Description of the Invention: [Technical Field] The present invention relates to an image processing inspection system for printing media using a special functional ink such as pearl ink, a true and false identification method for a printing medium, and Its suitable photographic device. [Prior Art] Since the first time, in order to identify the authenticity of print media such as securities, lottery tickets, merchandise coupons, etc., a part of the color variable printing layer formed by pearl ink or the like has been proposed. A technique in which specific information is patterned and concealed (for example, refer to Patent Document 1). Further, there has been proposed a technique of printing a mark for authenticity determination using ink or the like which emits fluorescence by ultraviolet rays or infrared rays on a color-variable printing layer (for example, see "Patent Document 2"). Further, there has been proposed a technique of superimposing and printing other marks for authenticity determination using inks that do not absorb infrared rays on a mark for authenticity determination using an infrared absorbing ink (for example, refer to Patent Document 3). As the color variable printing layer, in addition to the pearlescent ink described above, a metal ink such as an pt VI (Optically Variable Inks) ink, a Cholesteric liquid crystal ink, a gold ink or a silver ink may be used. Special function inks such as ink). However, some printed patterns using special function inks are printed by light reflection and interference, etc., which can be seen only when viewed from a specific direction, and can be observed from other specific directions. See different patterns. Further, for example, when the illumination is performed in a direction substantially perpendicular to the brush surface of the printing film, the pattern is increased, and any pattern is hardly observed. Therefore, when the positional relationship between the light source and the photographic element is fixed, the first photographic device _printing _ series may not be able to capture the original photographic case', so that it is not easy to perform true and false detection by image processing inspection. In the case of using the infrared absorbing ink or the externally reflective ink on the color variable printing layer to print the true false (four) mark, the same is true for the second ray: 红外线 红外线 Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ The infra-red reflective ink of the consumer may not be able to capture the mark for authenticity determination of the drawing. Tobacco and other techniques are not limited to the above-mentioned valuable documents, and the need for quality in medicine or fragrance is two. That is, it is necessary to identify the package of the goods, which is different from the cost, and is costly. In addition, the periodical processing and inspection system performs true and false determinations. /... At the site where the product is used, it is easy [PRIOR ART DOCUMENT] Patent Document 1: Patent Document 2: Patent Document 3: [Disclosure] Japanese Patent Laid-Open No. 2000-6564 Japanese Patent Correction 8.1 Help No. 3 [Problems to be Solved by the Invention] The issue of the above-mentioned previous example was issued to provide the 201216208 39025pif-type to be able to perform at a lower cost and at a lower cost. The image processing and inspection system for the identification of printed materials, the authenticity of the printed media, and the suitable imaging device. [Means for Solving the Problem] The image of the printing medium according to the first embodiment of the present invention includes a real printing medium having a first ink printed on the surface by an infrared ray pigment and a color variable pigment. a second pattern printed by the second infrared pigment and the second ink of the color variable pigment; and the photographing device is a predetermined use of visible light and infrared light (10) to identify the surface of the printing medium of the target The pattern printed in the area; and the true and false judgment of the farm, it is better to use the image data outputted from the above-mentioned photographing device to determine whether the printed object of the identification object is a real printing ship; and in the state of shielding the infrared light The surface/surface of the print medium to be identified is changed in the visible light direction, and the illumination angle of the visible light is changed, and the plurality of first images on the surface of the target medium are identified, and the medium to be identified is printed in the state of shielding visible light. The surface of the infrared light, in terms of changing the illumination angle of the above-mentioned infrared light, on the one hand, the identification of the object of the printed body _ a plurality of f 2 f For example, the image data of the above-mentioned plurality of second image data cutters I and the related data of the second pattern are compared with each other in the above-mentioned plurality of second image data sheets. Corresponding to the first pattern of the above-mentioned first pattern and the second pattern of the second pattern, the first pattern is not included in the first pattern, and the second pattern is related to the second pattern. When the data is included, it may be included in the above-mentioned information. In the image processing inspection system in which the above-mentioned cone-shaped object is printed on the print medium, it is preferable that the above-mentioned second pattern is missing. Straight ------ like data again == Jing set change threshold 'for the second shadow, preferably the above color variable pigment is pearlescent pigment. The true and false identification method of the printing (fourth) body of the second embodiment is to print the first pattern on the surface of the medium by the first ink containing the infrared absorbing pigment and having the reflection two, and by including 2 and color The second ink of the variable pigment is used to print the first and the infrared light, and the visible light is irradiated onto the surface, and the surface of the printing medium is photographed on the one hand. In the visible light state, the surface of the object is irradiated with infrared light, and the plurality of second images of the surface of the printing medium to be identified are imaged by the above-mentioned infrared light. The first image and the second pattern are included in any one of the plurality of second images, and the first pattern is not included in the plurality of second images, and the second pattern is included In any of the second images, the related information of the second pattern is missing, and 201216208 39025pif := two =: when the data is used, the above-mentioned authentication target print medium is broken and the above-mentioned true and false judgment 2 image data is doubled. Chemical. The image data obtained by the camcorder device also calls the button limit value, and the printing medium for the second shadow object is 'two fixed: the square of the reference=::;: brush=the surface is perpendicular to the surface and the above-mentioned identification object is printed. The surface of the medium ====== the respective angles of the plurality of illumination angles, and the surface of the medium is determined by the infrared ray: a plurality of = and a plurality of the first _ The illumination device includes a plurality of LED arrays in which a plurality of 201216208 39025pif LEDs (light-emitting diodes) are arranged in a ring shape, and a plurality of rows of light guides arranged in a concentric manner. The front end portion of the light guide is formed with a reflecting surface formed by a plurality of inclined surfaces, and the rear end surfaces of the light guides are opposed to the plurality of LED arrays arranged in a ring shape. Further, it is preferable that the light-shielding body is in close contact with the surface of the printing medium to be identified (four), and the light-removing lens is further provided, and the front end of the light-shielding cylinder is in contact with the identification target print medium. In the state, the surface of the above-mentioned genus of the above-mentioned genus is the object-side focal position of the lens, and the photographic element becomes the focal position on the image side. [Effects of the Invention] The first pattern is printed by using the ith ink containing a pigment that absorbs the red scorpion line and the color variable pigment. Therefore, if the visible light is used as the field light, the first pattern is printed. When the light is changed by the color, the infrared light is used as the illumination light by the i-th ink, and the infrared light is absorbed in the printing of the f-second two, and the infrared rays from the part are not. The amount of light will decrease, making it darker (black) than the surrounding. The second pattern on the other side is a pigment containing reflected infrared rays and a color '=printed by ^. Therefore, if visible light is irradiated as illumination light Si, the pattern drawn using the second ink is taken as a line of light. The illuminating ink is reflected, so that the amount of light reflected is greater than that from the worker: the second line will reflect the amount of light 'so it is brighter than the surrounding (white). Because the second image data obtained by the photographing device is binarized by the threshold value of 11 201216208 39025pif, the first image data can be made first by the setting of the threshold value. The relevant information of the pattern is missing and the relevant information of the second pattern is left. Conversely, the related data of the second pattern in the second video material may be missing, and the related material of the first pattern may remain. Further, the second image data may be subjected to multiple binarization processing by changing the threshold value. True and false identification can be achieved by properly implementing the processes. The objects and features of the present invention will be clarified by the description of the preferred embodiments set forth below. [Embodiment] Hereinafter, embodiments of the present invention will be described in more detail with reference to the accompanying drawings which form a part of this specification. The same or similar portions in the entire drawings are denoted by the same reference numerals, and the repeated description thereof will be omitted. (First embodiment) The image processing system of the printing medium according to the first embodiment of the present invention and the method of authenticating the printing. W丨 is a diagram showing an image processing inspection system applicable to the authenticity of the (4) material printed matter, such as securities, lottery tickets, and merchandise coupons. Further, _ 3Α scans the surface of the print medium 2 in the image processing inspection apparatus 1 in the image processing inspection system:: case = true table, : the shadow of the surface of the printing medium 2 of the authentication object; advance: two = 12 201216208 39025pif 3, and the true and false judgment of the true and false judgment of the print medium 2 which is photographed by the m彡 device 3 as shown in Fig. 2, in the print medium, each shot is rubbed, i look (w mountain On the surface, the ink with the absorption or reflection visible is printed, and the trademark 21, the number 2, the barcode 25, the predetermined position of the medium 2 (for example, the middle 2) are printed. ^ Again, in the printing θ r open 4 special), set the watermark 26. Second, in the other predetermined positions of the printing Cong 2 (4) such as riding materials, = color inks such as light ink and printed with authentic identification The true and false identification of the pattern (4) _ 27 is based on the use of different pigment components ==, and can be constructed according to the angle of observation or the illumination angle of the illumination light: different patterns are observed. More specifically, the second ink having the infrared ray-absorbing iridescent ink and the infrared-reflecting pigment and the color-changing pigment is printed with the predetermined first pattern by the H-th ink. 27a, and printed by the second oil: there is a predetermined second pattern 27b different from the first figure f27a. The pigment absorbing red 2 and the pigment reflecting infrared rays are invisible (so-called colorless and transparent). The color of S is the same as the color of the surface of the above-mentioned printing medium (the color of the paper, etc.), and is selected so that it cannot be directly recognized by the naked eye. The position, size, and specific content of the first pattern 27a and the pattern 27b are not particularly limited, and may be an identification code such as a one-dimensional barcode or a two-dimensional barcode, or may be an identification number such as a pattern number. ° When the print medium 2 to be identified is entangled inside the image processing inspection apparatus 1, the image 4 inspection apparatus 1 irradiates the surface of the printing medium 2 13 201216208 39025pif with visible light and infrared light, and by CCD ( A photographing element such as a charge Cmipled Device or an electric coupling element reads the first pattern 27a and the second pattern 27b on the surface of the photographing medium 2. Since the first ink and the second ink reflect visible light, respectively, the first image 27a and the second pattern 27b are included in the image captured by the imaging element, and the first pattern 27a and the second pattern 27b are included in the image data. Related information. However, the color-variable pigment is caused by interference or the like, and the color is changed by the angle of observation, or a specific pattern can be observed or not observed. The pearl pigment as an example of the color variable pigment is a translucent film comprising a plurality of transparent films formed by coating a metal oxide having a refractive index souther than the surface of the substrate on a surface of a substrate such as mica, SiO 2 or A1203. The platy pigment. The light reflected on the surface of the metal oxide layer is transmitted through the metal oxide layer, and the light reflected on the surface of the substrate is transmitted through the substrate, and the light reflected at the interface between the substrate and the other metal oxide layer interferes. Light of a specific wavelength is mutually enhanced, and light of other specific wavelengths cancel each other 'by thereby exhibiting, for example, pearl-like luster. Further, the pearlescent pigment is layered in the ink. Therefore, it has a property of reflecting incident light according to Snell's law. Therefore, depending on the refractive index and film thickness of the substrate or the metal oxide, the wavelength of the incident ray, and the incident angle, the light incident from a specific angle is reflected in a state where the intensity is enhanced by the interference, and is incident on the imaging element. And if the intensity of the light incident on the imaging element is too strong compared to the predetermined threshold value, the charge accumulated in the pixels of the imaging element may overflow, and the 201216208 39025pif may not be regenerated or may be obtained. Image processing image data. As shown in Fig. 3A, the casing u of the image processing inspection apparatus i has a closed structure with external light and also serves as a photographing m. Inside the casing 11, a illuminating device 12 constituting a plurality of LED arrays 12a and 12b of the photographing device 3, a lens array 13, a linear CCD, and the like are provided, and the printing medium 2 is introduced into the casing. u's internal roller 15, monitor device 16, including cj^central processing unit, central processing unit) #&R〇M (Read〇nly memory, only buy hidden body) and RAM (Random- The authenticity judging device 4 such as a memory such as an access memory or a random access memory (details will be described later). In the memory of the authenticity judging device 4, the volatile memory such as ram is temporarily stored as image data output from the imaging device 14, and also serves as a part of the photographing device 3. The illuminating device 12 includes a plurality of sets, for example, the above-described two sets of LED arrays 12a and 12b, so that the irradiation angle (incident angle toward the surface of the printing medium 2) of the illumination light irradiated on the surface of the printing medium 2 can be switched. Further, each of the LED arrays 12a and 12b includes two kinds of light sources of a visible light LED for illuminating visible light and an infrared light LED for illuminating infrared light. Furthermore, the two visible light LEDs and the infrared light LEDs may be alternately arranged in a row, or the same kind of LEDs may be arranged in two rows with each other. In the first embodiment, two sets of LED arrays 12a and 12b are provided. Therefore, for example, the irradiation angle of one of the LED arrays 12a (the incident angle toward the surface of the printing medium 2) is set to 6 degrees, and the other LED array 12b is used. The illumination angle is set to 30 degrees. However, the number of LED arrays and the illumination angle 15 201216208 39025 pif degrees are exemplified, and are not limited thereto. Three or more LED arrays may be provided.

It is not necessary to discharge the entire printing medium 2 to the housing portion as long as the distance required for reading the image is reversed. Further, when three or more sets of LED P vehicles are received, or when the irradiation angle of the i group of LED arrays is changed by three or more stages, the operation may be performed based on the above-described operations. Further, after the LED arrays 12a and/or ^ = are illuminated, the LED arrays 12a and 12b are simultaneously illuminated, and three of the first image data and the second image data are respectively obtained. For example, after the visible light of the LED array 12a is illuminated and imaged, the visible light of the arrays i2a and 12b is simultaneously illuminated to be imaged, or the infrared light of the LED array 12b is illuminated to be imaged, and the infrared light of the arrays 12a and 12b is simultaneously After the light is emitted and the visible light of the LED arrays 12a and 12b is simultaneously illuminated, the infrared light of the LED arrays 12a and 12b is simultaneously illuminated to perform imaging. 17 201216208 39025pif The authenticity judging device 4 includes a CPU that performs pattern matching, a ROM that stores a pattern matching program or related information of the first pattern and the second pattern, and a video material that is temporarily recorded by the photographing device 3, and the like. RAM, etc. Each of the first pattern 27a and the second pattern 27b is printed using a first ink containing an infrared ray-absorbing pigment and a color-variable pigment, and a second ink containing a pigment that reflects infrared rays and a color-variable pigment. Therefore, depending on the illumination angle of the illumination light, image processing of the obtained image data may not be performed. In the present embodiment, a plurality of images are captured by changing the type of illumination light and the illumination angle of the illumination light, and the authenticity determination device 4 sets a plurality of numbers! The image data and the plurality of second image data are compared with the related data of the first pattern and the related data of the second pattern. Further, when any one of the plurality of first video materials includes the related material of the second pattern and the related material of the second pattern, and the related material of the first pattern is absent in any of the plurality of second image data When the related material of the second pattern is included or the related material of the first pattern is missing from any of the plurality of second image data, the print medium 2 to be identified is determined to be genuine. Print media. The first pattern 27a is printed by using the first ink containing the infrared absorbing pigment and the color variable pigment. Therefore, when the visible light is irradiated as the illumination light, the visible light is reflected by the color variable pigment, thereby using the t ink. The pattern depicted is taken. If Zhao ^ ^ ^ ^ and 咁 C black). On the other hand, the second pattern 27b 201216208 39025pif is printed using a second ink containing a pigment that reflects infrared rays and a color, so that if the light is used for the Japanese silk, the image is drawn using the second ink. 1. When the illumination __ is used as the illumination light, the infrared ray is reflected in the portion where the second pattern 27b is printed, and the reflected light ray is reflected from the red light reflection of the other portion, so that it is more reflective than the surroundings. Bright (4). Therefore, if the second video data obtained by the imaging device 3 is binarized by the predetermined threshold value, the first pattern of the second video material can be set by the setting of the threshold value. The related information is missing, and the related information of the second pattern is left. On the contrary, the related information of the second pattern in the second video data may be missing and the related information of the first pattern may be left. In addition, the second image data may be subjected to multiple binarization processing by changing the threshold value, and the true and false identification may be realized by appropriately implementing the processing. When the contents of the f 1 pattern 27a and the second pattern 27b are predetermined patterns, symbols, or the like, and can be easily confirmed by the operator's visual observation, the imaging device 3 captures (4) the image data is directly scanned from the iU to the monitor. Armored ^ 16. The table (4) of the printing ship 2, which is the first to receive the visible light, is imaged on the face of the monitor device 16 as the first image. Next, an image of the surface of the printed body 2 obtained by the external light is spread on the top surface of the monitor 2 to be the second image. When the upper portion of the monitor device 16 is displayed as the first image, the first pattern 27a and the second pattern 2 are displayed; and further, when only the first pattern 27a or only the second pattern 27b is displayed as the second image, or when When the threshold value is changed and the multi-value processing is performed, the first pattern 27a and the second pattern 2713 are displayed. The operator can judge the print medium as genuine, and if it is not, the product is judged to be a defective product. The content of the #1st pattern W and the 2nd pattern 27b is not easily identifiable by the operator's visual inspection, and the image data captured by the camera 2 is input to the true and false judgment. Device 4, predetermined image processing. As a result of image processing such as pattern matching, among the 97 first image data, there is a related material of the first pattern L 2 2 帛 27b, and a plurality of second images 9 Γ々 7 读 are read. When there is only the first pattern 27a or only the second pattern, or when both the first pattern 27a and the second pattern 27b are present, the authenticity 4 determines that the print medium 2 is genuine, and when it is not the case, it is broken. Layer product. When it is judged to be defective, the warning is issued to the author by displaying a predetermined warning on the = of the monitor device 16 and/or turning on or off the sound of the sound. (Second Embodiment) Next, an image processing inspection system of a printing medium according to a second embodiment of the present invention and a method for authenticating the printing medium will be described.

In the aging towel, the hand-type imaging device 6 constituting the image processing inspection device 1 is brought into contact with the surface of the three-dimensional printing medium 5, and the image on the surface of the printing medium 5 is imaged and read in the printing. The prescribing (4) on the surface of the medium 5 is used for authenticity identification. ^ "Printing medium 5 is a three-dimensional printing 20 such as a carton, 201216208 39025pif medium, on the surface of the printing medium, using ink that absorbs or reflects visible light, and has a trade name, a trademark, a company name, The identification mark, the amount, etc. are not shown, and the bar code 51 or the like which symbolizes the information. In the printing of such commercials, identification marks, etc., in addition to the special light ink, metal oil such as gold ink or silver ink is used: These metal inks contain metal powder as a pigment, have a high reflectance, and have a property of reflecting incident light according to Snell's law. Therefore, depending on the imaging element, the illumination angle of the illumination light, and the amount of light of the print pattern formed by the metallic ink to the imaging element, the amount of light from the imaging element is reduced, and sometimes the image may not overflow. Obtain image data of renewable ^ 3 / Fan Li. Therefore, in the second embodiment, the photographing is performed so that the irradiation angle of the illumination light can be changed. The size of the three-dimensional printing medium 5 such as the Tianshangkou package is also limited by the weight of the contents of the P-brushing medium 5. Therefore, at least the photographing device 6 can be selected as the image processing inspection device 1, and the photographing device 6 is constructed/held. Therefore, the special type 16 and the true and false apparatus shown in FIG. 4 are different from each other.

LED array 21 201216208 39025pif Columns 63 and 64 are disposed around the photographic lens 61. For example, a plurality of LEDs are arranged in a ring shape in a plurality of rows (for example, two rows). The LED arrays 63 and 64 respectively include visible light for illuminating visible light. LEDs and two kinds of light sources for illuminating the infrared LEDs of the infrared 1. The two types of LEDs are alternately arranged, for example. The light-shielding tube 68 includes a protective cover 67 that abuts the identification object printed ship 5 that is true or false. The surface or at least a part of the surface of the identification target printing medium 5 is covered to shield visible light and infrared light. The light guides 65 and 66 are formed of, for example, a translucent resin such as acrylic, and are arranged in a plurality of concentric circles. (For example, in two rows, the outer peripheral surface of the light guide 65 disposed on the inner side is coated with a light-shielding paint. Further, it is also provided with a light-shielding (light-shielding) 68, and is shielded by a light-shielding paint. Disposed on the outside The outer peripheral surface of the light pipe 66 is coated.

Further, the light guides 65 and 66 are provided. The length is set such that the light reflected on the reflecting surfaces 65a and 66a irradiates the subject region having a predetermined diameter with a certain brightness or more. The object side and the image side of the photographing lens 61 are provided. The focal length is set in such a manner that the surface of the printing medium 5 becomes the object-side focus position of the photographing lens 61 in a state where the protective cover 67 attached to the end of the light-shielding tube 68 22 201216208 39025pif is in contact with the printing medium 5 . And like The focus is on the surface of the photographic element 62. The light output from the LED array 63 or 64 is linearly advanced inside the light pipe 65 or 66, or - in terms of repeated reflection at the interface of the tube 65 or 66 with the air... The inside of the tube 65 or 66 travels and is reflected by the reflecting surface 65a or 66a and then emitted from the light guide 65 or 66 to be incident on the surface of the printing medium 5. On the surface of the printing medium 5, except for the incidence having the above predetermined In addition to the illumination light of the incident angle, illumination light having an incident angle other than this is incident, but the directivity of the output light from the LED is high. Therefore, the illumination light having the predetermined person (4) is dominant. The LED array 63 or 64 is capable of illuminating visible light and infrared light on the surface of a plurality of county shards (4) bodies which are different from the vertical. When the child-held imaging device 6 is brought into contact with the surface of the printing medium 5, and the second and second patterns printed on the surface of the printing medium 5 are read for authenticity identification, one of the LED arrays is made. The phantom visible light LED emits light and is photographed by the photographic element & and the infrared light LED of the LED array 63 is illuminated to be photographed by the photographic element 62: secondly, the visible light LED of the other LED array 64 is made The illuminating strip is photographed by the photographic element 62, and the infrared SLED of the led array 64 is caused to illuminate the squeaking element 62 to ride the photograph. In this way, the four copper images are successively performed, and the first image data and the second image data are respectively called. The switching and shooting of the illumination light is short. 23 201216208 39025pif Advance 'But for more accurate shooting, it is preferable to output a sound signal, etc. after the shooting. In other words, it is preferable for the user to continuously contact the photographing device on the surface of the printing medium 5 until the sound signal is output to the first image data and the second image data in the two-way true/false judging device 4. Since the case of the first embodiment is the same, the description thereof will be omitted. Further, the second embodiment is not limited to printing on the above-described product package or its film (outer package)! The pattern and the second pattern can also be applied to the surface of the inner packaging material such as ρτρ (ρ^ugh package blister package) in which the tablets or capsules are individually packaged. For example, in a pharmacy of a medical institution or the like, when the medicine is supplied according to the square f, the image processing inspection secret can be used to identify whether the printed surface of the back product of the genuine product or the fake product has a metallic luster, and therefore includes the above. The photographing device 6 of the illumination device described above is effective. Further, the angles of the reflecting surfaces 65a and 6 constituting the light guides 65 and 66, for example, need not be fixed values, and may be changed little by little in order. As shown in the figure, the configuration may be such that the light guide 65 having the reflection (four) a is not included, and the LED array 63 is irradiated to the surface of the printing medium $ from the straight surface, and the LED array 64 is applied to the printing medium 5. The surface is irradiated at a different angle from the vertical. The order of light emission of the coffee grids 63 and 64 is not particularly limited, and the visible light coffee can be made to emit light, and then the infrared light LED _ emits light, and the order is reversed. The LED array 63 and/or the single-light=light-emitting LED array 63*64 can also be simultaneously illuminated to obtain three of the first image data and the second image data. 24 201216208 39025pif The preferred embodiment of the present invention has been obtained. The present invention is not limited to the specific embodiments, and various changes and modifications may be made without departing from the scope of the appended claims.
