Definitions
- the invention relates to arrangements for three-dimensional representation, in particular to those in which one or more viewers can experience a spatial impression without aids such as glasses.
- At least one wavelength filter array which specifies directions of propagation for light of different picture elements.
- Said image elements represent partial image information of several views of a scene or of an object. Due to the predetermined directions of light propagation, the eyes of an observer predominantly see a first and a second selection of views, thereby creating a spatial impression on the observer.
- the invention is based on the object of developing arrangements of the type mentioned in such a way that improved image quality is achieved.
- an arrangement for spatial representation comprising:
- At least one filter array arranged in front of or behind the image display device in the viewing direction, consisting of a plurality of in a grid
- the filter elements ß pq depending on their transmission wavelength range and / or transmittance ⁇ b are arranged according to the following function on the grid of rows q and columns p
- b an integer which defines one of the intended transmission wavelength ranges and / or transmittances ⁇ b for a filter element ⁇ pq at position p, q and can have values between 1 and b ma ⁇ ,
- n m is an integer value greater than "zero", which preferably corresponds to the integer n ',
- the (very many) directions of propagation predetermined for the light emitted by the picture elements ⁇ y intersect at a multiplicity of points, which can each correspond to an eye position of an observer.
- transmission wavelength ranges or as transmittance ⁇ b e.g. can be selected: the wavelength range of the red, green or blue light as well as for the visible light essentially opaque and transparent light transmittance.
- largely wavelength-independent transmittances can be specified, for example a transmittance of 75% for essentially all of the visible light.
- a combination of transmission wavelength ranges and degrees of transmission is also possible, e.g. 50% transparent for red light.
- Exactly one (or a few) of the 1 ..b m ax provided transmission wavelength ranges or transmittance ⁇ b is preferably selected as transparent for essentially the entire visible spectrum, while the rest Transmission wavelength ranges or transmittance ⁇ b are chosen as opaque for essentially the entire visible spectrum.
- a further advantageous embodiment of the invention is characterized in that — apart from edge regions of the filter array — each filter element ⁇ pq that is essentially transparent to visible light in at least one line [(q-1) and / or (q + 1)] and / or in at least one column [(p-1) and / or (p + 1)] immediately adjoins at least one further filter element ⁇ pq which is essentially transparent to the visible light.
- Both the picture elements ⁇ y and the filter elements ⁇ pq have an essentially polygonal, preferably rectangular, outline. Regardless of this, however, it is also possible that at least partially non-angular, approximately rounded outline sections are provided for filter elements ⁇ pq .
- At least some filter elements ⁇ pq which are adjacent to one another each adjoin one another on one or more edges of the polygonal, preferably rectangular, contour.
- each image partial information of at least two views A k is made visible, with at least one fifth of all visible image elements ⁇ y being essentially completely visible to the corresponding observer's eye.
- essentially precise partial image information of a view Ak can be perceived from some first viewing positions, while a mixed image of partial image information of several views Ak is visible from other (second) viewing positions for said viewer eye.
- This mixed image can result, on the one hand, from the shift from the first to the second viewing positions of the corresponding eye in the plane parallel to the plane of the image reproduction elements and, on the other hand, from a change in position with respect to the distance of the corresponding eye from the plane of the image reproduction elements.
- Exactly one array of filter elements ⁇ pq is preferably provided, and the distance z between said array and the grid of image elements ⁇ y, measured in the normal direction, is determined according to the following equation:
- s p denotes the average horizontal distance between two adjacent picture elements ⁇ y. If the filter array lies in the line of sight or normal in front of the grid of picture elements ⁇ y, then z is subtracted from d a ; if the filter array is behind it, z is added to d a , pd is the mean pupil distance for an observer and d a is a selectable viewing distance.
- a further advantageous embodiment provides that all filter elements ⁇ pq have the same geometric shape and all image elements ⁇ y have the same geometric shape.
- the filter elements ß pq have a horizontal and / or vertical direction by a correction factor f - for which preferably 0.95 ⁇ f ⁇ 1.05 - the geometric shape of the picture elements ⁇ y is reduced or enlarged.
- the correction factor f becomes - insofar as the filter array is located in front of the image display device in the viewing direction - as an example according to the equation
- image elements ⁇ y adjacent to one another in rows and / or in columns preferably emit light of different wavelengths or wavelength ranges, for example red, green or blue light.
- wavelengths or wavelength ranges for example red, green or blue light.
- Monochrome image generators can also be used.
- a picture display device e.g. Plasma displays, LC displays, OLEDs, OELDs, laser-based systems and other imaging devices with the most stable and defined pixel position possible.
- Image display devices with full color pixels e.g. Projection displays can also be used.
- the directions of light propagation for the light emitted by the picture elements ⁇ y are usually specified as wavelength-dependent directions of propagation.
- FIG. 1 shows the filter array of a first exemplary embodiment in arrangements according to the invention
- 3 to 5 show examples of images that are perceptible to a viewer's eye, information in the first embodiment
- FIG. 6 shows the filter array of a second exemplary embodiment in arrangements according to the invention
- FIG. 1 shows the filter array of a third exemplary embodiment in arrangements according to the invention
- FIG. 2 shows the image combination specification for creating the image to be displayed on the image display elements of the image display device in the third embodiment
- Fig. 1 3 to Fig. 5 view examples of image information perceivable for an observer eye in the third embodiment
- Fig. 6 shows the filter array of a fourth embodiment in arrangements according to the invention
- 7 shows the image combination rule for creating the image to be displayed on the image display elements of the image display device in the fourth exemplary embodiment
- Fig. 8 to Fig. 20 visual examples of image information perceivable for an observer eye in the fourth embodiment
- Fig. 23 to Fig. 25 view examples of image information perceivable for a viewer eye in the fifth embodiment
- FIG. 26 shows the filter array of a sixth exemplary embodiment in arrangements according to the invention.
- the drawings are generally not to scale. They are also cutouts.
- exactly one filter array is provided, which is located at a distance z in front of the image display device in the viewing direction.
- Transmission wavelength ranges ⁇ b are provided, the first ( ⁇ i) of which is essentially transparent to visible light and the rest ( ⁇ 2 .. ⁇ ) for the visible light are essentially opaque transmission wavelength ranges.
- the filter array in question has, for example, an extent of 31 mm (width) x 235 mm (height).
- the dashed lines shown in FIG. 1 serve only to make the individual filter elements visible in the grid (p, q); they do not exist on the physical filter array.
- the RGB subpixels are used as picture elements ⁇ y of the picture display device, so that a picture element ⁇ y has, for example, the dimensions 0.1 mm (width) x 0.3 mm height.
- Each filter element ⁇ pq is essentially the same size as a picture element ⁇ y. The exact dimensions are calculated, for example, according to the equations given earlier.
- the views Ak are, for example, perspective views of a scene or an object, which were created by means of a camera or a computer, preferably in each case from slightly offset shooting positions.
- 3 and 4 show two examples of the partial image information that is visible to an observer's eye from certain viewing positions.
- FIG. 5 A possible composition of image partial information of different views (here the views A 3 and A) which is visible to a viewer's eye is shown in FIG. 5.
- partial image information of at least two views Ak are inherently made visible from a number of monocular viewing positions in the space in front of the arrangement according to the invention for an observer eye, with at least one fifth of the visible image elements ⁇ y for the corresponding one
- the observer's eye is essentially completely visible (see Fig. 5, with all visible image elements being fully visible at the same time).
- partial view information of a view A k is essentially perceptible for a viewer eye from a few first viewing positions, while mixed images from partial view information of several views A are visible from other (second) viewing positions for a viewer eye.
- FIG. 26 shows the filter array of a sixth exemplary embodiment, which among other things also includes red, blue and green transparency wavelength ranges ⁇ b.
- a filter array can be produced, for example, as an exposed and developed photographic film, which is laminated onto a carrier substrate (e.g. glass).
- a carrier substrate e.g. glass
- Other manufacturing variants are of course conceivable.
- a component for optional switchability between a 2D mode and a 3D mode can be installed in arrangements according to the invention.
- the filter array is behind the (translucent) image display device, e.g. an LC display.
- Other variants for 2D-3D switching can be implemented in arrangements according to the invention. In special applications, the use of multiple filter arrays can also be advantageous.
- the invention offers the advantage that an improved 3D image quality is achieved, since a good channel separation of the different views for the observer eyes is achieved, in particular, from many viewing positions.
