It is determined whether or not it has been performed (step S1). Here, when either the opening or closing operation of the left support temple 44 or the right support temple 45 is performed, the CPU 21 closes the operation when the left support temple 44 or the right support temple 45 shifts from the open state to the closed state. It is determined whether the operation is the opening operation or the opening operation in which both the left support temple 44 and the right support temple 45 shift to the open state (step S2).

In step S2, the criterion for determining that the operation is the closing operation is satisfied when one of the left support temple 44 and the right support temple 45 shifts from the open state to the closed state.

This closing operation is performed when the user stops using or stops using the HMD 1 while using the HMD 1.
1 is removed from the head (at this time, the left support temple 44 and the right support temple 45 are in the open state shown in FIG. 3),
This is performed by turning the left support temple 44 or the right support temple 45 to a closed state (a state shown in FIG. 4).

On the other hand, in step S2, the criterion of the opening operation is that one or both of the left support temple 44 and the right support temple 45 shift from the closed state to the open state, and as a result of the shift, It is a condition that the supporting temple is also in the opened state.

This opening operation is performed when the HMD 1, the controller 2 and the like are not operating, that is, in a state where the power supply to them is stopped, and the left supporting temple 44 or the right supporting temple 45 or both in the closed state. This is done by opening the temple.

1) Return to step S1 and wait for a detection signal from the temple state detection unit 43 again.

If the operation of the left support temple 44 or the right support temple 45 is an opening operation in step S2, the CPU 21 determines in step S4 whether the head-mounted image display device is energized. Determine whether or not. If it is in the energized state, the process returns to step S1 and waits for a detection signal from the temple state detecting unit 43 again.

In step S4, when the head mounted video display device is not energized, that is, when the HM
When the left support temple 44 or the right support temple 45 is opened when both D1 and the controller 2 are inactive, the CPU 21 first supplies power to the HMD 1 and the controller 2 (step S6), and then, External devices such as the video player 3 are connected, and power is supplied to these devices if necessary (step S7). After this, the CPU
21 returns to step S1 and waits for a detection signal from the temple state detection unit 43 again.

On the other hand, if the opening / closing operation of the left support temple 44 or the right support temple 45 is not performed in step S1, the CPU 21 determines in step S3 whether the manual power switch 24 has been operated. If the manual power switch 24 has not been operated, the process returns to step S1 and waits for a detection signal from the temple state detection unit 43.

If the manual power switch 24 has been pressed in step S3, the CPU 21 subsequently determines whether or not the head mounted video display device is in the energized state (step S12).

Here, when the power is on, the CPU 2
1 determines that the operator has operated the manual power switch 24 to bring the head-mounted video display device from the operating state to the stopped state, and firstly, to the external device such as the connected video player 3 or the like. The power supply is stopped (step S10), and then the power supply to each circuit unit of the HMD 1 and the controller 2 is stopped (step S11), and the process returns to the step S1 and returns from the temple state detection unit 43 again. Wait for the detection signal.

On the other hand, if the power is not on in step S12, the CPU 21 determines that the operator has operated the manual power switch 24 to bring the head-mounted image display device in a stopped state into operation. First, HMD
1. Power is supplied to the controller 2 (step S6),
Subsequently, external devices such as the video player 3 are connected, and power is supplied to these devices if necessary (step S7). Thereafter, the CPU 21 returns to the step S1 and waits for a detection signal from the temple state detection unit 43 again.

As described above, the head mounted video display apparatus of the first embodiment controls the power supply of the apparatus. Here, a specific use situation will be considered.

First, it is assumed that the user wears the HMD 1 on his / her head and watches an image. Now, it is assumed that the user needs to temporarily remove the HMD 1 from the head for some reason. At this time, when it is not enough to stop the power supply of the apparatus, the user sets the HMD 1 with both the left support temple 44 and the right support temple 45 open.
