Abstract

The invention relates to a color image processing apparatus and, more particularly, to adjusting means of a color tone and a sharpness. According to the invention, there is provided a color image processing apparatus characterized by having processing means for performing processes to given color image data; memory means which can store a plurality of processing parameters of the processing means together with peculiar names, and means for searching the registered processing parameters from the memory means.

Claims

1. A color image processing apparatus comprising:

a first input unit adapted to input a word including plural letters selected by a user;

a second input unit adapted to input information indicating plural kinds of parameters instructed by a user;

a registering unit adapted to register the word input by said first input unit with each of the plural kinds of parameters input by said second input unit;

a display unit adapted to display selectively the word registered in said registering unit on a display so that the user can select the word; and

a color image processing unit adapted to perform color image processing based on the plural kinds of parameters based on the word selected by the user.

2. A color image processing apparatus according to claim 1, wherein the color image processing includes color balance adjustment and sharpness adjustment.

3. A color image processing apparatus according to claim 1, wherein the plural kinds of parameters include a parameter to adjust at least a color of CMYK.

4. A color image processing apparatus according to claim 1, wherein the plural kinds of parameters include a parameter to adjust a tone curve.

5. A color image processing apparatus according to claim 1, further comprising a readjusting unit adapted to readjust the plural kinds of parameters.

6. A color image processing apparatus according to claim 1, further comprising a setting condition unit adapted to set a condition based on the plural kinds of parameters,

wherein said color image processing unit is adapted to perform the color image processing based on the condition set in said setting condition unit.

7. A color image processing apparatus according to claim 1, further comprising a reproduction unit adapted to reproduce the image based on said color image processing unit.

8. A color image processing apparatus according to claim 1, wherein the plural kinds of parameters include a parameter to set plural kinds of color conditions.

9. A color image processing apparatus according to claim 1, wherein said color image processing unit performs independently plural kinds of color image processings corresponding to the plural kinds of parameters.

10. A color image processing apparatus according to claim 9, wherein each of the plural kinds of color image processings corresponds to a different one of the plural kinds of parameters.

11. A color image processing method comprising:

a first input step adapted to input a word including plural letters selected by a user;

a second input step adapted to input information indicating plural kinds of parameters instructed by a user;

a registering step adapted to register the word input in said first input step with each of the plural kinds of parameters input in said second input step;

a display step adapted to display selectively the word registered in said registering step on a display so that the user can select the word; and

a color image processing step adapted to perform color image processing based on the plural kinds of parameters based on the word selected by the user.

12. A color image processing method according to claim 11, wherein the color image processing includes color balance adjustment and sharpness adjustment.

13. A color image processing method according to claim 11, wherein the plural kinds of parameters include a parameter to adjust at least a color of CMYK.

14. A color image processing method according to claim 11, wherein the plural kinds of parameters include a parameter to adjust a tone curve.

15. A color image processing method according to claim 11, further comprising a readjusting step adapted to readjust the plural kinds of parameters.

16. A color image processing method according to claim 11, further comprising a setting condition step adapted to set a condition based on the plural kinds of parameters,

wherein said color image processing step is adapted to perform color image processing based on the condition set in said setting condition step.

17. A color image processing method according to claim 11, further comprising a reproduction step adapted to reproduce the image based on said color image processing step.

18. A color image processing method according to claim 11, wherein the plural kinds of parameters include a parameter to set plural kinds of color conditions.

19. A color image processing method according to claim 11, wherein in said color image processing step plural kinds of color image processings corresponding to the plural kinds of parameters are performed independently.

20. A color image processing method according to claim 19, wherein each of the plural kinds of color image processings corresponds to a different one of the plural kinds of parameters.
