Method and apparatus for generating image file

摘要

Upon generating a plurality of image data sets at different resolutions from a digital image data obtained by a film scanner or the like and recording the data sets in a recording medium as an image file having a hierarchy such as the one defined by the FlashPix standard, image quality degradation caused in generation processing of the image data sets at different resolutions can be minimized. Image data for printing is generated in order to generate photographic print by carrying out interpolation processing by an interpolation processing device (printing image data generating device) on an original image obtained by an image obtaining apparatus. Image data sets at different resolutions are also generated by directly carrying out interpolation processing by an interpolation processing device (stepping resolution image data set generating device) on the original image.
