摘要 |
Dimensional variations, such as skew, alignment and abutment, in an array scanner are corrected by scanning and storing into a storage means an uncorrected electronic image generated from a test pattern. Correctional factors are generated from the stored electronic image. The correctional factors are used to correct the dimensional variations in the electronic image of the test pattern and/or dimensional variations in subsequent electronic image outputted from the scanner.
