Abstract

PROBLEM TO BE SOLVED: To display a picture of different integrating picture body without making a user hold or tilt the pictures, by providing a supporting section which holds the body, that supports first and second integrated pictures, in a base section so that the body faces forward. SOLUTION: The integrated picture body 4 has at least first and second integrated pictures which are viewed from different angular positions with respect to the body. The body 4 is held by a slender slot 14 provided on a supporting section 12 (which forms a base section 10). The section 12 has a convex face buttom section surface 16 in its bottom section, a slender stopping section 18 in its front end section and a different slender stopping section 20 at its back end section. An assembly 2 is placed on a horizontal surface 40. The user tilts the section 12 by hand from the stopping position to the front or to the back until the section 18 (20) touches the surface 40. If the user takes away his hand, the section 12 repeatedly rocks to the front or to the back in the direction indicated by an arrow 33 about the stopping position as a center and different pictures of the body 4 are repeatedly projected.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display assembly for displaying an integral image element capable of displaying depth, motion, and other images.

[0002]

2. Description of the Related Art As a conventionally known integral image body, a lenticular lens sheet, a fly-eye lens sheet or a barrier strip sheet and a three-dimensional integral image aligned with these lens sheets are used to form a device such as special glasses. Some can observe a three-dimensional image without using it. Such an image forming body and its structure are described in "Three-dimensional image technology" by Takanori Okoshi (Academic Press, New York, 1976 edition). An integral image element having a lenticular lens sheet (a sheet having a plurality of adjacent, parallel, elongated, and partially cylindrical lenses) is described in the following U.S. patents: That is, US Pat.
No. 1,254, No. 5,424,533, No. 5,24
No. 1,608, No. 5,455,689, No. 5,27
No. 6,478, No. 5,391, 254, No. 5,42
4,533 and the like. It is also described in U.S. patent application Ser. No. 07 / 931,744, which has been granted a patent. The integral image body provided with the lenticular lens sheet is used by combining vertically divided image pieces. In the case of the three-dimensional integrated image, since the image pieces are aligned with the lenticules, the three-dimensional image can be seen when the lenticules are positioned in a direction perpendicular to the line of sight of the observer. The images may be laminated (ie, glued) to an integral or lenticular lens sheet for convenience. A similar integral image field is described in US Pat.
238 and 3,538,632. Rather than displaying three-dimensional images, they are mainly used to individually display a large number of two-dimensional scenes (such as a plurality of unrelated scenes or a series of scenes representing motion).

Further, US Pat. No. 3,751,258,
Nos. 2,500,511, 2,039,648, 1,918,705 and British Patent 492,18.
No. 6 describes an integrated image in which a reflective layer is provided behind the integrated image to enhance the visibility of the integrated image by reflected light.

[0004]

It is known that different images on an integral image object can be viewed by the observer moving with respect to the image object and viewing the image object at different angles. Further, in U.S. Pat. No. 3,562,941, different images can be viewed from the same position by moving the lenticular image relative to the lenticular lens sheet. However, such a configuration requires a complicated motor mechanism. Further, it is difficult to keep the image aligned with the lens (especially when the image is small). Therefore, the observer can change the observation position, use a method such as changing the arrangement of the image and the lens, or display different images of the integral image body to the observer without holding or tilting the image by the user. It would be desirable to have a relatively simple device. It would further be desirable if such a device could be installed on a fixed surface such as a vertical or horizontal surface.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems. According to one aspect of the invention, there is provided an integral image display assembly having an integral image body supporting at least a first and a second integral image, and a base positioned against a surface. The base has a support that holds the integral image body facing forward. The support allows the image body to swing in a first direction between a first position and a second position, while holding the image body stable in a direction transverse to the first direction. Between the first position and the second position, the first and second images can be viewed from the same front viewpoint position.

In one aspect of the present invention, there is provided an integral image display assembly having an integral image body supporting at least a first and a second lenticular image and a base mountable on a horizontal surface. The base has a support for holding the image body so that the integral image body extends upward and faces forward. The support allows the image body to tilt between a laterally stable front and rear position. Between the front position and the rear position, the first and second images can be viewed from the same front viewpoint position.

[0007] In another aspect of the present invention, there is provided a base of the type described above.

According to the present invention, even if an image is adhered to an integrating lens sheet or a barrier strip sheet,
A relatively simple device is provided that can display different images of the integral image field to a viewer. At this time, the viewer does not need to change the position, and the user of the apparatus does not need to hold or tilt the image. Also, the device of the present invention is convenient because it can be installed or mounted on a fixed surface, such as a vertical or horizontal surface.

[0009]

DETAILED DESCRIPTION OF THE INVENTION In the present invention, the integral image element may be a fly-eye lens sheet or a barrier strip sheet, but is more preferably a lenticular lens sheet having a lenticule on the front surface. . Alternatively, the integrating lens sheet may have an entire region where the refractive index is variable. This region is configured to deflect light rays optically (relative to a curved outer surface, flat outer surface, or other shape) similar to a conventional fly-eye or lenticular lens sheet. . The rear surface of the lens sheet may also be curved to enhance the lens effect, or to compensate for a curved focal plane inherently present in the lens configuration. As a result, the curvature of the rear surface of the lens sheet can be set so as to match the curvature of the focal plane of the lens. Further, an “integral” image refers to an image composed of a group of segments (interlaced lines in the case of a lenticular lens sheet) of at least one completed image (often two or more). Since each segment group is arranged along an individual lens, one or more images can be observed if the line of sight is positioned at an appropriate angle with respect to the image forming body.

The "three-dimensional image" in this specification means an integrated image having a visual depth component when viewed through a lens. The depth component means a property of being able to see at least part of the periphery of an object in a scene, and is obtained by interlacing lines obtained from different perspective views of the same scene by a known method. For example, US Pat. No. 5,278,608 describes the interlacing of lines from different scenes to form suitable lenticular composite images and exposing or writing these images to the back of a composite image body.
No. 5,276,478 and 5,455,6
No. 89. Therefore, a three-dimensional image always includes at least two viewpoint videos (views) of a certain scene. A two-dimensional image refers to an image that has no visual depth component when viewed on a product. However,
A “two-dimensional image” is not one of the views of a three-dimensional image.

Further, the terms indicating directions such as “front (front)”, “upper (upper)”, and “lower (lower)” used in this specification are used only in a relative sense (general). In general, these terms indicate directions relative to commonly used assemblies).

In FIG. 1, the integral image display assembly is designated by the reference numeral 2. The assembly 2 has a lenticular image body 4 as an integral image body. The lenticular image body 4 carries on its front surface a series of mutually parallel lenticules (lenses) 6, each arranged horizontally. Behind this lens, a lenticular image is arranged in a known manner. Integral image field 4
Has at least a first and a second integral image, which can be seen from different angular positions with respect to this image body. Usually, the integral image body 4 has many images, for example, 24 images. These images are two-dimensional images, all or part of which may or may not have common scene elements (such as, for example, an image showing the movement of a scene object). Good. However, the integrated image (a matc
When used with a hing integral image), the image may be three-dimensional. In the figure, the fixed viewpoint position 30
By changing the vertical viewpoint angle 32 between the object and the image body 4, each image can be viewed from this fixed viewpoint position 30 with respect to the assembly 2. The image body 4 is held in an elongated slot 14 provided in a support section 12 (the support section 12 forms the base 10). The support 12 is
Below it has a convex lower surface 16, an elongate stop 18 at the front end and another elongate stop 20 at the rear end.

Next, the operation will be described. The assembly 2 shown in FIG. 1 rests on a horizontal surface 40. The user can manually tilt the support 12 forward or backward from the illustrated stop position at least until the stop 18 or 20 contacts the surface 40. Here, when the user releases the hand, the support unit 12 repeatedly displays different images of the image body 4 while repeatedly swinging forward and backward in the direction of the arrow 33 around the stop position. The shape of the support 12, in particular the convex lower surface 16, serves as a means for causing said repetitive rocking movement. That is, the support portion 12 and the image body 4 are first tilted by hand from the stop position shown in FIG. 1 and then swing repeatedly due to the shape of the convex lower surface 16.

In the embodiment shown in FIG. 2, the assembly 2 comprises an elongate base 10, which includes a support 12a which is two clips attached to a swivel. The base 10 further includes a fixing portion 11 having a rear surface 11a (FIG. 3). The rear face 11a is magnetized or has an adhesive layer, by means of which the fixing part 11 can be glued and fixed to the vertical surface 50 (FIG. 3). FIG. 3 is a side view of the assembly of FIG. In this case, the image body 4 is indicated by an arrow 34
, The image can be viewed in different directions on the image body 4 by rotating in the vertical direction about the support portion 12a.
Alternatively, the assembly of FIG. 2 can be mounted such that FIG. 3 is a top view. In this case, different images on the image body 4 can be viewed by rotating the image body 4 in the direction of arrow 34 in the horizontal direction around the support portion 12a. The pivoting movement can be started by the user from the initial stop position indicated by the solid line in the figure. When the image body 4 rotates in the vertical direction, that is, FIG.
Is a side view, the rotational movement can be maintained for a certain period of time by appropriate balance adjustment of the image body 4. On the other hand, if the image body 4 is rotated in the horizontal direction, the rotation can be maintained by a suitable spring (not shown) or another suitable mechanism. Such a proper balance adjustment,
A spring or other mechanism serves as a means to cause the repetitive pivoting movement described above.

The embodiment shown in FIG. 4 is essentially the same as the embodiment of FIGS. However, in the embodiment of FIG. 4, the support portion includes a flat member 12b in addition to the swivel clip 12c. The image body 4 is attached to the member 12b by a suitable bonding means such as an adhesive. In this case, the center axis of the rotation need not be on or near the image body 4. In addition, this axis may be on the same plane as the planar image body 4, but it is not always necessary. As with the embodiments of FIGS. 2 and 3, FIG. 4 can be a top view or a side view. In the case where FIG. 4 is a view viewed from above, different images of the image body 4 can be seen by rotating the image body 4 in the horizontal direction in the direction of the arrow 36. On the other hand, when FIG.
Is rotated in the vertical direction in the direction of the arrow 36, different images of the image body 4 can be seen. When FIG. 4 is a side view, the surface of the assembly 2 is turned 180 degrees so that the member 12b and the image body 4 do not go upward from the swivel clip 12c as shown in FIG. ,
It can also extend downward. In any case, the repetitive swivel movement can be maintained by a suitable weight, spring, or other mechanism not shown. A weight, spring, or other mechanism serves as a means of causing repetitive rotation after the image body 4 is first manually moved.

Next, the embodiment shown in FIG. 5 is the same as FIGS. 2 and 3. However, the assembly 2 shown in FIG. 5 has a fixed base 13. This base 13 is
It simply rests on a horizontal surface. Image body 4 is arrow 3
By rotating repeatedly about the clip 12c in the direction of 8, different images of the image body 4 can be seen.

In any of the embodiments described above, the repetitive pivoting movement of image body 4 can be initiated or maintained by a suitable motor drive, not shown. This suitable motor drive means serves as a means for causing repetitive rotation after the first manual movement of the image body 4 from the stop position or without such movement. Furthermore, when the image body 4 can be observed by transmitted light, an electroluminescent body can be attached to the base 10 so as to be located behind the image body 4.

The present invention has been described with reference to a preferred embodiment. However, variations and modifications are possible with the prior art within the scope of the invention.
