Abstract

A density corrector performs a density correction processing on a resolution-converted image dataset to obtain a density-corrected image dataset by: determining whether each of first and second pixels in the resolution-converted image dataset is a deletion-target pixel, the first pixels each being a pixel located at a position including a longitudinal edge in a second original image, the second pixels each being a pixel located at a position including a lateral edge in the second original image, patterns of edges in regions in the first and second original images corresponding to the deletion-target pixel being the same; correcting a density of the deletion-target pixel to '0'; and correcting a density of respective pixels other than the deletion-target pixel among the first and second pixels to a value equal to or larger than an original density of the respective pixels.
