  Hereinafter, the present invention will be described through embodiments of the invention, but the following embodiments do not limit the invention according to the claims. In addition, not all the combinations of features described in the embodiments are essential for the solving means of the invention.

  FIG. 1 is a conceptual diagram illustrating the concept of a shooting request using the request terminal 100 according to the present embodiment. For example, a client who wants to take a picture of himself as a subject uses the request terminal 100 to request a person who has a camera that is in the vicinity. Until now, the act of asking other people to shoot depends on the good intentions of the other person, and the requesting side is hesitant to ask, and the requested side is difficult to refuse once requested. However, the requesting terminal 100 relaxes such a barrier. The system will be described in order below.

  The request terminal 100 can communicate with a camera held by a candidate who requests imaging. The imaging requester transmits an imaging request signal from the request terminal 100 to the candidate's camera together with certain information as will be described later. The candidate who is present in the surroundings confirms the shooting request signal received by his camera, and then transmits an acceptance signal from his camera to the request terminal 100 to accept the request from the shooting client. The intention of acceptance can be communicated to the client. Thereafter, if the candidate camera receives a formal photographing request signal from the request terminal 100, the photographing request is established.

  The request terminal 100 divides the current location, for example, with a radius of 10 m, 30 m, or 80 m, and limits the transmission range so that the shooting request signal arrives in order from the short distance side in order to try shooting requests in order from candidates who are in close proximity. can do. Therefore, the request terminal 100 can request a candidate who is at a distance to take a picture by automatically extending the transmission range even if the candidate is not found at a short distance. In addition, when requesting a specific candidate among candidates in view, such as possessing a specific camera, the imaging requester transmits an imaging request signal aiming at the distance that the candidate is located. You can also.

  The request terminal 100 may be a dedicated terminal that requests photographing, or may be incorporated as an application of another mobile terminal. For example, it can be incorporated into a mobile phone, a music terminal, a game machine or the like that is frequently carried to function as the request terminal 100. If such a request terminal 100 is carried, the user can obtain a desired photographed image without carrying the camera. Of course, the function of the request terminal 100 can be incorporated into the camera. If the camera has the function of the request terminal 100, it is possible to request photographing without handing over its own camera to the photographing acceptor, thereby avoiding the risk of handing over the camera to another person. Furthermore, it is possible to request shooting depending on specifications that the camera does not have.

  As described above, the previous shooting request has depended on the good intentions of the other person. However, in the shooting request using the request terminal 100, the shooting request is given to the shooting acceptor who responds to the shooting request. Reduce client's habit. In return, various forms are possible. For example, after having the shooting acceptor take a picture, the change is made so that the shooting requester takes a picture of the shooting acceptor as a subject, or presents the confectionery they have, or more directly Money can be exchanged. When the imaging requester inputs any viewing condition into the requesting terminal 100 in advance, the requesting terminal 100 includes the viewing condition input in the imaging request signal and transmits it to the candidate's camera. In this embodiment described below, points managed in electronic commerce are used as a reward. As the number of points increases, the monetary value increases. For example, the points can be converted into more expensive products.

  FIG. 2 is an overall configuration diagram for explaining the transaction of points related to rewards. The points are managed by a management company 310 operated by a manufacturer of the request terminal 100, a camera manufacturer, or the like. The management company 310 issues points through the server 311 and exchanges and settles points and money.

  The server 311 is connected to the network 300, and points circulate through the network 300. The user of the request terminal 100 acquires the points precharged when the request terminal 100 is purchased. When the points are reduced by repeating the imaging request, the requesting terminal user charges the points from the server 311 by connecting the requesting terminal 100 directly to the network 300 or via an own personal computer or the like. To do. The charge of points is managed by a billing format, and is settled by, for example, a credit card.

  The requesting terminal user sets the number of points in the requesting terminal 100 as a reward condition, and requests the camera user to take a picture. When photographing is performed according to the request, the requesting terminal user transfers points from the requesting terminal 100 to the camera user's camera in exchange for the photographed image. The points that the request terminal user has with respect to the request terminal 100 may be managed by the request terminal 100 or may be managed by the server 311 together with the ID of the request terminal 100 and the like. Similarly, the points that the camera user has with respect to the camera 200 may be managed by the camera 200, or may be managed by the server 311 together with the ID of the camera 200. Therefore, when the server 311 manages the receipt and payment of points, the transfer of points is not performed directly between the request terminal 100 and the camera 200, but by specifying the IP address of the user who manages the points in the server 311. Can be executed. For example, a camera user who receives a point transmits its own IP address from the camera 200 to the requesting terminal 100, and obtains a point by having the requesting terminal 100 transmit a point corresponding to the reward to the IP address.

  The camera user who has accumulated points can receive a desired product from, for example, the camera store 320 in exchange for the points. The clearing of points may be performed via a clearing terminal installed at the store of the camera sales store 320 or may be performed by ordering products via the network 300. The camera store charges the management company 310 for the price of the product delivered to the camera user and performs settlement. The management company 310 can grasp the purchase trend of the camera user as a consumer via the camera store 320.

  The server 311 not only manages points, but can also serve as a storage for storing captured image data related to a shooting request. For example, when the request terminal 100 cannot receive the captured image data, such as when the request terminal 100 does not have sufficient memory capacity or when the communication environment is poor for communicating the captured image data, Is sent to the IP address of the server 311 designated by the requesting terminal user. The captured image data temporarily stored in this manner is later downloaded by the requesting terminal user and is used. The captured image data can be downloaded not only by the request terminal 100 but also by, for example, a personal computer owned by the request terminal user.

  Next, a specific configuration of the request terminal 100 will be described. FIG. 3 is an external view of the request terminal 100. Since the requesting terminal 100 has a function of letting photographing to an external camera and capturing and reproducing the photographed image data from the camera, the request terminal 100 is generally similar to a configuration in which the photographing function is removed from the camera.

  The request terminal 100 includes a display unit 101 and a plurality of operation members 102 as components on the appearance. The display unit 101 displays various menu items, setting buttons, and the like regarding various settings of the request terminal 100, in addition to images and information transmitted to and received from the camera 200 such as a photographing acceptor. Specifically, the operation member 102 includes an OK switch 103 that executes a selected function, a cross switch 104 that is used to move a displayed setting item, and a seesaw switch that is used to instruct an enlargement / reduction of a display image. 105, a button switch group 106 for displaying various setting items and the like. The cross switch 104 also has a rotation function and is used for frame display instruction for image display. Further, a touch panel sensor 107 is provided on the display unit 101 so as to detect a finger contact of the requesting terminal user and realize a function corresponding to the contact position.

  The request terminal 100 is driven by the battery 108. The battery 108 can be attached to and detached from the request terminal 100, and is constituted by a secondary battery such as nickel metal hydride. The recording medium 109 can also be attached to and detached from the request terminal 100. The recording medium 109 is configured by a non-volatile memory such as a flash memory, for example, and records received captured images and the like.

  Although a specific processing flow and a characteristic display screen configuration will be described later, in the example of the figure, a state in which a captured image received from the camera 200 of the imaging acceptor is displayed on the display unit 101 is shown. . In the case of the figure, the point 150P has already been transmitted and presented to the request acceptor as a return condition for the photographing request, and the photographing requester determines whether to send the point 150P to the request acceptor as it is or to change the presentation point. This represents a scene to be selected while viewing the received photographed image.

  FIG. 4 is a system configuration diagram of the request terminal 100. The entire request terminal 100 is directly or indirectly controlled by the system control unit 120. The system control unit 120 is connected to the system memory 121 and the internal memory 122. The system memory 121 is an electrically erasable / recordable non-volatile memory, and is composed of, for example, an EEPROM (registered trademark). The system memory 121 records constants, variables, programs, and the like necessary when the request terminal 100 operates so that they are not lost even when the request terminal 100 is not operating. In particular, in this embodiment, the point balance is also recorded. The system control unit 120 develops constants, variables, programs, and the like as appropriate in the internal memory 122 and uses them for controlling the request terminal 100.

  The internal memory 122 is a random access memory that can be read and written at high speed, and for example, a DRAM, an SRAM, or the like is used. The internal memory 122 also serves as a work memory in image processing and compression processing performed by the image processing unit 125. Furthermore, it also has a role of temporarily storing image data processed for a predetermined purpose. Therefore, the internal memory 122 has a sufficient memory capacity corresponding to these roles.

  The network connection module 123 is a communication unit used when the request terminal 100 is connected to the network 300 as described above. For example, a wireless LAN that can transmit and receive data using wireless communication is applied. The short-range communication module 124 is a communication unit that wirelessly communicates with the camera 200 of the candidate who requests imaging and the imaging acceptor as described with reference to FIG. For example, Bluetooth, which is a short-range communication module assuming a reach distance of about 100 m, is applied. In particular, in this embodiment, a plurality of classes of modules having different reach distances depending on the radio wave output are mounted, and the transmission range can be selected so that the imaging request signal reaches the candidates in order from the short distance side. ing.

  When the request terminal 100 is set to directly receive the image data related to the photographing request from the camera 200 of the photographing acceptor, the requesting terminal 100 receives the short distance communication module 124. When set to receive via the network 300, the request terminal 100 receives via the network connection module 123. The same applies to a case where a pre-image to be described later is received. The captured image data received in this way is subjected to image processing such as decompression, color conversion processing, gamma processing, and white balance processing by the image processing unit 125, and a D / A converter 127 according to the control of the display control unit 126. Is converted to an analog signal and displayed on the display unit 101.

  The received captured image data is recorded on the recording medium 109 via the recording medium IF128. When the recording medium 109 is not loaded or there is not enough free space in the recording medium 109, the received captured image data may be transferred to the designated IP address via the network connection module 123. it can. In addition, the system control unit 120 can read out the captured image data recorded on the recording medium 109 and display it on the display unit 101.

  The power control unit 129 communicates with the battery 108 to detect remaining power and monitor power supply. Further, when the battery 108 is charged, power supply from the connected AC power source is controlled. The GPS module 130 receives a signal from a GPS satellite and acquires latitude, longitude, and altitude information where the request terminal 100 exists. The system control unit 120 can appropriately detect information regarding the position where the request terminal 100 exists from the GPS module 130.

  The image analysis unit 131 performs image analysis on the received captured image data. Specifically, it detects the amount of high-frequency components in the image, analyzes the blurring state and in-focus state of the image, calculates a histogram from the image data, confirms the presence or absence of blackout, whiteout, etc. Face detection is performed, and face recognition is performed to determine whether a registered person's face is included.

  Next, a specific configuration of the camera 200 that can receive a shooting request from the request terminal 100 will be described. FIG. 5 is an external view of the camera 200 viewed from the back side. Here, a compact digital camera in which a lens optical system is integrally formed will be described as an example, but a lens interchangeable camera may be used.

  In addition to the display unit 201, a plurality of operation members 202 are provided on the back surface of the camera 200. Specifically, a mode switch 203 used for switching modes such as a shooting mode, a metering mode, and an AF mode, a playback switch 204 for reproducing captured image data, a menu switch 205 for displaying various setting items, and a captured image. An erase switch 206 for erasing is provided. Further, a cross switch 207 used for moving the displayed setting items and the like, and an OK switch 208 for executing the selected function are provided. The cross switch 207 also has a rotation function, and is used for an image display frame advance instruction and the like. In addition, a zoom switch 209 for instructing an angle of view adjustment is provided. The zoom switch 209 is a seesaw switch, and is used for enlarging and reducing instructions when reproducing image data. Further, a touch panel sensor 210 is provided on the display unit 201 so as to detect a photographer's finger contact and realize a function corresponding to the contact position. In addition, the camera 200 includes a release switch 211. The release switch 211 includes a push button that can be detected in two steps in the push-down direction, and accepts a shooting preparation instruction and a shooting instruction.

  The camera 200 is driven by a battery 212. The battery 212 can be attached to and detached from the camera 200, and is constituted by a secondary battery such as nickel metal hydride. The recording medium 213 can also be attached to and detached from the camera 200. The recording medium 213 is configured by a non-volatile memory such as a flash memory, for example, and records captured images. In the example shown in the figure, a photographed image taken in accordance with the photographing request is shown on the display unit 101, and whether or not this photographed image is to be transmitted to the requesting terminal 100 of the photograph requester is determined. Represents a scene to be selected while viewing the captured image.

  FIG. 6 is a system configuration diagram of the camera 200. The camera 200 includes an optical system 220. The optical system 220 mainly includes a zoom lens 221, a focus lens 222, a correction lens unit 223, a lens shutter 224, and the like. The subject image enters the optical system 220 along the optical axis 219 and forms an image on the imaging surface of the image sensor 231.

  The image sensor 231 is an element that photoelectrically converts an optical image that is a subject image that is incident through the optical system 220, and for example, a CCD or a CMOS sensor is used. The subject image photoelectrically converted by the image sensor 231 is converted from an analog signal to a digital signal by the A / D converter 232. The charge readout control of the image sensor 231 and the conversion control of the A / D converter 232 are synchronized by a clock signal supplied from the timing generator 234 that has received synchronization control from the memory controller 233.

  The subject image converted into the digital signal is sequentially processed as image data. The image data converted into a digital signal by the A / D converter is temporarily stored in the internal memory 235 under the control of the memory control unit 233. The internal memory 235 is a random access memory that can be read and written at high speed, and for example, a DRAM, an SRAM, or the like is used. The internal memory 235 serves as a buffer memory that waits for the order of image processing when image data is continuously generated at high speed in continuous shooting and moving image shooting. In addition, the image processing unit 237 also serves as a work memory in the image processing and compression processing. Furthermore, it also has a role of temporarily storing image data processed for a predetermined purpose. Therefore, the internal memory 235 has a sufficient memory capacity corresponding to these roles.

  The system memory 236 is an electrically erasable / recordable nonvolatile memory, and is configured by, for example, an EEPROM (registered trademark). The system memory 236 records constants, variables, programs, and the like necessary when the camera 200 is operating so that they are not lost even when the camera 200 is not operating. A system control unit 250 that directly or indirectly controls the entire camera 200 develops constants, variables, programs, and the like in the internal memory 235 as appropriate, and uses them to control the camera 200. In particular, in the present embodiment, the system memory 236 also records the point balance relating to the camera 200.

  The image processing unit 237 converts the image data into a predetermined image format in accordance with the set shooting mode and instructions from the user. For example, when a JPEG file is generated as a still image, image processing such as color conversion processing, gamma processing, and white balance processing is performed, and then adaptive discrete cosine conversion is performed to perform compression processing. Also, when an MPEG file is generated as a moving image, intra-frame coding and inter-frame coding are applied to a frame image as a continuous still image generated by reducing the number of pixels to a compression process. Do.

  Still image data and moving image data processed by the image processing unit 237 are recorded on the recording medium 213 from the internal memory 235 via the recording medium IF 240. Note that the system control unit 250 prohibits recording on the recording medium 213 regarding the captured image data requested by the request terminal 100 and captured by the requester. The captured image data that is prohibited from being recorded on the recording medium 213 waits in the internal memory 235 until it is transmitted to the imaging request terminal 100. Then, it is erased from the internal memory 235 after the transmission is completed.

  The image data processed by the image processing unit 237 generates display image data in parallel with the image data processed for recording. The generated image data for display is converted into an analog signal by the D / A converter 239 under the control of the display control unit 238 and displayed on the display unit 201. Regardless of whether recording is performed or not, if image data for sequential display is generated and displayed on the display unit 201, a live view function can be realized. Further, the system control unit 250 can also display various menu items related to various settings of the camera 200 on the display unit 201 with or without displaying an image.

  The network connection module 241 is a communication unit used when the camera 200 is connected to the network 300 and is used for the use described with reference to FIG. For example, a wireless LAN that can transmit and receive data using wireless communication is applied.

  The short-range communication module 242 is a communication unit that performs wireless communication with the request terminal 100. Therefore, a communication module capable of communicating with the short-range communication module 124 mounted on the request terminal 100 is applied to the short-range communication module 242. For example, Bluetooth can be used as described above.

  When using Bluetooth, pairing for establishing mutual communication first sets the near field communication module 242 of the camera 200 to a searchable state. The searchable state is a reception state in which the camera 200 can receive a request from the request terminal 100. When the camera user intends to accept the shooting request, the camera user places the short-range communication module 242 in a searchable state. Next, the request terminal 100 performs a search operation from the short-range communication module 124 of the request terminal 100 before transmitting the imaging request signal. Then, a list of surrounding cameras 200 in a searchable state is acquired. The short-range communication module 124 of the requesting terminal 100 sequentially designates these partners and inputs a pass key to each other to realize pairing. In this way, the request terminal 100 can acquire information about the camera 200 that is present in the vicinity, and can transmit a photographing request signal to the camera 200.

  When the request terminal 100 is set to directly receive image data related to a shooting request from the camera of the shooting acceptor, the camera 200 transmits the image data via the short-range communication module 242. When set to receive via the network 300, the camera 200 transmits via the network connection module 241. The same applies to the case where a pre-image to be described later is transmitted.

  The zoom lens 221, the focus lens 222, the correction lens unit 223, and the lens shutter 224 constituting the optical system 220 are respectively controlled by the zoom control unit 243, the focus control unit 244, and the image stabilization drive control under the overall control of the system control unit 250. Controlled by the unit 245 and the exposure control unit 246. The zoom control unit 243 drives the zoom lens 221 in accordance with a user instruction to change the angle of view of the subject image. The focus control unit 244 controls the focus lens 222 so that the subject image in a specific area is focused on the light receiving surface of the image sensor 231 based on the contrast AF information using continuously acquired image data. To drive.

  The image stabilization drive control unit 245 includes a position detection sensor that detects the position of the correction lens of the correction lens unit 223 and a shake detection sensor that detects a shake applied to the camera 200. The image stabilization drive control unit 245 drives the correction lens in consideration of the output of the position detection sensor so as to cancel out the shake of the camera 200 detected from the shake detection sensor. As a result, the subject image maintains a stable imaging state on the light receiving surface of the image sensor 231. The exposure control unit 246 drives the lens shutter 224 based on the exposure value obtained by the system control unit 250 analyzing the image data processed by the image processing unit 237, and adjusts the aperture and shutter speed of the incident subject image. To do.

  The camera 200 includes a plurality of operation members 202 that receive operations from the user. However, the system control unit 250 detects that these operation members 202 have been operated, and executes an operation corresponding to the operation. The camera 200 includes a release switch 211. The release switch 211 executes AF, AE, etc., which are shooting preparation operations by detecting SW1 that is the first-stage depression, and acquires the subject image by the image sensor 231 by detecting SW2 that is the second-stage depression. Perform the action.

  The power control unit 247 communicates with the battery 212 to detect remaining power and monitor power supply. Further, when the battery 212 is charged, power supply from the connected AC power source is controlled. The GPS module 248 receives a signal from a GPS satellite, and acquires latitude, longitude, and altitude information where the camera 200 exists. The system control unit 250 can appropriately detect information regarding the position where the camera 200 exists from the GPS module 248.

  Next, a flow of a series of shooting requests using the request terminal 100 and the camera 200 will be described. First, a series of flows from the request terminal 100 side will be described. FIG. 7 is a diagram illustrating a shooting request flow by the request terminal 100.

  When the request terminal 100 is turned on and activated, the system control unit 120 determines in step S101 whether the balance P of points managed in the system memory 121 is below a predetermined threshold Pa. Judge whether or not. The threshold Pa is a point balance that is determined to be insufficient, and a point balance that is considered difficult to continue the imaging request is set. If it is determined that the balance P is less than Pa, the process proceeds to step S102, where the system control unit 120 displays on the display unit 101 that the point balance is insufficient and prohibits photographing requests, and ends a series of operations.

  If the balance P exceeds Pa and it is determined that a photographing request can be made, the process proceeds to step S103, and the system control unit 120 acquires the current position of the request terminal 100 from the GPS module 130. Subsequently, the process proceeds to step S <b> 104, and the system control unit 120 receives imaging conditions desired by the imaging client via an input to the operation member 102. Further, in step S105, an input of a return condition for this photographing request is similarly accepted. FIG. 12 shows an example of a user interface screen relating to the processing of step S104 and step S105. FIG. 12 is an input screen for desired shooting conditions and viewing conditions as shooting request information.

  The imaging request information is information transmitted from the request terminal 100 to the camera 200 via the short-range communication module 124 as an imaging request signal, and is a material for determining whether or not the user of the camera 200 receives an imaging request. The imaging request information first includes a requester name 401, a requester image 402, a request ID 403, and an image transmission destination IP address 404 as unique information of the imaging requester. The client name 401 may be a common name or anonymity, and the client image 402 may be an illustration or may be omitted. These pieces of information are input in advance from the operation member 102, the recording medium 109, and the like, and are stored in the system memory 121. The request ID 403 is a unique ID number generated for each shooting request, and is used as an identification number for distinguishing from other shooting requests in a series of shooting request processing operations. Accordingly, this request ID 403 is attached to all transmissions and receptions, and individual information is managed and identified by linking to the request ID 403. An image transmission destination IP address 404 represents a transmission destination to which photographed image data related to the request is sent. Based on this information, the system control unit 250 of the camera 200 can transmit the captured image data from the network connection module 241 to the designated IP address of the server 311 via the network 300. The photographing client can also set the transmission destination of the image data to the request terminal 100 itself. In this case, the system control unit 250 of the camera 200 transmits captured image data to the request terminal 100 through communication between the short-range communication module 242 and the short-range communication module 124.

  Desired camera 405 and desired person 406 represent the shooting conditions desired by the client. The desired camera 405 can be selected from options such as “single-lens reflex camera”, “compact camera”, “video camera”, and “anything including a mobile phone with camera” as the camera type. Similarly, the focal length of the lens can be selected. The person who wants to photograph 406 represents a person the photographer wants to photograph, and the photographer can repeatedly operate the cross switch 104 and the OK switch 103 using image data recorded on the recording medium 109, for example. Can be registered sequentially. These pieces of face image information are not only used as a judgment material for the user of the camera 200, but also can be applied to face recognition at the time of photographing, for example, by inputting such face information to the camera 200 side. If, for example, AF or AE control is performed based on the face information received in advance, it is possible to meet the request of the client.

  A reward point 407 represents a reward point as a reward condition set by the photographing client for this photographing request. The payback condition has a meaning of gratitude for performing shooting based on the request, and the shooting requester determines the number of points in consideration of the severity of the desired shooting conditions. The figure shows a state in which the point selection is active, and the photograph requester can instruct the point change by operating the cross switch 104 or the touch panel sensor 107. Note that the number of points may be automatically changed according to the set desired conditions.

  When these inputs are completed and the imaging request signal can be transmitted, the system control unit 120 shifts to a state in which the request button 408 can be selected. In addition, the system control unit 120 is in a state where the cancel button 409 for canceling the imaging request can be selected at any time.

  Returning to FIG. 7, the description of the flow will be continued. If the input by step S104 and step S105 is completed, it will progress to step S106 and the system control part 120 will wait for selection of the request button 408, and will transmit a photography request signal. The photographing request signal includes the specific information of the photographing client, the desired photographing condition, and the return condition as described above, and also includes the current location information of the requesting terminal 100 acquired in step S103. The camera 200 can notify the camera user of how far away the photograph requester is by acquiring the current location information of the request terminal. Such a shooting request signal is transmitted to the camera 200 that has been paired with the requesting terminal 100.

  The system control unit 120 proceeds to step S107 and waits for a predetermined time to receive an acceptance signal transmitted from the camera 200. When the acceptance signal cannot be received, the process proceeds to step S108, and the system control unit 120 determines whether or not the transmission distance of the short-range communication module 124 has reached the maximum. When it is determined that the image has been reached, the process proceeds to step S110. In step S110, the display unit 101 is displayed that the imaging request is not satisfied, and the series of operations is terminated to abandon the imaging requester. If it is determined in step S108 that the transmission distance has not yet reached the maximum, the process proceeds to step S109, and the system control unit 120 extends the transmission range of the short-range communication module 124 and returns to step S106 again.

  If an acceptance signal is received from the camera 200 in step S107, the process proceeds to step S111. In step S <b> 111, the system control unit 120 displays information included in the acceptance signal on the display unit 101. If it is determined in step S112 that a plurality of acceptance signals have been received, the process proceeds to step S113, where the system control unit 120 selects from one of the plurality of imaging request destination candidates displayed on the display unit 101. Accept selection instructions. An example of a user interface screen related to the process of step S113 is shown in FIG. FIG. 13 is a list screen of candidates for photographing request that has transmitted an acceptance signal indicating an intention to accept the photographing request from the own camera 200 to the requesting terminal 100.

  The list is displayed for each candidate who indicates an intention to accept a shooting request. Specifically, for each candidate, the unique information of the candidate and the location of the candidate are displayed. The candidate image 501 and the candidate name 502 as the unique information of the candidate are based on the client image 402 and the client name 401 described above. The camera information 503 is equipment information of the camera 200. Based on the GPS information on the request terminal 100 side and the GPS information on the camera 200 side, the system control unit 120 calculates both directions and distances, and converts them into directions and distances when the camera 200 is viewed from the request terminal 100 side. The candidate position 504 is displayed on the list.

  A radio button 505 is provided at the end of each candidate list, and the photographing requester can select one of the candidates on the list to request photographing. In the case of the figure, a state where the candidate at the lower end is selected is shown. When the candidate selection input is completed and a formal request signal that is a formal photographing request can be transmitted, the system control unit 120 shifts to a state in which the OK button 506 can be selected. In addition, the system control unit 120 is in a state where the cancel button 507 for canceling the imaging request can be selected at any time.

  Returning to FIG. 7 again, the description of the flow will be continued. When the selection of candidates for requesting shooting is completed in step S113, the system control unit 120 transmits a cancel signal for canceling the shooting request to the camera 200 of another candidate who has determined not to request shooting in step S114. . Other candidate cameras 200 display a message on the display unit 201 that the request for photographing has been canceled.

  In the above description, the imaging client has selected one person from a plurality of imaging request destination candidates. However, the system control unit 120 may automatically select one person. Specifically, a candidate that matches the desired camera 405 and the camera information 503 may be selected, or a candidate that is present closest may be selected. In addition, conditions such as a candidate with a candidate image 501, a candidate whose candidate name 502 is not anonymous, and a female candidate are preset in advance, and the candidate that satisfies the most conditions is automatically selected. You may comprise so that it may select.

  When it is a single candidate in step S112 and when a specific candidate is selected in step S113, the system control unit 120 proceeds to step S115, and the system control unit 120 of the specific candidate who actually requests the shooting. A formal request signal is transmitted to the camera 200 to perform formal request processing. Since the formal request process in step S115 is executed by a cooperative operation with the camera 200, the specific process will be described later.

  When the formal request process is completed and the process proceeds to step S116, the system control unit 120 starts a timer built in the system control unit 120 and waits until the captured image data is transmitted in step S117. The photographed image data is transmitted together with a response signal including a request ID 403 indicating that it is data relating to a photographing request. Note that when the captured image data is sent to the server 311, the system control unit 120 receives a response signal from the server. At this time, the response signal may be received together with the reduced captured image data obtained by reducing and resizing the captured image data recorded in the server. The response signal plays a role of indicating that the photographed image data is transmitted in response to the photographing request signal.

  When the system control unit 120 receives the captured image data related to the imaging request, the system control unit 120 proceeds to step S118 and executes a return change process according to the quality of the captured image data. Specific reward changing processing will be described later. Then, the determined reward is subtracted from the point balance managed in the system memory 121, and is sent as a reward signal to the camera 200 of the photographing acceptor or the IP address of the designated server 311. .

  In step S120, the system control unit 120 determines whether or not a point corresponding to the return signal is subtracted from a predetermined threshold value Pb as a result of subtracting the points corresponding to the return signal from the point balance managed in the system memory 121 in step S119. to decide. The threshold value Pb is a point balance that is determined to be insufficient as a balance, and is a point balance that is considered difficult to request continuous shooting. Accordingly, Pb is set to a value slightly larger than Pa. If it is determined that the balance P is less than Pb, the process proceeds to step S121, where the system control unit 120 displays a warning about insufficient point balance on the display unit 101 and then ends a series of photographing request processing. If not, the shooting request process is terminated as it is from step S120.

  Next, a series of flows from the camera 200 side will be described. FIG. 8 is a diagram showing a photographing acceptance flow by the camera 200.

  Prior to receiving the imaging request signal, the system control unit 250 of the camera 200 accepts the imaging request acceptance condition setting in step S201 in advance. For example, it is possible to set a condition such as accepting only when the number of points as a reward condition is more than one point, or accepting only when the distance to the photographing client is several meters or less from the current location.

  If the acceptance condition is set, the process proceeds to step S202, and the system control unit 250 waits until the imaging request signal is received. When the photographing request signal is received, the process proceeds to step S203, where the system control unit 250 analyzes the photographing client specific information, the desired photographing condition, the return condition, and the current location information of the requesting terminal 100 included in the photographing request signal. It is determined whether or not the acceptance condition set in step 1 is met. If it is determined that they do not match, the process returns to step S202 and waits for the reception of the imaging request signal.

  If they match, the process proceeds to step S204, and the system control unit 250 displays the above-described information included in the imaging request signal on the display unit 201. Specifically, a screen similar to the user interface screen shown in FIG. At this time, the system control unit 250 acquires the current position of the camera 200 from the GPS module 248, compares the current position information of the request terminal 100 included in the imaging request signal, and calculates the direction and distance of the request terminal 100 simultaneously. indicate. The user of the camera 200 determines whether to accept the shooting request in consideration of this display information.

  In step S205, when the user determines not to accept the photographing request, the process returns to step S202. If it is determined to accept, the process proceeds to step S <b> 206, and the system control unit 250 transmits an acceptance signal to the request terminal 100 via the short-range communication module 242. Thereafter, in step S207, the system control unit 250 waits for an official request signal to be transmitted from the request terminal 100. When the cancel signal for canceling the photographing request is received instead of the formal request signal, the process proceeds to step S208, and the system control unit 250 displays a message to the effect that the photographing request has been canceled on the display unit 201.

  If the formal request signal is received, the process proceeds to step S209. In step S209, the system control unit 120 executes a shooting operation process according to the shooting request. Since the shooting operation process in step S209 is executed by a cooperative operation with the request terminal 100, the specific process will be described later. In addition, after the camera 200 receives the formal request signal, the user of the camera 200 is set as a photographing acceptor.

  Here, FIG. 14 shows a user interface screen when the formal request signal is received. The imaging request information 601 is information displayed based on the specific information of the imaging client included in the imaging request signal, the desired imaging conditions, the return conditions, and the current location information of the request terminal 100. The formal request signal includes a display instruction signal that causes the display client 201 to display a message generated by the photographing client at the request terminal 100 as described later, and the system control unit 250 displays the display instruction signal. The message of the photograph requester is displayed on the display unit 201 according to the above. The message information 602 is a message of the photograph requester displayed in this way. The displayed message is a type that prompts the photographing acceptor to operate the camera 200 regarding the photographing request.

  Returning to FIG. 8, the description of the flow will be continued. When the shooting related to the shooting request is completed, the system control unit 250 transmits the generated image data to the designated IP address or the requesting terminal 100 in step S210. At this time, for example, the user interface screen shown in FIG. Thereafter, the system control unit 250 receives the return signal in step S211 and ends the series of imaging acceptance flows.

  Next, the formal request process of the request terminal 100 and the photographing operation process of the camera 200 described in step S115 of FIG. 7 and step S209 of FIG. 8 will be described in more detail. FIG. 9 is a diagram illustrating a flow of formal request processing by the request terminal 100 and shooting operation processing by the camera 200. These processes are independently controlled by the requesting terminal 100 and the camera 200, but the processes proceed by interacting with each other while communicating with each other. Therefore, a series of step numbers will be assigned and described sequentially.

  Prior to the transmission of the formal request signal, the system control unit 120 of the requesting terminal 100 accepts a message from the photographing requester to the photographing acceptor in step S301. The message prompts the photographer to operate the camera 200, and the photograph requester may input text using the operation member 102, or the photograph requester selects one of a plurality of prepared messages. You may comprise so that it can. When the client requesting the shooting, it is rare that the shooting acceptor and the camera 200 are in a convenient state for the shooting according to the request. For example, there may be a case where the photographer is crowded or in a direction different from the direction in which the photographer wants to photograph. In such a case, a message such as “Please point the camera at the camera because you are waving your hand” or “Please move to the west with the camera” message from the client Sending is effective. In addition, if it is known from the display of the candidate position 504 that the photographer is far away, the message is “Please switch the zoom lens to the telephoto side” or “Please replace the telephoto lens”. Is also effective.

  The message generated in step S302 is converted into a display instruction signal to be displayed on the display unit 201 of the camera 200, and is transmitted to the camera 200 together with the formal request signal in step S302. When the camera 200 receives the formal request signal from the request terminal 100, the camera 200 starts the photographing operation process.

  A message from the photograph requester is displayed on the display unit 201 of the camera 200, and the photographing acceptor operates the camera 200 in accordance with the message to execute pre-photographing that is temporary photographing before the main photographing. In step S303, the system control unit 250 executes pre-photographing processing to generate a pre-image. The pre-image is a small-sized image that has been thinned out from the main image, and is used for a prior check by the client.

  The photographing acceptor can create a comment for the photographing client prior to the main photographing while confirming the generated pre-image on the display unit 201. In step S304, the system control unit 250 receives a comment from the photographing acceptor. Regarding the generation of the comment, the photographing acceptor may input text using the operation member 202, or the photographing acceptor may select one from a plurality of comments prepared in advance. The comment relates to a proposal for shooting. For example, when the generated pre-image is finished under the influence of backlight, a comment such as “Let's shoot with a slight change in angle” is effective. In addition, when the sunset is used as a background, a comment such as “Adjust so that a little reddish appears” is also effective.

  In step S305, the system control unit 250 transmits the pre-image and the comment generated in this way to the request terminal 100 via the short-range communication module 242. In step S <b> 306, the system control unit 120 of the request terminal 100 receives these pre-images and comments from the camera 200 via the short-range communication module 124 and displays them on the display unit 101.

  The photograph requester processes the pre-image at the request terminal 100 and inputs an instruction relating to the photographing condition in order to notify the photograph acceptor of his / her wish while taking into consideration the comment of the photograph acceptor. In step S307, the system control unit 120 accepts the processing of the photographing client for the pre-image, and in step S308 accepts an instruction regarding the photographing conditions.

  FIG. 15 shows an example of a user interface screen related to the processing in steps S307 and S308. FIG. 15 is an input screen for giving an instruction to change the shooting conditions for the pre-shooting that generated the pre-image. The received pre-image 701 is displayed in full width on the display unit 101, and the photographing client displays a rectangle representing a desired angle of view by operating the seesaw switch 105. For example, when a narrower angle of view is desired, a frame smaller than the entire frame of the pre-image 701 is displayed. Then, the cross switch 104 is operated to move the frame vertically and horizontally. The desired angle of view 702 is generated in this way, and the angle of view of the pre-image 701 and the unnecessary area 703 surrounded by the desired angle of view 702 are displayed in a net shape. When a wide angle of view is desired, the outer frame as the desired angle of view 702 is displayed in the full width with respect to the display unit 101, the pre-image 701 is reduced and moved, and the relative relationship between the pre-image 701 and the desired angle of view 702 is displayed. Express relationships.

  The slide bar 704 is a bar for adjusting the brightness of the pre-image, and the pre-image becomes dark when it is slid to the left, and brighter when it is slid to the right. Similarly, the slide bar 705 is a bar for adjusting the white balance of the pre-image. The slide bar 705 is reddish when slid to the left, and is bluish when slid to the right. The processing for these pre-images is executed by the image processing unit 125.

  The system control unit 120 accepts input as setting items for items that cannot be expressed directly by processing the pre-image and items that are difficult to process the pre-image. For example, when it is desired to focus only on the main subject and increase the amount of background blur, the former selection is accepted from “increase blur amount” and “sharply” prepared as the blur amount item 706.

  When these inputs are completed and the change instruction signal can be transmitted, the system control unit 120 shifts to a state in which the OK button 707 can be selected. Further, the system control unit 120 is in a state where the cancel button 708 for canceling the change instruction can be selected at any time.

  Returning to FIG. 9, the flow description will be continued. When the OK button 707 is selected in step S308, the processed pre-image and the shooting condition instructed to change by the setting item are transmitted to the camera 200 as a change instruction signal. Therefore, the request terminal 100 completes the formal request processing by sequentially transmitting the formal request signal and the change instruction signal to the camera 200, and proceeds to step S116 in FIG.

  When the camera 200 receives the change instruction signal in step S310, the system control unit 250 displays the processed pre-image and the change-instructed setting item on the display unit 201, and performs an operation for changing the imaging condition to the imaging acceptor. Prompt. Alternatively, the system control unit 250 may automatically set the shooting conditions in accordance with the contents of the change instruction signal. For example, it is more efficient to automatically set the color temperature according to the value that the photographing client moves the slide bar 705 than to change the instruction regarding the white balance by operating the operation member 202 by the photographing acceptor. is there.

  In step S <b> 311, the system control unit 250 executes the main photographing process using the operation of the release switch 211 of the photographing acceptor as a trigger. In the main photographing process, the system control unit 250 causes the exposure control unit 246 to operate the lens shutter 224 according to the determined exposure value, and guides the subject light flux to the image sensor 231. In step S312, the photoelectrically converted image signal is processed by the image processing unit 237 to generate captured image data. The system control unit 250 stores the captured image data generated in this way in the internal memory 235. In this way, the system control unit 250 of the camera 200 completes the shooting operation process and proceeds to step S210 in FIG.

  Next, the reward changing process according to step S118 of FIG. 7 will be described in detail. FIG. 10 is a diagram illustrating a flow of the reward change process by the request terminal 100. The photographed image data received from the photographing acceptor's camera 200 as a result of the photographing request by the requesting terminal 100 may be better than expected or may be disappointing. Therefore, the request terminal 100 provides an opportunity to change the return condition according to the quality of the received captured image data.

  In step S401, the system control unit 120 checks the elapsed time of the timer started in step S116. It is preferable for the client who wants to take a short time from when the photographing is officially requested until when the photographed image data is received. Next, in step S402, image analysis of the captured image data received by the image analysis unit 131 is performed. The image analysis is executed according to items in a return change evaluation table described later.

  Then, the system control unit 120 displays the received captured image data on the display unit 101 in step S403. The photographer evaluates the performance by observing the photographed image displayed on the display unit. In step S <b> 404, the system control unit 120 accepts the evaluation of the imaging client. Thus, the captured image data is evaluated from various angles, and in step S405, the system control unit 120 changes the viewing condition according to the evaluation, ends the series of viewing change processing, and proceeds to step S119.

  FIG. 11 is a diagram illustrating an example of the reward change evaluation table. The table is divided into three categories for each evaluation item: points added, no changes, and points deducted. For example, the added points can be associated with +50 points and the deducted points can be −20 points, or the weight of the added points and deducted points can be changed for each evaluation item.

  As the elapsed time, for example, within 3 minutes can be added, and from 3 minutes to 10 minutes can be changed, and 10 minutes or more can be set as a deduction target. The shake state, the focused state, the exposed state, and the face recognition are evaluation items analyzed by the image analysis unit 131. For example, in the evaluation of the in-focus state, an image in which only the focus point is focused and the background is beautifully blurred is regarded as a target for addition. Further, in the evaluation of the exposure state, if spot metering is selected and the main subject has a proper exposure, the target is added. That is, photographic image data that has been photographed appropriately even though the degree of photographing difficulty is high is regarded as a target for addition. Further, depending on whether or not the desired person to be photographed 406 included in the photographing request signal and notified to the photographing acceptor in advance is shown, and whether or not the person's face is in focus, the points to be added or reduced Become. In addition, if the evaluation input by the photographing client in step S404 is high, a point is added. The evaluation input by the client is represented by the number of stars, for example.

  As described above, the embodiment for requesting the shooting of a still image has been described. Of course, a movie shooting may be requested. In addition, although the explanation has been given centering on the shooting request where the shooting requester uses the subject as a subject, the subject may be any scene. The present embodiment can be applied even in a situation where the photographing requester and the photographing acceptor are not close to each other. For example, a photographing client who is in a remote location can request a candidate who is present at the event to photograph a specific event. In such a case, mutual communication may be performed via the network 300 or the like instead of performing mutual communication by the short-range communication module.

  As mentioned above, although this invention was demonstrated using embodiment, the technical scope of this invention is not limited to the range as described in the said embodiment. It will be apparent to those skilled in the art that various modifications or improvements can be added to the above-described embodiment. It is apparent from the scope of the claims that the embodiments added with such changes or improvements can be included in the technical scope of the present invention.
