    摘要: A method for archiving a master image, including the steps of pre-detecting a resolution of a master image which is at least one of a geometric, a radiometric and a spectral resolution, adaptively matching a resolution of an optical device to the pre-detected master image resolution such that the optical device resolution conforms with minimum resolution for an appropriate scanning theorem, scanning point values of the master image with the resolution from the matching step by the optical device having a photosensitive component, digitizing the point values of the master image from the scanning step, compressing the digitized point values, and storing the compressed point values.
