Description

[Technical field]

[0001] The present invention relates to a display device, and more particularly to a main body configuration of a display device. [Background technology]

[0002] There is a known display device (head mounted display: HMD) that is worn on the user's (observer's) head. By using an HMD, it is possible to easily view images on a large screen and in stereoscopic view. For this reason, HMDs are used as devices that enable the experience of artificial reality (virtual reality: VR) and mixed reality (mixed reality: MR).

[0003] An HMD for realizing MR has an imaging unit that captures real space, a display unit that displays the image of real space obtained by the imaging unit by superimposing a 3DCG image, and an eyepiece optical system that projects the image displayed by the display unit onto the user's eye. 3DCG is generated by, for example, a PC. PC is an abbreviation for Personal Computer, and 3DCG is an abbreviation for Three Dimensional Computer Graphics.

[0004] For example, an image is displayed on a small LCD panel, and the image is magnified by an eyepiece optical system and projected onto the user's eye. If two images with a parallax are projected onto the right and left eyes, respectively, the user can see the image in 3D. This parallax makes it possible to express 3DCG images (virtual objects) as if they actually exist.

[0005] An HMD may be provided with operation buttons so that the user can take actions on the object being observed or respond to inquiries from the HMD. In addition, the user can use the HMD not only in a hands-free state by wearing it on the head, but also by holding it in the hand and using it as a handheld display (HHD). For example, the user can wear the HMD on the head when verifying various tasks, and use the HMD as an HHD when only observing.

[0006] HMDs and HHDs are required to be small and lightweight to improve user comfort. As the main body (HMD or HHD) becomes smaller, the space for arranging operation buttons decreases. When multiple buttons are arranged closely together, the buttons become difficult to press, and erroneous operation is likely to occur. Patent Document 1 discloses a handle member for HHD that reduces erroneous button operation. Patent Document 2 discloses a technology in which a controller for switching images displayed on the HMD is connected to the HMD as an external device, and the display information is changed according to the angle of the head.

[0007] [Patent Document 1] JP 2021-114756 A [Patent Document 2] Patent Publication No. 2021-119431 Summary of the Invention [Problem to be solved by the invention]

[0008] However, in the conventional technology disclosed in Patent Document 1, the buttons are difficult to press and require time for operation. In the conventional technology disclosed in Patent Document 2, the operation is complicated and requires time for operation. Furthermore, in the conventional technology disclosed in Patent Document 2, the head needs to be kept at a certain angle, which may reduce usability.

[0009] The present invention aims to provide a display device that can easily switch settings while preventing operational errors. [Means for solving the problem]

[0010] The display device of the present invention comprises a first eyepiece optical system that projects an image onto one of the user's right eye or left eye, a second eyepiece optical system that projects an image onto the other of the user's right eye or left eye, a detection unit that detects the attitude of the display device, and a control unit that controls the projected image, and the control unit controls the projected image based on the detection result of the detection unit so as to project a first image in a first attitude in which the user looks into the first eyepiece optical system with the right eye and the second eyepiece optical system with the left eye, and to project a second image different from the first image in a second attitude in which the user looks into the second eyepiece optical system with the right eye and the first eyepiece optical system with the left eye. Effect of the Invention

[0011] According to the present invention, it is possible to easily switch settings while preventing operational errors. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] (Embodiment 1) Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. Figures 1(A) and 1(B) are front views showing a state in which a user H is using a display device 100 (main body) according to the first embodiment, and Figure 2 is a cross-sectional view showing the state.

[0014] The display device 100 includes an exterior 101. The exterior 101 is thin from front to back and has a horizontally long shape. Like a handheld display (HHD), a user H uses the display device 100 by holding the exterior 101 in his / her hand and looking into a rear opening 102. As shown in Figs. 1(A) and 1(B), the user H can also use the display device 100 by turning the entire display device 100 upside down. The position in Fig. 1(A) is described as a first position, and the position in Fig. 1(B) is described as a second position. Fig. 2 corresponds to the first position. The exterior 101 may be provided with an indicator that allows the user to determine whether the display device is in the first position or the second position from the outside. For example, a product or company logo may be provided on the front (front surface) of the exterior 101 so that the logo is in the upright position in the first position.

[0015] Each of the display panels 300L, 300R displays an image. For example, a Liquid Crystal Display (LCD) panel or an Organic Light Emitting Diode (OLED) panel is used as each of the display panels 300L, 300R. The display panels 300L, 300R are electrically connected to a control board 600 (control unit). Each of the prisms 400L, 400R is an ocular optical system that projects an image onto the eye of the user H. For example, each of the prisms 400L, 400R is a transparent optical system filled with an optical medium such as glass or plastic having a refractive index greater than 1. It is made of a light-emitting body and is made thin by folding the optical path using an eccentric reflecting curved surface.

[0016] In the first posture, the user H looks into the prism 400L with the left eye 200L and looks into the prism 400R with the right eye 200R. Therefore, the image displayed on the display panel 300L by the control board 600 passes through the prism 400L and is projected (guided) to the left eye 200L of the user H. Similarly, the image displayed on the display panel 300R by the control board 600 passes through the prism 400R and is projected (guided) to the right eye 200R of the user H. In the second posture, the user H looks into the prism 400L with the right eye 200R and looks into the prism 400R with the left eye 200L. Therefore, the image displayed on the display panel 300L passes through the prism 400L and is projected to the right eye 200R, and the image displayed on the display panel 300R passes through the prism 400R and is projected to the left eye 200L. As a display unit including a display panel and a prism, a retinal projection type display unit may be used.

[0017] In the first embodiment, the direction in which the prisms 400L, 400R are arranged is described as the X-axis direction, the direction parallel to the optical axis of the prisms 400L, 400R is described as the Z-axis direction, and the direction perpendicular to the X-axis and Z-axis directions is described as the Y-axis direction. The X-axis direction may be interpreted as the left-right direction of the display device 100. The Z-axis direction may be interpreted as the front-rear direction of the display device 100, or as the direction parallel to the optical axis of the eyes of the user H who is using the display device 100. The Y-axis direction may be interpreted as the up-down direction of the display device 100.

[0018] Cameras 500L and 500R are provided on the front surface of the display device 100 (the front surface of the exterior 101). Each of the cameras 500L and 500R is an imaging unit that captures an image of real space. A combination of the camera 500L and the camera 500R may be interpreted as a stereo camera. The control board 600 can display a real space image (image of real space) obtained by the camera 500L on the display panel 300L, and can display a real space image obtained by the camera 500R on the display panel 300R.

[0019] The control board 600 can also function as a detection unit that detects the position and orientation of the display device 100 based on real space images acquired by the cameras 500L and 500R. For example, the control board 600 detects features such as a marker or an edge of an object from the real space image, and detects the position and orientation of the display device 100 based on the features.

[0020] The method of detecting the position and orientation is not particularly limited, and the position and orientation may be detected using an imaging unit other than the cameras 500L and 500R. If a camera with a wide angle of view and a high shutter speed or a stereo camera with a long base line is used as such an imaging unit, the position and orientation can be detected with higher accuracy. A gyro sensor connected to the control board 600 may be provided in the display device 100, and the control board 600 may detect the orientation of the display device 100 based on an output signal of the gyro sensor. A proximity sensor connected to the control board 600 may be provided in the display device 100, and the control board 600 may detect the orientation of the display device 100 based on an output signal of the proximity sensor. If a plurality of methods are combined, the orientation of the display device 100 can be detected with higher accuracy.

[0021] A cable socket 103 is provided on a side surface of the display device 100 (a side surface of the exterior 101), and a cable 700 is connected to the cable socket 103. The control board 600 can communicate with an external device such as a personal computer or a controller via the cable 700. The control board 600 can generate an image in which a virtual object (e.g., a 3DCG image) is arranged (superimposed) in real space based on a real space image obtained by the cameras 500L and 500R, as an image to be projected (an image to be displayed on the display panels 300L and 300R).

[0022] If the cable 700 extends from the upper surface (top surface) or the lower surface (bottom surface) of the exterior 101 in the first position (FIGS. 1(A) and 2), the cable 700 may extend downward from the upper surface of the exterior 101 through the front surface in the first position or the second position (FIG. 1(B)). As a result, the cable 700 is reflected in the real space image obtained by the cameras 500L and 500R. In the first embodiment, the cable outlet 103 is disposed on the left side surface of the exterior 101 in the first position, and the cable outlet 103 is disposed on the right side surface of the exterior 101 in the second position. As a result, in both the first position and the second position, the cable 700 extends from the side surface of the exterior 101, and thus it is possible to suppress the cable 700 from being reflected in the real space image. Alternatively, the cable outlet 103 may be disposed on the right side of the exterior 101 in the first position, and the cable outlet 103 may be disposed on the left side of the exterior 101 in the second position.

[0023] The control board 600 can determine whether the attitude of the display device 100 is the first attitude or the second attitude by detecting the attitude of the display device 100 by the above method. Then, the control board 600 can control the image to be projected based on the detection result (determination result) of the attitude of the display device 100. For example, the control board 600 can set the image to be projected separately for the first attitude and the second attitude, and can control (switch) the image to be projected so that different images are projected in the first attitude and the second attitude. The image to be projected in the first attitude is referred to as the first image, and the image to be projected in the second attitude is referred to as the second image.

[0024] For example, one of the first image and the second image may be an image in which a virtual object is arranged in a real space. The other of the first image and the second image may be an image in which at least a part of the virtual object in the one image is changed. FIG. 3(A) shows an image projected in a first position, and FIG. 3(B) shows an image projected in a second position. In FIG. 3(A), CG images CG1 and CG2 of virtual objects are superimposed on a background image BG1, which is a real space image obtained by the camera 500L or the camera 500R. In FIG. 3(B), only the CG image CG2 is superimposed on the background image BG1, and the CG image CG1 is hidden. In this case, the CG image CG1 can be hidden in response to an inversion operation from the first position to the second position, or the CG image CG1 can be displayed in response to an inversion operation from the second position to the first position.

[0025] One of the first image and the second image may be an image in which a virtual object is arranged in a real space, and the other of the first image and the second image may be an image of only the virtual object. FIG. 4(A) shows an image projected in a first posture, and FIG. 4(B) shows an image projected in a second posture. In FIG. 4(A), a CG image CG3 of a virtual object is superimposed on a background image BG2, which is a real space image obtained by the camera 500L or the camera 500R. In FIG. 4(A), only the CG image CG3 is displayed, and the background image BG2 is hidden. In this case, the background image BG2 can be hidden in response to an inversion operation from the first posture to the second posture, or the background image BG2 can be displayed in response to an inversion operation from the second posture to the first posture.

[0026] The first image and the second image may have different magnifications, in which case the images can be enlarged or reduced in size in response to an inversion operation from one of the first and second positions to the other.

[0027] In this way, the display settings can be easily switched by simply changing the attitude of the display device 100 without performing any button operations.

[0028] 5(A) and 5(B) are diagrams showing a rear view and a cross section of the display device 100, respectively. 5(A) and 5(B) correspond to the first position. As shown in FIGS. 5(A) and 5(B), in the first embodiment, the optical axis (optical axis center) of the prism 400L and the optical axis (optical axis center) of the prism 400R are located at approximately the center of the display device 100 (approximately the center of the exterior 101) in the Y-axis direction. In FIG. 5(A), the position CR of the optical axis of the prisms 400L and 400R coincides with the position CH of the center of the exterior 101 in the Y-axis direction. In FIG. 5(B), the position CR of the optical axis of the prisms 400L and 400R is shifted by a shift amount t from the position CH of the center of the exterior 101 in the Y-axis direction. In order to provide a comfortable feeling of use in both the first position and the second position, it is preferable that the shift amount t is 15% or less of the size T (height) of the display device 100 (exterior 101) in the Y-axis direction. In addition, in the Y-axis direction, the position of the optical axis of the prism 400L preferably coincides with the position of the optical axis of the prism 400R, but they may be different.

[0029] The exterior 101 has a nose recess 104B which is a recess to which the nose of the user H approaches in the first position, and a nose recess 104T which is a recess to which the nose of the user H approaches in the second position. The nose recess 104B and the nose recess 104T are formed symmetrically with respect to a plane P1 which passes through the optical axes of the prisms 400L and 400R and is parallel to the X-axis direction and the Z-axis direction. By forming the nose recesses 104B and 104T, it is possible to provide a comfortable feeling of use in both the first position and the second position. The above-mentioned proximity sensor is provided, for example, in each of the nose recesses 104B and 104T. When the proximity sensor provided in the nose recess 104B detects the approach of an object (the nose of the user H), it can be determined that the posture is the first posture, and when the proximity sensor provided in the nose recess 104T detects the approach of an object (the nose of the user H), it can be determined that the posture is the second posture.

[0030] FIG. 6 is a diagram showing the rear and side of the display device 100. FIG. 6 corresponds to the first position. The display device 100 has an operation button 105 capable of accepting various operations such as instruction operations and power operations by the user H. When the cable insertion port 103 is arranged on one of the left side and the right side of the display device 100, it is preferable that the operation button 105 is provided on the side opposite to the side on which the cable insertion port 103 is provided. This allows the user H to hold the display device 100 in one hand and operate the operation button 105 with the hand holding the display device 100. In addition, compared to a case where the operation button is provided on the top or bottom surface of the display device 100, the operation button 105 can be operated by moving the finger more finely, and therefore erroneous operation can be suppressed.

[0031] Of the left and right sides of the display device 100, the side from which the cable 700 extends is difficult to grip. By providing the operation button 105 on the side opposite to the side on which the cable insertion port 103 is provided, the user H will naturally grip the side on which the operation button 105 is provided. Therefore, the user H can easily change the hand with which he or she holds the display device 100 and hold the display device 100 comfortably in either the first position or the second position.

[0032] A speaker 106L is provided at one end in the X-axis direction of the display device 100 (the rear surface of the exterior 101), and a speaker 106R is provided at the other end in the X-axis direction. The control board 600 outputs stereo sound from the speakers 106L and 106R, and inverts the sound output from the speaker 106L and the sound output from the speaker 106R between the first position and the second position. For example, in the first position, the control board 600 outputs sound for the left ear from the speaker 106L and the sound for the right ear from the speaker 106R. In the second position, the control board 600 outputs sound for the right ear from the speaker 106L and the sound for the left ear from the speaker 106R.

[0033] 7(A) and 7(B) are perspective views showing a state in which a user H wears the display device 100 on the head. FIG. 7(A) corresponds to a first position, and FIG. 7(B) corresponds to a second position. The head-mounted unit 800 is a mounting member that can be mounted on the head of the user H. By fixing (connecting) the display device 100 to the head-mounted unit 800, the user H can wear the display device 100 (the head-mounted unit 800 to which the display device 100 is fixed) on his / her head like a head-mounted display (HMD).

[0034] The display device 100 is provided with a connection part with the head mounted unit 800 so that the display device 100 can be fixed to the head mounted unit 800 in both the first and second positions. The arrangement and configuration of the connection part are not particularly limited, but in Figs. 7(A) and 7(B), the connection part 107T is provided on the part that becomes the upper surface of the display device 100 in the first position, and the connection part 107B is provided on the part that becomes the lower surface of the display device 100 in the first position. When the display device 100 is used in the first position, the head mounted unit 800 is connected to the connection part 107T (Fig. 7(A)), and when the display device 100 is used in the second position, the head mounted unit 800 is connected to the connection part 107B (Fig. 7(B)). The connection part 107T and the connection part 107B are provided symmetrically with respect to a plane P2 that passes through the center of the exterior 101 and is parallel to the X-axis direction and the Z-axis direction. This allows a hands-free video experience in both the first and second positions.

[0035] (Embodiment 2) Hereinafter, a second embodiment of the present invention will be described with reference to the drawings. Note that, in the following, a description of the same points as in the first embodiment (for example, the same configuration and processing as in the first embodiment) will be omitted, and only points different from the first embodiment will be described.

[0036] 8(A) and 8(B) are perspective views showing a part of the display device 110 according to the second embodiment. FIG. 8(A) corresponds to the first position, and FIG. 8(B) corresponds to the second position. The exterior 111 has a front opening 108 on the opposite side to the rear opening 102 (the portion where the prisms 400L and 400R are provided). Furthermore, the display device 110 has a light blocking member 900, which does not block the front opening 108 in one of the first position and the second position, and blocks the front opening 108 in the other of the first position and the second position. In the second embodiment, two front openings 108 corresponding to the cameras 500L and 500R, respectively, are formed. When the front opening 108 is not blocked, the cameras 500L and 500R are exposed by the front opening 108. In this case, the cameras 500L and 500R can capture the real space (surrounding environment). When the front opening 108 is blocked, the cameras 500L and 500R are covered by the front opening 108. In this case, the cameras 500L and 500R cannot capture images of the real space.

[0037] For example, as shown in Fig. 8(A), in the first position, the front opening 108 is not blocked and the cameras 500L and 500R are exposed. Then, as shown in Fig. 8(B), in the second position, the front opening 108 is blocked and the cameras 500L and 500R are hidden. The front opening 108 may not be blocked in the second position and may be blocked in the first position.

[0038] 9(A) and 9(B) are cross-sectional views showing the movement of the light blocking member 900. Fig. 9(A) corresponds to a first position, and Fig. 9(B) corresponds to a second position. For convenience, Fig. 9(B) shows the display device 110 upside down. The light blocking member 900 is attached to a rail 109 provided on an exterior 111, and moves in the direction of the arrow (along the rail 109) due to its own weight.

[0039] A weight may be provided at the end 901 of the light blocking member 900 to promote movement. The control board 600 may detect that the front opening 108 is blocked by the light blocking member 900 using the cameras 500L and 500R. Then, the control board 600 detects that the front opening 108 is blocked. When the brightness of the real space image obtained by the cameras 500L and 500R falls below a predetermined threshold, the control board 600 may stop the power supply to the cameras 500L and 500R. For example, when the brightness of the real space image obtained by the cameras 500L and 500R falls below a predetermined threshold, the control board 600 may stop the power supply to the cameras 500L and 500R. This makes it possible to reduce power consumption.

[0040] According to the above-described configuration of the second embodiment, it is possible to switch between displaying and not displaying a background image (real space image) without detecting the orientation of the display device 100.

[0041] Although an example in which two front openings 108 corresponding to cameras 500L and 500R are formed has been described, the present invention is not limited to this. For example, an illuminance sensor for detecting the brightness of the surroundings may be provided in display device 100, and an illumination opening corresponding to the illuminance sensor may be formed, and the illuminance sensor may be exposed or hidden by a shielding member. This allows the process that takes the brightness of the surroundings into consideration to be switched ON and OFF depending on the attitude of display device 100.

[0042] The above-described embodiment (including the modified examples) is merely an example, and the present invention also includes configurations obtained by appropriately modifying or changing the configurations of the above-described embodiment within the scope of the gist of the present invention. The present invention also includes configurations obtained by appropriately combining the configurations of the above-described embodiment.

[0043] For example, the positional relationship between the prism 410 and the display panel 310 may be devised as shown in Figures 10(A) and 10(B). Figure 10(A) is a cross-sectional view, and Figure 10(B) is a top view. Figures 10(A) and 10(B) correspond to a first position. In the first position, the prism 410 and the display panel 310 are used for the left eye. The shape and positional relationship of the prism and the display panel for the right eye are the left-right inversion of those of the prism 410 and the display panel 310, and therefore a description thereof will be omitted.

[0044] In FIG. 10A, the position CR1 of the optical axis of the prism 410 is shifted downward from the position CP1 of the center of the display panel 310 in the Y-axis direction. In this case, in the display panel 310, the range below the optical axis of the prism 410 (the optical axis of the eye 210 of the user H) corresponds to the angle θa, and the range above the optical axis of the prism 410 (the optical axis of the eye 210 of the user H) corresponds to the angle θb. The angle θa is greater than the angle θb. Therefore, the user H can observe a wide area below. This situation is preferable when observing an object placed below, such as a car.

[0045] In the second position, in the display panel 310, the range below the optical axis of the prism 410 (the optical axis of the eye 210 of the user H) corresponds to the angle θb, and the range above the optical axis of the prism 410 (the optical axis of the eye 210 of the user H) corresponds to the angle θa. Therefore, the user H can observe a wide area above. This situation is preferable when observing an object placed above, such as a device attached to the ceiling.

[0046] According to this configuration, the field of view can be switched in response to an inversion operation from one of the first attitude and the second attitude to the other.

[0047] (Other embodiments) The present invention can also be realized by a process in which a program for implementing one or more of the functions of the above-described embodiments is supplied to a system or device via a network or a storage medium, and one or more processors in a computer of the system or device read and execute the program. The present invention can also be realized by a circuit (e.g., ASIC) that implements one or more of the functions.

[0048] The disclosure of this embodiment includes the following configuration. (Configuration 1) A display device, comprising: a first eyepiece optical system that projects an image onto one of the user's right eye and left eye; a second eyepiece optical system that projects an image onto the other of the user's right eye and left eye; A detection unit that detects the attitude of the display device; A control unit that controls the image to be projected; having The control unit controls the projected image based on a detection result of the detection unit so as to project a first image in a first posture in which the user looks into the first eyepiece optical system with the right eye and the second eyepiece optical system with the left eye, and to project a second image different from the first image in a second posture in which the user looks into the second eyepiece optical system with the right eye and the first eyepiece optical system with the left eye.
