Abstract: Conventional moire image-producing patterns have often been produced manually by trial and error, and many steps have been required to produce a moire image having good appearance. According to the present invention, a feature value such as a grayscale value is extracted from a design pattern on which a moire image is based. Then, an aperture/non-aperture ratio of a moire pattern is set according to the feature value, taking into account the specification of layers desired for a moire image, setting of a basic pattern, and information regarding a moire display. In addition to the aperture/non-aperture ratio, a phase shift amount and a pitch ratio can be further added to efficiently produce a moire image having a beautiful appearance and excellent design. Moreover, such a method for generating a moire pattern can be incorporated in a system to further improve production efficiency.

Abstract: An image display device includes image cells arranged two-dimensionally. Each image cell has a hologram layer. The hologram layer includes a diffraction grating in which a one-dimensional grating pattern extending in a first direction is repeated in a second direction perpendicular to the first direction. Among the plurality of image cells, two or more image cells that are in a row in the second direction and correlated to one color constitute one image cell group. The image cell group includes a section in which the spatial frequency of the diffraction grating is proportionately small as the distance in the second direction from one end of the image cell group increases such that, while a viewpoint is positioned at a predetermined angle relative to an image display device, the two or more image cells constituting the image cell group display the same color as each other.

Abstract: An optical display body (1) is provided with: a stripe mask (10) that includes a transmission part (T) and a reflection part (R) that is wider than the transmission part, a transmission part and a reflection part which are alternately arranged so as to form a stripe pattern; and a printed body (20) that includes a flattened design (21A) which is a visible image (21B) flattened in a Y direction and which is printed two or more times repeatedly in an X direction. The stripe mask, upon being superimposed on the printed body such that a stripe direction of the stripe mask will be coincident with the X direction of the printed body, allows a visible image to be displayed through the stripe mask.

Abstract: A display member includes: a surface which is an observation object; a first image pattern which is covered by the surface and displays, through the surface, a first image including one or more first information elements for identifying an owner of the display member; a second image pattern which is covered by the surface and in which one or more second information elements are embedded, a part of the second image pattern restricting identification of the one or more second information elements, the second image pattern including a second image that differs from the first image and is for identifying the owner of the display member; and a concealment pattern that is located between the second image pattern and the surface and removes the restriction on identification of the one or more second information elements by concealing the part of the second image pattern.
