Claim:
An image processing device comprising: a first multiplication means for multiplying a pixel signal by a first weighting factor equal to or larger than 0 and equal to or smaller than 1; a delay means for delaying the pixel signal which has not been multiplied yet by the first weighting factor by said first multiplication means by a predetermined number of pixels; a second multiplication means for multiplying the pixel signal which has been delayed by said delay means by a second weighting factor equal to or larger than 0 and equal to or smaller than 1, a total sum of said first and second weighting factors being larger than 1 and smaller than an upper limit; an addition means for adding a result of the multiplication by said first multiplication means and a result of the multiplication by said second multiplication means; and a limit means for limiting a result of the addition by said addition means in such a way that the addition result falls within a maximum density value.
