1. A method performed by a processor of a skin imaging apparatus comprising:
obtaining a diffuse reflectance image of an area of skin, the area of skin having been illuminated with polarized light of a first polarization orientation and the diffuse reflectance image having been captured through polarization of a second polarization orientation orthogonal to the first polarization orientation;
extracting from the diffuse reflectance image a pigment component of the diffuse reflectance image, the pigment component being representative of a pigment in the area of skin;
generating a pigment absorption distribution image in accordance with the pigment component;
generating a modified diffuse reflectance image by selectively combining, in accordance with a user input, the diffuse reflectance image and the pigment absorption distribution image so as to selectively reduce or enhance an appearance of the pigment in the modified diffuse reflectance image; and
causing the modified diffuse reflectance image to be displayed, stored, transmitted or further processed.
