Description

The present invention relates to a renaming processing device and a printed matter sales system.

At baseball stadiums and soccer stadiums, photographs (bromide) related to players are sold. For example, a PC and a printer are installed in the sales space, and the staff operates the PC to download the image from the server to the PC, print the image on paper with the printer, create a photo, and sell it.

Many images are stored on the server. In order to improve searchability when searching for an image to be printed, it is preferable to use a person's name (for example, a player's name) as the file name of the image. An image of a player taken with a digital camera is automatically given a file name composed of alphanumeric characters by the digital camera. In the past, the operator visually checked the image, considered a suitable file name, and manually changed the file name, so that the renaming work took time.

Recently, a service has been provided in which photographs taken by professional photographers during a match are printed out and sold on the day of the match. When such a service is provided, it is required to quickly rename the file name of the image file. However, if the name of the player shown in the image is unknown, the name must be searched from the list of players such as a directory, which causes a problem that it takes time and effort. Especially when multiple players are shown in one image, it takes time and effort to rename.

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

FIG. 1 is a schematic configuration diagram of a printed matter sales system according to an embodiment of the present invention. The print sales system is a system for selling prints such as photographs at event venues such as sports facilities and concert venues, and is a management device 5 for managing sales images and an operator terminal used by an operator who renames images. 7. Printer 4 that prints out printed matter (photograph), printer control device 3 that controls printer 4, accepts image selection from customers, and automatically prints out printed matter (photograph) when a fee is paid. An image printing device 2 and the like are provided. In the following embodiment, a case where a photograph of a player during a sports match is sold will be described.

A photograph of a player during a sports match is taken with a professional cameraman's camera 6. The image taken by the camera 6 is uploaded to the management device 5 and is sold on the day.

The file name of the captured image uploaded to the management device 5 is automatically assigned by the camera 6. The file name of the captured image is composed of alphanumeric characters such as "IMG5551.jpg" and "P505012.jpg", and the file name does not tell what kind of image it is.

A player's face image and name (name) are registered in the management device 5 in advance. The management device 5 analyzes the captured image, extracts the face image shown in the captured image, compares the extracted face image with the pre-registered face image, and obtains the degree of similarity. The pre-registered face image and the name are displayed on the operator terminal 7 in the order of similarity. The operator selects the name of the player shown in the photographed image with reference to the similarity displayed on the operator terminal 7. The management device 5 creates a new file name using the selected name, and changes the file name of the captured image to the new file name.

When multiple players are shown in the captured image, the operator selects the names one by one. A new file name is created using the names of multiple players.

For example, when a photographed image of the file name “IMG5531.jpg” showing two athletes as shown in FIG. 2 is uploaded to the management device 5, the management device 5 performs image analysis of the photographed image. , Extract the face image of each player. The management device 5 obtains the degree of similarity between the face image extracted from the captured image and the pre-registered face image.

When the operator selects the face image of one of the athletes in the captured image, the pre-registered face image and the name are displayed on the operator terminal 7 in descending order of similarity with the selected face image. The operator selects the name of this player by referring to the similarity. The same process is performed when the face image of the other player is selected. The management device 5 concatenates the selected names to create a file name of "01_OO Taro_△△ Daisuke.jpg", and changes (renames) the file name of the captured image. "01" in the file name is a serial number.

The printer control device 3 and the printer 4 are installed in the photo sales space of the event venue, and the staff operates the printer control device 3 to download the images to be sold from the management device 5. Since the captured image stored in the management device 5 has been renamed, for example, it is possible to search by the player name, narrow down the images, and download them.

Image data is transferred from the printer control device 3 to the printer 4 and printed out. The staff sells the photograph printed out from the printer 4 to the customer.

The management device 5 transmits the captured image after the renaming process to the image printing device 2. For example, the customer inputs the name of the player who wants to purchase the photograph into the image printing device 2 and searches for it. The image printing device 2 displays a thumbnail list screen of an image file including the player name input from the customer in the file name.

When the customer selects an image desired to be purchased, the image printing device 2 performs a billing process, accepts the money paid by the customer, and withdraws the change. After that, the selected image is printed out from the printer housed in the image printing device 2. The image printing device 2 can function as a photo vending machine.

As described above, according to the present embodiment, the management device 5 performs image analysis of the captured image and obtains the degree of similarity between the face appearing in the captured image and the pre-registered face image. The pre-registered face image and the name are displayed on the operator terminal 7 in the order of similarity. When renaming the image file name, the operator only needs to select the name of the pre-registered face image having a high degree of similarity. Therefore, the file name renaming process of the image file can be efficiently performed.

Next, the management device 5 having a function as a renaming processing device will be described. As shown in FIG. 3, the management device 5 is a computer having a storage unit 50 including a ROM (Read Only Memory), a RAM (Random Access Memory), a non-volatile memory, a hard disk device, and the like, and the storage unit 50 includes a storage unit 50. The renaming program, face image data, photographed image data, renaming processing result, etc. are stored. The face image data is, for example, a pre-registered face image in which a face image of an athlete and a player name are associated with each other. Further, the storage unit 50 may store a uniform number list in which the uniform numbers of the athletes and the athletes' names are associated with each other.

When the CPU (Central Processing Unit) of the management device 5 executes the renaming program, as shown in FIG. 3, the registration unit 51, the captured image receiving unit 52, the renaming processing unit 53, the image analysis unit 54, and the image transmitting unit 55 Function is realized.

The registration unit 51 accepts pre-registration of a player's face image and name via the operator terminal 7. For example, the registration unit 51 transmits a registration screen as shown in FIG. 4 to the operator terminal 7. The registration screen is provided with an image addition button 11, a name input area 12, a uniform number input area 13, a registration button 14, and the like. When the operator operates the operator terminal 7 and presses the image addition button 11, the image in the terminal can be selected. When the operator selects an image to be registered, the image is displayed in the image display area 10. Images can be added by dragging and dropping. Register at least one facial image for each player.

The player's name is input in the name input area 12, and the player's uniform number is input in the uniform number input area 13. When the registration button 14 is pressed, the face image and the player name (further uniform number) are stored in the storage unit 50 as the pre-registered face image. Pre-registration of such face images and names is performed for all athletes.

The captured image receiving unit 52 receives the captured image data from the camera 6 and stores it in the storage unit 50.

FIG. 5 is a flowchart illustrating the flow of the renaming process. The functions of the rename processing unit 53 and the image analysis unit 54 will be described with reference to the flowchart shown in FIG.

The renaming processing unit 53 creates a renaming processing screen and transmits it to the operator terminal 7. FIG. 6 shows an example of the rename processing screen. For example, the file name of the captured image to be renamed is displayed in the image file list 100 on the rename processing screen.

The operator selects an image file to be renamed (step S1). As shown in FIG. 7, the selected image is displayed in the image display area 102. The image analysis unit 54 analyzes the selected photographed image and extracts the facial image of the athlete in the photographed image (step S2). The extracted face images are displayed side by side in the extracted image display area 104 (step S3). In the example shown in FIG. 7, the face images G1 and G2 of the two athletes are extracted from the captured image and displayed in the extracted image display area 104.

In addition, the image analysis unit 54 calculates the degree of similarity between the pre-registered face image and the face image extracted from the captured image. The calculation of the similarity may be performed by a computer other than the management device 5. In that case, the image analysis unit 54 acquires the similarity calculation result from another computer. The degree of similarity of the face image extracted from the captured image is calculated for all the pre-registered face images. For example, when the face images of 100 athletes are pre-registered, the similarity to the pre-registered facial images of 100 athletes is calculated for each of the face images G1 and G2.

The operator operates the operator terminal 7 and selects a face image for which a person's name is to be specified (step S4). For example, the face image G1 is selected as shown in FIG. The rename processing unit 53 displays the pre-registered face image and the name in the pre-registered image display area 106 in descending order of similarity to the selected face image G1 (step S5). At this time, the similarity is also displayed.

The operator selects the person in the face image G1 as shown in FIG. 9 with reference to the similarity (step S6). Since the operator can check in order from the person with the highest degree of similarity, it is easy to identify the person.

The rename processing unit 53 generates a file name including the name of the selected person and displays it in the completed file name display area 120 (step S7). The operator can select whether or not to put the serial number in the file name by using the serial number addition button 116, and if so, whether to put it at the beginning or the end of the file name. FIG. 9 shows a case where the serial number is inserted at the beginning of the file name.

When the clear button 124 is pressed, the file name is deleted and the file name can be generated again.

If there is a player who wants to put the person's name in the file name among the face images extracted from the captured image (step S8_No), the unselected face image in the extracted image display area 104 is selected, and the same as above is performed. Perform processing (steps S4 to S7).

For example, when the face image G2 is selected as shown in FIG. 10, the pre-registered face image and the name are displayed in the pre-registered image display area 106 in descending order of similarity to the image G2. When the operator selects a person corresponding to the face image G2, the person name is reflected in the file name. For example, by connecting the file name "01_OO Taro.jpg" to the person name "△△ Daisuke" selected this time, the file name is "01_OOtaro_△△ Daisuke.jpg".

When the operator presses the rename execution button 122, the rename processing unit 53 executes the rename and changes the file name (step S9). The file name of the captured image data may be changed, or the file name of the copied captured image data may be changed. The data whose file name has been changed is saved in the storage unit 50 as a result of the renaming process.

Rename processing is performed on all the captured image files displayed in the image file list 100 (step S10).

The image transmission unit 55 transmits the renamed image data to the printer control device 3 in response to a request from the printer control device 3. Further, the image transmission unit 55 transmits the renamed image data to the image printing device 2.

As described above, according to the present embodiment, the captured image is analyzed and the facial images of a plurality of persons appearing in the image are extracted. When the operator selects the extracted face image, the pre-registered face images are displayed in order of similarity. The operator simply selects the person's name by referring to the similarity, and a new file name is automatically generated. Therefore, even when a plurality of people are shown in the image, the name of each person can be easily specified regardless of the knowledge and experience of the operator, and the renaming work can be performed efficiently.

In the above embodiment, an example of generating a new file name using a person name has been described, but a scene or the like may be included in the file name in addition to the person name. For example, pre-register words that are often used in sports competitions. The registered words are displayed in the registered word display areas 108 and 112. When the operator selects a word to be used as the file name, the selected word is displayed in the selected word display areas 110 and 114 and reflected in the file name.

For example, in the example shown in FIG. 10, when the word "smile" in the registered word display area 112 is further selected, a file name "01_OO Taro_△△ Daisuke_smile.jpg" is generated.

In the above embodiment, when displaying the pre-registered face image in the pre-registered image display area 106, the pre-registered face image whose similarity is equal to or less than a predetermined threshold value may be displayed with the similarity set to 0%. As a result, images with low similarity can be excluded from the candidates.

The image analysis unit 54 may perform scene analysis of the captured image, and the threshold value for setting the similarity to 0% may be changed depending on the scene. In high-five scenes and baseball batting scenes, the face may be hidden and the similarity may be calculated to be low even for the person's face image. For example, normally, the threshold value is set to 75%, and when it is determined by the scene analysis that the scene is a high five or batting scene, the threshold value is changed to 30%. This makes it easier to search for player names.

Of the plurality of people in the captured image, the out-of-focus face image may not be extracted.

When multiple face images are pre-registered for one player, the average value of the similarity of each face image is calculated, and the pre-registered face image with the closest similarity to the calculated average value is the pre-registered image display area. It may be displayed in 106, or the pre-registered face image having the highest degree of similarity among the plurality of face images may be displayed in the pre-registered image display area 106.

The player name may be specified by reading the uniform number in the captured image by OCR (optical character recognition) and referring to the uniform number list stored in the storage unit 50.

The above-mentioned rename program may be stored in a recording medium, read by a computer, and executed. The recording medium is not limited to a removable one such as a magnetic disk or an optical disk, and may be a fixed recording medium such as a hard disk device or a memory. Further, the rename program may be distributed via a communication line (including wireless communication) such as the Internet. Further, the program may be encrypted, modulated, compressed, and distributed via a wired line or wireless line such as the Internet, or stored in a recording medium.

The present invention is not limited to the above-described embodiment as it is, and at the implementation stage, the components can be modified and embodied within a range that does not deviate from the gist thereof. In addition, various inventions can be formed by an appropriate combination of the plurality of components disclosed in the above-described embodiment. For example, some components may be removed from all the components shown in the embodiments. In addition, components across different embodiments may be combined as appropriate.
