<P>PROBLEM TO BE SOLVED: To provide a data reduction method in which the distortion of an image formed by data is limited. <P>SOLUTION: The data reduction method comprises a step for determining whether source data can be reduced or not. That step includes a step for determining whether clipping has been performed or not, a step for determining whether union has been performed or not, a step for determining whether a large difference is present between the width and the height of the source data or not, a step for determining whether the volume of the source data is small or not, a step for determining whether magnification is performed or not, a step for determining whether the data is compressed or not by Tiff following to reduction, a step for determining whether the magnification has been performed or not if the data are compressed by Tiff following to the reduction, and a step for determining whether the magnification has been performed or not if the data are compressed by Tiff following to the reduction or whether the magnification is larger than a set value or not. <P>COPYRIGHT: (C)2004,JPO |
