Abstract:
An image forming apparatus detects an edge in image data and performs density correction so as to reduce the density of the detected edge. The apparatus then performs screen processing on the image data including the edge that has undergone the density correction, and performs smoothing processing on the edge in screen data obtained through the screen processing.
