An active shutter 3D system (a.k.a. alternate frame sequencing, alternate image, AI, alternating field, field sequential or eclipse method) is a technique of displaying stereoscopic 3D images. It works by only presenting the image intended for the left eye while blocking the right eye's view, then presenting the right-eye image while blocking the left eye, and repeating this so rapidly that the interruptions do not interfere with the perceived fusion of the two images into a single 3D image.

  • Ein Shutter-3D-System benötigt zum Sehen von 3D-Bildern Shutterbrillen (auch LCD-Shutterbrillen). Diese speziellen Brillen haben Gläser, die aus zwei Flüssigkristallflächen bestehen (je eine für das linke und rechte Auge), die elektronisch zwischen durchlässig und undurchlässig umgeschaltet werden können. Damit lässt sich wahlweise das linke oder das rechte Auge abdunkeln. Dazu wird abwechselnd das linke und rechte Bild auf einem Monitor, einem Fernsehgerät oder auf einer Leinwand angezeigt. Von der Brille wird dabei synchron nur das passende Bild zum entsprechenden Auge durchgelassen. Dies ermöglicht ein stereoskopisches Sehen, beispielsweise für die Wiedergabe von 3D-Filmen. (de)
  • Alternate Image (A.I., in inglese "immagine alternata"), anche conosciuta come shutter glasses ("occhiali con otturatore") o alternate-frame sequencing ("sequenza di frame alternati"), che può essere resa in italiano come otturatori alternati, è una tecnica di visione stereoscopica applicata a cinema tridimensionale, televisione e videogiochi, atta a ottenere una illusione di tridimensionalità da immagini stereoscopiche parallele proiettate in sequenza alternata.

  • Os shutter glasses são uma espécie de óculos composto por duas lentes que são, na verdade, duas telas de LCD que "se fecham como persianas", enviando sinais remotos do emissor de um aparelho de TV para os óculos e vice-versa, ativando as telas de LCD de acordo com a imagem processada e criando, assim, imagens em 3 dimensões.

  • Un sistema actiu de l'obturador 3D (seqüenciació de quadres alterns, imatge alternativa, AI, camp altern, camp seqüencial o eclipsi) és una tècnica de visualització d'imatges estereoscòpiques en 3D. Funciona només presentant la imatge destinada a l'ull esquerre mentre bloqueja la vista de l'ull dret, i després presenta la imatge de l'ull dret mentre bloqueja l'ull esquerre i repetint aquest procés tan ràpidament que les interrupcions no interfereixen amb la fusió percebuda de les dues les imatges en una sola imatge en 3D.

  • Les lunettes à obturation LC (Liquid Crystal) permettent de visualiser des images en 3 dimensions à partir de deux images bidimensionnelles affichées sur un écran plat. Chaque verre possède un système d'obturation à valve optique qui le rend opaque ou transparent suivant le signal électrique qu'on applique aux cristaux liquides qui composent le verre en question. Les signaux contrôlant chaque verre sont en opposition de phases et synchronisés avec l'alternance des images droite et gauche par le projecteur, si bien que l'œil droit ne voit que les images "droites" et l'œil gauche que les images "gauche". La bonne synchronisation entre les lunettes et le projecteur est primordiale car contrairement aux lunettes 3D à polarisation ou aux lunettes 3D rouge/cyan (anaglyphe) les images gauche et d (fr)
  • 액정 셔터 안경(liquid crystal shutter glasses) 또는 능동식 셔터 안경(active shutter glasses)은 HMD 등의 가상현실 구현 장치의 한 가지이다. 개인 및 전문가용으로 적합하고 구입할 수 있는 HMD 또는 자동 스테레오 디스플레이어가 널리 사용되기 위해서는 어느 정도 시간이 필요하다. 그 사이에 좀 더 기술의 운용이 수월하고 운반이 용이한 셔터 안경이 디스플레이 데스크탑으로의 가시화의 도구로서 일반화되고 있는 것으로 보인다. 셔터 안경은 LCD 안경을 이용하여 시야를 차단시켜 영상을 분리한다. 시간의 순서에 따라 좌우 영상을 번갈아 주사하기 때문에 이러한 방식을 시분할 입체 영상이라고 부른다. 셔터 안경은 약 9V 이상에서 동작하며 이 전압이 인가되면 안경이 검게 변해 시야를 가리게 된다. 좌측 영상이 화면에 주사될 때는 우측 안경에 전압을 인가하여 좌측 눈에만 영상을 보이게 만들 수 있으며 반대로 우측 영상이 화면에 주사될 때는 좌측 안경에 전압을 인가하여 우측 눈에만 영상을 보이게 만들 수 있다.
