Abstract

Present systems and methods enable user-defined image processing parameters to be applied as intended in some regions of a scanned image without applying them in other regions. More specifically, present systems and methods enable a digital reproduction system to automatically adjust for any inherent interactions between separate image processing modules. Present systems and methods need not be concerned about color adjustments that are made by user-defined settings since the system would automatically adjust for interactions between user-defined settings and automatic adjustments that are made by the system. Present systems and methods provide the flexibility that would be obtained by re-arranging the imaging modules in the processing path of an image processing system.

Claims

1. A system, comprising:

a scan image capture board configured to generate a digital image that represents an image on an original document; and

an image processor configured to receive said digital image and prepare said digital image for output, said image processor being further configured to receive an electronic signal associated with a custom image adjustment setting, to calculate a counter-shift image data value corresponding to said received signal and to assign said counter-shift image data value to pixels in said digital image that are selected for processing during an early applied imaging process.

2. A system as claims in claim 1 wherein said image processor is further configured to calculate a provide a custom image data value corresponding to said received signal and to assign said custom image data value to pixels in said digital image that are selected for processing during a custom imaging process.

3. A system as claims in claim 2 wherein said custom image data value provides a color value for an image data pixel.

4. A system as claimed in claim 3 wherein said custom image data value provides a hue angle for an image data pixel.

5. A system as claimed in claim 3 wherein said custom image data value provides a saturation level for an image data pixel.

6. A system as claims in claim 2 further comprising a video monitor configured to receive image data from said image processor and display a video representations of said received image data.

7. A system as claims in claim 2 further comprising a printer configured to receive image data from said image processor and generate hardcopy reproductions of said received image data.

8. A system as claims in claim 2 wherein said early applied imaging process is automatically applied to said digital image.

9. A system as claims in claim 2 wherein said custom imaging process is applied to said digital imageafter receiving user input.

10. An image processor, comprising:

an image data input configured to receive a digital image;

a user input signal processor configured to receive an electronic signal associated with a user manual adjustment and provide a customized parameter setting corresponding to said user manual adjustment;

a color value correction generator configured to calculate a counter-shift color value setting for pixels in said digital image that are selected for processing during an early applied imaging process;

a color value modifier configured to assign said counter-shift color value setting to said first imaging process selected pixels; and

an custom output processor configured to perform a custom imaging process on said digital image using at least said customized parameter setting.

11. An image processor as claimed in claim 10 wherein said color value correction generator is further configured to calculate a counter-shift color value setting for pixels in said digital image that are selected for processing during an imaging process that is automatically applied to said digital image.

12. A method, comprising:

receiving a digital image;

obtaining a customized parameter setting for a second imaging process;

using said customized parameter setting to calculate a counter-shift color value for pixels in said digital image that are selected for processing during an early applied imaging process;

assigning said counter-shift color value to said first imaging process selected pixels; and

performing said second imaging process on said digital image using at least said customized parameter setting.

13. A method as claimed in claim 12 wherein said first imaging process is automatically applied to said digital image.

14. A method as claimed in claim 12 wherein said first imaging process is a white masking process.

15. A method as claimed in claim 12 wherein said first imaging process is an image annotation process.

16. A method as claimed in claim 12 wherein said customized parameter setting is obtained from signals generated in response to user input at a user interface.

17. A method as claimed in claim 12 wherein said second imaging process is applied to modify an aspect of the color of said digital image.

18. A method as claimed in claim 17 wherein said second imaging process is applied to modify the brightness or contrast of said digital image.

19. A method as claimed in claim 17 wherein said second imaging process is applied to modify the hue of said digital image.

20. A method as claimed in claim 17 wherein said second imaging process is applied to modify the saturation of said image.
