Abstract:
1. An image processing apparatus for correcting an image captured by an image capturing apparatus including an image sensor having a plurality of pixels arrayed two-dimensionally and on which a shadow of a foreign substance adhering to an optical element placed in front of the image sensor is captured, so as to reduce an influence of the shadow of the foreign substance, comprising: an interpolation unit configured to interpolate a signal of a pixel corresponding to the shadow of the foreign substance on a captured image from a signal of a neighboring pixel outside the shadow of the foreign substance; a designation unit configured to input an instruction to cause said interpolation unit to perform the interpolation; and a control unit configured to control said interpolation unit to perform the interpolation in accordance with an instruction input from said designation unit, to accept a re-execution instruction input from said designation unit if said interpolation unit is unable to perform the interpolation, and to cause said interpolation unit to re-execute the interpolation with changing a parameter for the interpolation or an algorithm for the interpolation.
