Abstract:
1. An image processing apparatus for laying out a plurality of first image data in a single page to generate second image data, comprising: a decoding unit configured to decode the plurality of first image data which are compressed by using individual compression parameters; an extraction unit configured to extract, on the basis of the compression parameters of the plurality of first image data, a common compression parameter to compress the plurality of first image data and assigning the common compression parameter to the plurality of first image data; a recompression unit configured to recompress the plurality of first image data by using the common compression parameter assigned by said extraction unit; and an output unit configured to composite the plurality of first image data recompressed by said recompression unit as second image data in the single page and outputting the second image data, wherein said extraction unit calculates an average value of compression information to specify the compression parameters of the plurality of first image data and extracts a compression parameter corresponding to the calculated average value of the compression information as the common compression parameter.
