Information to be displayed.

A-2. Control processing:
FIG. 5 is a flowchart showing the flow of control processing of the head-mounted display device 100 in the present embodiment. The control process is a process in which the control unit 10 controls image display by the image display unit 20. When the user presses the power switch 18 to turn on the power of the head-mounted display device 100 (step S110), the control unit 10 sets the head-mounted display device 100 to the sleep mode (step S120), and each device. The initial control is performed (step S130). At this time, the virtual image VI is not yet displayed in the visual field VR of the user.

  Next, the display control unit 190 of the control unit 10 reads the individual information TI from the storage unit 29 of the image display unit 20 that is currently connected to the control unit 10, and the read individual information TI is stored in, for example, a predetermined unit of the storage unit 120. (Step S140). Note that the control unit 10 confirms the consistency of the read individual information TI by, for example, error detection, and reads the individual information TI from the storage unit 29 again when the read individual information TI is inconsistent. Also good. Further, if the consistency check of the individual information TI is not completed even after a predetermined number of readings, the power may be forcibly turned off.

  Next, the display control unit 190 of the control unit 10 determines whether or not the connection relationship between the control unit 10 and the image display unit 20 is correct based on the model identification information PI included in the individual information TI (step S150). . This determination is a determination as to whether or not the control unit 10 can normally perform image display control by the image display unit 20. Specifically, the display control unit 190 identifies the model of the image display unit 20 based on, for example, the model identification information PI, and determines whether the model of the image display unit 20 is a model corresponding to the control unit 10 or not. Determine if the relationship is correct.

  When it is determined that the connection relationship is not correct (that is, the control unit 10 cannot normally control the image display by the image display unit 20), the control unit 10 notifies the user of an error ( Step S240). 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 by the image display unit 20), the display control unit 190 of the control unit 10 displays the individual information TI. Display control setting is performed according to the display control information 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.
