing devices (word processors) have become widespread due to their ease of use and reduction in price.
Now anyone can immediately obtain beautiful prints of key human-generated document data. On the other hand, as copying machines and printers have become increasingly color-based, there is an increasing demand for color processing of documents in offices.

However, if you want to add a red line to a document, for example, with conventional document processing devices you have no choice but to draw the line on the printed output with a red pencil or color marker. Color any string,
Also, it was not easy to process the color change.

[Purpose] The present invention has been made in view of the above-mentioned drawbacks of the prior art, and its purpose is to perform coloring data processing on arbitrary lines and arbitrary characters of a document, insert red lines, etc. An object of the present invention is to provide a color document processing device that can easily process color documents.

[Example] Hereinafter, an example of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram of a color document processing device according to an embodiment. In FIG. A ROM 3 stores a control procedure program, and a RAM 3 stores document data, color designation data, etc., and stores document data as shown in FIG. 5, for example. In the figure, the document data includes CR (carriage return) and LF (line feed) codes for each line, as is generally well known.
Alternatively, the format is terminated with a CR/LF code, and a designated color code R-W is inserted each time the color designation changes in the document data. In other words, the M5 diagram shows three lines of document data strings, the first line is red (R), the second line is white (W) (black in print), and the third line is text. The case where column 3 is green (G) and character string 4 is white (W) is shown. 4 is the CPUI input/output (Ilo) port, 5

29 is a printer interface for connecting to an external color printer; 30 is a group of key switches for specifying colors included in the keyboard 6;
SWR-3WW), 31 is an externally connected flexible disk device.

In the above configuration, document data and color specification data input from the keyboard 6 are stored in the RAM 3. The same applies when document data that has already been created and saved is read from the disk device 31. Next, RAM
The document data of 3 are sequentially read out for display, and the V-R
The pattern is developed from AM9 to V-RAMII. In this case, the document data is pattern-converted by the character generator 7, and is applied to the data line of each V-RAM via the CPU data bus. The pattern write address is applied to address lines A0-AI7 of each V-RAM via the CPU address bus. Further, if a color has already been designated in this state, any of the color designation data R-W is sent to the color encoder 8 via the I10 port 4. For example, if red (R) is selected, the signal R is L.
The OW level is reached and the color encoder 8 output cover MS E
L -0 LOW OW L/ Herni A: Su, V-RA
When M(R)9 is selected (write enabled) and yellow (Y) is selected, the signal Y becomes LOW level, and the color encoder 8 output becomes MSEL-0 and MSEL-1.
Both become LOW level, and V-RAM (R)9 and
There is a relationship in which four V-RAM (G) 10 are selected. In this way, the color encoder 8 separates the input color designation data into three primary colors according to the so-called additive coloring method, and converts them into a V-RAM selection signal. Of course, a similar method can be used for conversion using the subtractive color method.

Figure 2 (a) to C, d) show the above color specification and each V-RA.
Regarding the diagram showing the relationship with pattern expansion to M, the diagram (&
) is a diagram showing the relationship between document data and designated colors. That is, the character strings A to G in the first line of the document are designated as R (red), the number strings 1 to 7 in the second line are designated as G (green), and the character strings A to C in the third line are designated as Y (yellow). , the following character string A-C is M
(magenta) designation, and character strings 1 to 3 are C (cyan) designation. In addition to this, in the example, B (blue) designation, W
(White) can be specified. However, in the case of W designation,
When this is printed, it is black.

FIG. 5(b) is a diagram showing a pattern stored in the V-RAM (R) 9 when the pattern is developed according to the color specification shown in FIG. 4(a). It can be seen that the pattern related to the own red component, that is, the character string A-G on the first line, and the character strings A-C and A-C on the third line are memorized. If the blank is treated as one pattern, the V-RAM(R) 9 will store the red component of the background pattern. Also, if you want to insert a red line into the document, use V-RAM.
The same applies to USA (c) and (d), where the line pattern may be overridden in (R)9.

Next, the pattern data developed on the V-RAM in this manner is read out when displayed on a CRT. For example, V
- When displaying the pattern data stored in the RAM (R) 9, the pattern data is read out sequentially by the address data RAD generated from the V-RAM address generator 18, and the pattern data is read out in parallel by the shift register (S/R) 15. After serial conversion, each bit is input to the luminance input terminal R of the CRT. Therefore, the pattern data read from the V-RAM(R) 9 is displayed in red on the CRT screen.

Similarly, data read from V-RAM (G) 10 is displayed in green, and data read from V-RAM (B) 11 is displayed in blue. Therefore, other colors can be obtained by additive mixing of these three primary colors.

Next, the operation of coloring or changing the color of the created document data will be described. FIG. 3 is a diagram showing the relationship between CRT scanning lines and displayed characters. The coloring or color change character designation for the screen and the color designation operation are performed using the light pen 20 and the switch group 30 (S) of the keyboard 6.
For example, consider the case of coloring the character strings C to E in FIG. 3 red. In this case, when the light-receiving tip of the light pen 20 is placed on point P on the CRT surface, the beam detection signal FD of the light pen 20 rises to HIGH level when point P lights up due to the scanning beam, and the flip-flop is activated at the edge. Set CF/F)28. At the same time, the signal FD latches the output of the V-RAM address generator 18 into the latch 19, and uses this as the start address of the coloring or color changing process. At this time, the CPUI outputs F/F28 (
PDF) and detects the HIGH level of the F/F28 output, the latch 19 output LADD at that time
At the same time as reading (address AD1), clear F/F 28 (CLR). Next, the operator places the tip of the light pen 26 on point Q on the CRT surface, and in the same way as above, the V-RAM address generator The address value of 18 (for example, ADZ) is latched by the latch 19 and read into the CPU 1.Next, the operator colors the specified character string in the desired color by the above operation.L and X change the color. To do this, the color is specified using the switch group 30 on the keyboard 6. Of course, the above-mentioned area specification may be performed using the cursor keys.

FIG. 4 is a flowchart showing the above-described coloring process or color changing process executed by the CPUI.

In step (S)t, wait for the beam detection timing signal PDF of the light pen 20. When the signal is detected, step S2
Input the V-RAM address latch 19 output (ADZ). In S3, the F/F 28 is cleared, and in S4, the next beam detection timing signal PDF of the light pen 20 is waited for. When this signal is detected, the latch 1 at the next time is cleared in S5.
Input 9 output (ADZ), clear F/F 28 in S6, and wait for color specification input from keyboard 6 in S7.When there is a 0 color specification input, it is determined from the ADI and ADZ already obtained in S8. The corresponding character code stored in the RAM 3 is searched according to the area information. In S9, the corresponding character code is redeployed on the V-RAM according to the color designation data number.

That is, if the color designation is R, the turn is developed only in V-RAM (R) 9, and the contents of the other (7) V-RAM (G) 10 and V-RAM (B) 11 are erased.

Next, the document data created or color-changed as described above is output to the disk 31 or a printer device (not shown).

[Effects] As described above, according to the present invention, color processing operations necessary for normal document processing operations, such as coloring a desired character string, changing the color, or inserting a line in a desired color, can be performed. Since it is easy to do this, it can be used to colorize documents in the office, and it is also easy to create beautiful color layouts, which is extremely effective.
