ABSTRACT:
There is described an image processing apparatus, which makes it possible to easily adjust a width of a line image without deteriorating the image quality of the line image. The apparatus includes a storage section to store a first template and a second template; a first determining section to determine whether or not a target pixel is the specific pixel, based on the first template; a second determining section to determine whether or not the target pixel is the edge pixel, based on the second template; and a line width adjusting section to adjust the width of the line image. When determining that the target pixel is the specific pixel, the target pixel is converted to a black pixel. When determining that the target pixel is not the specific pixel and the target pixel is the edge pixel, the target pixel is converted to a white pixel.
