It is a figure which shows the superimposed display image by a notification part. It is a hardware block diagram of a portable terminal. It is a flowchart which shows the process of the portable terminal which concerns on this embodiment.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Where possible, the same parts are denoted by the same reference numerals, and redundant description is omitted.

  FIG. 1 is a block diagram illustrating functions of the mobile terminal 1 according to the present embodiment. As shown in FIG. 1, the mobile terminal 1 includes a camera 11, a position acquisition unit 12, a price identification unit 13, a currency identification unit 14, a storage unit 15, a corresponding currency selection unit 16, and a notification unit 17. It is equipped with. The portable terminal 1 is an information processing apparatus, and is a portable device such as a smartphone or a communication terminal such as a PC terminal. Hereinafter, each functional block will be described based on the functional blocks shown in FIG.

  The camera 11 has a function as input means for copying price information, which is information indicating the price, and inputting a price image, which is an image on which the price information is displayed, to the price specifying unit 13. Price information is, for example, a price tag of a product. The price information may include both numbers and currency symbols (for example, $ 100), or only numbers (for example, 100).

  Further, the camera 11 has a function as an input unit that projects a target image that is an image including money and inputs the target image to the money specifying unit 14 and the notification unit 17. A currency means the currency which the user who operates the portable terminal 1 possesses, for example. Money includes both banknotes and coins. The camera 11 inputs the projected image to the currency specifying unit 14 and the notification unit 17 at intervals of several ms to several tens of ms.

  The position acquisition unit 12 functions as a position acquisition unit that acquires position information of the mobile terminal 1 by base station positioning using the reception status of radio waves transmitted from the base station, GPS positioning using GPS, or the like. Have The position acquisition unit 12 acquires the position information of the mobile terminal 1 at intervals of several seconds to several tens of seconds, for example.

  The price specifying unit 13 has a function as a price specifying means for specifying a price based on price information. Specifically, the price specifying unit 13 specifies the price by recognizing the price image input from the camera 11. The image recognition by the price specifying unit 13 is performed by a conventionally known technique, for example, OCR (Optical Character Recognition) technique, and by referring to a plurality of numbers and currency symbol patterns registered in advance, price information is obtained. Recognize the numbers and currency symbols shown in.

  Further, the price specifying unit 13 may specify a currency unit using the position information of the mobile terminal 1 input from the position acquisition unit 12 and specify the price. Specifically, the price specifying unit 13 specifies the country in which the mobile terminal 1 is located from the location information of the mobile terminal 1 and specifies the currency unit in circulation in the country. And the price specific | specification part 13 detects the symbol of the currency unit specified from the positional information of the portable terminal 1 in the price image input from the camera 11, and recognizes a number from the image of the location vicinity where this symbol is described. To do. Note that the price specifying unit 13 may specify the price based on information manually input by the user instead of specifying the price by recognizing the price image input from the camera 11.

  The money specifying unit 14 has a function as money specifying means for recognizing the target image input from the camera 11 and specifying the type of money in the target image. Specifically, like the price specifying unit 13, the money specifying unit 14 specifies the type of money using a conventionally known technique such as an OCR (Optical Character Recognition) technique, and is input from the camera 11. The type of money in the target image is specified based on the target image thus obtained and the feature amounts (money reference information) of the plurality of types of money images stored in the storage unit 15 serving as storage means. The type of money is specified by recognizing a picture or a number in a bill / coin, for example. For recognition of pictures and numbers, template matching with money images stored in the storage unit, matching with feature quantities obtained using the SIFT method or SURF method using the mean-shift method, etc. This is performed by a known image processing technique. Moreover, you may recognize a color and a shape.

  An example of a plurality of types of money images (money DB) stored in the storage unit 15 will be described with reference to FIG. FIG. 2 is a diagram illustrating an example of the currency DB stored in the storage unit 15. As shown in FIG. 2, the money DB includes characteristics such as the shape and color of money (coins and banknotes) in each currency unit, that is, the feature amount used when the money specifying unit 14 specifies the type of money. Money standard information indicating corresponding features as feature quantities is stored.

  In addition, the currency identification unit 14 identifies a currency candidate using the position information of the mobile terminal 1 input from the position acquisition unit 12, and the currency standard information of the currency candidate stored in the storage unit 15, and The type of money in the target image may be specified from the target image. A money candidate is a money group that matches the currency unit used in the country specified by the location information of the mobile terminal 1. For example, if the position of the mobile terminal 1 is the United States, it can be assumed that the currency unit is dollars and cents, so the money candidates are 100 dollars, 50 dollars, 20 dollars, 10 dollars, 5 dollars, 1 dollars, 25 cents. It can be specified as 10 cents, 5 cents, and 1 cent.

  In this case, the currency specifying unit 14 is a currency candidate (100 dollars, 50 dollars, 20 dollars, 10 dollars, 5 dollars) among a plurality of money standard information included in the currency DB stored in the storage unit 15. Only the currency standard information of dollars, dollars, 25 cents, 10 cents, 5 cents, 1 cent) is used to specify the type of money in the target image.

  Further, when recognizing the target image input from the camera 11, the money specifying unit 14 specifies the money position that is the position of the money in addition to specifying the type of money. The money position is, for example, the center position of money indicated by two-dimensional coordinates. And the money specific | specification part 14 produces | generates the money table which linked | related the kind of money recognized image, the money reference | standard information of this money, and the money position of this money. The money reference information of money can be acquired by referring to the money DB stored in the storage unit 15. Note that the money table does not have to include money standard information.

  The money table will be described with reference to FIG. FIG. 3 is a diagram illustrating an example of a money table. The money table stores types, money reference information, and money positions of a plurality of moneys that have been image-recognized. The money position is, for example, the lower left point (0, 0), the lower right point (200, 0), the upper right point (200, 200), and the upper left point in the image input from the camera 11. Is represented by a two-dimensional coordinate with (0,200). The currency identification unit 14 inputs the currency table to the corresponding currency selection unit 16.

  Further, the money table may include money additional information for specifying the outline of money in addition to the money position. The money additional information includes the shape (for example, rectangular and circular sections) and size (for example, the position coordinates of the four corners in the case of a rectangle and the diameter in the case of a circle) of the recognized money.

  The corresponding currency selecting unit 16 has a function as a corresponding currency selecting unit that selects one or a plurality of currencies (corresponding currencies) corresponding to the price specified by the price specifying unit 13 based on the target image. Specifically, the corresponding money selecting unit 16 selects the corresponding money corresponding to the price specified by the price specifying unit 13 based on the type of money specified by the money specifying unit 14.

  A specific example will be described with reference to FIG. It is assumed that the money table shown in FIG. 3 is input from the money specifying unit 14 to the corresponding money selecting unit 16. Then, it is assumed that the price input from the price specifying unit 13 is 1 dollar and 15 cents. In this case, the corresponding money selection unit 16 selects the 1-dollar banknote in the second row, the 10-cent coin in the third row, and the 5-cent coin in the fourth row as the corresponding money in the money table shown in FIG. .

  Moreover, the corresponding money selection part 16 selects the one corresponding money from several options, when there are two or more choices of the corresponding money corresponding to the price which the price specific | specification part 13 specified. For example, the corresponding currency selection unit 16 preferentially selects a corresponding currency option including a currency having a small value as the corresponding currency.

  Specifically, it is assumed that the price input from the price specifying unit 13 is 10 dollars per dollar. In this case, the corresponding currency selection unit 16 selects the second dollar 1-dollar bill and the third row of 10 cent coins as the corresponding currency (option A) or 2 in the currency table shown in FIG. There are two options: a 1-dollar bill on the line, a 5-cent coin on the 4th line, and an option (referred to as option B) for selecting the 5-cent coin on the 5th line as the corresponding currency. In such a case, the corresponding money selection unit 16 preferentially selects the option B including the 5-cent coin, which is a money having a smaller value. In addition, the corresponding money selection part 16 is good also as selecting the option of the corresponding money containing the money with big value as a corresponding money preferentially. The user may be able to set in advance what option is preferentially selected as the corresponding currency.

  In addition, if the money held for the specified price does not correspond, for example, if there is money held as shown in FIG. 3, if 8 cents is determined from the price tag information, select the money that exceeds that amount. I decided to. In this case, 10 cents is selected as the corresponding currency.

  Next, the corresponding money selection unit 16 generates a post-selection money table in which the corresponding money is distinguished from other currencies in the money table. Specifically, the corresponding currency is distinguished from other currencies by performing a process such as setting a bit only for the corresponding currency in the currency table or deleting a currency other than the corresponding currency in the currency table. The corresponding currency selection unit 16 inputs the selected currency table to the notification unit 17.

  The notification unit 17 has a function as a notification unit that notifies the corresponding money. Specifically, the notification unit 17 superimposes and displays information indicating the corresponding currency based on the target image input by the camera 11. Conventionally known AR (AUGMENTED REALITY) technology may be used for the superimposed display.

  Specifically, the notification unit 17 refers to the selected money table input from the corresponding money selecting unit 16 to identify the type of the corresponding money, the money position of the corresponding money, and the additional money information. Thereby, the outline and position of corresponding money can be specified. The information indicating the corresponding money is displayed in the vicinity of the money position of the corresponding money. For example, as shown in FIG. 4, the information is indicated by a frame surrounded so as to border the outline of the corresponding money in the image. Therefore, the notification unit 17 notifies the user of the corresponding money by superimposing and displaying a line that surrounds the outline of the corresponding money in consideration of the outline and position of the corresponding money. Note that the information indicating the corresponding currency displayed superimposed on the target image by the notification unit 17 is not necessarily limited to a line that outlines the outline of the corresponding currency, for example, the currency position of the corresponding currency is indicated by an arrow, etc. Also good. In this case, additional currency information is not necessary.

  Here, the target image on which the information indicating the corresponding currency is superimposed and displayed by the notification unit 17 is created based on the image input from the camera 11, but as described above, the camera 11 has several ms to several tens of times. Since images are input at intervals of ms, even if the superimposed display position is determined based on the image input by the camera 11, it may be different from the current position. In this case, it is not preferable to simply superimpose and display information indicating the corresponding money based on the money position of the corresponding money shown in the selected money table.

  Of the moneys notified by the notification unit 17, it is determined that the money that is out of the screen (money not included in the input new target image) is already used for payment, While excluding the money from the money possessed by the user, the price reduced by the price of the money may be specified as a new price. In this way, the price (payment balance) that the user should pay may be updated as needed based on the information that is being paid. For example, if it is determined that 1 dollar has been paid for 1 cent and 10 cents, the same processing may be performed for the remaining 10 cents, and only 10 cents are superimposed. Of course, not only the paid amount is recognized from the image as described above, but it may be specified that the user has paid 1 dollar explicitly.

  In addition, although the currency specifying unit 14 basically captures and specifies the money held by the camera, it is possible to save the trouble of shooting if the user has previously specified the money. For example, the contents of the wallet may be entered manually, or if the contents of the wallet are not changed from the result recognized by the previous camera, the selection of “use information at the previous time” is selected. You may do it. In this case, since superimposed display is impossible, it is necessary to notify the user of money to be paid. For example, when one dollar bill and one 10 cent coin are to be paid, an effect close to the superimposed display can be obtained by explicitly displaying the image of the banknote and the coin and the required number on the screen of the information processing apparatus. For this presentation, a money image may be held in the money table.

  Therefore, the notification unit 17 compares the position of each currency in the target image for which the currency specification unit 14 has generated the currency table, in the image (the image input from the camera 11) that the notification unit 17 intends to superimpose. Information indicating the corresponding currency in the image input from the camera 11 after specifying how much the position of each currency has changed (identifying the amount of change by tracking the position of each currency) and considering the amount of change Is superimposed. As described above, such superimposed display is realized by the AR technology that has been conventionally known.

  Next, the hardware configuration of the mobile terminal 1 will be described with reference to FIG. FIG. 5 is a hardware configuration diagram of the mobile terminal 1. As shown in FIG. 5, the portable terminal 1 shown in FIG. 1 physically includes a CPU 101, a RAM 102 and a ROM 103, which are main storage devices, an input device 104, which is an input device, an output device 105 such as a display, and a network card.

  In addition, when the money is specified, the money position that is the position of the money in the target image is specified by the money specifying unit 14, the type of money specified by image recognition, the money reference information of the money, and the money of the money A currency table in which the positions are linked is generated (S8). The money table is input to the corresponding money selecting unit 16 by the money specifying unit 14.

  Subsequently, using the price specified in S4 and the money table generated in S8, the corresponding money selecting unit 16 selects one or a plurality of moneys (corresponding money) corresponding to the prices (S9, Corresponding currency selection step). Then, a selected currency table, which is a currency table in which the corresponding currency is distinguished from other currencies, is generated by the corresponding currency selection unit 16 and input to the notification unit 17.

  Finally, the notification unit 17 specifies the position of the corresponding currency from the selected currency table (S10, notification step), and indicates the corresponding currency in the vicinity of the specified corresponding currency position in the target image input by the camera 11. Information is superimposed and displayed (S11, notification step). With the above, a series of processing of the mobile terminal 1 ends.

  In addition, when information that is being paid is updated in real time, for example, it is determined that money deviated from the screen has already been paid after S11, the price specified in S4 is updated as needed until payment is completed. May be.

  Next, an information processing program for causing a computer to function as the portable terminal 1 will be described. The information processing program is provided by being stored in a computer-readable recording medium. Specifically, price information that is information indicating a price, and a target image that is an image including money are displayed.

Each of the modules described above operates according to the flowchart shown in FIG.

  Next, the effect of the portable terminal 1 of this embodiment is demonstrated. According to the mobile terminal 1 of the present embodiment, the corresponding currency that is the currency corresponding to the price is selected by the corresponding currency selection unit 16, and the corresponding currency is notified to the user by the notification unit 17. By this notification, the user can instantly recognize which currency should be paid for the price of the product. As a result, there is no fear that even when paying with foreign currency, it takes time to select the currency or paying with incorrect currency. That is, it is possible to smoothly purchase products using foreign currency.

  In the mobile terminal 1 of the present embodiment, the camera 11 inputs a price image that is an image displaying the price as price information, and the price specifying unit 13 specifies the price by recognizing the price image. By doing so, the price specification can be facilitated, and the purchase of goods using foreign currency can be facilitated.

  In the mobile terminal 1 of the present embodiment, the position acquisition unit 12 inputs position information indicating the position of the mobile terminal 1, and the price specifying unit 13 specifies a currency unit using the position information of the mobile terminal 1. By specifying the price, the price can be specified easily. Specifically, the price specifying unit 13 easily specifies the currency unit by using the position information, and recognizes the number corresponding to the price in the price image input from the camera 11, thereby identifying the price. Speed can be improved. Further, by using the currency unit specified from the position information, it is possible to prevent erroneous price specification.

  In the mobile terminal 1 of the present embodiment, the notification unit 17 superimposes and displays information indicating the corresponding currency on the target image input by the camera 11. By superimposing and displaying on the target image input by the camera 11, the user can more intuitively recognize the currency used for payment.
