Detailed description of the invention
As shown in Figure 1, in synthesis microlens type 3D photo, emulsion below lenticular screen (lenticular screen) or sheet must be exposed, and makes the compressed image of different views substantially fill each lenticular substrate (base).Fig. 1 illustrates 3D photo, and wherein, the compressed image of two views is used to fill lenticular whole substrate.Usually, 3D photo can by two, three, the compressed image of view that four or more is different forms.Depend on the optical resolution of 3D photo, dozens of or hundreds of different view can the form of compressed image present.
In order to disclose the present invention, be used to explain the method and apparatus for the synthesis of 3D photo from the 3D photo of three View synthesis.According to each embodiment of the present invention, device 10 is used to make 3D photo.Device 10 comprises digital image display device 20, optical imaging apparatus 40 and keeps the retainer of printer material 60, as seen in figs. 2a-2c.As shown in figs. 3 a-3 c, printed material 60 comprises lenticular screen 70, emulsion 80 and supports the substrate (substrate) of emulsion 80, paper or coating (coating) 90.Lenticular screen 70 comprises multiple cylindrical lens (cylindrical lens) being known as lenticule 72 for being compressed image 82,84 by the compression of images projecting (project) ...Numerical display device 20 can be liquid crystal display (LCD) panel, light emitting diode (LED) panel, Plasmia indicating panel or be configured to receive DID and at different display position places, DID be shown as any display floater of image.Numerical display device 20 can show two or more images at multiple different display position place.This image can sequentially be shown during 3D photo building-up process.If image is shown in nonoverlapping position, then display device can be arranged in different positions and side by side shows these images.
Through the disclosure, display device 20 is described to be positioned in the first plane, and printed material 60 is placed in the 3rd plane and in second plane of optical imaging apparatus between the first plane and the 3rd plane (see Fig. 5).First plane and the 3rd plane substantially parallel to each other and be parallel to XY plane (see Figure 11 A and 11B).Thus, the first plane and the 3rd plane are also substantially perpendicular to Z axis (see Fig. 2 A-2C).In some embodiments of the invention, require that optical imaging apparatus laterally moves (such as, see Fig. 5,9A and 9B) in the second plane being arranged essentially parallel to the first plane.
The layout of the printing equipment 10 when Fig. 2 A illustrates the first position be presented at when the first image 32 on display device 20, to project image on printed material 60 with the first projectional angle by optical imaging apparatus 40.With this first projectional angle, the projects images on printed material 60 is compressed to suprabasil multiple compressed images 82 of the lenticule 72 of lenticular screen 70, as shown in Figure 3A.When keeping display device 20 and optical imaging apparatus 40 is static, printed material 60 is laterally moved and image 34 is presented at the second position on display device 20, makes image 34 second projectional angle to project on printed material 60, as shown in Figure 2 B.With this second projectional angle, the projects images on printed material 60 is compressed to suprabasil multiple compressed images 84 of the lenticule 72 of lenticular screen 70, as shown in Figure 3 B.When keeping display device 20 and optical imaging apparatus 40 is static, printed material 60 is laterally moved again and image 36 is presented at the 3rd position on display device 20, image 36 is made the 3rd projectional angle to project on printed material 60, as shown in Figure 2 C.With the 3rd projectional angle, the projects images on printed material 60 is compressed to suprabasil multiple compressed images 86 of the lenticule 72 of lenticular screen 70, as shown in Figure 3 C.
It should be noted that the lenticular angle θ depended on as shown in Figure 4, compressed image 82,84 and 86 can cover or can not cover the whole substrate (W) of lenticule 72.The width of compressed image is determined by Δ θ, and this Δ θ is determined by aperture (aperture) A and distance V of optical imaging apparatus 40, as shown in Figure 5.Lenticular total lenticule angle (lenticular angle) θ is determined by lenticular geometry.As shown in Figure 5, display device 20 is positioned in the first plane, and printed material 60 is positioned at and is arranged essentially parallel in the 3rd plane of the first plane.In second plane of optical imaging apparatus (or one or more amplifying lens) 40 between the first plane and the 3rd plane.In order to project on printed material 60 by image with different projectional angles, printed material is moved to the diverse location in the 3rd plane.As shown in Figure 5, U is the distance between the first plane and the second plane, and V is the distance between the 3rd plane and the second plane.Thus, the enlargement ratio of projection is V/U, and optical imaging apparatus 40 is amplifying lens effectively.Depend on total lenticule angle θ and compression angle delta θ (Fig. 4), the aperture A of optical imaging apparatus 40 can be adjusted to the quantity being suitable for the image that will be projected onto on printed material 60.In addition, depending on will by the quantity of image that projects and the aperture of amplifying lens and total lenticule angle θ, and the diverse location on display device 20 can overlap each other (Fig. 5,6B) or (Fig. 2 A-2C, 6A) separated from one another.In some cases, the diverse location of the second image is adjacent one another are, as shown in Figure 6 C.When use three images are to synthesize 3D rendering, these three images can be by one or more camera or the image creating the scene that figure (created graphics) obtains with three different angles.But three images that will expose on printed material can be incoherent image or text or graphic art (graphic arts), or their combination.
3D photo can be made up of the compressed image more than three images.The quantitative range of image used when synthesizing 3D picture or photo can from 2 to 100 or more, and this depends on lenticular resolution ratio, such as.As shown in fig 6d, four images are presented at the different position of on display device 20 four to obtain four different projectional angles.In this case, can be four different views at all four images of four different positions displays.But the image shown in the first and second positions is identical right view and is that identical left view is so that synthesis 3D photo as shown in Figure 1 is also possible at the image of the third and fourth position display.
It should be noted that some target (object) in photo may appear in the plane of photo, and some target may appear at after photographic plane, and some may appear at before photographic plane when observing 3D photo.When synthesizing 3D photo, of will appear in the target in the plane of photo is selected as main object (key subject).Such as, when synthesizing the 3D photo of scene of the people between some target context and some foreground target, this people can be selected as the main object of 3D photo.The main object be projected onto in the image on printed material must be aligned (align), make the projects images of main object by be located substantially on printed material a bit.This image registration procedure is called as main object and aims at.Such as, three images 32,34 and 36 sequentially or are side by side presented at the different position of on display device 20 three to synthesize 3D photo, as shown in Figure 7a.Main object 132,134 and 136 in these three images may not be aligned to and make the projects images of main object be positioned at identical point 160 (Fig. 7 B) on printed material 60.In that case, in order to the object that main object is aimed at, mobile display image will be needed.As shown in Figure 7 B, in order to aim at object, display image 34 upwards and towards moving left and show image 36 is moved upward.According to one embodiment of present invention, display image 34 and 36 can (electronically) realize electronically from position as shown in Figure 7 A to the movement of position as shown in Figure 7 B, but not mechanically (mechanically) realizes.Thus, during whole building-up process, can keep display device 20 and optical imaging apparatus 40 relative to each other static, and by digitally (digitally) or move one or more display image electronically and complete main object alignment procedures.
In one embodiment of the invention, display device 20 comprises single display floater, as shown in Figure 6A.So, this single display floater has enough display areas sequentially or side by side to show two or more images two different positions.In another embodiment of the present invention, display device 20 comprises two or more display floaters, as shown in Figure 8 A.As shown in Figure 8 A, display device 20 comprises three display floaters 22,24 and 26, and each in these three display floaters 22,24 and 26 is used to show an image.In a different embodiment, display device comprises two or more display floaters, but one or more panel can be used to show more than one image.As shown in Figure 8 B, when display floater 22 is used to show an image in first position, display floater 25 can be used with second and the 3rd position display image.
As shown in Figure 4, compressed image 82,84 and 86 can not fill up the whole substrate of lenticule 72, thus in 3D photo, leave some spaces (gap) or blank (blank).This will affect the quality of 3D photo.This space can be filled in several ways.A kind of mode is that the aperture of optical imaging apparatus is broadened.In one embodiment of the invention, by relative to printed material 60 laterally mobile optical imaging device 40 aperture of optical imaging apparatus 40 is broadened effectively.As shown in Figure 9 A, while by display device 20 laterally displacement 120, by optical imaging apparatus 40 displacement 140.Distance 120 equals (U+V)/V with the ratio of distance 140.The recruitment (increase) of Δ θ equals distance 140 divided by V.In a different embodiment of the present invention, replace display device 20 displacement 120, display image 32 is by displacement 132 electronically, and optical imaging apparatus 40 is by laterally displacement 140 simultaneously.As shown in Figure 9 B, image displacement 132 equals equipment moving distance 120.So, during whole building-up process, without the need to mechanically mobile display device 20.Should be appreciated that in order to fill gaps object, one or morely also mechanically or electronically can be moved together with the movement of optical imaging apparatus 40 in other display image.In a different embodiment, replace optical imaging apparatus 40 displacement 140, printed material 60 is moved distance 162, and this distance 162 equals apart from 140 but in the opposite direction, as shown in Figure 9 C.In addition, by the display image displacement 132 ' on display device 20, this distance 132 ' is substantially equal to distance 132 and deducts distance 140 (see Fig. 9 B).So, without the need to mechanically mobile optical imaging device 40.Gap filling method principle is as shown in Figure 9 C equal to method as shown in Figure 10 B.It should be noted that Fig. 9 A-9C illustrates the various methods for filling the space in lenticular substrate of when the first display image 32 exposes on printed material 60 (see Fig. 2 A).When the second display image 34 and the 3rd display image 36 expose as illustrated by figures 2 b and 2 c on printed material 60, these methods also can be used to fill space.
For filling the quantity N that the another kind of mode in the space in 3D photo is the image that increase will be exposed, so that N=is θ/Δ θ.Such as, if two images 32 and 34 are used to synthesize 3D photo (see Figure 10 A), but two compressed images do not fill up lenticular whole substrate rightly, then the quantity of display image can be increased to four the quantity of compressed image is increased to four.In embodiment as shown in Figure 10 B, image 32 is repeatedly presented at primary importance and second position, and then image 34 is repeatedly presented at the 3rd position and the 4th position.Now, the aperture of optical imaging apparatus is adjusted to make N=Δ θ=θ/4.So, display device 20 can be static relative to optical imaging apparatus 40, and only laterally mobile print material to change projectional angle (see Fig. 2 A-2C).Figure 10 C illustrates.
It should be noted that numerical display device 20 is generally made up of the two-dimensional array for showing digital picture.Pixel is organized (not shown) with the form of columns and rows.Such as, row is parallel to Y-axis, and row are parallel to X-axis, as shown in Figure 11 B.Shall also be noted that lenticular screen is made up of multiple cylindrical lens or lenticule.If the longitudinal axis of cylindrical lens is also parallel to Y-axis, then may there is moire pattern (Moire pattern) in 3D photo.In order to reduce Moire effect, can tilt printed material slightly, makes the lenticular longitudinal axis no longer be parallel to Y-axis, as shown in Figure 11 B, in another embodiment of the present invention, inclination printed material 60 is replaced, display device 20 is tilted slightly, as shown in Figure 11 A.
In a different embodiment of the present invention, as shown in figure 12, optical imaging apparatus 40 comprises multiple projection lens or amplifying lens 42.Each in amplifying lens 42 is placed regularly, and the projectional angle that multiple image 32,34,36 and 38 can be different is exposed on printed material 60.In this embodiment, all images can side by side be presented on display device 20.During whole building-up process, printed material 60 keeps static relative to display device 20 and optical imaging apparatus 40.If projection lens 42 can not be arranged, make the compressed image of image 32,34,36 and 38 can not fill up whole lenticule substrate (see Fig. 4), then can by the image 32,34,36 and 38 on mobile display device 20 electronically and in the opposite direction mechanically mobile print material 60 fill space (see Fig. 9 C).
