Abstract
A three-dimensional image display system, based on a novel depth concept referred to as Double-D-Depth, includes a first display device (3) and at least a second display device (4) which, viewed along the system axis (9-91), are offset with respect to each other and are each intended to partially display the same two-dimensional image of a scene, while parameters which are relevant to depth representation are included in the form of an additional dedicated intensity gradation in at least one of the displayed images, and all images, together with the axial distance (.quadrature.L) in between, evoke a depth effect with a viewer (10).
Claims24
A three-dimensional image display system comprising:
- a system axis which extends from a light-generating element to an observation window;
- at least two image display devices displaying images at different positions along said system axis, said images having a transparency attribute;
- a control circuit;
- each image display device partially generating and displaying the same two-dimensional image of a three-dimensional scene;
- and
- a dedicated intensity gradation disposed in at least one of the displayed images, said intensity gradation including parameters relevant to depth representation, said parameters including at least one of depth position of scene components, height of scene components, thickness of scene components and the distance between scene components;
- said dedicated intensity gradation affecting said transparency attribute;
- wherein all displayed images generated by said image display devices together and in combination with the axial distance between the image display devices evoke a depth effect with a viewer.
A three-dimensional image display system comprising:
- a system axis which extends from a light-generating element to an observation window;
- at least two image display devices which are congruently aligned with each other and placed at different positions along the system axis;
- a control circuit;
- each image display device partially generating and displaying the same two-dimensional image of a three-dimensional scene;
- the distance between the image display devices, viewed from the observation window, being equal to a fraction f of the diagonal of the image surface areas of the image display devices, in which it holds for f that:
- ##EQU5## and a dedicated intensity gradation disposed in at least one of the displayed images, said intensity gradation including parameters relevant to depth representation, said parameters including at least one of depth position of scene components, height of scene components, thickness of scene components and the distance between scene components;
- wherein all displayed images together and in combination with the axial distance between the image display devices evoke a depth effect with a viewer.
A method for displaying a three-dimensional image having scene components and a transparency attribute, said method comprising:
- determining a dedicated intensity gradation which affects said transparency attribute;
- and
- displaying said scene components and said dedicated intensity gradation on at least two image display devices, thereby creating the effect of depth in said image.
A three-dimensional image display system comprising:
- a system axis;
- at least two image display devices displaying respective images at different positions along the system axis, each image display device partially generating and displaying the same two-dimensional image of a three-dimensional scene, each image having a transparency attribute;
- and
- a dedicated intensity gradation disposed in at least one of the displayed images;
- said dedicated intensity gradation affecting said transparency attribute;
- wherein all displayed images generated by said image display devices together and in combination with an axial distance between the image display devices evoke a depth effect with a viewer.
