摘要 <P>PROBLEM TO BE SOLVED: To provide an image processing apparatus capable of preventing picture quality from being spoiled when dust detected first is removed during read scan. <P>SOLUTION: The image processing apparatus comprises a dust detection part 1003 which detects where dust is present in an image in a horizontal scanning direction; a dust area specification part 1004 which discriminates between the area where the dust is detected and an area where there is no dust to generate a dust area specifying signal; a dust density detection part 1005 which detects the dust density in the dust area specified with the dust area specifying signal; a density comparison part 1006 which compares image data of the dust area specified with the dust area specifying signal with the dust density detected by the dust density detection part 1005; and a selector 101 which switches image processing according to the comparison result. <P>COPYRIGHT: (C)2006,JPO&NCIPI
