Abstract (en)

[origin: WO2015110459A1] The invention relates to a method for scanning large-format scan templates (4) with an automatic dynamic scale correction function during the scanning process by means of a scanner (1) which has image capturing elements (2) arranged in a cascading manner in order to scan the scan template (4), wherein image information of adjacent sensor elements (11 to 14) is assembled by means of a stitching method and shift values (Vn) are ascertained in said elements. The method has the following steps: S1: deriving shift values (V) for each image line of the assembled image by interpolating the y direction components of the n shift values (Vn), S2: comparing the shift values (V) with a target value (S) in order to determine a relative deviation for each image line and adding the relative deviations until the sum has reached a value which corresponds to the smallest possible error correction for scaling the image information, and S3: scaling the image information or image signals by taking on the value for the error correction.
