Image processing to superimpose code on a document image
View Patent ↗An image processing apparatus includes a composite image generator and a print controller. The composite image generator generates a composite image by superimposing, on a document image of a document represented by document data, two-dimensional code images individually corresponding to multiple document elements included in the document. The print controller causes a printer to print the composite image. The composite image generator determines positions of the two-dimensional code images corresponding to the document elements so that the positions do not overlap images of the document elements.
1. An image processing apparatus comprising:
a composite image generator that generates a composite image by superimposing, on a document image of a document represented by document data, two-dimensional code images individually corresponding to a plurality of document elements included in the document; and
a print controller that causes a printer to print the composite image,
wherein the composite image generator determines positions of the two-dimensional code images corresponding to the document elements so that the positions do not overlap images of the document elements,
wherein the document elements are sequenced,
wherein information represented by each two-dimensional code image is stored in a memory, and
wherein the image processing apparatus further comprises an associating unit that associates, with the information represented by each two-dimensional code image corresponding to a corresponding one of the document elements, the information represented by the two-dimensional code images corresponding to the document elements before and after the corresponding one of the document elements.
2. The image processing apparatus according to claim 1 , wherein areas of the two-dimensional code images corresponding to the document elements are smaller than areas of the images of the document elements.
3. The image processing apparatus according to claim 1 , further comprising:
a specifying unit that specifies positions of the images of the document elements in the document image,
wherein the composite image generator includes
a determining unit that determines the positions of the two-dimensional code images corresponding to the document elements on the basis of the positions of the images of the document elements in the document image.
4. The image processing apparatus according to claim 2 , further comprising:
a specifying unit that specifies positions of the images of the document elements in the document image,
wherein the composite image generator includes
a determining unit that determines the positions of the two-dimensional code images corresponding to the document elements on the basis of the positions of the images of the document elements in the document image.
5. The image processing apparatus according to claim 1 , further comprising:
an obtaining unit that obtains color information regarding colors of the document elements,
wherein the composite image generator includes
a determining unit that determines colors of the two-dimensional code images corresponding to the document elements on the basis of the color information regarding the colors of the document elements.
6. The image processing apparatus according to claim 2 , further comprising:
an obtaining unit that obtains color information regarding colors of the document elements,
wherein the composite image generator includes
a determining unit that determines colors of the two-dimensional code images corresponding to the document elements on the basis of the color information regarding the colors of the document elements.
7. The image processing apparatus according to claim 1 , wherein the composite image generator generates the composite image by superimposing, on the document image, the two-dimensional code images individually corresponding to the document elements, and images indicating which two-dimensional code images correspond to which document elements.
8. The image processing apparatus according to claim 2 , wherein the composite image generator generates the composite image by superimposing, on the document image, the two-dimensional code images individually corresponding to the document elements, and images indicating which two-dimensional code images correspond to which document elements.
9. The image processing apparatus according to claim 1 ,
wherein the two-dimensional code images are arranged in a predetermined region, and
wherein the composite image generator includes
a changing unit that changes positions or sizes of the images of the document elements so that the images of the document elements do not contact the predetermined region.
10. The image processing apparatus according to claim 2 ,
wherein the two-dimensional code images are arranged in a predetermined region, and
wherein the composite image generator includes
a changing unit that changes positions or sizes of the images of the document elements so that the images of the document elements do not contact the predetermined region.
11. A non-transitory computer readable medium storing a program causing a computer to execute a process, the process comprising:
generating a composite image by superimposing, on a document image of a document represented by document data, two-dimensional code images individually corresponding to a plurality of document elements included in the document, wherein the document elements are sequenced, and wherein information represented by each two-dimensional code image is stored in a memory;
causing a printer to print the composite image;
determining positions of the two-dimensional code images corresponding to the document elements so that the positions do not overlap images of the document elements, and
associating, with the information represented by each two-dimensional code image corresponding to a corresponding one of the document elements, the information represented by the two-dimensional code images corresponding to the document elements before and after the corresponding one of the document elements.
12. An image processing method comprising:
generating a composite image by superimposing, on a document image of a document represented by document data, two-dimensional code images individually corresponding to a plurality of document elements included in the document, wherein the document elements are sequenced, and wherein information represented by each two-dimensional code image is stored in a memory;
causing a printer to print the composite image;
determining positions of the two-dimensional code images corresponding to the document elements so that the positions do not overlap images of the document elements, and
associating, with the information represented by each two-dimensional code image corresponding to a corresponding one of the document elements, the information represented by the two-dimensional code images corresponding to the document elements before and after the corresponding one of the document elements.
