摘要： An image processing apparatus includes an edge-portion detector, an edge-width detector, and a tone correction unit. The edge-portion detector detects a pixel of an edge portion by determining whether or not each of pixels constituting image data which has been input is a pixel which is included in the edge portion. The edge-width detector detects, for the pixel of the edge portion detected by the edge-portion detector, an edge width which is a width of the edge portion. When the edge width detected by the edge-width detector is smaller than a value which is set in advance, the tone correction unit performs tone correction differently in accordance with the detected edge width.
