Abstract: The image processing method includes a luminance value information obtaining step of obtaining effective radiance values from a subject, and an image generating step of generating a picture image as a set of unit regions each of which has a luminance value obtained by at least partially removing a regular reflection light component on a surface of the subject from the effective radiance values.

Abstract: An influence of a reflected image included in an infrared light image is reduced. An image pickup unit (20) includes an image pickup element (21) including an infrared light image-image pickup region (21a) and a visible light image-image pickup region (21b) and a polarizing filter (25) in which a plurality of polarizing units including a plurality of polarizing elements (25a to 25d) having principal axes different from each other are associated with a plurality of pixels forming the infrared light image-image pickup region and are arranged two-dimensionally.
