Abstract
The quality of the reproduced image in separating the character portions and the areas near or surrounding the character portions has been improved. In particular, as the result of the character edge enhancement, the possibility for mistakenly processing white areas around the character edges has been substantially reduced and the correct detection rate for character edges in high line density areas has been substantially increased.
