Abstract
An image processing apparatus including a contour extraction section which extracts a contour pixel of an object from pixels in image data that has tone values of a plurality of colors for each of the pixels; and a contour processing section which executes thinning processing of adjusting a tone value of an object color of the object and trapping processing of adjusting a tone value of a background color among tone values of colors in the contour pixel of the object which is extracted by the contour extraction section or in a contour pixel of the background of the object, wherein the contour processing section links an adjustment amount of the tone value of the background color by the trapping processing to an adjustment amount of the tone value of the object color by the thinning processing.
