Description

  The present invention relates to a stereoscopic image display device, and more particularly, to a stereoscopic image display device capable of observing a favorable stereoscopic image regardless of changes in observation conditions and illumination environment.

  Various methods for stereoscopic display have been researched and developed in the past, and as a stereoscopic image display device, not only when the viewer's viewpoint moves in the horizontal direction, but also when it moves in the vertical direction, It is known that it is necessary to use an integral photography method, or a light reproduction method that is technically related to it. It is said that this integral photography requires a special lens called a fly-eye lens with a structure similar to an insect compound eye.

  On the other hand, instead of the fly-eye lens described above, by using a pinhole array created by printing on a transparent OHP sheet with an ink jet printer, only an easily available equipment such as an ink jet printer or a personal computer is used. It has also been proposed to perform three-dimensional display of the system (Non-patent Documents 1 and 2).

  A simple three-dimensional display method in which the integral photography fly-eye lens described in Non-Patent Document 1 is replaced with an inkjet pinhole array is used between two transparent OHP sheets printed with a pattern made by a personal computer. When a transparent thin plate is sandwiched and illuminated from the back, a stereoscopic image can be observed from the front. As a method of creating stereoscopic data, a method of ray tracing using a computer program and a method of controlling the position of a viewpoint using existing CG software (POV-Ray) have been proposed.

  One specific proposal is to sandwich a transparent plate with a thickness of about 1 mm between two OHP sheets. The upper OHP sheet has a pinhole array, and the lower OHP sheet has an original 3D image. Each pattern is printed, and when viewed from above with a backlight from below and viewed from above, stereoscopic viewing is possible.

  The principle of this method is similar to ray tracing used in pinhole cameras and computer graphics. The light emitted from the lower OHP sheet passes through the hole (pinhole) in the upper OHP sheet and reaches the viewpoint. The viewer feels as if the light is coming from an object that exists in a three-dimensional space and can be viewed stereoscopically.

  In this method, the method of creating a pattern to be printed on the OHP sheet is technically important, and the upper OHP sheet is a pinhole array by an ink jet method, and this is a very regular pattern, so it is easy to program by Pasoncon Can be generated.

  The stereoscopic display method described in Non-Patent Document 2 uses 3DCG software for a stereoscopic image display image obtained by 720 dpi output by an inkjet printer and a stereoscopic image display image obtained by 400 dpi output by a silver halide photographic printer. The principle of integral photography using this printing technology is described as follows based on FIG. 1.

  As shown in FIG. 1, a pinhole array is printed on the upper transparent sheet, and an IP image is printed on the lower transparent sheet, respectively, so that the distance between the two transparent sheets is kept constant. A transparent plate is inserted. In order to illuminate the IP image, a backlight (observation light) is placed under the IP image.

  The observer sees the light that has passed through the pinhole array. At that time, it cannot be distinguished whether the light entering the right eye has come out from the point Q of the IP image or from S on the three-dimensional object. Similarly, it cannot be distinguished whether the light entering the left eye has come out from the point R of the IP image or from S on the three-dimensional object. Therefore, the binocular parallax makes it appear as if there is an object at the point S. The pinhole array may be exchanged for a stereoscopic image display image in FIG. 1, and if the backlight (observation light) uses reflected light instead of transmitted light, the observer side There may be. Such integral photography has an advantage that a stereoscopic image can be easily obtained. Furthermore, there is an advantage that a three-dimensional image having a relatively high image quality can be obtained by the silver salt image.

However, in the method using the IP stereoscopic image, a problem has been found that the stereoscopic effect varies depending on the observation situation as a drawback when a micro light source array such as a pinhole or fly-eye lens is used.
In order to obtain the best possible stereoscopic effect, it is necessary to finely divide the micro light source array, make the IP stereoscopic image more dense, and adjust the 3D image processing appropriately. In order to realize these, it is necessary to have skill in how to adjust the 3D image processing according to the micro-processing technique and the target image scene, and labor costs are also increased.
Therefore, in the system using IP stereoscopic images, a new problem has been found that achieves an image with good stereoscopic effect even if the observation situation changes without increasing processing costs and labor costs. .

  In the present invention, the “stereoscopic image display image” is a plurality of still images, and a stereoscopic image display image for obtaining a pseudo moving image, such as when the observer moves and looks like a pseudo moving image. including. The “moving image display” is not limited to a so-called television, but includes a moving image display such as a digital display clock or a speedometer display instrument. That is, for a collection of light emitters as a stationary body, such as a display device for acoustic equipment (see FIG. 8) to be described later, or an instrument such as a vehicle, for example, a speed display display of a speedometer (see FIG. 9). This includes the case where the light emitters assembled by repeating ON / OFF of the current display moving images.

  As a result of studies by the present inventors, it has been found that the stereoscopic effect changes depending on the balance between the light of the backlight to the micro light source array such as a pinhole and the light of the environment at the time of observation. Therefore, in the present invention, by adjusting the backlight luminance according to the illuminance of the environment, an image with a good stereoscopic effect can be obtained even when the observation conditions change. Even if there was no fine processing or special image processing, it was quite surprising that a good stereoscopic image was obtained at low cost.

Conventionally, in the IP stereoscopic image system, there is no document that discloses that the backlight luminance is adjusted according to the ambient illuminance.
In addition, in a system using IP stereoscopic images, the effect of obtaining a favorable stereoscopic image at a low cost without special processing even if the environmental conditions change can be obtained because the relationship between the ambient illuminance and the backlight luminance affects the stereoscopic effect. This is unique to the present invention.

In particular, according to the invention described in claims 3, 21 to 24, a necessary part of a micro light source array such as a pinhole or fly-eye lens is displayed in two dimensions, for example, a part of the micro light source array such as a pin hole or the like. By removing (deleting) the light from the backlight (moving light emitter) and using it as a moving image for image information, the backlight (moving light emitter) can be used without adding components such as needles. It is possible to display a stereoscopic image in combination with a moving image display.
For example, an LED is used for the backlight (moving picture light emitter), white light is generated as a whole in the three-dimensional part, and the moving picture part is an LED image display with black and white movement or a color display. I came up with an idea. With such a configuration, a stereoscopic image display device can be obtained without increasing the number of devices, increasing costs, or increasing failures.

In the apparatus using the IP stereoscopic image system, there is no disclosure that discloses that a part is made a moving image and a backlight (moving light emitter) is partially used for moving image display.
In addition, in a system using IP stereoscopic images, the backlight (moving light emitter) portion is used to display a portion of the moving image at a low cost, and the efficiency of the display is reduced. Being able to get a lot of videos was an epoch-making thing.

According to the first, second, and fourth to eleventh aspects of the invention, it is possible to observe a good stereoscopic image regardless of changes in the observation state.

Since light is used, it has an excellent effect on stereoscopic effect.

According to the twenty-fourth aspect of the present invention, the present invention can be solved in spite of an inexpensive configuration.

The present invention will be described below.
In the present invention, a stereoscopic image display image is formed of a color material containing a dye or a dye precursor. When the micro light source array is a pinhole array, it may be formed of a color material containing a dye or a dye precursor, may be formed by an ink jet method, or may be formed by a printing method. Any of the known methods may be used.
First, the case where the micro light source array is a pinhole array will be described.

Examples of the color material include the following.
First, a silver halide color photographic light-sensitive material is exemplified. As the photosensitive material, any known material may be used as long as it has at least three kinds of photosensitive layers having different absorption wavelength regions from each other on a light transmissive support or a reflective support. It is preferably a transmitted light observation type silver halide color photographic light-sensitive material on which an image is formed on a light-transmitting support.

  The silver halide light-sensitive material used in the present invention may be a color negative film for photography or a color positive film, and may be either a printing paper for printing or a transmission printing film for display. One preferred embodiment of the silver halide light-sensitive material that can be used in the present invention is a large-size color positive film. Another aspect is a color film for creating a transmissive display, and a display film suitable for digital exposure is particularly preferable.

The composition of the silver halide emulsion that can be used in the present invention has an arbitrary halogen composition such as silver chloride, silver bromide, silver chlorobromide, silver iodobromide, silver chloroiodobromide, and silver chloroiodide. It may be.
For example, it may be a silver iodobromide emulsion mainly used for a photographic material. Further, it may be a silver chlorobromide emulsion containing 95 mol% or more of silver chloride used for a printing light-sensitive material, and is particularly preferably an emulsion that is optimal for digital exposure with improved high illumination exposure suitability.

  The color material used in the present invention is not limited to the above, and any known material may be used as long as it is a recording material containing a dye or a dye precursor. For example, an optical recording material capable of obtaining a high-quality color image by an azomethine dye by a simple dry treatment can be mentioned. Specifically, a microcapsule enclosing a dye precursor of an azomethine dye having a specific structure; And an optical recording material in which an oil droplet containing a photopolymerization initiator and a polymerizable electrophile and a photosensitive layer containing a binder are provided on a transparent support. And what a photoinitiator is a cationic pigment | dye / anionic boron compound complex is mentioned as a preferable example.

  This image forming method using an optical recording material comprises a transparent support, a microcapsule encapsulating a dye precursor, oil droplets containing a polymerizable electrophile and a photopolymerization initiator, and a photosensitive layer containing a binder. The image is exposed imagewise, radicals are generated from the exposed photopolymerization initiator, the radicals are added to the polymerizable electrophile to initiate polymerization, and the polymerizable electrophile is image-immobilized. To do. Thereafter, the unpolymerized electrophile and the dye precursor are brought into contact and reacted by heating to obtain a dye image.

  Examples of the dye precursor used for this are listed in paragraphs [0006] to [0047] of JP-A No. 2001-13680, and can also be used in the present invention. And the description of paragraph number [0052]-[0074] can be referred similarly about the microencapsulation of a dye precursor, a polymerizable electrophile, a photoinitiator, an oil droplet, etc.

  This optical recording material combines a plurality of photopolymerization initiators having different photosensitive wavelengths and a plurality of dye precursors having different colors to form a multicolor or full-color image. For example, it is possible to obtain an optical recording material for full-color image formation by laminating three photosensitive layers that develop colors of cyan, magenta, and yellow, respectively, and have different photosensitive wavelengths. An intermediate layer may be provided between the respective layers, and a protective layer, a filter layer, and the like may be provided.

  When selecting an exposure light source, of course, a light source suitable for the photosensitive wavelength of the optical recording material is selected, but whether the image information passes through an electrical signal, the overall processing speed, compactness, power consumption, etc. You can choose in consideration.

  When recording image information via an electrical signal, a light emitting diode or various lasers may be used as the image exposure device, or various devices known as image display devices (CRT, liquid crystal display, projector). A troluminescence display, an electrochromic display, a plasma display, or the like can also be used. In this case, the image information includes an image signal obtained from a video camera or an electronic still camera, a television signal typified by the Nippon Television Signal Standard (NTSC), and an image signal obtained by dividing an original image into a large number of pixels by a scanner or the like. In addition, image signals stored in recording materials such as magnetic tapes and disks can be used.

  When exposing color images, LEDs, lasers, fluorescent tubes, etc. are used in combination in accordance with the color sensitivity of the optical recording material, but the same may be used in combination, or different types may be used in combination. Good. The color sensitivity of optical recording materials is usually R (red), G (green), and B (blue) photosensitivity in the photographic field, but in recent years, they are often used in combination with UV, IR, etc. The range is expanding. For example, the color sensitivity of the optical recording material is (G, R, IR), (R, IR (short wave), IR (long wave)), (UV (short wave), UV (medium wave), UV (long wave). ), (UV, B, G) and other spectral regions are used. The light source may also be a combination of different types such as a combination of two LED colors and a laser. The arc tube or element may be scanned and exposed using a single tube or element for each color, or an array in order to increase the exposure speed. Available arrays include LED arrays, liquid crystal shutter arrays, magneto-optical element shutter arrays, and the like.

  Further, a blue light-emitting diode that has recently made remarkable progress, and a light source combined with a green light-emitting diode and a red light-emitting diode can be used.

  As the image display device, there are a color display device and a monochrome display device such as a CRT, and a method of performing exposure several times by combining a monochrome display device with a filter may be adopted. An existing two-dimensional image display device may be used in a one-dimensional manner like FOT, or may be used in combination with scanning by dividing one screen into several. As the heating means, as in the optical recording material described in JP-A-61-294434, a heating element layer may be provided on the surface of the support on which the photosensitive layer of the optical recording material is not coated. Good. Further, a hot plate, an iron and a hot roller are used as described in JP-A-61-147244, or an optical recording material is sandwiched between the heat roller and a belt as described in JP-A-62-144166. You may use the method of heating by.

  That is, the optical recording material may be brought into contact with a heating element having a surface area equal to or larger than the area of the optical recording material, and the entire surface may be heated simultaneously, or a heating element having a smaller surface area (hot plate, heating roller, heating drum, etc. And the entire surface may be heated over time. In addition to the heating method in which the heating element and the optical recording material are in direct contact as described above, the non-contact state can be heated by applying electromagnetic waves, infrared rays, hot air, or the like to the optical recording material. In the image formation of the present invention, when the optical recording material is heated from the surface on which the photosensitive layer is not coated, the surface on which the photosensitive layer is coated is in direct contact with air. However, in order to prevent moisture and volatile components from evaporating from the optical recording material or to keep the heat from escaping, it may be covered with a heat insulating material or the like.

  The heating is preferably performed after 0.1 second or more has passed after imagewise exposure. The heating temperature is generally 60 ° C. to 250 ° C., preferably 80 ° C. to 180 ° C., and the heating time is between 0.1 seconds and 5 minutes. Moreover, you may heat twice or more at different temperature.

Next, the heat-sensitive recording material used in the present invention will be described.
The heat-sensitive recording material may be any known heat-sensitive recording material containing a dye or a dye precursor. For example, a first thermosensitive coloring layer containing an electron donating dye precursor and an electron accepting compound as main components on a transparent support, a diazonium salt compound having a maximum absorption wavelength of 360 ± 20 nm, the diazonium salt compound and heat A second thermosensitive color-developing layer containing a coupler which develops color upon reaction, a third containing a diazonium salt compound having a maximum absorption wavelength of 400 ± 20 nm, and a coupler which reacts with the diazonium salt compound to develop color A multicolor thermosensitive recording material that is formed by sequentially laminating thermosensitive color-developing layers is disclosed. Japanese Patent Publication No. 49-69 creates a thermosensitive recording material in which a plurality of electron-donating dye precursors and an electron-accepting compound coexist. An attempt was made to obtain images of different hues by applying different temperatures by utilizing the different color development start temperatures of the electron donating dye precursors. In 27708 and JP-B-51-5792, two layers of heat-sensitive recording layers that develop colors in different hues are laminated, and the upper layer is colored at low temperatures, and both the upper and lower layers are colored at high temperatures. An attempt to obtain a material was proposed. In Japanese Patent Publication No. 51-5791, a first thermosensitive coloring layer comprising a diazonium salt compound and a coupler, an intermediate layer containing a polyether compound, a basic dye precursor, A multicolor heat-sensitive recording material in which a second heat-sensitive color-developing layer composed of an electron acceptor and an electron-accepting compound is laminated has been proposed. Japanese Patent Publication No. 51-29024 discloses a heat-sensitive material composed of a basic dye precursor and an electron-accepting compound. In a two-color thermosensitive recording material in which two color-developing layers are laminated, a method in which guanidines, which are organic base compounds, are added to the low-temperature color-developing layer, and the color development of the low-temperature color-developing layer is erased when the high-temperature color-developing layer is colored Further, in Japanese Patent Publication No. 51-37542, a high temperature thermosensitive coloring layer composed of an acidic dye precursor and an organic base compound and a low temperature coloring layer composed of a basic dye precursor and an electron accepting compound are laminated on a transparent support. There has been proposed a multicolor heat-sensitive recording material in which the organic base compound in the lower layer diffuses into the upper layer and erases the color former during high-temperature printing.

  As one of the methods for reproducing a full-color image by direct thermal recording, a thermal recording layer 2 in which two diazonium salts having different photosensitive wavelengths and couplers that react with each of the diazonium salts and develop colors in different hues upon heating are combined. There is also known a heat-sensitive recording material that can reproduce a good multicolor image by laminating a layer and a heat-sensitive recording layer combining a basic dye precursor and an electron-accepting compound, and any of the above can be used in the present invention. It is.

The production of the pinhole array is preferably made of the color material, but is not limited to this, and any known method such as black and white silver halide photographic light-sensitive material, ink jet, or printing may be used.
The preferred pinhole array of the present invention preferably uses a color photosensitive material or heat-sensitive recording material as described above, and preferably has a black pinhole aperture ratio of 2 to 15%, particularly 2 to 10%, and a pinhole maximum density of 2.5 or more. In particular, exposure and development are performed by a conventional method so as to be 3.0 or more.

  In the stereoscopic image display device according to the present invention, the pinhole array and the stereoscopic image display image may be formed on the same transparent support (including a colored transparent support; the same shall apply hereinafter), They may be provided opposite to each other on the front and back surfaces of separate transparent supports. In the former case, it is necessary to stack the two images when observing the three-dimensional image. In this case, it is possible to stack the two members without the pinhole array of the support and the three-dimensional image display image so that the distance between the two images is increased. preferable. On the other hand, in the latter case, the transparent support preferably has a thickness of 1 mm to 10 mm, particularly 2 mm to 5 mm so that the distance between the two is separated.

Also for the transparent support used in the former example, a combination of transparent supports having such a thickness that the above separation distance can be obtained is used.
In the case of this former example, the preferred pinhole array and stereoscopic image display image of the present invention may be formed of the same type of color photosensitive material, or formed of different types of color photosensitive material (for example, pinhole array). May be made of a heat-sensitive recording material, and a stereoscopic image display image may be made of a silver halide color photographic light-sensitive material.

In the case of the latter example, it is preferably formed of the same type of color photosensitive material. For example, a silver halide photosensitive layer for pinhole array formation is coated on the surface side of the transparent support having the above thickness. In this case, a silver halide photosensitive layer for image formation for stereoscopic image display is coated on the back side.
In this case, the formation of the pinhole array and the formation of the stereoscopic image display image have an advantage that the image formation and the arithmetic processing can proceed in parallel.

  In the present invention, a stretchable support is used as the support, and a micro light source array such as a pinhole and a stereoscopic image display image are installed along the stereoscopic surface of the object to which the image is attached. The stereo image reproduction according to the present invention may be performed on a stereo (music) plane. In this case, the stretchable support is preferably a transparent support. Preferred examples of the stretchable transparent support include low density polyethylene and polyvinyl chloride film supports. In order to match the relative position of the micro light source array and the stereoscopic image display image, a micro light source array such as a pinhole is provided on one side of a stretchable transparent support, and the stereoscopic image display image is provided on the opposite side. Then, it is more preferable to expand and contract in accordance with the pasting surface and maintain the relative position because the stereoscopic image is retained even when expanded and contracted.

The pinhole array is preferably in the form of a grid, for example, configured by 240 units × 240 units, and further, one unit has a configuration of 64 pixels × 64 pixels, and the aperture ratio of the pinhole is unexposed in one unit of 64 pixels. A pinhole array having an aperture ratio of 11.8% and a maximum density of 2.5 can be obtained by adjusting the size of the transparent pixel area and securing a transparent pixel area of 22 pixels × 22 pixels.
Here, the maximum density refers to the maximum value of visual density obtained by measuring the black region with X-Rite.

  A method of creating a stereoscopic image display image may be a ray tracing method using a specific computer program, but a known technique such as a method using a commercially available CG application may be employed. In particular, in the present invention, the stereoscopic image display image uses a plurality of rendering images with different viewpoints by 3DCG software in the image data creation step, or the stereoscopic image display image is in the image data creation step. A plurality of rendering images with different viewpoints by CAD software can be used.

  A plurality of rendering images with different viewpoints created as described above can be combined and rearranged by an arbitrary method to form a stereoscopic image display image. For example, the method described in Non-Patent Document 2 is preferable.

  Arbitrary software can be used for 3DCG software in the present invention. Examples of software that is easily available on the market and that is preferable in terms of quality include shade, Maya, 3D studio max, soft image, light wave 3D, and cinema 4D.

  The transparent support in the present invention is not particularly limited as long as it has transparency in the visible light region, and those known in the photographic industry can be adopted. The transparent support need not be a single layer and may be a laminate.

The micro light source array of the present invention is not limited to the pinhole array described above.

Specifically, white light is obtained by color mixing of light, and is a mixture of blue light emitted from an InGaN-based LED having a wavelength of 450 to 550 nm, which is a light source, and yellow light emitted from a phosphor. As a phosphor suitable for such a white LED, for example,
Composition formula: (Y, Gd) ₃ (Al, Ga) ₃ O ₁₂
A phosphor in which Ce is doped into a YAG-based oxide represented by the following is most often used. This phosphor is thinly coated on the surface of an InGaN blue LED chip, which is a light source, and emits white light. Such a white light source may be used in the present invention.

  Next, in the present invention, for example, a light emitting device having a light emission wavelength in the range of 360 nm to 550 nm and an oxynitride phosphor in which a rare earth element is activated, a part of the light of the light emitting device is A white light source that is wavelength-converted and emitted by a phosphor may be used, and an emission wavelength of the light-emitting element is in a range of 450 nm to 550 nm.

A white LED having this structure is preferable because of its excellent high-quality stereoscopic image color reproducibility.
The white light source as the observation light used in the present invention is commercially available and is also available from the market. For example, the ultraviolet LED is known as TG Purple of Toyoda Gosei Co., Ltd. The white LED has been marketed by the company as a high brightness white LED “TG TRUE White Hi”, and these can also be used in the present invention.

For example, the micro light source array, the stereoscopic image display image, or an arbitrary position is provided. Any of a transparent protective layer and an intermediate layer may be used. In the present invention, such a constituent member is particularly preferably provided on the observation side with reference to the stereoscopic image display image. That is, it is preferable to contain the above compound in a transparent protective layer or the like provided on the observation side of the stereoscopic image display image.

  Moreover, in this invention, it is preferable to have structural members, such as a three-dimensional image display image, the observation side transparent protective layer, and the backlight side transparent protective layer.

FIG. 2 shows a principle diagram of the integral photography of the present invention.
In FIG. 2, the color material is formed on a transparent support with three photosensitive layers having different absorption wavelength ranges through an intermediate layer [blue-sensitive yellow coloring layer (B layer), green-sensitive magenta coloring layer. (G layer), red-sensitive cyan coloring layer (R layer)] are coated in a layered manner [a layer for forming a stereoscopic image display image (IP image) by exposure and development. ], A protective layer is laminated on the outermost layer. On the other hand, the fly-eye lens is formed by patterning light condensing elements on a transparent support by a printing method or an inkjet method. By the color material, a stereoscopic image display image (IP image) is obtained, and the two transparent supports are laminated. Note that an intermediate transparent plate as shown in FIG. 1 may be interposed between two transparent supports.

  When a protective layer is provided, based on the color material (stereoscopic image display image), the backlight-side protective layer A (transparent protective layer provided at a position separated from the color material) or the protective layer B (color material) Transparent protective layer constituting the color material), observer side protective layer C (transparent protective layer constituting the color material) and protective layer D (transparent backing layer or color material constituting the color material) Any of a separate transparent protective layer) and a protective layer E (a transparent protective layer closer to the viewer than the smile light source array) may be used. The device according to the present invention is covered with a light-shielding device body.

  As the moving picture light emitting body preferably used in the present invention, a known moving picture display light emitting device can be adopted without particular limitation, and a liquid crystal display (LCD), a plasma display (PDP), an electroluminescent display (ELD), or the like is used. Can do. For example, in the case of an LCD that is a light receiving type (non-light emitting type) display, the liquid crystal panel has a display area composed of a plurality of pixels, and each pixel has a red R (Red) area and a green G (Green) area. , And a blue B (Blue) region. Specifically, a red filter, a green filter, and a blue filter are provided corresponding to these regions, respectively, and the RGB components of white light from the backlight unit are selectively transmitted by these filters. In the LCD, the voltage applied to the liquid crystal cells corresponding to the RGB regions of each pixel is controlled to adjust the balance of the RGB components of light, thereby realizing a full color display.

  On the other hand, a PDP which is a light-emitting display has discharge cells corresponding to RGB regions of each pixel. For example, in a discharge cell arranged corresponding to an R region, ultraviolet light generated by discharge is converted into red fluorescence. Emits red light when excited by irradiation of the body. In the PDP, the light emission luminance of the discharge cells corresponding to the RGB regions is controlled to adjust the balance of the RGB components of the light, thereby realizing full color display.

  Such a moving image display light emitting device can be used for various purposes such as a time display of a vehicle or the like, a meter display of a vehicle or the like, a warning display, and a display of navigation information from a car navigation system. It is one of the features of the present invention that the moving picture light emitter is used as a backlight (observation light) of an IP stereoscopic image by the integral photography technique.

Specific examples of a moving image display light emitting device (moving light emitter) include an LED as a light source, an acrylic light guide plate that guides light from the light source, and light leaked from the light guide plate to the lower portion of the light guide plate. Examples include a reflecting sheet that reflects light, a diffusion sheet that is disposed above the light guide plate in order to reduce unevenness in brightness, and a unit that includes a prism sheet that is disposed on the diffusion sheet in order to improve brightness.
As the moving image display light emitting device (moving image light emitter) used in the present invention, a plasma display (PDP) or an electroluminescent display (ELD) which is a light emitting display can also be used.

The present invention has a plurality of luminance modes of a light emitter that functions as a backlight, and has at least a daytime mode and a nighttime mode, and the luminance mode can be changed manually or automatically.
In the case of automatic, the brightness is adjusted when the brightness is below the threshold value of the illuminance detector. Night mode reduces brightness (see FIGS. 5 and 6).

  Further, providing the antireflection means on the display body surface improves the stereoscopic effect. The antireflection means may be any known one such as a matte film or an antireflection film.

  The device 1 according to the present invention is a display device capable of observing the IP stereoscopic display 2, provided with a display hood 3, and can be adjusted so that the viewing angle θ from the observer is within 10 degrees. Thus, it is preferable to provide the device 1 according to the present invention with a known angle viewing angle adjusting means 4 (see FIG. 7).

In the present invention, a stereoscopic effect can be obtained by setting the maximum perceived depth of an image to 10 cm to 100 cm. In this regard, the depth range that can be displayed on a stereoscopic display is limited, but the depth visible in any particular scene can cover almost any range. Thus, there is a need for techniques to control the mapping from the physical scene depth to the perceptual display depth, for example, when taking a stereoscopic photograph or generating a stereoscopic computer graphic image (ie, computer simulation).
This technique is disclosed in, for example, Japanese Patent Laid-Open No. 2001-148869, and this technique can also be adopted in the present invention.

For example, as shown in FIG. 6, the brightness adjusting means used in the present invention displays the normal mode (daytime mode) (display of the IP stereoscopic image in FIG. 3) by the power input of the apparatus, and is detected by the illuminance detecting means. The signal determines whether or not the illuminance is below the threshold. If it exceeds the threshold, the normal mode (daytime mode) continues, and if it is below the threshold, the display switches to night mode. (Display of the IP stereoscopic image in FIG. 5). In both the normal mode (daytime mode) and the nighttime mode, the signal is output to the illuminance detection means after a predetermined time, and the process is repeated in accordance with the detection signal.
In this example, two modes, the normal mode (daytime mode) and the night mode, have been described, but the present invention is not limited to this and may be applied to three or more mode changes.

  The present invention is an illumination device for an electronic or electromechanical device, such as a watch, including a device that displays time related information or other information, the illumination device illuminating an IP stereoscopic image. The light source itself can also measure the intensity of ambient light, or is controlled by brightness adjusting means having illuminance detection means for measuring the intensity of ambient light.

  Since the amount of backlight for the stereoscopic image display image is controlled in multiple stages or at least in the daytime mode and the nighttime mode in accordance with the environmental illuminance, the substantial display luminance by the stereoscopic image display image is controlled. The display contents can be surely seen even in bright outside light conditions, and the display contents can be surely seen without being dazzled even in dark outside light conditions. 3D display content can be surely visually recognized both in the case of the case and the case of the dark external light state.

  In the present invention, for example, a clock circuit is connected to a microcomputer for controlling the in-vehicle electronic device in a complex manner, and an indicator for performing an operation command or operation check of the in-vehicle electronic device is provided. A control circuit for increasing / decreasing the substantial display brightness is interposed between the control circuit and the control circuit to control the display of the IP stereoscopic image display in multiple steps or continuously according to the time data output from the clock circuit. As a configuration for controlling the brightness, in a dark environment such as in the evening, it is too bright and dazzling in the daytime display brightness, and it is difficult to confirm the IP stereoscopic image display content, and it is dark in the nighttime display brightness and the IP stereoscopic image display. You may employ | adopt the structure from which the brightness | luminance of the display of a display changes so that it may become difficult to see the content.

  Also, specifically, a watch main body as timekeeping means, an LED that is installed in the watch main body and emits light in response to a command signal, and the brightness around the LED is detected and output according to the brightness A CdS sensor that outputs a signal, a reflecting plate that is rotatably installed around a predetermined rotation axis in the watch body, reflects light around the watch body, and receives a command signal and rotates, and at least the watch body When the surroundings of the watch body are determined to be bright based on the output signal from the CdS sensor in conjunction with the time obtained by the unit, a command signal for rotating the reflecting plate is output to the reflecting plate. When it is determined that the image is dark, a configuration including a control circuit that outputs a command signal for causing the LED to emit light to the LED may be employed.

  In the case of manual operation, the following configuration can be adopted. That is, for example, in-vehicle electronic devices such as car audio devices and car navigation devices are equipped with various indicators, and while observing the displayed contents, various operations of the device are instructed and the operation of the device is confirmed. The desired function of the device can be executed. Such an indicator employs measures to ensure that the display contents can be visually recognized both when the vehicle is traveling in the daytime and when it is traveling at night. For example, a light switch provided on the vehicle The display brightness of the IP stereoscopic image on the display is controlled according to the output of the “daytime operation mode” and “nighttime operation mode” output in conjunction with the switch operation of do it.
