Definitions

  • the present invention relates to a method, system and apparatus for producing three-dimensional (3D) imagery.
  • the present invention also relates to a computer program product including a computer readable medium having recorded thereon a computer program for producing three-dimensional (3D) imagery.
  • Stereoscopy may also be referred to as stereoscopic or 3D imaging.
  • Stereoscopic imaging creates or enhances the perception of depth in an image by presenting two offset images (i.e., two perspective views) of an object separately to the left and right eye of the viewer.
  • the two-dimensional (2D) offset images are then combined in the brain of the viewer to give the perception of 3D depth.
  • conventional stereoscopy requires an object to be obtained and then two offset images of the object to be captured.
  • Conventional stereoscopy does not allow three dimensional images of the object to be produced from a single two-dimensional image of the object.
  • a processor coupled to said memory for executing said computer program, said computer program comprising instructions for:
  • the second distorted image version being generated from another of the two spaced apart angles of view about the common centre of the two-dimensional image; and displaying the first and second distorted versions of the two-dimensional image on a screen, wherein the first and second distorted images are observed as a three dimensional image of the object when the displayed first and second distorted versions are observed using a view separating system.
  • an apparatus for producing three dimensional imagery comprising:
  • first and second distorted versions of the two-dimensional image on a screen, wherein the first and second distorted images are observed as a three dimensional image of the object when the displayed first and second distorted versions are observed using a view separating system.
  • Fig. 2B shows two whole offset images of Fig. 2A displayed vertically one above the other on the screen;
  • producing means acquisition, generation or construction for display upon a screen, or transmission for display, or broadcasting for display.
  • producing may mean acquisition, generation, or construction for storage and later display, transmission, broadcasting or projection.
  • Fig. 4B is a detailed schematic block diagram of the processor 405 and a "memory" 434.
  • the memory 434 represents a logical aggregation of all the memory modules (including the HDD 409 and semiconductor memory 406) that can be accessed by the computer module 401 in Fig. 4 A.
  • the operating system 453 manages the memory 434 (409, 406) to ensure that each process or application running on the computer module 401 has sufficient memory in which to execute without colliding with memory allocated to another process. Furthermore, the different types of memory available in the system 400 of Fig. 4A must be used properly so that each process can run effectively. Accordingly, the aggregated memory 434 is not intended to illustrate how particular segments of memory are allocated (unless otherwise stated), but rather to provide a general view of the memory accessible by the computer system 400 and how such is used.
  • the method 300 will be described with reference to two offset distorted images each representing a different perspective view of an object. However, the method 300 is equally applicable to implementation, where multiple left and right perspective views are generated.
  • the left and right offset distorted images 600 and 700 stored within the memory 406 at steps 303 and 305 may subsequently be transferred to any other storage media such as computer readable storage media as defined above, including a compact disc (CD), a digital video disc (DVD), or the like.
  • the left and right offset distorted images 600 and 700 may also be transmitted over the network 420 to a remote server or the like, for example, connected to the network 420, before being displayed on the screen of a suitable display device.
  • the left and right offset distorted images 600 and 700 may also be transmitted over conventional analog television networks or digital television networks in an analog or digital form, respectively, for display on the screen of any suitable display device.
  • the left and right offset distorted images may be generated by the processor 405 at steps 303 and 305 using a displacement map where pixels of an active layer of the 2D image may be displaced according to the gradient slope in the displacement map.
  • a displacement map pixels corresponding to solid areas are not displaced; the higher the slope, the higher the displacement.

Abstract

L'invention concerne un procédé permettant de produire une imagerie en trois dimensions. Une première version déformée (600) d'une image bidimensionnelle d'un objet est générée, la première version de l'image transformée (600) étant générée à partir d'un angle parmi deux angles de vue espacés l'un de l'autre autour d'un centre commun de l'image bidimensionnelle. Une seconde version déformée (700) de l'image bidimensionnelle est générée, la seconde version de l'image déformée (700) étant générée à partir de l'autre des deux angles de vue espacés l'un de l'autre autour du centre commun de l'image bidimensionnelle. Les première et seconde versions déformées de l'image bidimensionnelle sont affichées sur un écran. Les première et seconde images déformées sont observées sous la forme d'une image tridimensionnelle de l'objet lorsque les première et seconde versions déformées affichées sont observées au moyen d'un système de séparation de vues.
