ABSTRACT:
Generation of ringing components during extraction of striped blue components from an image is suppressed, in an image processing apparatus for removing striped blur components from the image. A preprocess is executed on an image data set, which is obtained by detecting light with line sensors that perform scanning in a sub scanning direction. The preprocess reduces drastic changes in pixel values in a first direction, which is perpendicular to the sub scanning direction. A filter process is executed on the preprocessed image data set to extract image data that represents striped blur components that extend in the sub scanning direction. The extracted image data is subtracted from the image data set to remove striped blur components.
