CONT

Smart eyewear is defined as eyewear incorporating a near-to-eye display. As used herein, near-to-eye display means a display, device, or system, such as a retinal projector, virtual retinal display, visualization element, head-mounted display, heads-up display, or other near-to-eye system, typically worn on the head of a user that generates an image near the eye. In a smart eyewear configuration, a display device is often mounted adjacent to an edge of each of the wearer's eyes and an image is typically displayed in the center of each lens. The location of the displayed image, therefore, forces the wearer to gaze in a direction to view the image generated by the display. Typically positioned near the user's eye, the display is aligned to the central region of the user's field of view to allow review of the displayed information with little or no head movement. This enables the user to view the display while also viewing the area outside the central region and interacting with the surrounding environment. In another embodiment, the displayed image is aligned to a region other than the central region of the user's field of view.

CONT

Near-eye display devices are configured to present images to a user via a display that is positioned close to the user’s eyes. For example, a head-mounted augmented reality display device may be worn on a user’s head to position a near-eye display directly in front of a user’s eyes. A near-eye display may be at least partially see-through to allow a user to view a real-world background in combination with displayed virtual objects. This may allow virtual objects to be displayed such that the virtual objects appear to exist within the real-world environment.

CONT

The technology provides one or more embodiments of a near-eye display (NED) device system. An embodiment of a NED device system comprises a near-eye display device including a near-eye support structure and a near-eye display (NED) supported by the near-eye support structure and having a display field of view. The NED system further comprises an image generation unit supported by the near-eye support structure which outputs image data which is optically coupled to the near-eye display (NED).

OBS

near-to-eye display; near-eye display: data validated by Canadian subject-field experts from École Polytechnique de Montréal, MasterpieceVR and McGill University.

Lentille additionnelle. Bonnette. Lentille fixée devant un objectif pour en modifier la focale. On l'utilise, en général, pour photographier à une distance ou à une échelle que ne permet pas l'objectif dont on dispose. Les bonnettes négatives allongent la focale et donnent la possibilité de photographier à une échelle plus grande. Les bonnettes positives raccourcissent la focale et la distance au sujet peut ainsi être réduite.

  • Photography
CONT

... The large body [of the camera] accommodates an impressively long 12X zoom... The lens also includes an optical image stabilizer, which moves an element of the lens to keep images steady(other cameras include electronic image stabilization, which helps the camera compensate for movement after the image is taken; optical stabilization tends to be more effective). This worked extremely well, compensating for camera shake on longer exposures and when we used the zoom. It's no substitute for using a tripod, but it does keep images sharp.

French

Domaine(s)
  • Photographie
CONT

Mouvement brusque de la main, coup de vent, lumière insuffisante, il existe une multitude de raisons pour rendre floue n'importe quelle photo. Or, à moins de toujours avoir sur soi un trépied [...] et de ne prendre des photos qu'en milieu parfaitement éclairé, le seul moyen de réussir ses clichés est de disposer d'un appareil à stabilisateur optique intégré. Ce système compense aussi bien les moindres mouvements de l'appareil que les longs temps d'obturation lorsque la lumière est trop faible. Les stabilisateurs optiques sont la plupart du temps composés d'une succession de lentilles motorisées correctrices. Ils sont les garants de photos parfaitement nettes, surtout lors de l'utilisation du zoom, qui amplifie immédiatement le moindre mouvement de l'appareil.

Subject field(s)
  • Audiovisual Techniques and Equipment

CONT

Lens stabilization is a feature that compensates, to some degree, for [digital video] camera shake. Electronic stabilization works at the chip level, by recording only a large but incomplete portion of the total image created by the chip. So when the camera shakes in one direction, the image portion recorded moves proportionately in the opposite direction, cancelling out the camera movement prism. When the image moves off the center axis, the front element of the prism tilts to re-center it a the chip.

Key term(s)

In facsimile, the diode sensor array uses a stationary configuration of tiny photodiodes arranged in a matrix that equals in width one lateral scan line of a document. An original is rollerfed from a flatbed tray and passes by the sensor array one line at a time. Light is reflected from each line and focused through a lens onto the face of the photodiode array. Each diode acts as an independent photosensor in converting a small picture element into part of the total electrical signal for a scan line.

The S512 with its PbS photo detector has a linear response from low to medium brightness flames, that is, no distortion of flame signal occurs with regard to any amplifier saturation or AGC action(compression).
