Abstract:
1. An image display apparatus which displays one or a plurality of images, which is based on an image data subjected to be processed by a job, at a designated display magnification ratio, said image display apparatus comprising: a storage section for storing a plurality of magnification ratio ranges and a plurality of predetermined thinning rates, each one of said magnification ratio ranges is associated with a respective one of said predetermined thinning rates; a job information downloading section for obtaining an image data pertinent to said image from an apparatus that stores an information about said job; a thinning rate setting section for setting, with reference to said storage section, a thinning rate to a particular one of said predetermined thinning rates based on a first designated display magnification ratio that falls within said magnification ratio range associated with said particular thinning rate; a thinning processing section for carrying out a thinning processing with respect to said image data in accordance with said thinning rate having been set by said thinning rate setting section based on said first designated display magnification ratio, and for storing said image data, which has been subjected to said thinning processing, in said storage section; an image pasting section for pasting an image, which is based on said image data which has been subjected to said thinning processing, into a first frame having a size in accordance with said first designated display magnification ratio; and an image display section for displaying said image which has been pasted into said first frame by said image pasting section, wherein when said first designated display magnification ratio is changed to a second designated display magnification ratio different from said first designated display magnification ratio while said first and second designated display magnification ratios are both within any one of the plurality of magnification ratio ranges stored in the storage section, said image pasting section is configured to: a) utilize said image data that has been subjected to said thinning processing in accordance with said thinning rate set by said thinning rate setting section based on said first designated display magnification ratio; and b) paste said image, which is based on said image data, by magnifying said image so as to fit into a second frame having a size in accordance with said second designated display magnification ratio.
