ABSTRACT:
A multivalued original image is converted to a high-resolution image by interpolation processing and the resultant high-resolution image is subjected to binarization processing to obtain a high-resolution binarized image. This is followed by extraction of a plurality of text regions for every text color, as well as position information and text color information of each text region. First compressed data of the text regions is generated by applying compression processing to the high-resolution binarized images at the positions corresponding to the text regions extracted. Second compressed data is generated by filling text regions in the original image with a prescribed pixel value and applying compression processing to the image obtained by such filling. Compressed image data of the original image is then generated, this data including the first compressed data and the second compressed data as well as the position information and color information of each text region.
