Abstract

A method and system for image scanning presents a user with a suggested parameter adjustment to a scanned image upon system analysis of corresponding scanned image data. A scanner generates initial preview image data of the scanned image. A display displays the image to the user from the initial preview image data. A processor detects a selected portion of the preview image data as having a likelihood of being a standard parameter and for determining a suggested adjustment to the initial preview image data for displaying the selected portion as the standard parameter within the displayed image. The suggested adjustment is communicated to the user and the user implements or overrides the suggested adjustment in a subsequent scan of the image, whereby the user may obtain desired image data for the subsequent scan and the suggested adjustment.

Claims

1. A method for adjusting a custom parameter of a scanned image comprising:

scanning the image for generating initial preview image data;

selecting a portion of the preview image data having a tendency towards a preselected parameter;

identifying a difference between the portion and the preselected parameter; and

,

selectively adjusting the preview image data by the difference for matching the portion with the preselected parameter.

2. The method as defined in claim 1 wherein the selecting comprises determining the portion to comprise a recognizable feature of the initial preview image data.

3. The method as defined in claim 2 wherein the recognizable feature comprises one of background, skin tone, saturated colors or text print.

4. The method as defined in claim 1 wherein the selecting comprises a user designating the portion.

5. The method as defined in claim 4 wherein the designating comprises displaying the scanned image to the user in conformance with the initial preview image data.

6. The method as defined in claim 5 wherein the identifying comprises displaying a suggested parameter value for the portion.

7. The method as defined in claim 6 wherein the selectively adjusting comprises the user accepting the suggested parameter value.

8. The method as defined in claim 7 further comprising a second scanning of the image for generating second preview image data and second displaying the second scanned image wherein the portion comprises the suggested parameter value.

9. An image scanning system for presenting a user with a suggested parameter adjustment to a scanned image upon system analysis of corresponding scanned image data, comprising:

a scanner for generating initial preview image data of the scanned image;

a display for displaying the image to the user from the initial preview image data;

a processor for detecting a selected portion of the preview image data as having a likelihood of being a standard parameter and for determining a suggested adjustment to the initial preview image data for displaying the selected portion as the standard parameter within the displayed image;

a means for communicating the suggested adjustment to the user; and

,

a means for the user to implement or override the suggested adjustment in a subsequent scan of the image, whereby the user may obtain desired image data from the subsequent scan and the suggested adjustment.

10. The scanning system of claim 9 further comprising a printer.

11. The scanning system of claim 9 further comprising a xerographic copier.

12. The scanning system of claim 9 wherein the suggested parameter adjustment comprises image process settings including brightness, contrast, sharpness, hue shift or saturation.

13. The scanning system of claim 12 wherein the suggested parameter adjustment is user selectable from the image process settings.

14. The scanning system of claim 9 wherein the processor includes a histogram detection algorithm or segmentation algorithm for the detecting of the selected portion.

15. The scanning system of claim 14 wherein the selected portion comprises a background area of an illustrative drawing or a photographic image, a saturated color area of a bar graph, a print area of a textual document, or a skin tone area of the illustrative drawing or photographic image.

16. The scanning system of claim 9 wherein the processor accepts a user picked color area as the selected portion.

17. The scanning system of claim 16 further including a means for designating by the user on the display the user picked color area.

18. The scanning system of claim 9 wherein the subsequent scan comprises adjusted image data and the display displays an adjusted image comprising the desired image data acquired from the subsequent scan and adjusted image data.

19. The scanning system of claim 9 that the suggested adjustment is implemented by a manual window portion of the initial preview image data.
