[Storage of Color Dictionary Information (FIG. 2)] FIG. 2 is a diagram showing the data structure of color dictionary information 11 handled by the document processing apparatus of this embodiment. As shown in FIG. 2, for each color contained in the color dictionary information 11, a tag number 12
The colors are respectively 13 R (red) components, 14 G (green) components, and 1 B (blue) component.
It is expressed as the sum of the color gradation values of the three components of 5. In this example, the gradation of each color component of red 13, green 14, and blue 15 is set to 256 levels (indicated by integer values from 0 to 255), and the larger the value, the higher the brightness of the color. . For example, in Figure 2, the color of tag number 1 is R.
The values of each color component of GB, red 13, green 14, and blue 15 are the same gradation colors (R=128, G=128,
B=128), which is an additive color mixture, and represents gray.

Furthermore, for each color, a plurality of character string information 1
6 is stored. For example, in FIG. 2, text information such as "gray" and "gray" is stored as text string information 16 for the color of tag number 1.

[Storing Operator Color Dictionary Information (FIG. 3)] In the document processing apparatus of this embodiment, the operator is identified by inputting the operator's name from the keyboard 4 at the beginning of the document processing operation.

The operator color dictionary information can be obtained by referring to operator list information 17 as shown in FIG. 3 after identifying the operator. FIG. 3 is a diagram showing the data structure of the operator list information 17. In FIG. 3, the operator list information 17 includes an operator name 18 and a file name 19 of operator color dictionary information. This operator color dictionary information stores information having the same data structure as the color dictionary information 11 shown in FIG. 2.

[Color selection and color dictionary editing processing (FIGS. 4 and 5)
)] Regarding color selection and color dictionary editing processing using the document processing device having the configuration described above and color dictionary information having a data structure, the flow chart shown in FIG.
This will be explained with reference to the operation screen displayed on T1.

First, in step S1, the operator list information 17 is searched from the operator name inputted in advance before the editing operation to obtain the file name of the operator color dictionary, and the operator color dictionary information is read.

Next, in step S2, the operation screen 20 shown in FIG. 5 is displayed on the CRT 1, and then in step S3
The previous color display of the palette 21, which is a collection of color information, is cleared. In step S4, after displaying the color sample contents of the palette 21 on the operation screen 20, the process proceeds to step S5.
The program then advances to wait for an operation input from the keyboard 4.

When there is an operation input from the keyboard 4, the process proceeds to step S6, and the operation input is R (red) 13,
It is checked whether color information is input using G (green) 14 and B (blue) 15. Here, if it is determined that RGB input has been made, the process proceeds to step S7, and the R (red) 1 inputted to the palette 21 in step S6
3, the values of G (green) 14 and B (blue) 15 are set, and the process returns to step S4.

On the other hand, if the operation input is not an RGB input, the process proceeds to step S8, and it is further checked whether the operation input is a color registration process.

If it is determined that the operation input is for color registration processing, the process advances to step S9. Step S
At step 9, the user waits for selection input of a color sample displayed on the palette 21 of the operation screen 20. Once the color sample is selected, the process proceeds to step S10, where the color dictionary information 11 is searched based on the color information of the palette 21 selected in step S9, and the character string 22 corresponding to the selected color is displayed on the operation screen. 20. In step S11, a character string editing input instruction is awaited. Here, when a character string editing instruction is input from the registration instruction 23 on the operation screen 20, the process proceeds to step S12.
Then, the color information of the selected palette 21 and the instructed editing character string are registered in the user color dictionary file, and the process returns to step S5.

Now, if the operation input is not a color registration process in step S8, the process proceeds to step S13, and it is checked whether the operation input is a character string input. here,
If it is determined that the operation input is a character string input, the process proceeds to step S14, and searches the user color dictionary file using the input character string as a key. Next, step S1
In step 5, it is checked whether color information corresponding to the input character string exists as a search result. Here, if there is a corresponding color, the process proceeds to step S16, sets the color information of the search result in the palette 21, and returns to step S4. On the other hand, if the corresponding color does not exist, the process proceeds to step S17, displays an error, and then returns to step S5.

On the other hand, if it is determined in step S13 that the operation input is not a character string input, the process proceeds to step S18, where the operation input is selection of a color displayed on the palette 21 of the operation screen 20. Find out if. Here, if the operation input is not selecting a color for the palette display, the process returns to step S5 and waits for the next operation input.
If the operation input is selection of a color displayed on a palette, the process proceeds to step S19, where the color information of the selected palette 21 is set as the selected color, and the color selection operation is completed.

Therefore, according to this embodiment, by referring to the color dictionary information for the displayed color, it is possible to know the character expressing the color, and furthermore, it is possible to set the color information using the character. Therefore, it is possible to specify a color based on an objective standard of a certain color and a character string that uniquely corresponds to that color, rather than the operator's subjective color identification.

Note that in this embodiment, the method of expressing color information is R.
Although the GB system unit is used, the present invention is not limited to this, and any numerical unit that can uniquely express a color can be used.
Other color representation methods such as YB system can also be used. Furthermore, various methods such as a simple search and a binary tree search method can be used to search the dictionary.

Further, in this embodiment, inputting the operator's name using the keyboard 4 is used as means for identifying the operator, but the present invention is not limited to this. For example, inputting a password, fingerprint, voiceprint, etc. It is also possible to use input means.

The present invention may be applied to a system consisting of a plurality of devices, or may be applied to a device consisting of one device, or may be achieved by supplying a program to the system or device. Needless to say, it can also be applied to cases where
