Abstract
Based on a target pixel of image data obtained by performing a halftone process on multi-gradation image data, the image processing apparatus estimates whether or not the target pixel is a pixel that corresponds to an edge portion of an object included in the image data, and, if the target pixel estimated to be positioned at the edge portion is a white pixel, determines whether or not the target pixel is an isolated pixel based on the peripheral pixels of the target pixel, and corrects the target pixel, which is determined to not be the isolated pixel, to a pixel having a predetermined density or more.
