Abstract:
An image information network comprising first enlargement or reduction processing means for carrying out enlargement or reduction processing on an image represented by image information input thereto, by carrying out first interpolation processing which converts the image information to an image having an arbitrary enlargement or reduction ratio and an arbitrary frequency response characteristic, a first image reproducing apparatus for reproducing the image represented by the image information input thereto from the first enlargement or reduction processing means, second enlargement or reduction processing means for carrying out enlargement or reduction processing on an image represented by image information input thereto, by carrying out second interpolation processing which converts the image information into image information having an enlargement or reduction ratio and a frequency response characteristic both of which are pre-set stepwise and different from a conversion characteristic of the first interpolation processing, and a second image reproducing apparatus for reproducing the image represented by the image information input thereto from the second enlargement or reduction processing means, the image information network further comprising:conversion means for converting the characteristic of the first interpolation processing to a characteristic corresponding to the characteristic of the second interpolation processing so that the image reproduced by the first image reproducing apparatus through the first interpolation processing almost agrees visually with the image reproduced by the second image reproducing apparatus through the second interpolation processing, in terms of the enlargement or reduction ratio and in the frequency response characteristic.
