Abstract:
A process for in-line lenticular film manufacturing having a selected web orientation includes providing an optically clear material web to an in-line converting and/or printing press. The optically clear material web is advanced in the in-line converting and/or printing press in a machine direction of the press. The press includes a lenticule forming means for forming lenticules in the optically clear material web. The lenticules are formed in a selected orientation relative to the machine direction of the press.
Abstract:
A method for creating realistic synchronisation of a sound sample including speech to the motion of a lenticular image is disclosed, together with a device for achieving such synchronisation. The device includes a lenticular image consisting of a number of different individual images spliced together and printed on a substrate which can be moved relative to a lenticular screen to give the appearance of animation that the lenticular image. The sound sample is ideally stored in the memory of a sound chip and the synchronisation is achieved using a processor. In accordance with the invention, the synchronisation is achieved in a realistic and intrinsically simple manner by using a lenticular image which consists only of a few individual images taken from a sequence of a character or person opening and closing its mouth thus resulting in a very short animation sequence and using electronics to repetitively animate the sequence for substantially each and every syllable pronounced in the speech within the sound sample.
Abstract:
An in-line three-dimensional image construction includes an optically clear film having a top surface and a bottom surface. A reverse interlaced image is provided on at least a portion of the bottom surface of the optically clear film. A plurality of lenticules are provided on the top surface of the optically clear film opposite the reverse interlaced image on the bottom surface of the optically clear film, corresponding to the interlaced image. An illusion of a 3D image corresponding to the interlaced image results from viewing the interlaced image through the plurality of lenticules. A method of manufacturing the in-line three-dimensional image construction includes providing an optically clear film having a top surface and a bottom surface, with the film being defined by a lengthwise machine direction reference axis, and by a transverse reference axis that is substantially perpendicular to the lengthwise machine direction reference axis. A reverse interlaced image is printed on the bottom surface of the film, with the image being oriented substantially parallel to the machine direction reference axis, or, alternatively, substantially parallel to the transverse reference axis. A plurality of lenticules are created on the top surface of the film, opposite the reverse interlaced image on the bottom surface, and corresponding to the interlaced image. The lenticules are, respective to the interlaced image, oriented substantially parallel to the machine direction reference axis or, alternatively, substantially parallel to the transverse reference axis.
Abstract:
A set of enhanced apparatuses and a computer integrated processes are provided for creating large scale 3D integral photography images. A large number of mini projectors in a grid on top of each other and beside each other, are exposed individually with a computer calculated reverse (pseudoscopic) perspective image. The curved photo layer inside the projectors obtains sharp high resolution images through the achromatic behavior of the lens system. A guided back light system directs the light from the back through the diaphragm apertures.
Abstract:
In a case of obtaining a line-shaped image through image processing using a computer, an amount of data to be processed is reduced and a final stereoscopic image is formed by using a usual image. A plurality of two-dimensional images having different parallaxes are converted into line-shaped images, with forming a first image from the line-shaped images in view of projection angles of lenticular lenses, a second image is formed by a usual planar image, and a composite image formed by the first image and the second image is formed on a recording medium disposed beneath the lenticular lenses.
Abstract:
The present invention is an optical device having an anisotropic lens array that enables the viewer to perceive a repertoire of preselected images over a first range of angles of regard or to see through the device to a scene beyond the device without distortion. The preselected images in one orientation gives the illusion of a repertoire of images at differing depths. The preselected images at a second orientation can produce a set of optical effects wherein: one image gradually transforms to another; the repertoire of images are unrelated and change suddenly from one to another; the repertoire of images are frames of a motion scene; or, the repertoire of images represent a scene at differing magnifications. Previous attempts at similar objectives have failed to achieve either distortion-free windowing or a reasonably rich repertoire of images. The device may also be applied to applications requiring optical anisotropy such as privacy filtering.
Abstract:
A method for aligning a lenticular sheet, in accordance with the present invention, includes applying curable adhesive to a surface and placing a lenticular sheet over the curable adhesive on the surface. The adhesive is cured at a first end portion of the lenticular sheet such that the first end portion is aligned with a first reference position. A temperature of the lenticular sheet is adjusted to align a second end portion of the lenticular sheet with a second reference position. Remaining portions of adhesive are cured to secure the lenticular sheet.
Abstract:
A three-dimensional image recording/reproduction method, and an apparatus therefor. An opaque light control panel having a large number of fine light transmission portions at predetermined locations is placed between an object and a recording panel, and a large number of small images of the object are formed on the recording panel through the minute light transmission portions. The small images recorded on an picture display panel are reproduced to display the three-dimensional image of the object. An opaque panel having an opening is disposed around the object or between the object and the light control panel, and a conversion operation is carried out so as to reverse the small image of the opening formed on the recording panel point-symmetrically by 180 degrees with respect to a point, at which a line connecting the center of the opening of the opaque panel to each fine light transmission portion, being the point of symmetry. The cubic image is formed in front of the light control panel.

The method comprises; fixing at least one set of differently colored alignment lines onto the substrate for projection through the lenticular lens sheet, positioning the lens sheet over the substrate, viewing at least one set of differently colored alignment lines as projected through the lens sheet, and adjusting the position of the lens sheet relative to the substrate according to a characteristic of the projected image.
Abstract:
A lenticular optical system is described in which a composite image is viewable through a lens sheet from a first angle and an object or image placed at a preselected distance beneath the composite image is viewable from a second angle. Optical designs and alignment processes are disclosed which make possible the economical production of thin materials which facilitate the manufacturing and utilization of the optical system in packaging and the like.
