Definitions

  • the invention relates generally to the field of integral image elements which may disPlay depth, motion or other images, and methods of making such elements.
  • Integral image elements which use a lenticular lens sheet, fly's eye lens sheet, or barrier strip sheet and a three-dimensional integral image aligned with the sheet, so that a user can view the three-dimensional image without any special glasses or other equipment, are known.
  • imaging elements and their construction are described in "Three-Dimensional Imaging Techniques" by Takanori Okoshi, Academic Press, Inc., New York, 1976.
  • Integral image elements having a lenticular lens sheet are also described in the following Unites States patents: US 5,391,254; US 5,424,533; US 5,241,608; US 5,455,689; US 5,276,478; US 5,391,254; US 5,424,533 and others; as well as allowed US patent application Serial Number 07/931,744.
  • Integral image elements with lenticular lens sheets use interlaced vertical image slices which, in the case of a three-dimensional integral image, are aligned with the lenticules so that a three-dimensional image is viewable when the lenticules are vertically oriented with respect to a viewer's eyes.
  • the image may be conveniently laminated (that is, adhered) to an integral or lenticular lens sheet.
  • Similar integral image elements such as described in US 3,268,238 and US 3,538,632, can be used to convey a number of individual two-dimensional scenes (such as unrelated scenes or a sequence of scenes depicting motion) rather than one or more three-dimensional images.
  • Integral image elements using reflective layers behind the integral image to enhance viewing of the integral image by reflected light are also described in US 3,751,258, US 2,500,511, US 2,039,648, US 1,918,705 and GB 492,186.
  • one aspect of the present invention provides an integral image display assembly, comprising:
  • an integral image display assembly comprising:
  • Another aspect of the present invention provides a base of the types described above.
  • the present invention then, provides, a relatively simple device which can display the different images of an integral image element to a viewer even when the image is adhered to the integral lens sheet or barrier strip sheet, without the viewer having to change location, or the user having to hold and tilt the image.
  • Devices of the present invention can conveniently rest or be mounted on a fixed surface, such as a vertical or horizontal surface.
  • the integral image element could use a fly's eye lens sheet or a barrier strip sheet, it is more preferably a lenticular lens sheet with lenticules on a front surface.
  • the integral lens sheet could have regions of varying indices of refraction through its volume configured in such a way as to provide (in conjunction with the surfaces of the sheet, such as a curved external surface, flat external surface or some other shape) the same optical deflection of light rays as would be provided by a conventional fly's eye or lenticular lens sheet.
  • the back surface of the lens sheet may also be curved so as to either strengthen the lens effect or compensate for the curved focal plane which may be inherent in the lens construction.
  • the curvature on the back side may be of such a shape as to match the curvature of the focal plane of the lens.
  • an "integral" image is referenced an image composed of segments (interlaced lines, in the case of a lenticular image) from at least one complete image (and often more than one image), which segments are aligned with respective individual lenses so that each of the one or more images is viewable when a user's eyes are at the correct angle relative to the imaging element.
  • a three-dimensional image is meant an integral image which, when viewed through the lens, has a visible depth element.
  • a depth element means the ability to at least partially look around an object in the scene. This can be obtained by interlacing lines from different perspective views of the same scene.
  • suitable lenticular composite images by interlacing lines from different scenes, and their exposing or writing to the back side of integral imaging elements is described for example, in US 5,278,608, US 5,276,478 and US 5,455,689.
  • a three-dimensional image necessarily includes at least two views of a scene.
  • a two-dimensional image is referenced an image which, when viewed in the product, does not have any viewable depth element.
  • a "two-dimensional image” though, is not one of the views of a three-dimensional image.
  • FIG. 1 an integral image display assembly is generally designated by numeral 2.
  • Assembly 2 has integral image element in the form of a lenticular image element 4, a front surface of which carries a series of horizontally oriented parallel lenticules 6. Behind lenticules 6 is positioned a lenticular image, in a well known manner.
  • Element 4 will have at least first and second integral images viewable from different angular positions with respect to the element. Typically, element 4 will have many images, for example 24 images. These images will be two-dimensional images and some or all could contain common scene elements (such as in images illustrating motion of some scene object), or some or all of the images may have no elements in common.
  • each of such images can be viewed from a fixed viewing position 30 relative to assembly 2 when the vertical viewing angle 32 between the position 30 and element 4 is altered.
  • Element 4 is retained in an elongated slot 14 in a support 12 (which support 12 defines base 10).
  • Support 12 has a convex lower surface 16 as well as an elongated stop 18 at a front end, and another elongated stop 20 at a back end.
  • assembly 2 of FIG. 1 is placed on a horizontal surface 40 and a user can manually tilt support 12 forward or backward from a rest position shown in FIG. 1 at least until stop 18 or 20, respectively, encounters surface 40.
  • support 12 will repetitively pivot backward and forward in direction of arrow 33 about the rest position and repetitively displaying the different images on element 4.
  • the shape of support 12 (particularly the convex lower surface 14) acts as a means for causing the foregoing repetitive pivotting after the initial manual tilting from a rest position of support 12 and element 4 shown in FIG. 1.
  • FIG. 2 the embodiment of the assembly 2 shown therein, has an elongated base 10 which includes a support 12a in the form of two clips on a swivel.
  • Base 10 also includes a fixed section 11 which has a back surface 11a which is either magnetized or has an adhesive layer. Magnetized or adhesive back surface 11a allows section 11 to be stable attached to a vertical surface 50.
  • FIG. 3 is a view from the side, then the different images on element 4 can be viewed as element 4 pivots in the direction of arrow 34 about support 12a in the vertical direction.
  • assembly 2 could be mounted so that FIG.
  • FIG. 3 is a top view, in which case the different images on element 4 can be viewed as element 4 pivots in the direction of arrow 34 about support 12a in the horizontal direction.
  • the pivoting motion can be started manually from a rest position (shown in solid lines in the Figures) and, if element 4 is pivoting vertically (that is, FIG. 3 is a side view) could be sustained for a time by proper balancing of element 4.
  • element 4 is pivoting horizontally, on the other hand, the motion could be sustained by suitable springs (not shown) or some other suitable mechanism.
  • the suitable balancing, springs, or some other mechanism would as a means for causing the repetitive pivotting.
  • FIG. 4 is essentially the same as that of FIGS. 2 and 3.
  • the support includes both a flat member 12b as well as swiveling clips 12c.
  • Element 4 is positioned on member 12b by any suitable attachment means (such as adhesive). It will be seen in this case that the axis about which pivoting occurs need not be on or adjacent to element 4. While that axis may be co-planar with planar element 4, this is not essential.
  • FIG. 2 and 3 FIG.
  • FIG. 4 can either be a view from the top (in which case the different images on element 4 are viewed as it pivots horizontally in the direction of arrow 36), or a view from a side (in which case the different images on element 4 are viewed as it pivots vertically in the direction of arrow 36). It should also be noted that if FIG. 4 is considered a side view, assembly 2 could be inverted 180 degrees on surface so that member 12 b and element 4 would be extending downwardly from swiveling clips 12c (rather than upwardly as viewed in FIG. 4). In either event, the reciprocating swiveling motion could be maintained by suitable counterweights, springs, or other mechanism (not shown; which would act as a means for causing the repetitive pivotting after an initial manual displacement of element 4).
  • FIG. 5 this embodiment is similar to that of FIGS. 2 and 3.
  • the assembly 2 in FIG. 5 is provided with a fixed base 13 which is intended to simply rest on a horizontal surface.
  • the various images on element 4 will be observed as it reciprocally pivots about clips 12c in the direction of arrow 38.
  • the reciprocating pivoting motion of element 4 can be initiated and/or sustained by means of a suitable motor drive (not shown; which would act as a means for causing the repetitive pivotting with or without an initial manual displacement of element 4 from a rest position).
  • a suitable motor drive not shown; which would act as a means for causing the repetitive pivotting with or without an initial manual displacement of element 4 from a rest position.
  • an electric light could be attached to base 10 so as to be behind element 4 (when element 4 can be viewed by transmitted light).
