A virtual image optical system with which a virtual image is formed by introducing light from a display surface to a pupil includes a first reflective surface arranged to reflect the light from the display surface, and a second reflective surface arranged to reflect light from the first reflective surface. An optical path length from the display surface to the second reflective surface is changeable with movement of the first reflective surface, a position of the pupil is changeable with rotation of the second reflective surface in a direction having a component in a direction perpendicular to an optical path of a principal ray incident on the pupil, and an angle formed between a moving direction of the first reflective surface and the principal ray incident on the first reflective surface is 5° or less.

A head up display arrangement for a motor vehicle includes an image source emitting a virtual image based on image data. A mirror is positioned to reflect the virtual image such that the virtual image further reflects off of a windshield of the motor vehicle and is visible to a driver of the vehicle while eyes of the driver are disposed within an eyebox. A driver's input device is coupled to the mirror and changes an angle of reflection of the mirror and thereby changes a vertical level of the eyebox in response to input from the driver. A controller is communicatively coupled to the image source and produces the image data. The controller determines the angle of reflection of the mirror, and adjusts the image data in response to the change in the angle of reflection of the mirror such that a vertical level of the virtual image is unchanged by the change in the angle of reflection of the mirror.

A VR sickness reduction system, a head-mounted display, a VR sickness reduction system, and a program are provided that may reduce VR sickness. An HMD includes a display section positioned in front of a user when the head-mounted display is mounted on the user. A rocking section may rock a head of the user on which the HMD is mounted. An entertainment apparatus causes the display section to display a moving image representing a state viewed from a point of view. The entertainment apparatus controls rocking of the rocking section depending on an acceleration status of the point of view in the moving image displayed on the display section.

A system for augmented reality comprises a helmet and a container body within which a video unit is housed that comprises a device for acquiring images of a real scene and a display device for displaying at least the aforementioned images. A support body is, furthermore, provided configured to engage the container body to the helmet. The container body and the support body are provided with respective first and second engagement members configured to selectively and alternatively removably engage the container body to the support body in a first engagement position, in which the device for acquiring images is arranged to acquire images with a first predetermined field of view and the display device is positioned within the field of view of the user, and at least a second engagement position, in which the device for acquiring images is arranged to acquire images with a second predetermined field of view.

A head-up display device includes a display element, a beam splitter, a movable mirror, first and second mirrors, and a movable unit. The display element emits light to form a display image. The beam splitter being an optical member that reflects light or through which light is transmitted, reflects light emitted from the display element. The movable mirror reflects light reflected off the beam splitter. The first and second mirrors that reflect light movable mirror, or through which the light transmitted through the beam splitter is transmitted, project a virtual image. The movable unit adjusts a distance between the movable mirror and the beam splitter to adjust a projection distance of the virtual image.

A pair of augmented reality glasses including a projection device and a waveguide is provided. The projection device is configured to provide a collimated beam. The waveguide has a plurality of free form surfaces. Distances between each free form surface and the projection device are different from each other. The collimated beam progresses to and reflects off these free form surfaces in sequence, and then enters eyes of the user.

A flexure guidance system may be provided for controlling movement of an optical subassembly and/or a connected combiner lens. For instance, the flexure guidance system may include a distal end piece, a proximal end piece, and multiple wire flexures that link the distal end piece to the proximal end piece. The linking wire flexures may be spaced to form an interior cavity between the distal end piece and the proximal end piece. This interior cavity may house various electronic components. One or more actuators in the system may move the electronic components according to input signals along different axes of movement provided by the wire flexures. Various other methods, systems, and computer-readable media are also disclosed.

The present invention relates to a vehicle display device comprising: a display unit comprising a transparent flexible display disposed in a state of being rolled around a certain axis; a driving unit for adjusting the length of a region, of the transparent flexible display, exposed inside the vehicle; and a processor for controlling the driving unit and controlling the display of a picture on the transparent flexible display.

An image rendering apparatus includes a light source unit, an optical scanner, a scanner control unit configured to control a frequency for the optical scanner to scan the laser light in the main scanning direction, and a light source driving unit. The scanner control unit multiplies the frequency by n and the light source driving unit changes time intervals at which pixels are rendered on scanning lines in the main scanning direction to 1/nth and controls the light source unit in such a way that the light source unit renders a plurality of pixels corresponding to one scanning line at least once during n scans in the main scanning direction and in such a way that the light source unit will not render pixels on scanning line(s) other than the scanning lines on which the pixels have been rendered.

The subject of the invention is a device for generating images (10) for automotive vehicle head-up display (100), comprising a liquid crystal screen (12) and a back-lighting device (14), said back-lighting device (14) comprising: at least one light-emitting diode (16), a housing (28; 29) surrounding the space lying between the at least one light-emitting diode (16) and the liquid crystal screen (12), characterized in that said housing (28; 29) is bent, the device for generating images (10) furthermore comprising a reflecting surface (31; 32) arranged in a bent portion (28c; 29c) of the housing (28; 29) and oriented in such a way as to reflect the light emitted by the at least one light-emitting diode (16) in the direction of the screen (12). The invention also relates to a head-up display (100).
