[0001]
BACKGROUND OF THE INVENTION
  The present invention relates to a stereoscopic image print for reproducing a stereoscopic image, and a stereoscopic image print manufacturing method, a stereoscopic image printer, and a stereoscopic image recording film for manufacturing the stereoscopic image print.
[0002]
[Prior art and problems to be solved by the invention]
  Holography is a technique for recording and reproducing information on the amplitude and phase of light waves for reproducing a stereoscopic image on a medium. When the object is irradiated with coherent light such as laser light and the recording medium is irradiated with the reflected light (object light) from the object, the recording medium is simultaneously irradiated with another coherent light (reference light). Interference fringes are formed on the recording medium. A hologram is a light intensity distribution resulting from this interference recorded in a medium as a change in refractive index or absorptance. When the recording medium on which the hologram is recorded is irradiated with only the reference light, the hologram functions as a diffraction grating and the object light is reproduced. When an object having a three-dimensional structure is used as a subject, the reproduced image is a stereoscopic image with a natural stereoscopic effect. For this reason, holography is widely used as a technique for displaying a stereoscopic still image.
[0003]
  However, holography has a problem that the photographing process is complicated, and a general person cannot easily obtain a desired three-dimensional image. For this reason, there has been a need for a mechanism for providing a personally photographed video or a personally created image as a stereoscopic image. In addition, holography has a problem that it is difficult to obtain a full-color image having high image quality and no sense of incongruity.
[0004]
  Images reproduced by normal holography are monochromatic, but there are various color holograms that can record and reproduce color images, for example, as introduced by Junpei Takiuchi's “Holography” by Yukabo (1997). It is being considered.
[0005]
  Leith et al. First proposed a color hologram. In the method of Leith et al., A color image is obtained using three holograms photographed for each color of RGB. First, an object is illuminated with three colors of RGB laser light, and three holograms are photographed for each color of laser light. Next, when each of the three holograms is illuminated by using the same color laser light as that used for photographing, the reproduced images of the three RGB colors appear at the same position to reproduce the color image.
[0006]
  However, there is a drawback that a so-called ghost image appears because each color laser beam is diffracted by each of the three holograms during reproduction. In addition, a reconstructed image without a ghost image can be obtained by placing a Foucault grating on the reference optical system at the time of photographing so that the three holograms do not overlap, but for reproduction, the reference optical system at the time of photographing The same optical system is necessary and complicated.
[0007]
  In addition, a color image can be recorded and reproduced by a rainbow hologram or a Lippmann hologram. The rainbow hologram is taken so that the spatial carrier wave of the hologram is in the horizontal direction. By shooting three rainbow holograms at the respective RGB wavelengths and illuminating them with white light, the reproduced images from the three holograms appear at the same position, and a color image is reproduced. . However, in the rainbow hologram, the position where an image with a correct color balance can be seen is determined, and there is a drawback that the color reproduction becomes worse if the eyes are moved from there.
[0008]
  The Lippmann hologram is a color hologram in which interference fringes are written in each of the photosensitive layers provided corresponding to the three RGB colors of a photosensitive material having a thickness such as a silver halide photosensitive material. Reproduced images from the respective photosensitive layers appear at the same position, and a color image is reproduced. However, since the photosensitive layer shrinks during development, there is a drawback that an image different from that during photographing is reproduced during reproduction.
[0009]
  A color hologram can also be created using a stereogram, but a stereogram uses multiple two-dimensional photographic images to write intensity images that can be seen from various angles, up to the light phase control. Not.
[0010]
  Unlike holograms taken normally, a computer-generated hologram is called a computer generated hologram (CGH). This is a hologram created by calculating the structure (amplitude and phase distribution of object light) of the hologram itself using a computer. A hologram synthesized from a large number of ordinary photographs is called a holographic stereogram.
[0011]
Recently, a small device called a hologram printer that synthesizes holographic stereograms from image data stored in a computer has also been developed (M. Yamaguchi, N. Ohyama, T. Honda, "Holographic three-dimensional printer" : new method, "Applied Optics 31, pp.217-222 (1992), Nobuhiro Kihara, Akira Shirakura, Shigeyuki Baba," High-Speed Hologram Portrait Print System, "3D Image Conference '98, pp.257-262 (1998) ). However, this hologram printer has a drawback that a complicated optical system is necessary for exposure using light interference, and high accuracy is required at the time of writing.
[0012]
  It is also possible to display a stereoscopic image from image data stored in a computer using a two-dimensional spatial light modulator. For example, a liquid crystal spatial modulator is used to control the amplitude and phase of transmitted light by changing the absorptance and refractive index for each fine cell to reproduce a stereoscopic image. Compared with the case where a reproduced image is obtained by diffraction due to interference fringes, this method prevents the appearance of a phase conjugate image and prevents ghost images due to other wavelengths by spatially separating the three primary colors of light RGB. it can. In addition, there is an advantage that high diffraction efficiency can be obtained (a bright image can be reproduced). However, with the current technology, the liquid crystal pixels of the spatial modulator are as large as about 100 μm and it is difficult to increase the area, so that it is difficult to display a stereoscopic image that can withstand viewing. Another disadvantage is that the cost is high for the purpose of enjoying still images.
[0013]
  Further, it is known that the density of a photographic film changes depending on the exposure amount, and relief formation and refractive index change occur due to expansion / contraction. A technique for recording the amplitude distribution and phase distribution of object light calculated by a computer on a photographic film using this is called a kinoform. For example, using a reversal color film, the amplitude distribution is recorded in the red photosensitive layer, and the phase distribution is recorded in the blue photosensitive layer and the green photosensitive layer. The reversal color film after recording can be reproduced with a red laser (HeNe laser) to reproduce character images with parallax (DCChu, JRFienup, JWGoodman, "Multiemulsion on-axis computer generated hologram," Applied Optics 12, pp.1386-1388 (1973)). However, even if a reversal color film is used, the obtained image is a single color image.
[0014]
  As described above, with the conventional holographic technique, a desired three-dimensional image (stereoscopic image print) cannot be easily obtained, and a high-quality, full-color three-dimensional image that does not feel uncomfortable cannot be obtained.
[0015]
  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a three-dimensional image print, a method for producing a three-dimensional image print, a three-dimensional image print capable of easily obtaining a high-quality and full-color three-dimensional image. It is to provide a printer and a stereoscopic image recording film.
[0016]
[Means for Solving the Problems]
(First stereoscopic image print, etc.)
  In order to achieve the above object, the first stereoscopic image print according to the present invention includes a phase information for reproducing a stereoscopic image and a phase for each small area of image data in which amplitude information for each color is divided into small areas. Based on the information, the phase modulation layer in which the optical path length of each small region is changed and the corresponding small region corresponding to each of the small regions of the phase modulation layer are amplitude information for each small region of the image data. And a filter layer in which a plurality of color filters for each color are stacked, and the filter layer is formed by stacking a plurality of color filters for each color.
[0017]
  In the first stereoscopic image print, the phase modulation layer is configured to output phase information for reproducing a stereoscopic image and amplitude information for each color based on phase information for each small region of image data represented by dividing each small region. Since the optical path length of the small region is changed, the phase of the transmitted light can be modulated. In order to change the optical path length, the refractive index, thickness, or refractive index and thickness of the phase modulation layer may be changed.
[0018]
  The filter layer is formed for each color in which each of the corresponding small areas corresponding to each of the small areas of the phase modulation layer changes in transmittance based on amplitude information for each small area of the image data. Since a plurality of color filters are stacked, the amplitude of transmitted light can be modulated for each color. For this reason, when light is incident on the stereoscopic image print, the phase, amplitude, and wavelength of the transmitted light are controlled for each small area, and the recorded stereoscopic image (hologram) is reproduced.
[0019]
  As described above, since each piece of information is recorded in the form of dots instead of interference fringes, the recording optical system and the reproduction optical system are simplified and the occurrence of ghost is prevented. In addition, the filter layer that modulates the amplitude of the transmitted light is formed by stacking color filters for each color, so there is no need to provide a separate color separation filter, and the manufacturing process is simplified and color misregistration occurs. It becomes difficult to do. As a result, it is possible to easily obtain a color stereoscopic image having high image quality and no sense of incongruity. In particular, when each of the colors is red, green, and blue, it is possible to easily obtain a full-color three-dimensional image with high image quality and no sense of incongruity.
[0020]
  In the manufacture of the first stereoscopic image print described above, the stereoscopic information for recording the phase information and the amplitude information of the image data represented by dividing the phase information for reproducing the stereoscopic image and the amplitude information for each color into the small areas. A recording film, a phase recording photosensitive layer provided for recording phase information, and a plurality of amplitude recording photosensitive layers provided corresponding to each color for recording amplitude information for each color Can be used.
[0021]
  For example, a first photosensitive layer in which phase information is recorded by changing an optical path length of each small region by exposure based on phase information for each small region of the image data and development after the exposure, and the image data A second photosensitive layer in which a red filter is formed by changing the transmittance by exposure based on amplitude information for each small area corresponding to red and development after the exposure, and red amplitude information is recorded; A third photosensitivity in which a green filter is formed by changing the transmittance by exposure based on amplitude information for each small area corresponding to green of the image data and development after the exposure, and green amplitude information is recorded. A blue filter is formed by changing the transmittance by the exposure based on the amplitude information of each layer corresponding to the blue color of the image data and the development after the exposure, and the blue amplitude information is recorded. A three-dimensional image in which four photosensitive layers are laminated It can be used as the recording film.
[0022]
  In this stereoscopic image recording film, it is more preferable that at least one photosensitive layer is composed of a silver halide photosensitive material. The silver halide photosensitive material is inexpensive and has high sensitivity, and image data can be written using a low-power laser light source. As a result, a stereoscopic image can be created at low cost and can be used for personal use.
[0023]
  Then, each of the plurality of photosensitive layers for recording amplitude is exposed with light modulated for each color according to the amplitude information for each small area of the image data, and then developed to expose the transmittance of each small area. Amplitude information is recorded according to the amount, thereby forming a filter layer in which a plurality of color filters for each color are stacked, and corresponding to each of the small areas of the filter layer of the phase recording photosensitive layer. Each of the corresponding small areas is exposed with light modulated in accordance with the phase information for each small area of the image data and then developed, and the optical path length of each small area is changed in accordance with the exposure amount to thereby change the phase modulation layer The three-dimensional image print can be manufactured.
[0024]
  The first stereoscopic image print includes, for example, a phase recording light source that outputs light modulated in accordance with phase information for each small area of the image data, and amplitude information for each small area of the image data. A light source for amplitude recording for each color that outputs light modulated for each color in response to the light, and exposing the photosensitive layer for phase recording with light output from the light source for phase recording, and a plurality of amplitude recording light sources Exposure means for exposing each of the photosensitive layers with light of each color output from an amplitude recording light source for each color, and developing means for developing the three-dimensional image recording film exposed by the exposure means. It can be manufactured using a stereoscopic image printer.
[0025]
  In the manufacturing method and the stereoscopic image printer for manufacturing the first stereoscopic image print described above, the image data is written using the output light from the light source, and therefore the computer is used by using the same method and apparatus as those for digital exposure on the photographic paper. A hologram can be recorded. Further, exposure can be performed with high resolution by narrowing the beam waist of the laser beam. In order to prevent crosstalk, it is preferable to expose the photosensitive layer for phase recording with light having a wavelength band different from that for exposing the photosensitive layer for amplitude recording.
[0026]
(Second stereoscopic image print, etc.)
  In order to achieve the above object, the second stereoscopic image print according to the present invention is configured such that the phase information and the amplitude information for each color for reproducing a stereoscopic image are divided for each small area of the image data. The phase modulation layer in which the optical path length of each small region is changed based on the phase information of the phase modulation layer, and the corresponding small region corresponding to each of the small regions of the phase modulation layer have an amplitude for each small region of the image data. An amplitude modulation layer formed so that the transmittance changes based on information, and a color separation filter layer in which a large number of small region filters for each color are arranged corresponding to the small region are stacked. It is characterized by that.
[0027]
  In the second stereoscopic image print, the phase modulation layer is based on the phase information for each small area of the image data in which the phase information and the amplitude information for each color for reproducing the stereoscopic image are divided into small areas. Since the optical path length of each small region corresponding to the small region filter is changed, the phase of the transmitted light can be modulated. Since the amplitude modulation layer is formed such that each of the corresponding small areas corresponding to each of the small areas of the phase modulation layer changes the transmittance based on the amplitude information for each small area of the image data, The amplitude of the transmitted light can be modulated. A large number of small area filters for each color are arranged in the color separation filter layer, and the wavelength of transmitted light is selected by each small area filter. For this reason, when light is incident on the stereoscopic image print, the phase, amplitude, and wavelength of the transmitted light are controlled for each small area, and the recorded stereoscopic image (hologram) is reproduced.
[0028]
  As described above, since each piece of information is recorded in the form of dots instead of interference fringes, the recording optical system and the reproduction optical system are simplified and the occurrence of ghost is prevented. Further, since the color separation filter layer is provided separately from the amplitude modulation layer, it can be a single amplitude modulation layer regardless of the number of colors, and the manufacturing process is simplified. As a result, it is possible to easily obtain a color stereoscopic image having high image quality and no sense of incongruity. In particular, when each of the colors is red, green, and blue, it is possible to easily obtain a full-color three-dimensional image with high image quality and no sense of incongruity.
[0029]
  In the production of the above-described second stereoscopic image print, the stereoscopic information for recording the phase information and the amplitude information of the image data in which the phase information and the amplitude information for each color for reproducing the stereoscopic image are divided for each small area is recorded. A recording film comprising a phase recording photosensitive layer provided for recording phase information and an amplitude recording photosensitive layer provided for recording amplitude information is used. Canit can.
[0030]
  thisIn the stereoscopic image recording film, it is more preferable that at least one photosensitive layer is composed of a silver halide photosensitive material. The silver halide photosensitive material is inexpensive and has high sensitivity, and image data can be written using a low-power laser light source. As a result, a stereoscopic image can be created at low cost and can be used for personal use.
[0031]
  And for the amplitude recordingSmall area of photosensitive layerEach of the corresponding small regions corresponding to each of the image data is developed after being exposed with light modulated for each color according to the amplitude information for each small region of the image data, and the transmittance of each small region is determined according to the exposure amount. The amplitude information is recorded by changing the amplitude information to form an amplitude modulation layer, and each of the corresponding small areas corresponding to each of the small areas of the color separation filter layer of the photosensitive layer for phase recording is Three-dimensional image prints are produced by developing after exposure with light modulated according to the phase information for each small area of data, forming the phase modulation layer by changing the optical path length of each small area according to the exposure amount can do.
[0032]
  The second stereoscopic image print includes a three-dimensional image including a phase recording photosensitive layer provided for recording phase information and an amplitude recording photosensitive layer provided for recording amplitude information. After forming an amplitude modulation layer and a phase modulation layer using an image recording film, a color separation filter in which a plurality of small area filters for each color are arranged corresponding to the small area is bonded to the stereoscopic image recording film. Thus, the second stereoscopic image print can be manufactured.
[0033]
  The second stereoscopic image print includes, for example, a phase recording light source that outputs light modulated according to phase information for each small area of the image data, and amplitude information for each small area of the image data. And an amplitude recording light source that outputs light modulated for each color, and the phase recording photosensitive layer is exposed to the light output from the phase recording light source, and the amplitude recording photosensitive layer has an amplitude. An exposure means for exposing with light output from a recording light source, a developing means for developing the stereoscopic image recording film exposed by the exposure means, and a plurality of small area filters for each color corresponding to the small areas The color separation filter can be manufactured using a stereoscopic image printer including a bonding unit that bonds the color separation filter to the stereoscopic image recording film.
[0034]
  In the manufacturing method and the stereoscopic image printer for manufacturing the second stereoscopic image print described above, the image data is written using the output light from the light source, and therefore the computer is used by using the same method and apparatus as the digital exposure on the photographic paper. A hologram can be recorded. Further, exposure can be performed with high resolution by narrowing the beam waist of the laser beam. In order to prevent crosstalk, it is preferable to expose the photosensitive layer for phase recording with light having a wavelength band different from that for exposing the photosensitive layer for amplitude recording.
[0035]
(Third stereoscopic image print etc.)
  Further, in order to achieve the above object, the third stereoscopic image print of the present invention is arranged such that the phase information and the amplitude information for each color for reproducing a stereoscopic image are divided for each small area of the image data. Based on the phase information of each phase, the phase modulation layer in which the optical path length of each small region is changed, and a material containing ink of different colors for each color, and each of the small regions of the phase modulation layer Each of the corresponding corresponding small regions is composed of color filters for each color formed so that the transmittance changes based on the amplitude information for each small region of the image data, and a large number of color filters for each color are planar. And an ink layer arranged in a shape.
[0036]
  In the third stereoscopic image print, each of the phase modulation layers is based on the phase information for reproducing each stereoscopic image and the amplitude information for each color based on the phase information for each small area of the image data represented by dividing each small area. Since the optical path length of the small region is changed, the phase of the transmitted light can be modulated. In addition, each of the corresponding small areas of the ink layer is formed with a color filter for each color so that the transmittance changes based on the amplitude information for each small area of the image data. Is modulated. For this reason, when light is incident on the stereoscopic image print, the phase, amplitude, and wavelength of the transmitted light are controlled for each small area, and the recorded stereoscopic image (hologram) is reproduced.
[0037]
  As described above, since each piece of information is recorded in the form of dots instead of interference fringes, the recording optical system and the reproduction optical system are simplified and the occurrence of ghost is prevented. In addition, the ink layer that modulates the amplitude of transmitted light is easy to form, and the color filter for each color is arranged in a plane, so there is no need to provide a separate color separation filter and the manufacturing process is simplified. Color misregistration is less likely to occur. Further, only the photosensitive layer for phase recording needs to be exposed, and the exposure optical system is simplified. As a result, it is possible to easily obtain a color stereoscopic image having high image quality and no sense of incongruity. In particular, when each of the colors is red, green, and blue, it is possible to easily obtain a full-color three-dimensional image with high image quality and no sense of incongruity.
[0038]
  The third three-dimensional image print uses a three-dimensional image recording film provided with a phase recording photosensitive layer provided for recording phase information, and the phase recording photosensitive layer is transferred to the image data. Development is performed after exposure with light modulated according to phase information for each small region, and a phase modulation layer is formed by changing the optical path length of each small region according to the exposure amount. Each of the corresponding small areas is applied to each of the corresponding small areas corresponding to each by applying a material containing ink of a color having a different absorption wavelength for each color according to the amplitude information for each small area of the image data. The ink layer can be manufactured by forming an ink layer in which a number of color filters for each color are arranged in a plane.

[0040]
DETAILED DESCRIPTION OF THE INVENTION
  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
(First embodiment)
  FIG. 1 shows a system configuration of a stereoscopic image printer according to the present embodiment. This stereoscopic image printer is provided with a storage unit 12 for storing a silver salt film 10 wound in a roll shape. A plurality of transport rollers 14 for transporting the silver salt film 10 supplied from the storage unit 12 are arranged along the transport path. The plurality of transport rollers 14 are driven by a transport driving unit (not shown).
[0041]
  On the downstream side of the storage unit 12 in the conveying direction, an exposure unit 15 that scans and exposes the silver salt film 10 with laser light in accordance with image data, develops the exposed silver salt film 10 and fixes and develops the developed film. A development processing unit 16 for processing, a dryer 18 for drying the film processed by the development processing unit 16, and a cutter 20 for cutting the film for each image forming area are arranged in this order.
[0042]
  The exposure unit 15 includes four color laser light sources, a red laser light source 22R, a green laser light source 22G, a blue laser light source 22B, and an ultraviolet laser light source 22UV, a polygon mirror 24 that reflects the laser light emitted from these laser light sources, and a polygon. An fθ lens 26 for correcting the laser beam reflected by the mirror 24 so as to converge on the surface of the silver salt film 10 is provided.
[0043]
  As the laser light sources 22R, 22G, 22B, and 22UV, solid lasers, fiber lasers, wavelength conversion solid lasers, gas lasers, surface emitting lasers, and the like can be used in addition to semiconductor lasers. From this point of view, it is preferable to use a semiconductor laser or a solid-state laser.
[0044]
  For example, a semiconductor laser that emits light in the wavelength range of 600 to 700 nm is used for the red laser light source 22R, and a semiconductor laser-excited wavelength conversion solid-state laser that emits light in the wavelength range of 500 to 600 nm is used for the green laser light source 22G. A semiconductor laser-excited wavelength conversion solid-state laser that emits light in the wavelength range of 450 to 500 nm can be used as the light source 22B, and a semiconductor laser that emits light in the wavelength range of 350 to 450 nm can be used as the ultraviolet laser light source 22UV.
[0045]
  Each of the four color laser light sources is modulated by a modulation driving device (not shown) controlled by the computer 28. As the modulation driving device, for example, an external modulator such as an electro-optic modulator (EOM) can be arranged, and the external modulator can be driven to modulate the intensity of the laser light from the laser light source. When a semiconductor laser is used, the semiconductor laser may be directly modulated and driven without using an external modulator. The computer 28 includes a memory, a CPU, a ROM, a RAM, and the like.
[0046]
  In the development processing unit 16, a developing tank 30 for storing a developing solution, a fixing tank 32 for storing a fixing solution, and a bleaching tank 34 for storing a bleaching solution are arranged in this order toward the downstream side in the transport direction.
[0047]
  Next, the layer configuration of the silver salt film 10 used in the above-described stereoscopic image printer will be described. As shown in FIG. 2, the silver salt film 10 is provided with a plurality of photosensitive layers each containing a silver halide emulsion and a color coupler, each having a different sensitivity, like a so-called reversal color film. On the film-like support 36, a blue photosensitive layer 38 sensitive to blue light, a green photosensitive layer 40 sensitive to green light, a red photosensitive layer 42 sensitive to red light, and sensitive to ultraviolet light. Four photosensitive layers of the ultraviolet photosensitive layer 44 are laminated in this order from the support side. These photosensitive layers are formed by coating a photosensitive material containing a silver halide emulsion and a color coupler on a support. An intermediate layer 46 composed of a color filter or the like is inserted between each photosensitive layer in order to increase the single photosensitivity of each photosensitive layer. The intermediate layer 46 may be omitted.
[0048]
  Of the four photosensitive layers, the blue photosensitive layer 38, the green photosensitive layer 40, and the red photosensitive layer 42 (RGB layer) are exposed to laser light having a predetermined wavelength whose intensity is modulated in accordance with amplitude information, and light after development. The transmittance is changed, and color filters in which the light transmittance is changed for each small area described later are formed in each layer of the RGB layer. In the exposed area, silver salt is bonded, and the coupler in that area reacts during development to develop color. At this time, the internal refractive index changes due to a change in chemical properties in the silver salt layer. Further, since silver is removed by the bleaching treatment, the internal thickness also changes at the same time. Both of these effects change the optical path length of the exposed area.
[0049]
  The ultraviolet photosensitive layer 44 is exposed with ultraviolet laser light whose intensity is modulated in accordance with phase information so that a change in optical path length due to exposure and development of the RGB layer and the ultraviolet photosensitive layer 44 becomes a desired value. That is, the ultraviolet photosensitive layer 44 is exposed with an ultraviolet laser beam whose intensity is modulated in accordance with phase information so as to obtain a desired optical path length change in consideration of the optical path length change due to exposure and development of the RGB layer. A phase modulation layer that modulates the phase of transmitted light is formed by the change in length.
[0050]
  Next, a method for producing a stereoscopic image print (stereophotograph) from the silver salt film shown in FIG. 2 using the stereoscopic image printer shown in FIG. 1 will be described. The manufacturing process of a stereoscopic image print is roughly divided into an exposure process and a development process.
[0051]
  The stereoscopic image printer is controlled by the computer 28, and the silver salt film 10 is exposed according to the processing routine shown in FIG. First, in step 100, image data for stereoscopic photography prepared in advance from the memory of the computer 28 is read.
[0052]
  The image data for stereoscopic photography is image data represented by dividing phase information for reproducing a stereoscopic image and amplitude information for each color of RGB into small areas described later. Such image data includes, for example, image information including 3D data designed by 3D CAD or the like, or 3D data reconstructed from a 2D image into a 3D image by a computer. It is obtained by calculation in consideration of the position, the position of the reproduction illumination light source, the position of the viewpoint, the shape of the film, and the like.
[0053]
  Next, in step 102, considering that the optical path length changes according to the exposure amount of the RGB layer due to shrinkage accompanying exposure, etc., the target optical path length change by the RGB layer and the optical path length change by the ultraviolet photosensitive layer 44 The exposure amount of the ultraviolet photosensitive layer 44 by the ultraviolet laser light source 22UV is calculated so that the phase modulation amount can be obtained.
[0054]
  Next, in step 104, the conveyance of the silver salt film 10 is started. That is, the silver salt film 10 is pulled out of the storage unit 12 so that the ultraviolet photosensitive layer 44 side faces the exposure unit 15, conveyed at a predetermined speed, and supplied to the exposure unit 15.
[0055]
  Next, in step 106, the four color laser light sources are modulated and driven, and the silver salt film 10 is exposed. As shown in FIGS. 4A and 4B, the predetermined exposure region 48 of the silver salt film 10 is exposed with ultraviolet laser light for each of the small regions 50 arranged in a lattice pattern, and any one of RGB colors. It is exposed with laser light. For example, an R color area exposed with red light, a G color area exposed with green light, and a B color area exposed with blue light are repeatedly arranged in the order of RGB, and the adjacent RGB three color areas are defined as one pixel. Full color exposure is possible. 4A is a plan view of the silver salt film after the development processing, and FIG. 4B is a cross-sectional view of the silver salt film at the time of exposure.
[0056]
  The laser light emitted from the red laser light source 22R is intensity-modulated by a light modulator (not shown) driven by a modulation driving device (not shown) based on the amplitude information of the R color. Focused on top. The laser light reflected by the polygon mirror 24 is corrected by the fθ lens 26, converged in a dot shape on the surface of the silver salt film 10 so as to be focused by the red photosensitive layer 42, and a small region corresponding to the R color is exposed. The
[0057]
  Similarly, the laser light emitted from the green laser light source 22G is intensity-modulated based on the amplitude information of the G color, converges in a dot shape so as to be focused by the green photosensitive layer 40, and has a small region corresponding to the G color. Exposed. The laser light emitted from the blue laser light source 22B is intensity-modulated based on the amplitude information of the B color, converges in a dot shape so as to be focused by the blue photosensitive layer 38, and a small region corresponding to the B color is exposed. Is done.
[0058]
  The laser light emitted from the ultraviolet laser light source 22UV is intensity-modulated based on the phase information and converges in a dot shape so as to be focused on the ultraviolet photosensitive layer 44. As a result, a small area corresponding to the small area exposed by laser light of any one of RGB is exposed.
[0059]
  The beam diameter of the laser beam on the surface of the silver salt film 10 is preferably less than 20 μm in order to obtain high resolution.
[0060]
  Since the polygon mirror 24 is rotationally driven at a predetermined angular velocity in the direction of arrow A by a polygon drive unit (not shown), the surface of the silver salt film 10 is moved in the direction of arrow B (film width direction) by the laser light reflected by the polygon mirror 24. Main scan is performed. The silver salt film 10 is transported in a predetermined direction by a plurality of transport rollers 14 and is sub-scanned in the direction opposite to the transport direction. In this way, the silver salt film 10 is scanned and exposed by the laser beam, and a latent image corresponding to the image data is recorded. The polygon driving unit, the conveyance driving unit, and the modulation driving device are controlled by the computer 28 in synchronization with exposure.
[0061]
  Next, in step 108, it is determined whether or not the exposure according to the input image data has been completed. If the exposure has been completed, the processing routine is terminated and the film transport is stopped. If the exposure has not been completed, the process returns to step 102 to expose the next area.
[0062]
  The development processing step is a step of visualizing (developing) the latent image recorded on the exposed silver salt film 10 and fixing and bleaching the latent image. The silver salt film 10 supplied to the development processing unit 16 is conveyed by the conveyance roller 14, immersed in the developer stored in the developing tank 30, developed, and then the fixing solution stored in the fixing tank 32. Then, it is immersed in a bleaching solution and then bleached and stored in a bleaching solution stored in a bleaching tank 34. In the ultraviolet photosensitive layer 44 existing on the film surface, the developed silver is dissolved and removed in the bleaching solution by the bleaching process, and the thickness of the ultraviolet photosensitive layer 44 becomes thinner as the exposure intensity is higher. The silver salt film 10 processed by the development processing unit 16 is dried by a dryer 18 and cut by a cutter 20 for each image forming area.
[0063]
  As a result of the development processing of the silver salt film 10, each of the exposed portions of the RGB layer exposed at the exposure amount corresponding to the image data, that is, each of the small regions develops color at a density corresponding to the exposure intensity. A density (light transmittance) distribution is formed. When one small region is viewed in the stacking direction, only one of the RGB layers is colored, so each layer of the RGB layer becomes a color filter that selectively transmits light of a color (wavelength band) corresponding to each layer. . Thereby, the RGB layer is a filter layer in which RGB color filters for modulating the amplitude of transmitted light according to the wavelength band are stacked. Further, the development process changes the refractive index and thickness (optical path length) of the ultraviolet photosensitive layer 44 in accordance with the exposure intensity of the ultraviolet light, and the phase modulation layer modulates the phase of the transmitted light in accordance with the change in the optical path length. It becomes.
[0064]
  Accordingly, when the developed silver salt film 10 (stereoscopic image print) is irradiated with white light from the support 36 side, the filter layers (RGB layers after development: blue photosensitive layer 38, green photosensitive layer 40, and red photosensitive layer). 42), the RGB light is absorbed at different ratios for each small area, the transmission wavelength is selected, the amplitude is modulated, the phase is modulated by the phase modulation layer (development ultraviolet photosensitive layer 44), and the transmitted light is transmitted. Is ejected. As a result, a full-color stereoscopic image is reproduced. That is,FIG.As shown in FIG. 5, the light is diffracted by the stereoscopic image print, the phase and amplitude of the transmitted light are modulated, and the wavefront of the object light of the three-dimensional object is reproduced. Therefore, a three-dimensional object image having a different shape depending on the observation position is observed.
[0065]
  As described above, in this embodiment, an inexpensive and highly sensitive silver salt film is used for the photosensitive material, so that image data can be written with a low-power laser light source and a stereoscopic image can be created at a low cost. Can be used for personal use.
[0066]
  In the present embodiment, since image data is written on a silver salt film using a laser light source, a computer generated hologram can be recorded using the same method and apparatus as digital exposure on photographic paper. Further, exposure can be performed with high resolution by narrowing the beam waist of the laser beam.
[0067]
  In the present embodiment, the ultraviolet photosensitive layer is irradiated with ultraviolet laser light whose intensity is modulated in accordance with the phase information to change the optical path length of the ultraviolet photosensitive layer. Therefore, the ultraviolet photosensitive layer transmits the transmitted light according to the change. It acts as a phase modulation layer that modulates the phase. Further, since the phase information is written in the form of dots by using ultraviolet laser light instead of writing interference fringes, the optical system is simplified and the wavefront can be stably reproduced.
[0068]
  Furthermore, in this embodiment, since color filters for each of the RGB colors are formed in the RGB layer by laser exposure, there is no need to attach color separation filters as in the second embodiment described below, and a stereoscopic image The print manufacturing process is simplified. Also, instead of writing interference fringes, amplitude information for each color is written in dots in each layer of the RGB layer, so that a color hologram without a ghost image is formed.
[0069]
  In the present embodiment, a silver salt film in which four photosensitive layers of a blue photosensitive layer, a green photosensitive layer, a red photosensitive layer, and an ultraviolet photosensitive layer are laminated in this order from the support side is used. The arrangement order is not limited to this order. However, when a UV cut filter is inserted as an intermediate layer between the RGB layer and the ultraviolet photosensitive layer, the ultraviolet photosensitive layer needs to be the outermost layer. In addition, to prevent crosstalk, the photosensitive layer is cut from the ultraviolet photosensitive layer, the cut filter that cuts light from the ultraviolet to the short wavelength, the blue photosensitive layer, the blue cut filter that cuts blue light, the green photosensitive layer, and the green light. The green cut filter and the red photosensitive layer are preferably laminated in this order. Further, a black absorbing layer may be inserted between the photosensitive layer and the support to prevent exposure due to unnecessary stray light.
[0070]
(Second Embodiment)
  In the first embodiment, the filter layer is formed by laser exposure of the RGB layer, but in the second embodiment,A silver salt film on which no color separation filter layer is formed is used, and a film-like color separation filter is attached to the silver salt film after development. In this case, the silver salt film is exposed for each color area divided in advance. Then, by providing a reference marker on both the color separation filter and the silver salt film, the color separation filter and the silver salt film so that the color area formed by exposure and the color area formed on the color separation filter overlap each other. And paste together.FIG. 5 shows a system configuration of the stereoscopic image printer according to the present embodiment. Only parts that are different from the stereoscopic image printer according to the first embodiment will be described, and the same components will be denoted by the same reference numerals and description thereof will be omitted.
[0071]
  The exposure unit 15 includes two color laser light sources, a red laser light source 22R and a blue-violet laser light source 22BU. Each of the two color laser light sources is modulated by a modulation driving device (not shown) controlled by the computer 28.
[0072]
  As the laser light sources 22R and 22BU, a solid-state laser, a fiber laser, a wavelength conversion solid-state laser, a gas laser, a surface-emitting laser, and the like can be used in addition to a semiconductor laser. Preferably a laser or a solid state laser is used. For example, a semiconductor laser that emits light in the wavelength range of 600 to 700 nm can be used for the red laser light source 22R, and a semiconductor laser that emits light in the wavelength range of 400 to 500 nm can be used for the blue-violet laser light source 22BU.
[0073]
  For the production of stereoscopic image prints, there is a stereoscopic image recording film for recording phase information and amplitude information of image data in which phase information and amplitude information for each color for reproducing a stereoscopic image are divided into small areas. A three-dimensional image recording film comprising a phase recording photosensitive layer provided for recording phase information and an amplitude recording photosensitive layer provided for recording amplitude information can be used.
[0074]
  Of the two photosensitive layers,Photosensitive layer for amplitude recordingThe (red photosensitive layer 42A) is exposed to a laser beam having a predetermined wavelength whose intensity is modulated according to the amplitude information, and the light transmittance and the optical path length after development change. Also,Photosensitive layer for phase recordingThe (blue-violet photosensitive layer 44A) is exposed with ultraviolet laser light whose intensity is modulated in accordance with the phase information so that the optical path length change due to exposure and development of the red photosensitive layer 42A and the blue-violet photosensitive layer 44A becomes a desired value.
[0075]
  As shown in FIG. 6, the color separation filter layer 52 is composed of RGB color filters (R color filter, G color filter, and B color filter). Each color filter is arranged in a grid so as to correspond to the divided small areas, with RGB as a repeating unit, similarly to the exposure area described in FIG.Yes. In additionAdjacent RGB color filters can be one pixel. Also, the RGB color filters may be arranged in other arrangements.Good.
[0076]
  Next, the stereoscopic image printer shown in FIG.Used, solidA method for producing an image print will be described. The manufacturing process of this three-dimensional image print is substantially the same as that of the first embodiment, except that the two color laser light sources of the red laser light source 22R and the blue-violet laser light source 22BU are modulated and driven to expose the silver salt film 10A. Therefore, the description of the same part will be omitted and only the difference will be described.
[0077]
  The image data for stereoscopic photography is configured by dividing phase information and amplitude information for reproducing a stereoscopic image into small areas for each RGB color of one pixel.
[0078]
  FIG.As shown inPre-exposure areaSince it is divided into three color areas of RGB, the silver salt film 10A is divided into small areas corresponding to the color filters of the color separation filter layer 52.Exposed.
[0079]
  By the development process, the red photosensitive layer 42A of the silver salt film 10A develops color at a density corresponding to the exposure intensity, and the light transmittance changes for each small area. The amplitude of the transmitted light is changed according to the change in the light transmittance. It becomes an amplitude modulation layer for modulation. In addition, due to the development process, the blue-violet photosensitive layer 44A has its refractive index and thickness (optical path length) changed for each small area according to the exposure intensity with blue-violet light, and the transmitted light is changed according to this optical path length change. The phase modulation layer modulates the phase.
[0080]
  Therefore, when the developed silver salt film 10A is irradiated with white light from the support 36A side, the amplitude is modulated for each small region by the amplitude modulation layer (the developed red photosensitive layer 42A), and then the phase modulation layer ( The phase is modulated for each small region by the developed blue-violet photosensitive layer 44A), and then the transmission wavelength is selected according to the color filter color of the color separation filter layer 52, and the transmitted light is emitted. As a result, a full-color stereoscopic image is reproduced.
[0081]
  As described above, in this embodiment, an inexpensive and highly sensitive silver salt film is used for the photosensitive material, so that image data can be written with a low-power laser light source and a stereoscopic image can be created at a low cost. Can be used for personal use.
[0082]
  In the present embodiment, since image data is written on a silver salt film using a laser light source, a computer generated hologram can be recorded using a method and apparatus similar to those used for digital exposure on photographic paper. Further, exposure can be performed with high resolution by narrowing the beam waist of the laser beam.
[0083]
  In this embodiment, the blue-violet photosensitive layer is irradiated with blue-violet laser light whose intensity is modulated in accordance with the phase information to change the optical path length of the blue-violet photosensitive layer. It acts as a phase modulation layer that modulates the phase. Further, since the phase information is written in the form of dots by blue-violet laser light instead of writing interference fringes, the optical system is simplified and the wavefront can be stably reproduced.
[0084]
  This embodimentThen singleThe amplitude information for the three colors of RGB can be written with the laser light source, and the configuration of the exposure unit of the stereoscopic image printer is simplified. Also, instead of writing interference fringes, amplitude information is written in dots on the red photosensitive layer, so a color hologram without a ghost image is formed.Is done.
[0085]
  Hereinafter, other application examples of the present invention will be described.
[0086]
  In the first and second embodiments described above, the example of producing the stereoscopic image print from the silver salt film has been described. However, the recording medium for producing the stereoscopic image print is a photosensitive material containing an organic dye, photo It can also be composed of heat-sensitive recording materials such as polymers and heat-sensitive paper.
[0087]
  In the first embodiment, the example in which the ultraviolet photosensitive layer is exposed with an ultraviolet laser light source and developed to change the refractive index and thickness to record phase information has been described. However, the phase modulation layer has an optical path length. It is only necessary that the phase can be modulated by the change, and it is sufficient that at least one of the refractive index and the thickness changes according to the exposure intensity. Therefore, the layer for recording phase information includes a material whose thickness changes according to the exposure intensity, a material whose refractive index changes according to the exposure intensity, and a material whose both thickness and refractive index change according to the exposure intensity. Can be used.
[0088]
  For example, the refractive index can be changed without changing the thickness of the ultraviolet photosensitive layer due to the multiphoton absorption effect. In order to obtain a multiphoton absorption effect, it is effective to use an ultrashort pulse laser having an optical pulse width of about 3 femtoseconds to about 100 picoseconds as an exposure light source. The phase information recording layer includes a dye that absorbs light having a wavelength that is not absorbed by the RGB layer, and may be any layer that can be exposed by light having an absorption wavelength of the dye, and is not limited to the ultraviolet photosensitive layer. . The light having a wavelength that does not absorb in the RGB layer may be any of ultraviolet light, infrared light, and visible light.
[0089]
  In the first and second embodiments described above, an example in which a projection image is obtained by a laser projector or the like using a transmission type stereoscopic image print has been described. However, a metal thin film such as aluminum is provided on the support side of the film. By pasting, it can also be used as a reflective stereoscopic image print. In addition to displaying a three-dimensional image, the three-dimensional image print can be used as an optical modulator in optical information communication, and can also be used as a phase wavefront distortion compensation film for light using only a phase modulation layer. .
[0090]
  In the first and second embodiments described above, an example in which a film is scanned and exposed with laser light has been described. For example, laser light with an expanded beam diameter can be converted into spatial light such as liquid crystal or a micromirror array. Modulation is performed using a modulator, and a predetermined area of the film may be simultaneously exposed (surface exposure). In addition, a light emitting element array other than a laser such as an EL (electroluminescence) element array may be used. By performing the surface exposure, the exposure time is shortened and the exposure accuracy is improved.
[0091]
  In the first and second embodiments, the example in which the amplitude information is recorded by laser exposure has been described. However, the amplitude information can also be recorded by applying an amount of ink corresponding to the amplitude information. Can do. The ink is obtained by dissolving or dispersing a color material (dye or pigment) in a solvent. As an application method thereof, for example, there is a method of forming an ink layer by ejecting ink from the head of an ink jet printer. In addition, amplitude information is used even when fixing a toner in which a pigment is dispersed in a resin binder by xerography, or in the case of forming a cured resin layer by photocuring a photocurable resin in which a pigment is dispersed in a resin. Amplitude information can be recorded by applying an amount of pigment according to the above.
[0092]
  In the case of forming an ink layer using an ink jet printer,FIG.As shown in FIG. 4, phase information is recorded for each small region in the ultraviolet photosensitive layer 44B of the silver salt film 10B by using the silver salt film 10B in which the ultraviolet photosensitive layer 44B is laminated on the support 36B. . By developing the silver salt film 10B, the ultraviolet photosensitive layer 44B becomes a phase modulation layer that controls the phase of transmitted light by changing the thickness and refractive index (optical path length) according to the exposure intensity of ultraviolet light.
[0093]
  After the development processing, ink of any one of CMY colors is applied on the above phase modulation layer for each small area from the inkjet head 53 to form an ink layer 54 having a predetermined color distribution. At this time, by controlling the ink ejection amount and changing the ink amount to be applied for each small area, that is, the ink amount to be applied per unit area, the transmission wavelength is controlled according to the ink color and according to the ink amount. A large number of small area filters for controlling the light transmittance are formed.
[0094]
  Therefore, when the silver salt film 10B on which the ink layer 54 is formed is irradiated with white light from the support 36B side, the phase of the transmitted light is modulated according to the exposure amount by the phase modulation layer (the developed ultraviolet photosensitive layer 44B). The ink layer 54 absorbs RGB light at different rates for each small region, selects the transmission wavelength, modulates the amplitude, and emits the transmitted light. As a result, a full-color stereoscopic image is reproduced. If the amount of ink increases, the light transmittance may decrease and the image may become dark. Therefore, it is possible to make only the phase modulation layer transmissive and the ink layer reflective.
[0095]
  In the first and second embodiments, the example in which the laser beam is scanned by the polygon mirror has been described.FIG.As shown in FIG. 3, the three-dimensional image printer is exposed to the four-color laser light source 22R, the green laser light source 22G, the blue laser light source 22B, and the ultraviolet laser light source 22UV, and the silver salt film 10 in the arrow C direction. You may comprise with the exposure head 58 which carries out scanning exposure. Each of the laser light sources 22R, 22G, 22B, and 22UV is coupled to an input end of a corresponding optical fiber 56R, 56G, 56B, and 56UV, and each of the output ends of the optical fibers 56R, 56G, 56B, and 56UV is It is held by the exposure head 58. In addition, about the same component as 1st Embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted.
[0096]
  In this exposure unit, the laser light emitted from the red laser light source 22R is intensity-modulated by an optical modulator (not shown) driven by a modulation driving device (not shown) based on the amplitude information of the R color, and the intensity-modulated laser. The light is coupled to the input end of the optical fiber 56R. Similarly, the laser light output from each of the laser light sources 22G, 22B, and 22UV is coupled to the input ends of the corresponding optical fibers 56G, 56B, and 56UV.
[0097]
  Since the exposure head 58 is reciprocated at a predetermined speed in the direction of arrow C by a head driving unit (not shown), the surface of the silver salt film 10 is made of optical fibers 56R, 56G, 56B, and 56UV held by the exposure head 58. Main scanning is performed in the direction of arrow C (film width direction) by laser light emitted from the output end. Moreover, the silver salt film 10 is conveyed in the predetermined direction by the conveyance roller 14, and is sub-scanned in the direction opposite to the conveyance direction. In this way, the silver salt film 10 is scanned and exposed by the laser beam, and a latent image corresponding to the image data is recorded. The head driving unit is controlled by the computer 28 in synchronization with exposure.
[0098]
  In this exposure unit, each laser light source and the exposure head are coupled with an optical fiber, and the exposure head is driven to scan and expose the silver salt film. Therefore, the configuration of the exposure unit is simplified and the apparatus is downsized. Can do. In addition, by using a fiber probe for the exposure head and exposing with near-field light, it is possible to write minute dots having a size of about 10 nm to an exposure wavelength.
[0099]
  In addition, since the above-described stereoscopic image printer can perform laser drawing directly on a film, for example, for transferring a high-definition digital image to a negative film or a positive film, for applications other than creating a three-dimensional photograph (stereoscopic image print) Can also be used. As a result, for example, it is possible to add a specific character or character on the photographed positive film with high resolution, or to write an animation character on a negative film and print it as a photograph.

A first photosensitive layer in which phase information is recorded by changing the optical path length of each small region by exposure based on phase information for each small region of the image data and development after the exposure;
The second photosensitivity in which the transmittance is changed to form a red filter and the red amplitude information is recorded by the exposure based on the amplitude information for each small area corresponding to the red color of the image data and the development after the exposure. Layers,
A third photosensitivity in which a green filter is formed by changing the transmittance by exposure based on amplitude information for each small area corresponding to green of the image data and development after the exposure, and green amplitude information is recorded. Layers,
The fourth photosensitivity in which the blue light filter is formed by changing the transmittance by the exposure based on the amplitude information for each small region corresponding to the blue color of the image data and the development after the exposure, thereby forming a blue filter. Layers,
Is a three-dimensional image recording film laminated.
