Abstract: In image capturing processor in one embodiment comprises: an image capturing section including an image sensor that captures a polarization image of an object being illuminated with an illuminating light beam; and an image processing section. The image processing section has: a light intensity image generator which generates a light intensity image based on the output of the image sensor; a polarization degree image generator which generates a polarization degree image by calculating the degree of polarization on a pixel-by-pixel basis; a retouching section which generates a retouched polarization image by enhancing the degree of polarization of the polarization degree image at depressions on a micro-geometric surface of the object and by correcting at least one of its hue, saturation and value; and an image synthesizing section which synthesizes the retouched polarization image and the light intensity image together.

Abstract: A polarization image sensor includes: photodiodes arranged on an image capturing plane; a color mosaic filter in which color filters in multiple different colors are arranged to face the photodiodes; an optical low-pass filter which covers the color mosaic filter; and polarization optical elements located closer to a light source than the optical low-pass filter is. Each polarization optical element covers an associated one of the photodiodes and makes light which is polarized in a predetermined direction in a plane that is parallel to the image capturing plane incident onto the optical low-pass filter. The color filters are arranged so that light that has passed through polarization optical elements is transmitted through an associated one of the color filters in a single color. Each color filter covers multiple photodiodes.
