Abstract
An image processing apparatus includes a first processing task configured to acquire surface normal information of an object, a second processing task configured to acquire a plurality of first images acquired by capturing the object while changing a polarization angle of light from the object, a third processing task configured to acquire polarization information of the object, and a fourth processing task configured to generate a second image in which an illumination state of the object is different from that of each first image. The third processing task acquires light intensity information that changes according to the polarization angle, using the first images. The fourth processing task extracts a partial area of the first images using the surface normal information, and generates the second image using the partial area and the light intensity information.
