US 2022/0407979 A1 · METHOD FOR SCANNING ORIGINALS

Abstract

The invention relates to a method for scanning originals using a scanner, for example a flatbed scanner, said method comprising the steps of: (i) performing a pre-scan using a scanner bed (2) of the scanner, said scanner bed (2) having an extension in the x-direction and in the y-direction, in order to measure an x-extension (4) between a smallest (4a) and a largest extension value (4b) in the x-direction and to measure a y-extension (6) between a smallest (6a) and a largest extension value (6b) in the y-direction in respect of each of the originals on the scanner bed (2), and creating scanning frames (R1, R2, R3, R4, R5, R6) associated with the originals from the respectively measured extension values, (ii) specifying the scanning frame (R1, R2, R3, R4, R5, R6) with the largest y-extension (6) as the leading frame (R4), (iii) defining as subsequent frames (R3, R5) those which are located with their y-extension within a section (10) of the scanning bed which is spanned in the y-direction by the smallest and the largest extension value of the y-extension of the leading frame, (iv) creating an image processing dataset from said section, its leading frame and its subsequent frames, (v) registering said image processing dataset in a list of image processing datasets, (vi) performing steps (ii) to (v), without taking into account the scanning frames already existing in an image processing dataset, until all the scanning frames measured in step (i) are included in an image processing dataset, (vii) capturing image data by scanning the sections of the image processing datasets registered in the list, (viii) cropping the image data of originals from the captured image data along the scanning frame, and (ix) storing the cropped image data of the originals.

(i) performing a pre-scan using a scanner bed (2) of the scanner, said scanner bed (2) having an extension in a x-direction and in a y-direction, in order to measure an x-extension (4) between a smallest (4a) and a largest extension value (4b) in the x-direction and to measure a y-extension (6) between a smallest (6a) and a largest extension value (6b) in the y-direction in respect of each of a plurality of originals on the scanner bed (2), and creating scanning frames (R1, R2, R3, R4, R5, R6) associated with the plurality of originals from the respectively measured extension values,
(ii) specifying a scanning frame (R1, R2, R3, R4, R5, R6) with a largest y-extension (6) as a leading frame (R4),
(iii) defining as subsequent frames (R3, R5) those scanning frames (R1, R2, R3, R4, R5, R6) which are located with their y-extension at least partially, within a section (10) of the scanning bed (2) which is spanned in the y-direction by a smallest and a largest extension value of said y-extension (6) of the leading frame (R4),
(iv) creating an image processing dataset from said section (10), its leading frame (R4) and its subsequent frames (R3, R5),
(v) registering said image processing dataset in a list of image processing datasets,
(vi) performing steps (ii) to (v), for the scanning frames (R1, R2, R3, R4, R5, R6) for which an image processing dataset does not already exist, until all the scanning frames (R1, R2, R3, R4, R5, R6) measured in step (i) are included in an image processing dataset,
(vii) capturing image data by scanning the sections (10) of the image processing datasets registered in the list,
(viii) cropping the image data of the plurality of originals from the captured image data along the scanning frames (R1, R2, R3, R4, R5, R6), and
(ix) storing the cropped image data of the plurality of originals.
