Image pickup system

摘要

An imaging system according to the present disclosure includes: a polarized light source which emits illuminating light including a component of light that oscillates parallel to a first polarization axis; an image capturing unit IP which is configured to get simultaneously first, second, third and fourth pieces of image information S101, S102, S104 including pieces of information about light beams that fall within first, second, third and fourth wavelength ranges, respectively, based on light beams that have returned at the same point in time from an object that is irradiated with the illuminating light, the light beam falling within the fourth wavelength range having been emitted from the polarized light source and reflected from the object, oscillating parallel to a second polarization axis that is different from the first polarization axis, and belonging to the same wavelength range as the component of the illuminating light.

1. An imaging system comprising:
a polarized light source which emits illuminating light including a component of light that oscillates parallel to a first polarization axis; an image capturing unit which is configured to get, based on light beams that have returned at the same point in time from an object that is irradiated with the illuminating light, a first piece of image information including information about light beam that fall within a first wavelength range, a second piece of image information including information about light beam that fall within a second wavelength range, a third piece of image information including information about light beam that fall within a third wavelength range and a fourth piece of image information including information about light beam that fall within a fourth wavelength range, the light beam falling within the fourth wavelength range having been emitted from the polarized light source and reflected from the object, oscillating parallel to a second polarization axis that is different from the first polarization axis, and belonging to the same wavelength range as the component of the illuminating light; a first arithmetic processing section which is configured to generate a first piece of color image information based on the first, second and third pieces of image information; and a second arithmetic processing section which is configured to generate a second piece of color image information by synthesizing each of the first, second and third pieces of image information with the fourth piece of image information.
