A display control unit (4) causes a display unit (5a) to display a stereoscopic image in which an image, in which a right-eye pixel (201Rpix) and a left-eye pixel (201Lpix) are periodically arrayed in the horizontal direction, is arrayed in every two rows in the vertical direction. An image separating unit (5b) separates the stereoscopic image into right-eye pixels (201aR) and left-eye pixels (201aL) at a separation angle 0 and also into right-eye pixels (201bR) and left-eye pixels (201bL) at a separation angle 1.

A head-up display device displays a near virtual image and a far virtual image formed at different positions. The head-up display device includes an extension optical element, in addition to a first display surface that luminously displays a near display image and a second display surface that luminously displays a far display image. The extension optical element includes a reflective surface disposed on an optical path of light of the far display image. The extension optical element makes a far optical path distance of the far display image longer than a near optical path distance of the near display image by reflection of light by the reflective surface. The extension optical element has a transmission part that transmits light of the near display image in an area overlapping an optical path of light of the near display image.

A hybrid augmented reality head-up display system for displaying graphics upon a windscreen of a vehicle includes a windscreen having a transparent substrate including light emitting particles dispersed within, a primary graphic projection device for generating a first set of images upon the windscreen of the vehicle based on visible light, and a secondary graphic projection device for generating a second set of images upon a secondary area the windscreen of the vehicle based on an excitation light. The first set of images are displayed upon a primary area of the windscreen. The light emitting particles in the windscreen emit visible light in response to absorbing the excitation light. The first set of images displayed upon the primary area of the windscreen cooperate with the second set of images displayed upon the secondary area of the windscreen to create an edge-to-edge augmented reality view.

There is provided ahead-up display in a vehicle arranged to display a picture, the head-up display comprises a first optical sub-system disposed in an upper region of the windscreen and a second optical sub-system disposed underneath the dashboard of the vehicle proximate a lower region of the windscreen. The first optical sub-system is arranged to output a light field. The first optical sub-system comprises a light source and a spatial light modulator. The light source is arranged to emit light. The spatial light modulator is arranged to receive the light from the light source and spatially-modulated the light in accordance with a computer-generated hologram displayed on the spatial light modulator. The second optical sub-system is arranged to receive the light field from the first optical sub-system and project the light field onto a windscreen of the vehicle to form a virtual image on the windscreen.
