Description

[Technical field]

[0001] The present invention relates to an information processing device, an imaging device, a control method, and a program. [Background technology]

[0002] There are conventionally wearable imaging devices such as wearable cameras. By wearing the imaging device around the neck, hands-free photography is possible. In addition, by providing the imaging device with wireless communication capabilities, the instructor can check the captured images even if he or she is in a different location from the wearer.

[0003] Wearable imaging devices are expected to have electric pan-tilt-zoom (PTZ) drive capabilities. If electric PTZ drive is possible, an instructor in a different location from the wearer can change the shooting direction and magnification to check the details of the subject.

[0004] The shooting direction of the wearable imaging device changes according to the movement of the wearer. An instructor in a different location from the wearer cannot grasp the change in the shooting direction because the shooting direction changes without issuing any instructions.

[0005] In order to solve the above-mentioned problems, a technique for detecting the movement of a wearer and changing the shooting direction has been disclosed. For example, Patent Document 1 discloses a technique for detecting the movement of a wearer in electronic binoculars and changing the shooting direction. [Prior art documents] [Patent documents]

[0007] However, in the technology of Patent Document 1, the wearer of the imaging device and the instructor are the same person. If the instructor is in a different location from the wearer, the change in the shooting direction caused by the wearer's movement cannot be communicated to the instructor.

[0008] Therefore, an object of the present invention is to provide a technique that enables an instructor to grasp a change in the shooting direction. [Means for solving the problem]

[0040] FIG. 2 is an external view of the imaging device according to the first embodiment.

[0041] The wearable imaging device 101 according to this embodiment is an imaging device that can be worn around the neck of a wearer, but is not limited to this. The imaging device 101 may be worn at any position on the wearer's body via a mounting mechanism that allows the imaging device 101 to be mounted on a part of the wearer's body.

[0042] The imaging device 101 includes a mounting unit 201, a main body unit 202, a wiring unit 203 that connects the mounting unit 201 and the main body unit 202, and a driving imaging unit 102 that acquires a captured image. The imaging device 101 acquires a captured image while the wearer wears the imaging device 101 around his neck. The acquired captured image is sent to the information processing device 113 by wireless communication and is displayed on the display unit 116.

[0043] The mounting portion 201 has a curved shape that enables the image capturing device 101 to be held around the neck of the wearer.

[0044] The main body unit 202 includes a power supply unit for driving the driving imaging unit 102, a network processing unit 104 for communicating with the information processing device 113, and the like.

[0045] The wiring section 203 includes wiring for transmitting power and signals between the mounting section 201 and the main body section 202 .

[0046] Fig. 3 is a diagram showing a display unit of an information processing device that displays an imaging direction display according to the first embodiment. Fig. 3 shows a screen of the display unit 116 of the information processing device 113.

[0047] The display unit 116 displays a captured image 301 acquired by the driving imaging unit 102, a pan operation unit 302 for operating the pan direction of the driving imaging unit 102, a tilt operation unit 303 for operating the tilt direction, a zoom operation unit 304 for enlarging and reducing, a pan direction shooting direction display 305, a tilt direction shooting direction display 306, and a captured image 307 acquired by the driving imaging unit 102 when setting the initial position. Note that setting the initial position means setting the display position of the shooting direction display in the pan and tilt directions based on at least one of the position in an arbitrary coordinate system of the imaging device 101 and the reference imaging direction of the driving imaging unit 102.

[0048] The pan direction shooting direction display 305 displays a pan direction shooting range 308 currently being shot by the driving imaging unit 102, a pan direction shootable range 309, and a pan direction rotation range 310 by the wearer. Since the orientation of the wearer's body can rotate 360 ​​degrees in the pan direction, the pan direction rotation range 310 is displayed as a circle. Note that the pan direction shootable range 309 is not an essential display element, and may be displayed according to a setting by an instructor.

[0049] The tilt direction shooting direction display 306 indicates the tilt direction shooting range 311 currently being shot by the driving imaging unit 102, the tilt direction shootable range 312, and the tilt direction rotation range 313 by the wearer. Since the orientation of the wearer's body cannot be rotated 360 degrees in the tilt direction, the tilt direction rotation range 313 is displayed as a semicircle. Note that the tilt direction shootable range 312 is not an essential display element, and may be displayed according to the settings of the instructor.

[0050] Fig. 4 is a diagram for explaining a method for setting an initial position of an imaging direction display according to the first embodiment. Fig. 4 shows a screen of the display unit 116 of the information processing device 113 before the initial position is set.

[0051] Before setting the initial position of the shooting direction display, the display unit 116 does not display the captured image 307. After setting the initial position of the shooting direction display, the driving imaging unit 102 acquires the captured image 307, and the display unit 116 displays a thumbnail of the captured image 307. After that, the display unit 116 continues to display the captured image 307 regardless of changes in the shooting direction.

[0052] The pan direction imaging direction display 305 displays only the pan direction rotation range 310 by the wearer. After the initial position of the imaging direction display is set, the display unit 116 displays the pan direction imaging range 308 and the pan direction imageable range 309 as shown in FIG.

[0053] The imaging direction display 306 in the tilt direction displays only the tilt direction rotation range 313 by the wearer. After the initial position of the imaging direction display is set, the display unit 116 displays the tilt direction imaging range 311 and the tilt direction imaging possible range 312 as shown in FIG.

[0054] Here, the wearer may set the initial position of the imaging direction display, an instructor may set the initial position via the information processing device 113, or the initial position may be set automatically.

[0055] When the wearer sets the initial position of the imaging direction display, for example, a switch (input unit 1305) is provided on the mounting unit 201 and the main body unit 202, and the wearer sets the initial position by switching the switch. When the instructor sets the initial position of the imaging direction display, a switch (input unit 1313) is provided on the display unit 116 of the information processing device 113, and the instructor sets the initial position of the imaging direction display by switching the switch. When the initial position of the imaging direction display is automatically set, the system control unit 117 compares, for example, several frames of the captured image 301. Then, when the system control unit 117 determines that there is no change in the image features by comparing several frames of the captured image 301, it may set the current imaging direction as the initial position of the imaging direction display. When there is a change in the features of the captured image 301, it is assumed that the wearer's body orientation has been changed or the driving imaging unit 102 has been driven. On the other hand, when there is no change in the features of the captured image 301, it is assumed that there is no change in the wearer's body orientation and no driving of the driving imaging unit 102 has been performed. Alternatively, the system control unit 117 may set the current shooting direction as the initial position of the shooting direction display based on a change in the output of the sensor 1304 (e.g., the rotation angle of the wearer) acquired via the network processing unit 114. For example, if there is no change in the output of the sensor 1304, it is assumed that the wearer's body orientation has not changed and the driving imaging unit 102 has not been driven. On the other hand, if there is a change in the output of the sensor 1304, it is assumed that the wearer's body orientation has changed or the driving imaging unit 102 has been driven.

[0056] 5 is a diagram for explaining a method for displaying the shooting direction display according to the first embodiment. Hereinafter, the method for displaying the shooting direction display will be explained using the pan direction as an example.

[0057] 5(A) shows the pan direction shooting direction display 305 when the orientation of the wearer rotates. After the initial position of the shooting direction display is set, the wearer rotates to the left. In this case, the pan direction shooting range 308 and the pan direction shootable range 309 rotate by the same angle as the rotation angle of the wearer. The rotation angle of the wearer is calculated based on the detection result of the shooting direction detection unit 111. The rotation angle of the wearer is detected, for example, via a gyro sensor (sensor 1304) mounted on the imaging device 101.

[0058] 5B shows the pan direction shooting direction display 305 when the driving imaging unit 102 rotates in the pan direction. After the initial position of the shooting direction display is set, the driving imaging unit 102 rotates to the left, so only the pan direction shooting range 308 rotates. The rotation angle of the driving imaging unit 102 is determined by the pan operation of the instructor.

[0059] FIG. 6 is a diagram showing the display unit of the information processing device when performing a drive operation with the shooting direction display according to the first embodiment.

[0060] 6. Compared to FIG. 3, the display unit 116 of the information processing device 113 in FIG. 6 does not display the pan operation unit 302 and the tilt operation unit 303.

[0061] FIG. 7 is a diagram showing an operation method when performing a drive operation in the shooting direction display according to the first embodiment.

[0062] Fig. 7(A) shows the shooting direction display 305 in the pan direction before the shooting direction is changed. Fig. 7(B) shows the shooting direction display 305 in the pan direction after the shooting direction is changed. The instructor selects the current pan direction shooting range 308 with the operation unit 701 (shown by an arrow) and drags it to drive the driving imaging unit 102.

[0063] FIG. 8 is a diagram showing the display unit of the information processing device in a case where the shooting direction is displayed on the drive operation display according to the first embodiment.

[0064] Fig. 8 shows the display unit 116 of the information processing device 113 when the shooting direction is displayed on the drive operation display. Compared to Fig. 3, Fig. 8 does not have a pan direction shooting direction display 305 and a tilt direction shooting direction display 306. Furthermore, in Fig. 8, a pan direction shooting range 308 and a pan direction shootable range 309 exist on the pan operation unit 302. Similarly, a tilt direction shooting range 311 and a tilt direction shootable range 312 exist on the tilt operation unit 303.

[0065] The initial position of the shooting direction display is set based on the same method as in Fig. 4. The display method for setting the initial position of the shooting direction display is set based on the same method as in Fig. 5. In Fig. 5, the pan direction shooting range 308 and the pan direction shootable range 309 rotate, but in Fig. 8, the pan direction shooting range 308 and the pan direction shootable range 309 slide horizontally.

[0066] 9 is a flowchart for explaining a method for displaying the imaging direction display according to the first embodiment. The processing in FIG.

[0067] In S901, the system control unit 117 sets the initial position of the shooting direction display based on an input from an instructor. As described above, the wearer may set the initial position of the shooting direction display by pressing a switch provided on at least one of the mounting unit 201 and the main body unit 202 of the imaging device 101. Alternatively, the system control unit 117 may set the initial position of the shooting direction display based on a change over time in the characteristics (e.g., brightness value) of the captured image 301 in FIG. 3.

[0068] In S902, the system control unit 117 displays the pan direction shooting range 308 and the pan direction shootable range 309 on the screen of the display unit .

[0069] In S903, the system control unit 117 determines whether the wearer's body orientation has changed based on the detection result of the shooting direction detection unit 111 (for example, the rotation angle detected by a gyro sensor mounted on the imaging device 101). If the system control unit 117 determines that the wearer's body orientation has changed (Yes in S903), the process proceeds to S904. On the other hand, if the system control unit 117 determines that the wearer's body orientation has not changed (No in S903), the process proceeds to S905.

[0070] In S904, the system control unit 117 moves and displays the pan direction shooting range 308 and the pan direction shootable range 309 to positions according to the detection result of the shooting direction detection unit 111. As a result, even if the orientation of the wearer's body has changed, the instructor can grasp the imaging range and the imageable range of the imaging device 101 by checking the display positions of the pan direction shooting range 308 and the pan direction shootable range 309. Note that a change in the orientation of the wearer's body represents the same as a change in the orientation of the imaging device 101 as a whole.

[0071] In S905, the system control unit 117 determines whether the shooting direction of the driving imaging unit 102 has been changed by an operation by an instructor. If the system control unit 117 determines that the shooting direction of the driving imaging unit 102 has been changed by an operation by an instructor (Yes in S905), the process proceeds to S906. On the other hand, if the system control unit 117 determines that the shooting direction of the driving imaging unit 102 has not been changed by an operation by an instructor (No in S905), the process ends.

[0072] In S906, the system control unit 117 moves and displays the pan direction shooting range 308 to a position according to the drive amount of the driving imaging unit 102, and ends the process. This allows the instructor to grasp the imaging range and imageable range of the imaging device 101 by checking the display positions of the pan direction shooting range 308 and the pan direction captureable range 309, even if the shooting direction of the driving imaging unit 102 is changed.

[0073] As described above, according to the first embodiment, the display positions of the imaging range and the imaging possible range are changed in response to a change in the wearer's body orientation or a movement of the imaging unit, thereby enabling the instructor to easily grasp the imaging range and the imaging possible range.

[0074] Second embodiment In the second embodiment, a case where an imaging device has a wide-angle imaging unit will be described. In the second embodiment, differences from the first embodiment will be described.

[0075] 10 is a diagram showing the configuration of an imaging device having a wide-angle imaging section according to the second embodiment. Compared to the imaging device 101 in FIG.

[0076] The wide-angle imaging unit 1002 receives light on the light receiving surface of an image sensor 1004 via a lens 1003, amplifies the received light data with an amplifier 1005, and outputs an imaging signal.

[0077] FIG. 11 is an external view of an imaging device having a wide-angle imaging section according to the second embodiment.

[0078] Fig. 11 shows the appearance of an imaging device 1001 having a wide-angle imaging section 1002. Compared to the imaging device 101 in Fig. 2, the imaging device 1001 further includes a wide-angle imaging section 1002. The wide-angle imaging section 1002 captures a wide range of images while maintaining a fixed shooting direction. By using the wide-angle imaging section 1002 and the driving imaging section 102, the instructor can simultaneously capture a wide range of images and a magnified image of the periphery of the subject.

[0079] Fig. 12 is a diagram showing a display unit of an information processing device displaying an imaging direction display according to the second embodiment. Fig. 13 is an enlarged view of a part of the display unit of an information processing device displaying an imaging direction display according to the second embodiment.

[0080] Fig. 12 shows a screen of the display unit 116 of the information processing device 113. The pan direction shooting direction display 1201 and the tilt direction shooting direction display 1202 in Fig. 12 are different from the pan direction shooting direction display 305 and the tilt direction shooting direction display 306 in Fig. 3. The pan direction shooting direction display 1201 further includes a pan direction wide-angle shooting range 1203. Moreover, the tilt direction shooting direction display 1202 further includes a tilt direction wide-angle shooting range 1204. The initial setting and display method of the shooting direction display on the display unit 116 are similar to those in the first embodiment, and therefore detailed description will be omitted.

[0081] As described above, according to the second embodiment, the instructor can grasp the imaging range around the subject, the wide imaging range, and the imaging possible range on the screen of the display unit, thereby improving convenience for the instructor in monitoring work, etc.
