ABSTRACT:
In the image output apparatus of the present invention, a window forming section extracts a window including a notice pixel from bit map data of the image. A contour extraction section extracts contour pixels from the window based on the position of the notice pixel. An outline estimation section estimates an outline based on positions of the contour pixels. A smoothing signal generation section generates a smoothing signal for the notice pixel based on the relative position of the notice pixel and the outline.
