  Each of the above-described conventional techniques provides various types of information by enabling easy connection to a URL expressed by a two-dimensional barcode consisting of a black and white pattern. However, since it is only connected to the URL represented by the two-dimensional barcode itself, for example, it is not possible to cope with the case of switching to another URL. In addition, 2D barcodes are not easy to recognize with low-resolution cameras, (2) difficult to read from an oblique angle and have a low recording range, and (3) need to read close-up images. Have Furthermore, the two-dimensional barcode needs to be printed with high quality, and there is a disadvantage that the display size is limited.

  The present invention can be read even with a low-resolution camera, can be read easily without considering the focus, reading angle, need for close-up scanning, etc. Further, high-quality printing is not required and the display size is limited Another object of the present invention is to provide a technology that can provide information to a customer with a reusable URL using a loose code.

  In order to achieve the above object, the invention according to claim 1 is a barcode capable of obtaining code information by decoding an image obtained by photographing with a portable terminal device with a camera, and a plurality of data A recipe information providing system using a color code, which is a barcode in which code information is embedded by displaying a plurality of colors in each cell, and includes a portable terminal device with a camera, an intermediate server, and a recipe server, A portable terminal device with a camera, a means for photographing a color code displayed corresponding to a food material that is a product, a means for decoding a photographed color code image to obtain a color code number, and the color code Based on the means for transferring the number to the intermediate server and the URL returned from the intermediate server, access to the recipe server is required. And a means for displaying dish information and / or recipe information provided from the recipe server, and the intermediate server stores a color code number database storing URLs corresponding to the respective color code numbers; Means for obtaining a URL corresponding to the color code number transferred from the camera-equipped portable terminal device from the color code number database and returning it to the camera-equipped portable terminal device, wherein the recipe server comprises the In accordance with an access request from the camera-equipped portable terminal device, there is provided means for transmitting cooking information and / or recipe information corresponding to the photographed color code to the camera-equipped portable terminal device.

  The invention according to claim 2 is the recipe information providing system according to claim 1, wherein the portable terminal device with a camera sends a transmission request for an email including the displayed dish information and / or recipe information to the recipe server. The recipe server includes means for transmitting a mail including the requested dish information and / or recipe information to the camera-equipped portable terminal device in response to the mail transmission request. It is characterized by.

  According to the present invention, by using a color code, it can be read by a low-resolution camera, and can be easily read without considering the focus, reading angle, close-up reading need, etc. It is possible to provide recipe information with a reusable URL to the customer by using a code that does not require printing and has a loose display size limit. This has the merit of helping to promote sales of ingredients used in the recipe.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 shows an overall configuration of a recipe information providing system according to the present invention. A color code 102 is printed in the vicinity of an ingredient for which recipe information in the food advertisement 101 distributed to the user is to be provided in advance. The color code will be described in detail later. The user photographs the color code 102 with the camera of the camera-equipped mobile phone 103. The camera-equipped mobile phone 103 decodes the image of the color code 102 acquired by photographing, and acquires the color code number indicated by the color code 102. Further, the mobile phone 103 transfers the color code number read by the mobile phone 103 to a predetermined intermediate server 104. In short, this transfer is processing for issuing a request including a color code number as a parameter and accessing a predetermined URL of the intermediate server 104. The intermediate server 104 transfers a URL including the product ID corresponding to the color code number as a parameter to the mobile phone 103.

  The mobile phone 103 automatically accesses a URL including the product ID as a parameter. The URL is an address indicating the recipe server 105, and is an address indicating a page on which the dish information of the product specified by the product ID is described. By accessing this URL, cooking information of the product is displayed on the mobile phone 103. The displayed dish information includes a list of various dishes using the product (foodstuff). When the user selects an arbitrary dish from the displayed dish list, the user accesses the recipe server 105 again, and detailed recipe information of the selected dish is displayed on the mobile phone 103.

  FIG. 2 shows a display example on the mobile phone 103. FIG. 2A shows a photographing result on the display 200 when a color code is photographed by the camera of the mobile phone 103. In 201, a photographed color code is displayed. The access to the intermediate server 104 from the screen of FIG. 2A may be automatically performed after shooting, or the URL of the intermediate server 104 is displayed on the lower side of the color code 201 on the screen 200 to display the user. The intermediate server 104 may be accessed by clicking the button.

  FIG. 2B is an example in which a dish information page acquired by accessing the URL (recipe server 105) transmitted from the intermediate server 104 is displayed on the screen 200 of the mobile phone 103. Reference numeral 211 denotes a display of a photograph or the like of food that is a product corresponding to the color code number. 212 is a list of dishes using the ingredients. When the user selects one from the menu 212, a recipe information page of the dish in the recipe server 105 is displayed. FIG. 2C is a display example of such recipe information. Below the photo 213 such as the completion of the dish, the ingredient list 213 of the dish is displayed, and further how to make the dish 215 is displayed (if the display information does not fit in the screen, it can be displayed by scrolling). . The ingredients list 214 allows the user to know what ingredients and how much to purchase to make the dish. Therefore, from the standpoint of the dealer, there is an advantage that it leads to sales promotion of materials other than the main food.

  FIG. 2D shows a state in which the mail transmission instruction 216 is displayed at the bottom of the screen by scrolling from the screen of FIG. When the user selects this mail transmission 216, the recipe information is mailed to the mobile phone 103. Since the received mail can be referred to at any time, the user can refer to the purchase list and the recipe.

  The configuration of the color code will be described with reference to FIG. FIG. 3A shows an example of a color code cell configuration. The color code is composed of a predetermined number of vertical and horizontal blocks. FIG. 3A shows a 5 × 5 block configuration. One block is called a cell. 3A, 4 × 4 cells D11 to D44 in the upper left are data cells, P1r to P4r are parity data of each row, and P1c to P4c are parity data of each column. Prc is a position cell for detecting the position of the color code. Each data cell takes one of four colors, for example, red, green, blue, or black. As a result, about 17.1 billion patterns (4 to the 17th power) can be expressed by 4 × 4 data cells and position cells. Further enlargement is possible by increasing the number of cells. The color code is physically formed on the surface and is therefore two-dimensional, but is not a so-called two-dimensional code (for example, QR code (registered trademark)). This is because one cell takes any one of a plurality of colors, so there is a dimension in the color direction. The color code is described in, for example, Japanese Patent No. 3336311.

  FIG. 3B shows a printing example of a 5 × 5 color code. In the figure, each cell portion is represented by a fill pattern such as diagonal lines, but as described above, in an actual color code, each cell takes one of four colors, for example, red, green, blue, and black. FIG. 3C shows an example of a 5 × 8 block color code. The combination of colors to be used and the size of the color code on the printed matter are arbitrary. However, it is necessary that the size be within a range of about several mm on the screen to fit within the screen when taken with a camera-equipped mobile phone.

  The color code can be read, for example, by a minimum 3 mm × 3 mm code regardless of the amount of content information. Further, since color recognition is not detailed shape recognition as in a two-dimensional code, the recognition rate is high without depending on camera performance and print quality. It can be recognized even if it is not so focused. It also has a wide recording range that eliminates the need to be aware of the reading angle (reading from an angle is also possible). Close-up reading is also unnecessary. The color code can be applied to a wide range of print media. In addition, the color code has an advantage that a free design is possible as long as it follows the color arrangement pattern. Therefore, it is possible to provide a code that does not break the entire image of the advertisement or the entire image such as a logo or a theme design.

  In addition, since the content information provided corresponding to the color code is managed by the intermediate server in the address (URL) of the server where the content information exists, the color code itself is always changed without being changed. The provision information corresponding to the color code can be changed. For example, in the conventional QR code (registered trademark), since the code itself indicates a URL, the URL cannot be changed after printing. Furthermore, the size of the color code is not affected by the size of the content information provided corresponding to the color code. This is because in the system using the color code, the URL corresponding to the color code is managed by the intermediate server.

  FIG. 4 shows a processing procedure among the mobile phone 103, the intermediate server 104, and the recipe server 105. The mobile phone 103 reads the color code in step 401. In step 402, the read color code is decoded into a color code number. In step 403, the acquired color code number is transferred to the intermediate server 104. The URL of the intermediate server 104 is assumed to be predetermined, and the request may be issued by embedding the color code number as a parameter in the URL. In step 421, the intermediate server 104 waits for a request from the mobile phone. In step 422, the color code number transferred from the mobile phone 103 is received, and the color code number database is searched with the color code number.

  FIG. 5 shows an example of the contents of the color code number database provided in the intermediate server 104. This database stores URLs corresponding to color code numbers. This URL is the address of the recipe server 105 that holds the page data of the dish information here. Note that the URL corresponding to each color code number can be arbitrarily set and changed by the administrator. By changing the URL corresponding to the color code number, the page data displayed from the color code can be easily changed without changing the color code itself.

  In step 423, the intermediate server 104 acquires the URL corresponding to the transferred color code number from the database of FIG. In this URL, a product ID is embedded as a URL parameter. The URL acquired in step 424 is returned to the mobile phone 103.

  The mobile phone 103 receives the URL in step 404. In step 405, the recipe server 105 is accessed based on the URL. This access is automatically performed without making the user aware of it. However, the received URL may be displayed and accessed by the user after confirming the URL.

  The recipe server 105 waits for a request from the mobile phone in step 441. When a request from the mobile phone 103 is received in step 442, the dish information database is searched based on the product ID embedded in the URL parameter in the request in step 443, and a dish information file corresponding to the product ID is acquired. In step 444, the contents of the acquired dish information file are returned to the mobile phone 103 for display.

  FIG. 6 shows an example of the contents of the dish information database. The dish information database holds a dish information file name corresponding to the product ID. The content of the dish information file is, for example, a screen 200 in FIG.

  The mobile phone 103 receives and displays the dish information at step 406. Thereby, for example, a display like the screen 200 of FIG. When a menu is selected in step 407 (for example, one dish is selected from the menu display 212 in FIG. 2B), a request for recipe information of the selected dish is transmitted to the recipe server 105 in step 408. . This request includes the recipe number of the recipe of the selected dish as a parameter. The recipe server 105 receives the request at step 445, acquires recipe information corresponding to the recipe number included in the request at step 446 from the recipe database, and stores the contents of the recipe information at the mobile phone 103 at step 447. Send to.

  FIG. 7 shows an example of the contents of the recipe database. The recipe database holds a recipe information file name corresponding to the recipe number. The content of this recipe information file is, for example, like a screen 200 in FIG.

  In step 409, the mobile phone 103 displays the received recipe information. Thereby, for example, a display like the screen 200 of FIG. When mail transmission is selected in step 410 (for example, when mail transmission 216 in FIG. 2D is selected), a mail transmission request is transmitted in step 411. This request includes the recipe number of the recipe information displayed in step 409 as a parameter. The recipe server 105 receives the request at step 448, and at step 449, the recipe information mail corresponding to the recipe number included in the request (a mail with the recipe information as a text may be used, or the recipe information file May be sent to the mobile phone 103. When the user instructs cancellation (end of processing) in steps 407 and 410, the processing is ended as it is.

  In addition, although the example using a mobile phone has been described in the above embodiment, other mobile terminal devices can be used instead of the mobile phone. Moreover, although the example which prints a color code on printed matter, such as an advertisement, was demonstrated, you may make it provide recipe information by reading the color code displayed, for example on the display for advertisement display arrange | positioned in the shop.

  In the above embodiment, the menu corresponding to the color code number is first displayed on the mobile phone, and the recipe information of the dish selected by the user from the menu is provided. Recipe information corresponding to can be directly provided.
