Description
- 1. Field of the Invention
- The present invention relates to an apparatus for displaying a two-dimensional picture containing a stereoscopic image and a method therefor.
- 2. Description of the Related Art
- As a way of reproducing a stereoscopic image, there is a method using polarizing glasses in which a viewer wearing the polarizing glasses observes right and left parallax images of the picture corresponding to the polarized, which are states different from each other. However, there is a troublesome disadvantage in such a method because the viewer has to wear polarizing glasses whenever he views the picture, in addition to preparation of two parallax images thereof.
- As to a method that does not use any polarizing glasses, a method for displaying a stereoscopic image using a lenticular lens is known. In such a method using the lenticular lens, a picture composed of a pair of striped images arranged alternately as right and left parallax images corresponding to right and left eyes of the viewer is displayed on the display screen. The lenticular lens is provided on the viewer's side of the display screen so as to give directivity of each stripe pixel of the parallax images toward the corresponding eye, thereby enabling the viewer to recognize a stereoscopic image. However, there is a disadvantage of the lenticular lens method in that resolution is reduced by 50% when the stereoscopic image is displayed, in addition to complicated structure thereof.
- Japanese Patent Kokai Hei 10-221644 discloses an improved apparatus for displaying a stereoscopic image with a lenticular lens which is designed to prevent unnecessary reflected light on the display screen and to reduce moire and color drift in the reproduced picture. In such a displaying apparatus, polarizing means is utilized in such a manner that a pair of polarizing plates each having polarizing stripe polarizing axes in the orthogonal direction to each other are suitably arranged alternately together with the display screen and the lenticular lens in a predetermined direction and at a predetermined pitch. The viewer can visually observe a stereoscopic image through the polarizing plate.
- In view of the foregoing descriptions, it is apparent that all of these conventional stereoscopic image display apparatuses require two parallax images corresponding to both eyes of the viewer in the beginning stage of photographing for the picture to be displayed. Therefore, the conventional stereoscopic image display apparatuses naturally demand many steps and means for supplying parallax images for the stereoscopic image.
- The present invention is made to overcome such a conventional problem and therefore an object of the present invention is to provide an apparatus for displaying a stereoscopic two-dimensional image which solves such problems and realizes the display of a stereoscopic image using a simple configuration.
- An apparatus for displaying a stereoscopic two-dimensional picture according to the present invention comprises:
- a display unit having a flat image display screen for displaying a two-dimensional picture containing a stereoscopic image; and
- an image transmitting panel placed parallel to and apart from said image display screen, the image transmitting panel having a microlens array of a plurality of lenses and an effective area larger than that of the stereoscopic image contained in said two-dimensional picture, and a lens frame area surrounding a perimeter of the effective area of said microlens array, so that said image transmitting panel generates an image-formation plane for displaying a real image of said two-dimensional picture in a space located on an opposite side to said display unit with respect to said microlens array.

The lens systems are arranged in the two-dimensional manner so that the optical axes of the lens systems are parallel to one another.
- In another aspect of the apparatus for displaying a stereoscopic two-dimensional picture according to the invention, said microlens array forms an erect real image of the two-dimensional picture.
- In a further aspect of the apparatus for displaying a stereoscopic two-dimensional picture according to the invention, said lens frame area is a dark color area.
- In still another aspect of the invention, the apparatus for displaying a stereoscopic two-dimensional picture further comprises a supporting member supporting said lens frame area and defining a distance between the image display screen and the image transmitting panel, at least an optical path side of the supporting member being a dark color.
- In a still further aspect of the invention, the apparatus for displaying a stereoscopic two-dimensional picture further comprises a picture signal supply circuit for generating a picture signal for exhibiting an image portion other than stereoscopic images which is filled with a dark color in the two-dimensional picture to be reproduced and supplying the picture signal to said display unit.
- In a further aspect of the invention, the apparatus for displaying a stereoscopic two-dimensional picture further comprises an image-formation-spot indicating unit placed adjacent to said image-formation plane.
- In still another aspect of the apparatus for displaying a stereoscopic two-dimensional picture according to the invention, said display unit comprises;
- a back-light illuminating unit;
- a color liquid crystal display panel arranged so as to completely cover a surface of the back-light illuminating unit; and
- picture signal supply unit supplying a picture signal including two-dimensional picture data and stereoscopic image data to the color liquid crystal display panel.
- In a further aspect of the apparatus for displaying a stereoscopic two-dimensional picture according to the invention, said display unit further comprises;
- a black-and-white liquid crystal panel unit arranged between the back-light illuminating unit and the color liquid crystal display panel; and
- a mask signal generating-supplying unit generating a mask signal for masking an image portion except for stereoscopic image portions to be reproduced and supplying the mask signal to the black-and-white liquid crystal panel unit.
- A method for displaying a stereoscopic two-dimensional picture according to the invention comprises the steps of:
- providing a display unit having a flat image display screen for displaying a two-dimensional picture containing a stereoscopic image;
- arranging an image transmitting panel parallel to and apart from said image display screen, said image transmitting panel having a microlens array of a plurality of lenses and an effective area larger than that of the stereoscopic image contained in said two-dimensional picture, and a lens frame area surrounding a perimeter of the effective area of said microlens array; and
- defining a relative position relationship between said image display screen and said image transmitting panel so that said image transmitting panel generates an image-formation plane for displaying a real image of said two-dimensional picture in a space located on an opposite side to said display unit with respect to said microlens array.
- In one aspect of the invention, the method for displaying a stereoscopic two-dimensional picture further comprises a step of supplying a picture signal to said display unit so as to make an image other than the stereoscopic image a two-dimensional picture in a dark color.
- In another aspect of the invention, the method for displaying a stereoscopic two-dimensional picture further comprises a step of placing an image-formation-spot indicating unit adjacent to said image-formation plane.
- In a further aspect of the invention, the method for displaying a stereoscopic two-dimensional picture further comprises a step of:
- introducing, for said display unit, a back-light illuminating unit, and a color liquid crystal display panel arranged so as to completely cover a surface of the back-light illuminating unit, and a black-and-white liquid crystal panel unit arranged between the back-light illuminating unit and the color liquid crystal display panel;

- generating a mask signal for masking an image portion except for stereoscopic image portions to be reproduced; and
- supplying the mask signal to the black-and-white liquid crystal panel unit.
- According to the present invention, by the microlens array, a erected real image contained in the two-dimensional picture is formed on the image-formation plane in a space without providing any diffuser such as a screen for a viewer looking squarely at, because the microlens array is secured so that the image display screen displaying the two-dimensional picture containing the stereoscopic image coincides with the focal surface of the micro convex lens array on the object side. As a result, a very simple configuration for the displaying apparatus realizes a stereoscopic exhibition of the two-dimensional picture containing the stereoscopic image. In addition, unlike the conventional methods, the present displaying apparatus does not require any polarizing glasses nor plates without deteriorating the resolution of the stereoscopic image.
- The present displaying apparatus for a stereoscopic image can be configured easily by combining a two-dimensional (flat) display therewith, because a microlens array is comparatively low in price and suited for mass production.

- Several embodiments of apparatuses for displaying a two-dimensional picture containing a stereoscopic image according to the present invention will be described below with reference to the accompanying drawings.
- FIG. 1 is a sectional view of an apparatus for displaying a two-dimensional picture containing a stereoscopic image as a first embodiment. The apparatus comprises a
display unit 10 such as a color liquid crystal display device (LCD) and animage transmitting panel 20 supported by a supportingmember 15 which is fixed to the display unit. Theimage transmitting panel 20 generates an image-formation plane 30 in a space located on the opposite side of the LCD. - The
display unit 10 includes a flat image display screen for displaying the two-dimensional picture containing the stereoscopic image. The display unit is not limited to an LCD. For example, a CRT, a plasma display, or an organic electroluminescence display is also usable for the display unit in place of the LCD. In the case where thedisplay unit 10 is an LCD, the LCD comprises a color liquidcrystal display panel 10 a having a flat image display screen, a back-light illuminating unit 10 b, and a color liquidcrystal drive circuit 10 c connected to the liquidcrystal display panel 10 a and driving it. Thedrive circuit 10 c is connected to a picturesignal supply unit 11 which supplies a picture signal for the two-dimensional picture containing the stereoscopic image. - The
image transmitting panel 20 comprises amicrolens array 22 and alens frame area 23, for example, a lens frame surrounding an effective area of the microlens array. The supportingmember 15 supports thelens frame area 23 and defines a distance between the image display screen and the image transmitting panel. Theimage transmitting panel 20 is located parallel to and apart from the image display screen of the color liquidcrystal display panel 10 a. Themicrolens array 22 is an erecting optical system in which the stereoscopic two-dimensional picture appearing on the image display screen is transmitted to a front space as a real image whose spatial orientation and size are substantially identical to that of the picture to present the real image to the view. Themicrolens array 22 has an effective area larger than that of the stereoscopic image contained in the two-dimensional picture. In this embodiment, the effective area of themicrolens array 22 is the same as the area of the image display screen of the color liquidcrystal display panel 10 a. Thelens frame area 23 is in a dark color such as black so as to make the existence of the microlens array less conspicuous to the viewer. - The
microlens array 22 comprises a plurality of microlenses arranged two-dimensionally. As is shown in FIG. 1, themicrolens array 22 is a micro-convex-lens board formed by integrating every pair of lens-array half bodies 24 with a spacer. The micro-convex-lens board is formed of a plurality of lens systems. Each lens system includes of a pair of convex lenses coaxially arranged in the optical axes thereof. The lens systems are arranged in a two-dimensional manner so that the optical axes of the lens systems are parallel to one another. FIG. 2 is a sectional view of themicrolens array 22 sectioned at a plane containingoptical axes 26 of eachconvex lens 25. Theconvex lens 25, which is formed on the right side face of the lens-array half body 24 shown on the right side of the figure, has a curvature larger than that of other convex lenses. Distance L2, which is the distance between the focus of the lens-array half body 24 on the image side (image-formation plane 30) shown on the right side of the figure and the lens surface, is longer than distance L1, which is the distance between the color liquidcrystal display panel 10 a of the lens-array half body 24 shown on the left side of the figure and the lens surface. Accordingly, the image-formation plane 30 is sufficiently distant from theimage transmitting panel 20, making it possible for the apparatus to display a compact image by reducing the depth thereof. As shown in FIG. 2, eachconvex lens 25 has the same quality of material and shape. For example, theconvex lenses 25 are formed to align adjoining each other in the form of a matrix on a transparent flat plate. Theoptical axis 26 of theconvex lens 25 coincides with each other between a pair ofadjacent half bodies 24 of the lens array. Although the material of theconvex lens 25 and the transparentflat plate 27 is acrylic resin, the transparent flat plate may be made of glass. - The operation of the apparatus embodiment to display an image will be described below.
- As shown in FIG. 3, the
LCD 10 is arranged on a darkcolored stage 19, such as a black color. TheLCD 10 has a color liquidcrystal display panel 10 a for displaying a two-dimensional picture containing a stereoscopic image, with aperimeter 10 d which is colored black. Supporting plates, being the supportingmember 15, are fixed perpendicularly on the perimeter of the color liquidcrystal display panel 10 a of theLCD 10 so as to screen the field of vision in the horizontal direction. The supportingmember 15, too, at least the inside thereof on the side of the color liquidcrystal display panel 10 a, is colored black. Provided on the free end of the supporting plates are carryunits 15 a at the lower end thereof, andspring units 15 b at the upper part thereof, which are able to impart springiness in the horizontal direction opposing each other. - The
lens frame area 23 of theimage transmitting panel 20 is inserted in the clamped manner between thespring units 15 b, and the image transmitting panel is mounted on thecarry units 15 a so as to be arranged parallel to and apart from the image display screen of theLCD 10. Because thelens frame area 23 is black, the supportingmember 15 is concealed from the viewing side. The image display screens of theimage transmitting panel 20 and theLCD 10 are previously arranged in a physical relationship wherein the image display screens are made to coincide with the focal surface of themicrolens array 22 on the object side. In this manner, when the image of an object (stereoscopic image) is formed on the image display screen of theLCD 10, the image is formed on the focal surface on the image side, enabling a real image of the stereoscopic image to be viewed from the substantial optical axis direction. In this case, the side of the image display screen is the object side because the reproduced image is obtained from the stereoscopic image formed on the image display screen of theLCD 10. - The two-dimensional picture containing the stereoscopic image to be displayed can be perceived as a three-dimensional image, if the image other than the stereoscopic image such as the background is filled with a dark color such as black by using a known picture-signal processing method for bracketing the stereoscopic image according to the luminance level or color level. Such a processing makes only the stereoscopic image to be displayed (real image) seen to be standing out toward the viewer, because the stereoscopic image surrounded by a dark color such as black, of the
perimeter 10 d of the color liquidcrystal display panel 10 a and the inside of the supportingmember 15. As the subject of a stereoscopic image, a dynamic body such as a moving animal or vehicle is preferable to a static body. - Furthermore, the apparatus for displaying a stereoscopic two-dimensional picture may also include an image-formation-spot indicating unit i.e., a
real body 31 placed adjacent to the image-formation plane. By arranging thereal body 31, a viewer can stereoscopically perceive a stereoscopic two-dimensional picture, though he does not receive any parallax image information. Thereeal body 31 is placed in the neighborhood i.e., before and behind the image-formation plane 30 with a real image P of the stereoscopic image generated thereon so as not to obstruct the optical path. Thereal body 31 near the real image P is to give the viewer an illusion as if the two-dimensional picture were a real three-dimensional image. - In the first embodiment above, the description has been given of the case wherein the
image transmitting panel 20 is fixed to the perimeter of the color liquidcrystal display panel 10 a of theLCD 10 in a freely demountable manner with the supportingmember 15. In addition to the first embodiment, FIGS. 4 and 5 show a second embodiment. It is possible to replace the supportingmember 15 by anintegral housing 40 as an expanded supporting member. Theintegral housing 40 surrounds the optical path and supports the side of theimage transmitting panel 20. The internal surface of thehousing 40 is colored a dark color such as black at least on the side of the optical path. It is preferable to make the width of the display screen of the color liquidcrystal display panel 10 a nearly equal to an effective width of themicrolens array 22 , that is, to make the effective areas of both almost the same. In order to realize this state, slitunits 41 respectively corresponding to the thickness of theimage transmitting panel 20 and the color liquidcrystal display panel 10 a are provided inside theintegral housing 40, and each of them is inter-fitted so as to be fixed apart from each other by a predetermined distance. Owing to this configuration, it is unnecessary to color thelens frame area 23 in the perimeter of themicrolens array 22 black. Instead, afront face 40 a of thehousing 40 is colored a dark color. It is also possible to provide acircuit housing unit 43 inside theintegral housing 40 on the side of the back face of the color liquidcrystal display panel 10 a so as to house the drive circuit and other parts. A compact apparatus for displaying a stereoscopic image is realized with the configuration described above. - In a third embodiment, the picture
signal supply unit 11 of the apparatus for displaying the stereoscopic two-dimensional picture may include an electric circuit for generating a modified picture signal for exhibiting an image portion other than stereoscopic images which is filled with a dark color in the two-dimensional picture to be reproduced and then supplying it to the drive circuit and the display unit so as to form only the stereoscopic image. - In a fourth embodiment, the
display unit 10 can comprise a back-light illuminating unit 10 b, a color liquidcrystal display panel 10 a arranged so as to cover the whole surface of the back-light lighting, and a black-and-white liquidcrystal panel unit 12 arranged between the back-light illuminating unit 10 b and the color liquidcrystal display panel 10 a, as shown in FIG. 6, in addition to the first embodiment. In this case, the apparatus for displaying a stereoscopic two-dimensional picture includes a black-and-white liquidcrystal drive circuit 10 f connected to the black-and-white liquidcrystal panel unit 12 and a mask signal generating-supplyingunit 10 g connected to the black-and-white liquidcrystal drive circuit 10 f. The mask signal generating-supplyingunit 10 g is connected to the picturesignal supply unit 11 for supplying a picture signal including two-dimensional picture data with stereoscopic image data contained therein. The mask signal generating-supplyingunit 10 g generates a mask signal for masking an image portion except for stereoscopic image portions to be reproduced from the picture signal on the basis of the supplied data from the picturesignal supply unit 11, and supplies the mask signal to the black-and-white liquidcrystal drive circuit 10 f. With this embodiment configuration, when the color liquidcrystal drive circuit 10 c drives the color liquidcrystal display panel 10 a so as to form an original picture i.e., the two-dimensional picture containing the stereoscopic image, then the black-and-white liquidcrystal drive circuit 10 f simultaneously drives the black-and-white liquidcrystal panel unit 12 so as to mask an image portion except the stereoscopic image corresponding to the mask signal, for example, a background image. Consequently, the two-dimensional picture containing the stereoscopic image to be displayed can have images such as background images colored dark, such as black, except for the stereoscopic image. - In a fifth embodiment, instead of the black-and-white liquid
crystal panel unit 12 and thedrive circuit 10 f of the fourth embodiment, amask processing circuit 10 h connected to the picturesignal supply unit 11, the mask signal generating-supplyingunit 10 g and the color liquidcrystal drive circuit 10 c may be provided with the apparatus as indicated by dotted lines shown in FIG. 6. The mask signal generated in the mask signal generating-supplyingunit 10 g is supplies to themask processing circuit 10 h as indicated by a dashed arrow shown in FIG. 6. Themask processing circuit 10 h generates a picture signal for a picture masked except the stereoscopic image part on the basis of the supplied signals from the picturesignal supply unit 11 and the mask signal generating-supplyingunit 10 g, and supplies the generated picture signal to the color liquidcrystal drive circuit 10 c. - It is understood that the foregoing description and accompanying drawings set forth the preferred embodiments of the invention at the present time. Various modifications, additions and alternative designs will, of course, become apparent to those skilled in the art in light of the foregoing teachings without departing from the spirit and scope of the disclosed invention. Thus, it should be appreciated that the invention is not limited to the disclosed embodiments but may be practiced within the full scope of the appended claims.
