Abstract:
1. An image processing device which performs processing on a shadow in an image of an object, said image processing device comprising: an image information obtaining unit configured to obtain information about the image of the object, the information including luminance information which is information about luminance of light from the object and polarization information which is information about polarization of the light from the object; a shadow area extracting unit configured to separately extract an attached shadow area and a cast shadow area from the image of the object based on the luminance information and the polarization information obtained by said image information obtaining unit, the attached shadow area appearing on the surface of the object depending on an angle of incidence light, and the cast shadow area appearing on a surface of a material body other than the object when the light is blocked by the object; and an output unit configured to output information separately identifying the attached shadow area and the cast shadow area extracted by said shadow area extracting unit.
