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.

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.

Abstract: An imaging apparatus includes a lens optical system, a color image sensor that includes at least first pixels and second pixels, and a first optical element array disposed between the lens optical system and the color image sensor. In the imaging apparatus, the lens optical system includes optical regions, and the optical regions include a first optical region and a second optical region that differ in terms of at least one selected from the group of spectral transmittance characteristics and transmissive polarization characteristics. The first pixels include respective spectral filters having mutually different spectral transmittance characteristics, and the second pixels include respective spectral filters having at least one type of spectral transmittance characteristics. The first optical element array directs light that has passed through the first optical region to the first pixels and directs light that has passed through the second optical region to the second pixels.

Abstract: A display apparatus includes a first mirror and a half mirror between a display device and a concave mirror. The first mirror reflects emission light emitted from an elongate display surface of the display device, toward the half mirror. The half mirror reflects the light reflected by the first mirror, toward the concave mirror. The concave mirror reflects the light reflected by the half mirror, toward the half mirror. In a top view of the display apparatus, a line passing through a center of the display surface in a longitudinal direction and parallel to the longitudinal direction and a tangent line passing through a center of a reflection surface of the concave mirror in a longitudinal direction and parallel to the longitudinal direction intersect at a predetermined angle.

Abstract: A display device includes: a display element including a display surface on which image is displayed; a first mirror and a second mirror that reflects emission light emitted from the display surface of the display element; and a polarization element. The polarization element is configured to reflect and transmit the emission light from display surface. The emission light from display surface is reflected off polarization element twice and transmitted through polarization element once by a time the emission light is reflected off first mirror and second mirror and exits from display device.

Abstract: A display system includes: a display that emits light corresponding to image information; a half mirror that receives the light emitted, reflects, as reflected light, a first component of the light received, and transmits a second component different from the first component; and a first reflecting mirror having a concave surface that receives and reflects the reflected light toward the half mirror. The half mirror includes a first retardation film, a first support substrate, and a reflective polarizing film stacked in this order from a side on which the light emitted is received. The first retardation film changes a phase of the light received. The first support substrate is light-transmissive. The reflective polarizing film reflects a first polarized component and transmits a second polarized component different from the first polarized component.

Abstract: A display system includes: a display device; a reflection optical system; a housing; and a shield member. The reflection optical system includes at least a last reflective member on which light, emerging from a display screen of the display device, is incident either directly or indirectly. The shield member is held by the housing to assume either a shielding state or an unshielding state. The shielding state is a state where the shield member at least partially cuts off light incident on, or reflected from, the last reflective member. The unshielding state is a state where the shielding state is canceled. The shield member in the shielding state reflects, toward the viewer's eyes, external light impinging on the housing. The housing has a holding structure to hold the shield member, no matter whether the shield member assumes the shielding state or the unshielding state.
