Abstract

An image processing system includes a setting section and an image processing section. The setting section sets a process condition of electrophotographic image formation suited to reading of an information image that represents data by a pattern. The image processing section performs an image process for preventing degradation, in image quality, of an image other than the information image under the process condition set through the setting section.

Claims

1. An image processing system comprising:

a control section using at least one central processing unit (CPU) for functioning as;

a setting section that sets a process condition of electrophotographic image formation suited to reading of an information image that represents data by a coded pattern, wherein an image includes the information image; and

an image processing section that performs an image process for preventing degradation, in image quality, of the image other than the information image under the process condition set through the setting section, wherein

the image process performed by the image processing section includes a process of thickening a line whose width is smaller than a minimum width of a solid line contained in the information image.

2. The system according to claim 1, wherein the process condition set through the setting section includes a condition of sharpening lines contained in the information image.

3. The system according to claim 1, wherein the process condition set through the setting section includes at least one of a laser light amount, a charging bias, a developing bias and a developing bias ratio in the electrophotographic image formation.

4. The system according to claim 1, wherein the image process performed by the image processing section further includes at least one of a process of thickening a thickness of a character which is smaller in size than a predetermined point, and a process of correcting a tone.

5. The system according to claim 1, wherein:

a target image is a multicolor image, and

the process condition set through the setting section is applied to images having a color of the information image.

6. An image formation apparatus comprising:

the image processing system according to claim 1; and

an image formation section that performs electrophotographic image formation of the image processed by the image processing section of the image processing system, according to the process condition set through the setting section of the image processing system.

7. The image processing system according to claim 1, wherein the coded pattern comprises a bar code, a two-dimensional bar code, a three-dimensional bar code, a glyph code, or an electronic watermark.

8. An image processing system comprising:

a control section using at least one central processing unit (CPU) for functioning as;

an acceptance section that accepts image data for electrophotographic image formation and a process code that specifies whether or not a process concerning an information image that represents data by a coded pattern is to be performed, wherein an image includes the information image;

a setting section that sets a process condition of the electrophotographic image formation suited to reading of the information image if the process code accepted by the acceptance section specifies execution of the process concerning the information image; and

an image processing section that performs an image process for the image data accepted by the acceptance section if the process code accepted by the acceptance section specifies the execution of the process concerning the information image, wherein

the image processing section performs an image process to prevent degradation, in image quality, of the image other than the information image under the process condition set through the setting section, for the image data accepted by the acceptance section, and

the image process performed by the image processing section includes a process of thickening a line whose width is smaller than a minimum width of a solid line contained in the information image.

9. The image processing system according to claim 8, wherein if a currently setup process condition is different from the process condition of the electrophotographic image formation suited to the reading of the information image, the setting section sets the process condition of the electrophotographic image formation suited to the reading of the information image.

10. The system according to claim 8, wherein the process condition set through the setting section includes a condition of sharpening lines contained in the information image.

11. The system according to claim 8, wherein the process condition set through the setting section includes a condition of at least one of a laser light amount, a charging bias, a developing bias and a developing bias ratio in the electrophotographic image formation.

12. The system according to claim 8, wherein the image process performed by the image processing section further includes at least one of a process of thickening a thickness of a character which is smaller in size than a predetermined point, and a process of correcting a tone.

13. The system according to claim 8, wherein the process code accepted by the acceptance section is specified by an operator.

14. The system according to claim 8, wherein:

a target image is a multicolor image, and

the process condition set through the setting section is applied to images having a color of the information image.

15. An image formation apparatus comprising:

the image processing system according to claim 8; and

an image formation section that performs electrophotographic image formation of an image processed by the image processing section of the image processing system, according to the process condition set through the setting section of the image processing system.

16. The image processing system according to claim 8, wherein the coded pattern comprises a bar code, a two-dimensional bar code, a three-dimensional bar code, a glyph code, or an electronic watermark.

17. A non-transitory computer readable medium storing a program causing a computer to execute a process comprising:

setting a process condition of electrophotographic image formation suited to reading of an information image that represents data by a coded pattern, wherein an image includes the information image; and

performing an image process for preventing degradation, in image quality, of an the image other than the information image under the set process condition, wherein

the image process performed by the image processing section includes a process of thickening a line whose width is smaller than a minimum width of a solid line contained in the information image.

18. The non-transitory computer readable medium according to claim 17, wherein the coded pattern comprises a bar code, a two-dimensional bar code, a glyph code, or an electronic watermark.

19. A non-transitory computer readable medium storing a program causing a computer to execute a process comprising:

accepting image data for electrophotographic image formation and a process code that specifies whether or not a process concerning an information image that represents data by a coded pattern is to be performed, wherein an image includes the information image;

setting a process condition of the electrophotographic image formation suited to reading of the information image if the process code accepted by the acceptance section specifies execution of the process concerning the information image; and

performing an image process for the accepted image data if the accepted process code specifies the execution of the process concerning the information image, wherein

the image processing section performs an image process to prevent degradation, in image quality, of the image other than the information image under the process condition set through the setting section, for the image data accepted by the acceptance section, and

the image process performed by the image processing section includes a process of thickening a line whose width is smaller than a minimum width of a solid line contained in the information image.

20. The non-transitory computer readable medium according to claim 19, wherein coded pattern comprises a bar code, a two-dimensional bar code, a glyph code, or an electronic watermark.
