The error notification method is executed, for example, by blinking the lighting unit 12 of the control unit 10. The error notification may be executed via the image display unit 20 if possible. For example, when an audio signal can be supplied to the earphones 32 and 34 of the image display unit 20 via the audio processing unit 170, it is assumed that error notification is performed by outputting a sound for notifying an error from the earphones 32 and 34. Also good. Further, for example, when an image signal can be supplied to the display driving units 22 and 24 of the image display unit 20 via the image processing unit 160, the error notification is performed by causing the user to recognize an image that notifies the error. It may be. After the error notification, the control unit 10 turns off the power of the head-mounted display device 100 (step S250).

  When it is determined that the connection relationship is correct (that is, the control unit 10 can normally control the image display unit 20), the display control unit 190 of the control unit 10 displays the display control information of the individual information TI. Display control setting is performed according to SI (step S170). Specifically, the display control unit 190, based on the display control information SI included in the individual information TI, the resolution and frame rate of the right LCD 241 and the left LCD 242, the pixel arrangement, the scan (scanning) direction, the image quality adjustment item, the gamma value And the value of each identified item is set in the image processing unit 160.

  When the adjustment information AI is included in the individual information TI, the display control unit 190 determines the basic adjustment amount of the adjustment information AI as the image processing unit 160 or the right LCD control unit 211 or the left LCD control unit of the image display unit 20. Set to 212. Thereby, image quality adjustment for adjusting product variation is set. When the adjustment information AI includes information on the adjustment amount for each user, the adjustment amount for each user is set in addition to the basic adjustment amount. In addition, when the adjustment amount information for each user corresponding to a plurality of users is included as the adjustment amount information for each user, the user corresponding to one user selected by an arbitrary method Another adjustment amount may be set, or the control unit 10 specifies a user based on information acquired via the input information acquisition unit 110, and an adjustment amount for each user corresponding to the specified user is determined. It may be set.

  Next, the control unit 10 determines whether or not the display control setting is correct (step S180). If it is determined that the display control setting is not correct, is the number N1 determined to be incorrect less than a predetermined threshold T1? It is determined whether or not (step S190), and if it is less, display control setting is performed again (step S170). When the number of times N1 determined to be incorrect becomes equal to or greater than the predetermined threshold T1, the control unit 10 notifies the user of an error (step S240). The error notification method is the same as the error notification method when it is determined that the connection relation described above is not correct. After the error notification, the control unit 10 turns off the power of the head-mounted display device 100 (step S250).

  When it is determined that the display control setting is correct, the control unit 10 first starts up the image display unit 20 in a display off mode in which image display is not performed (step S200), and then the mode of the image display unit 20 is set. Is shifted to a display-on mode for displaying an image (step S210). Thereby, as shown in FIG. 3, the virtual image VI is displayed in the visual field VR of the user. In the display on mode, the control of the image display unit 20 by the control unit 10 is performed in the control mode set in the display control setting (step S170). When image quality adjustment is set in the display control setting, the control unit 10 causes the image display unit 20 to perform image quality adjustment in the set manner. In the display on mode, the user can manually adjust the image quality. When the user manually adjusts the image quality, the adjustment amount of each adjustment item is associated with the user identification information and stored in the adjustment information AI of the individual information TI.

  When the image display unit 20 is in the display on mode, the display control unit 190 of the control unit 10 reads the display control state from the image display unit 20 at a predetermined timing (step S220) and determines whether or not the control is normally performed. Confirm (step S230). When it is confirmed that the control is normally performed, the image display in the display on mode is continued (step S210).

  On the other hand, when it is determined that the display control state is not normal, the display control unit 190 of the control unit 10 performs display control setting (setting update) according to the display control information SI of the individual information TI (step update) S170), and then the display off mode (step S200) is entered and the display on mode is entered (step S210).

  In the head-mounted display device 100 according to the present embodiment described above, the image display unit 20 includes the storage unit 29 that stores the individual information TI. The individual information TI is information for specifying a control mode (for example, resolution, frame rate, pixel arrangement, scan direction, image quality adjustment item, gamma value, etc.) of the image display unit 20 by the control unit 10. The control unit 10 reads the individual information TI from the storage unit 29 of the image display unit 20 and controls the image display unit 20 in a control manner according to the read individual information TI. Therefore, in the head-mounted display device 100 according to the present embodiment, for example, an arbitrary set of the control unit 10 and the image display unit 20 is selected from the plurality of control units 10 and the plurality of image display units 20. Even in the case of use, it is possible to suppress the control failure of the image display unit 20 by the control unit 10 due to the difference in the model of the image display unit 20 or the like while suppressing the complexity of the configuration and control.

  In the head-mounted display device 100 according to the present embodiment, the adjustment information AI can be included in the individual information TI stored in the storage unit 29 of the image display unit 20. The adjustment information AI is information regarding image quality adjustment of a virtual image recognized by the user by the image display unit 20. When the adjustment information AI is included in the individual information TI, the control unit 10 causes the image display unit 20 to perform image quality adjustment in a manner specified by the adjustment information AI. Therefore, in the head-mounted display device 100 according to the present embodiment, for example, an arbitrary set of the control unit 10 and the image display unit 20 is selected from the plurality of control units 10 and the plurality of image display units 20. Even when used, the control unit 10 can adjust the image quality so as to compensate for the product characteristics of the currently connected image display unit 20 (optical characteristics of the apparatus, output level of the power source, light source characteristics, etc.) Image quality degradation can be easily suppressed.

  In the head-mounted display device 100 according to the present embodiment, the adjustment information AI can include information indicating the adjustment amount for each user stored in the storage unit 29 in the course of use by the user. The unit 10 identifies the user and causes the image display unit 20 to perform image quality adjustment based on the user-specific adjustment amount corresponding to the identified user. Therefore, in the head-mounted display device 100 according to the present embodiment, for example, an arbitrary set of the control unit 10 and the image display unit 20 is selected from the plurality of control units 10 and the plurality of image display units 20. Even in use, image quality adjustment according to the user's preference can be easily performed.

  In the head-mounted display device 100 according to the present embodiment, the control unit 10 performs display control setting (setting update) based on the individual information TI when it is determined that the display control state is not normal. For example, even when a malfunction such as cable disconnection occurs, it can be automatically restored, and convenience can be improved.

  In the head-mounted display device 100 according to the present embodiment, the control unit 10 determines that the image display unit 20 cannot be normally controlled, or the display control of the image display unit 20 by the control unit 10. When it is determined that the setting is not correct, the control unit 10 notifies the user of an error via blinking of the lighting unit 12 of the control unit 10, audio output in the image display unit 20, image display, or the like. Therefore, in the head-mounted display device 100 according to the present embodiment, the user is made to recognize a connection correspondence problem between the control unit 10 and the image display unit 20 in the head-mounted display device 100 and a problem related to display control. If necessary, it is possible to prompt a response and improve convenience.

  FIG. 8 is a flowchart showing a flow of control processing of the head-mounted display device 100a in the second embodiment. The processing from step S310 to step S340 shown in FIG. 8 is the same as the processing from step S110 to step S140 of the first embodiment shown in FIG. In the control process of the second embodiment, step S350, step S360, and step S370 shown in FIG. 8 are different from the control process of the first embodiment. Further, the processing from step S380 to step S450 shown in FIG. 8 is the same as the processing from step S180 to step S250 of the first embodiment.

  When the display control unit 190 of the control unit 10a reads the individual information TIa from the storage unit 29a of the image display unit 20a and stores the individual information TIa in a predetermined area of the storage unit 120 (step S340), it is included in the individual information TIa. Based on the device information DI, it is determined whether or not the type of the image display unit 20a is a type corresponding to the control unit 10a (step S350). This determination is a determination as to whether or not the control unit 10a can normally control the image display unit 20a. Specifically, the display control unit 190 specifies the type of the image display unit 20 based on, for example, the device information DI, and displays the image depending on whether or not the type of the image display unit 20a is a type corresponding to the control unit 10a. It is determined whether an image can be displayed on the unit 20a.

  When it is determined that the image display unit 20a is not the type of the image processing apparatus corresponding to the control unit 10a (that is, the control unit 10a cannot normally control the image display unit 20a) (step S350: NO) ), The control unit 10a notifies the user of an error (step S440).

  If it is determined that the image display unit 20a is the type of the image processing apparatus corresponding to the control unit 10a (step S350: YES), whether or not the image display unit 20a is a model corresponding to the control unit 10a. Is determined (step S360). The display control unit 190 of the control unit 10a determines whether or not the image display unit 20a is a model compatible with the control unit 10a based on the model identification information PI included in the individual information TIa. This determination is also a determination of whether or not the control unit 10a can normally control the image display unit 20a. Specifically, the display control unit 190 specifies the model of the image display unit 20a based on the model identification information PI, for example, and determines whether the model of the image display unit 20a is a model corresponding to the control unit 10a. It is determined whether or not an image can be displayed on the display unit 20a.

  When it is determined that the image display unit 20a is a model compatible with the control unit 10a (that is, the control unit 10a can normally control the image display unit 20a) (step S360: YES), control is performed. The unit 10a performs display control setting processing (step S370).

  FIG. 9 is a flowchart showing the flow of display control setting processing in the second embodiment. In the display control setting process, the display control unit 190 of the control unit 10a first performs display control setting for realizing two-dimensional (2D) display (step S510).

  Thereafter, the control unit 10a receives an instruction for selecting a three-dimensional (3D) display of the image by the user (step S520). The user can instruct selection of 3D display of an image by operating the control unit 10a. If the user has not instructed selection of 3D display (step S520: NO), the display control unit 190 continues to perform display control settings for 2D display.

  When there is a 3D display selection instruction from the user (step S520: YES), the display control unit 190 of the control unit 10a displays the image on the image display unit 20a based on the display control information SIa included in the individual information TIa. Whether or not can be displayed in 3D is determined (step S530). If the image display unit 20a determines that the image cannot be displayed in 3D based on the display control information SIa (step S530: NO), the control unit 10a notifies the user of an error (step S550), and the display control unit 190 Continues the 2D display control setting. The error notification may be displayed as an image on the image display unit 20a, or may be notified by voice through the earphones 32 and 34.

  When the image display unit 20a determines that the image can be displayed in 3D based on the display control information SIa (step S530: YES), the display control unit 190 performs display control settings for 3D display (step S540), and displays the image. The control setting process ends. In the case of 3D display, unlike the display control setting of 2D display, the image light guided to the user's right eye and the image light guided to the left eye are different in order to make the user visually recognize the 3D display.

  As described above, in the control unit 10a of the second embodiment, the control mode of the image display unit 20a connected to the control unit 10a (for example, the type, model, resolution, frame rate, pixel arrangement, scan, etc. of the image processing apparatus) Individual information TIa specifying the direction, image quality adjustment item, gamma value, etc.) is acquired from the image display unit 20a. Then, the image display unit 20a is controlled based on the acquired individual information TIa. Therefore, the control part 10a of 2nd Example can implement | achieve control of the various image display parts 20a by one control part 10a.

  Further, in the control unit 10a of the second embodiment, when it is determined that the image display unit 20a is not the type of the image processing apparatus corresponding to the control unit 10a, or is not a model corresponding to the control unit 10a, the control is performed. The control unit 10 notifies the user of an error through blinking of the lighting unit 12 of the unit 10, sound output in the image display unit 20a, image display, or the like. Therefore, in the control unit 10a, the user can recognize the problem of the connection correspondence between the control unit 10a and the image display unit 20a and the problem related to display control, and can prompt the user if necessary, thereby improving convenience. Can do.

  In the display control setting process in the second embodiment, first, display setting control in 2D display is performed. When there is an operation from the user to the control unit 10a, the control unit 10a can switch between 2D display and 3D display according to a selection instruction from the user. On the other hand, when it is determined that the image display unit 20a cannot perform 3D display based on the display control information SIa of the individual information TIa, the control unit 10a continues the display control setting for 2D display. Therefore, in the control unit 10a of the second embodiment, when the image display unit 20a can perform 3D display, the user can freely select an image for 2D display or 3D display according to the intention of the user. Can be provided. In addition, in the control unit 10a of the second embodiment, when the image display unit 20a cannot perform 3D display, a 2D display image is automatically displayed on the image display unit 20a. Therefore, the user needs extra operations. It is possible to display an appropriate image without using it.

  Moreover, in the control part 10a of 2nd Example, the image display part 20a has the memory | storage part 29a which stores the separate information TIa. The individual information TIa is information for specifying a control mode (for example, device type, model, resolution, frame rate, pixel alignment, scan direction, image quality adjustment item, gamma value, etc.) of the image display unit 20a by the control unit 10a. . The control unit 10a reads the individual information TIa from the storage unit 29a of the image display unit 20a, and controls the image display unit 20a in a control manner according to the read individual information TIa. Therefore, in the control unit 10a of the second embodiment, for example, an arbitrary set of the control unit 10a and the image display unit 20a is selected and used from among the plurality of control units 10a and the plurality of image display units 20a. In addition, it is possible to suppress the control defect of the image display unit 20a by the control unit 10a due to the difference in the model of the image display unit 20a and the like while suppressing the complexity of the configuration and control.

FIG. 12 is an explanatory diagram showing an external configuration of the car navigation device 60. The control unit 10c is connected to the car navigation device 60 by wireless communication. The control unit 10 c reads the individual information TIc from the storage unit 29 c of the car navigation device 60 and stores the individual information TIc in a predetermined area of the storage unit 120. Thereafter, the control unit 10c performs display control setting processing based on the device information DI, the model identification information PI, the display control information SIc, and the adjustment information AI included in the individual information TIc. Therefore, in this control unit 10c, the user can use content data such as a navigation program without installing an unnecessary configuration in the car navigation device 60. In addition, although the control part 10c is provided with the power supply 130, the structure supplied with a power supply from the cigarette lighter etc. with which the car navigation apparatus 60 was equipped may be sufficient.

  An image display unit having another shape such as a projection display device that displays an image on a projection surface by projection, a navigation display device, or an image display unit worn like a hat may be employed. If it is the image display part 20 in the said Example, since the control part 10 controls, the weight of the image display part 20 can be made light and a user's wearability can be improved. In addition, by connecting the control device of the present invention to a monitor of a personal computer, a mobile phone or the like, an image display device can be selected according to the purpose, and convenience for the user can be enhanced. The earphones 32 and 34, which are sound sources, may be omitted, or sound may be output by connecting the control device to a sound source such as a speaker.

  In the above embodiment, the head-mounted display device 100 is a binocular optically transmissive head-mounted display device. However, the present invention can be applied to, for example, a video transmission type, a non-transmission type, or a monocular type. The present invention can be similarly applied to other types of head mounted display devices.

  In the above embodiment, a part of the configuration realized by hardware may be replaced by software, and conversely, a part of the configuration realized by software may be replaced by hardware. Good. For example, in the above embodiment, the image processing unit 160 and the sound processing unit 170 are realized by the CPU 140 reading and executing a computer program. However, these functional units may be realized by a hardware circuit. Good.

  In addition, when part or all of the functions of the present invention are realized by software, the software (computer program) can be provided in a form stored in a computer-readable recording medium. In the present invention, the “computer-readable recording medium” is not limited to a portable recording medium such as a flexible disk or a CD-ROM, but an internal storage device in a computer such as various RAMs and ROMs, a hard disk, etc. It also includes an external storage device fixed to the computer.

D2. Modification 2:
In the above embodiment, the head-mounted display device 100 may guide the image light representing the same image to the left and right eyes of the user to make the user visually recognize the two-dimensional image, or the left and right eyes of the user. Alternatively, image light representing different images may be guided to allow the user to visually recognize the three-dimensional image.

  In the display control setting process of the second embodiment, first, the display control setting of 2D display is performed. When the selection instruction by the user is received, if the image display unit 20a supports 3D display, the 3D display is set. Although the display control setting is performed, switching between 2D display and 3D display is not limited to this. For example, a selection instruction for 2D display and 3D display may be performed at the beginning of display control setting. In this case, when there is no selection instruction by the user, the display control unit 190 may set display control to automatically continue 2D display after a predetermined time has elapsed. Further, when an operation from a user is accepted during 3D display, switching to 2D display display control setting may be performed. As a display control setting switching method, the control unit 10a has a configuration capable of recognizing voice (for example, a microphone or the like), and may switch between 2D display and 3D display according to the voice of the user. In addition, the user is informed to the user that the image display unit 20a is compatible with 3D display via the earphones 32 and 34, or is notified to the user by the lighting unit 12 of the control unit 10a.

D3. Modification 3:
The content of the individual information TI (FIG. 4) in the above embodiment is merely an example, and some items may not be included in the individual information TI, and other items may be included. For example, the individual information TI may not include the adjustment information AI.

  In addition, the individual information TI does not include the display control information SI. Instead, the storage unit 120 of the control unit 10 stores the correspondence relationship between each model of the image display unit 20 and the control mode of the image display unit 20 by the control unit 10. (Model-specific display control information) may be stored. In this case, the control unit 10 specifies the model of the image display unit 20 based on the model identification information PI of the individual information TI read from the storage unit 29 of the image display unit 20 and stores it in the storage unit 120 of the control unit 10. In the specified model-specific display control information, the image display unit 20 may be controlled in a control mode corresponding to the model of the specified image display unit 20.
