The head-up display includes an imaging position changer configured to change a position of a virtual image between a far visual position far from an observer and a near visual position close to the observer. The imaging position changer inclines the virtual image at the far visual position by a second inclination angle with respect to a perpendicular plane to a reference light beam reaching a center of a viewpoint region in which a viewpoint of the observer is located, to move an upper end thereof in a forward direction of the moving object, and inclines the virtual image at the near visual position by a first inclination angle smaller than the second inclination angle with respect to the perpendicular plane to the reference light beam, to move the upper end in the forward direction of the moving object.

Head-up display

A display system includes an image producing unit, a projection unit and an adjustment unit. The image producing unit has a display surface, and is configured to produce an image on the display surface. The projection unit is configured to project a virtual image to a target space with an output light of the image producing unit. The virtual image corresponds to the image produced by the image producing unit. The display system is configured to change a visual distance between an eye-box and the virtual image. The adjustment unit is configured to adjust brightness of the virtual image according to the visual distance.

Display system, control device, control method, non-transitory computer-readable medium, and movable object

A lens system, an interchangeable lens apparatus, and a camera system each include a front group including a first focus lens group that moves with respect to an image surface in focusing from an infinity in-focus condition to a close-object in-focus condition; a rear group including a second focus lens group that moves with respect to the image surface in focusing, the front group and the rear group being located in order from an object side to an image side; a fixed lens group including at least one positive power lens element, the fixed lens group being located between the front group and the rear group and fixed with respect to the image surface in focusing; and an aperture diaphragm. The positive power lens in the fixed lens group satisfies dPgF&#x3e;0.015 (dPgF is an anomalous dispersibility in a g-line and an F-line of the lens element).
