发明名称 Image-processing device processing image data by judging a detected and expanded medium-density field as a non-character edge field
摘要 An image-processing device applies a predetermined process to input image data so as to output the processed image data. The image-processing device comprises a medium-density detection unit, an expansion unit, and a non-character edge judgment unit. The medium-density detection unit detects a medium-density field of an image represented by the image data. The expansion unit applies an expansion process to the medium-density field detected by the medium-density detection unit. The non-character edge judgment unit judges the medium-density field applied with the expansion process by the expansion unit as a non-character edge field of the image represented by the image data.
