As a result, the management unit 240 determines that the signal received by the second transmission / reception unit 220 of the display device 200 is a stop signal transmitted from the first eyeglass device 310. Thereafter, the management unit 240 updates the data in the status column corresponding to the first eyeglass device 310 in the management list from “power feeding” to “power feeding stopped”. Similarly, the management unit 240 of the display device 200 that has received the stop signal by the third transmission / reception unit 330 of the second spectacle device 320 receives the unique identification information included in the stop signal and a plurality of spectacle devices 300 stored in advance in the management list. Is compared with the unique identification information. As a result, the management unit 240 determines that the signal received by the second transmission / reception unit 220 of the display device 200 is a stop signal transmitted from the second eyeglass device 320. Thereafter, the management unit 240 updates the data in the status column corresponding to the second eyeglass device 320 in the management list from “power feeding” to “power feeding stopped”. Thus, the management unit 240 can move the movable eyeglass device that can execute the auxiliary operation from among the plurality of eyeglass devices 300 based on the start signal and the stop signal including the unique identification information, and the immobility that cannot execute the auxiliary operation. The eyeglass device can be specified.

  The management unit 240 outputs the updated management list to the second control unit 250. Thereafter, process step S630 is performed.

(Processing step: S630)
FIG. 10 schematically illustrates operations of the display device 200 and the first spectacle device 310 when the management unit 240 identifies a single movable spectacle device (first spectacle device 310) in the process step S620. Processing steps S630 to S660 when the management unit 240 identifies a single movable eyeglass device will be described with reference to FIGS. The operation of the display device 200 when the management unit 240 specifies a plurality of movable eyeglass devices in the processing step S620 will be described later together with the GUI processing routine R700.

  FIG. 10A schematically shows the operation of the display device 200 when the GUI is not displayed on the display 210. FIG. 10B schematically shows the operation of the display device 200 when the GUI is displayed on the display 210.

  A section (A) in FIG. 10 shows a video signal for displaying a video on the display 210. A section (B) in FIG. 10 shows a synchronization signal transmitted from the second transmission / reception unit 220. The section (C) in FIG. 10 shows the variation in the amount of transmitted light allowed by the left eye shutter 341 of the first eyeglass device 310. A section (D) in FIG. 10 shows a variation in the amount of transmitted light allowed by the right eye shutter 342 of the first eyeglass device 310.

  Based on the management list input from the management unit 240 and the output result from the GUI processing routine R700, the second control unit 250 displays the display timing of the frame image on the display 210 and the left eye shutter 341 and the right eye of the eyeglass device 300. The opening / closing timing of the shutter 342 is determined.

  The frame image displayed on the display 210 is represented by the first frame image (see FIG. 10B) expressed by the L signal or R signal and the GUI signal, and expressed by the L signal or R signal without using the GUI signal. The second frame image (see FIG. 10A) is included. When the output result from the GUI processing routine requests GUI display, the second control unit 250 controls the video processing unit 233 so that the first frame image is displayed. When the output result from the GUI processing routine does not request display of the GUI, the second control unit 250 controls the video processing unit 233 so that the second frame image is displayed.

  The second control unit 250 controls the display timing of the left eye frame image represented by the L signal and the right eye frame image represented by the R signal, in addition to the above-described control related to GUI display / non-display. In the present embodiment, when the output result from the GUI processing routine requests GUI display, a left eye frame image with GUI (first frame image) and a right eye frame image with GUI (first frame image) are displayed. The second control unit 250 outputs a control signal to the video processing unit 233 so as to be displayed at the determined timing. In addition, when the output result from the GUI processing routine does not request GUI display, a left eye frame image (second frame image) that does not include a GUI and a right eye frame image (second frame image) that does not include a GUI are determined. The second control unit 250 outputs a control signal to the video processing unit 233 so as to be displayed at the timing.

  When the output result from the GUI processing routine does not request the display of the GUI, the video processing unit 233 uses the control signal from the second control unit 250 and the video signal from the playback unit 232 to match the video image suitable for the display 210. A signal is generated, and then the generated video signal is output to the display 210. As a result, the display 210 displays the second frame image.

  When the output result from the GUI processing routine requests display of the GUI, the video processing unit 233 adds the control signal from the second control unit 250 and the video signal from the reproduction unit 232, as well as the GUI from the generation unit 260. Based on the signal, a video signal suitable for the display 210 is generated, and then the generated video signal is output to the display 210. As a result, the display 210 displays the first frame image.

  In order to determine the opening / closing timing of the left eye shutter 341 and the right eye shutter 342 of the eyeglass device 300, the second control unit 250 controls the generation timing of the synchronization signal by the transmission control unit 234. When the spectacle device 300 specified as the movable spectacle device by the management unit 240 is only the first spectacle device 310 (that is, when the second spectacle device 320 is specified as the non-movable spectacle device), the transmission control unit 234 generates The synchronization signal is a pulse signal OL1 for opening the left eye shutter 341 of the first eyeglass device 310, a pulse signal CL1 for closing the left eye shutter 341 of the first eyeglass device 310, and the right eye of the first eyeglass device 310. A pulse signal OR1 for opening the shutter 342 and a pulse signal CR1 for closing the right eye shutter 342 of the first eyeglass device 310 are included.

  The second control unit 250 controls the transmission control unit 234 so that the pulse signal OL1 is transmitted from the second transmission / reception unit 220 at the timing when the display of the left eye frame image starts. The second control unit 250 controls the transmission control unit 234 so that the pulse signal CL1 is transmitted from the second transmission / reception unit 220 at the timing when the display of the left eye frame image ends. The second control unit 250 controls the transmission control unit 234 so that the pulse signal OR1 is transmitted from the second transmission / reception unit 220 at the timing when the display of the right eye frame image starts. The second control unit 250 controls the transmission control unit 234 so that the pulse signal CR1 is transmitted from the second transmission / reception unit 220 at the timing when the display of the right eye frame image ends. The second controller 250 outputs a control signal to the transmission controller 234 so that transmission of the pulse signals OL1, CL1, OR1, and CR1 is achieved. Thereafter, process step S640 is executed.

(Processing step: S640)
The transmission control unit 234 generates a synchronization signal including the pulse signals OL1, CL1, OR1, and CR1 based on the control signal from the second control unit 250. Subsequently, the transmission control unit 234 outputs the generated synchronization signal to the second transmission / reception unit 220. Thereafter, process step S650 is performed.

(Processing step: S650)
The second transmission / reception unit 220 transmits the synchronization signal output from the transmission control unit 234 to the eyeglass device 300. For example, wireless communication defined in IEEE802.11 is used for transmission of the synchronization signal. When the movable spectacle device specified by the status column of the management list output from the management unit 240 is only the first spectacle device 310, the pulse signal OL1 according to the IP address of the first spectacle device 310 recorded in the management list. , CL1, OR1, and CR1 are output. When the movable spectacle device identified by the status column of the management list output from the management unit 240 is only the second spectacle device 320, a transmission process is performed according to the IP address of the second spectacle device 320 recorded in the management list. . The transmission process when there are a plurality of movable eyeglass devices specified by the status column of the management list output from the management unit 240 will be described later together with the GUI processing routine R700.

The signal is opened / closed in response to reception of pulse signals OL1, CL1, OR1, and CR1 by unit 330. Thus, the viewer can appropriately view the left eye frame image and the right eye frame image. After the transmission process of the synchronization signal by the second transmission / reception unit 220, the process step S660 is executed.

(Processing step: S660)
The second control unit 250 determines whether or not the reproduction of the content data has ended based on the video signal output from the reproduction unit 232. If the reproduction of the content data has not ended, the process returns to processing step S610. When the reproduction of the content data is finished, the processing by the display device 200 is completed.

  When the signal is not received for a predetermined time in the processing step S610, the display timing of the left eye frame image and the right eye frame image not including the GUI is determined in the processing step S630. In processing step S640, a synchronization signal is generated in accordance with the determined display timing. In the processing step S650, the generated synchronization signal is output to the first spectacle device 310 and the second spectacle device 320. Thereafter, processing step S660 is executed, and when the reproduction of the content data is completed, the processing by the display device 200 is completed.

(Interlocking between operation device, display device and eyeglass device)
FIG. 11 is a flowchart schematically showing a transmission operation of the first control signal by the controller device 400. The transmission operation of the first control signal of the controller device 400 will be described with reference to FIGS. 1, 6, 7, and 11.

  As described above, when the viewer operates the switch 432 of the operation device 400, the switch 432 outputs a start signal notifying the start of power feeding to the first control unit 433. Thereafter, processing step S810 is started.

(Processing step: S810)
The first controller 433 waits for a start signal from the switch 432. When the first control unit 433 detects the input of the start signal from the switch 432, the process step S820 is started. The first control unit 433 maintains the standby mode until a start signal from the switch 432 is input.

(Processing step: S820)
The first control unit 433 to which the start signal from the switch 432 is input controls the power supply circuit so that power is supplied from the battery 431 to the entire operation device 400. As a result, each component of the controller device 400 performs a predetermined operation. For example, the first transmission / reception unit 420 can execute transmission / reception of signals under the control of the first control unit 433. The first control unit 433 that has controlled the start of power supply from the battery 431 to the entire operation device 400 outputs a start signal to the first transmission / reception unit 420. Thereafter, processing step S830 is started.

(Processing step: S830)
The first control unit 433 waits for a stop signal from the switch 432 or an operation signal from the button 410. When the viewer operates the button 410 of the operation device 400 and selects, for example, the first spectacle device 310 (see FIG. 7), the button 410 indicates to the first controller 433 that the first spectacle device 310 has been selected. A selection signal including selection information to be expressed is output to the first control unit 433. When the viewer operates the button 410 of the operation device 400 so as to cancel the selection of the first eyeglass device 310 described above, the button 410 is released to the first control unit 433 and the selection of the first eyeglass device 310 is released.

When the first control unit 433 determines that the signal input from the button 410 is a selection signal, the process step S850 is started. When the first control unit 433 determines that the signal input from the button 410 is an operation signal, the process step S860 is started.

(Processing step: S850)
The first control unit 433 analyzes selection information included in the selection signal. When the selection information represents selection of the first spectacle device 310 or the second spectacle device 320, the first control unit 433 stores the selection information in a nonvolatile recording medium included in the first control unit 433. When the selection information represents the cancellation of the selection for the first spectacle device 310 or the second spectacle device 320, the first control unit 433 deletes the selection information stored in the storage medium. Thereafter, the process step S830 is performed again.

(Processing step: S860)
After the selection information is stored in the processing step S850, when an operation signal is input from the button 410 to the first control unit 433 in the processing step S830, the processing step S860 is executed as a result of the determination processing in the processing step S840. . The first control unit 433 generates a first control signal based on the selection information stored in the recording medium, the operation information included in the operation signal, and the unique identification information of each eyeglass device 300 stored in advance in the storage unit 440. . For example, when the viewer selects the first eyeglass device 310, the first control unit 433 generates a first control signal including the unique identification information and the operation information assigned to the first eyeglass device 310. For example, when the viewer selects the second eyeglass device 320, the first control unit 433 generates a first control signal including unique identification information and operation information assigned to the second eyeglass device 320.

  The operation device 400 may include a notification unit that notifies the viewer that a selection operation of the first spectacle device 310 or the second spectacle device 320 is necessary. As the notification unit, for example, a light emitting element that emits light from the display window 434, a vibration element that vibrates the operation device 400, or a sound element that generates sound from the operation device 400 is applied. As a result, the viewer is appropriately prompted to select the first spectacle device 310 or the second spectacle device 320. Thus, the generation of the first control signal is preferably performed.

The

  Through the first auxiliary operation synchronized with the display of the first frame image, the viewer wearing the first eyeglass device 310 (that is, the non-operator) views the first frame image for the left eye with the left eye, The first frame image for eyes is viewed with the right eye. Thus, the viewer wearing the first eyeglass device 310 can perceive the video expressed by the L signal and the R signal output from the playback unit 232 in three dimensions while viewing the GUI. On the other hand, as described above, the second spectacle device 320 does not react to the pulse signals OL1, CL1, OR1, and CR1, and thus the second spectacle device 320 is configured as an optical filter unit while the first frame image is displayed. The amount of light transmitted through 340 is maintained at a low level. Thus, viewing of a frame image with a GUI by a viewer wearing the second eyeglass device 320 (that is, a viewer who does not operate the operation device 400) is appropriately suppressed.

Thus, the viewer wearing the second glasses apparatus 320 can perceive the video expressed by the L signal and the R signal output from the playback unit 232 in three dimensions without viewing the GUI. On the other hand, as described above, the first spectacle device 310 does not react to the pulse signals OL2, CL2, OR2, and CR2, and therefore, the first spectacle device 310 is in the optical filter section while the second frame image is displayed. The amount of light transmitted through 340 is maintained at a low level. Thus, viewing of the frame image not including the GUI by the viewer wearing the first eyeglass device 310 (that is, the viewer operating the operation device 400) is appropriately suppressed.

  As described above, when the management unit 240 identifies a plurality of movable spectacle devices and the second transmission / reception unit 220 receives the first control signal from the operation device 400, the first spectacle device 310 and the second spectacle device 320 are activated.

Thereafter, the second control unit 250 refers to the “synchronized image” column of the first eyeglass device 310 in the management list output from the management unit 240 and generates a binocular frame image exemplified as the first image. Determine to synthesize the GUI generated by 260. The video processing unit 233 synthesizes the binocular frame image and the GUI under the control of the second control unit 250, and generates a video signal for displaying the first frame image. After that, as shown in FIG. 17, the L signal and the R signal for representing the “J” -th generated left eye frame image and right eye frame image, respectively, are sequentially output to the display 210, and then the GUI. A video signal for expressing the attached binocular frame image is output. Thereafter, an L signal and an R signal for representing the “J + 1” th generated left eye frame image and right eye frame image are sequentially output to the display 210.

By comparing the unique identification information of the eyeglass device 320 with the unique identification information of each eyeglass device 300 in the management list output from the management unit 240, it is specified that the second eyeglass device 320 is an operation eyeglass device. . Thereafter, the second control unit 250 refers to the “synchronized image” field of the second eyeglass device 320 in the management list output from the management unit 240, and performs the left eye frame image and the right eye exemplified as the second image. It is determined that the GUI generated by the generation unit 260 is combined with the frame image. Under the control of the second control unit 250, the video processing unit 233 combines the left eye frame image / right eye frame image and the GUI, and generates a video signal for displaying the first frame image.

  When the viewer wearing the first spectacle device 310 and the viewer wearing the second spectacle device 320 watch different videos, the display device does not depend on whether to display or not display the GUI in the processing step S730. 200 transmits a first synchronization signal used exclusively for controlling the optical filter unit 340 of the first eyeglass device 310 and a second synchronization signal used exclusively for controlling the optical filter unit 340 of the second eyeglass device 320. .
