Description

The present invention relates to an information processing device, a printing system, a method, and a program.

In recent years, it has become possible to print nail art on nails using a printer. Hereinafter, a printer for printing nail art on nails will be referred to as a nail printer. When printing nail art on a user's nails, it is necessary to set a print area based on the position and size of the nail. As an example of a method for setting a print area, there is a method of setting a print area by executing a nail detection process using a learning model. Note that the object detected in this way is not limited to nails, and faces and the like may also be detected. Patent Document 1 describes a method of performing marginless printing by varying the amount of overflow of print data.

The following embodiments are described in detail with reference to the attached drawings. Note that the following embodiments do not limit the invention according to the claims. Although the embodiments describe multiple features, not all of these multiple features are necessarily essential to the invention, and multiple features may be combined in any manner. Furthermore, in the attached drawings, the same reference numbers are used for the same or similar configurations, and duplicate explanations are omitted.

[First embodiment]
The printing system in this embodiment includes an information processing device 101 and a printer (printing device) 151. In this embodiment, a tablet terminal is used as an example of the information processing device 101. The information processing device 101 is not limited to a tablet terminal. As the information processing device 101, various devices such as a mobile terminal, a notebook PC, a smartphone, a PDA (Personal Digital Assistant), and a digital camera can be applied. In this embodiment, an inkjet printer, a 3D printer, and the like can be applied as the printer. In addition, the printer in this embodiment may be a multifunction device having multiple functions such as a copying function, a FAX function, and a printing function. The printer in this embodiment has a function of directly drawing on the nails of a person's hand, for example. In this embodiment, the information processing device 101 and the printer 151 are described as separate devices, but a configuration using a device that includes the functions of both devices integrally may be used.

1 is a diagram showing an example of the configuration of a printing system including an information processing device 101 and a printer 151 according to the present embodiment. FIG. 1(a) shows a block configuration of the information processing device 101 and the printer 151. FIG. 1(b) shows the external appearance of the printer 151. Below, the system configuration of the information processing device 101 and the printer 151 will be described with reference to FIG. 1(a) and FIG. 1(b). As shown in FIG. 1(a), the information processing device 101 has an input interface 102, a CPU 103, a ROM 104, a RAM 105, an external storage device 106, an output interface 107, a communication unit 109, and a GPU 110. These are connected to each other so as to be able to communicate with each other via a system bus. The input interface 102 is an interface for receiving data input and operation instructions from a user via an operation unit (not shown) such as a physical keyboard, a button, and a touch panel. In this embodiment, at least a portion of the display unit 108 and the operation unit, which will be described later, are integrated, and a configuration will be described in which, for example, screen output and reception of operations from the user are performed on the same screen.

The CPU 103 is a system control unit, and controls the entire information processing device 101, such as executing programs and starting hardware. The ROM 104 stores data such as a control program executed by the CPU 103, a data table, an embedded operating system (hereinafter referred to as OS), and programs. In this embodiment, each control program stored in the ROM 104 performs software execution control such as scheduling, task switching, and interrupt processing under the management of the embedded OS stored in the ROM 104. The RAM 105 is composed of an SRAM (Static Random Access Memory) or a DRAM (Dynamic Random Access Memory). The RAM 105 may hold data by a primary battery for data backup (not shown). In that case, the RAM 105 can store data such as program control variables without volatilizing them. The RAM 105 also has a memory area for storing setting information for the information processing device 101 and management data for the information processing device 101. The RAM 105 is also used as the main memory and work memory for the CPU 103.

The external storage device 106 stores an application that provides a print execution function, a print information generation program that generates print information that can be interpreted by the printer 151, and the like. The external storage device 106 also stores various programs, such as an information transmission/reception control program that transmits and receives information to and from the printer 151 connected via the communication unit 109, and various information used by these programs. The output interface 107 is an interface that controls the display of data by the display unit 108 and the notification of the status of the information processing device 101. The display unit 108 is composed of an LED (light-emitting diode) or an LCD (liquid crystal display), and performs the display of data and the notification of the status of the information processing device 101. Note that a soft keyboard having keys such as numeric input keys, mode setting keys, a decision key, a cancel key, and a power key may be provided on the display unit 108 to accept input from the user via the display unit 108. The display unit 108 may also be configured as a touch panel display, as described above. The display unit 108 is connected to the system bus via the output interface 107.

The communication unit 109 is configured to connect to an external device such as the printer 151 and perform data communication. The communication unit 109 can be connected to, for example, an access point (not shown) in the printer 151. By connecting the communication unit 109 to the access point in the printer 151, the information processing device 101 and the printer 151 can wirelessly communicate with each other. The communication unit 109 may directly communicate with the printer 151 by wireless communication, or may communicate via an external access point (for example, the access point 131) located outside. Examples of wireless communication methods include Wi-Fi (Wireless Fidelity) (registered trademark) and Bluetooth (registered trademark). Examples of the access point 131 include devices such as a wireless LAN router. In this embodiment, a method in which the information processing device 101 and the printer 151 are directly connected without going through the external access point 131 is called a direct connection method. A method in which the information processing device 101 and the printer 151 are connected via the external access point 131 is called an infrastructure connection method. Note that the information processing device 101 and the printer 151 may also be connected by wire using a USB cable or the like.

Since GPU 110 can perform efficient calculations by processing more data in parallel, when processing a learning model such as deep learning, the processing may be performed by GPU 110. In this embodiment, GPU 110 may be used in addition to CPU 103 for processing using the learning model. Specifically, when executing a learning program including a learning model, CPU 103 and GPU 110 cooperate to perform calculations to execute the processing using the learning model. Note that the processing using the learning model may be calculated only by CPU 103 or GPU 110.

In this embodiment, it is assumed that a predetermined application is stored in the ROM 104 or the external storage device 106. The predetermined application is, for example, an application program for sending a print job to the printer 151 to print nail art data in response to an operation from a user. An application having such a function is hereinafter referred to as a nail app. Note that the nail app may have other functions in addition to the print function. For example, the nail app in this embodiment may have a function of communicating with the printer 151 and activating the camera of the photographing unit 157 of the printer 151. That is, the nail app may have a function of sending a camera activation job to the printer 151 in addition to the print job. Also, the predetermined application stored in the ROM 104 or the external storage device 106 is not limited to the nail app, and may be an application program having a function other than printing.

The printer 151 has a ROM 152, a RAM 153, a CPU 154, a print engine 155, a communication unit 156, and a photographing unit 157. These are connected to each other via a system bus. FIG. 1B is a schematic diagram showing the appearance of the printer 151. As shown in FIG. 1B, the printer 151 is provided with a print object insertion section 158, which is a space for inserting a print object. FIG. 1B shows a state in which a user inserts his or her own hand into the print object insertion section 158. Thus, in this embodiment, it is assumed that a human hand is inserted into the print object insertion section 158. In addition, in this embodiment, the print object is, for example, a nail. The print object insertion section 158 is equipped with four rails for placing fingers, and the user can insert one to four fingers. Each of the four rails is independent, and it is possible to adjust the height of the nail to the optimal height for printing by raising and lowering each rail. This raising and lowering operation is performed in response to an instruction from the nail app, and the target rail is raised and lowered based on the rail number received from the nail app. In this embodiment, an example is shown in which fingernails are printed, but the printing can also be done on toenails.

The ROM 152 stores data such as control programs, data tables, and OS programs executed by the CPU 154. In this embodiment, each control program stored in the ROM 152 performs software execution control such as scheduling, task switching, and interrupt processing under the management of the embedded OS stored in the ROM 152. The RAM 153 is composed of an SRAM or a DRAM. The RAM 153 may hold data using a primary battery for data backup (not shown). In this case, the RAM 153 can store data such as program control variables without volatilizing them. The RAM 153 also has a memory area for storing setting information for the printer 151 and management data for the printer 151. The RAM 153 is also used as the main memory and work memory of the CPU 154, and can temporarily store print information and various information received from the information processing device 101.

The CPU 154 is a system control unit, and controls the entire printer 151 by executing a program and starting up hardware. The print engine 155 forms an image on a recording medium such as a nail inserted in the print target insertion unit 158 using a recording agent such as ink based on information stored in the RAM 153 or a print job received from the information processing device 101. The communication unit 156 has an access point for connecting to an external device such as the information processing device 101 as an access point inside the printer 151. This access point can be connected to the communication unit 109 of the information processing device 101. The communication unit 156 may communicate directly with the information processing device 101 by wireless communication, or may communicate via an external access point 131. The communication unit 156 may also be provided with hardware that functions as an access point, or may operate as an access point by software for functioning as an access point.

The photographing unit 157 is a device having a photographing function. The device having the photographing function is attached to and installed in the printer 151. The photographing unit 157 has a function of photographing a predetermined area including a printing object (e.g., a nail) inserted into the printing object insertion unit 158, and transmitting the photographed image (still image or moving image) to the information processing device 101 in real time. In this embodiment, the photographing unit 157 photographs moving images and still images. The device having the photographing function is a camera module composed of at least a lens and an image sensor. The lens photographs the printing object inserted into the printing object insertion unit 158 and forms an image on the image sensor. The image sensor converts the light photographed by the lens into an electrical signal that can be processed by the CPU 154. If it has such a function, a smartphone, a mobile terminal, a digital camera, or the like may be used as the device having the photographing function. The print engine 155 prints on the printing object inserted into the printing object insertion unit 158. Note that the printer 151 may be equipped with a memory such as an external HDD or SD card, and the information stored in the printer 151 may be stored in the memory. Furthermore, the configurations of the information processing device 101 and the printer 151 are not limited to those shown in FIG. 1, and may include appropriate configurations according to the functions that each device can execute.

Next, the terms used in this embodiment will be explained. In this embodiment, nail art is printed mainly on the nails. Also, in this embodiment, nail art is printed on each nail of one hand. Generally, the nail art printed on each nail has the same concept, but the nail art printed on each nail may not be completely the same. For example, a nail art set of design A includes 10 pieces of nail art (nail art corresponding to each of the 10 nails), and although the 10 pieces of nail art have a common design concept, they may not have completely the same pattern. In light of the above, the terms are defined as follows in this embodiment.

- "Nail image data": Refers to image data of nail art to be performed on one nail.

- "Nail art data": refers to a collection of multiple nail image data. In other words, nail art data can also be considered a data set of multiple nail image data. Typically, it is image data that aggregates images of each nail image data corresponding to the nail art of 10 nails on a total of right and left hands. The nail art data may be data of image data of 10 nails (i.e., a set of 10 image data), or it may be image data of 10 nails combined into a single image. In this way, when referred to as "nail image data," it refers to data of images of nail art for individual nails, and when referred to as "nail art data," it refers to a set of data of images of nail art for 10 nails.

In this embodiment, the CPU 103 of the information processing device 101 executes a program of the nail app stored in the ROM 104 or the external storage device 106 to start up the nail app. Then, by using the nail app, the user can print nail art on the nail by reflecting the nail image data of the nail art data selected by the user in the print area. That is, the following example operation is performed using the nail app.

(1) The application stores nail image data in a multi-hierarchical structure.

(2) The user selects nail art data on the application.

(3) The application activates the camera inside the printer 151.

(4) The application makes it possible to display camera images (capture data) sent from the printer 151.

(5) The user inserts his/her hand into the printer 151.

(6) The application detects the nail area from the camera image and sets the nail area on which to print the nail art.

(7) The application generates print data based on the nail image data selected by the user and the detected nail area.

(8) The application reflects the print data in the specified print area.

(9) If the user wants to adjust the set print area, he or she edits the print area.

(10) The application causes the printer 151 to print based on the print data reflected in the print area.

In this embodiment, in steps (1) and (7) above, a configuration is described in which nail art data is stored in a multi-layered structure, and print data is generated based on the nail art data selected by the user and the detected nail area. Note that the user who places his or her hand in the printer 151 and the user who operates the application may be the same user or different users.

The graphical user interface (hereinafter referred to as GUI) screen displayed by the nail app will be described first. The GUI screen described below is displayed on the display unit 108 by the CPU 103 that executes the nail app. The input interface 102 will be described as functioning as an operation unit integrated with the display unit 108. There are four main types of GUI screens for the nail app in this embodiment, which are referred to as first to fourth GUI screens. FIG. 2 is an example of the first GUI screen, which is a nail art data selection screen. FIG. 5 is an example of the second GUI screen, which is a nail image data setting screen. FIG. 3 is an example of the third GUI screen, which is a print data creation screen. FIG. 11 is an example of the fourth GUI screen, which is a nail image data editing screen. Below, the GUI screens of the nail app will be described using each screen.

2 is a diagram showing a nail art data selection screen 201 as an example of the first GUI screen. As shown in FIG. 2, the nail art data selection screen 201 has a nail art data display area 202 and a decision button 204. In the nail art data display area 202, a plurality of nail art data corresponding to each design concept of the nail art to be printed on each nail is displayed. Specifically, four nail art data 203 are displayed on the screen in FIG. 2. One nail art data 203 includes ten types of nail image data corresponding to the nails of the thumb, index finger, middle finger, ring finger, and little finger of the left hand and right hand. The user can select one or more nail art data 203, and can also cancel the selected nail art data 203. As an example of a method in which the user selects or cancels the nail art data 203, the user can select the nail art data 203 by tapping the nail art data 203 once. In addition, the user can cancel the selection state by tapping the selected nail art data 203 once more.

When the user selects one or more nail art data 203 from the nail art data display area 202 and then presses the confirm button 204, the nail art data selection screen 201 is replaced with a nail image data setting screen 501 shown in FIG. 5. In this embodiment, the operation of various buttons is referred to as "pressing", and the operation of each area is described as a touch panel operation, such as "tapping", "touching", "pinch in", and "pinch out", but these are merely examples. For example, the pressing of various buttons may be realized by touching various buttons on a touch panel. Furthermore, each area may be operated by cursor operation using a mouse or the like. Furthermore, the input interface 102 may be provided with various directional buttons, and each area may be operated by the directional buttons.

Figure 5 is a diagram showing a nail image data setting screen 501 as an example of a second GUI screen. The nail image data setting screen 501 shown in Figure 5 has a nail art data display area 502, a left hand preview area 503, a right hand preview area 504, a selection mode change switch 505, a deselect button 506, and a setting completion button 507. The nail art data display area 502 is an area that displays the nail art data selected by the user on the nail art data selection screen 201.

The left hand preview area 503 includes a total of five nail areas 508, from the thumb to the little finger of the left hand. The right hand preview area 504 includes a total of five nail areas 508, from the thumb to the little finger of the right hand. The user selects nail art data or nail image data from the nail art data display area 502. As a result, the selected nail art data or nail image data is reflected in the nail areas 508 in the left hand preview area 503 and right hand preview area 504.

The selection mode changeover switch 505 is a switch for switching the method of selecting nail art data or nail image data to be reflected in the nail area 508 included in the left hand preview area 503 and the right hand preview area 504. When the bulk selection mode is ON, the nail art data selected by the user from the nail art data display area 502 can be reflected collectively in the nail areas 508 included in both the left hand preview area 503 and the right hand preview area 504. When the bulk selection mode is OFF, the nail image data selected by the user from the nail art data display area 502 can be reflected in either the nail area 508 included in the left hand preview area 503 or the right hand preview area 504.

The deselect button 506 is a button that can be selected when nail image data has already been reflected in at least one nail area 508 included in the left hand preview area 503 and the right hand preview area 504. When the user presses the deselect button 506, the selection of all reflected nail image data is deselected and the nail image data returns to an unselected state. The setting completion button 507 is a button that can be selected when nail image data has been reflected in one or more nail areas 508 included in the left hand preview area 503 and the right hand preview area 504. When the user presses the setting completion button 507, the print data creation screen 301 shown in FIG. 3 is displayed instead of the nail image data setting screen 501.

Figure 3 is a diagram showing a print data creation screen 301 as an example of a third GUI screen. The print data creation screen 301 shown in Figure 3 has a setting data display area 302 and a print target display area 303. The print data creation screen 301 also has a printer search button 304, a printer name display area 305, a capture button 306, a preview area 307, a print area setting button 308, and a print button 310. The preview area 307 displays a moving image of the finger before the image is captured, and the captured image after the image is captured. Then, when a print area 309 is set in the captured image on the screen of Figure 4 described later, the preview area 307 displays the captured image of the finger combined with a display item indicating the print area 309.

The set data display area 302 is an area where the nail image data set on the setting screen 501 of the nail image data shown in FIG. 5 is displayed divided into up to four pieces of data for the left and right hands. In FIG. 3, as an example of how to divide the set data, one piece of data is displayed for the index finger, middle finger, ring finger, and little finger of the left hand, one piece of data for the thumb of the left hand, one piece of data for the index finger, middle finger, ring finger, and little finger of the right hand, and one piece of data for the thumb of the right hand. The set data display area 302 in FIG. 3 shows a case where nail image data is set for all the nails on the left and right hands. As shown in FIG. 3, the set data display area 302 displays set data 302a for the index finger, middle finger, ring finger, and little finger of the left hand, and set data 302b for the thumb of the left hand. In addition, the set data display area 302 displays set data 302c for the index finger, middle finger, ring finger, and little finger of the right hand, and set data 302d for the thumb of the right hand. Each area of setting data 302a-302d has four slots for nail image data.

In the print target display area 303, four icons are displayed to indicate which nail each of the setting data 302a to 302d corresponds to. That is, as in the setting data display area 302, one data is displayed for the index finger, middle finger, ring finger, and little finger of the left hand, one data for the thumb of the left hand, one data for the index finger, middle finger, ring finger, and little finger of the right hand, and one data for the thumb of the right hand. As mentioned above, the print target display area 303 shown in FIG. 3 shows a display when nail image data is set for all the nails on the left and right hands. Icon 303a indicates that the setting data 302a corresponds to the index finger, middle finger, ring finger, and little finger of the left hand, and icon 303b indicates that the setting data 302b corresponds to the thumb of the left hand. Icon 303c indicates that setting data 302c corresponds to the index finger, middle finger, ring finger, and little finger of the right hand, and icon 303d indicates that setting data 302d corresponds to the thumb of the right hand.

When the user presses the printer search button 304, a process is executed to search for a printer that can communicate with the nail app. If one or more printers, including printer 151, are found as a result of the search, the nail app displays information identifying each of the discovered printers. The information identifying the discovered printers is displayed in a list, and the user can select any one of the printers from the list. In this embodiment, it is assumed that the user selects printer 151. A printer name for uniquely identifying the selected printer 151 is displayed in the printer name display area 305. Note that the nail app can automatically search for a printer and display a list of printers not only when the user presses the printer search button 304, but also when the screen transitions to the print data creation screen 301 in a state where a printer is not registered.

The capture button 306 is a button for communicating with the printer 151 displayed in the printer name display area 305 by being pressed by the user, receiving a moving image captured by the capture unit 157 of the printer 151 in real time and displaying it in the preview area 307. In this embodiment, it is assumed that a human hand is inserted into the print target insertion section 158. For this reason, for example, when a user inserts one hand and presses the capture button 306 with the other hand, an image of the user's fingertips including nails is displayed in real time in the preview area 307. Note that the display of moving images, etc. in the preview area 307 is not limited to when the capture button 306 is pressed. For example, it is possible that communication with the printer 151 is possible when transitioning to the print data creation screen 301 in a state where the printer 151 has already been registered. In this case, the nail app automatically communicates with the printer 151 when transitioning to the print data creation screen 301, and can receive a moving image captured by the capture unit 157 of the printer 151.

The above-mentioned use of the printer 151 is just one example, and other uses are also possible. For example, the setting screen 501 for nail image data may have a capture button, and a customer of the nail salon may insert one hand into the setting screen 501 for the nail salon, and an employee of the nail salon may press the capture button on the setting screen 501 for the nail image data. The print area setting button 308 is a button that, when pressed by the user while a moving image is displayed in the preview area 307, transitions to an area setting mode in which the print area 309 is set.

When the print area setting button 308 shown in FIG. 3 is pressed, the mode transitions to an area setting mode in which the print area 309 can be set. FIG. 4 is a diagram for explaining an example of a method for automatically detecting the nail area from a still image and setting the print area 309. Note that the preview area 307 and the print setting button 308 shown in FIG. 4 are displayed instead of the preview area 307 and the print area setting button 308 in FIG. 3. Alternatively, when the print area setting button 308 shown in FIG. 3 is pressed, the preview area 307 and the print setting button 308 shown in FIG. 4 may be displayed overlapping the entire screen shown in FIG. 3 or instead of the entire screen shown in FIG. 3.

First, the user presses the print area setting button 308 in FIG. 4 to set the preview area 307 to the area setting mode. When the print area setting button 308 in FIG. 4 is pressed, the finger is captured as a still image. Alternatively, a frame of the moving image being captured, which is displayed when the print area setting button 308 is pressed, is generated as a still image of the finger. In this way, the nail app acquires from the printer 151 a still image of the user's hand including the nail, which is captured by the imaging unit 157, and automatically detects the nail area from the still image to set the print area 309. As an example of a method for automatically detecting the nail area, a learning model generated by machine learning may be used. The learning model used here is a learning model that has been trained to output the result of detecting the nail area when a still image including the nail is input. The output nail area is automatically set as the print area 309 as shown in FIG. 4. Then, a display item indicating the print area 309 is displayed as shown in FIG. 4. In FIG. 4, a display item including an image to be printed on the nail and a dotted frame clearly indicating the image is displayed as a display item. However, this is not limited to FIG. 4, and the display item may include only the image, or may include only the frame. Note that the image and the frame are displayed at a size and position corresponding to the size and position of the print area 309, respectively.

Furthermore, detection of the nail area is performed for each finger; for example, in the case of four fingers, detection of the nail area is performed four times. When displaying a display item indicating the print area 309, which is the detection result, an image (finger image) is displayed for each finger in the preview area 307; for example, in the case of four fingers, four finger images are displayed in the preview area 307. The print area 309 is displayed on the finger images, one print area 309 is displayed for each finger image, and a display item indicating the set print area 309 is displayed.

In this way, after the print area 309 is set, an image (image to be printed on the nail) corresponding to the setting data selected by the user from the setting data display area 302 is automatically reflected in the print area 309. The user can freely change the size of the print area 309. The user can also delete the set print area 309. The nails on which the user wants to print nail art may be all the nails of the finger of the hand, or may be only some of the finger nails. For this reason, in this embodiment, the user can set the desired print area 309. In addition, since the user's nails are assumed to be the printing target on which the image is reflected in this embodiment, the size of the set print area 309 may differ from one another. Therefore, in this embodiment, the user can insert his/her hand into the printer 151 and set the print area 309 while checking the image of the actual nail, thereby printing the nail art at an appropriate position on the nail. In addition, the print area 309 once set may be followed in subsequent image recognition processing, etc. For example, if the position of the finger (or nail) shifts within the printer 151 after the user sets the print area 309, the print area 309 may be automatically changed by making the image area of the set print area 309 follow it.

When any of the four finger images in the preview area 307 in FIG. 3 is selected, the screen transitions to a nail image data editing screen 1101, which is an example of a fourth GUI screen shown in FIG. 11. The nail image data editing screen 1101 shown in FIG. 11 has a completion button 1102, a setting data editing area 1103, a nail image data layer display area 1104, a button 1105 for executing editing of each layer, and a display/non-display button 1106 for each layer. The setting data editing area 1103 displays the nail image data of the selected finger. As shown in FIG. 11, the nail image data layer display area 1104 displays a display area 1104a for displaying data of the first layer of the nail image data. Also, the layer display area 1104 displays a display area 1104b for displaying data of the second layer of the nail image data and a display area 1104c for displaying data of the third layer of the nail image data. For example, if the nail image data of the second layer or the third layer is not held, it may not be displayed. The process of storing nail image data in a multi-hierarchical structure in advance will be described later.

In each of the display areas 1104a to 1104c, buttons 1105a to 1105c for executing editing of each layer and display/hide buttons 1106a to 1106c for each layer are displayed. For example, when the user taps the buttons 1105a to 1105c for executing editing of each layer, the buttons switch between "editing" and "edit". The user can freely edit the nail image data of the layer that is "editing". For example, when the user taps the display/hide button 1106 for each layer, the icon display switches from a circle to a cross. The nail image data of the layer with the circle icon is displayed in the setting data editing area 1103. For example, in the example of the editing screen 1101 of the nail image data shown in FIG. 11, the button 1105a for executing editing of the first layer is displayed as "editing". And the display/hide button 1106a for the first layer and the display/hide button 1106b for the second layer are circled. Therefore, the setting data editing area 1103 displays the nail image data of the first and second layers, and allows editing of the nail image data of the first layer. In this case, the user can freely set the size of the nail image data of the first layer within a certain limited range. The contents of the restrictions will be described later. When the user completes the editing, he/she presses the completion button 1102 and transitions back to the print data creation screen 301. It should be noted that the preview area 307 and the area setting button 308 shown in FIG. 4 are assumed to be displayed overlapping the entire screen shown in FIG. 3 or in place of the entire screen shown in FIG. 3. In that case, if the user gives an instruction to end in the display state shown in FIG. 4, the area setting mode ends and the screen transitions to the print data creation screen 301 shown in FIG. 3.

The print button 310 on the print data creation screen 301 in FIG. 3 is a button that instructs the user to start printing. When the print button 310 is pressed, the nail app creates print data for printing on the nails based on the setting data selected by the user from the setting data display area 302, which is reflected in the print area 309. The nail app then sends the created print data to the printer 151 displayed in the printer name display area 305. In the example shown in FIG. 3, the print data is created by extracting four print areas 309 from the preview area 307. The printer 151 executes printing on the nails based on the print data sent from the nail app.

Figure 6 is a diagram showing an example of a block configuration of software of the information processing device 101 for realizing the above-mentioned functions. The information processing device 101 has a nail app 600. The CPU 103 of the information processing device 101 executes the program of the nail app 600 stored in the ROM 104 or the external storage device 106, thereby making it possible for the CPU 103 to execute each function of the nail app 600. The nail app 600 has a display control unit 610. The display control unit 610 has a function of displaying a GUI screen including the nail art data selection screen 201 shown in Figure 2, the nail image data setting screen 501 shown in Figure 5, and the print data creation screen 301 shown in Figure 3 on the display unit 108. In addition, the display control unit 610 has the function of the input interface 102, and performs various controls in response to operation instructions input by the user. The display control unit 610 has a nail art data selection receiving unit 611, a nail image data setting unit 612, a photography instruction unit 613, an image display control unit 614, a nail detection unit 615, a print area setting unit 616, a reflection data receiving unit 617, a reflection execution unit 618, and a print instruction unit 619.

The nail art data selection receiving unit 611 receives the selection of the nail art data 203 from the user as shown in FIG. 2, and acquires the selected nail art data 203. The nail image data setting unit 612 acquires the nail image data set by the user in the nail area 508 of the left hand preview area 503 and the right hand preview area 504 as shown in FIG. 5. The shooting instruction unit 613 detects the pressing of the shooting button 306 in FIG. 3 or the transition to the print data creation screen 301 in a state in which the printer 151 is registered, and instructs the printer 151 to shoot a moving image in response to the detection. The image display control unit 614 controls the display in the preview area 307 based on the image data of the moving image transmitted from the printer 151. The nail detection unit 615 performs nail detection by analyzing the captured image, and outputs the print area 309 based on the result of the nail detection. The print area setting unit 616 sets the print area 309 on the preview area 307 according to the instruction from the user. The reflection data receiving unit 617 receives setting data selected by the user from the setting data display area 302, and associates the selected setting data with the print area 309. The reflection execution unit 618 reflects the setting data selected by the user from the setting data display area 302 in the corresponding print area 309. The print instruction unit 619 creates print data for printing by the printer 151 based on the setting data reflected in the print area 309, and transmits the created print data to the printer 151.

Figure 7 is a sequence diagram showing an example of the nail print process of this embodiment. The processing of the nail app 600 in Figure 7 is performed by the CPU 103 of the information processing device 101 expanding the program code stored in the ROM 104 or the external storage device 106 into the RAM 105 and executing it. Alternatively, some or all of the processing in Figure 7 may be performed by hardware such as an ASIC or electronic circuit. Below, using Figure 7, a flow will be described in which the user starts the nail app 600 and, under the control of the nail app 600, the print engine 155 prints nail art on a nail inserted into the print target insertion section 158.

First, the user starts the nail app 600. In S701, the display control unit 610 causes the display unit 108 to display the selection screen 201 shown in FIG. 2. The nail art data displayed here is stored in advance by the nail app 600 in a multi-layered structure depending on the type of nail art. The nail app 600 may also separate the nail art data into a multi-layered structure. The types of nail art are classified into designs with only a single color, designs with patterns or patterns, and designs with 3D data. Note that single-color designs do not fall under the category of data stored in a multi-layered structure. Designs with patterns or patterns are separated into a layer that includes data on the pattern or pattern and a base layer that does not include data on the pattern or pattern in order to prevent parts of the pattern or pattern from being missing, and the amount of overflow is adjusted for each layer. The process of adjusting the amount of overflow for each layer will be described later.

Figures 8(a) and 8(b) are examples of designs including patterns and patterns, and the nail image data is stored in a two-layer hierarchy. Figure 8(a) is an example of nail image data of a design including patterns and patterns, and Figure 8(b) shows an example of storing Figure 8(a) in a two-layer hierarchy. The first layer 800 is a layer that stores data that is the base of the nail image data, that is, design data that is monochromatic and does not include patterns or patterns. The second layer 801 is a layer that stores 2D design data that includes patterns and patterns. Figure 9(a) shows an example of nail image data of a design including 3D data. Figure 9(b) shows an example of storing Figure 9(a) in a three-layer hierarchy. The first layer 800 is a layer that stores data that is the base of the nail image data, that is, design data that is monochromatic and does not include patterns or patterns. The second layer 801 is a layer that stores 2D design data that includes patterns and patterns. The third layer 900 is a layer that stores design data that includes 3D data. Furthermore, the third layer 900 holds the 3D data 901 shown in FIG. 9(c) and the adhesive surface area 902 of the 3D data shown in FIG. 9(d). The adjustment of the overhang amount for each layer will be explained when reflecting the setting data in S717.

In S702, the user selects one or more nail art data 203 to be printed on the nail art data selection screen 201. The nail art data selection receiving unit 611 receives the user's selection of one or more nail art data 203 via the nail art data display area 202 of the nail art data selection screen 201. When the user presses the confirm button 204 after selecting one or more nail art data 203, the display control unit 610 detects the press and causes the display unit 108 to display the nail image data setting screen 501 shown in FIG. 5.

The nail art data display area 502 of the nail image data setting screen 501 displays one or more nail art data 203 selected by the user in S702. In S703, the user selects one nail art data from the nail art data displayed in the nail art data display area 502. In S704, the nail image data setting unit 612 sets the nail image data included in the nail art data selected in S703 to the nail area 508.

After that, when the user presses the setting completion button 507, the display control unit 610 detects the pressing and causes the display unit 108 to display the print data creation screen 301 shown in FIG. 3. At this time, the setting data display area 302 of the print data creation screen 301 displays the setting data, which is one or more nail image data set in S704.

If printer 151 is not registered, nail app 600 executes a search process to search for a printer that can communicate with nail app 600. After executing this search process, display control unit 610 causes display unit 108 to display a list of printers that can communicate with nail app 600 as the search results. When the printer list is displayed on display unit 108, in S705, the user specifies the printer to be used from the list. Note that it is assumed here that the user specifies printer 151. Then, display control unit 610 accepts an instruction from the user to specify printer 151.

In S706, the photographing instruction unit 613 executes communication processing for the selected printer 151 and instructs the printer 151 to photograph using the photographing unit 157. Note that in S706, the photographing instruction unit 613 may transmit a camera start-up job to the printer 151, and in response to receiving this camera start-up job, the printer 151 may start up the photographing unit 157 and begin photographing.

In S707, the printer 151 transmits the moving image captured by the image capture unit 157 to the information processing device 101. This moving image is displayed in the preview area 307 of the print data creation screen 301 shown in FIG. 3. The moving image captured by the image capture unit 157 is displayed in the preview area 307 almost in real time. When the user's hand is inserted into the print object insertion unit 158, the preview area 307 displays a moving image of the user's fingertip inserted into the print object insertion unit 158.

In S708, the user selects one piece of setting data to be printed on the nail from the setting data displayed in the setting data display area 302. In S709, the nail art data selection receiving unit 611 receives an instruction from the user to select one piece of setting data. The display control unit 610 highlights the setting data selected by the user.

In S710, the user inserts the user's hand into the print object insertion section 158 provided in the printer 151 that will perform printing. At this time, in order to print the nail image data set in S708 more vividly, a gel-like liquid is applied to the user's nails in advance. Hereinafter, this liquid is referred to as the base coat. There are multiple colors for this base coat, such as white and translucent. In addition, the image display control section 614 may display a message prompting the user to insert the hand into the printer 151 at a timing after S709. After the application of the base coat, in order to prevent ink from adhering to the skin when printing is performed in S722, which will be described later, a skin protective agent liquid is applied around the user's nails in advance. Hereinafter, this liquid is referred to as the protective agent. The color of this protective agent may be any color different from that of the base coat. The reason for this will be described later in the nail detection and protective agent detection in S716.

In S711, the user sets the print area 309 while the video image started to be transmitted in S707 is displayed in the preview area 307. Specifically, the user presses the print area setting button 308. In the nail detection in S716 described later, the nail detection unit 615 automatically displays a display item indicating the print area 309 in the preview area 307 in response to pressing the print area setting button 308. In this embodiment, the number of print areas 309 that can be set is set to a predetermined value in advance. For example, in the case shown in FIG. 3, since the number of nails corresponds to the number of nails of the index finger, middle finger, ring finger, and little finger of one hand, the predetermined value is set to "4". This predetermined value corresponds to the number of rails mounted on the print object insertion unit 158 and the number of nail image data included in the setting data. In the following, a form in which the user sets the same number of print areas 309 as this predetermined value, that is, a form in which four print areas 309 are set, is described as an example. The number of print areas 309 set here is stored in the RAM 105 as a first predetermined value. That is, in this example, the first predetermined value is "4."

In S712, the photography instruction unit 613 transmits a photography instruction to the printer 151 to capture a still image. The photography instruction transmitted to the printer 151 also includes the rail number corresponding to the nail to be photographed. For example, if the four rails are numbered 1 to 4 from the left, the number "1" is transmitted when photographing the little finger of the left hand, the number "4" is transmitted when photographing the index finger of the left hand, the number "1" is transmitted when photographing the index finger of the right hand, and the number "4" is transmitted when photographing the little finger of the right hand.

In S713, the printer 151 raises the rail corresponding to the received rail number and adjusts the height of the nail so that it is close to the recording head of the printer 151. By adjusting the height of the nail to a height close to the recording head, if it is an inkjet printer, ink droplets ejected from the recording head can be reliably landed on the nail. A movable laser sensor mounted on the printer 151 is used for height adjustment. The laser sensor is installed at a height close to the recording head, and the height of the nail is raised to the maximum height where the laser is not blocked. In adjusting the height of the nail, it is more efficient to narrow the movable range of the laser sensor to the range of the nail after grasping the approximate position of the nail than to determine the movable range of the laser sensor based on the entire finger. Therefore, before adjusting the height of the nail, nail detection may be performed in advance, and the nail position information may be sent from the nail app 600 to the printer 151 together with the shooting instruction in S712. In this embodiment, such advance nail detection is called pre-nail detection. When performing pre-nail detection, the nail app 600 sends a shooting instruction to the printer 151 before S712. Since the nail height is not adjusted in pre-nail detection, the image capture instruction sent for pre-nail detection does not need to include the rail number described above. Upon receiving the image capture instruction, the printer 151 captures a still image with the image capture unit 157. When the still image capture is completed, the printer 151 transmits the captured image to the information processing device 101. The nail app 600 detects the nails from the received captured image and stores information indicating the positions of all detected nails (nail position information). Then, when issuing an image capture instruction in S712, the nail app 600 transmits nail position information of the nail to be captured together with the rail number to the printer 151. The printer 151 adjusts the height of the target nail by narrowing the movable range of the laser sensor using the received nail position information of the nail.

When the claw height adjustment is complete, in S714, the image capture unit 157 captures a still image. When the image capture is complete, the printer 151 returns the height of the target rail to the initial value, and in S715, the printer 151 transmits the captured image data to the information processing device 101.

In S716, the nail app 600 detects the nail area and the protective agent area from the received captured image. The print area 309 of the print data creation screen 301 is set from the nail area and protective agent area detected in S716. One method of detecting nails is to detect the white color of the base coat applied to the nail by image processing. Specifically, pixels exceeding a predetermined threshold value (e.g., R>200, G>200, B>200) are detected from the RGB values of the captured image, and the detected pixels are determined to be pixels of the nail area. In order to prevent the rail under the finger from being erroneously detected as a nail during nail detection, the rail is made of a color other than white, such as black. In addition, in order to prevent erroneous detection of whiteout parts of the captured image due to light reflection, for example, the rail is made of a material that diffuses light. In addition, since detection by image processing is difficult when the base coat is translucent, machine learning may be used as another detection method. By using finger images including nails coated with a white or translucent base coat as images to be trained by machine learning, it becomes possible to detect nail regions even when the base coat is not only white but also translucent. In machine learning, a learning model is constructed by learning where the nails are in the prepared training images. The constructed learning model is incorporated into the nail app 600, processed by the CPU 103 and the GPU 110, and used to detect nail regions from captured images. Since skin color and nail shape vary from person to person, by preparing many hand patterns in the training images and training them, it becomes possible to detect all kinds of nails. There are many frameworks for machine learning, and machine learning can be realized by using existing frameworks. In addition, as one method of detecting a protective agent, there is a method of detecting the color of a skin protective agent applied around the nail by image processing. Specifically, it is the same as the above-mentioned nail detection method. However, in the above-mentioned nail detection, when the white color of the base coat applied to the nail is detected by image processing, the color of the skin protective agent is a color other than white in order to distinguish the nail region from the protective agent region. In addition, when the color of the skin protective agent is translucent, machine learning may be used. Furthermore, if skin protective agent detection is not performed, the skin protective agent area may be determined based on a preset threshold value. Depending on the nail area and protective agent area detected in S716, the amount of overflow is limited in S717, which will be described later.

The processes from S712 to S716 are repeated for the number of nails to be photographed. For example, if the four nails from the pinky finger to the index finger of the left hand are to be photographed, the process of lifting the finger, photographing, sending the photographed data, and detecting the nail and protective agent is repeated for each finger. In this case, a total of four images are photographed.

In S717, when setting the print area 309, the print area setting unit 616 cuts out the part of each captured image in which the target nail is captured, and displays it in the preview area 307. In other words, the four cut-out finger images are displayed side by side in the preview area 307, and the print area 309 is set on the nail area of each finger image. Furthermore, the nail app 600 adjusts the amount of overhang depending on the nail area and protective agent area detected in S716.

FIG. 10 is a flowchart showing a process for generating overflow amount adjustment data. The process of FIG. 10 is performed by the CPU 103 of the information processing device 101 expanding the program code stored in the ROM 104 or the external storage device 106 into the RAM 105 and executing it. In S1001, the nail application 600 determines whether the nail image data included in the nail art data selected in S703 is data with a hierarchical structure. If it is determined that the data is not hierarchically structured, nothing is done, and in S1007, the nail application 600 replaces the data as setting data. If it is determined that the data is hierarchically structured, in S1002, the nail application 600 sets the overflow amount of the first layer 800 to yes. Here, setting the overflow amount to yes means setting the first layer 800 to a value larger than the nail area detected in S716 and smaller so as not to reach the protective agent area detected in S716. Furthermore, by limiting the area to be covered by the protective agent detected in S716, it is possible to prevent the ink from coming into contact with the skin.

Next, in S1003, the nail app 600 sets the overhang amount of the second layer 801 to none. Since the second layer 801 is 2D design data including patterns and designs, by setting the overhang amount to none, it is possible to prevent the patterns and designs from being missing. Next, in S1004, the nail app 600 determines whether the nail image data holds the third layer 900. If it is determined that the third layer 900 is not held, in S1006, the nail app 600 combines the first layer 800 and the second layer 801, and in S1007, replaces the combined data as the setting data. On the other hand, if it is determined that the third layer 900 is held, in S1005, the nail app 600 sets the adhesive surface area 902 of the 3D data to be smaller than the nail area detected in S716. Then, in S1006, the nail app 600 combines the first layer 800, the second layer 801, and the third layer 802, and in S1007, replaces the combined data as the setting data.

After the print area 309 is set by the print area setting unit 616, in S717, the reflection data receiving unit 617 associates the nail image data set as the setting data with the set print area 309. The reflection execution unit 618 then reflects the setting data in the print area 309 based on this association. In the case shown in FIG. 3, a correspondence is created between each of the four types of nail image data included in the setting data 302c and each of the four set print areas 309.

In S718, the user edits the print area 309 as necessary. Specifically, when the user selects the finger for which the user wants to edit the preview area 307, the screen transitions to the nail image data editing screen 1101 shown in FIG. 11, and each layer of the nail image data of the selected finger can be edited. The user selects the display/hide button 1106 of the layer to be displayed. Next, the user selects the edit execution button 1105 of the layer for which the user wants to edit, and the nail image data of the selected layer is displayed in the setting data editing area 1103. The user can adjust the size of the nail image data of the displayed layer. However, editing in each layer can be performed under the above-mentioned restrictions. For example, in the first layer, adjustment is possible within a range larger than the nail area detected in S716 and not reaching the protective agent area detected in S716. In the second layer, adjustment is possible within a range smaller than the nail area detected in S716. In the third layer, the adhesive surface area 902 of the 3D data can be adjusted within a range smaller than the nail area detected in S716. At this time, the edits are accepted by the reflection data acceptance unit 617, and the edit results are reflected by the reflection execution unit 618.

In S719, the user presses the print button 310. In response to the pressing of the print button 310, the print instruction unit 619 creates print data for printing an image in which the setting data selected by the user from the setting data displayed in the setting data display area 302 is reflected in the print area 309. Specifically, the user reflects the setting data selected by the user from the setting data displayed in the setting data display area 302 in the print area 309, and after checking the displayed content, the user presses the print button 310. The print instruction unit 619 generates print data in response to the pressing of the print button 310. At this time, the nail app 600 may display a message to the effect that "Please do not move the hand inserted in the print target insertion section 158."

In S720, the nail app 600 sends the generated print data to the printer 151. In S718, the nail app 600 sends the print data generated in S719 to the printer 151. Note that this print data reflects the print area 309 set on the screen shown in FIG. 3. For example, in the print data, the position and size of the image to be printed on the nail correspond to the position and size of the print area 309 set in FIG. 3. Therefore, in S722, which will be described later, the printer 151 prints on the part of the finger that corresponds to the print area 309.

In S721, the printer 151 raises the rail to the same height as when the rail was raised in S713. This resets the position of the nail to a position suitable for printing. In S722, the printer 151 performs printing based on the transmitted print data. As a result of S722, the nail art represented by the nail image data is printed on the user's nail. The processes from S720 to S722 are repeated as many times as the number of nails to be printed. For example, when the four nails from the little finger to the index finger of the left hand are the targets, the process of transmitting print data, raising the finger, and printing is repeated for each finger. Note that the printer 151 continues to photograph the nails during printing, and may stop printing if it detects that the hand has left the print object insertion section 158 of the printer 151 before printing is completed. Also, the nail app 600 may detect that the hand has left the print object insertion section 158 of the printer 151 before printing is completed, and the nail app 600 may instruct the printer 151 to stop printing.

As described above, according to this embodiment, even when the printing area is a small area with large individual differences, such as the nails of each finger, it is possible to adjust the amount of overflow for each layer of data. This makes it possible to prevent parts of the print data from being lost, improving printing accuracy.

In this embodiment, the printer 151 is described as an example in which one hand is inserted into the print object insertion section 158, but this is not limited to this. For example, it may be a printer installed in a store or the like in which both hands are inserted into the print object insertion section 158. In this case, the GUI operation of the nail app may be performed by a store clerk or the like. In addition, in this embodiment, an example of printing an image (pattern) as nail art has been mainly described, but a structure including a pattern may be formed as nail art using shape data and image data indicating a three-dimensional structure or the like. In addition, in this embodiment, a form in which a hand is inserted into the print object insertion section 158 of the printer 151 and printing is performed directly on the nail has been described, but another form may be used. For example, this embodiment can be applied when printing is performed using a printer that prints objects to be attached to the nail, such as stickers. In addition, in this embodiment, the fingernails have been described as an example of the detection target, but something other than the fingernails may be used as the detection target.
