Image processing device and image processing method

An image processing method for performing an image processing operation on an inputted original image, comprising the steps of:

• a first step where the original image undergoes a subtractive process so as to generate a subtractive image;
• a second step for generating a line image from the original image;
• and
• a third step for producing a composite image of the subtractive image and the line image, and
• wherein said first step includes a fourth step for performing a subtractive process on an object area to be emphasized and for removing an area other than the object area so as to generate a first subtractive image, and said third step produces a composite image of the first subtractive image and the line image.

A computer-readable recording medium, which records an image processing program for performing an image processing operation on an inputted original image,

• wherein an image processing program is recorded for a computer to carry out the steps of:
• a first step for performing a subtractive process on the original image to undergo a subtractive process so as to generate a subtractive image;
• a second step for generating a line image from the original image;
• and
• a third step for producing a composite image of the subtractive image and the line image, and
• wherein said first step includes a fourth step for performing a subtractive process on an object area to be emphasized to and for removing an area other than the object area so as to generate a first subtractive image, and said third step produces a composite image of the first subtractive image and the line image.
