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.

Abstract: A display system of one aspect according to the present disclosure includes: a display unit; a first optical member; and a second optical member. The display unit includes a display surface for displaying an image. The first optical member includes a first reflective surface for reflecting rays of light constituting the image. The second optical member includes a second reflective surface for reflecting rays of light reflected from the first reflective surface to form a virtual image in a target space. An angle of view in a length direction of an available area for display of the virtual image with regard to a point of view position for the virtual image is denoted by θ [deg]. A length of the display surface is denoted by W [mm]. W is equal to or greater than a prescribed value given by 12.0×θ−26.6. θ is equal to or greater than 8.0.

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.

Abstract: A display apparatus includes a housing and at least one mirror. The housing can be detachably mounted on a display and includes an entrance that allows light emitted from the display to enter the interior of the housing with the housing mounted on the display and an exit that allows the light having entered the interior of the housing through the entrance to exit to the exterior of the housing. The at least one mirror reflects the light having entered the interior of the housing through the entrance to the exit.

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.
