Description

  The present invention relates to a photographing support system for presenting photographing support information such as a recommended position for photographing to a user.

  There is a photographing support system that provides position information of a specific subject to a photographer (Patent Document 1). In this prior art, an IC tag or an infrared transmitter that can be identified for each subject is possessed, and the location of the specific subject is presented to the photographer. Therefore, the photographer can easily grasp the position of a specific subject when photographing his / her child at an athletic meet, for example.

  On the other hand, there is a service in which a photographer photographs an event such as a wedding and creates a photo book or the like.

JP 2008-066963 A

  In the event photobook creation service as described above, when shooting, not only a specific subject but all event participants are required to be shot uniformly. Therefore, the conventional technology that provides only the position of a specific subject may not always be suitable as shooting support when creating a photobook such as a wedding.

  For example, in the prior art, when a person who has a shortage of shots or when a specific subject should be shot at a certain time, the ID of that person must be specified. However, when a person who does not grasp all the event participants performs shooting, it is difficult to specify a person whose shooting number is insufficient, a name of a person to be shot, and the like. Also, for example, when it is desired to shoot all event participants uniformly, the cameraman must shoot efficiently within a limited time such as a wedding. In the prior art, the photographer must arbitrarily designate a specific subject based on his / her own judgment, and position information that enables efficient shooting is not taken into consideration.

  SUMMARY OF THE INVENTION In view of the above-described problems, an object of the present invention is to provide shooting support that presents a shooting position and direction so that a photographer can efficiently perform shooting. A shooting support system for supporting shooting in a shooting apparatus, wherein a first acquisition unit that acquires a position of a shooting target, a determination unit that automatically determines a shooting target to be shot, and the determination unit A second acquisition unit that acquires a shooting position at which the shooting target is shot based on the position acquired by the first acquisition unit; and a presentation unit that presents the shooting position to the photographer. Provide a shooting support system.

  According to the present invention, since the photographing target to be photographed is automatically determined and the photographing position of the photographing target is presented to the photographer, it is possible to support the photographer for efficient photographing.

  Hereinafter, the present invention will be described in detail based on preferred embodiments with reference to the accompanying drawings. The configurations shown in the following embodiments are merely examples, and the present invention is not limited to the illustrated configurations.

<Embodiment 1>
In the first embodiment, the photographer is presented with positional information of a photographing target to be photographed in order to efficiently photograph an event based on photographing conditions such as a photographing target photographed in the past and its composition. FIG. 1 is a block diagram showing a configuration of a photographing support system according to an embodiment of the present invention. In this embodiment, the wireless communication is possible among the photographing apparatus 101, the server 104, and the identification apparatus 103 shown in FIG. That is, wireless communication is performed between the receiving units (117, 143) and the transmitting units (116, 133, 142) in FIG. 1, and data can be transmitted and received between them.

  The photographing apparatus 101 is an apparatus that can photograph an image such as a camera. The database 102 is a storage device such as an HDD, and is controlled by the server 104 and can store various data such as information on the current position of the photographing device 101 and each identification device 103. The identification device 103 is a portable terminal device having a function such as RFID (Radio Frequency Identification), and is used for the purpose of identifying a subject to be imaged. It is assumed that a person or an object to be photographed has this device individually. In the present embodiment, the photographing support system is configured to be able to identify the current positions and orientations of the photographing device 101 and the respective identifying devices 103. The server 104 transmits and receives data with the imaging apparatus 101 and the identification apparatus 103 through communication. The server 104 is an information processing apparatus that creates shooting support information and provides the created shooting support information to the shooting apparatus 101. The server 104 reads and writes data from and to the database 102.

  FIG. 1A is a block diagram illustrating a configuration of a photographing support system used in the first embodiment. A configuration of the imaging apparatus 101 will be described. The photographing apparatus 101 has an arithmetic device such as a CPU, and controls the entire device, calculates information, processes, etc. based on a program held in a storage device such as a ROM, and executes processing described later. A presentation unit 111 outputs photographing support information using a display or a speaker installed in the photographing apparatus and performs a process of presenting the information to the user. Reference numeral 112 denotes a designation unit that accepts designation of a subject for which shooting support information is to be obtained from a plurality of subject candidates based on input from an operation button or the like from a user. Reference numeral 113 denotes a position / orientation acquisition unit that performs processing for detecting the direction facing the current position of the image capturing apparatus 101 and acquiring it as data. As a method for detecting the current position / direction, for example, a method using a plurality of camera images (Japanese Patent No. 4046186) or a method using wireless communication (RFID) (Japanese Patent Laid-Open No. 2008-3077) is used. Can be used. Moreover, you may use what uses GPS (Global Positioning System) or a gyro sensor.

  In the present embodiment, the configuration is such that the photographing apparatus 101 itself acquires the direction facing the current position, but the server 104 may calculate and acquire the position of the photographing apparatus 101. In this case, for example, the server 104 can acquire the position information of the photographing apparatus 101 based on data by wireless communication from the photographing apparatus 101.

  Reference numeral 114 denotes a storage unit which holds, for example, function information such as specifications of the photographing apparatus such as maximum zoom magnification and focal length and apparatus information such as setting information such as the currently set angle of view. An imaging unit 115 includes an image sensor such as a CCD that receives light passing through a lens and converts it into an electric signal, and an A / D converter that converts an electric signal obtained by the image sensor into a digital signal. . The photographing unit 115 performs processing for generating image data from a digital signal.

  The configuration of the identification device 103 will be described. Reference numeral 131 denotes a subject position / orientation acquisition unit that performs processing for detecting the direction facing the current position of the identification device and acquiring it as data (first acquisition). The method for detecting the current position / direction is the same as that of the position / orientation acquisition unit 113 described above. An ID storage unit 132 holds an identifier, and the ID information of the identifier is information unique to each identification device 103. This makes it possible to distinguish from other identification devices. The server 104 may acquire the position of the identification device 103 (first acquisition) based on data from the identification device 103 through wireless communication.

  The configuration of the server 104 will be described. The server 104 is an information processing apparatus having an arithmetic device such as a CPU, and controls the entire device, calculates information, processes, etc. based on a program held in a storage device such as a ROM, and executes processing described later. Reference numeral 141 denotes a creation unit that acquires necessary data from the database 102 and acquires a shooting position / direction suitable for shooting a subject (second acquisition), and generates shooting support information. Reference numeral 142 denotes a transmission unit that outputs and transmits data such as photographing support information to the photographing apparatus 101. Reference numeral 143 denotes a receiving unit that receives data such as position information from the photographing apparatus 101 and the identification apparatus 103. Reference numeral 144 denotes an evaluation unit that automatically evaluates whether to shoot each shooting target based on the shooting situation of the shooting target taken by the shooting apparatus 101 or the shooting situation such as the shooting time when the shooting apparatus 101 takes a shot. .

  Next, an operation example of the photographing support system according to the present embodiment having the above-described configuration will be described. FIG. 2 schematically shows the order of processing performed in this system. In this system, first, subject candidate registration processing S01 is performed. This is processing for previously registering identification information (subject ID) of a candidate (photographing target) that can be a subject of photographing in the server. For example, when photographing a wedding participant, subject IDs of all the participants are registered.

  Next, the imaging device information update process S02, the subject information update process S03, and the imaging support information presentation process S04 are executed in parallel. The imaging device information update process S02 is a process for recording the current position and direction of the imaging device in real time so that the server 104 can recognize them. The subject information update process S03 is a process for recording the current position / direction of the identification device 103 in real time so that the server 104 can recognize it. By this processing, the server 104 can grasp the current positions and directions of all the photographing objects in real time. The photographing support information presentation processing S04 performs processing for presenting photographing support information such as a location and direction suitable for photographing a subject to the photographer. The processing of S02 to S04 is performed in real time while the photographer is photographing, and is repeatedly executed until the system is terminated by turning off the power of the apparatus.

  Next, each process of S01 to S04 will be described in detail below. FIG. 3 is a flowchart showing subject candidate registration processing S01. First, the identifier held by the identification device 103 is transmitted to the server (S0101). The server 104 receives and acquires the identifier (S0102). The server 104 determines whether the identifier held by the received identification device 103 is already registered with reference to the database 102 (S0103). If not registered, the acquired identifier and the ID (subject ID) such as the name of the subject to be photographed possessing the identification device 103 are registered in association with the database 102 (S0104). Subsequently, the server 104 notifies the identification device 103 that the registration is completed, and ends the registration process (S0105). In S0103, if the received identifier has already been registered in the database 102 in association with the subject ID, the server 104 performs only a completion notification (S0105). The identification device 103 determines whether or not a completion notification has been received, and if received, ends the registration process (S0106). The above registration process is repeated for all subjects to be imaged.

  Note that, as described above, the identification device 103 individually has a person to be photographed one by one. Therefore, for example, in the case of wedding photography, the identification device 103 is distributed to each participant one by one before the start of photographing, and the subject to be photographed always carries the identification device 103 during the ceremony.

  Next, FIG. 4 is a flowchart showing the photographing apparatus information update process S02. The position / orientation acquisition unit 113 of the imaging apparatus 101 acquires the current position / orientation (S0201). Then, the transmission unit 116 transmits the current position / orientation of the imaging device 101 to the server together with the device information held by the storage unit 114 (S0202). The device information is information such as the maximum zoom magnification value that can be taken by the camera and the currently set angle of view.

  On the other hand, the server 104 is in a standby state for receiving data from the photographing apparatus 101 (S0203). When the receiving unit 143 of the server 104 receives data from the imaging apparatus 101, the server 104 determines whether these data are different from the values recorded in the database 102 (S0204). The server 104 records and updates the received data value when the received data is different from the recorded data and when the data is not recorded in the database 102 (S0205). Then, the process ends.

  The imaging device information update process S02 described above is repeatedly executed at regular intervals, whereby real-time location / orientation information of the imaging device is recorded in the database 102. Therefore, the server 104 can acquire the current position and the like of the photographing apparatus 101 in real time.

FIG. 5 is a flowchart showing subject information update processing S03.
The identification device 103 acquires the current position / orientation by the subject position / orientation acquisition unit 131 (first acquisition) (S0301). Then, the transmission unit 133 transmits the current position / orientation of the identification device 103 to the server 104 together with the ID (identifier) held by the ID storage unit 132 (S0302).

  On the other hand, the server 104 is in a standby state for receiving data from the identification device 103 (S0303). When the receiving unit 143 of the server 104 receives data from the identification device 103, the server 104 determines whether these data are different from the values recorded in the database 102 in association with the ID of each identification device 103. (S0304). When the received data is different from the recorded data or when no data is recorded in the database 102, the server 104 records and updates the received data value (S0305). Then, the process ends.

  As described above, the subject information update processing S03 is continuously executed for each identification device 103 at regular intervals, and thereby, real-time position / orientation information of the imaging device is recorded in the database 102. Therefore, the server 104 can acquire the current position and the like of the identification device 103 in real time (first acquisition).

  FIG. 6 is a flowchart showing the photographing support information presentation process S04. The photographing apparatus 101 is always in a reception standby state for photographing support information during photographing. In the reception standby state of the photographing support information, the designation unit 112 determines whether or not there is an input from the photographer (S0401). When the photographer wants to obtain shooting support information for a specific subject, the photographer inputs to the designation unit 112. On the other hand, if shooting of a specific subject is not intended and efficient shooting is desired, input to the designation unit 112 is not performed, and shooting support information of a shooting target to be shot can be acquired from the system. When the designation unit 112 determines that there is an input from the user, the designation unit 112 requests the server 104 for a list of subjects to be photographed (S0402). If there is no input from the photographer to the designation unit 112, the photographing apparatus 101 maintains a reception standby state for photographing support information (S0408).

  The server 104 always determines whether or not a subject list request has been received (S0403). If the server 104 determines that it has received the subject list request, it executes the process of S0404 as an interrupt process. When the subject list request is received, the creation unit 141 reads information on subjects to be photographed registered from the database 102 and creates subject list data. In the subject list data, all subject IDs registered in the registration process are described. The transmission unit 116 transmits the created subject list data to the photographing apparatus 101 (S0404). Upon receiving the subject list data, the photographing apparatus 101 displays the subject list data acquired by the presentation unit 111 on, for example, a display and presents it to the photographer (S0405). The photographer selects the subject ID of the subject to be photographed for which photographing support information is desired from the subject list data using an operation button (not shown). The designation unit 112 acquires input of the subject ID designated by the photographer (S0406). Subsequently, the transmission unit 116 of the photographing apparatus 101 transmits the designated subject ID to the server 104 (S0407). When the photographing apparatus 101 finishes transmitting the subject ID, the photographing apparatus 101 enters a reception standby state for photographing support information (S0408). Upon receiving the designated subject ID, the server 104 stores the ID in a storage device such as a RAM (S0409).

  On the other hand, in S0403, if the server 104 does not receive a subject list request (request for shooting support information specifying a subject), the server 104 evaluates each shooting target to automatically determine a shooting target to be shot (S0410). Here, the evaluation of the shooting target is performed based on the past shooting situation of the subject to be shot. In this embodiment, a point value is calculated for each object to be imaged, and evaluation is performed based on the point value.

  Here, the provision of the point value based on the shooting situation will be described. For example, when creating a photo book, it is preferable to use an image at the center position for each subject to be photographed. Therefore, it is desirable to capture an image in which each subject to be imaged is at the center position. That is, the evaluation unit 144 recognizes the subject in the photographed image, and accumulates from the photographed images taken in the past for each subject to be photographed, such as three points for the center position and one point for other than the center. To calculate points. It should be noted that, in order to actively support shooting at the leading role or the host (groom or bride if it is a wedding), it may be configured to calculate fewer points than other shooting targets. . In addition, you may change the provision method of a point value according to the objective. Other than the above, for example, a low point value is given only for a specific shooting time to a specific shooting target. If points are calculated using this point value assignment method, for example, it is possible to provide appropriate support for a request to preferentially shoot a situation in which a presiding official is speaking at a wedding, for example. Become.

  As described above, the evaluation unit 144 calculates a point value based on the shooting situation such as past shooting and shooting time for shooting. The evaluation unit 144 performs evaluation regarding which shooting target should be shot based on the point value. Then, the evaluation unit 144 evaluates that shooting support regarding the shooting target with the lowest point value should be performed, and the server 104 acquires the subject ID of the shooting target with the lowest point. The server 104 determines the photographing target having the lowest acquired point as a designated subject for creating photographing support information (S0411). When there are a plurality of shooting targets having the same lowest point value, a shooting target close to the shooting apparatus 101 is determined as the designated subject.

  Subsequently, the server 104 acquires (first acquisition) from the database 102 the current position / direction of the imaging target corresponding to the subject ID specified in S0409 and S0411 and the current position / direction of the imaging apparatus 101 (S0412). . The server 104 calculates and acquires a position / direction suitable for shooting of the shooting target based on the acquired position information of the shooting target (second acquisition) (S0413). Here, the position / direction suitable for photographing is a place away from the current location of the subject by an appropriate distance (photographing distance) along the direction in which the subject is facing. Here, it is assumed that the value of the shooting distance is determined in advance such as 3 m and recorded in the database 102. Further, an optimum shooting distance may be calculated and acquired (second acquisition) based on the maximum zoom magnification of the shooting apparatus 101 and the position of the subject that is another shooting target (second acquisition). For example, when the maximum zoom magnification is 3, the shooting distance may be calculated and acquired (second acquisition) up to 9 m, which is 3 times as large as 3 m in the case of 1 time. Moreover, it is good also as a structure which calculates and acquires (2nd acquisition) an appropriate imaging distance based on all the present positions of imaging | photography object. For example, it is not calculated as a shooting position at which another person gets in the way when shooting a subject to be shot. With such a configuration, it is possible to provide a photographer with a photographing position suitable for photographing, so that it is possible to support efficient photographing.

  The creation unit 141 acquires (second acquisition) the current position / direction of the shooting target determined from the database 102, and calculates position coordinates separated by the shooting distance in the direction of the shooting target. This coordinate position is set as a recommended shooting position. In addition, a direction opposite to the direction of the subject to be photographed is calculated from the recommended photographing position. This direction is the recommended shooting direction. Although the recommended shooting position is a single coordinate, it may be a section coordinate having a width. For example, the recommended shooting position of a certain subject may be on the circumference with the shooting distance as the radius around the subject.

  Subsequently, the creation unit 141 creates shooting support information based on the calculated recommended shooting position and recommended shooting direction (S0414). The creation unit 141 generates map-like image data and audio information representing the recommended shooting position and recommended shooting direction as shooting support information. The transmission unit 142 transmits (outputs) the created imaging support information to the imaging apparatus 101 (S0415).

When the photographing apparatus 101 determines that the photographing support information has been received (S0408),
The presenting unit 111 outputs the received photographing support information and presents it to the photographer (S0416). FIG. 7 shows an example of presentation of photographing support information by the photographing apparatus 101. Reference numeral 701 denotes an example of a display screen when shooting support information is displayed on a display included in the shooting apparatus 101. The display example 701 is a map schematically showing the entire shooting venue viewed from above. Reference numeral 702 denotes the current position / direction of the photographing apparatus 101. Reference numeral 703 denotes a recommended shooting position and recommended shooting direction. Reference numeral 704 denotes a route guide display from the current position to the recommended shooting position. By looking at the arrow guide display, the photographer can easily determine which position in which direction to go from now on. Reference numeral 705 denotes the current position / direction of the photographing target that is the designated subject.

  Further, guidance from the current position of the photographing apparatus 101 to a recommended photographing position may be presented to the photographer as audio data. For example, the photographer may be supported by taking a voice so that “a place where the person advances to the right 2 m from the current position and faces 45 degrees diagonally left is recommended”.

  FIG. 8 is an example of presentation when only the recommended shooting position is presented. Reference numeral 801 denotes an example of a display screen when shooting support information is displayed on a display included in the shooting apparatus 101. Reference numeral 802 denotes a current position of the photographing apparatus 101, reference numeral 803 denotes a recommended photographing position, and reference numeral 804 denotes a current position / direction of a photographing target that is a designated subject. The recommended shooting position is on the circumference centered on the subject as indicated by reference numeral 803. The photographer may go to somewhere on this circumference and take a picture.

  As described above, the photographing support information is presented to the photographer. Next, the photographing apparatus 101 determines whether photographing has been completed by detecting the pressing of a shutter button (not shown) (S0417). The shooting support information continues to be presented until the shutter button is pressed. When the photographing apparatus 101 detects that the shutter button is pressed, the photographing apparatus 101 notifies the server 104 that photographing has been completed (S0418).

  Upon receiving the shooting completion notification (S0419), the server 104 updates the evaluation condition (S0420). The server 104 acquires from the database 102 the position information of the imaging device 101 and the imaging target at the imaging time when the imaging was performed. Note that the current position / direction of the image capturing target and the current position / direction of the image capturing apparatus 101 are always up-to-date by the subject information update process S03 and the image capturing apparatus information update process S02. Also, apparatus information of setting information such as the currently set angle of view of the photographing apparatus 101 is also acquired. Based on the acquired information, the photographing range of the photographing apparatus 101 at the photographing time when photographing is performed is calculated. Furthermore, the subject included in the photographing range and the position on the image are calculated. The evaluation unit 144 updates the point value of the subject included in the captured image based on the calculation result and the point calculation condition. In addition, you may identify the imaging | photography target reflected in a picked-up image using a face recognition process. In this case, the face image to be photographed is stored in the database 102 before photographing. Then, the image capturing apparatus 101 transmits the captured image data to the server 104 together with the image capturing completion notification performed in S0418. Then, in the server 104, using the face image of the shooting target stored in the database 102, the shooting target that appears in the shot image is identified by a known face recognition process. And you may comprise so that evaluation conditions (point value) may be updated. The above photographing support presentation process is repeatedly executed while photographing is being performed.

  As described above, according to the present embodiment, which shooting target is to be shot is evaluated, and shooting position information of the shooting target to be shot automatically determined by the evaluation is presented to the photographer. Therefore, it is not necessary to designate a specific shooting target, and for example, it is possible to provide the shooting person with a shooting position where shooting required for creating a photo book can be performed efficiently. Further, since the system automatically evaluates the subject to be photographed, it is not necessary for the photographer to make a photographing plan. In addition, since the photographer is presented with the position and orientation suitable for the photographing of the photographing target to be photographed based on the evaluation, the photographer does not need to recognize the face or the like of the photographing target. In addition, the evaluation of the shooting target to be shot is performed based on the shooting situation such as past shooting and shooting time. Therefore, even when shooting events such as weddings that are performed for a limited time, the recommended shooting position of the shooting target to be shot is presented to the photographer, so the necessary photos can be shot efficiently. Can help to make it happen. In addition, since the photographer can specify a specific photographing target and acquire photographing position information suitable for photographing the photographing target, it is convenient for the photographer. In addition, since the guide of the route to the recommended shooting position is also presented, the photographer can easily go to the recommended shooting position.

  Note that the image data and audio data are transmitted to the image capturing apparatus 101 as the image capturing support information. However, the image capturing apparatus 101 may generate image data and audio data by using only the image capturing support position as the image capturing support position.

<Embodiment 2>
In the first embodiment, an evaluation of a shooting target to be shot is performed using a point value. In the second embodiment, the shooting target to be shot is evaluated according to the number of shots of each shooting target. In the present embodiment, for example, it is possible to perform shooting support suitable for shooting all participants evenly at a wedding.

  Differences from the first embodiment will be described. In the present embodiment, the number of shots is managed in the database 102 for each shooting target registered in the subject candidate registration process S01. In the subject evaluation process in S0410, the server 104 refers to the database 102 and acquires the number of shots for each shooting target.

  In step S0411, the evaluation unit 144 evaluates that the shooting target with the smallest number of shots should be shot, obtains the ID of the shooting target, and determines it as the designated subject. When there are a plurality of shooting targets with the same number of shots, the youngest subject ID number may be selected, selected randomly, or determined as the shooting target closest to the shooting apparatus 101. .

  When the server 104 presents shooting support information regarding the designated subject to the photographer and receives a shooting completion notification, the server 104 updates the number of shots of the subject ID in the shot image by adding 1 in S0420. In this way, the number of shots for each shooting target is registered in the database.

  In this way, shooting support information is presented in order from the subject with the fewest number of shots. Therefore, if the photographer shoots according to the shooting support information, the variation in the number of shots for each subject can be suppressed without being aware of it. it can.

  In the above description, one of the shooting targets with the smallest number of shots is set as a target for creating shadow support information. However, a plurality of shooting targets may be set as targets. That is, for example, the recommended shooting positions and directions for five people who have a small number of shots may be presented at the same time. In this case, in step S0410, the top five shooting targets with a small number of shots are selected and their subject IDs are acquired from the database 102. Then, shooting support information for all acquired subject IDs may be created and presented to the photographer. Furthermore, when presenting a plurality of shooting targets with a small number of shots, the shooting targets may be presented in order from the shortest distance from the photographer. In this case, in S0412, the distance from the imaging device 101 is calculated for all of the plurality of imaging targets with a small number of images. Then, a shooting target closest to the shooting device 101 may be selected, shooting support information regarding the shooting target may be created, and presented to the photographer. Since the photographer can sequentially photograph the photographing objects with a small number of photographs in the vicinity, the moving distance is small and the photographing can be performed efficiently.

<Embodiment 3>
In the third embodiment, map information in a shooting venue (shooting location) is registered, and a recommended shooting position is provided in consideration of the shooting venue (shooting location). Differences from the first embodiment will be described. FIG. 1B is a block diagram of the photographing support system used in the present embodiment. Differences from FIG. 1A will be described. A registration unit 145 of the server 104 shown in FIG. 1B registers map information of the shooting venue (shooting location) in the database 102 based on user input.

  FIG. 9 schematically shows the processing order of the system in this embodiment. The shooting venue map information registration process S05 is added to the procedure of FIG. This shooting venue map information registration process is executed in parallel with the subject candidate registration process S01. In the shooting hall map information registration process S05, position information of an object that is an obstacle to shooting existing in the shooting hall (shooting place) is registered in the database 102. For example, in the case where a light is installed in the venue, if photographing is performed toward the light source of the light, the light is backlit and appropriate photographing cannot be performed. Therefore, in the shooting venue map information registration process, the position coordinates of the light and the range of light illuminated by the light are registered. These values are set in advance by the user before shooting.

The shooting support information presentation process S04 in the present embodiment, which is executed when shooting is performed after the shooting venue map information registration process S05 described above, is described. In S0413 of the shooting support information presentation process shown in FIG. 6, the recommended shooting position / direction is calculated as in the first embodiment. Here, FIG. 10 is a diagram schematically showing a shooting venue for explaining a method of calculating a recommended shooting position based on map information in the present embodiment. Reference numeral 1001 in FIG. 10 is a map schematically showing a shooting venue (shooting location). Reference numeral 1002 denotes a recommended shooting position calculated in the first embodiment. Here, it is assumed that the position coordinates of the recommended shooting position 1002 are (x, y). Reference numeral 1003 denotes the position of the designated subject that is the target of photographing support. Reference numeral 1004 denotes the position of the light registered in the shooting venue map information registration process. Here, let the position coordinates of the light be (X _L , Y _L ). Also. _{(Θ 0 ~θ 0 + θ T} ) in the figure shows the range of light of the light. In S0413 in the present embodiment, the server 104 determines whether the position (x, y) of the recommended shooting position 1002 is within the range of light illuminated by the light and whether the recommended shooting direction faces the light.

When the expressions (1) and (2) are satisfied, the position (x, y) exists within the range illuminated by the light. If the position (x, y) is within the range illuminated by the light, the server 104 newly calculates a recommended shooting position outside the range illuminated by the light and not facing the light. For example, equal to the position of the photographing recommended positions 1002 calculated without considering obstacles and the distance between the position of the specified object, it calculates a theta ₀ positions less than or θ _{0 +} θ _T is greater than the position, photographing recommended position this 1005 And decide. Since there may be a plurality of such recommended shooting positions, the recommended shooting positions may be presented as areas.

  Note that the description has been made assuming that an object that obstructs photographing is a light, but the present invention is not limited to this. For example, it is good also as a structure which registers obstructions, such as a pillar. Furthermore, the position information registered as map information has been described as an object that is an obstacle to shooting, but it is also possible to register the floor plan information of the shooting venue (shooting location). By registering map information such as a floor plan, it is possible to provide a recommended shooting position even for shooting targets in different rooms. Further, the route guide to the recommended shooting position described in the first embodiment can be performed in consideration of the floor plan, and the route guide considering the entrance to the room and the like can be provided.

  As described above, in this embodiment, it is possible to present the photographer with a recommended shooting position that is not affected by an obstacle. Accordingly, it is possible to provide the photographer with a position where appropriate photographing can be performed, so that the efficiency of photographing can be improved.
