Claim One:
1. An image processing method, comprising: obtaining a normal image captured with all polarization components of light from an object, and a polarization image captured with specific polarization components out of all the polarization components of the light; generating a difference image between the normal image and the polarization image; calculating, using pixel values of the difference image, a coefficient to be multiplied by at least one of a pixel value of the normal image and a pixel value of the polarization image; and synthesizing the normal image and the polarization image using a pixel value obtained by multiplying the coefficient by the at least one of the pixel value of the normal image and the pixel value of the polarization image to generate a synthesized image, wherein in the calculating, a reflection region that is a pixel region corresponding to a portion exhibiting specular reflection in the object is defined in each of the normal image and the polarization image based on the pixel values of the difference image, and the coefficient to be multiplied by a pixel value of the reflection region is calculated.
