Description

  The present invention relates to a system for realizing a photograph providing service.

  A person or group going to leisure such as a trip or amusement park will take commemorative photos as appropriate. The general method of taking this commemorative photo is the so-called self-shooting method where the photographer himself / herself or his / her group is photographed, the method of requesting other people in the vicinity to shoot, or the paying around There are ways to apply for photographers' photography services.

  As another imaging method, the invention described in Patent Document 1 discloses an automatic imaging system. The subject is provided with a transmitter. For example, when the distance between the subject and the automatic photographing camera reaches a predetermined distance, the automatic photographing camera automatically photographs the subject. With this method, it is possible to obtain a photograph without the subject being conscious.

JP 2004-282769 A

  However, general imaging methods have the following problems. First, commemorative photos obtained by these methods often have a uniform pattern composition and expression. One reason for this is that the distance and angle between the photographer and the subject are substantially the same. For example, in a method in which the subject himself / herself takes a picture of himself / herself with a camera, the subject is adjusted so that himself / herself or a group of the subject enters the screen by extending the arm holding the camera. However, the adjustment range of the arm length is limited, and as a result, the composition of the photograph often occupies most of the subject and the background is slightly visible. Since the subject decides when to take a photo, it becomes a conscious photo with a prepared facial expression. On the other hand, if you ask someone else or a paid photographer, the photographer who is usually asked to hold the camera about 2 to 4 meters away from the subject who is the client, adjust the composition so that the subject falls within the angle of view. I often shoot. Many commemorative photos tend to have almost the same composition and expression just with a different background. For example, the photographer usually calls out and the subject prepares a smile to match the subject.

  Although the method of automatically photographing at a predetermined timing described in Patent Document 1 may be a photograph with various expressions instead of a conscious photograph, it is not always a good photograph for a subject. For example, in automatic shooting, when the subject is facing down or when it is not desirable as a facial expression, it often happens that the photograph does not become a desired photograph.

  Secondly, if you ask other people such as tourists around you, depending on the person, it may be troublesome to ask other people to take pictures or explain how to shoot the camera, or other people If you do not hesitate to ask them to take time, you may lose the opportunity to shoot. In order to have at least other people take a lot of commemorative photos, and to ask them to compose various photos at the composition and timing, a lot of interaction with other people is required. Furthermore, it is not realistic to ask other people to take a picture when the subject is unconscious, because it greatly restricts time.

The present invention has been made in view of the above circumstances, and requires a request to obtain photographs from various angles and photographs with natural expressions that are not conscious of being photographed, and requires interaction with others. The purpose is to provide a technology that can respond to a request to obtain a photograph taken by another person without taking it.

  The present invention relates to a system for realizing a service that mediates between a person who desires to take a picture (photographer) and a person who takes a picture (photographer). In this system, for example, the server accepts (logs in) entries of photograph applicants and photographers, notifies photographers of information relating to photograph applicants, and provides photograph photographers with photographs taken by arbitrary photographers. Etc. are performed automatically. With such a mechanism, the photograph applicant does not need to directly interact with the photographer, and can obtain his own photograph (still image or moving image image data) photographed by any photographer. Moreover, by not letting the photographer know who and when to take photos, photos of various angles, distances and angles, photos of natural expressions and natural scenes, photos with motion, etc. It can be expected that high value-added photographs can be provided. In this specification, the service is referred to as a “photo providing service”, and a system for realizing the service is referred to as a “photo providing system” or a “data system”. However, service names and system names are for convenience and are not intended to limit the scope of the invention.

  Various forms of provision of the photo providing service are assumed. For example, the service may be provided in a limited area such as an amusement park, a theme park, an event venue, or a shopping mall, or the service may be provided without limitation of the area. In addition, anyone (that is, a general person) may be allowed to enter the photographer, or restrictions may be placed on who can enter the photographer (for example, a professional photographer or a person with a predetermined qualification or license) Only become a photographer). Of course, the same person may be allowed to enter both the photograph applicant and the photographer. Alternatively, the operator of the service may prepare a photographer (for example, a staff at an amusement park becomes a photographer and photographs a visitor who desires a photograph).

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the configuration and operation of the system described in the following embodiments are merely examples, and are not intended to limit the scope of the present invention.

(Overall configuration of data system)
FIG. 1 is a diagram showing the components of the data system according to the embodiment of the present invention and their relationships. The data system includes, as components, a server 1, a user device 3 and a photographer device 6 that can communicate with the server 1 via a network, and a camera 8.

  The server 1 is a device that provides a photo providing service that mediates between the photograph applicant 2 and the photographer (photo provider) 5. The server 1 is configured by a general-purpose server computer having a processor, a memory, a storage, a communication unit, and the like. The server 1 may be composed of one computer or a plurality of computers. A program related to the photo providing service is installed in the server 1, and various functions related to the photo providing service to be described later are realized by the processor executing the program.

  The user device 3 is a device possessed and operated by a photograph applicant 2 who is a user (user) of a photograph providing service. The user device 3 includes a processor, a memory, a storage, a display unit, an input operation unit, a position information receiving unit that can acquire position information, a communication unit, and the like (all not shown). The position information receiving unit can calculate the position information of the user device 3 by receiving a signal from a GPS (Global Positioning Systems) satellite, for example. The communication unit can communicate with the server 1 via a network. The user device 3 is preferably portable by the photograph applicant 2, for example, a smartphone, a tablet terminal, a wearable terminal, a mobile computer owned by the photograph applicant 2, or a dedicated device. Also good. User software 4 that is an application program for using the photo providing service is installed in the user device 3. When the processor executes the user software 4, various functions for using a photo providing service to be described later are realized.

  The photographer device 6 is a device possessed and operated by the photographer (or photograph provider) 5. The photographer device 6 includes a processor, a memory, a storage, a display unit, an input operation unit, a position information receiving unit that can acquire position information, a communication unit, and the like (all not shown). The position information receiving unit can calculate the position information of the photographer device 6 by receiving a signal from a GPS satellite, for example. The communication unit can communicate with the server 1 via a network. The camera 8 operated by the photographer 5 preferably has a communication function, and it is desirable that the photographer device 6 and the camera 8 can communicate with each other. The communication function between the photographer device 6 and the camera 8 may be short-range wireless communication such as Bluetooth (registered trademark), or may be wired communication such as USB. The photographer device 6 is preferably portable by the photographer 5, and may be a smartphone, a tablet terminal, a wearable terminal, a mobile computer owned by the photographer 5, or a dedicated device, for example. . The photographer device 6 is installed with photographer software 7 which is an application program for using the photograph providing service as a photographer. When the processor executes the photographer software 7, various functions for providing a photograph to the photograph providing service as a photographer are realized. The camera 8 may be a digital camera, a digital video camera (camcorder), or a camera built in an electronic device. Furthermore, the camera 8 may include a position information receiving unit and may have a function of embedding GPS information in a photograph taken. The camera 8 is possessed and operated by the photographer 5. The photographer device 6 and the camera 8 may be separate hardware or integrated. For example, by installing the photographer software 7 on a smartphone or tablet terminal with a built-in camera, a device that serves as the photographer device 6 and the camera 8 can be configured.

As shown in FIG. 2, the server 1 can communicate with a plurality of user devices 3 and a plurality of photographer devices 6, respectively. Each user device 3 is usually owned and operated by a different photographer. Each photographer device 6 is usually owned and operated by a different photographer. Each photographer device 6 is preferably communicable with a camera 8 that is normally owned and operated by each photographer.

(Photo service flow)
Next, an outline flow of the photo providing service will be described. FIG. 3 is a diagram showing data and an operation flow of this embodiment. Note that the user software 4 installed on the user device 3 and the photographer software 7 installed on the photographer device 6 are based on the assumption that initial setup described later has been completed.

  First, the user device 3 possessed by the photograph applicant 2 transmits the subject information to the server 1 together with the time stamp and ID information that can identify the photograph applicant 2 (step S101). In parallel with receiving and logging this information, the server 1 transmits subject information to the photographer device 6 possessed by the photographer 5 (step S102). The subject information is information for letting the photographer 5 know that the photograph applicant 2 wants to take a photograph. For example, the user information of the photograph applicant 2 and the photograph applicant 2 It is the information containing the positional information on. The received subject information is displayed on the display unit of the photographer device 6 (step S103). Based on the displayed subject information, the photographer 5 searches for a corresponding real photograph applicant 2 in the real world and takes a picture of the photograph photographer 2 with the camera 8 (step S104). The photograph data (image data) is transferred from the camera 8 to the photographer device 6 using a communication function provided in the camera 8 and the photographer device 6 (step S105). Subsequently, the photographer device 6 transfers the photograph data and the photographer 5 ID information to the server 1 via the network (step S106). The server 1 identifies the subject in the photo data transferred from the photographer device 6 (step S107). As this specifying method, for example, a method of matching a photograph photographing position (for example, position information acquired by the photographer device 6 or the camera 8) and the position of the photograph applicant 2, and who the photographer 5 photographed And a method for identifying a subject by face recognition processing. The server 1 can provide the photograph data in which the subject is specified to the user device 3 of the subject (step S108). The provision enabling includes transmission of photo data or thumbnails thereof, transmission of a URI (Universal Resource Identifier) of photo data, registration of photo data in a cloud storage, and the like. In this way, the photograph applicant 2 can obtain the photograph of himself (photographer 2) taken by any photographer 5 who is another person without contact with the photographer 5 or interaction. The subject information transmitted from the server 1 to the photographer device 6 or displayed by the photographer device 6 is preferably limited to information necessary for the photographer 5 to find the photograph applicant 2. Thereby, it is possible to protect the unnecessary personal information of the photograph applicant 2 from being leaked to the photographer 5, and the photograph applicant 2 receives the photography / providing service while maintaining anonymity with respect to the photographer 5. be able to. For example, the photographer 5 may simply display the position information of the photograph applicant 2 on the photographer device 6 in order to find the photograph applicant 2. The user ID of the photograph applicant 2 and other information are stored in the photographer 5. There is no need to let them know or display on the photographer device 6.

<First embodiment>
Subsequently, the first embodiment of the present invention will be described in more detail. FIGS. 4 and 5 are diagrams showing setup and preparation operations required on the photograph applicant 2 side and the photographer 5 side, respectively, for carrying out the first embodiment of the present invention.

(Setup for photo applicants)
FIG. 4 is a diagram showing the setup and preparation operations on the photograph applicant 2 side. First, the photograph applicant 2 downloads and installs the user software 4 on the user device 3 (step S201). The user software 4 can be downloaded from the server 1 or a predetermined download site. Subsequently, the photograph applicant 2 activates the installed user software 4 (step S202), and inputs user information (step S203). The user information is account information of the photograph applicant 2 and includes, for example, the user account name and password of the photograph applicant 2. User information includes name, address, e-mail address, SNS account, payment method for photo purchase, and feature information indicating appearance characteristics of photograph applicant 2 (for example, photo, face image, personal belongings and clothes information) ) Or the like. It is preferable that the photograph applicant 2 can register a desired payment method from a plurality of payment methods such as credit card, bank withdrawal, prepaid, electronic money, and point payment. The user device 3 transmits the input user information to the server 1, and the server 1 records the user information in a database in the storage (step S204).

  Once this procedure is performed, the photograph applicant 2 can log in to the photo providing service from the next time using a user account and password or another SNS account registered in advance. When the photograph applicant 2 performs a login operation (step S205), the user device 3 issues a login request to the server 1 (step S206), and the server 1 performs a login process (step S207). Call the user information of 2. The result of the login process is transmitted to the user device 3 (step S208), and if the login is successful, it is possible to shift to the next shooting sequence described below.

(Photographer setup)
On the other hand, FIG. 5 is a diagram showing the setup and preparation operations on the photographer 5 side. First, the photographer 5 downloads and installs the photographer software 7 on the photographer device 6 (step S211). The photographer software 7 can be downloaded from the server 1 or a predetermined download site. Subsequently, the photographer 5 activates the installed photographer software 7 (step S212), and inputs photographer information (step S213). The photographer information is account information of the photographer 5 and includes, for example, the account name and password of the photographer 5. The photographer information includes name, address, e-mail address, SNS account, information on how to receive the payment such as the sales price of the photograph and photographing reward, and feature information indicating the appearance characteristics of the photographer 2 (for example, photograph, face image) , Information on personal belongings and clothes), and information on the photographing equipment and photographing style of the photographer 2 may be included. It is preferable that the photographer 5 can register a desired method from a plurality of consideration receiving methods such as bank transfer, electronic money, and points. The photographer device 6 transmits the inputted photographer information to the server 1, and the server 1 records the photographer information in the database in the storage (step S214).

  Once this procedure is performed, the photographer 5 can log in to the photo providing service from the next time with the photographer account and password or another SNS account registered in advance. When the photographer 5 performs a login operation (step S215), the photographer device 6 issues a login request to the server 1 (step S216), the server 1 performs a login process (step S217), and the photographer 5 Call the photographer's information. The result of the login process is transmitted to the photographer device 6 (step S218), and if the login is successful, it is possible to shift to the next imaging sequence described below.

The server 1 may assign a unique user ID to each photograph applicant 2 and manage the photograph applicant 2 based on this ID information. Further, the server 1 may assign a unique photographer ID to each photographer 5 and manage the photographer 5 based on this ID information. For example, when new user information or new photographer information is registered in the server 1, the server 1 issues a unique ID, which is used to manage various information, identify the photograph applicant 2, and photographer 5. It is good to use for identification. ID information such as user ID and photographer ID is also managed as account information of each person.

(Shooting sequence)
FIG. 6 is a diagram showing a detailed photographing sequence according to the first embodiment of the present invention. The photographer 5 performs a transmission operation of photographer position information and photographer ID information on the photographer device 6 while the photographer device 6 is logged in to the server 1 (step S301). This operation is desirably performed when the photographer 5 is ready to take a photograph of an arbitrary subject. Next, the photographer ID information and the photographer position information are transferred from the photographer device 6 to the server 1, and the server 1 starts recording the position information for each photographer (step S302). Thereafter, the photographer position information is periodically transmitted from the photographer device 6 to the server 1 and logged by the server 1. The photographer position information may include time, latitude, and longitude information calculated by the photographer device 6 receiving signals from a plurality of GPS satellites, for example. The photographer device 6 starts communication with the camera 8 possessed by the photographer 5 (step S303). Note that the communication connection between the photographer device 6 and the camera 8 does not have to be at this timing. For example, a connection may be made periodically, or a connection may be made before and after shooting with the camera 8.

  On the other hand, the photograph applicant 2 starts an operation to start transmitting the position information of the photograph applicant 2 as subject information together with the time stamp and the user ID information on the user device 3 while the user device 3 is logged into the server 1. This is performed (step S304). This operation is desirably performed when the photograph applicant 2 wants another person to take a photograph through this service. The user software 4 may have a function that can manually turn off transmission of user position information. If this function is used, when the photograph applicant 2 does not want to take a picture (for example, when going to the toilet), it is possible to easily prohibit photography. Further, the user software 4 may have a function of automatically turning off the transmission of the user position information when it matches a preset condition. For example, privacy can be protected by setting in advance conditions such as a place where the photograph is not desired to be taken (around the home, around the toilet, etc.) and a time zone.

  User ID information and user position information are transferred from the user device 3 to the server 1, and the server 1 starts recording position information for each photograph applicant (step S305). Thereafter, the user position information is periodically transmitted from the user device 3 to the server 1 and logged by the server 1. The user position information may include time, latitude, and longitude information calculated by the user device 3 receiving signals from a plurality of GPS satellites, for example.

  The server 1 uses the logged user position information and photographer position information to extract the photographer 5 existing around each photograph applicant 2 (step S306), and the photographer 5 information is photographed in the periphery. It may be transmitted to the user device 3 as person information (step S307). Since the user device 3 can display information of the photographer 5 existing in the vicinity (step S308), the photograph applicant 2 can know whether or not there is a possibility that a photograph is taken at this place. However, if the photograph applicant 2 knows the position of the photographer 5, the photograph applicant 2 may behave unnaturally and look conscious of photographing. Therefore, the peripheral photographer information may not be distributed to the user device 3. Alternatively, the user software 4 may have a function capable of manually setting whether or not the peripheral photographer information is to be distributed (or displayed).

Note that the server 1 may distribute the position information of other photographers to the photographer device 6 of the photographer 5. Thus, the photographer 5 can know at which position the other photographer is taking a picture. For example, when it is found that there are a plurality of photographers around the user, the photographer 5 differs from the other photographers by taking measures such as moving to a place where no other photographer exists. The photograph applicant 2 can be photographed from the position. As a result, it can be expected that the photograph applicant 2 can be provided with photographs taken at various angles, distances, and angles of view.

  The server 1 may distribute information other than the photographer's position information to the user device 3. For example, a profile registered in advance by the photographer 5, a facial photograph, features, a used photographing device, and the like may be included. In this case, even if a function that enables the photograph applicant 2 to stop providing position information to the desired photographer 5 and a function that issues a photographing request to the desired photographer 5 are implemented in the user software 4. Good.

  Similarly, the server 1 uses the logged user position information and photographer position information to extract the photograph applicant 2 existing around each photographer 5 (step S309), and uses the information as peripheral subject information. To the photographer device 6 (step S310). The photographer device 6 displays the information of the photograph applicant 2 existing in the vicinity (step S311), and the photographer 5 confirms the position of the photograph applicant 2 in the vicinity of the photographer 5 by looking at the information. For example, as shown in FIG. 7, the position 12 of the photographer 5, the surrounding map 11, and the position 13 of the subject are displayed on the display unit of the photographer device 6. In this example, it can be read that the subject (photographer 2) who exists within the range of the surrounding map 11 is only the person A, and the person A is at the position 13 shown on the map. Such map information (map display) is an example of support information that assists the photographer 5 in finding the photograph applicant 2 in the real world. The output format of the support information may be a format other than the map information. For example, the support information may be output by voice.

  The mark indicating the subject position may be displayed with an icon or a photograph registered in advance by the photograph applicant 2. The icon or photo may be information indicating the appearance characteristics of the photograph applicant 2. For example, it may be a photograph of the photographer 2's face, a full-length photograph, a portrait, or information (photograph, picture, avatar, etc.) indicating what the photographer 2 has (such as a bag) or clothes. The photographer 5 may be able to recognize the real photograph applicant 2 corresponding to the icon or photograph displayed on the screen of the photographer device 6 more quickly and accurately. The photographer can more easily find the person who wants to take a photograph by using a face photograph or a whole body photograph. With clothes and avatars, it can be difficult to find, and you may miss the opportunity to shoot. The mark to be set may be determined by each photograph applicant from the viewpoint of each privacy policy and photographing opportunity, and it is desirable that the mark can be set as appropriate on the user software 4. In addition, when the photo providing service using this data system is performed within a narrow range, it is not always necessary to include position information as subject information. For example, if the photographer can recognize the corresponding photograph applicant by simply displaying the icon or photograph of the photograph applicant 2 on the photographer device 6, the service can be provided without using position information.

  Note that the server 1 has a function of automatically stopping the provision of subject information of the photograph applicant 2 to the photographing device 6 when the location where the photograph applicant 2 is present matches a preset condition. Also good. Further, the condition for stopping the provision of the subject information may be set freely by the photograph applicant 2. For example, the photograph applicant 2 can protect the privacy by setting in advance conditions such as a place where the photograph is not desired to be taken (around the home, around the toilet, etc.) and a time zone. In addition, it is preferable that the server 1 stops providing the subject information even when there is a photograph applicant 2 in an area (such as a residential area) where photographs are not generally taken.

Subsequently, the photographer 5 appropriately adjusts the angle of view and the camera lens magnification so as to include the photograph applicant 2 using the camera 8 possessed (step S312). The photographer 5 performs a shutter operation of the camera 8 at an appropriate timing, so that a photograph of the photograph applicant 2 is generated and stored in the camera 8 (step S313). The appropriate timing can be appropriately adjusted and devised by the photographer 5 so as to obtain a preferable photograph for the photograph applicant 2. For example, it is generally appropriate timing when the photograph applicant 2 is smiling, when the scenery within the angle of view is beautifully reflected, or when there is no other person around. It is.

  The photograph data photographed in this way is transferred from the camera 8 to the photographer device 6 via the communication function described above (step S314). Subsequently, this photograph data and photographer ID are transmitted from the photographer device 6 to the server 1 and stored (step S315). Here, the server 1 identifies the subject in each piece of photo data (step S316). The subject can be specified by the following method, for example. First, the server 1 uses the shooting time information included in the photo data, the photographer ID information of the photographed photograph taken at the same time, and the position information of the photographer recorded in the server 1 at each time. Confirm the position where the was shot. Subsequently, the server 1 reads out the time and position information at which the photograph was taken and the position record information at each time of all the photograph applicants 2 stored in the server 1, and requests the photograph that matches the time and position of the photograph. Person 2 is specified. In this way, each photograph and its subject can be specified.

  Here, when there are a plurality of subject candidates, for example, a method may be used in which the photograph applicant 2 present at the position closest to the photographing position of the photograph is specified as the subject. For example, in the example of FIG. 8, the person B having the log data at the position closest to the shooting position of the photograph 1 is specified as the subject among the four subject candidates of the persons A to D. Alternatively, a method may be used in which the photograph applicant 2 moving to the photographer 5 side is specified as a subject. This is because the photographer 5 is generally likely to take a picture from the front of the subject. The moving direction of the photograph applicant 2 can be calculated from time-series log data of the position information of the photograph applicant 2, for example.

  Furthermore, a method of specifying a subject by image analysis such as face recognition processing by the server 1 using a photograph registered by the photograph applicant 2 at the time of account creation is also possible. If the number of photographs and subjects handled by the system is enormous, a large computation resource and computation time are required to identify the subject by this image analysis. Therefore, even when the subject is specified by image analysis, it is preferable to perform the image analysis in a state where the position information is narrowed down to several candidates as subject candidates as described above.

  In addition, when the camera 8 has a position detection function (for example, a function of receiving a signal from a GPS satellite and calculating the position information of the camera), it may be used as the photographing position information of the photograph. If there is no communication function between the camera 8 and the photographer device 6, the photograph data may be moved from the camera 8 to the photographer device 6 using a recording medium.

  Subsequently, the subsequent processing of the specified photo data will be described. FIG. 6 shows a case where a photo trading function is provided as an example. First, sample data of each photograph is created in the server 1 (step S317). Although the sample data can confirm the contents of the photograph to be sold, it is preferable that the sample data itself is processed so as to have a low value as a commemorative photograph. For example, the image data may be reduced in quality by thinning out (low resolution image, thumbnail image), or may be one in which a watermark character such as “sample” is inserted in the image.

The server 1 transmits this sample data to the user device 3 of the photograph applicant 2 specified as the subject (step S318). The user device 3 displays the sample data on the display unit (step S319). The photograph applicant 2 confirms this sample data and determines whether or not to purchase the original data of this photograph (step S320). In the case of purchase, the photograph applicant 2 performs a photograph purchase operation (step S321), and the user device 3 transmits a purchase query to the server 1 (step S322). The server 1 performs billing processing for the photograph applicant 2 based on a preset fee payment method (step S323). When the accounting process is completed, the server 1 transmits the original photo data to the user device 3 (step S324), and the user device 3 displays the photo data so that the photo applicant 2 confirms the photo. (Step S325).

  The sales amount of a photo may be fixed, or may be set individually for each photo. Further, it is desirable that the sales amount is simultaneously transmitted in the step of transmitting the sample data to the user device 3 (step S318), and displayed on the user device 3 together with the sample data and the sales amount. Further, instead of directly transmitting the photograph data or the sample data itself from the server 1 to the user device 3, a link (for example, URL, URI) to the storage location of the photograph data or the sample data in the server 1 is transmitted from the server 1 to the user device 3. It is good also as a form transmitted to. In this case, the photograph applicant 2 can browse the photo data or sample data stored on the server 1 by operating the user device 3.

  Various functions may be implemented in the user software 4 so that the photograph applicant 2 can perform desired processing on the photograph data received by the user device 3. For example, the user software 4 may have a function of saving a photo in the user device 3 and a function of transferring to another cloud storage.

  Note that if the individual sale of the photograph is not performed, the server 1 specifies the subject corresponding to the photograph data (step S316), and then omits the above-described steps S317 to S323 and transmits the photograph data to the user device 3. (Step S321) may be performed.

  The timing of sending the photographed photo data or sample data to the subject may be any way, and each time a photograph is taken, it may be sent to the photograph applicant 2 identified as the subject in the above sequence. In addition, a form in which photographs taken at regular intervals are sent together may be used.

  On the other hand, for the photographer 5, the payment process of the reward is performed in the server 1 in accordance with a preset reward amount and a method for receiving the compensation (step S 326). The reward payment information is appropriately transmitted from the server 1 to the photographer device 6 (step S327), and the photographer 5 can confirm the reward payment information (step S328).

  Further, it is preferable that the photo sales amount and the remuneration amount can be adjusted by an operator of the system. For example, in the case of a fee system in which a fixed amount is paid regardless of how many photos the photograph applicant 2 purchases, a uniform amount may be collected from the photograph applicant 2. If the photographer 5 is provided with a fixed salary instead of a single photo, a fixed salary may be paid. The server 1 may have a function of causing the photographer 5 to set the sales amount of the photograph and the remuneration amount of the photographer. In addition, the server 1 may have a function of automatically setting or dynamically changing the sales amount of the photograph and the remuneration amount of the photographer. For example, the server 1 may prompt the photograph applicant 2 to purchase by lowering the unit price of the photo when the sales situation of the photo is lower than expected. In addition, the server 1 may set the sales price of the photo and the remuneration amount of the photographer according to the shooting location of the photo. For example, a photograph of a place that cannot be easily reached, such as the summit of Mt. Fuji, or a photograph of a facility in which an entrance fee is charged may be set at a relatively high price to increase the remuneration of the photographer. Alternatively, in order to collect or pay a fee or a reward by a system or method different from the present system, the system may not include or use a fee charging and reward payment function. Alternatively, the system may not have or be used for billing and reward payment functions in order to operate the system to provide photos for free.

  As described above, by using the system of the present embodiment, the photograph applicant 2 can obtain a photograph of the photograph applicant 2 photographed by the photographer 5 without requiring interaction with the photographer 5. The photograph applicant 2 can shoot without knowing the existence of the photographer 5 and the photographing timing, so that a natural expression, a natural scene, and a moving picture can be obtained from various angles, distances, and angles of view. Will be able to.

<Second Embodiment>
Subsequently, another embodiment of the present invention will be described. Another embodiment is an embodiment that solves a problem that occurs when the above-described first embodiment is applied to various situations. The problem is solved by changing or adding the function of the server 1 or the user software 4 or the photographer software 7. This difference is mainly achieved by changing the range indicated by X in the sequence diagram of FIG. 6 to other sequences and functions. Therefore, this difference will be described mainly.

  First, a second embodiment of the present invention will be described. For example, when operating a photo service using this system in a popular tourist destination, amusement park, or amusement park, the subject density corresponding to the photo data increases because the subject's location density is high, and the subject is identified. Can be difficult. For example, as shown in FIG. 9, there may be four photograph applicants A to D that can be photographed on the surrounding map 11 at the photographer position 12. Reference numerals 13A to 13D are icons indicating the positions of the photograph applicants A to D, respectively. Although a human figure is displayed as an icon in FIG. 9, a photographer's photograph, avatar, feature, or the like may be displayed on the icon. When the photographer 5 selects and shoots one of the four photograph applicants, the server 1 uses the photograph photographing position information and the position information of all photograph photographers, and the position information is close as a subject candidate of the photograph. The four photo applicants A to D can be narrowed down. However, it may be difficult to specify one person out of four persons within a narrow range due to problems such as accuracy of position information. In this case, a method of sending sample data of photographed photographs to all four persons is also conceivable, but this solution may be inappropriate from the viewpoint of privacy.

  The second embodiment can cope with at least this problem. FIG. 10 shows an imaging sequence according to the second embodiment of the present invention, and shows a sequence that is an alternative to the sequence of part X in FIG. 6 in the first embodiment. In order to avoid duplication of description, the description of the sequence before the portion X in FIG. 6 is omitted, and the characteristic sequence of the second embodiment will be described below.

  In the sequence immediately before the X part in FIG. 6, the position information of the photograph applicant 2 and the photographer 5 is transmitted to the server 1, and the server 1 is logging the position information. Subsequently, the server 1 extracts the photograph applicant 2 existing around the photographer 5 (step S401). Further, the server 1 transmits the extracted position information of the photograph applicant 2 as peripheral subject information to the photographer device 6 (step S402), and the photographer 5 displays the photograph applicant 2 displayed on the photographer device 6. Is confirmed (step S403). The process up to here is the same as in the first embodiment.

  Here, the photographer 5 performs an operation of selecting a subject to be photographed on the photographer device 6 (step S404). Take the case of FIG. 9 as an example. For example, when the photographer 5 selects the person A from four photograph applicants (subject candidates), the photographer 5 taps the icon 13 A of the person A shown on the touch panel display of the photographer device 6. . With such functions and operations, the photographer 5 can designate (teach) which person of the plurality of subject candidates is to be the subject. This function may be implemented in the photographer software 7. It is desirable that the photographer software 7 further includes a function that allows the photographer 5 to confirm the selected subject by highlighting the subject selected by the photographer 5.

  In this state, the photographer 5 appropriately adjusts the angle of view and the camera lens magnification so as to include the selected subject using the camera 8 possessed (step S405). The photographer 5 performs a shutter operation of the camera 8 at an appropriate timing, so that a photograph of the photograph applicant 2 as the selected subject is generated and stored in the camera 8 (step S406). The photographed photograph data is transferred from the camera 8 to the photographer device 6 via the communication function described above (step S407).

  Subsequently, when the photograph data and the photographer ID are transmitted from the photographer device 6 to the server 1, the selected subject information designated by the photographer 5 is also transmitted to the server 1 and stored (step S408). Since the subject information corresponding to the photo data has already been obtained, the server 1 does not require subject identification processing. The subsequent sequence is the same as that of the first embodiment. In the case of buying and selling photographs, the server 1 generates sample data and transmits the specified subject to the user device 3 of the subject.

  In this way, in the second embodiment of the present invention, it is possible to specify a subject (photographed photograph applicant 2) corresponding to a photograph even in a place where the photographer desires a high place density. This eliminates waste of communication traffic and processing time due to transmission of extra photos, and enables stable system operation. In addition, since it is possible to prevent a photograph taken by a certain photographer 2 as a subject from being mistakenly transmitted to another photographer, the system can be operated in consideration of privacy issues.

<Third embodiment>
Subsequently, a third embodiment of the present invention will be described. For example, when the photograph providing service is performed using the system of the above-described embodiment, the photographer 5 arbitrarily picks up a subject and shoots, so that the number of shots may vary for each photographer 2. There is sex. If you apply for this service at an amusement park and there are a person A and a person B who spent the same time in the park, in an extreme example, a total of 10 persons B were photographed as a result. There may be a case where the total number of photos taken by A is zero. In such a case, it is expected that the person A is greatly dissatisfied with this service. Therefore, it is desirable for the server 1 to have an adjustment function for providing services to all photograph applicants 2 as equally as possible.

  The third embodiment can cope with at least this problem. FIG. 12 shows an imaging sequence according to the third embodiment, and shows a sequence that replaces the X portion sequence in FIG. 6 in the first embodiment. In order to avoid duplication of description, the description of the sequence before the portion X in FIG. 6 is omitted, and the characteristic sequence of the third embodiment will be described below.

  After the position information of the photograph applicant 2 is transmitted to the server 1 and logging of the position information of the photograph applicant 2 is started, the server 1 also starts recording the progress information of the photograph applicant 2 (step S501). This progress information is information indicating the service performance that the photograph applicant 2 enjoyed from this system, and includes, for example, the elapsed time that the photograph applicant 2 has received the service, the cumulative number of photographs taken, and the like. The elapsed time for which the service is received may be, for example, the elapsed time since the “user position, ID transmission operation (step S304)” described in FIG. 6 is performed, or the elapsed time in the morning or afternoon is divided. For example, various devices may be applied according to the contents of services performed using the system.

Subsequently, the server 1 extracts the photograph applicant 2 existing around the photographer 5 (step S502). Further, when the server 1 transmits the extracted location information of the photograph applicant 2 to the photographer device 6, the server 1 also transmits the progress information of the photograph applicant 2 (step S503). As shown in FIG. 11, the photographer device 6 displays their progress information 14A and 14B together with icons 13A and 13B indicating the position of the photograph applicant 2. The photographer 5 can confirm these pieces of information (step S504). Accordingly, when there are a plurality of photograph applicants 2 around him, the photographer 5 can select a subject to be photographed next in consideration of the progress information of each person (step S505). For example, in the example of FIG. 11, the person B has been photographed for a total of six images in one hour, whereas the person A has been photographed for a total of two images after six hours. In this case, the photographer 5 can level the service enjoyment balance between the persons by selecting the person A whose cumulative number of photographs is less than the elapsed time as the subject.

  When the service management side prepares a staff member who will be the photographer 5, each staff member can monitor the progress information of each photograph applicant 2 and make adjustments so that the number of photographed images does not vary. . Even when the photographer 5 is a general person, it is expected that the person who has a small number of shots will be able to purchase his / her own photograph, so that the balance of the number of shots can be adjusted naturally. Alternatively, it is also preferable to provide an incentive to give points or coupons to a person who has taken a person with a small number of shots so that the balance of the number of shots can be positively adjusted.

  The photographer 5 performs a subject selection operation on the photographer device 6 and records the information on the photographer device 6 (step S506). Thereafter, the photographer 5 appropriately adjusts the angle of view and the camera lens magnification so as to include the selected subject using the camera 8 possessed (step S507), and performs a shutter operation. In the camera 8, a photograph showing the photograph applicant 2 selected as a subject is generated and stored (step S508). The photographed photograph data is transferred from the camera 8 to the photographer device 6 via the communication function described above (step S509). Subsequently, when transmitting the photograph data and the photographer ID from the photographer device 6 to the server 1, information such as the selected subject information, the photographing time, and the photographing position selected by the photographer 5 is also transmitted to the server 1 and stored. (Step S510). Since the subject information corresponding to the photo data has already been obtained, the server 1 does not require subject identification processing. Further, since the cumulative number of photographed subjects is increased by one, the server 1 performs a process of updating the subject progress information (step S511). The subsequent sequence is the same as that of the first embodiment. In the case of buying and selling photographs, the server 1 generates sample data and transmits the specified subject to the user device 3 of the subject.

  In this manner, in the third embodiment of the present invention, it is possible to suppress the variation in the amount of service received for each photograph applicant 2, that is, the variation in the total number of photographs with respect to the elapsed time. Satisfaction can be increased.

<Fourth embodiment>
Subsequently, a fourth embodiment of the present invention will be described. When the photograph providing service is performed by a plurality of photographers 5, there is a possibility that the photographing location is biased depending on the photograph applicant 2. Again, as an extreme example, a person may have taken 10 photos through the service, but as a result, all the spots taken could be the same. In this case, it is expected that the person will be dissatisfied with the service for obtaining only pictures of the same scenery. Therefore, it is desirable to provide a function for improving the quality of service so that all photograph applicants 2 can be provided with photographs at various shooting locations.

  The fourth embodiment can cope with at least this problem. FIG. 14 shows a shooting sequence according to the fourth embodiment, and shows a sequence that is an alternative to the sequence of the X part in FIG. In order to avoid duplication of description, the description of the sequence before the portion X in FIG. 6 is omitted, and the characteristic sequence of the fourth embodiment will be described below.

After the position information of the photograph applicant 2 is transmitted to the server 1 and logging of the position information of the photograph applicant 2 is started, the server 1 also starts recording progress information of the photograph applicant 2 (step S601). The progress information of the third embodiment includes the elapsed time that the photograph applicant 2 is receiving service, the cumulative number of photographed photos, and the like. In this embodiment, the location where the photograph applicant 2 was photographed. Further history of When the progress information including these three pieces of information is transmitted to the photographer device 6 of the photographer 5 to cause the photographer 5 to arbitrarily select a subject as in the third embodiment, the amount of information processed by the photographer 5 In many cases, it may take time to make a selection decision. In general, since the photograph applicant 2 desires to obtain as many photographs as possible through this service, it is preferable to set the system so that the photographer 5 can spend as much time as possible on photographing.

  Therefore, in the fourth embodiment, the server 1 is provided with a step (step S603) of identifying a subject with the highest priority for photographing for each photographer 5. For example, when there are a plurality of photograph applicants 2 around the photographer 5, the server 1 has a small cumulative number of photographs for the elapsed time (unit time) from among the plurality of photograph applicants 2, and the location The person who has not yet taken a photo is selected as the highest priority subject. The server 1 transmits the position information of the highest priority subject to the photographer device 6 of the photographer 5 (step S604), and the photographer 5 confirms the position information displayed on the photographer device 6 (step S605).

  Examples displayed on the photographer device 6 are shown in FIGS. 13A and 13B. FIG. 13A and FIG. 13B show an example where two photographers P1 and photographer P2 exist at a short distance. FIG. 13A is an example of information displayed on the photographer device 6A of the photographer P1, and the position 12A of the photographer P1 and the position 13A of the photographer A nearby are displayed on the surrounding map 11A. . FIG. 13B is an example of information displayed on the photographer device 6B of the photographer P2, and the position 12B of the photographer P2 and the position 13B of the photographer B nearby are displayed on the surrounding map 11B. . In this example, the highest priority subject for the photographer P1 is the photograph applicant A, and the highest priority subject for the photographer P2 is the photograph applicant B. That is, the photographer B for the photographer P1 and the photographer A for the photographer P2 are not intentionally displayed on the system side, so that the photographer does not hesitate which photograph applicant is the subject. .

  Various conditions can be considered when the server 1 selects the highest priority subject. For example, in the case where the total number of photographs for the elapsed time (unit time) of the photograph applicants A and B is the same, it is preferable to consider the information on the location where each photograph applicant has already taken. If the photograph applicant A has already been photographed at the position 12B of the photographer P2, the photographer P1 at the other position 12A may be notified with priority. On the other hand, if the photograph applicant B has already been photographed at the position 12A, the photographer P2 at the other position 12B may be preferentially notified. FIG. 13A and FIG. 13B are examples displayed on each photographer device 6 as a result of selecting the highest priority subject from such a viewpoint.

It should be noted that other parameters may be introduced to select the highest priority subject, and any evaluation function may be provided. For example, if the sales record of a photograph taken at a specific place is high from the sales record data of the photograph, the weight may be increased as a place where there is a demand for photography. It should be noted that, although the demand for photographs in the daytime is low, a place where the demand for photographs increases because it becomes a night view spot at night, the weight may be expressed as a function of time. Further, the server 1 may accumulate the photo purchase record information for each photograph applicant 2, and a function for evaluating the purchase record for each photograph applicant 2 may be used as one of the evaluation functions. For example, a photograph applicant who has a high purchase rate or a large number of purchases may increase the priority to be selected as the highest priority subject. As a result, it is possible to provide photographs of various scenes and a large number of photographs to those who are highly likely to purchase photographs, and the use of the service can be expected. Alternatively, when the photograph applicant has a purchase record of a photograph of a scene similar to the current scene (scene where the photograph applicant currently exists), the priority to be selected as the highest priority subject may be increased. For example, if there is a photographer who wants to purchase a lot of photographs at sea, and the system selects the photographer as the top priority subject, the possibility of providing a photograph that suits the photographer's preference. Will increase. In this way, shooting can be devised according to the characteristics of individual photographers. Furthermore, when the above-described shooting request is received from the photograph applicant 2 through the user device 3, the evaluation function may determine the priority for shooting as a subject in consideration of shooting request information.

  Note that the server 1 may provide a photographing instruction (recommendation such as a photographing method) to the photographer based on the photograph purchase record information. For example, when informing a photographer of a photograph applicant who has a low purchase record as a subject, a recommended background or composition may be recommended to the photographer. As a result, the photographer can provide high-quality photographs, and the desire to purchase can be enhanced.

  Thereafter, the photographer 5 appropriately adjusts the angle of view and the camera lens magnification so as to include the selected subject using the camera 8 possessed (step S606), and performs a shutter operation. In the camera 8, a photograph showing the photograph applicant 2 is generated and stored (step S607). The photographed photograph data is transferred from the camera 8 to the photographer device 6 via the communication function described above (step S608), and further transferred from the photographer device 6 to the server 1 (step S609). Since the subject information corresponding to the photographic data has already been obtained, the server 1 does not require subject identification processing, and processing for updating the subject progress information is performed (step S610). The subsequent sequence is the same as that of the first embodiment. In the case of buying and selling photographs, the server 1 generates sample data and transmits it to the identified user device 3 of the subject.

  The point of the present embodiment is that the server 1 selects the highest-priority subject that each photographer 5 should next photograph based on the set evaluation function, so that the photographer can shoot without hesitation in selecting the subject. You can concentrate on it. Moreover, a photograph can be provided according to the situation and characteristics of each photograph applicant 2, and the satisfaction of the photograph applicant 2 can be enhanced.

<Fifth embodiment>
A fifth embodiment of the present invention will be described. This service is premised on having another person (an arbitrary photographer 5) take a picture of the photograph applicant 2. In developing and spreading such services, it is desirable to pay sufficient attention to the privacy protection of the photograph applicant 2. One of the possible issues is the possibility of using privately a photograph taken by the photographer 5. For example, the photographer 5 may post a photograph to the SNS, post it on a website, or use it as an advertising material. In the first place, it is expected that many people feel anxious about the fact that others have their own photos. In order to deal with such a problem, it is preferable to provide a system in the system so that the photographer 5 cannot use the photograph privately.

Therefore, in this embodiment, the privacy protection function described below is implemented in the photographer device 6 or the camera 8. For example, in the case of a device in which the photographer device 6 and the camera 8 are integrated, such as a smartphone, all photographed photograph data may be automatically encrypted by the photographer software 7. The encryption key is not given to the photographer 5 and is held only by the server 1 or the photograph applicant 2 who is the subject. Thereby, browsing of the photograph by the photographer 5 can be prevented. Even if photo data is leaked, there is no worry of third-party browsing or unauthorized use. The photographer software 7 may automatically delete the photograph data from the photographer device 6 after transmitting the photograph data to the server 1. This completely eliminates the possibility of unintended use of data. In order to prevent the privacy protection function by the photographer software 7 from being avoided, the server 1 may not accept a photograph taken without using the photographer software 7.

  It is also preferable to let the photographer 5 use the camera 8 equipped with the automatic encryption memory. By using the automatic encryption memory, all the data photographed by the camera 8 is automatically encrypted. In this case as well, the encryption key is not given to the photographer 5 and is held only by the server 1 or the photograph applicant 2 who is the subject. As a result, it is possible to prevent the photographer 5 or a third party from browsing or using the camera for other purposes. In order to prevent the privacy protection function provided by the automatic encryption memory from being avoided, the photograph taken without using the automatic encryption memory may not be accepted by the server 1.

  Alternatively, a dedicated camera 8 equipped with a privacy protection function may be lent to the photographer 5 of this service. For example, the camera 8 having the above-described automatic encryption function and post-transmission data deletion function may be used. The camera 8 may have a function of transmitting data to the server 1 but does not have an interface for extracting data (for example, a memory cannot be removed or a USB port is not provided).

<Others>
The above-described embodiments are merely preferred specific examples of the present invention, and the scope of the present invention is not limited to those of the above-described embodiments. Those skilled in the art can employ various configurations within the scope of the technical idea of the present invention.

  For example, in the above embodiment, the GPS is used to acquire the position information of the photograph applicant 2 and the photographer 5, but the position information may be acquired by other methods. As position information acquisition means, there are a method of calculating a position from a difference in radio wave intensity from a plurality of Wi-Fi base stations, and a method of estimating a self-position based on signal strength determination of a beacon transmitter installed separately. There is also a method of calculating the position from the amount of movement relative to the reference position by utilizing sensors (acceleration sensor, magnetic sensor, angular velocity sensor, etc.) provided in the user device or the photographer device. By using these, position information can be obtained even indoors or underground facilities where GPS signals cannot be received.

  In the above-described embodiment, three examples of the progress information of a certain person are the elapsed time that the person has received the service, the number of times the person has been photographed, and the history of the place where the person has been photographed. The progress information preferably includes at least one of these three pieces of information, but may be information other than these three pieces of information. That is, any information may be used as the progress information as long as the service performance (degree) enjoyed by the person can be evaluated. For example, the photograph purchase record information for each photograph applicant described in the explanation of the evaluation function may be used. In this case, each photographer can read the preference from the purchase record information for each photograph applicant, and can devise photography uniquely so as to meet the preference. Thus, satisfaction can be raised by providing a service corresponding to each characteristic of a photograph applicant.

  In the above embodiment, a method is adopted in which the server 1 generates photo sample data and transmits it to the user device 3, and the photo applicant 2 transmits the original photo data after completing the purchase procedure. Instead of this method, the original photo data is sent to the user device 3 from the beginning, and the user software 4 restricts access to the original photo data until the photo applicant 2 completes the purchase procedure. May be taken. For example, the original photo data is encrypted until the purchase procedure is completed, and only the sample data subjected to low resolution processing or watermark processing can be browsed. After the purchase procedure is completed, the original photo data is stored. You may decode. According to such a method, since the transmission of the photo data from the server 1 to the user device 3 is only required once, it is excellent in convenience.

  The present invention supplies a program that realizes one or more functions of the above-described embodiments to a system or apparatus via a network or a storage medium, and one or more processors in the computer of the system or apparatus read and execute the program This process can be realized. It can also be realized by a circuit (for example, ASIC) that realizes one or more functions.
