<p>The purpose of the invention is to make image quality uniform among pages. A first compression process is applied, using an initial Q factor, to each page image of a comics image formed of a plurality of page images (31-40). A second compression process is applied to the n-th page image in ascending order of the data amounts, after compression, of the page images constituting the comics image to which the first compression process has been applied, such that the target page image data amount is equal to [(overall target data amount) - (total data amount obtained when the second compression process has been applied to page images up to the (n-1)-th page image)] × (data amount of the n-th page image obtained in the first compression process)/[(data amount of the overall comics image obtained in the first compression process) - (total data amount of page images up to the (n-1)-th page image obtained in the first compression process)].</p> |
