  • Publication number: 20200314303
    Abstract: A camera system includes an image sensor, a wavelength filter, and an imaging optical system. The image sensor has an image capturing plane. The imaging optical system is configured to have light coming from a subject passed through the wavelength filter and imaged on the image capturing plane. The wavelength filter has a perpendicularly incident region and an obliquely incident region. On the perpendicularly incident region, a principal ray, which has passed through the imaging optical system, is incident perpendicularly. On the obliquely incident region, a principal ray, which has passed through the imaging optical system, is incident obliquely. The image sensor has sensitivity to a light ray having a predetermined wavelength. The light ray having the predetermined wavelength is transmitted at a higher transmittance through at least a part of the obliquely incident region than through the perpendicularly incident region.

  • Publication number: 20200070729
    Abstract: A display system according to the present disclosure includes at least a first reflective surface and a second reflective surface on an optical path leading from a display device to a last reflective surface. The first reflective surface reflects a light beam emerging from the display device toward the second reflective surface. The second reflective surface reflects, toward the last reflective surface, the light beam reflected from the first reflective surface. The light beam emerging from the display device travels along a first optical path leading from a display screen of the display device to the first reflective surface and then travels along a second optical path leading from the second reflective surface to the last reflective surface. The first optical path and the second optical path intersect with each other before the light beam impinges on the last reflective surface.

  • Publication number: 20190299858
    Abstract: Disclosed herein is a display system including an image producing unit and an optical system part. The image producing unit produces an image on a display screen by letting a light beam, which eventually forms a virtual image based on the image produced, emerge from the display screen. The optical system part forms a left-eye image and a right-eye image on a user's left and right eyes, respectively, and thereby projects the virtual image toward a user's left and right eyes by reflecting and/or refracting the light beam emerging from the display screen. The optical system part has an image distortion generation factor to make an image distortion of the left-eye image different from an image distortion of the right-eye image.
