1. A character segmentation device for removing character frames from an image containing said character frames, these frames having been preprinted in a color that will not vanish when an image of a region to be read is input, and for outputting a resulting image from which the character frames have been removed; said character segmentation device comprising:
image size conversion means for converting the size of said image;
image enhancement means for enhancing said image; and
control means for controlling in such manner that, for poor quality images, the original image size is used and the image is enhanced by said image enhancement means, while for good quality images, the image size is converted by said image size conversion means.
