Abstract:
1. An image processing apparatus comprising: binarization means for binarizing color image data obtained by an image reading process into binary image data and outputting the binary image data; detection means for detecting a symbol area including a plurality of symbols, based on the binary image data binarized by said binarization means; symbol cutting means for cutting the plurality of symbols one by one from the symbol area detected by said detection means, based on the binary image data, and obtaining symbol cutting information indicating each of the plurality of symbols; color allocation means for generating image data corresponding to the symbol area detected by said detection means such that in the image data the plurality of symbols cut from the symbol area are allocated respective representative colors, based on the symbol cutting information obtained by said symbol cutting means and the color image data corresponding to the symbol area; and compression means for compressing the image data corresponding to the detected symbol area generated by said color allocation means in different compression methods in accordance with the number of the representative colors allocated to the plurality of symbols.
