Description

Technical Field

[0001] The present invention relates to a hologram used in the field of security printed matter such as banknotes, passports, securities, identity certificates, cards, tickets, etc., which require anti-counterfeiting effects, and is a hologram having a video effect capable of imparting variable information on demand and a method for producing the same.

Background Art

[0002] A video effect in which an image appears to move has high eye-catching properties and is difficult to counterfeit. Therefore, in recent years, it has been increasingly used as an element for discriminating the authenticity of security printed matter. A typical technology having such an effect is a hologram, which is also attached to security printed matter such as banknotes and passports that require the highest level of security and is widely used.

[0003] In the initial hologram, the original plate was produced by an analog photographing method in which object light from an object and reference light were burned onto a dry plate in the form of interference fringes. Currently, by drawing a diffraction grating with an electron beam, a more detailed image representation has become possible. The applicant has filed a technology related to a hologram that realizes an excellent video effect using the electron beam drawing apparatus and a special line drawing configuration different from the conventional one (see, for example, Patent Document 1).

[0004] In addition, in the field of printing machines, printing machines have evolved, and variable information printing using digital printing machines is developing. Variable information printing is a printing method in which different information (variable information) is printed on each medium by creating plate surface data on a printing machine without going through the plate making work of creating a plate surface due to the evolution of the printing machine. For example, like an ID card, it is possible to print individual information such as a face, name, address, phone number, personal number, etc. for each printed matter owned by an individual according to the owner, and it is possible to personalize the printed matter according to the owner.

[0005] Even in the field of holograms, there have conventionally been many technologies aimed at imparting variable information. As one of such methods, there is a technology in which data is written in a post-process to a hologram prepared in advance by irradiating a metal foil or a metal film of a hologram with a laser to remove (demetalize) the metal foil or the metal film (see, for example, Patent Document 2, Patent Document 3, and Patent Document 4).

Summary of the Invention

Problems to be Solved by the Invention

[0007] For example, the technology of Patent Document 1 expresses a moving image effect by sampling a pattern that is compressed or compression-divided by lines or dots composed of an aggregate of arc-shaped diffraction gratings, and an excellent moving image effect is expressed in the reproduced image.

[0008] However, the image having the moving image effect reproduced here is composed of diffraction gratings imparted by an electron beam lithography apparatus, and since it is impossible to instantaneously form the diffraction gratings, it is impossible to impart a different image to each hologram, and there has been a problem that it is difficult to impart variable information.

[0009] In addition, the technologies described in Patent Documents 2 to 4 can apply variable information, which is different for each hologram, as performed by a digital printing machine, by using drawing that imparts information by laser irradiation in a subsequent process to a hologram prepared in advance.

[0010] However, the information imparted by the above-described method simply visualizes and allows easy viewing of regions with different reflectivities formed by removing a part of a metal foil or a metal film. That is, the image imparted to the hologram by a laser does not have the visual effects peculiar to a hologram in which the image changes to another image or moves, and is limited to a simple appearance in which the image imparted by the laser can be simply seen against a background of a highly reflective metal foil or a colorful diffraction grating.

[0011] The present invention aims to solve the above problems, and provides a hologram and a method for producing the same in which information can be imparted by laser irradiation in a subsequent process to a base hologram prepared in advance, and which can impart a so-called moving image visual effect in which an image appears to move, and further provides a hologram capable of instantaneously imparting variable information on demand.

Means for Solving the Problems

[0012] The present invention is a glittering moving image pattern forming body comprising a combination of a group of glittering elements in which a metal film is formed on a hologram forming layer on which a diffraction grating is formed, and a group of variable images having optical characteristics different from those of the metal film, The group of glittering elements is formed by arranging a plurality of glittering elements each comprising a plurality of diffraction gratings formed by at least either a straight line or a curve with a predetermined regularity, The glittering element has a structure in which at least one of the arrangement angle of the diffraction grating or the density of the diffraction grating continuously changes, so that a region that reflects light in the glittering element continuously moves in response to a change in the angle of incident light. The group of variable images has a group of latent image elements in which no metal film exists or a plurality of latent image elements having a lower reflectivity than the metal film are arranged regularly. The latent image element group and the luminescent element group are combined by the same regularity or different regularities, Under regular reflection light, dynamic information due to the interference of the diffracted light of the luminescent element group and the latent image element group appears, and by changing the observation angle, the position of the dynamic information changes and is visually recognized, which is a luminescent moving image pattern forming body.

[0013] In the present invention, the latent image element group is formed by arranging a plurality of latent image elements having at least one of the arrangement pitch, arrangement direction, or angle different from that of the luminescent elements, or 2) arranging a plurality of latent image elements with a compressed base image having at least one of the arrangement direction or arrangement pitch different from that of the luminescent elements, or 3) arranging a plurality of latent image elements with a divided and compressed base image having the same regularity as that of the luminescent elements, which is a luminescent moving image pattern forming body.

[0014] In the present invention, the variable image group further has unique information, which is a luminescent moving image pattern forming body.

[0015] The present invention is composed of a plurality of diffraction gratings formed by at least one of a straight line or a curve, and the luminescent elements having a structure in which at least one of the arrangement angle of the diffraction gratings or the density of the diffraction gratings continuously changes have a predetermined regularity. A method for producing a luminescent moving image pattern forming body, which comprises a combination of a luminescent element group formed with a metal film on a hologram forming layer on which a diffraction grating is formed and a variable image group having at least a latent image element group in which no metal film exists or the reflectivity is lower than that of the metal film and is formed by the same regularity or different regularities as the luminescent element group, A step of setting the regularity of the luminescent elements composed of the diffraction gratings of the luminescent element group, a step of creating variable image group data by creating latent image element group data serving as a basis for the latent image element group using an image processing device, and using the created variable image group data to remove or destroy the metal film of the luminescent element group by laser irradiation to form a variable image group, and a method for producing a luminescent moving image pattern forming body having a step of combining the luminescent element group and the variable image group.

[0016] The present invention is a method for producing a phosphorescent moving image pattern in which a variable image group further has unique information, and includes a step of creating unique information data serving as a basis for the unique information by an image processing device, and synthesizing the unique information data and latent image element group data to create variable image group data.

Effects of the Invention

[0017] Since the phosphorescent moving image pattern of the present invention can form variable information by irradiating a group of phosphorescent elements with a laser or the like and partially removing the metal film of the group of phosphorescent elements, it does not require a layout like printing, and a phosphorescent moving image pattern with variable information can be obtained.

[0018] In addition, since the phosphorescent moving image pattern of the present invention is an image formed by a laser and is a group of latent image elements subjected to special processing in accordance with the regularity of the group of phosphorescent elements, the image appears to move according to the viewing angle, resulting in a moving visual effect. By imparting a moving effect to the variable information itself and forming an image with a moving effect imparted to the variable information adjacent thereto, it is difficult to imitate the moving effect of the present invention as compared with a hologram that simply displays conventional variable information, and therefore the anti-counterfeiting effect is high.

Modes for Carrying Out the Invention

[0020] Modes for carrying out the present invention will be described with reference to the drawings. However, the present invention is not limited to the modes for carrying out described below, and includes various other modes within the scope of the technical idea described in the claims.

[0021] In this specification, the configuration of the hologram forming layer (9) and the metal film (10), which are the main components of the glittering moving image pattern (1), composed of the glittering element group (4) and the latent image element group (6), will be specifically described. In this specification, the glittering moving image pattern (1) refers to a structure including the hologram forming layer (9) and the metal film (10). By providing a transparent layer to the hologram forming layer (9) or providing an adhesive layer (20) for pasting or the like, it becomes a practical form, but these are within the scope of common sense applications of the present invention. Needless to say, this glittering moving image pattern (1) may be pasted on a printed matter having an underlying print such as paper, plastic, or metal.

[0022] In this specification, first, a linear glittering moving image pattern (1) using Moire Magnification (hereinafter referred to as the "Moire magnification phenomenon") will be described in the first embodiment, and then a dot-like glittering moving image pattern (1) also using the Moire magnification phenomenon will be described in the second embodiment. Subsequently, in the third embodiment, a linear glittering moving image pattern (1) using the line configuration of the Integral Photography method (hereinafter referred to as the "IP image method") will be described, and further, in the fourth embodiment, a dot-like glittering moving image pattern (1) using the line configuration of the IP image method will be described.

[0023] Note that the term "linear (line)" as used in this specification refers to a state in which the constituent elements of an image are continuously arranged at a certain distance in a specific direction, and specifically includes dotted lines, broken lines, straight lines, curves, broken lines, etc. On the other hand, the term "dot (pixel)-like" refers to a state in which the constituent elements of an image are grouped together without a specific direction, and specifically includes various figures such as circles, triangles, polygons including quadrilaterals, stars, etc., as well as characters, symbols, numbers, marks, etc.

[0024] (First Embodiment) First, FIG. 1 shows the glittering moving image pattern (1) in the present invention. In this first embodiment, a configuration will be described in which a glittering element (7) configured in a linear form of a straight line to be described later is used to produce Moire having a moving image effect.

[0025] The glittering moving image pattern (1) generally has a structure mainly composed of a diffraction grating (8), which is generally called a hologram, an OVD (Optically Variable Device), or an optical change element. The diffraction grating (8) will be described later.

[0026] In this first embodiment, when viewed by changing the angle of the light incident on the glittering moving image pattern (1), it is the simplest form consisting of a combination of the unique information (2) and the dynamic information (3). By adjacently arranging these two pieces of information without gaps, the anti-counterfeiting property of the unique information (2) is strengthened by the dynamic information (3), and this is an example of enhancing the forgery resistance of the entire glittering moving image pattern (1).

[0027] As an example, the glittering moving image pattern (1) shown in FIG. 2 consists of a combination of a glittering element group (4) and a variable image group (5). Further, the variable image group (5) has a latent image element group (6) that serves as a basis for the vertical interference fringes (moire pattern) of the background, which are the unique information (2) indicating the face image of the holder and the personal number of the holder and the dynamic information (3).

[0028] First, the glittering element group (4) will be described with reference to FIG. 3. The glittering element group (4) in this first embodiment is formed by regularly arranging linear (lined) glittering elements (7) at a first pitch (P1) in a predetermined direction (in this first embodiment, the first direction (S1 direction)). The glittering element (7) is composed of a diffraction grating (8) formed by a collection of minute optical elements with high reflectivity. Note that the "predetermined direction" in the present invention refers to a regular direction appropriately set when arranging each element, such as the first direction (S1 direction) in this first embodiment and the second direction (S2 direction) in the second embodiment described later. Also, the configuration of the diffraction grating (8) will be described later.

[0029] As used herein, "disposed regularly" means that, for the elements to be disposed, in addition to the disposition pitch (P1) and the disposition direction (direction S1), a specific rule is applied to the angle of the elements (vertical in this first embodiment) for disposition. As shown in the cross-sectional view of the group of luminescent elements (4), a highly reflective metal film (10) is provided on a hologram-forming layer (9) in which a diffraction grating (8) is engraved in resin or the like.

[0030] Note that, nominally, it is referred to as the metal film (10), but as long as it has optical properties different from those of the underlying hologram-forming layer (9) and is composed of a film that absorbs light with a wavelength of 1.5 μm or less, it does not necessarily have to be provided by a metal film (evaporation).

[0031] Among the luminescent elements (7), a diffraction grating (8), which is a minute optical element with high reflectivity, needs to be provided, but there are also optical properties that the luminescent elements (7) themselves must satisfy. As shown in FIG. 4, when the angle of the light incident on the luminescent element (7) changes, the positions of the regions (A-1, A-2, A-3) that emit particularly strong diffracted light (under normal reflection light) in the luminescent element (7) must continuously change in accordance with the continuous change in the angle of the incident light.

[0032] The above-described properties are complete essential requirements for the luminescent element (7). When light is incident from a specific direction, a structure in which the entire luminescent element (7) simply emits diffracted light does not satisfy the essential conditions of the luminescent element (7) of the present invention. Further, if the positions of the regions that emit strong diffracted light change discontinuously, that is, discontinuously change, the essential conditions of the luminescent element (7) of the present invention are not satisfied either.

[0033] In order to satisfy the above optical characteristics, the shape of the diffraction grating (8) in the luminescent element (7) is important. FIGS. 5(a) to (d) and FIGS. 6(a) to (d) show examples of the shape of the diffraction grating (8) for satisfying the above-described optical characteristics. The luminescent element (7) in FIG. 5(a) has a diffraction grating (8) formed in an arc shape by a continuous curve, and the luminescent element (7) in FIG. 5(b) is also in an arc shape, but for each of a plurality of cells (7a) obtained by vertically dividing the luminescent element (7), it is a diffraction grating (8) in which a curve is pseudo-formed by a set of straight lines with slightly different angles. The luminescent element (7) in FIG. 5(c) has a diffraction grating (8) in which a set of straight lines with slightly different angles is configured in a shape close to a concentrated line for each of a plurality of cells (7a) obtained by horizontally dividing the luminescent element (7), and the luminescent element (7) in FIG. 5(d) has a diffraction grating (8) composed of a set of diffraction gratings (8) of curves and arcs for each of a plurality of cells (7a) obtained by horizontally dividing the luminescent element (7).

[0034] Also, FIG. 6 shows that the necessary optical characteristics of the luminescent element (7) are provided by changing the density of the diffraction grating (8) instead of changing the angle of the diffraction grating (8). The luminescent element (7) in FIG. 6(a) has a configuration in which the density of the diffraction grating (8) continuously changes from dense to sparse, and the luminescent element (7) in FIG. 6(b) has a discontinuous density change for each cell (7a), and as a whole, the density of the diffraction grating (8) changes from dense to sparse as in FIG. 6(a). The luminescent element (7) in FIG. 6(c) has a discontinuous density change for each cell (7a) as in the structure of FIG. 6(b), but is formed at an angle orthogonal to the diffraction grating (8) in FIG. 6(b), and FIG. 6(d) has a configuration formed at an angle of 45 degrees for each cell (7a). In the configurations of FIGS. 6(b), (c), and (d), although the angles at which light is strongly diffracted are different, they satisfy the characteristic that the positions of regions (A-1, A-2, A-3) in the luminescent element (7) where light is particularly strongly reflected change.

[0035] Next, the variable image group (5) will be described. In this specification, the variable image group (5) has a latent image element group (6) that serves as the basis of the moiré pattern, which is the unique information (2) and the dynamic information (3). In this specification, the unique information (2) refers to personal information such as the face image of the holder and the personal number shown thereon. This is so-called variable information, and since it is an image that varies for each holder, it becomes an effective form for preventing forgery and counterfeiting.

[0036] Next, regarding the latent image element group (6) that serves as the basis of the moiré pattern, which is one of the dynamic information (3), it will be specifically described with reference to FIG. 7. In the case where the latent image element group (6) is combined with the unique information (2) that is simultaneously provided during production to form the variable image group (5), in order to prevent the visible image from becoming unclear due to the overlapping of both images, it is necessary to remove the latent image element group (6) in the area overlapping the unique information (2) in white. In this specification, for easy illustration, FIG. 7 shows the latent image element group (6´) before being removed in white.

[0037] In order to generate vertical moiré as in the first embodiment of the present invention, the latent image element group (6´) is formed in a line (line drawing) shape or a dot (pixel) shape, similar to the phosphorescent element group (4). When formed in a dot (pixel) shape, since the density of the phosphorescent element (7) becomes low and the visibility decreases, it is desirable to form it in a line (line drawing) shape.

[0038] In order for the latent image element group (6´) to interfere with the phosphorescent element group (4) to generate moiré, a plurality of latent image elements (11) need to be arranged with a regularity different from the regularity of the arrangement of the phosphorescent elements (7). The different regularity means that at least one of the arrangement pitch, arrangement direction, and element arrangement angle is applied. In the first embodiment of the present invention, the regularity regarding the arrangement pitch and arrangement angle of the latent image elements (11) is different from the regularity of the arrangement of the phosphorescent elements (7). As an example, the latent image elements (11) are arranged with an arrangement pitch (P2) different from the arrangement pitch (P1) of the phosphorescent element group (4), the arrangement direction is the same in the first direction (S1 direction), but the arrangement angle of the latent image elements (11) is inclined by 1 degree with respect to the phosphorescent elements (7).

[0039] In the above, as the "different" range, for example, in the case of the arrangement pitch, it is 80% to 120% of the arrangement pitch of the luminescent element group (4), and in the case of the arrangement direction or the arrangement angle, the range within ±5 degrees is regarded as the different range. Note that the arrangement direction and the angle of the element can also be treated as the same parameter depending on the definition method, and it is not necessarily necessary to consider them separately.

[0040] As described above, the latent image element group (6) and the unique information (2) are combined to form the variable image group (5). In order to visualize the variable image group (5), different optical characteristics may be imparted to the luminescent element group (4) around the variable image group (5). Different optical characteristics mean, for example, any optical difference such as a difference in the amount of reflected light (diffracted light) from the luminescent element group (4), a difference in the reflection angle (diffraction angle) of light, or absorption of different light. Since the luminescent element group (4) and the variable image group (5) have different optical characteristics, the information included in the variable image group (5) is visualized as an image captured by the observer's eyes. The above is the explanation of the variable image group (5).

[0041] Next, a method for producing the luminescent moving image pattern (1) will be described. The method for producing the luminescent moving image pattern (1) of the present invention sets the regularity of the luminescent element (7) composed of the diffraction grating (8) of the luminescent element group (4), creates unique information data that is the basis of the unique information of the variable image group (5) and latent image element group data that is the basis of the latent image element group (6) by an image processing device, synthesizes the unique information data and the latent image element group data to create variable image group data, uses the created variable image group data, removes or destroys the metal film (10) of the luminescent element group (4) by laser irradiation to form the variable image group (5), and has a step of combining the luminescent element group (4) and the variable image group (5) (not shown).

[0042] In order to remove the metal film (10) of the aforementioned group of luminescent elements (4) or to break the metal film (10) and impart optical characteristics different from those of the group of luminescent elements (4) to the variable image group (5), as an example, as shown in FIG. 8, by drawing the variable image group (5) on the group of luminescent elements (4) with a laser irradiation device (12), different optical characteristics are imparted. By laser irradiation, the metal film (10) on the hologram forming layer (9) of the group of luminescent elements (4) is removed to expose the hologram forming layer (9), or even if it cannot be completely removed, by damaging a part of the metal film (10), the amount of diffracted light generated from the variable image group (5) is reduced, or the reflectance of the metal film (10) is reduced, thereby imparting different optical characteristics. Thereby, a variable image group (5) having different optical characteristics can be imparted to the group of luminescent elements (4) and visualized. The laser irradiation device (12) may be a general industrial laser processing machine, or there is no problem even if it is a general-purpose processing machine called a cheaper laser marker.

[0043] In the method for producing the luminescent moving image pattern (1) of the present invention, it is a great advantage that all of the variable image group (5) can be written simultaneously to the group of luminescent elements (4) to which no information has been imparted at all. In particular, when a simple pattern such as a moiré pattern is used as the dynamic information (3) as in the first embodiment of the present invention, the ability to write all the information of the variable image group (5) at once is an effective means for preventing the forgery and counterfeiting of variable information.

[0044] Note that the method for producing the luminescent moving image pattern (1) of the present invention is not limited to a laser as long as it is a means capable of removing or damaging the metal film (10) applied on the hologram forming layer (9) on demand. It can also be an electron beam, radiation, mechanical cutting, etc., or as one of the conventional demetallization methods for removing the metal film (10), a method of performing mask printing by gravure or screen printing and immersing it in a chemical solution to remove aluminum other than the masked area is also possible.

[0045] The effect of the luminescent moving image pattern (1) of the present invention is shown in Fig. 9. When the luminescent moving image pattern (1) is observed in an environment where diffracted light is generated, as shown in Fig. 9(a), the face image and personal number of the holder, which are the unique information (2), are visualized, and moiré that moves as a striped pattern appears as dynamic information (3) in the background of the unique information (2). From this observation angle, by slightly tilting the luminescent moving image pattern (1), as shown in Fig. 9(b), the position of the moiré in the first direction (S1 direction), which is the striped pattern in the background of the unique information (2), changes. By further tilting the luminescent moving image pattern (1), as shown in Fig. 9(c), the position of the moiré in the first direction (S1 direction), which is the striped pattern in the background of the unique information (2), further changes. As described above, the position of the unique information (2) representing the face image and personal number of the holder does not change, and only the position of the dynamic information (3) adjacent to its background in the first direction (S1 direction) changes. Among these movements, a sense of depth that exists deeper than the unique information (2) is generated in the moiré, which is the dynamic information (3) (not shown).

[0046] Next, the principle by which the above-described effect is produced will be explained. With respect to the angle of the incident light, a diffraction grating (8) in the luminescent element (7) that forms an angle orthogonal to the light reflects the light particularly strongly to generate strong diffracted light. As a result, as shown in Fig. 4, the position of the regions (A-1, A-2, A-3) in the luminescent element (7) that emit particularly strong diffracted light changes according to the change in the angle of the incident light. First, in the case of Fig. 9(a), it is assumed that the region (A-1) of the luminescent element (7) shown in Fig. 4 emits strong diffracted light.

[0047] Among the variable image group (5), the unique information (2) representing the face image and personal number of the holder is not formed by the regular arrangement of the latent image elements (11) that form the latent image element group (6). Therefore, no matter from which angle the light is incident, it is visualized as it is, and basically the appearance does not change. On the other hand, in the latent image element group (6), only the region where the latent image element (11) exists on the position where strong diffracted light is generated becomes a state where the diffracted light is relatively weak. As a result, a difference in the intensity of the diffracted light occurs between this region and the regions where the diffracted light is strong, and as a result, only a part of the latent image element group (6) that interferes with the luminescent element group (4) is sampled and visualized.

[0048] In this case, since the latent image elements (11) in the latent image element group (6) are arranged with a different regularity from the luminescent elements (7) in the luminescent element group (4), the image sampled and visualized becomes a moiré pattern which is an interference fringe caused by a slight deviation in the regularity between the luminescent element group (4) and the latent image element group (6). As a result, as shown in Fig. 9(a), the face image and personal number of the holder, which are the unique information (2), are visualized, and moiré that moves as a striped pattern appears as the dynamic information (3) in the background of the unique information (2).

[0049] Subsequently, from the state of Fig. 9(a), the luminescent video pattern (1) is tilted, and by changing the angle of the incident light, the region that emits particularly strong diffracted light in the luminescent element (7) changes to the position of (A-2) of the luminescent element (7) shown in Fig. 4. As a result, the position of the latent image element (11) sampled and visualized also changes, and the position of the moving moiré (dynamic information (3)) generated by the interference between the luminescent element group (4) and the latent image element group (6) also changes. Thereby, as shown in Fig. 9(b), a so-called video effect occurs in which the position of the moiré, which is the dynamic information (3) adjacent to the unique information (2), changes.

[0050] Furthermore, when the luminescent video pattern (1) is tilted from the state of Fig. 9(b), the region that emits particularly strong diffracted light in the luminescent element (7) changes to the position of (A-3) of the luminescent element (7) shown in Fig. 4. As a result, the position of the latent image element (11) visualized also changes further, and the position of the moving moiré (dynamic information (3)) also changes. As shown in Fig. 9(c), the position of the moiré, which is the dynamic information (3) adjacent to the unique information (2), changes further. The above is the principle in the luminescent video pattern (1) of the present invention in which the unique information (2) and the dynamic information (3) are visualized, and a video effect is produced in the dynamic information (3) by tilting the luminescent video pattern (1).

[0051] Also, the sense of depth in moiré occurs because binocular parallax acts on an image with movement in the horizontal direction (first direction). If the moiré moved in the direction perpendicular to the first direction, the binocular parallax would not function, and thus this sense of depth would not occur. The luminous moving image pattern (1) of the present invention produces this sense of depth when the arrangement pitch (P2) of the latent image element group (6) is set to a value larger than the arrangement pitch (P1) of the luminous element group (4). Conversely, when the arrangement pitch (P2) of the latent image element group (6) is set to a value smaller than the arrangement pitch (P1) of the luminous element group (4), this sense of depth is reversed, and a sense of proximity as if it exists in the foreground occurs. The magnitudes of these senses of depth and proximity can also be controlled. The closer the pitch (P2) of the latent image element group (6) is to the arrangement pitch (P1) of the luminous element group (4), the greater the sense of depth and proximity become.

[0052] Note that although the closer the pitch (P2) of the latent image element group (6) is to the arrangement pitch (P1) of the luminous element group (4), the greater the sense of depth and proximity become, it is necessary to note that the number of moirés that appear decreases, and the moiré pattern becomes blurred and unclear. It is necessary to appropriately set each arrangement pitch in consideration of these factors.

[0053] The sense of depth and proximity such as the sense of depth and the sense of proximity that occur as secondary effects of the moving image effect of the luminous moving image pattern (1) of the present invention are instantaneously established in the observer's brain at the moment of observing the luminous moving image pattern (1). The authenticity discrimination based on the presence or absence of the sense of depth and proximity is such that the observer can unconsciously and instantaneously perform high-precision authenticity discrimination. This is fundamentally different from other authenticity discrimination means involving large actions such as watermarking or tilting. Most of the conventional authenticity discriminations required prior knowledge of "when viewing in this way, such an image appears at this location in the printed matter."

[0054] For example, in the case of a watermark, if there is no knowledge such as "when viewed through the watermark, a portrait of a man appears in the center of the printed matter", it is impossible to determine the authenticity itself. However, for a sense of depth such as perspective and a more advanced three-dimensional effect like 3D, "seeing" alone is the action for authenticity discrimination, and even without prior knowledge, the observer can recognize that it is three-dimensional at the moment of seeing the printed matter. Also, in many cases, when a sense of perspective is created in the printed matter, the observer will view the image with surprise, which will remain in the observer's impression and memory for a long time, and the authenticity discrimination will function more efficiently in subsequent scenes.

[0055] In the luminous moving image pattern (1) of the present invention, in order to apply the authenticity discrimination method using this sense of perspective, it is necessary to make the binocular parallax function. For this purpose, it is important to design the moving direction of the dynamic information (3) appearing on the luminous moving image pattern (1) in a direction parallel to both eyes of the observer, that is, in the horizontal direction (the first direction) or at an angle close to it. It utilizes the fact that a sense of foreground and depth is automatically generated by binocular parallax in the human brain for an image moving in the horizontal direction (the first direction).

[0056] In this first embodiment, the variable image group (5) imparted by a laser is in a form that combines two images with different properties of the unique information (2) and the dynamic information (3). The unique information (2) is "variable information (individual information)" that needs to be changed each time with individual information such as the face image of the holder and the personal number of the holder. On the other hand, one of the dynamic information (3) is a moiré pattern which is "fixed information" that does not need to change the information individually. In this first embodiment, at the stage of generating the variable image group (5), while replacing the variable information such as the face image of the holder and the personal number that are the basis of the unique information (2) each time, the latent image element group (6´) in the background is used as fixed information which is an image common to all variable image groups (5). Therefore, the variable image group (5) of the present invention can be generated with the least amount of effort.

[0057] In addition, when the variable image group (5) is drawn on the luminescent element group (4) with a laser, the form of the image data of the variable image group (5) may be vector data or raster data. The data may be converted according to the data format of the device that the user uses for demetallization, and data such as Ai, EPS, PDF, and DXF, or data such as Tiff, BMP, and JPEG may be used.

[0058] Also, when the variable image group (5) is formed as a gradation image (shading change), it is formed by changing the ratio of the area of the laser-irradiated portion (dots, lines) to the area of the non-irradiated portion, changing the ratio midway, or gradually changing the ratio.

[0059] In the first embodiment, the variable image group (5) is formed by the dynamic information (3) and the unique information (2). However, not only the moiré pattern of the background, but also the face image of the holder and the personal number of the holder can be formed as the dynamic information (3). Therefore, the variable image group (5) may be formed only by the dynamic information (3).

[0060] On the other hand, individual information such as a face image has a complicated shading and requires a high image resolution. In addition to the need to arrange the luminescent elements (7) forming the luminescent element group (4) at a high density (small pitch), time is also required for the process of converting to a line configuration for imparting a moving image effect. In that case, a configuration in which the non-moving "variable information" and the moving "fixed information" are adjacent to each other, as in the first embodiment, is effective and practical. In the configuration in which the non-moving "variable information" and the moving "fixed information" are adjacent to each other, as shown in FIG. 10, it is important to have a completely gapless configuration without providing a space between the unique information (2) and the dynamic information (3).

[0061] For example, as shown in FIG. 11(a), when a forged hologram (C1) having a configuration in which a certain space exists between the unique information (2) and the dynamic information (3) is used, a forger may prepare in advance a moiré hologram (B1) in which the moiré, which is the dynamic information (3), and the area where the unique information (2) is printed are provided separately.

[0062] In the field of holograms, simple patterns such as moiré can be easily produced in advance. For a moiré hologram (B1) with moiré applied in advance, if only the unique information (2) is printed, a forged hologram (C1) can be easily forged. Therefore, as shown in FIG. 10, it is important to have a configuration in which there is no space between the unique information (2) and the dynamic information (3) and they are in complete contact without any gaps. When the unique information (2), which is variable information, and the latent image element group (6) are configured without any gaps, it is necessary to draw the unique information (2) and the latent image element group (6) simultaneously. Therefore, it becomes difficult to forge by only tampering with a part of the variable information of the hologram.

[0063] Also, in the first embodiment, it is desirable to avoid expressing variable information such as symbols and characters to be imparted only in the form of black painting. As one of the methods of forging this luminous moving image pattern (1), as shown in FIG. 11(b), it is considered that a moiré hologram (B2) with only the background moiré pattern applied in advance is prepared, and a means for printing only the unique information (2) thereon is used. When using a configuration of white-out characters with black outlines as in the first embodiment, the moiré pattern of the moiré hologram (B2) overlaps the white-out character area or the white area of the face image of the forged hologram (C2), resulting in a difference from the genuine product.

[0064] However, when all the characters and images are black-painted images, there is no state where the applied characters and images overlap with the moiré pattern, so it is difficult for an obvious difference to occur between the forged hologram (C2). As described above, the anti-forgery resistance can be improved only by structural devises such as having a configuration in which there is no space between the unique information (2) and the dynamic information (3) and they are in complete contact without any gaps, or using images and characters with white-out.

[0065] Also, under diffused reflected light, which is a condition where diffracted light does not occur (hereinafter referred to as "under diffused reflected light"), the visibility of the unique information (2) and the dynamic information (3) can be improved. When the phosphorescent moving image pattern (1) is simply attached to the base material (13), when observed under conditions where diffracted light occurs, as shown in Fig. 12(b), it has an appropriate appearance. On the other hand, when observed under diffused reflected light, as shown in Fig. 12(a), it is visually recognized with the light and dark of the image inverted. There is no problem with the light and dark of letters, symbols, etc. being inverted, but in general, it is not desirable for the light and dark of a face image to be inverted.

[0066] As shown in Fig. 13, it is desirable to provide an opaque visible light absorption layer (14) between the base material (13) and the phosphorescent moving image pattern (1) so that the light and dark of a face image, etc., can be seen normally even under diffused reflected light. The opaque visible light absorption layer (14) must not be completely transparent. It only needs to have the characteristic of absorbing visible light relatively more than the surrounding metal film (10) under diffused reflected light and in an environment where diffracted light occurs. This opaque visible light absorption layer (14) may simply be a form where the base material (13) is printed in a dark color, or a dark base material is sandwiched in the middle, or it may be a form where a dark layer is incorporated into the phosphorescent moving image pattern (1) in advance. Thereby, the problem of being visually recognized with the light and dark inverted under diffused reflected light can be avoided.

[0067] Also, the dynamic information (3) in this first embodiment is a simple moiré of a striped pattern, but a moiré magnification phenomenon can be made to act on significant information with a more complex shape to obtain the dynamic information (3). For example, arbitrary figures with more complex shapes such as the circular moiré shown in Fig. 14(a) and the star-shaped moiré shown in Fig. 14(b) can be used as the dynamic information (3).

[0068] In the first embodiment, since the vertical moiré pattern which is the dynamic information (3) has a very simple configuration, the concept of compressing the base image to form the latent image elements (11) can also be applied. The base image (15) refers to the image that is intended to appear as the dynamic information (3) in the luminescent video pattern (1). In this case, one stripe pattern of the dynamic information (3) is set as the base image. The latent image element (11) is obtained by compressing the entire one stripe pattern and then mirror-inverting it with the vertical direction as the axis in the first direction (S1 direction). It can be said that the latent image elements (11) are continuously arranged at a pitch (P2) slightly larger than the arrangement pitch of the luminescent element group (4) to form the latent image element group (6´).

[0069] Next, the configuration of the latent image element group (6´) using the above-mentioned base image (15) will be described using a specific example of generating a star-shaped moiré pattern. As shown in FIG. 15, an image that is intended to appear on the luminescent video pattern (1) as the dynamic information (3) is set as the base image (15). In the first embodiment, the figure of the star is the base image (15). The entire base image (15) is compressed at a specific reduction ratio in the first direction (S1 direction) to obtain the latent image element (11). The criterion for compression is that at least the entire latent image element (11) needs to fit within the arrangement pitch (P2, P3). Therefore, the reduction ratio is set to be lower than the arrangement pitch of the latent image element group (6´) at least minimally. In the example shown in FIG. 15, the arrangement pitch (P2) is a pitch slightly smaller than the arrangement pitch (P1) of the luminescent element group (4), and the arrangement pitch (P3) is configured to be a pitch slightly larger than the arrangement pitch of the luminescent element group (4).

[0070] The latent image elements (11) produced by the above procedure are arranged with a regularity different from the regularity of the arrangement of the phosphorescent element group (4) to form a latent image element group (6´). Even if it is significant information, due to the moiré magnification phenomenon, it appears as an enlarged moiré representing the significant information. In the method of changing the regularity, the easiest is to change the arrangement pitch. Also, by adjusting the arrangement pitch, not only the video effect but also the sense of perspective can be controlled. Note that when arranging with a pitch (P3) larger than the arrangement pitch of the phosphorescent element group (4), it is necessary to note that each latent image element (11) needs to be mirror-inverted. As a more specific configuration method for expressing significant information by moiré, the configuration described in Japanese Patent No. 5131789 may be used.

[0071] Next, as a second embodiment, a form will be described in which the phosphorescent moving image pattern (1) is configured using dot (pixel)-shaped phosphorescent elements (7) instead of line (lined)-shaped phosphorescent elements (7). Matters common to the first embodiment will be omitted from the description.

[0072] (Second Embodiment) Fig. 16 shows a dot-shaped phosphorescent moving image pattern (1). The second embodiment will describe a configuration in which dynamic information (3) is generated using a moving moiré by using dot-shaped phosphorescent elements (7) composed of pixels.

[0073] As shown in Fig. 17, the phosphorescent moving image pattern (1) in this second embodiment is composed of a combination of two element groups, a dot-shaped phosphorescent element group (4) and a variable image group (5). The variable image group (5) has a dot-shaped latent image element group (6) that is the basis of the moiré pattern of the letter "A" which is the specific information (2) and the dynamic information (3).

[0074] First, the dot-shaped luminous element group (4) will be described with reference to FIG. 18. The luminous element group (4) is composed of a set of luminous elements (7), similar to the first embodiment. The luminous element (7) is composed of a diffraction grating (8) which is a set of minute optical elements with high reflectivity. In this second embodiment, the dot-shaped luminous elements (7) are regularly arranged at a first pitch (P1) in a first direction (S1 direction) and a second direction (S2 direction) orthogonal to the first direction, respectively. Note that it is not necessary for the first direction (S1 direction) and the second direction (S2 direction) to have the same pitch, and different pitches are also acceptable.

[0075] The characteristics required for the dot-shaped luminous element (7) in this second embodiment are the same as those of the linear luminous element (7) in the first embodiment. In the linear luminous element (7) shown in the first embodiment, the region where diffracted light is generated moves in the first direction (S1 direction), while in the dot-shaped luminous element (7), the region where diffracted light is generated moves in the first direction (S1 direction) and / or the second direction (S2 direction). For a continuous angular change of the incident light, the diffracted light may continuously move in a corresponding manner, and the moving direction is not particularly limited.

[0076] Also in the dot-shaped luminous element (7), in order to satisfy the above optical characteristics, the shape of the diffraction grating (8) in the luminous element (7) is important. FIGS. 19(a) to 19(d) and FIGS. 20(a) to 20(d) show an example of the shape of the diffraction grating (8) for satisfying the above-mentioned optical characteristics. The luminous element (7) in FIG. 19(a) is formed by continuously arranging concentric diffraction gratings (8), and the luminous element (7) in FIG. 19(b) is formed by arranging linear diffraction gratings (8) in a concentrated linear manner. The luminous element (7) in FIG. 19(c) is formed by arranging curved diffraction gratings (8) in a concentrated linear manner, and the luminous element (7) in FIG. 19(d) has the same concentric diffraction grating (8) as in FIG. 19(a), but pseudo-concentric circles are formed by a set of straight lines with slightly different angles.

[0077] In the example of the four types of luminescent elements (7) shown in Fig. 19, since there are two diffraction gratings (8) forming right angles to the light incident from one direction existing simultaneously at two locations, bright spots (α1, α2) that strongly diffract light appear simultaneously at two locations within the luminescent element (7). For this reason, when forming a luminescent moving image pattern (1) using the luminescent element (7) shown in Fig. 19, two pieces of dynamic information (3) always appear as a pair, and the respective pieces of dynamic information (3) move in opposite directions to each other.

[0078] When the above-described configuration is such that two pieces of dynamic information (3) appear as a pair, depending on the pattern and movement of the dynamic information (3), there may be a case where the dynamic information (3) overlaps and it becomes difficult for the observer to recognize. In order to prevent this, a configuration of the luminescent element (7) as shown in Fig. 20 may be used. Fig. 20 shows an example of a luminescent element (7) configured such that only one bright spot is generated for the light incident from one direction. Fig. 20(a) shows an example of a Fresnel type, and Fig. 20(b) shows an example of a blazed type diffraction grating (8). By imparting a certain directionality to any fine three-dimensional cross-sectional shape, it is possible to make the bright spot generated from the luminescent element (7) a single one. Also, as shown in Fig. 20(c) and Fig. 20(d), a form may be used in which the bright spot generated by the incident light from one direction is limited to one location by restricting the angular range of the diffraction grating (8) from 0 degrees to 180 degrees. The difference between Fig. 20(c) and Fig. 20(d) is whether the density also changes simultaneously with the angle of the diffraction grating (8).

[0079] Subsequently, the latent image element group (6) that is the basis of the dynamic information (3) of the variable image group (5) will be specifically described with reference to Fig. 21.

[0080] Similar to the first embodiment described above, it is necessary to remove the latent image element group (6) in the area overlapping with the unique information (2) in white. For the sake of simplicity of the explanatory drawing, Fig. 21 shows the latent image element group (6´) before being removed in white. In order to generate moiré of the alphabet "A" as in the second embodiment, the latent image element group (6´) is dot-shaped like the phosphorescent element group (4), and the characters of the alphabet "A" to be presented are used after being compressed as a whole (in the vertical and horizontal directions).

[0081] In the second embodiment, since it is intended to generate moiré of the alphabet "A" in the phosphorescent video pattern (1), the base image (15) is the alphabet "A". And by compressing this base image (15) as a whole, the latent image elements (11) constituting the latent image element group (6´) are obtained.

[0082] In order for the latent image element group (6´) to interfere with the phosphorescent element group (4) to generate moiré, a plurality of latent image elements (11) need to be arranged with a regularity different from the regularity of the arrangement of the phosphorescent element group (4). In the second embodiment, the regularity regarding the arrangement pitch of the latent image elements (11) having the shape of the alphabet "A" is different from the regularity of the arrangement of the phosphorescent element group (4). The latent image elements (11) are arranged in the first direction (S1 direction) and the second direction (S2 direction) with an arrangement pitch (P2) different from the arrangement pitch (P1) of the phosphorescent element group (4).

[0083] Note that also in the second embodiment, by controlling the arrangement pitch (P2) of the dot-shaped latent image elements (11) in the first direction (S1 direction), in addition to the video effect, the sense of depth such as a sense of depth and a sense of foreground can be controlled.

[0084] Also, as an example for expressing with moiré, in the second embodiment, the pitch (P2) of the latent image elements (11) in the first direction (S1 direction) is set to a numerical value of 103% with respect to the arrangement pitch (P1) of the phosphorescent elements (7). The latent image element group (6) and the unique information (2) as described above are combined to form the variable image group (5).

[0085] Note that the appearance of the dynamic information (3) changes depending on whether the latent image element group (6) in the variable image group (5) is represented in negative (the moiré is bright) or positive (the moiré is dark). Although the description of the first embodiment in which the moiré is represented in a so-called positive state darker than the surroundings has been omitted, the dynamic information (3) that appears can be represented either as positive or as the reverse negative. When the variable image group (5) is configured with the latent image element group (6) as negative, the dynamic information (3) that appears is negative, and when the variable image group (5) is configured with the latent image element group (6) as positive, the dynamic information (3) that appears is positive. In this second embodiment, since it is represented as positive, the dynamic information (3) that appears is represented as positive. The above is the description of the variable image group (5).

[0086] Fig. 22 shows the overlapping state of the phosphorescent element group (4) and the latent image element group (6') in the variable image group (5). Note that Fig. 22 is a deformed image with the pitch deviation deliberately emphasized. Since the regularity of the phosphorescent element group (4) and the regularity of the latent image element group (6') are different, a periodic deviation occurs between the two elements, generating moiré. Also, for a more specific configuration method for expressing significant information as dot-like moiré, the configuration described in Japanese Patent No. 5131789 may be used.

[0087] The effect of the luminescent moving image pattern (1) of the second embodiment is shown in FIG. 23. In this example, it is assumed that the concentric circular luminescent elements (7) in FIG. 19(a) are used. When observing the luminescent moving image pattern (1) in an environment where diffracted light is generated from the hologram, as shown in FIG. 23(a), the face image and personal number of the holder, which are the specific information (2), are visualized. As dynamic information (3) in the background of the specific information (2), two moving moirés representing the letter "A" of the alphabet form a pair and appear periodically in plural. Next, as shown in FIG. 23(b), by slightly tilting the luminescent moving image pattern (1), the relative positional relationship of the moving moirés representing the letter "A" of the alphabet in the background of the specific information (2) changes. Further, as shown in FIG. 23(c), by further tilting the luminescent moving image pattern (1), the position of the moving moirés representing the letter "A" of the alphabet in the background of the specific information (2) changes further. Basically, in this form, the letter "A" of the alphabet appears to be rotating relative to each other.

[0088] Next, as a third embodiment, a form of forming the dynamic information (3) using the line configuration of the IP image method, which is a form of a stereoscopic image imaging method different from the form using the moiré magnification phenomenon, will be described.

[0089] (Third Embodiment) First, a form in which the luminescent element (7) is in a linear shape and the dynamic information (3) is configured in a configuration that divides and compresses the base image (15) of the IP image method to exhibit a moving image effect will be described.

[0090] In the form of giving a moving image effect to the dynamic information (3) by utilizing the above-described moiré magnification phenomenon, since the enlarged moiré patterns always appear periodically in plural, it is an unfavorable configuration for users who do not desire a design in which the same information is repeatedly displayed. Further, in order to utilize the moiré magnification phenomenon, since it is necessary to compress and reduce the entire information represented by the latent image element (11) in a very narrow pitch that is almost the same as the arrangement pitch of the luminescent element group (4), the moiré patterns that can be made to appear are easily limited to relatively simple patterns, and there are significant structural constraints for moving an image that requires high resolution.

[0091] The configuration for producing the video effect of the IP image method in this specification eliminates many constraints associated with the moiré magnification phenomenon and provides a high degree of design freedom.

[0092] Fig. 24 shows the luminous video pattern (1) in the third embodiment. In this third embodiment, the luminous video pattern (1) represents the Chinese characters "Printed Flower Child", which is variable information that needs to be rewritten for each holder, and this variable information itself becomes dynamic information (3) that produces a video effect. In the first and second embodiments, by combining the "variable information (holder's information)" that does not move and the "fixed information (moiré)" that moves, it is possible to achieve both variable information addition and video effect on the hologram. However, in this third embodiment, it is a more advanced form in which the "variable information (holder's information)" itself is the dynamic information (3).

[0093] The outline of the structure of the luminous video pattern (1) in this third embodiment is shown in Fig. 25. The luminous video pattern (1) consists of a luminous element group (4) and a variable image group (5). Since there is no unique information (2) in the luminous video pattern (1) of this third embodiment, the variable image group (5) directly becomes the latent image element group (6). In this third embodiment, this latent image element group (6) consists of two latent image element groups (6A, 6B), namely, the first latent image element group (6A) representing the Chinese characters "Printed" which is the surname, and the second latent image element group (6B) representing the Chinese characters "Flower Child" which is the given name. Note that in this third embodiment, it is not necessarily the case that unique information (2) should not be provided. Unique information (2) can be provided as needed and combined with the latent image element group (6).

[0094] Next, the latent image element group (6) will be described. In this third embodiment, "Printed" is used as the first base image (15A), and "Flower Child" is used as the second base image (15B). The reason for separately setting the base images (15A, 15B) is to apply a configuration that changes the movement direction of each of the emerging dynamic information (3) in order to more strongly emphasize the video effect and sense of perspective.

[0095] First, the configuration of the basic latent image element group (6) will be described. The latent image element group (6) is formed by arranging a plurality of latent image elements (11A, 11B) obtained by dividing the base image (15) with a specific width and compressing it at a specific reduction ratio, with the same regularity as the regularity of the phosphorescent element group (4). That is, the latent image element group (6) needs to be continuously arranged at the same pitch (P1) as the phosphorescent element group (4), in the same arrangement direction (S1 direction), and at the same angle. This is the biggest difference from the form using the moiré magnification phenomenon described above.

[0096] In the configuration of the latent image element group (6) of the IP image method, each latent image element (11) has a different shape. To form the latent image elements (11A, 11B), first, frames (16A, 16B) of a certain size are applied to the base images (15A, 15B), and only the image inside this frame (16A, 16B) is divided and extracted. By compressing this image at a specific reduction ratio, one latent image element (11A, 11B) can be generated. When producing an adjacent latent image element (11A, 11B), the position of the frame (16) is moved in the first direction by the arrangement pitch (P1) of the phosphorescent element group (4), and only the image inside the frame (16A, 16B) is divided and extracted again. By compressing the image at a specific reduction ratio, another adjacent latent image element (11A, 11B) can be generated. This is arranged at a position shifted by the pitch (P1) in the first direction adjacent to the previous latent image element (11A, 11B).

[0097] As described above, the frame (16A, 16B) is moved to divide and compress the base image (15A, 15B) to create and arrange the latent image elements (11A, 11B). This process is repeated. When the base image (15) is no longer included in the moved frame (16A, 16B), the latent image element group (6) is finally completed.

[0098] Next, the specific configuration of the latent image element group (6) and its manufacturing method will be described in detail. First, the "printing", which is the base image (15A, 15B) of the first latent image element group (6A), was fitted with a frame (16A) of a certain size and compressed at a certain reduction ratio. As an example, in this third embodiment, the reduction ratio is 10%, which is a fairly large value. Generally, the horizontal width of a hologram in circulation is often 20 mm or less. When intending to store the dynamic information (3) therein, basically, a reduction ratio of about 0.1% to 20% is desirable.

[0099] However, the reduction ratio needs to be appropriately set according to various factors such as the size of the hologram, the resolution required for reproducing the base image (15), and the width of the movement desired by the user. The position of the frame (16A) is moved by the pitch (P1) of the phosphorescent element group (4) in the first direction (S1 direction) each time, and the split compression is repeated to produce the first latent image element group (6A).

[0100] For the second latent image element group (6B), the "Hanako", which is the base image (15B), was fitted with a frame (16B) of a certain size and compressed at a certain reduction ratio. Here, it is compressed to the same 10% as the first latent image element group (6A). Here, it is desirable to mirror-invert the image of the compressed latent image element (11) with respect to the axis perpendicular to the first direction (S1 direction). The position of the frame (16B) is moved by the pitch (P1) of the phosphorescent element group (4) in the first direction (S1 direction) each time, and the split compression is repeated to produce the second latent image element group (6B). However, all the latent image elements (11) of the second latent image element group (6B) have a configuration in which the base image (15B) is split-compressed and then mirror-inverted. This is the biggest difference in configuration between the first latent image element group (6A) and the second latent image element group (6B). Hereinafter, an example using a configuration with mirror inversion as a desirable form will be described, but the latent image element (11) may be formed without mirror inversion.

[0101] Note that although the same numerical values are used within each of the latent image element groups (6A, 6B) for the size and reduction ratio of the frame (16), it is not necessary to use the same numerical values when applying them to separate latent image element groups (6) such as the first latent image element group (6A) and the second latent image element group (6B), and any numerical values can be set. The larger the size of the frame (16) and the smaller the reduction ratio, the larger the width and speed of the movement of the moving image effect of the dynamic information (3) that appears. However, inversely proportional to this, the resolution of the dynamic information (3) decreases and it appears blurred. These numerical values need to be appropriately set in consideration of the complexity and magnitude of movement of the base image (15).

[0102] In the form using the above-described moiré magnification phenomenon, since it was necessary to simply compress the entire base image (15) and fit it within the arrangement pitch, there were cases where an image with a complex base image (15) requiring a high resolution could not be reproduced. However, when forming the latent image element group (6) by the IP image method, since the size of the image to be compressed can be adjusted by adjusting the size of the frame (16), the constraints on the reproducible image are reduced.

[0103] The image used for the base image (15) may use characters, numerical values, symbols, marks, etc., and there are no particular restrictions. It is also possible to use a photographic image such as a human face or a landscape as the base image (15). The base image (15) is reproduced as an image having a moving image effect on the luminous moving image pattern (1) as the dynamic information (3). Note that the configuration of the latent image element group (6) by the IP image method in this specification is a method of pseudo-configuring an image recorded and reproduced through a slit-shaped lenticular or dot-shaped microlens array by image processing, which is one of the methods for capturing and reproducing a stereoscopic image.

[0104] Note that also in this third embodiment, the method of imparting a configuration in which the luminous element group (4) and the variable image group (5) have different optical characteristics is the same as in the first and second embodiments, and as shown in FIG. 27, it is performed by drawing the variable image group (5) on the luminous element group (4) with the laser irradiation device (12).

[0105] Next, the ideal overlapping configuration of the luminescent element group (4) and the latent image element group (6) is shown in FIG. 28. FIG. 28 shows the most desirable overlapping configuration in which there is no misalignment between the luminescent elements (7) and the respective latent image elements (11), and the centers of the respective latent image elements (11) overlap the centers of the respective luminescent elements (7). Note that if the centers of the respective latent image elements (11) cannot be arranged to overlap the centers of the respective luminescent elements (7) and the centers are misaligned, the width of the movement of the dynamic information (3) may become smaller or the movement may become discontinuous. Even in this state, the video effect itself is produced and the effects intended by the present invention are produced. However, it is more desirable to draw the variable image group (5) so that there is no misalignment between the positions of the luminescent element (7) and the respective latent image elements (11).

[0106] However, when forming the variable image group (5) with a laser later with respect to the luminescent element group (4) that is previously attached to a card or printed matter, it is difficult to adjust the positional relationship of the overlap between the luminescent element group (4) and the latent image element group (6). In that case, even if the centers of the respective latent image elements (11) do not overlap the centers of the respective luminescent elements (7), a special line drawing configuration can be used to prevent the problem that the width of the movement of the dynamic information (3) becomes smaller or the movement becomes discontinuous.

[0107] Next, FIG. 29 shows a latent image element group (6AB) with a desirable special line drawing configuration for solving the above problem. This latent image element group (6AB) is obtained by dividing, for the same base image (15A), the latent image element group (6A) produced without mirror-inverting the latent image element (11A) and the latent image element group (6B) produced by mirror-inverting the latent image element (11A) by half the pitch width (1 / 2*P1) for each pitch in the first direction (S1 direction), and synthesizing the two divided latent image element groups (6A, 6B) shifted by half a pitch as shown in the enlarged view, and has a special line drawing configuration.

[0108] This special latent image element group (6AB) is formed by combining latent image element groups (6A, 6B) that move in opposite directions to each other, so that the starting and ending points of the movement of the base image (15) in the latent image element group (6AB) disappear, and the appearance of the base image (15) continues to move without stopping, resulting in a line drawing configuration.

[0109] By using this special latent image element group (6AB), even if it is not possible to draw the center of each latent image element (11) to overlap the center of each luminescent element (7), problems such as the width of the movement of the dynamic information (3) becoming smaller or the movement becoming discontinuous do not occur. Therefore, there is no need to adjust the positional relationship between the two element groups so that the center of each latent image element (11) overlaps the center of each luminescent element (7). Thus, this special latent image element group (6AB) is a more appropriate line drawing configuration of the latent image element group (6) when the variable image group (5) is drawn later with a laser on the luminescent element group (4) that is pre-attached to a card or printed matter. A more specific configuration and manufacturing method are as described in Japanese Patent Application Laid-Open No. 2016-203459, and this technology may be applied to the latent image element group (6) of the present invention.

[0110] Next, the effect of the luminescent moving image pattern (1) of the third embodiment of the present invention will be described with reference to FIG. 30. FIG. 30 shows the latent image element group (6A) having the normal configuration of FIG. 26 as the variable image (5A), and the effect when arranged so that the center of each latent image element (11) overlaps the center of each luminescent element (7) as shown in FIG. 28.

[0111] When the diffractive light-emitting moving image pattern (1) is observed in an environment where diffracted light is generated, moving information (3A, 3B) representing the Chinese characters "Printing" and "Hanako" appears as shown in Fig. 30(a). By slightly tilting the diffractive light-emitting moving image pattern (1), the relative positional relationship between "Printing" and "Hanako", which are the moving information (3A, 3B), changes as shown in Fig. 30(b). "Printing" and "Hanako" move in opposite directions at the same speed. By further tilting the diffractive light-emitting moving image pattern (1), the relative positional relationship between "Printing" and "Hanako", which are the moving information (3A, 3B), further changes and appears as shown in Fig. 30(c). Similarly, "Printing" and "Hanako" move in opposite directions at the same speed. Also, a sense of foreground is created such that the characters of "Printing" appear relatively in the foreground, a sense of depth is created such that the characters of "Hanako" appear relatively in the background, and a sense of perspective is created between "Printing" and "Hanako".

[0112] In the diffractive light-emitting moving image pattern (1) utilizing the moiré magnification phenomenon in the aforementioned first and second embodiments, when the image set as the base image (15) appears as the dynamic information (3), a plurality of base images (15) appear periodically at a certain interval. On the other hand, in the case of the IP image method diffractive light-emitting moving image pattern (1) of the present third embodiment, only one base image (15) appears as the dynamic information (3).

[0113] Next, the principle by which the aforementioned video effect is produced will be explained. With respect to the angle of the incident light, among the diffractive elements (7), the diffraction grating (8) that forms an angle orthogonal to the light diffracts the light particularly strongly, and only a part of the latent image element group (6) formed on the diffractive element group (4) where the light is strongly diffracted is sampled. Since the diffractive element group (4) has diffractive elements (7) arranged at a specific pitch (P1), when light is incident, the strip-shaped regions where strong diffracted light is generated will continuously occur on the diffractive element group (4) at the period of the specific pitch (P1).

[0114] As shown in Fig. 26, since the latent image element group (6) is configured with the same pitch (P1), the latent image element group (6) is sampled at the divided pitch (P1) when it is fabricated, and the base image (15) is reproduced in a form where the dividing process is played back in reverse. This base image (15) is visually recognized as the dynamic information (3) as it is. Also, by changing the angle of the incident light, the region that strongly diffracts the light in the phosphorescent element (7) changes, and by changing the sampling position of the superimposed latent image element group (6), the region where the compressed latent image element group (6) is reproduced also changes, resulting in a video effect on the dynamic information (3) of the base image (15).

[0115] The process of reproducing the above compressed image is the same as the process of reproducing the compressed image by a lenticular in integral photography, although the reproducing means of using light diffraction or light refraction for the reproduction of the compressed image is different. The above is the principle in the phosphorescent video pattern (1) of the third embodiment, where the dynamic information (3) is visualized, and by tilting the phosphorescent video pattern (1), a video effect is produced on the dynamic information (3). Also, the sense of depth and the sense of foreground that accompany the video effect are due to the fact that the dynamic information (3) moves in the horizontal direction, resulting in a sense of perspective caused by binocular parallax.

[0116] In the first and third embodiments using the linear phosphorescent element (7), the configuration of the phosphorescent element group (4) composed of straight lines has been described in both cases. However, the configuration of the phosphorescent element group (4) is not limited to straight lines. The phosphorescent element group (4) may be formed by a periodic combination of curved phosphorescent elements (7) as shown in Fig. 36, or may be formed by a periodic combination of concentric phosphorescent elements (7).

[0117] Also, when using linear luminescent elements (7), as shown in FIGS. 37(a) to 37(d), a luminescent element group (4) may be configured by combining linear or curved luminescent elements (7). In the forms of FIGS. 36 and 37, although the pitch and the drawing direction of the luminescent elements (7) vary respectively, according to the regularity of the luminescent element group (4), the latent image element group (6) is arranged correspondingly. Regarding the configuration of these luminescent element groups (4) and the constituent requirements and manufacturing methods of the corresponding latent image element groups (6), when using the curved luminescent elements (7) of FIG. 36, refer to Japanese Patent Publication No. 6032423. When using the configuration of FIG. 37 in which curved luminescent elements (7) and linear luminescent elements (7) are combined, the methods described in Japanese Patent Publication No. 6112357 and Japanese Patent Publication No. 64128576 may be used.

[0118] Furthermore, a luminescent element group (4) may be formed by combining linear luminescent elements (7) and dot-shaped luminescent elements (7). As an example of combining linear luminescent elements (7) and dot-shaped luminescent elements (7), by making the pitch in the first direction of the linear luminescent elements (7) and the dot-shaped luminescent elements (7) coincide, and applying a linear latent image element group (6) to the latent image element group (6), a luminescent moving image pattern (1) in which lines and dots are combined can be configured.

[0119] (Fourth Embodiment) Next, as the fourth embodiment of the present invention, a form will be described in which a luminescent element group (4) is formed by dot-shaped luminescent elements (7), and a moving image effect is expressed in dynamic information (3) by using a line configuration of the IP image method for the latent image element group (6). In the fourth embodiment of the present invention, the dynamic information (3) moves freely up, down, left, and right in the first direction (S1 direction) and the second direction (S2 direction) without being restricted in the moving direction of the movement in the first direction (S1 direction) as in the third embodiment.

[0120] In this fourth embodiment, as shown in FIG. 31, a character image, namely the Chinese character "Hanako", was selected as the so-called base image (15) to be presented as the dynamic information (3) on the luminous moving image pattern (1). This information of "Hanako" is assumed to be the name of the holder, and it is variable information that changes for each holder.

[0121] The structure of the luminous moving image pattern (1) of this fourth embodiment is shown in FIG. 32. The luminous moving image pattern (1) is composed of a luminous element group (4) and a variable image group (5). Since there is no unique information (2) in the luminous moving image pattern (1) of this fourth embodiment, the variable image group (5) directly becomes the latent image element group (6). In the fourth embodiment, this latent image element group (6) is composed of the Chinese character "Hanako" as the base image (15).

[0122] Next, with reference to FIG. 33, the configuration of the basic dot-like latent image element group (6) will be described. The latent image element group (6) is formed by arranging a plurality of latent image elements (11) obtained by dividing the base image (15) at a specific width and compressing it at a specific reduction ratio, with the same regularity as that of the luminous element group (4). This is the same as the configuration of the latent image element group (6) in the third embodiment.

[0123] However, different from the compression of the base image (15) in the third embodiment being only in the first direction (S1 direction), the compression of the base image (15) in this fourth embodiment extends in both the first direction (S1 direction) and the second direction (S2 direction). Also, the produced latent image elements (11) are arranged not only in the first direction (S1 direction) but also in the second direction (S2 direction).

[0124] As shown in FIG. 33, a frame (16) of a certain size is applied to a base image (15) representing the Chinese characters "Hanako", and only the image contained therein is divided and extracted. The divided image is compressed in a first direction (S1 direction) and a second direction (S2 direction) at a certain reduction ratio to form a single latent image element (11). Different from the case of the slit-shaped and long-extended latent image element (11) in the third embodiment, the latent image element (11) has a configuration in which a part of the base image (15) is simply reduced. Note that the example in FIG. 33 is an image in which the figure is deformed for clarity, and actually, the base image (15) is compressed to at least 20% or less.

[0125] Also, in the third embodiment, as a desirable form, a method of forming dynamic information (3) by mirror-inverting the latent image element (11) at an angle perpendicular to the first direction (S1 direction) and changing the direction of movement when it appears was described. Similarly, for the dot-shaped latent image element (11) in this fourth embodiment, a form using mirror inversion as a desirable form will be described. The latent image element (11) in FIG. 33 is formed by mirror-inverting the latent image element (11) about an angle (second direction (S2 direction)) perpendicular to the first direction (S1 direction). Thereby, it is possible to impart a characteristic of moving in a direction opposite (S1' direction) to the first direction (S1 direction) with respect to the dynamic information (3) generated from the latent image element group (6) composed of the latent image elements (11) that have not been mirror-inverted. However, the latent image element (11) may be formed without being mirror-inverted.

[0126] Furthermore, since the latent image elements (11) are dot-shaped, in addition to the angle (second direction) perpendicular to the first direction, the latent image elements (11) may be mirror-inverted about the angle (first direction (S1 direction)) perpendicular to the second direction. In this case, it is possible to impart a characteristic of moving in a direction (S2' direction) opposite to the second direction (S2 direction) to the dynamic information (3) generated from the group of latent image elements (6) composed of the latent image elements (11) that have not been mirror-inverted about the angle (first direction (S1 direction)) perpendicular to the second direction (S2 direction). As described above, the movement in the first direction (S1 direction) and the second direction (S2 direction) can be controlled by whether or not the latent image elements (11) are mirror-inverted in the first direction (S1 direction) and the second direction (S2 direction).

[0127] After producing one latent image element (11) by the above procedure, subsequently, the frame (16) is moved by a specific pitch (P1) in the first direction (S1 direction), only the image contained within the moved frame (16) is divided and extracted, and the divided image is compressed in the first direction (S1 direction) and the second direction (S2 direction) at a certain reduction ratio to form adjacent latent image elements (11), which are arranged shifted by a specific pitch (P1) in the first direction (S1 direction) next to the previous latent image element (11).

[0128] As described above, the frame (16) is moved to divide and compress the base image (15) to create and arrange the latent image elements (11). This is repeated. When the base image (15) is no longer contained within the moved frame (16), a row of the group of latent image elements (6) is completed. Subsequently, the frame (16) is moved by a specific pitch (P1) in the second direction (S2 direction), only the image contained within the moved frame (16) is divided and extracted, and the divided image is compressed in the first direction (S1 direction) and the second direction (S2 direction) at a certain reduction ratio to form adjacent latent image elements (11), which are arranged shifted by a specific pitch (P1) in the second direction (S2 direction) next to the previous latent image element (11). This is repeated to create the group of latent image elements (6). By repeating this procedure, finally, the dot-shaped group of latent image elements (6) is completed.

[0129] The description of the laws regarding the size and reduction ratio of the frame (16), the advantages and problems arising from changing their numerical values, and the advantages of the form using the moiré magnification phenomenon are basically the same as those of the third embodiment, and thus will be omitted.

[0130] Next, an ideal overlapping configuration of the luminescent element group (4) and the latent image element group (6) is shown in FIG. 34. As shown in FIG. 34, there is no deviation in the positions of each luminescent element (7) and each latent image element (11). In this fourth embodiment, the centers of each latent image element (11) overlap with the centers of each luminescent element (7). Even when it is not possible to arrange the centers of each latent image element (11) to overlap with the centers of each luminescent element (7) and there is a deviation in their respective centers, the video effect itself is produced, and thus the effects of the present invention are achieved. However, since the width of the movement of the dynamic information (3) may become small or the movement may become discontinuous, it is desirable to draw the variable image group (5) so that there is no deviation in the positions of each luminescent element (7) and each latent image element (11) as shown in FIG. 34.

[0131] Also, in this fourth embodiment, when the variable image group (5) is drawn with a laser later, since it is difficult to adjust the positional relationship of the overlapping of the luminescent element group (4) and the latent image element group (6), similar to the third embodiment described above, it can be solved by using a special scanning line configuration. For the specific scanning line configuration and manufacturing method, the scanning line configuration of the latent image element group (6) in the case of dots described in Japanese Patent Application Laid-Open No. 2016-203459 may be applied to the latent image element group (6) of the present invention.

[0132] Next, the effects of the luminescent video pattern (1) of this fourth embodiment will be described with reference to FIG. 35. FIG. 35 shows the formation of the luminescent element group (4) by the luminescent elements (7) in FIG. 20(d), and the latent image element group (6) is used as the variable image group (5), and it is the effect when arranged such that the centers of each latent image element (11) overlap with the centers of each luminescent element (7) as shown in FIG. 34.

[0133] When the glittering video pattern (1) is observed in an environment where diffracted light is generated, dynamic information (3) representing the Chinese characters "Hanako" appears as shown in Fig. 35(a). By slightly tilting the glittering video pattern (1), the position of "Hanako", which is the dynamic information (3), changes as shown in Fig. 35(b). By further tilting the glittering video pattern (1), the position of "Hanako", which is the dynamic information (3), changes further as shown in Fig. 35(c). Different from the third embodiment, the position changes in both the first direction (S1 direction) and the second direction (S2 direction). Also, the Chinese characters of "Hanako" in the appeared dynamic information (3) are observed with a sense of depth such that they are relatively deeper than the screen surface of the glittering video pattern (1).

[0134] Incidentally, if the glittering element group (4) is formed using the glittering elements (7) shown in Figs. 19(a) to 19(d), two pieces of dynamic information (3) representing "Hanako" appear in a pair and move in opposite directions to each other. This is because when the glittering element group (4) is formed using the glittering elements (7) shown in Figs. 19(a) to 19(d), two bright spots are generated in the glittering element (7) with respect to incident light from one direction. Conversely, when the glittering element group (4) is formed using the glittering elements (7) shown in Figs. 20(a) to 20(d), only one bright spot is generated in the glittering element (7) with respect to incident light from one direction, so only one base image (15) is reproduced as the dynamic information (3).

[0135] Next, the principle by which the above-described video effect is produced will be explained. With respect to the angle of the incident light, the diffraction grating (8) in the glittering element (7) that forms an angle orthogonal to the light diffracts the light particularly strongly, and only a part of the latent image element group (6) formed on the glittering element group (4) that strongly diffracts the light is sampled. Since the glittering element group (4) has the glittering elements (7) arranged at a specific pitch (P1) in the first direction (S1 direction) and the second direction (S2 direction), when light is incident, the dot-like regions where strong diffracted light is generated are continuously generated on the glittering element group (4) at a period of the specific pitch (P1) in the first direction (S1 direction) and the second direction (S2 direction).

[0136] Here, since the latent image element group (6) is configured with the same pitch (P1) in the first direction (S1 direction) and the second direction (S2 direction), the latent image element group (6) is sampled at the division pitch (P1) when it is fabricated, and the division process is played back in reverse to reproduce the base image (15). This base image (15) is visually recognized as the dynamic information (3) as it is. Also, by changing the angle of the incident light, the region that strongly diffracts the light in the phosphorescent element (7) changes, and by changing the sampling position of the superimposed latent image element group (6), the position of the reproduced base image (15) changes, resulting in a video effect in the dynamic information (3).

[0137] In the process of reproducing the above-mentioned compressed image, although the playback means of using light diffraction or light refraction for reproducing the compressed image is different, in the IP image method, it is the same as the process in which the compressed image is reproduced by the microlens array. The above is the principle in the phosphorescent video pattern (1) in the fourth embodiment of the present invention, where the dynamic information (3) is visualized, and further, a video effect is produced in the dynamic information (3) by tilting the phosphorescent video pattern (1). The above is the description of the fourth embodiment of the present invention.

[0138] In the third and fourth embodiments, when the variable information that needs to change information for each sheet is used as the dynamic information (3), the latent image element group (6) in the variable image group (5) irradiated from the laser needs to be generated on demand each time laser drawing is performed. Since it is impossible to fabricate the latent image element group (6) manually in an instant, it is desirable to use the fabrication software for the latent image element group (6) for integral photography. This software may use the algorithm described in Japanese Patent No. 6418576. By using this software, the latent image element group (6) with a video effect imparted to the variable information can be generated in an instant.

[0139] (Diffraction grating) Next, the diffraction grating (8) in the present invention will be described. The density of the diffraction grating (8) engraved on the luminescent element (7) in the present invention is desirably 500 or more per mm, and desirably 1000 or more when emphasizing the expression of hue. Basically, it is desirable to form the diffraction grating at a density in the range of 500 or more and 2000 or less per mm.

[0140] When the diffraction grating (8) in the luminescent element (7) is configured with a density of 500 or more per mm of the diffraction grating (8), the dynamic information (3) produces an effect of moving while gradually changing to different hues such as blue, green, yellow, and red. When expressing colors by diffracted light using the diffraction grating (8), by providing 500 or more diffraction gratings (8) per mm, diffracted light of rainbow colors from purple to red is generated. As the number of diffraction gratings (8) per mm increases, the diffraction angle of the diffracted light expands, so the angular range in which the diffracted light can be seen changes.

[0141] Suppose that the diffraction angle of the primary diffracted light generated from the diffraction grating (8) with a density of 500 per mm is in an angular range of about 10 degrees. Then, the diffraction angle of the diffraction grating (8) with a density of 1000 expands to about 20 degrees, and the diffraction angle of the diffraction grating (8) with a density of 1500 expands to about 40 degrees. By utilizing this phenomenon, the hue of the diffracted light visible to the observer can be controlled. As an example, when observing from a specific angle where the primary diffracted light of the diffraction grating (8) with a density of 500 per mm appears red, the diffraction grating (8) with a density of 600 appears green, and the diffraction grating (8) with a density of 700 appears purple. As described above, by controlling the density of the diffraction grating (8), it is possible to select the hue of the diffracted light and enrich the colors in the luminescent moving image pattern (1).

[0142] (Application Example) An example of a layer structure assumed to be attached to a printed matter using the luminous moving image pattern (1) of the present invention is shown in FIG. 38. In this specification, regarding the luminous moving image pattern (1) of the invention, only the luminous element group (4) and the latent image element group (6) that are essential for the configuration have been specifically described. These relate only to the hologram forming layer (9) and the metal film (10) with the minimum configuration in the luminous moving image pattern (1). As a practical form, a transparent reflective layer (17) is provided to increase the luminance, a protective layer (18) is provided to increase the durability, and an adhesive anchor layer (19) and an adhesive layer (20) are provided to enable attachment to a substrate, which is within the scope of common sense application of the present invention.

[0143] FIGS. 39(a) to 39(c) show an example of a hologram including the luminous moving image pattern (1) of the present invention attached to an identity card (printed matter). In the example of FIG. 39(a), personal information (Roman name) (21) which is a name printed by printing or laser drawing and the luminous moving image pattern (1) are arranged on a card (23) with background printing such as a ground pattern. The luminous moving image pattern (1) has the configuration described in the first embodiment. The dynamic information (3) in the luminous moving image pattern (1) is a moiré pattern in the background, and the variable information is given as unique information (2). In this form, the luminous moving image pattern (1) can be produced only by replacing the unique information (2) for each card. The labor of image processing for producing the variable image group (5) is minimized, and the luminous moving image pattern (1) of the present invention can be utilized without using special software.

[0144] FIG. 39(b) shows an example in which personal information (Chinese name) is arranged as dynamic information (3) in the luminous moving image pattern (1) in a form that can be matched with a face image and personal information (21) which is a name printed by printing or laser drawing on a card (23) with background printing such as a ground pattern. The luminous moving image pattern (1) has the configuration described in the third embodiment, and the dynamic information (3) is variable information that needs to be replaced individually.

[0145] Fig. 39(c) shows a card (23) with an underlying print such as a background pattern, on which there is personal information (Romanized name) (21) printed by printing or laser drawing, and personal information (Chinese name) is arranged as dynamic information (3) in the luminous moving image pattern (1) in a form that can be matched with the printed personal information (Romanized name) (21). In addition, a face image and a personal number are given as unique information (2), and another luminous moving image pattern (1) with moiré arranged as dynamic information (3) in the background is arranged. In this example, the luminous moving image pattern (1) simultaneously has the configurations described in the first and third embodiments.

[0146] Furthermore, as shown in Fig. 40, by forming so as to straddle the personal information (Romanized name) (21), which is the name printed by printing or laser drawing, on a part of the luminous moving image pattern (1) and the background pattern of the card (23), it is possible to improve the resistance to the act of peeling off and falsifying the luminous moving image pattern (1).

[0147] (Example) Hereinafter, an example of manufacturing a specifically manufactured luminous moving image pattern (1) will be described in detail according to the form for implementing the above-described invention. Note that the present invention is not limited to this example.

[0148] An embodiment of the present invention will be described. As shown in FIG. 41, a card (23) with an underprint such as a ground pattern is provided with a group of luminescent elements (4) attached thereto in advance. In the first embodiment, the group of luminescent elements (4) has a configuration in which the linear luminescent elements (7) shown in FIG. 3 are arranged at a pitch of 0.3 mm. The luminescent element (7) has a structure filled with a diffraction grating (8) having the configuration shown in FIG. 5(b). The diffraction grating (8) is formed within an angular range of -45 degrees to +45 degrees. The base material of the card (23) is made of white polycarbonate as the base, and a laser coloring layer (22) is attached to the surface thereof at that time. The sheet constituting this layer has a function of coloring black when irradiated with a laser having a wavelength of 1 μm or less. By adopting such a layer structure including this, it becomes a desirable configuration for directly printing variable information on the card (23) with a laser. The transparent protective layer (24) is made of transparent polycarbonate. At this stage, this card (23) is a base card for everyone before personalization, on which no variable information (personal information) has been written.

[0149] As shown in FIG. 42, a variable image group (5) was imparted to the card (23) to which this group of luminescent elements (4) was attached, using a laser irradiation device (12). The variable image group (5) includes a latent image element group (6) having the Chinese characters "Print Hanako" shown in FIG. 26 in a scan line configuration of the IP image method. The arrangement pitch of the latent image elements (11) constituting the latent image element group (6) is 0.3 mm, the same as that of the group of luminescent elements (4).

[0150] A YVO4 laser marker (manufactured by Keyence) was used as the laser irradiation device. The wavelength of the laser irradiated from this device is about 1 μm, which is a wavelength suitable for removing the metal film (10) of the group of luminescent elements (4) and losing the luminescence. The variable image group (5) was irradiated with a laser as a processed image at a laser power of 15%, a scan speed of 200 mm / s, and a Q-switch frequency of 100 kHz. At the same time, the face image (21) of the holder and the Roman name "Hanako Insatsu" (21) were printed on the laser coloring layer (22) at the same time.

[0151] As a result, a card (23) with a hologram (luminous video pattern (1)) personalized for each cardholder as shown in Fig. 43 was completed. In the card (23) produced in this embodiment, the face image of the cardholder and the name (21) in Roman letters are directly printed on the laser color-developing layer (22) of the card (23), and are visualized in black by the function of the laser color-developing layer (22). In the luminous video pattern (1), the name of "Yinshua Huazi" in Chinese characters is given as dynamic information (3) as information paired with the personal information (21) consisting of the name in Roman letters. It was confirmed that by changing the angle, the characters "Yinshua" and "Huazi" move separately in the left-right reverse direction. In the embodiment, the transparent protective layer was attached to the card surface before processing. However, when there is a problem such as swelling caused by laser processing, it is also possible to apply a form in which laser irradiation is performed first and then the transparent protective layer is attached.

[0152] In this embodiment, an example was described in which a variable image group (5) is drawn with a laser on a base card for everyone before personalization for personalization, but it is not limited to this. For example, the luminous element group (4) of the present invention is pre-attached to a data page on which the personal information of a passport booklet (passport) holder is described, and a base booklet that is almost completed by printing and booklet binding and only personal information is not input is pre-manufactured and stocked. When a request for passport issuance is received from a national applicant, a latent image element group (6) with a video effect added to the individual information such as the face image and name of each applicant is generated to generate a variable image group (5). Then, in the final passport issuance process, the data page of the base booklet is opened, and the variable image group (5) is drawn on the luminous element group (4) there with a laser. Through the above procedure, it is possible to efficiently provide the applicant with a passport booklet with a hologram having a video effect and personalized for each user.
