Apparatus incorporating a linear array scanner for correcting deformities in electronic images produced by the scanner and method of correcting deformities in electronic images produced by linear array scanners.

摘要

Deformities in electronic images produced by a multiple array scanner 10 are corrected by using the scanner to generate an electronic image of a reference pattern 62 disposed at the document platen of the scanner, storing that electronic image in a memory 72, producing skew, misalignment and misabutment signals by analysing the stored image and using the correction signals to produce a corrected electronic image of the reference pattern and to correct the electronic images of originals subsequently scanned by the scanner.
<??>The reference pattern consists of a horizontal line which is used to correct deformities in the images due to misalignment and skew associated with the arrays and a vertical line which is used to correct deformities in the images due to misabutment between the arrays. A pointer system 74, 76 associated with the memory is used to identify a sequence of locations in the memory.
