Abstract

The present invention provides an image processing device able to compress the information volume of attribute data by vectorizing the attribute data. A transmitting image processing device includes an attribute separating unit that extracts attribute data from image data, a vectorization processing unit that vectorizes the attribute data extracted by the attribute separating unit, and a transmission unit that transmits, to another device, the vectorized attribute data that was vectorized by the vectorization processing unit together with the image data. A receiving image processing device includes a receiving unit that receives the image data and the vectorized attribute data that was obtained by vectorizing the original attribute data, as well as a RIP unit that restores attribute data from the vectorized attribute data in order to accurately restore the attribute data that was vectorized.

an attribute separating component configured to extract attribute data from image data;

a vectorization processing component configured to perform vectorization for the attribute data extracted by the attribute separating component; and

a transmitting component configured to transmit, to another device, vectorized attribute data that has been vectorized by the vectorization processing component together with the image data.

2. The image processing device of claim 1, wherein the transmitting component performs non-reversible compression for the image data before transmission, and transmits the vectorized attribute data without performing non-reversible compression for the vectorized attribute data.

3. The image processing device of claim 2, wherein the other device performs image processing for the transmitted image data using the transmitted vectorized attribute data.

4. The image processing device of claim 3, wherein the other device converts the vectorized attribute data into the original attribute data before performing image processing.

6. The image processing device of claim 1, wherein the attribute data is attribute data indicating text or image.

7. The image processing device of claim 1, wherein the transmitted image data is subjected to image processing using attribute data before the attribute data is vectorized.

8. An image processing device, comprising:

an attribute separating component configured to generate attribute data from input image data;

an input image processing component configured to adaptively process input image data on the basis of attribute data generated by the attribute separating component; and

a vectorization processing component configured to perform vectorization for the attribute data generated by the attribute separating component;

wherein, when generating a file for transmission and attribute data of the file using post-input image processing image data generated by the input image processing component and vectorized attribute data generated by the vectorization processing component, the attributes of the vectorized attribute data are preferentially taken to be the attribute data for the file for transmission.

9. The image processing device of claim 8, wherein, when generating the attribute data of the file for transmission, the post-input image processing image data has image attributes, and the vectorized attribute data has vector attribute or text attribute.

10. An image processing device, comprising:
