Image processing apparatus, image processing method, and program

An image processing apparatus comprising:

• a foreign substance information acquisition unit which acquires, from input moving image data, foreign substance information containing a position and size of a foreign substance adhering to an optical element arranged in front of an image sensor in an image capturing apparatus that captures the moving image data;
• a motion vector information acquisition unit which acquires, from the moving image data, a motion vector of a macroblock obtained by dividing the moving image data;
• a correction playback unit which corrects deterioration of image quality caused by the foreign substance, based on the foreign substance information acquired by said foreign substance information acquisition unit, and plays back moving image data;
• and
• a determination unit which determines, based on a motion vector of a macroblock matching the position of the foreign substance in the moving image data to be played back by said correction playback unit, whether to perform foreign substance correction playback of the macroblock.
