When the "setting" button 440 is pressed, various settings for using the hair chart service can be performed.

A-2-1. Processing to register customer information:
When "customer" 410 is selected on the display screen, control unit 310 of stylist terminal 300 executes processing for registering customer information. Specifically, control unit 310 causes display unit 330 to display a customer information screen (FIG. 4A). The customer information screen includes a “search field” 412 , a “new registration field” 414 and a “list display field” 416 .

The "search field" 412 allows the entry of keywords (specific information (carte number), name, etc. for each customer), and the control unit 310 transmits the keywords to the management server 100. Based on the received keyword, control unit 110 of management server 100 searches for specific hair chart information from a plurality of hair chart information registered in hair chart information DB 121 and transmits the specific hair chart information to stylist terminal 300 . Control unit 310 of stylist terminal 300 displays the received specific hair chart information on display unit 330 . The hair chart information includes, in addition to the customer information described below, still image data groups of already registered hairstyles and the like.

When the "new registration field" 414 is selected, the control unit 310 causes the display unit 330 to display a customer information input screen (Fig. 4(B)). On the customer information input screen, specific information (name, age, contact information, address, birthday, etc.) of the customer P and the name of the stylist in charge can be input.

When a finger touching the "list display field" 416 is slid up and down, different customer information is sequentially displayed. Customer information newly registered in the hair chart information DB 121 in the “new registration column” 414 is also displayed in the “list display column” 416 .

When specific customer information is selected from a plurality of pieces of customer information M1 to M3 displayed in the “list display column” 416, the control unit 310 causes the chart display screen (FIG. 4(C)) to be displayed on the display unit 330. indicate. The full length of the chart display screen is longer than the display unit 330, and a part of the chart display screen is displayed on the display unit 330. The stylist Q can scroll the chart display screen in the vertical direction. can see the whole Further, FIG. 4C shows a state when the customer information M1 is selected. The chart display screen includes an “image display column” 413 , a “classification designation column” 415 and a “MEMO column” 417 .

The "image display column" 415 is a column for photographing the hairstyle of the customer P to obtain a still image data group for rotating display, and rotating the hairstyle based on the still image data group. . The still image data group is a collection of a plurality of still image data obtained by photographing the hairstyle of the customer P from a plurality of rotation angles different from each other. A plurality of rotation angles are angles obtained by equally dividing 360 degrees at predetermined imaging angle intervals. In this embodiment, the imaging angle interval is 30 degrees, and the plurality of rotation angles are 0 degrees, 30 degrees, 60 degrees, 90 degrees, 120 degrees, 150 degrees, 180 degrees, 210 degrees, 240 degrees, and 270 degrees. , 300 degrees and 330 degrees.

A plurality of still image data groups can be registered in the "image display column" 415. For example, as shown in FIG. 4C, for the same customer P (M1), still image data groups of two stages of hairstyle M1a at the time of finishing and hairstyle M1b in the middle of cutting are obtained. can be registered. It should be noted that a plurality of hairstyles displayed in the “image display field” 415 may be configured to be capable of performing interlocking rotation, which will be described later. Thereby, two-stage hairstyles can be checked from 360 degrees at the same time.

The method for acquiring the still image data group is as follows. When the camera mark 413a in the "image display column" 415 is pressed, the control unit 310 of the stylist terminal 300 displays the image capturing screen (FIG. 6) on the display unit 330 based on the image capturing instruction, and executes image capturing processing. do. FIG. 5 is a flowchart showing the details of the shooting process, and FIG. 6 is an explanatory diagram showing an example of a shooting screen. As shown in FIG. 6, the shooting screen includes an image display section 450 displaying an image of a subject and a mode switching section 460 . A mode switching unit 460 can select between a manual mode and an automatic mode.

Manual mode is a mode in which still image data groups are acquired by manually photographing a subject from a plurality of different rotation angles. As shown in FIG. 5, control unit 310 determines whether the manual mode is selected (S110). When the manual mode is selected (S110: YES), control unit 310 causes display unit 330 to display a manual mode screen (FIG. 6A). The manual mode screen includes a shooting instruction button 470 and a display of the number of shots. Next, control unit 310 determines whether or not there is a shooting instruction (S120). Control unit 310 determines that there is a shooting instruction based on pressing of shooting instruction button 470 . The control unit 310 waits until there is a photographing instruction (S120: NO), and when determining that there is a photographing instruction (S120: YES), executes manual photographing processing (S130). In the manual shooting process, control unit 310 shoots an image displayed on image display unit 450 to generate still image data, and adds 1 to the number of shots. Next, when the control unit 310 determines that the number of shots has not reached a predetermined number (for example, 12) (S140: NO), the process returns to S120. On the other hand, when the control unit 310 determines that the number of shots has reached the predetermined specified number (S140: YES), the process proceeds to S180.

Specifically, in the manual mode, for example, the stylist Q displays the image of the hairstyle of the customer P (M1) on the image display unit 450 and presses the shooting instruction button 470 as shown in FIG. Then, still image data photographed from one rotation angle (in the example of FIG. 10, front view still image data with a rotation angle of 0 degree) is generated. Thereafter, similarly, the stylist Q shoots the hairstyle of the customer P at each rotation angle of 30 degrees, and when the number of shots reaches 12, still image data of 12 hairstyles are generated at 30-degree intervals. be done.

The automatic mode is a mode in which a group of still image data is acquired by automatically photographing the subject from a plurality of different rotation angles. As shown in FIG. 5, when the automatic mode is selected (S110: NO and S150: YES), control unit 310 causes display unit 330 to display the automatic mode screen (FIG. 6B). to display. A mark recognition section 480 is included in the automatic mode screen. The control unit 310 determines whether or not the trigger pattern 522 (for example, a star mark) is recognized (S160). Specifically, control unit 310 performs image processing on the image captured by mark recognition unit 480 to determine whether or not trigger design 522 is captured within a predetermined magnification range. For example, when the image captured by the mark recognition unit 480 does not include the trigger pattern 522, or when the image captured by the mark recognition unit 480 includes the trigger pattern 522 outside the predetermined magnification range. If there is (S160: NO), the control unit 310 returns to the process of S150 and does not start the automatic photographing process. On the other hand, if the trigger pattern 522 included in the image picked up by the mark recognition unit 480 is within the predetermined magnification range (S160: YES), the control unit 310 starts automatic shooting processing ( S170). As a result, it is possible to suppress photographing at a magnification that makes it difficult to check the hairstyle of the customer P, and to suppress variation in photographing magnification of a plurality of still images photographed at a plurality of rotation angles.

In the automatic photographing process, for example, techniques disclosed in Japanese Patent No. 6712729 and Japanese Patent Application Laid-Open No. 2021-61536 can be used. A photographing method by automatic photographing processing can be expressed, for example, as follows.
"A photographing method for photographing a subject from a plurality of rotation angles different from each other,
It has a ring-shaped body, and a plurality of triager patterns serving as triggers for photographing timing of a photographing device (stylist terminal 300, etc.) are formed on the outer peripheral surface of the ring-shaped body at intervals in the circumferential direction of the ring-shaped body. arranging the photographing kit such that the subject is located on the inner peripheral side of the annular body;
a step of arranging the photographing device at a position capable of photographing the subject and at least part of the outer peripheral surface of the photographing kit;
a step of integrally rotating the subject and the imaging kit relative to the imaging device;
During the relative rotation of the subject and the imaging kit with respect to the imaging device, the imaging device shoots based on the timing of detecting that the trigger pattern is positioned at a predetermined position within the imaging range of the imaging device. and
including. ”

A cloth 500 for rotating photographing is used when the automatic photographing process of the present embodiment is executed. The cloth 500 is an example of the imaging kit. FIG. 7 is an explanatory diagram showing the side construction of the cloth 500, and FIG. 8 is an explanatory diagram showing the top construction of the cloth 500. As shown in FIG. As shown in FIGS. 7 and 8, the cloth 500 has a holding portion 510, an annular body 520, and a connecting portion 530. As shown in FIGS.

The annular body 520 has a size that can be arranged so as to surround the customer P's torso. A plurality of (for example, 12) trigger patterns 522 are shown on the outer peripheral surface of the annular body 520 at equal intervals (rotation angle intervals of 30 degrees) in the circumferential direction of the annular body 520 . Note that one of the plurality of trigger patterns 522 is a star mark (not shown) that serves as a trigger for starting automatic shooting. The holding part 510 is a belt-like body surrounding the circumference of the neck of the customer P, and is detachably held on the circumference of the neck. Note that the diameter of the holding portion 510 is smaller than the diameter of the annular body 520 .

The connecting portion 530 is a portion that connects the holding portion 510 and the annular body 520 . The connection part 530 has, for example, a sheet 532 and a plurality of core members 534 . The sheet 532 is a sheet material (for example, vinyl, cloth, cotton, etc.) that connects the holding portion 510 and the annular body 520 . With this sheet 532, for example, it is possible to prevent hair that has been cut during hair cutting, hair coloring agent, or the like from adhering to the customer's P clothes. The plurality of core members 534 are rod-shaped members arranged on the inner peripheral surface of the seat 532 or inside the seat 532 and extending from the holding portion 510 toward the annular body 520 . The core material 534 can stabilize the shape of the sheet 532 . The core material 534 is made of, for example, a flexible material (resin material or the like).

A pair of openings 560 are formed in the connecting portion 530 . A pair of openings 560 are arranged symmetrically with respect to the holding portion 510 (see FIG. 8). Here, if the connecting portion 530 were not formed with the opening 560, the connecting portion 530 would interfere with the shoulder of the customer P, and the cloth 500 would not be able to take the conical posture as shown in FIG. , the annular body 520 may be deformed, and the multiple trigger patterns 522 may not be arranged around the customer P at regular intervals. On the other hand, in the cloth 500, since the connecting portion 530 has a pair of openings 560, the connecting portion 530 is prevented from interfering with the shoulder of the customer P. As a result, the plurality of trigger patterns 522 can be evenly spaced around the customer P.

Specifically, in the automatic mode, for example, as shown in FIG. 7, the customer P is made to wear a cloth 500 and sit on a swivel chair. Next, stylist Q positions stylist terminal 300 at a position where trigger pattern 522 within a predetermined magnification range is displayed on mark recognition section 480, as shown in FIG. 6B. As a result, still image data photographed from one rotation angle (in the example of FIG. 10, still image data of a front view with a rotation angle of 0 degree) is automatically generated. Next, by rotating the swivel chair on which the customer P is sitting, the trigger patterns 522 displayed on the mark recognition section 480 are switched one after another. Each time the trigger pattern 522 displayed on the mark recognition section 480 is switched, still image data photographed from each rotation angle are automatically sequentially generated. As a result, still image data of 12 hairstyles are generated every 30 degrees.

In the process of S180, the control unit 310 causes the display unit 330 to display the shooting completion screen (Fig. 6(C)). The shooting completion screen includes a shooting completion button 490 and a reshooting button 495 . When the retake button 495 is pressed, the control unit 310 deletes the captured still image data and returns to the process of S110. On the other hand, when the shooting completion button 490 is pressed, the control unit 310 associates the specified number of shot still image data with the customer information as the still image data group, and transmits the data to the management server 100 (S190). End the process. Control unit 310 of management server 100 registers the received still image data group in hair chart information DB 121 in association with customer information. It should be noted that, in the photographing process, for example, when the button 410 is pressed (S150: NO), the control unit 310 ends the main photographing process.

In addition, in the "classification designation column" 415 of the chart display screen, it is possible to designate the classification item of the photographed hairstyle. Examples of classification items are the same as those of the classification designation column 422 described later. Furthermore, in the "classification designation column" 415, a "favorite" mark can be added to search for favorite hair chart information in a search target designation column 424, which will be described later. In addition, in the "category designation column" 415, the date of the next reservation of the customer P and the presence or absence of publication in the catalog can be registered. Also, in the "MEMO column" 417, for example, a photograph taken of a handwritten medical chart, a memo during cutting, or the like can be recorded. The control unit 310 also associates the classification items, the addition of the favorite mark, the reservation date, etc., and the information of the “MEMO column” 417 with the customer information and transmits them to the management server 100 .

Further, when the transfer mark 413b in the “image display field” 413 is pressed, the control unit 310 generates 360-degree rotating video data in which still images at a plurality of rotation angles are continuously reproduced based on the still image data group. , the 360-degree rotated video data or the URL of the website where the 360-degree rotated video data is recorded is transferred to the customer terminal 200 . Thereby, the customer P can see a 360-degree rotating video of his or her hairstyle by operating the customer terminal 200 .

A-2-2. Process for selecting a hairstyle from a hair catalog:
FIG. 9 is an explanatory diagram showing an example of a screen displayed on the display unit 330 of the stylist terminal 300. As shown in FIG. When "catalog" 420 is selected on the display screen, control unit 310 of stylist terminal 300 executes processing for selecting a hairstyle from the hair catalog. Specifically, the catalog search screen (FIG. 9A) is displayed on the display unit 330 . The catalog search screen is a column for searching for a favorite hairstyle from a plurality of hairstyles (hair chart information) registered in the catalog DB 122 of the management server 100 . The catalog search screen includes a category designation field 422 , a search object designation field 424 and a search button 426 .

A plurality of classification items can be designated in the classification designation field 422 . Examples of multiple classification items include:
"Hairstyle": All / Men's / Ladies / Free "Age": All / Old / Middle / Young / Child "Hair length": All / Long / Semi-long / Short "Style": All / Wave / Straight "Color" : All / Gray / Fashion / Normal

In the search target specification field 424, the search target range in the catalog DB 122 can be specified. In this embodiment, when "all" is specified, all hair chart information registered in the catalog DB 122 is searched. When "favorite" is specified, only hair chart information that has been previously registered as a favorite among the hair chart information registered in the catalog DB 122 is searched.

When the search button 426 is pressed, the control unit 310 transmits to 100 search information regarding various classification items specified in the category specification field 422 and the search target range specified in the search target specification field 424 . The control unit 110 of the management server 100 searches the catalog DB 122 for one or more pieces of hair chart information corresponding to various classification items specified in the classification specification column 422 within the search target range specified in the search target specification column 424 . do. Then, control unit 110 transmits the searched hair chart information to stylist terminal 300 .

Upon receiving the searched hair chart information, the control unit 310 of the stylist terminal 300 causes the display unit 330 to display the catalog list screen (FIG. 9(B)). The catalog list screen is a screen that displays a list of still images M of a plurality of searched hairstyles. Each hairstyle is a still image M at one rotation angle in the still image data group included in the retrieved hair chart information. In FIG. 9B, a front-view still image Ma with a rotation angle of 0 degrees is displayed. This processing is an example of display processing in the claims.

When the catalog list screen is displayed on the display unit 330, the control unit 310 executes catalog display processing. The catalog display process is a process for performing still image rotation display in which the still images M of one or more hairstyles displayed on the catalog list screen are sequentially changed to still images with different rotation angles. This process is an example of the change process in the claims. FIG. 10 is a flow chart showing the contents of the catalog display process. As shown in FIG. 10, control unit 310 determines whether or not there is a rotation instruction (S210). For example, the control unit 310 determines that there is a rotation instruction when it detects that the customer P slides the finger touching the catalog list screen in the horizontal direction. This process is an example of a first reception process in the scope of claims, and the rotation instruction is an example of a change instruction in the scope of claims. Note that the change instruction is not limited to the rotation instruction, and may be, for example, an instruction to individually specify a rotation angle (30 degrees, 90 degrees, etc.).

When the control unit 310 determines that there is a rotation instruction (S210: YES), it executes an interlocking rotation process (S220). The linked rotation process is a process for performing still image rotation display in which the still images M of a plurality of hairstyles listed on the catalog list screen are sequentially changed to still images with different rotation angles. FIG. 11 is an explanatory diagram showing an example of a screen displayed on the display unit 330 during the linked rotation process. FIG. 11B shows a state in which all the still images of a plurality of hairstyles listed on the catalog list screen are still images viewed from the front with a rotation angle of 0 degrees.

In the state of FIG. 11(b), when the customer P performs a leftward slide operation, the control unit 310 simultaneously displays the still images of the plurality of hairstyles listed on the catalog list screen toward the left side. 11(a)). When the customer P continues the slide operation in the left direction, 12 still images M are sequentially switched and displayed every 30 degrees for all hairstyles listed on the catalog list screen. Thereby, the stylist Q can collectively check all the hairstyles listed on the catalog list screen from 360 degrees counterclockwise. On the other hand, in the state of FIG. 11(b), when the customer P performs a slide operation in the right direction, the control unit 310 displays the still images of the plurality of hairstyles listed on the catalog list screen at the same time. The still image Mc (FIG. 11(c)) is changed to the hairstyle that is directed toward the user. When the customer P continues the slide operation in the right direction, 12 still images M are sequentially switched and displayed every 30 degrees for all hairstyles listed on the catalog list screen. As a result, the stylist Q can collectively check all the hairstyles listed on the catalog list screen from 360 degrees clockwise. At this time, the controller 310 functions as a display controller 311 .

The number of still images M of hairstyles displayed on the catalog list screen can be changed. For example, when stylist Q performs an operation to expand the catalog list screen portion with his index finger and thumb, control unit 310 increases the display magnification of each still image while decreasing the number of displayed catalog list screens. On the other hand, when stylist Q performs an operation to narrow the catalog list screen portion with his index finger and thumb, control unit 310 decreases the display magnification of each still image while increasing the number of displayed catalog list screens. FIG. 12 is an explanatory diagram showing an example of a screen displayed on the display unit 330 during the interlocking rotation process after the display number is changed. In FIG. 12, still images M of four hairstyles are displayed.

Here, as shown in FIG. 12, for example, when a still image of one of the four hairstyles is touched and a slide operation is performed in the horizontal direction, the control unit 310 displays the , the still images M at a plurality of rotation angles are displayed sequentially in the left-right direction. In conjunction with this, control unit 310 rotates and displays the remaining three hairstyles. This allows the stylist Q to compare the specific hairstyle with other hairstyles while rotating it 360 degrees.

Further, as the number of displayed catalog list screens increases, still image data groups with a plurality of rotation angles at wider angular intervals may be used for rotating display. For example, when the number of displayed catalog list screens is nine (FIG. 11), for each hairstyle, four still images M are sequentially switched and displayed every 90 degrees, and the number of displayed catalog list screens is four. In some cases (FIG. 12), for each hairstyle, eight still images M at 45-degree intervals may be sequentially switched and displayed. With such a configuration, it is possible to reduce the processing load of rotating display when the number of displayed catalog list screens is large, and when the number of displayed catalog list screens is small, a plurality of hairstyles can be enlarged while being enlarged. Detailed comparison can be made at fine angular intervals.

Further, the control unit 310 selects some (two or more) hairstyles from the still images M of three or more hairstyles displayed on the catalog list screen, and selects some of the selected hairstyles. Rotating display may be performed. This processing is an example of selection processing in the claims. For example, in FIG. 12, if the stylist Q selects, for example, two hairstyles from among the still images M of four hairstyles displayed on the catalog list screen, and then performs a horizontal slide operation, Rotation display is performed only for the two selected hairstyles. As a result, the processing load of the interlocking rotation can be reduced compared to the configuration in which all the hairstyles displayed on the catalog list screen are displayed in rotation. In this case, after the hairstyle is selected, only the still image of the selected hairstyle may be enlarged and displayed without displaying the still image of the hairstyle that was not selected. This processing is an example of magnification change processing.

When the control unit 310 determines that there is a fixation instruction (S210: NO and S230: YES), it executes partial slide processing (S240). For example, when a stylist Q designates a still image M of a favorite hairstyle from a plurality of hairstyles displayed on the catalog list screen (for example, long presses the still image M), it is determined that there is a fixed instruction, and Set a hairstyle as a fixed target. This processing is an example of designation processing in the claims.

In the partial slide process, for example, when a vertical slide operation by the stylist Q is received, the control unit 310 displays the still image M of the hairstyle to be fixed among the plurality of hairstyles displayed on the catalog list screen. , only the still image M of the hairstyle that is not fixed is switched to the still image M of another hairstyle. This process is an example of the second acceptance process and the switching process in the scope of claims.

FIG. 13 is an explanatory diagram showing an example of a screen displayed on the display unit 330 during partial slide processing. In FIG. 13B, it is assumed that the hairstyle still images Ma to Md are displayed and the hairstyle still image Ma is set as a fixed target. When an upward slide operation is performed from the state of FIG. 13(B), the hairstyle still image Ma is fixedly arranged, and the hairstyle still images Mb to Md are replaced with the still images Me, Mf, etc. of different hairstyles. (FIG. 13(A)). Further, when a slide operation is performed downward from the state of FIG. It is switched to Mz, etc. (FIG. 13(C)). As a result, the stylist Q can switch and display the still image of another hairstyle while leaving the still image M of the hairstyle that he likes, and search for the hairstyle that he likes more. In the example of FIG. 13, when the maximum number (four) of fixed objects to be displayed on the catalog list screen is specified, all the still images M of hairstyles displayed on the catalog list screen are fixedly arranged, and the slide operation is performed. may be disabled. Note that if a rotation instruction is given after the partial slide processing (S210: YES), all the hairstyles displayed on the catalog list screen are also subjected to the interlocking rotation processing.

The control unit 310 determines whether or not there is a hairstyle determination in the process of the interlocking rotation process, the partial slide process, etc. (S250). Deciding on a hairstyle means deciding on one hairstyle. For example, when the stylist Q double-touches (double-presses) the still image M of the hairstyle that she likes, the control unit 310 determines that the hairstyle has been determined (S250: YES), and only the still image M of that hairstyle is displayed. is displayed on the display unit 330 (S260). FIG. 14 is an explanatory diagram showing the independent display screen. As shown in FIG. 14, the stylist When the slide operation in the left-right direction is performed by Q, the control unit 310 moves the still images M at a plurality of rotation angles (for example, 12) for the hairstyle displayed on the single display screen to any one of the left-right directions. Rotating display is performed to display sequentially in the order of .
