The output of the display control unit 114 is connected to the display unit 112, and the connection unit 115 and the imaging unit 212 of the electronic camera 200 are connected to each other. The control unit 118 detects the states of the operation unit 113 and the detection unit 117, and reproduces sound on the speaker 111 and displays an image on the display unit 112 in accordance with a user instruction performed via the operation unit 113. In addition, the control unit 118 performs imaging by the imaging unit 212 through the connection unit 115 in accordance with a user instruction performed through the operation unit 113. Note that the control unit 118 may acquire the image information generated by the imaging unit 212 via the connection unit 115 and display it on the display unit 112 via the display control unit 114. By displaying image information of an image (so-called through image) generated during composition confirmation on the display unit 112, the display unit 112 of the HMD 100 can be used as a viewfinder of the electronic camera 200.

Next, connection of the electronic camera 200 to the HMD 100 will be described. As shown in FIG. 3, the electronic camera 200 is connected to the connecting portion 111 a of the HMD 100 via the attachment 300.

As shown in FIG. 4A, the electronic camera 200 includes a tripod seat 220 on the bottom surface.
The attachment 300 includes a screw hole 320 corresponding to the tripod seat 220 as shown in FIGS. 4B and 4C. Further, the attachment 300 includes detection magnets M1 to M6 on the lower surface, and includes two convex portions 321 and 322. The detection magnets M1 to M6 are small magnets arranged continuously in alternate magnetization directions, and are arranged around the screw hole 320 as shown in FIG. 4C. Further, as shown in FIG. 4D, the convex portions 321 and 322 are each composed of a spring and a spherical member. Furthermore, as shown in FIGS. 4B and 4E, the attachment 300 includes a guide 323 parallel to the exterior of the attachment 300 on the front side.

  As shown in FIGS. 4F and 4G, the connecting portion 111 a includes a screw hole 150 corresponding to the screw hole 320 of the tripod seat 220 and the attachment 300. Further, the connecting portion 111 a includes two concave portions 151 and 152 corresponding to the two convex portions 321 and 322 of the attachment 300, respectively. Further, the connecting portion 111a includes Hall elements 153 corresponding to the detection magnets M1 to M6 of the attachment 300.

FIG. 5A is a front view when the HMD 100, the electronic camera 200, and the attachment 300 are connected. FIG. 5B is a view of FIG. 5A viewed from the direction of the arrow h.
The HMD 100, the electronic camera 200, and the attachment 300 configured as described above are connected by screws 401 and 402 as shown in FIG. 5A.
First, the electronic camera 200 and the attachment 300 are fixed with the screw 401. The screw 401 passes through the screw hole 320 of the attachment 300 and is fixed to the tripod seat 220 of the electronic camera 200. The electronic camera 200 and the attachment 300 are fixed in a non-rotatable state by screws 401.

At this time, the electronic camera 200 is fixed to the attachment 300 so as to contact the guide 323 of the attachment 300 as shown in FIG. 5B. As a result, the exterior on the front side of the attachment 300 and the optical axis in the electronic camera 200 are fixed vertically.
The configuration of the guide 323 is not limited to this example. Any design may be used as long as the electronic camera 200 can be attached to the HMD 100 in a predetermined posture.

Next, the attachment 300 to which the electronic camera 200 is fixed and the connecting portion 111 a of the HMD 100 are connected by screws 402. The screw 402 passes through the screw hole 150 of the connecting portion 111a and is connected to the screw 401 described above.
At this time, the convex portions 321 and 322 of the attachment 300 are fitted into the concave portions 151 and 152 of the connecting portion 111a of the HMD 100, respectively. As a result, the attachment 300 to which the electronic camera 200 is fixed and the connecting portion 111a are connected in parallel. In addition, since the exterior on the front side of the attachment 300 and the optical axis of the electronic camera 200 are fixed vertically, the connecting portion 111a and the optical axis of the electronic camera 200 are arranged vertically.

  The screw 402 connects the attachment 300 to which the electronic camera 200 is fixed and the connecting portion 111a in a rotatable state. Since the protrusions 321 and 322 of the attachment 300 are made of a spring and a spherical member as described above, the attachment 300 is rotated with respect to the connecting portion 111a in a state where the attachment 300 is pressed against the connecting portion 111a. It is possible. FIG. 6A shows a state in which the convex portions 321 and 322 of the attachment 300 are fitted in the concave portions 151 and 152 of the connecting portion 111a (hereinafter referred to as “reference state”), and FIG. 6B fixes the electronic camera 200. The state which rotated the attached attachment 300 with respect to the connection part 111a is shown. As shown in FIGS. 6A and 6B, the attachment 300 to which the electronic camera 200 is fixed can rotate in the direction of arrow i about the rotation axis s. The rotation axis s corresponds to a straight line connecting the tripod base 220 of the electronic camera 200, the screw hole 320 of the attachment 300, and the screw hole 150 of the connecting portion 111a.

In the connection state shown in FIGS. 5 and 6, the HMD 100 and the electronic camera 200 are electrically connected via the attachment 300. Various information such as control signals, image information, and audio information are supplied to each other.
5 and 6, the display unit 112 and the electronic camera 200 are independently supported on the basis of the coupling unit 111a (see FIG. 1). Therefore, in the connected state, the stability of the electronic camera 200 is high, and the vibration of the display unit 112 is less likely to affect the electronic camera 200, so that blurring during imaging by the electronic camera 200 can be suppressed.

Next, the operation of the control unit 118 when the HMD 100 described above and the electronic camera 200 are connected to perform imaging will be described. The user performs an imaging instruction by the imaging unit 212 by operating the operation unit 113 of the HMD 100.
When imaging is performed by connecting the HMD 100 and the electronic camera 200, a subject image is captured using the display unit 112 as a viewfinder as described above. At this time, an appropriate photographing state is that the image that the user observes on the display unit 112 of the HMD 100 and the image generated by the electronic camera 200 substantially match. In order for the image observed by the user on the display unit 112 and the image generated by the electronic camera 200 to substantially match, the optical axis of the electronic camera 200 and the display direction of the display unit 112 are preferably parallel. . If the optical axis of the electronic camera 200 and the display direction of the display unit 112 are not parallel, an image observed by the user with the display unit 112 and an image generated by the electronic camera 200 are shifted, and the shooting feeling is reduced. It is hard to grasp.

Therefore, the control unit 118 obtains a difference between the optical axis of the electronic camera 200 and the display direction of the display unit 112, and detects whether or not the photographing state is appropriate. Note that the control unit 118 performs the following processing assuming that the position and orientation of the display unit 112 are correctly adjusted and the display direction of the display unit 112 is parallel to the optical axis of the user's eye.
The detection unit 117 detects the connection state between the HMD 100 and the attachment 300. FIG. 7 shows a view of the HMD 100 in the reference state as viewed from above. In the reference state, the exterior of the attachment 300 should be parallel to the connecting portion 111a. However, when the attachment 300 is not correctly connected to the reference state, the exterior of the attachment 300 and the connecting portion 111a are not parallel.

  When the attachment 300 rotates with respect to the connecting portion 111a, the detection magnets M1 to M6 sequentially pass through the vicinity of the hall element 153. The detection unit 117 detects the rotation angle based on the resistance value of the Hall element 153. This rotation angle indicates a rotational deviation of the attachment 300 with respect to the connecting portion 111a. Then, the detection unit 117 outputs the detected rotation angle to the control unit 118.

  The control unit 118 obtains a difference between the optical axis in the electronic camera 200 and the display direction of the display unit 112 based on the rotation angle acquired from the detection unit 117. The rotation angle detected by the detection unit 117 is an angle formed between the exterior of the front surface of the attachment 300 and the connection unit 111a. In FIG. 7, the exterior of the front surface of the attachment 300 and the optical axis j in the electronic camera 200 are always perpendicular, and the connecting portion 111a is parallel to the straight line k connecting the left and right speakers 111, and therefore based on the rotation angle described above. Thus, the angle formed by the optical axis j and the straight line k connecting the left and right speakers 111 in the electronic camera 200 can be obtained. Further, the straight line k connecting the left and right speakers 111 and the optical axis of the user's eyes are perpendicular, and the optical axis of the user's eyes and the display direction p of the display unit 112 are parallel, so the left and right speakers 111 are connected. The straight line k and the display direction p of the display unit 112 are perpendicular to each other. Therefore, the angle formed by the optical axis j in the electronic camera 200 and the display direction p of the display unit 112 can be obtained based on the angle formed by the optical axis j in the electronic camera 200 and the straight line k connecting the left and right speakers 111. . This finally obtained angle is the difference between the optical axis in the electronic camera 200 and the display direction of the display unit 112, and based on this difference, the control unit 118 detects whether or not the photographing state is appropriate. can do.

  When it is determined that the shooting state is not appropriate based on the detection result, the control unit 118 displays the detection result of the detection unit 117 on the display unit 112 via the display control unit 114. FIG. 8A shows a display example of the detection result. As shown in FIG. 8A, the control unit 118 displays a message m1 indicating the difference between the optical axis of the electronic camera 200 and the display direction of the display unit 112 on the display unit 112, so that the shooting state is not optimal for the user. , And prompts the user to adjust the attachment 300 to which the electronic camera 200 is fixed. The HMD 100 includes a mechanism capable of automatically adjusting the attitude of the electronic camera 200, and automatically adjusts the attitude of the electronic camera 200 based on the difference between the optical axis of the electronic camera 200 and the display direction of the display unit 112. It is also good.

  Note that the display unit 112 can adjust the detailed position, inclination, and the like, as described with reference to FIG. Therefore, even if the electronic camera 200 is correctly connected to the HMD 100 via the attachment 300, if the display unit 112 is not adjusted to an appropriate position and inclination, the optical axis in the electronic camera 200 and the display of the display unit 112 are displayed. The direction is not parallel. In such a case, a deviation occurs between the image that the user observes on the display unit 112 of the HMD 100 and the image generated by the electronic camera 200. Therefore, the control unit 118 may obtain the difference between the optical axis of the electronic camera 200 and the display direction of the display unit 112 in consideration of the adjustment state of the display unit 112.

The detection unit 117 includes an adjustment angle θ1 at a connection portion m (see FIG. 7) between the left-ear speaker 111 and the support arm 112a, and an adjustment angle at a connection portion n (see FIG. 7) between the support arm 112a and the display unit 112. θ2 is detected and output to the control unit 118.
The control unit 118 obtains a difference between the optical axis in the electronic camera 200 and the display direction of the display unit 112 based on the detection result acquired from the detection unit 117. The control unit 118 obtains the angle formed by the optical axis j in the electronic camera 200 and the display direction p of the display unit 112 based on the angle formed by the optical axis j in the electronic camera 200 and the straight line k connecting the left and right speakers 111. At this time, the adjustment angle θ1 at the connection portion m and the adjustment angle θ2 at the connection portion n are taken into consideration. As a result, a more accurate difference between the optical axis in the electronic camera 200 and the display direction of the display unit 112 can be obtained. Therefore, even when at least one of the connection of the electronic camera 200 to the HMD 100 and the adjustment of the display unit 112 is not correctly performed, it is possible to accurately grasp whether or not the photographing state is appropriate.

  In addition, when the user intentionally rotates the attachment 300 to which the electronic camera 200 is fixed, the detection result by the detection unit 117 is displayed on the display unit 112 as a numerical value indicating the attitude of the electronic camera 200. Also good. FIG. 8B shows a display example. As shown in FIG. 8B, the control unit 118 can present a numerical value indicating the attitude of the electronic camera 200 to the user by displaying a message m2 indicating the numerical value indicating the attitude of the electronic camera 200 on the display unit 112. . When the HMD 100 is equipped with a GPS, the GPS detection result may be displayed in addition to the message m2 indicating the numerical value indicating the attitude of the electronic camera 200.

  Note that an imaging device such as an electronic camera may be connectable to a place other than that described in this embodiment. For example, as illustrated in FIG. 9, the imaging device may be fixed in the vicinity of the right ear speaker 111 of the HMD 100. In such a configuration, the imaging device may be configured to be rotatable in the direction of the arrow q. As shown in FIG. 9, when the imaging device is arranged on the user's temporal region, the weight balance with the display unit is excellent, and the rotation of the imaging device can be adjusted without changing the adjustment state of other parts. is there.

  Further, for example, as illustrated in FIG. 10, an imaging device may be connected to a part of the support arm 112 a. In such a configuration, the imaging device may be configured to be rotatable in the direction of the arrow r. As illustrated in FIG. 10, when the imaging device is disposed on the side of the user's eye, the imaging device can be disposed at a position close to the user's line of sight. Furthermore, if the configuration is also rotatable in the direction of the arrow t, the posture of the imaging device can be changed in synchronization with the user's eyes.

Conversely, as described with reference to FIG. 1 of the present embodiment, when the imaging device is arranged at the user's head, the imaging device is arranged at the center of gravity of the user. In the retracted state, a compact storage state can be realized.
9 and 10, the imaging device is preferably arranged so as not to hinder the movement of the support arm 111a of the display unit 112. Therefore, it is preferable to connect the imaging device to a position that does not interfere with a mechanism for retracting the display unit 112.

  As described above, according to the present embodiment, in the head-mounted display provided with the display unit that displays an image, the fixing unit that can attach the imaging device to a predetermined posture with respect to the head-mounted display. Is provided. Therefore, in a head-mounted display provided with a display unit for displaying an image, when the head-mounted display and the imaging device are connected and used, shooting can be performed in an appropriate shooting state.

  In addition, according to the present embodiment, the holding unit that holds the head-mounted display on the user's head is provided, and the display unit and the imaging device attached to the fixed unit are independently supported on the basis of the holding unit. Is done. Therefore, the stability is high and the vibration of the display unit hardly affects the imaging apparatus, so that blurring during imaging by the imaging apparatus can be suppressed. In particular, in the configuration shown in FIG. 10, the imaging device is arranged in the vicinity of a straight line connecting the left and right speakers, so that it is less affected by the vibration of the display unit.

Moreover, according to this embodiment, the fixing | fixed part can change the attitude | position of the imaging device on the basis of a head mounted display. Therefore, it is possible to finely adjust the posture of the imaging device, and to intentionally adjust the imaging device to a posture different from the predetermined posture, thereby performing photographing according to the user's desire.
Moreover, according to this embodiment, the detection part which detects the change amount of the attitude | position of an imaging device is further provided. Therefore, it is possible to grasp a change in the posture of the imaging device with respect to the head-mounted display.

Further, according to the present embodiment, the detection unit detects the change amount based on the difference between the optical axis in the imaging apparatus and the display direction of the display unit. Therefore, it is possible to more accurately grasp the change in the posture of the imaging device with respect to the head-mounted display.
Moreover, according to this embodiment, a display part displays the detection result by a detection part. Therefore, information for adjusting the posture of the imaging apparatus to an appropriate shooting state can be presented to the user.

  In the present embodiment, the example in which the electronic camera 200 is connected to the connecting portion 111a of the HMD 100 via the attachment 300 has been described. However, if the electronic camera 200 can be attached to the HMD 100 in a predetermined posture. The mechanism similar to the attachment 300 may be provided in advance in the connecting portion 111a of the HMD 100. Further, the electronic camera 200 may be configured to have a mechanism similar to that of the attachment 300 in advance.

Further, the attachment may be prepared for each camera or may be configured to be applicable to a plurality of cameras.
Moreover, in this embodiment, although the structure which electrically connects HMD100 and the electronic camera 200 via the attachment 300 was shown, if the electronic camera 200 can be attached to a predetermined attitude | position with respect to HMD100, The configuration may be such that the HMD 100 and the electronic camera 200 are electrically connected by wire or wireless such as a cable.

  In the present embodiment, the example in which the HMD 100, the electronic camera 200, and the attachment 300 are connected using the tripod base 220 of the electronic camera 200 as a reference is described. For example, the electronic camera 200 and the attachment 300 may be fixed with the tripod base 220 as a reference, and the attachment 300 and the HMD 100 may be connected to the tripod base 220 independently.

In the present embodiment, the state in which the optical axis in the electronic camera 200 and the display direction of the display unit 112 are parallel is set as the reference state, but this reference state is determined according to the convergence angle of the user's eyes, etc. You may adjust suitably.
In the present embodiment, an example in which the exterior 300 on the front side of the attachment 300 and the optical axis of the electronic camera 200 are vertically fixed by providing the guide 323 in the attachment 300 has been shown, but the depth of the tripod seat 220 is designed. For example, the guide 323 may not be provided, and the front-side exterior of the attachment 300 and the optical axis of the electronic camera 200 may be fixed vertically.

In the present embodiment, an example is shown in which each part is detected with reference to the straight line k connecting the left and right speakers 111, but other parts may be used as a reference. For example, the support arm 111a may be used as a reference.
Further, in the present embodiment, an example in which the HMD 100 and the electronic camera 200 are electrically connected via the attachment 300 and various kinds of information such as control signals, image information, and audio information are supplied to each other has been described. However, all of the control signal, image information, and audio information may not be supplied to each other via the attachment 300. For example, only the image information may be configured to be supplied from the electronic camera 200 to the HMD 100, the HMD 100 may be used as a viewfinder, and a user's imaging instruction may be received by the operation unit of the electronic camera 200. In addition, only the control information may be configured to be supplied from the HMD 100 to the electronic camera 200, and a user's imaging instruction may be received by the operation unit 113 of the HMD 100.
