Abstract

An image processing apparatus receives print data including text attribute information, and performs specific image processing defined in the print data in advance. The image processing apparatus includes a specific level detection unit for detecting a specific level defined in advance from the text attribute information; and an image processing unit for performing image processing defined in advance on the print data in the specific level detected by the specific level detection unit.

Claims

1. An image processing apparatus for receiving print data of a plurality of pages including text attribute information and having a hierarchy structure according to a tag, and for performing specific image processings defined in advance on the print data, comprising:

a memory;

a central processing unit (CPU) detecting first data specific to a front page to be printed on one page and second data to be printed on other pages according to the tag included in the print data, said first data being defined as data between first specific tags for identifying the front page;

an image processing unit performing a first one of the specific image processings on all objects in the first data, said first one of the specific image processings being different from a second one of the specific image processings to be performed on all objects in the second data; and

a text attribute detection unit for detecting a specific text attribute according to the tag, said specific text attribute being set in the text attribute information and indicated by the tag, said image processing unit performing the specific image processings on the specific text attribute detected by the text attribute detection unit,

wherein said CPU is configured to detect the first data defined as data between specific tags designated as <

front page> and

<

/front page>

,

said first one of the specific image processings is performed to generate a vivid color, and

said second one of the specific image processings is performed to generate a natural color.

2. The image processing apparatus according to claim 1, wherein said CPU is configured to detect the first data including at least one of a paragraph and a text.

3. The image processing apparatus according to claim 1, wherein said image processing unit is configured to perform the specific image processings including at least one of color matching processing, black generation processing, base color removal processing, gradation correction processing, screening processing, and text modification processing.

4. The image processing apparatus according to claim 3, wherein said CPU is configured to detect the first data including a first level.

5. The image processing apparatus according to claim 1, wherein said image processing unit is configured to perform the specific image processings when the tag is recognized, and to perform a normal processing when the tag is not recognized.

6. The image processing apparatus according to claim 1, wherein said image processing unit is configured to perform the specific image processings on the printed data including an XML document.

7. The image processing apparatus according to claim 1, wherein said CPU is configured to detect the first data corresponding to an entire area of the one page.

8. The image processing apparatus according to claim 1, further comprising a storage unit for storing a first color processing table for providing the vivid color and a second color processing table for providing the natural color so that the image processing unit performs the first one to generate the vivid color according to the first color processing table and the second one to generate the natural color according to the second color processing table.

9. An image processing apparatus for receiving print data of a plurality of pages including text attribute information and having a hierarchy structure according to a tag, and for performing specific image processings defined in advance on the print data, comprising:

a memory;

a central processing unit (CPU) detecting first data specific to a front page to be printed on one page and second data to be printed on other pages according to the tag included in the print data, said first data being defined as data between first specific tags designated as <

front path> and

<

/front page>

; and

an image processing unit for, performing a first one of the specific image processings on all objects in the first data, said first one of the specific image processings being different from a second one of the specific image processings to be performed on all objects in the second data,

wherein said first one of the specific image processings is performed to generate a CMYK (cyan, magenta, yellow, and black) mixed color as a black color, and

said second one of the specific image processings is performed to generate a K (black) single color as the black color.

10. The image processing apparatus according to claim 9, further comprising a storage unit for storing a first color processing table for generating the CMYK mixed color as the black color and a second color processing table for generating the K single color as the black color so that the image processing unit performs the first one to generate the CMYK mixed color as the black color according to the first color processing table and the second one to generate the K single color as the black color according to the second color processing table.
