Claim One:
1. A scanning method for a large-format scanner system, having at least two image sensors used for scanning a large-format original and cascaded so as to have at least one overlap region, the image information in the at least one overlap region of the image sensors being combined by a stitching process, the at least one overlap region within a search area being searched for image information, the method comprising the following steps: S 1 ) recognizing the texture within the defined search region of the original being scanned; S 2 ) evaluating the information density in the recognized texture to determine a criterion for the texture content; S 3 ) weighting the information density as a function of the criterion for the texture content of the recognized texture; S 4 ) detecting a deviation in congruent image information within the defined search region of the original being scanned; S 5 ) determining a weighted deviation of each measurement point from the weighting derived from the texture and the detected deviation of each measurement, and S 6 ) determining a weighted average of the deviations from these weighted deviations; and S 7 using this weighted average to calculate the deviation of shift values in order to correct the position of the offset image elements so that these image elements can be made congruent.
