Referring to figs. 1A to Fig. 2, according to discrete picture of the present invention, advantageously by the computer program for the treatment of image, from periodicity image I P and the reference picture IR with definite cycle, produce.
Reference picture IR show with by the color close color of seeing in iris image.Such reference picture is for example photo, pattern, text or analog.It preferably has the ratio identical with periodicity image I P.
The periodicity image I P using comprises five black picture element T1 and five white pixel T2 of one-period, in Figure 1B, illustrates.This cycle is selected as making to be suitable for by the playback system being used and being suitable for optics selector switch (consisting of rectilinear lens network) here.Such network of lenses is shown in Fig. 5 and Fig. 6.
Periodically image I P will give iris image-II-its color.Its color mode is identical with the color mode in cycle, and its resolution is identical with the resolution in cycle.Its size is measure-alike with the iris image of wishing to form.In addition, cycle and periodically image preferably have the ultimate resolution for the quality of used playback system, thereby the cycle has many pixels, this makes it possible to produce abundant gradient, and produces the pixel motion limiting better when the discrete filter of application.
Haply, the cycle defines color perceived in the rainbow effect of iris image.Enjoyably, enforcement of the present invention does not require the color that mark is to be printed, and the cycle comprises following pixel, described pixel shows as single layer (dull color or gray scale form), or shows as two layers (wherein the most shallow layer is preferably constant in the whole cycle).
According to unshowned another variant, the present invention realizes by color indicia device, and this cycle also comprises the color layer of the equivalent of used playback system permission, normally green grass or young crops, magenta, the Huang, black for printing.
With reference to figure 3 and Fig. 4, the discrete picture ID obtaining comprise below describe in detail when the discrete filter of application (displacement mapping) and pixel T1 and the T2 of the periodicity image being shifted.This displacement is here perpendicular to longitudinal network of lenses, and left.Discrete picture ID is associated with the cylindrical lens network SO that is suitable for producing iris image-II-.This reference picture application fuzzy (flou) is made it possible to show around the characteristic boundary bc of the picture in this iris image.When not having and apply in the reference picture of identical resolution when fuzzy with this periodicity image, the distinctness that this discrete picture demonstrates periodical element isolates (rupture), and fuzzy owing to not having in this reference picture, this iris image does not demonstrate characteristic boundary in essence.
In addition, iris image I I demonstrates iris visual effect, this iris visual effect shallow and deeply depend on viewing angle, and the region of viewed image is as illustrated in Fig. 4.In Fig. 4, for example, by three-dimensionally observing (for example, to intersect the visual field or use stereoscope) two images (A1 and A2) in succession, can perception rainbow effect.
Reference picture IR in Fig. 2 comprises the text consisting of to M5, without fuzzy text 1, fuzzy text 2 and gray scale pictures 3 five mark M1.
According to a preferred variant, can before the discrete filter of application, use mask (as in Figure 1A, 2 and 3), by repeating with the cycle to fill, create periodically image, the aperiodicity reserve area that does not have any rainbow effect is provided with five masks.When the discrete filter of application, the corresponding region in reference picture IR will advantageously be filled with corresponding color with null displacement.
According to another preferred variant, also can utilize mask before discrete filter so that fill this periodicity image with the region (not shown) in the cycle with different color in application.
The use of mask (not shown) can be also bonding in this discrete picture (coller) element before reproducing discrete picture,
-replace the region of discrete picture completely,
-there is opaque value,
-or even use fusion mode.
Use latter two especially to make it possible to obtain mixing of original photo and rainbow effect on photo.
The use of mask (not shown) can be also to periodicity image or discrete picture application colourity filter.

Manufacturing linear parallax fence can comprise the following steps:
In-establishment the cycle, wherein number of pixels and resolution depend on the desired resolution of this fence, for example, can use according to following equation the linear fence of the cycle generation 120LPI of 10 pixels of 1200DPI,
The resolution of resolution/this fence in number of pixels=this cycle in this cycle,
-with black picture element, fill the part in this cycle, for example 50% black picture element, as in Figure 1B
-creating periodically image, this periodicity image has the resolution identical with the described cycle, and has the size identical with desired parallax barrier, and repeats to fill according to the described cycle,
-form described periodicity image with transparent or semitransparent substrate and suitable playback system, make it possible to obtain zone of opacity for the each black picture element in described periodicity image.
Therefore, in a variant, before parallax barrier forms, also can be to showing as the discrete filter of described periodicity image applications of parallax barrier, with the displacement that distributes on the two at this parallax barrier and this discrete picture.
This association is to gather discrete picture ID and optics selector switch SO, to obtain iris image I I.When optics selector switch SO consists of lens (linear or spherical), discrete picture ID must be placed in the focal length place of described lens substantially.Haply, the thickness of the network of lenses of commercial foundation meets this requirement, to make this image must be placed in (referring to Fig. 5 and Fig. 6) on the face relative with described lens.
When optics selector switch SO is parallax barrier, is preferably in a distance is set between this fence and this ID.In order to obtain rainbow effect,, in order to make observer's eyes perception different images, preferably guarantee that this distance is not too little.
Example 1: rectilinear lens network:
In the case of the Linear Network of 120 lens of per inch and the playback system of 1200dpi, the suitable cycle will be 1200dpi, and will comprise into 10 pixels of a line, and these pixels can be for example arranged one of in the following manner:
-5 black picture elements and 5 white pixel;
-in these 10 pixels from white to black gradual change;
-from pixel 1 to pixel 5 from white to black gradual change, and from pixel 6 to pixel 10 from black to white gradual change.
Example 2: sphere lens network:
In the case of the spherical network of 120 lens of per inch and the playback system of 1200dpi, the suitable cycle will be 1200dpi, and will be the square of 10x10 pixel, and these pixels can be arranged in the following manner:
-for region (1,1) to (5,5) and region (6,6), to (10,10), be black, and
-for other regions, be white.
In order to obtain the cycle of gradual change, these pixels can be arranged in the following manner:
-from (1,1) to (1,10) and from (1,1) to (10,1) are from white to black gradual change;
-from (1,10) to (10,10) and from (10,1) to (10,10) are from black to white gradual change;
The interior pixels of-from (2,2) to (9,9) is filled with the bilinear interpolation of the pixel of the profile of restriction like this.
In order always to obtain gradual period, can create a fuzzy black circle at this square center, the pixel that retains profile is white.
This iris image is that the method by comprising the following steps creates:
(1) characterize geometry and the repetitive structure of this optics selector switch, and manufacture alternatively this optics selector switch, the mode for example describing in detail for parallax barrier above,
(2) the establishment cycle, the size (that is, the number of pixel XY) in this cycle depends on the feature of this optics selector switch and is used for the resolution of the playback system that reproduces this discrete picture,
(3) by repeat filling with the cycle, create periodically image I P.Alternatively, can utilize mask to obtain to have different color cycle several regions or do not have the aperiodicity region of any rainbow effect, or apply colourity filter,
(4) create the reference picture IR comprising elements such as picture, photo, text, pattern,
(5) by periodicity image I P being applied to discrete filter to generate discrete picture ID according to all pixels of the corresponding property image I P of pixel value moving period in this reference picture, according to following formula
ID=DispMap(IP,IR)
(6) by by associated with this optics selector switch discrete picture ID iris image-II-that produces, this optics selector switch can comprise the direct impression on the face relative with observer, to the impression after this face bonding, the reproduction of any other form.
This discrete filter (displacement mapping) requirement, for each pixel (Xip, Yip) of periodicity image I P, calculates the coordinate (Xir, Yir) of its reference pixel in this IR.
When periodicity image I P and reference picture IR have identical size and identical resolution, while having in the horizontal and vertical directions identical number of pixels, the coordinate of pixel equates respectively, according to following formula:
Wherein X
mAXir, Y
mAXirand X
mAXip, Y
mAXipbe respectively reference picture IR and the size (on x axle and y axle) of image I P periodically, and coordinate Xir, Yir, Xip, Yip are integers.
Equally, when periodicity image I P and reference picture IR have different size, the coordinate of reference pixel calculates according to following formula
In this situation, coordinate Xir, Yir are real numbers, and corresponding coordinate figure is that the bilinear interpolation of the value by adjacent both full-pixel is calculated.
About displacement calculating value, the value of the pixel of reference picture IR shows as the color such as gray scale, or shows as three values of red, green, blue.Importantly make a pixel displacement value corresponding to this color.In order to accomplish this point, preferably limit maximum displacement (Bmax), this maximum displacement is by preferably between between 1/2nd and cycle size of cycle size two times.When color changes from its minimum value to its maximal value, shift value can change from 0 to limited (Bmax) to greatest extent, or changes from-Bmax/2 to+Bmax/2.
For generation of being intended to produce, according to the means of the discrete picture of iris image of the present invention, preferably by computing machine image processing software, implemented.The discrete picture obtaining is generated then, and associated with optics selector switch, as set forth above.
In the situation of the lens type network consisting of cylindrical lens in use, or in the situation of the parallax barrier consisting of line in use, these must be vertical, to obtain best rainbow effect.But it is favourable that the angle [alpha] of these lines or lens is tilted to 65 degree from 25 degree.So rainbow effect is always protected, and also there is from top to bottom the advantage that becomes work (animer) during pivotable when substrate.
Can be undertaken by two kinds of methods:
The first comprises periodicity image I P rotation alpha degree, then fill this cycle, then with reference to image I R rotation alpha degree, then by the discrete filter of application, produce horizontal shift (dx) and create discrete picture ID, then that discrete picture ID is associated with optics selector switch SO.Then the negative α degree of this image revolution is watched to this image.
The second mode of carrying out comprises: with the cycle fill cycle image I P of α degree that tilted, then before forming, by the discrete filter of application, produce perpendicular to cylindrical lens with perpendicular to the displacement (dx of the line of parallax barrier, dy) create discrete picture, and discrete picture ID is associated with optics selector switch SO, optics selector switch SO self tilt alpha degree angle.
It should be noted that in the situation of the parallax barrier associated with discrete picture, can determine one or the other is placed on to front or rear as requested.Formation will be considered this selection.
