(First embodiment)
Hereinafter, an imaging system 1 which is a specific example of the present invention will be described as a first embodiment. The imaging system 1 is arranged, for example, in a beauty salon or barber shop, and is used to generate multi-view image data indicating a multi-view image of the upper body of a customer who has finished haircut or hair set.

  FIG. 1 is a diagram schematically illustrating the appearance of the imaging system 1. The imaging system 1 includes an imaging device holding fixture 11 and an imaging device 12. FIG. 1 also shows a subject 9 that is a person imaged by the imaging device 12. In the following description, “front” and “rear” mean “front” and “rear” as viewed from the subject 9 in FIG.

  First, the imaging device holding tool 11 is fixed to the base 1101 so as to extend vertically upward from the base 1101 and a base 1101 that is a disk-like member that is placed on the floor and supports the main body of the imaging device holding tool 11. A lower holding member 1102 that is a pipe, and an upper holding member 1103 that is a member obtained by bending a pipe having an outer diameter slightly smaller than the inner diameter of the lower holding member 1102 twice as indicated by the numeral “7” at 90 degrees. It has.

  On the lower surface of the base 1101, for example, a plurality of casters for smooth movement of the imaging device holding tool 11 on the floor surface are attached.

  Of the two pipe portions extending in the vertical direction of the upper holding member 1103, the lower end portion of the longer one (the left portion in FIG. 1, hereinafter referred to as “rear vertical portion”) is the hollow portion of the lower holding member 1102. The lower holding member 1102 is connected to the upper side of the upper holding member 1103.

  A fastening member 1104 that adjusts the vertical position of the upper holding member 1103 with respect to the lower holding member 1102 is provided at a connection portion between the lower holding member 1102 and the rear vertical portion of the upper holding member 1103. The fastening member 1104 is, for example, a cylindrical member having a thread valley cut on the inner surface so as to be screwed into a screw thread cut on the outer surface of the upper end portion of the lower holding member 1102. A plurality of cuts are provided at the upper end of the lower holding member 1102 so as to penetrate the pipe for a predetermined length from the end face downward.

  Therefore, when the tightening member 1104 is rotated clockwise as viewed from above, the upper end portion of the lower holding member 1102 is tightened, and the lower end portion of the upper holding member 1103 inserted inside the lower holding member 1102 is tightened to the lower holding member. By tightening 1102, the upper holding member 1103 is fixed to the lower holding member 1102. The user turns the fastening member 1104 counterclockwise to loosen the fastening of the lower holding member 1102 with respect to the upper holding member 1103, moves the upper holding member 1103 in the vertical direction, determines the position thereof, and then moves the fastening member 1104 By rotating it clockwise, the vertical position of the upper holding member 1103 can be adjusted.

  Of the two pipe portions extending in the vertical direction of the upper holding member 1103, the lower end of the shorter one (the right portion in FIG. 1, hereinafter referred to as “front vertical portion”) is the lower end that is a disk-shaped member. The member 1105 is connected by, for example, screwing. The lower end member 1105 is a ball bearing having a number of freely rotating balls arranged in a circle around a disc-shaped center, and the balls are exposed on the upper surface side.

  On the upper side of the lower end member 1105, an arm base 1106, which is a donut-shaped member, is placed in a state where the front vertical portion of the upper holding member 1103 passes through a hole opened in the center thereof. The diameter of the arm base 1106 is the same as the diameter of the lower end member 1105, and the diameter of the hole formed in the arm base 1106 is slightly larger than the outer diameter of the front vertical portion of the upper holding member 1103. With the structure as described above, the arm base 1106 can freely rotate around the central axis of the front vertical portion of the upper holding member 1103 on the ball bearing of the lower end member 1105.

  A front arm 1107, which is a pipe extending in the horizontal direction, is connected to the side surface of the arm base 1106. On the inner side of the end of the front arm 1107 opposite to the side connected to the arm base 1106, a pipe having an outer diameter slightly smaller than the inner diameter of the front arm 1107 is bent once at 90 degrees to be an “L” shape. One end of a front angle 1108, which is a shaped member, is inserted.

  A fastening member 1109, which is a cylindrical member having a thread valley cut on the inner side surface, is connected to the front arm 1107 and the front angle 1108, and is a screw cut on the outer side surface of the end portion of the front arm 1107. It is arranged so as to screw into the mountain. The end of the front arm 1107 connected to the front angle 1108 is provided with a plurality of cuts penetrating the pipe over a predetermined length in the horizontal direction from the end surface toward the arm base 1106.

  The user adjusts the horizontal position of the front angle 1108 relative to the front arm 1107 with the tightening member 1109 in the same manner as when adjusting the vertical position of the upper holding member 1103 relative to the lower holding member 1102 with the tightening member 1104. be able to.

  Normally, as shown in FIG. 1, the front angle 1108 is fixed to the front arm 1107 so that the longitudinal direction of the portion not connected to the front arm 1107 is a vertical direction when viewed from the bent position. Hereinafter, a portion of the front angle 1108 having the horizontal direction as the longitudinal direction is referred to as a “horizontal portion”, and a portion having the vertical direction as the longitudinal direction is referred to as a “vertical portion”.

  A holder 1110, which is a member that holds the imaging device 12 in an upright state, is attached to the lower end portion of the vertical portion of the front angle 1108. The direction of the holder 1110 with respect to the front angle 1108 is adjusted so that the imaging direction of the camera of the imaging device 12 faces the axial direction of the front vertical member of the upper holding member 1103 while being held by the holder 1110.

  A pipe bent in an “L” shape so that it extends in the horizontal direction and then extends vertically downward at a position on the opposite side of the side of the arm base 1106 to which the front arm 1107 is connected. A certain rear angle 1111 is connected. Hereinafter, similarly to the front angle 1108, a portion of the rear angle 1111 having the horizontal direction as the longitudinal direction is referred to as a “horizontal portion”, and a portion having the vertical direction as the longitudinal direction is referred to as a “vertical portion”.

  A background plate 1112 that is a wide plate-like body is attached to the lower end portion of the vertical portion of the rear angle 1111. The background plate 1112 is curved so as to form a part of a side surface of a column that is generally centered on the longitudinal direction of the vertical portion of the front angle 1108.

  A weight 1113 that is a ring-shaped member is attached to the front arm 1107 so that the front arm 1107 passes through the hole. The diameter of the hole of the weight 1113 is substantially the same as the outer diameter of the front arm 1107.

  The weight 1113 is fixed to the horizontal direction of the front arm 1107 by, for example, a frictional force. Therefore, the user applies a force larger than the friction force to the weight 1113 in the direction along the longitudinal direction of the horizontal portion of the rear angle 1111 so that the weight 1113 is positioned in the horizontal direction with respect to the front arm 1107. Can be adjusted freely.

  On the upper surface of the arm base 1106, a level device 1114 is attached for the user to check whether or not the longitudinal direction of the horizontal portions of the front arm 1107 and the rear angle 1111 is the horizontal direction. The level device 1114 includes, for example, a glass tube filled with colored oil containing bubbles. The glass tube of the level device 1114 is arranged so that the longitudinal direction thereof is the horizontal direction. When the longitudinal direction of the horizontal portion of the front arm 1107 and the rear angle 1111 coincides with the horizontal direction, the bubbles in the oil are glass. It is adjusted to be located at the center in the longitudinal direction of the tube.

  When the user moves the horizontal position of the weight 1113, the inclination of the arm base 1106 connected to the front arm 1107 with respect to the horizontal plane changes according to the weight balance. The user can adjust the horizontal position of the weight 1113 so that the bubble of the leveler 1114 is positioned at the center of the glass tube, thereby taking the horizontal direction of the front arm 1107 and the rear angle 1111 in the longitudinal direction.

  On the lower surface of the lower end member 1105, a laser pointer 1115 is attached. The laser pointer 1115 irradiates a laser beam toward the lower part of the central axis of the front vertical portion of the upper holding member 1103. The laser pointer 1115 is provided with a switch for turning on / off the irradiation of the laser beam, and a battery as a power source is incorporated.

  A sound generator 1116 that emits a sound having a predetermined waveform every time the arm base 1106 rotates 10 degrees from the reference position with respect to the lower end member 1105 is attached to the holder 1110.

  For example, a switch mechanism as shown in FIG. 2 is provided on the lower end member 1105 and the arm base 1106 in order to cause the sound generator 1116 to generate sound.

  That is, the upper surface of the lower end member 1105 is entirely covered with an insulator, and a conductor 1117 extending at a predetermined length in the diametrical direction at intervals of 10 degrees around the center of the disk shape is totaled 36 on the cover. Individually arranged so as to line up on the circumference. On the lower surface of the arm base 1106, two pairs of contacts 1118 are disposed at positions facing the conductors 1117 disposed on the upper surface of the lower end member 1105.

  FIG. 3 is a diagram showing a circuit including the above-described switch mechanism and sound generator 1116. As shown in FIG. 3, one of the contacts 1118 is connected to, for example, a positive electrode of a battery disposed in the arm base 1106. The negative electrode of the battery is connected to one of a pair of terminals of the sound generator 1116. The other terminal of the sound generator 1116 is connected to the other end of the contact 1118. In addition, a switch is provided for the user to turn on / off the sound generation when sound generation by the sound generator 1116 is unnecessary.

  When the arm base 1106 rotates around the vertical axis on the lower end member 1105 with the ON / OFF switch turned ON, one of the conductors 1117 connects between the contacts 1118 every time it rotates 10 degrees. The circuit shown in FIG. 3 is energized. As a result, power is supplied to the sound generator 1116 to generate sound.

  In addition, the structure of the imaging device holding fixture 11 mentioned above can be arranged as follows.

  That is, the horizontal portions of the front arm 1107 and the front angle 1108 constitute an arm that is a rod-like body extending in the horizontal direction. Further, the base 1101, the lower holding member 1102, the upper holding member 1103, and the lower end member 1105 constitute a holding member that holds the arm so as to be rotatable around a vertical axis within a range of 360 degrees.

  In addition, the vertical portion of the front angle 1108 constitutes an extending member that extends downward from the arm at one end of the arm or at any position between the one end and the portion held by the holding member. .

  The above is the description of the structure of the imaging device holding instrument 11.

  Subsequently, the imaging device 12 will be described. The imaging device 12 is a general PDA with a built-in camera as hardware, such as a smartphone having a call function, a touch pad without a call function (a PDA having a touch panel and no phone function), and the like.

  The imaging device 12 has a built-in gyro sensor or acceleration sensor (hereinafter referred to as “sensor built-in type”) that is a sensor for measuring the rotation angle of the own device, and a device that does not incorporate these sensors (hereinafter “ Called "non-sensor built-in type").

  In order for the sensor-equipped imaging device 12 to perform the processing described below, it is only necessary that the movement angle around the vertical axis when the imaging direction of the camera of the imaging device 12 is the horizontal direction can be measured. Therefore, if it is a gyro sensor, at least one sensor (one or more gyro sensors) that measures angular acceleration around the axis in the vertical direction, and if it is an acceleration sensor, each acceleration in two different directions on the horizontal plane is measured. It is only necessary to include at least two sensors (acceleration sensors having two or more axes) for measurement.

  The imaging device 12 performs processing according to an application program (hereinafter referred to as “app”) downloaded from a predetermined program distribution site via the Internet and installed in the imaging device 12, for example, as shown in FIG. It functions as a device including a functional component. The function of each functional component of the imaging device 12 is as follows.

  First detection means 121: Each time the imaging device 12 moves 10 degrees around the vertical axis, the movement is detected, and a detection signal indicating the detection is generated. If the imaging device 12 is a sensor built-in type, the detection is performed based on a signal output from the sensor. If the imaging device 12 is a sensor-incorporated type, the detection is performed based on a sound signal emitted from the sound generator 1116 of the imaging device holding instrument 11 and picked up by a microphone included in the imaging device 12.

Instructing unit 122: Using the generation of the detection signal by the first detecting unit 121 as a trigger, an instruction signal indicating an imaging instruction is generated.
Imaging means 123: Takes an image with the generation of an instruction signal by the instruction means 122 as a trigger, and generates image data indicating an image obtained by the imaging.
Storage means 124: Stores the image data generated by the imaging means 123.
Second detection means 125: When the imaging apparatus 12 moves 360 degrees around the vertical axis from the reference position, the movement is detected, and a detection signal indicating the detection is generated.

  Transmission unit 126: A plurality of image data (multi-view image data) stored in the storage unit 124 is wirelessly transmitted to a predetermined terminal device (for example, a PC) disposed in a store where the imaging system 1 is disposed, for example. Send via LAN. Note that the terminal device to which the multi-view image data is transmitted and the data storage destination are, for example, identification data (for example, an access point ID and password in a wireless LAN, and a data transmission destination in the wireless LAN) written in the application. The IP address of the terminal device and the folder name of the storage destination).

  The above is the description of the configuration of the imaging device 12.

  An operation performed by the user of the imaging system 1 and an operation performed by the imaging system 1 when the imaging system 1 captures a multi-view image of the subject 9 will be described below. In the following description, it is assumed that the user who operates the imaging device holding instrument 11 is a hairdresser and the subject 9 is the customer.

  First, the beautician turns on the laser pointer 1115 and positions the imaging device holding tool 11 so that the laser beam is irradiated near the center of the head of the customer who is seated with the hair set completed. Moving.

  Subsequently, the beautician receives, for example, the imaging device 12 possessed by the customer from the customer, activates the application, and then sets it in the holder 1110. In this state, the imaging device 12 continuously captures images of the customer with the background plate 1112 as a background by the camera, and sequentially displays images obtained by the imaging on the display of the imaging device 12. The beautician adjusts the vertical position and size of the customer's face in the image by operating the fastening member 1104 and the fastening member 1109 as necessary while viewing the image displayed on the display of the imaging device 12.

  Subsequently, the beautician adjusts the position of the weight 1113 in the horizontal direction as necessary while observing the position of the bubbles in the leveler 1114, and takes the arms and the arm base 1106 horizontally.

  When the imaging device 12 is a sensor non-built-in type, the beautician turns on the sound generator 1116.

  Subsequently, the beautician touches a button for instructing start of multi-view image shooting on the operation screen of the application. In response to the touch operation, the imaging device 12 starts a series of processes for generating multi-view image data.

  FIG. 5 is a flowchart showing processing in the sensor built-in type imaging device 12.

  First, the imaging device 12 specifies the position of the imaging device 12 when the beautician touches the button for instructing the start of multi-view image shooting as a reference position, and initializes the threshold value V of the movement angle to “10 degrees”. After that, the rotation angle measurement by the sensor is started (step S101).

  For example, the beautician applies force so as to push out the vicinity of the corner portion of the front angle 1108 in the horizontal direction from right to left. According to the force, the arm of the imaging device holding tool 11 rotates clockwise as viewed from above. As the arm rotates, the imaging device 12 moves around the customer's head while maintaining a state where the customer's head is captured in the imaging direction of the camera.

  During the above movement, the imaging device 12 determines whether or not the rotation angle measurement result by the sensor has reached the threshold value V at a sufficiently short interval (step S102).

  If it is determined in step S102 that the rotation angle has not reached the threshold value V (step S102; No), the imaging device 12 returns the process to step S102. That is, the imaging device 12 stands by until the rotation angle reaches the threshold value V.

  If it is determined in step S102 that the rotation angle has reached the threshold value V (step S102; Yes), the imaging device 12 performs imaging and generates image data indicating the captured image (step S103).

  When the process of step S103 is completed, the imaging device 12 determines whether or not the threshold value V is 360 degrees (step S104).

  If it is determined in step S104 that the threshold V is not 360 degrees (step S104; No), the imaging device 12 adds 10 degrees to the threshold V (step S105), and then returns the process to step S102. Therefore, the imaging process in step S103 is repeated every time the imaging apparatus 12 moves 10 degrees until the rotation angle reaches 360 degrees.

  If it is determined in step S104 that the threshold value V is 360 degrees (step S104; yes), the imaging device 12 has obtained a total of 36 pieces of image data (multi-view image data) generated in step S103 so far. The data is transmitted to a predetermined PC in the store via the wireless LAN (step S106).

  The above is the process associated with the generation of multi-view image data in the sensor built-in type imaging device 12.

  Next, processing associated with the generation of multi-view image data in the non-sensor built-in imaging device 12 will be described with reference to the flowchart of FIG.

  First, the imaging device 12 initializes the value C of the counter to “1”, and then starts picking up sound with a microphone (step S201).

  For example, the beautician applies force so as to push out the vicinity of the corner portion of the front angle 1108 in the horizontal direction from right to left. According to the force, the arm of the imaging device holding tool 11 rotates clockwise as viewed from above. As the arm rotates, the imaging device 12 moves around the customer's head while maintaining a state where the customer's head is captured in the imaging direction of the camera.

  During the above movement, the imaging device 12 generates a waveform of a sound picked up by the microphone at a sufficiently short interval, and a waveform of a sound (reference waveform) emitted from the sound generator 1116 indicated by data included in the application in advance. ) And determine whether or not their similarity is greater than or equal to a predetermined threshold (step S202).

  When it is determined in step S202 that the waveform of the picked-up sound is not similar to the reference waveform (step S202; No), the imaging device 12 returns the process to step S202. That is, the imaging device 12 stands by until a sound is emitted from the sound generator 1116.

  If it is determined in step S202 that the waveform of the picked-up sound is similar to the reference waveform (step S202; Yes), the imaging device 12 performs imaging and obtains image data indicating the captured image. Generate (step S203).

  When the process of step S203 is completed, the imaging device 12 determines whether or not the counter C is 36 (step S204).

  If it is determined in step S204 that the counter C is not 36 (step S204; No), the imaging device 12 adds 1 to the counter C (step S205), and then returns the process to step S202. The sound generator 1116 emits a sound according to the reference waveform every time the imaging device 12 moves 10 degrees. Therefore, as in the case where the imaging device 12 is a sensor built-in type, the imaging process in step S203 is repeated every time the imaging device 12 moves 10 degrees until the rotation angle reaches 360 degrees.

  When it is determined in step S204 that the counter C is 36 (step S204; Yes), the imaging device 12 stores the total 36 pieces of image data (multi-view image data) generated in step S203 so far in the store. To the predetermined PC or the like via the wireless LAN (step S206).

  The above is description of the process performed in the imaging device 12 with the production | generation of multiview image data.

  The total 36 images indicated by the multi-view image data generated as described above are operated according to the application, for example, when the customer operates the imaging device 12 (for example, when the imaging device 12 includes a touch panel, the screen is horizontally oriented). When a paying operation (flick operation) is performed, the images are sequentially displayed on the display of the imaging device 12 in the order of shooting (or reverse order). As a result, the customer can see his / her head from any direction within the range of 360 degrees.

  In addition, the beauty salon can browse and manage the multi-view image data of the customer on, for example, a PC in the store.

(Second embodiment)
Hereinafter, an imaging system 2 which is another specific example of the present invention will be described as a second embodiment. The imaging system 2 is a multi-view image imaging system installed in, for example, a game facility. Since the imaging system 2 is common to the imaging system 1 in many respects, the following description focuses on the differences between the imaging system 2 and the imaging system 1. Moreover, the same code | symbol is used about the thing similar to the thing with which the imaging system 1 is provided among the components with which the imaging system 2 is provided.

  FIG. 7 is a diagram schematically illustrating the appearance of the imaging system 2. First, the imaging system 2 includes an imaging device holding facility 21 and an imaging device 12.

  The imaging device holding equipment 21 includes a wall 211 whose inner side surface is cylindrical with the vertical axis as an axis, a rail 212 that draws a circle disposed on the inner side surface near the upper end of the wall 211, and a rail extending from the rail 212. A stretching member 213 that moves upward, and a holder 1110 that is fixed to the stretching member 213 and holds the imaging device 12 so as to be capable of imaging toward the above-described vertical axis.

  A wheel (not shown) that engages with the rail 212 and rotates on the rail 212 and a motor (not shown) that drives and rotates the wheel are attached to the end of the extending member 213 that is connected to the rail 212. Yes. The motor that drives the wheels of the extending member 213 receives power from a power source (not shown) such as a commercial power source via the rail 212, for example.

  On the rail 212, two pairs of terminals respectively connected to the positive electrode and the negative electrode of the power supply are arranged around the cylindrical central axis of the wall 211 at intervals of 10 degrees. When the extending member 213 reaches the position of each conductor, the terminals are connected to the terminals of the circuit including the sound generator 1116, and the sound generator 1116 is energized, so that sound is generated.

  On the inner surface of the wall 211, for example, a liquid crystal display (not shown) shaped along the curve of the wall 211 is arranged without a gap. For example, a user (by operating a controller attached under the holder 1110) ( The background image selected by the subject 9) is displayed in a panoramic view.

  The user attaches his / her imaging device 12 to the holder 1110 and performs an operation to start capturing a multi-view image on the application screen. Subsequently, the user operates the controller to select the background image theme, and then instructs the start of multi-view image shooting. According to the start instruction, the extending member 213 moves on the rail 212 by driving the motor of the imaging system 2 and driving the wheels. At that time, the sound generator 1116 produces a sound every time it moves 10 degrees.

  The imaging device 12 performs multi-view image imaging processing of the subject 9 by the same operation as described above with respect to the imaging system 1. At that time, a background image selected by the user is displayed on the wall 211. As a result, the background of the image indicated by the generated multi-view image data is as desired by the user.

(Modification)
The embodiments described above can be variously modified within the scope of the technical idea of the present invention. Examples of these modifications are shown below.

  First, the shape, numerical value, position, and the like of each component of the imaging system 1 and the imaging system 2 may be changed in any way as long as the function can be achieved. In the above description, the material of each component of the imaging system 1 and the imaging system 2 is not particularly mentioned, but any material may be employed as long as the material can fulfill its function. .

  For example, in the imaging system 1, the base 1101 is a disk-shaped member. However, as long as it can support other components of the imaging system 1 such as a tripod type member, A component member may be employed.

  In the imaging system 1, the background plate 1112 is curved, but a plate-like member that is not curved may be employed as the background plate 1112.

  Further, in the imaging system 1, the level device 1114 is disposed on the arm base 1106. However, if the level of the arm can be confirmed, other components such as a horizontal portion of the front arm 1107 and the rear angle 1111 can be used. A level 1114 may be arranged at the position.

  In the imaging system 1, the height adjustment mechanism (vertical position adjustment mechanism) of the holder 1110 is constituted by an upper holding member 1103 inserted into the lower holding member 1102 and a tightening member 1104 arranged at a connecting portion thereof. Although configured, for example, a similar height adjustment mechanism may be provided in the front vertical portion of the upper holding member 1103 and the vertical portion of the front angle 1108. In addition, the adjustment mechanism is not limited to a configuration in which the other pipe is inserted into one pipe and the other pipe is tightened by a tightening member. It may be adopted.

  In the imaging system 1, the distance adjustment mechanism (horizontal position adjustment mechanism) between the holder 1110 and the subject 9 includes a front angle 1108 inserted into the front arm 1107 and a fastening member disposed at a connecting portion thereof. 1109. However, for example, an adjustment mechanism having another configuration such as an adjustment mechanism that adjusts the position of the holder 1110 in the horizontal direction by expanding and contracting the front arm 1107 with respect to the arm base 1106 may be employed. .

  In the imaging system 1, the weight 1113 is arranged on the front arm 1107. However, when a larger load is applied to the holder 1110 side of the arm than the background plate 1112 side, the weight 1113 is set to the rear angle. It is arranged in the horizontal portion of 1111.

  Further, in the imaging system 1 and the imaging system 2, the imaging is performed every 10 degrees of movement, but the angle can be arbitrarily changed. For example, when a configuration in which imaging is performed every 5 degrees of movement is adopted, the image appears to transition more smoothly in the viewing of the multi-view image compared to the case of 10 degrees.

  Further, the mechanism for generating sound by the sound generator 1116 every time the imaging device 12 moves by a predetermined angle is not limited to the mechanism employed in the imaging system 1 and the imaging system 2 described above. For example, other mechanisms may be employed such as a mechanism in which the sound generator 1116 is provided with a gyro sensor or an acceleration sensor, and the sound generator 1116 generates a sound according to a signal indicating the rotational angle of movement output from those sensors. .

  Further, without providing the sound generator 1116, a mechanism in which sound generators arranged at equiangular intervals on the circumference are struck and vibrated to emit sound as the arm base 1106 rotates and the extending member 213 moves, etc. Other pronunciation mechanisms may be employed.

  In the imaging system 1, the arm is manually rotated by the user. However, a configuration in which the arm is rotated by a driving mechanism using a motor, a spring, a spring, or the like may be employed.

  In addition, all the components included in the imaging system 1 or the imaging system 2 are not necessarily required. For example, the weight 1113 and the level 1114 are not necessary if the arm is not obstructed so much even if the arm is slightly inclined. In addition, since the position adjustment of the imaging device holding device 11 can be performed by the amount of scale, the laser pointer 1115 is not essential. Further, if only the sensor built-in type imaging device 12 is used, the sound generator 1116 is also unnecessary.

  Further, the mechanism for holding the arm so as to be rotatable about the vertical axis is not limited to that employed in the imaging system 1.

  Further, in the imaging system 1, a configuration is adopted in which the arm is held by a holding member placed on the floor surface. For example, the arm is rotated by a holding member attached so as to extend downward from the ceiling. A configuration that is held movably may be employed.

  In the imaging system 1, the multi-view image data generated by the imaging device 12 is transmitted to a predetermined information processing device via a wireless LAN. For example, the multi-view image data is transmitted to a predetermined server device on the Internet via a mobile telephone network. For example, the transmission route and the transmission destination can be arbitrarily changed. Further, transmission of multi-view image data from the imaging device 12 to an external information processing device is not essential.

  In the imaging system 2, the rail 212 is arranged near the upper end of the wall 211, but the arrangement position of the rail 212 is not limited to the vicinity of the upper end of the wall 211, and is arranged at another position, for example, on the floor surface. May be. When the rail 212 is arranged at a position lower than the head position of the subject 9, the extending member 213 extends upward from the rail 212.

  In addition, an imaging apparatus holding fixture having a configuration in which a wall 211 in the imaging system 2 is provided instead of the background plate 1112 in the imaging system 1 and the arm is rotatably held by a holding means from the ceiling may be employed.

  In addition, the flow of processing performed by the imaging device 12 when multi-view image data is generated is not limited to that described above, and any processing flow that yields an equivalent or similar result may be employed. For example, in the imaging system 1, after the generation of image data indicating 36 images is completed, a flow of transmitting the image data to an external information processing apparatus at the same time is employed. Accordingly, a flow may be employed in which the generated image data is sequentially transmitted to the information processing device each time the image data is generated.

  In the imaging system 2, the background image is displayed on the wall 211 by the liquid crystal display. For example, the wall 211 is a monochrome wall and a projector that projects the background image on the wall 211 is provided. The background image may be displayed according to the configuration. Further, a display device such as a liquid crystal display may be arranged on the background plate 1112 in the imaging system 1 so that the background image can be selected.

  In addition, the imaging device 12 of the imaging system 1 or the imaging system 2 cuts out only the portion of the subject 9 from the image obtained by imaging, and overlays the cut-out image of the subject 9 on the previously stored background image The structure which performs may be employ | adopted. In that case, it is desirable that the background plate 1112 or the wall 211 be a single color that allows easy image cutting.

  The imaging device holding fixture, the imaging device, and the imaging system according to the present invention can generate multi-view images with a simple and inexpensive configuration, and thus are used in many fields such as a service industry such as a hairdressing and beauty industry and a medical treatment. It is expected. Therefore, it is manufactured and sold in large quantities and can be used in a service industry such as a so-called manufacturing industry or a retail industry.
