  • Patent number: 11004174
    Abstract: A variable image display body and a lenticular image formation method that are capable of displaying a variable image without incongruity are provided. In a variable image display body, lenticular images are composed of arranged image strips obtained by scaling a plurality of images so that subject images appearing in the respective images have the same size, subjecting the scaled images to position adjustment so that reference portions of the subject images in the scaled images are located at the same position, in the superimposed state, trimming a region in which a predetermined number of the scaled images are overlapped and the subject images are included, and extracting image strips in the form of lines from each of the trimmed images.

  • Patent number: 9007691
    Abstract: An object is to provide an image display sheet capable of realizing a smooth pseudo moving image and observing the image with reduced in discomfort. A configuration is provided in which a lenticular sheet composed of an arrangement of a plurality of cylindrical lenses 1a and an image forming layer 3 are laminated, and the image display sheet is formed capable of observing an image formed on the image forming layer 3 from the convex shape side of the cylindrical lenses 1a of the lenticular sheet, as a virtual image with movement, or movement and deformation. The image forming layer 3 is formed repeatedly with a plurality of images 3 for displaying virtual images in association with the cylindrical lenses 1a so as to correspond to the cylindrical lenses 1a, respectively, one-on-one, and difference between an arrangement pitch length A of the cylindrical lenses 1a and a pitch length B of the repeatedly formed images 3a formed on the image forming layer 3 is in a range of 0% to 10%.

  • Publication number: 20130154907
    Abstract: An image display device includes an aggregate of convex lenses arranged on a surface thereof with a predetermined lens pitch Px in at least one direction Dx (in which x is a suffix representing the direction); and a display unit displaying a plurality of element images on a focus surface of the convex lenses or near the focal plane surface in a manner aligned along the surface to thereby display the element images aligned in the direction Dx with an image pitch wx different from the pitch Px. By using the image display device, a moiré stripe formed by shift in pitches between a plurality of convex lenses and a plurality of element images is stereoscopically displayed as an image or displayed as an image of animation, and the element images are composed of an aggregation of a plurality of parallax or frame component images.

  • Patent number: 7776402
    Abstract: The present invention relates to a method for pattern formation and an apparatus for pattern formation, the method comprising: applying, between partition lines for pattern formation formed on a surface of a base member, a resin composition for pattern formation having small compatibility or substantially no compatibility with a resin forming the partition lines for pattern formation, in a state in which the surface of the base member with the partition lines for pattern formation formed whereon is placed face down; maintaining the state in which the resin composition for pattern formation is held on the surface of the base member that is placed face down in order to form the resin composition for pattern formation applied between the partition lines for pattern formation into a downward convex shape; and curing the resin composition for pattern formation that is formed into the downward convex shape in order to form a pattern.

  • Patent number: 5800907
    Abstract: A lens body or article with lens is produced by forming lens-forming defining lines on the surface of a substrate, coating a lens-forming resin on the surface to thereby allow the lens-forming resin to swell in a convex form between the lens-forming defining lines by means of the repellency of the lens-forming resin with the lens-forming defining lines, and then curing the lens-forming resin. To this method is added a step of providing an image on the substrate to obtain an article with lens having the image. The image can stereoscopically be seen through the article with lens obtained by this method.
