Abstract:
A lenticular image printer creates an image on received media having a series of lenticules with parallel axes. The printer includes a transport system adapted to move received media in an in-track direction substantially perpendicular to the axes of the lenticules. An alignment beam generator is arranged to transmit an alignment beam through the lenticules of received media such that the alignment beam is in-track position-modulated by the lenticules. Three position-sensing detectors are aligned in a cross-track direction perpendicular to the in-track direction so as to receive the position-modulated alignment beam whereby the position of the position-modulated alignment beam on the detectors provides an indication of the relative alignment of the axes of the lenticules and the cross-track direction.
Abstract:
A method for remote approval of lenticular images and an apparatus which can execute the method. In the method, a centralized hub station receives a series of images. A user then views at a terminal remote from the centralized hub station, a simulated lenticular image using at least some images of the series displayed to simulate viewing an actual lenticular image formed from the images of the series. Following such viewing, an approval is transmitted from the remote terminal to the centralized hub station, for a plurality of the images of the series to be printed as the actual lenticular image. The actual lenticular image is then printed at the hub station based on the approval.
Abstract:
A 3D printer comprises a scanning laser system. A donor sheet is located in the focal plane of the optical system and carries a thermally transferable colourant such as a dye or pigment. A lenticular screen has a colourant receiving layer which receives colourant from the donor sheet to form 3D pixels, each comprising interlaced 2D pixels, aligned with lenticules of the screen. A detector array responds to laser light which has been transmitted through the lenticular screen, and a print register control system uses the detector output correctly to position the scanning laser beam to compensate for irregularities in the lenticular screen.
Abstract:
A printer device for lenticular photographic images easily transforms electronic image files into photographic hard copy. The printer device includes a cathode ray tube screen and a projection lens. A filter wheel may be used for inserting optical filters into the optical path of the projection lens. A lenticular photographic print assemblage is aligned and affixed at the focal plane of the projection lens. The lens and the image on the cathode ray tube screen are then moved in differential amounts in the direction parallel to the plane of the aligning and affixing process, and normal to the axis of the lenticules on the lenticular photographic print assemblage. Finally, an electronic video display driver and computer coordinate the motions with changes of the images displayed on the cathode ray tube to allow the correct exposures of color and angular perspective views inherent in the image files onto the photographic emulsion coating of the lenticular photographic print assemblage, for the subsequent developing and autostereoscopic viewing.
Abstract:
A system and method that captures depth images of different content documents or scenes to be provided in a compound document. The viewpoints for the captured depth images are used to adjust the positioning of the images on a planar image recording substrate, so that different content depth or three-dimensional images will be viewed from different angles of the single document when the substrate is viewed through a depth image display device. The images are printed on the planar substrate and the screen is attached producing the desired compound document.
Abstract:
The invention provides a lenticular lens type three-dimensional image display device and a method of fabricating the device without a need for a clear plastic substrate transposed between the image and lenticular lenses. The device can be obtained by directly printing curable coatings onto the image, making them particularly well suited for volume production. The combination the image printing and application of curable coatings process can be joined together to conduct the single pass-process. The single pass-process allows for flexibility of the printing only selective areas of the substrate. Moreover, this process allows the device to be recyclable.

The method comprises printing an interlaced composite image according to a reference grid of a printer, providing a lenticular lens sheet having a plurality of parallel lenticular lines between a plurality of lenslets, selecting an acute angle for an intersection between the first and second axes according to a function of a resolution of the interlaced composite image and a pitch of the lenticular lens sheet, and positioning the lenticular lens sheet so that the intersection forms the acute angle.
Abstract:
A group recording method for an electronic device is provided. The method includes establishing a connection between the electronic device and at least one other electronic device through wireless communication, acquiring a first image created by photographing a target subject, acquiring a second image created by photographing the target subject from the another electronic device, and concurrently recording by the electronic device the first image and the second image and displaying the first image and the second image together on a display screen, in which a second viewpoint corresponding to the second image is different from a first viewpoint corresponding to the first image.
Abstract:
A method for screening color separations of a lenticular image having a lenticular frequency of lenticular lenses for viewing the image, with a lens width l. An amplitude-modulated halftone image is calculated for each color separation at one screen angle with a rational number tangent and screen frequency. The screen has non-orthogonal screen cells spanned by vectors u, v for a specific color separation. A distance k is defined. Directions of vectors u, v relating to perpendicular direction relative to image strips of the lenticular image are defined for the specific color separation. First (n, m) and second (i, j) pairs of rational numbers are defined, to satisfy a system of equations: n*ux+m*vx=0, n*uy+m*vy=1, i*ux−j*vx=k and i*uy−j*vy=0 for vectors u=(ux, uy) and v=(vx, vy) spanning screen cells. A computer program product is also provided.
Abstract:
A method for searching a printing frequency to display a 3D picture includes breaking an image into strips and using NumLen lenses to form a NumLen-1 image cycle. After the NumLen-1 image cycle is formed, a quantity of images of the image cycle is defined to be dpi/lpi, where dpi is dot per inch of a printer and Ipi is lens per inch of a lenticular lens. Therefore, a quantity of the image per inch is arrived.
