Abstract: A display system includes: a display element that includes a display surface through which light showing an image is emitted; a concave mirror that reflects the light emitted through the display surface of the display element; and an optical element that includes a wave plate and a transmissive polarizing plate that is a polarizing element, the optical element facing the concave mirror. The concave mirror and the optical element are each provided separately from the display element. The optical element (i) transmits reflected light resulting from the light emitted through the display surface of the display element being reflected by the concave mirror, and (ii) reflects light from outside off a surface of the optical element, the surface facing the concave mirror, the light from the outside entering the optical element from a side through which the reflected light exits, and being reflected by the concave mirror.

Abstract: A tangent line, described next, is, in top view, parallel to a straight line extending in a width direction of the display surface in a range in which the attitude can be changed. The tangent line is present on a plane orthogonal to the up-down direction of the automobile, and contacts a center of the final reflective surface. In top view, of an angle formed by a straight line connecting a center of the final reflective surface with a center of the display surface and the tangent line of the final reflective surface, a supplementary angle which is supplementary to an angle that is on a rear side of the automobile and that is on a side where the observer is present is an acute angle of less than 90 degrees.

Abstract: A display system includes a display device, a first mirror, and a second mirror. The display device includes a display surface that displays a first image. Light emitted by the display device is incident directly or indirectly on the first mirror. The first mirror reflects the light incident. The light reflected by the first mirror is directly or indirectly incident on the second mirror. The second mirror reflects, toward an eye-box, the light incident. The light reflected by the second mirror enters an eye of an observer present within the eye-box to display, on the eye of the observer, a second image based on the first image. The first mirror is a Fresnel mirror.

Abstract: An imaging optical system includes a lens system including a first lens, a second lens, a third lens, and a fourth lens, which are arranged in this order such that the first lens is located closest to an object, out of these four lenses and that the fourth lens is located closest to an image formed, out of these four lenses. One surface, facing the object, of the first lens has negative power. The other surface, facing the image, of the first lens has negative power as well.

Abstract: A display system includes a display unit, a housing, and a reflecting optical system. The display unit displays an image based on a captured image. The housing includes a housing room that houses the display unit and the reflecting optical system. The reflecting optical system reflects the image displayed on the display unit, thereby outputting the reflected image through an opening of the housing to the outside of the housing.

Abstract: An embodiment of an image processing apparatus includes: an illuminating section which sequentially irradiates an object with a first and second illuminating light beams polarized in different directions. The section emits the polarized light beams sequentially so that the wavelength ranges of the light beams do not overlap with each other. The apparatus further includes: a polarization image sensor; a polarization mosaic processing section which obtains a first polarization image while the object is being irradiated with the first illuminating light beam and a second polarization image while the object is being irradiated with the second illuminating light beam; a depressed area detecting section which detects a depressed area on the surface of the object based on the polarization images; and an image forming section which forms an image representing the depressed area in an enhanced form.
