Abstract
An image file consists of a file header, reduced-and-compressed image data, and compressed original image data. The reduced-and-compressed image data is obtained by compressing reduced image data expressing a reduced image of an original image in serial order of bit planes. The reduced image is then reproduced and displayed on an image display for an image search, in place of the original image itself, whereby efficiency in an image search is improved.
