area is what is most easily recognizable as what is needed to be adjusted the user may try one of the prefixed hue shift selections but as noted above though the general direction of hue shifting might be correct but the amount of shifting or angle of rotation might not be accurate in the interface 304 of fig3 the hue adjust slider bar 310 shows an available range of hue settings with arrowhead 312 showing the position of system setting prior to adjustment the system automatic parameter adjustment is via several modes of operation selectable 608 by the user in the first mode the system selects 610 a recognizable portion of the image related to a standard parameter for example a background area 312 of the image 306 a background area would be identified by standard histogram background detection algorithms or segmentation algorithms embedded within the scanning system 30 for effectively selecting the portion of the preview image data having a tendency towards a preselected parameter e g primary white as being the nearest standard predominant primary background color other colors of course may be so recognized as being ones that are commonly observed on a regular basis black sky blue apple red and skin tones are typical examples the difference between the selected portion of the previous image data and the predetermined standard parameter must be identified so that a shift can be determined 612 for the preview image data for the selected portion to comprise the standard parameter for example shifting an off white background to a pure white background the interface 304 comprising the suggestion box 314 exemplifies how the suggested shift can be communicated 614 to a user as noted above the system performs image analysis on the preview image data for.
