Abstract: Image capturing accuracy is improved while a simple optical system is used. An image capture device includes: a polarizing filter that blocks non-transmitted light that has been in polarized light of an infrared ray radiated from a light source and has not been transmitted through an image capturing target and transmitted light that has been in the polarized light and has been transmitted through the image capturing target without diffusion inside the image capturing target, and transmits transmitted light that has been in the polarized light and has been diffused inside the image capturing target and transmitted therethrough; and an image sensor that receives the light that has been transmitted through the polarizing filter and captures an image of the image capturing target.
