An image processing apparatus that separates components of an image of a subject by imaging the subject. The direction of the polarization main axis of each of the light projecting unit 101 that projects light emitted from the light source onto the subject, the color polarization obtaining unit 102 that obtains the color polarization image of the subject, and the unit pixels that form the color polarization image A polarization information processing unit 104 that generates color polarization information based on the correspondence between the luminance of light transmitted through three or more polarizers and the direction of the polarization principal axis; a light source color information acquisition unit 105 that acquires color information of a light source; An image component separation unit 106 that separates color image components based on polarization information and light source color information.
