Abstract: PROBLEM TO BE SOLVED: To prevent a mixture of movement and depth expression elements and to provide a stereogram for making the effects of movement and depth expressions compatible by synthesizing an original picture film with reduced movement expression pictures and that of depth expression pictures larger in the number of constituting elements than the reduced movement expression pictures for forming an original picture. SOLUTION: The original picture films having the depth and movement expression pictures by photographing is used. The original picture for the stereogram includes the depth expression pictures in the same number as frames, as the number of the constituting elements. But the movement expression pictures as the constituting elements are thinned and only representative frames are selected and superimposed on the depth expression pictures, to obtain composite pictures. The peculiar patterns of the finger patterns of the movement expression pictures, for instance a rock pattern 2b, a scissors pattern 2c and a paper pattern 2d are selected as representative pictures and the patterns 2b, 2c and 2d are arranged in three frames of a background 1a included in the depth expression picture and three frames next to the patterns 2c and three frames next to the patterns 2d, respectively.

Abstract: PURPOSE: To provide a holographic stereogram with which the manhours for treatment are reduced by effectively decreasing the number of frames of parallax images handled at the time of forming an original picture and at the time of composition, and the degradation in the image quality is prevented by complementing the parallax shape of a subject with three colors and its production. CONSTITUTION: The original pictures are successively arranged with the three frames of a camera as one set, for example, red is allotted to the first frame, green is allotted to the next second frame by shifting the frame by a 1/3 pitch and blue is allotted to the remaining third frame by shifting the frame by a 1/3 pitch. Next, the red is allotted again to the fourth frame and the master hologram 10 of colors is formed by repeating the similar allotment. Thereby, the master hologram 10 of the parallax images complementing the parallax shape of the subject among the three colors is formed. The Lippman hologram or rainbow hologram is formed by using such master hologram, thereby, the holographic stereogram of a white color reproduction type is produced.

Abstract: PURPOSE: To make it possible to produce different diffraction grating patterns in superposition on each other or these diffraction gratings and hologram images in superposition on the same substrate by specifying the treatment of the overlapped parts of dot arrangement. CONSTITUTION: The one dot shape of the overlapped parts is actually patterned to an intrinsic shape and the other dot shape to a shape lacking the overlapping parts in the case the dot arrangement of the desired pattern is superposed. If, for example, the two-dimensional images 1 by raster data and the function curves 2 by vector data are superposed on each other, the dots constituting the function curves 2 are formed to the intrinsic shape and the dots constituting the two-dimensional images are formed to the shape lacking the overlapping parts by giving priority to the function curves 2 over the two-dimensional images 1 in order to stress the function curves 2. The dot relations are formed to such shapes that the one is a perfect shape and the other is a sacrificial shape as shown by a partially enlarged Fig. The diffraction grating patterns which are intricate, are highly accurate and have a high effect of preventing forgery are obtd.

Abstract: PURPOSE:To provide a diffraction grating pattern by two-beam interference method and its production method by which the outline of the pattern as a whole to be produced can be accurately realized without depending on the dot shape. CONSTITUTION:The exposure area on a photosensitive material is regulated by using a mask having a specified aperture according to the outline of the pattern to be produced. By this method, such a diffraction grating pattern is produced that the outline of dots is in an arbitrary form depending on the pattern (the shape of the aperture in the mask) can be produced.

Abstract: PURPOSE:To generate an intermediate color by placing the photographed area of a subject in an overlap state on respective master holograms. CONSTITUTION:Pieces of information recorded on the master holograms 220, 222, and 224 are projected on a dry plate 360 where a rainbow hologram 362 is formed as light wave surfaces 370, 372, and 374 passed through slits 352, 354, and 356 respectively. The dry plate 360 is irradiated with reference light 342, which interfere with the light wave surfaces 370, 372, and 374 to form the rainbow hologram 362. Pieces of light information corresponding to masks 120, 124, and 128 are recorded on the dry plate 360 as a red, a green, and a blue image. The bits of information corresponding to the masks 122, 126, and 130 are mixed to generate yellow as the complementary color of blue, magenta as the complementary color of green, and cyan as the complementary color of red.

Abstract: PROBLEM TO BE SOLVED: To enhance a deterrent effect with respect to the unauthorized duplication of an optical disk by judging disk authenticity based on the diffraction grating pattern arranged concentrically around the center of the optical disk outside a data recording area. SOLUTION: Diffraction grating pattern 10 is provided by being arranged concentrically in a ring band shaped area between circles 4, 5 having the same center point inside a read-in area 3. After recorded information are read out by an optical pickup and also only one side of ±1st order diffracted light beams from the diffraction grating pattern is received by a light receiving element which is fixed by being designed and arranged so that unwanted diffracted light beams do not exert adverse influence on them and the received signal is converted into an analog signal, the signal is binarized to be a digital signal. Then, the judgment of the authenticity is performed by comparing the digital signal information with the reference information provided in the own body of a reader and when the digital information do not coincide with the reference information, access to recorded information is refused by the program stored in the reader. When a protect and a password are combined as the reference information, the security can be more enhanced.

Abstract: PROBLEM TO BE SOLVED: To easily confirm the justice of a hologram only by superposing a translucent sheet having diffusibility on the hologram, and observing the hologram through the sheet, by intentionally forming a pattern (concealed information) in such manner that an area where dots or cells do not exist, can not be visually judged, and mixing the same in the diffraction grating pattern. SOLUTION: A pattern is intentionally formed in such manner that an area where dots or cells do not exist, can not be visually judged, and is mixed in a diffraction grating pattern. Only the pattern corresponding to the layout of fine dots or cells, can be visualized, when the diffraction grating pattern is observed through the white light (a), and the concealed information formed by the area not having dots or cells (black area in the drawing), can not be recognized. When the diffraction grating pattern is observed through a translucent sheet having the diffusibility, and superposed to the surface of the diffraction grating pattern (b), the concealed information 'E' formed by the area not having dots or cells, can be judged.
