An autostereogram is a single-image stereogram (SIS), designed to create the visual illusion of a three-dimensional (3D) scene from a two-dimensional image. In order to perceive 3D shapes in these autostereograms, one must overcome the normally automatic coordination between accommodation (focus) and horizontal vergence (angle of one's eyes). The illusion is one of depth perception and involves stereopsis: depth perception arising from the different perspective each eye has of a three-dimensional scene, called binocular parallax.

  • An autostereogram is a single-image stereogram (SIS), designed to create the visual illusion of a three-dimensional (3D) scene from a two-dimensional image. In order to perceive 3D shapes in these autostereograms, one must overcome the normally automatic coordination between accommodation (focus) and horizontal vergence (angle of one's eyes). The illusion is one of depth perception and involves stereopsis: depth perception arising from the different perspective each eye has of a three-dimensional scene, called binocular parallax. The simplest type of autostereogram consists of horizontally repeating patterns (often separate images) and is known as a wallpaper autostereogram. When viewed with proper convergence, the repeating patterns appear to float above or below the background. The well-known Magic Eye books feature another type of autostereogram called a random dot autostereogram. One such autostereogram is illustrated above right. In this type of autostereogram, every pixel in the image is computed from a pattern strip and a depth map. A hidden 3D scene emerges when the image is viewed with the correct convergence. Autostereograms are similar to normal stereograms except they are viewed without a stereoscope. A stereoscope presents 2D images of the same object from slightly different angles to the left eye and the right eye, allowing us to reconstruct the original object via binocular disparity. When viewed with the proper vergence, an autostereogram does the same, the binocular disparity existing in adjacent parts of the repeating 2D patterns. There are two ways an autostereogram can be viewed: wall-eyed and cross-eyed. Most autostereograms (including those in this article) are designed to be viewed in only one way, which is usually wall-eyed. Wall-eyed viewing requires that the two eyes adopt a relatively parallel angle, while cross-eyed viewing requires a relatively convergent angle. An image designed for wall-eyed viewing if viewed correctly will appear to pop out of the background, while if viewed cross-eyed it will instead appear as a cut-out behind the background and may be difficult to bring entirely into focus.

  • Un autostéréogramme est un stéréogramme constitué d'une seule image qui donne l'illusion d'une scène en trois dimensions (3D) à partir d'une image en deux dimensions (2D). Afin de percevoir des formes en 3D grâce aux autostéréogrammes, le cerveau doit faire un effort oculaire de convergence et de mise au point dissocié de l'accommodation. L'autostéréogramme le plus simple consiste en une série de motifs répétée horizontalement. Quand on le regarde avec la bonne convergence, on a l'impression que les motifs flottent au-dessus ou en dessous de l'image de base. Dans le livre Magic Eye (en), on peut trouver une autre sorte d'autostéréogramme composé d'une multitude de petits points. L'animation en haut à droite par exemple en est un. Chaque pixel de l'image est calculé par un ordinateur. Dans tous les cas, avec la bonne convergence des yeux on doit voir apparaître une forme en 3D. À la différence des stéréogrammes classiques, les autostéréogrammes peuvent être vus sans stéréoscope. Un stéréoscope présente deux images en 2D d'un objet prises sous un angle légèrement différent, afin que le cerveau ait une vue 3D de cet objet. Dans le cas de l'autostéréogramme, le cerveau reçoit deux motifs en 2D dans chaque œil, mais n'arrive pas à les faire coïncider correctement. Il assemble les motifs en un objet virtuel à cause des mauvais angles de parallaxe, et l'objet virtuel n'est par conséquent pas sur le même plan que l'image de l'autostéréogramme. Il y a deux manières de visionner un autostéréogramme : en gardant les yeux relativement parallèles, ou en les faisant converger. La plupart des autostéréogrammes sont conçus pour être vus selon la première façon. (fr)
  • L'autostereogramma, è uno stereogramma a singola immagine (SIS: Single Image Stereogram, in inglese), realizzato per creare una illusione ottica tridimensionale da un'immagine bidimensionale, nel cervello umano. Al fine di percepire una forma tridimensionale in un autostereogramma, gli occhi devono superare di norma il coordinamento automatico tra messa a fuoco e convergenza. Esistono varie tipologie di autostereogramma che comprendono: wallpaper autostereogram (autostereogramma "carta da parati"), Autostereogramma SIS, Autostereogramma TUT, Autostereogramma SIRDS, ecc. In italiano questo tipo di immagine viene talvolta impropriamente detta anche stereogramma, tuttavia questo utilizzo è errato poiché il termine definisce tutti i tipi di immagine piana atta a produrre un effetto di profondità, non soltanto l'autostereogramma.

  • Een autostereogram is een stereogram, en geeft de optische illusie van een driedimensionaal beeld, op basis van een gewone tweedimensionale afbeelding. Om dit soort optische illusie te kunnen zien, is een zekere oefening vereist. Een belangrijk verschil met gewone stereogrammen is dat men voor een autostereogram geen extra kijker of stereoscoop nodig heeft. (nl)
  • Autostereogram – jednoobrazkowa odmiana stereogramu, polegająca na stymulowaniu mózgu do odebrania dwuwymiarowego obrazu jako trójwymiarowego. W przeciwieństwie do stereogramów, autostereogramy nie wymagają użycia specjalnego sprzętu optycznego, by móc je oglądać. Autostereogramy powstały w 1979 roku, stworzone przez Christophera Tylera z Smith-Kettlewell Institute. (pl)
  • Um autostereograma é uma imagem estereográfica simples (SIS), desenhada para criar uma ilusão de ótica de uma cena 3d a partir de uma imagem 2d, fazendo com que o cérebro humano a partir da acomodação visual, perceba a imagem em 3D automaticamente. O tipo mais simples de autostereograma consiste em padrões horizontais iguais e é conhecido como um autoestereograma papel-de-fundo. Quando visto com a convergência adequada, os padrões repetitivos parecem flutuar acima ou abaixo do fundo. A série de livros Magic Eye apresentam outro tipo de autostereograma chamado autostereograma de pontos aleatôrios. Um desses autostereogramas está ilustrado à direita. Nesse tipo de autostereogramas,cada pixel nessa imagem é computada a partir de uma tira padrão e um mapa de profundidade. Normalmente, uma cena 3D escondida emerge quando a imagem é vista com a convergência correta. Os autostereogramas são parecidos com stereogramas normais exceto que são vistos sem um estereoscópio. Um stereoscópio apresenta imagens 2D do mesmo objeto a partir de diferentes ângulos para o olho esquerdo e o olho direito, fazendo com que o cérebro reconstrua o objeto original a partir de divergência binocular. Com um autostereograma, o cérebro recebe padrões 2D repetitivos através dos dois olhos, mas não consegue alinhálos corretamente. Ele pareja dois padrões adjecentes para um objeto virtual baseado ângulos paralelos errados, para depois colocar o objeto virtual numa profundidade diferente do autostereograma. Existe duas maneiras de ver um autostereograma: a maneira wall-eye e a maneira cross-eye. A maioria dos autostereogramas (incluindo os contidos neste artigo) são feitos para ser vistos apenas numa maneira, que normalmente é a maneira wall-eye. Para ver autostereogramas no gênero wall-eye requere que os dois olhos adotem um ângulo relativamente paralelo, enquanto cross-eye requer um ângulo relativamente convergente. (pt)
