EYEWEAR DEVICE, DISPLAY DEVICE, VIDEO SYSTEM COMPRISING EYEWEAR DEVICE AND DISPLAY DEVICE, AND VIDEO SYSTEM CONTROL METHOD
The instant application discloses an eyewear device including: a light amount adjuster which adjusts a light amount transmitted to left and right eyes of an observer to perform assistance operation that assists in observing a video so that the video is stereoscopically perceived; a battery portion which stores power for the light amount adjuster to perform the assistance operation; and a transmitter configured to transmit a notification signal for notifying a condition of the battery portion. The notification signal contains charge information, which indicates whether or not the battery portion is being charged, and remaining level information, which indicates a power amount stored in the battery portion.
1 . An eyewear device comprising:
a light amount adjuster which adjusts a light amount transmitted to left and right eyes of an observer to perform an assistance operation that assists in observing a video so that the video is stereoscopically perceived;
a battery portion which stores power for the light amount adjuster to perform the assistance operation; and
a transmitter configured to transmit a notification signal for notifying a condition of the battery portion, wherein
the notification signal contains charge information, which indicates whether or not the battery portion is being charged, and remaining level information, which indicates a power amount stored in the battery portion.
2 . The eyewear device according to claim 1 , wherein
the remaining level information indicates at least one of first remaining level information, which represents a ratio of the power amount to a maximum power storage amount that the battery portion is capable of storing, and second remaining level information, which represents a period of time for the light amount adjuster to perform the assistance operation in response to the power amount.
3 . A display device comprising:
a receiver configured to receive a notification signal for notifying a condition of an eyewear device which performs an assistance operation to assist in observing a video so that the video is stereoscopically perceived;
an image generator configured to generate a condition image which represents the condition of the eyewear device in response to the notification signal received by the receiver; and
a display portion configured to display the condition image, wherein
the notification signal contains charge information, which indicates whether or not the eyewear device is being charged, and remaining level information, which indicates a power amount stored in the eyewear device, and
the image generator generates a power amount image, which represents the power amount stored in the eyewear device, as the condition image if the charge information indicates that the eyewear device is not being charged.
4 . The display device according to claim 3 , wherein
if the image generator generates the power amount image, the display portion displays at least one of a first power amount image, which represents a ratio of the power amount to a maximum power storage amount that the eyewear device is capable of storing, and a second power amount image, which represents a period of time for the eyewear device to perform the assistance operation in response to the power amount, as the power amount image.
5 . The display device according to claim 3 , wherein
if the charge information indicates that the eyewear device is being charged, the image generator generates a charge image, which represents that the eyewear device is being charged, as the condition image.
6 . A video system comprising:
a display device configured to display a video which is stereoscopically perceived by an observer; and
an eyewear device configured to perform an assistance operation which assists in observing the video so that the video is stereoscopically perceived, wherein
the eyewear device includes:
a light amount adjuster which adjusts a light amount transmitted to left and right eyes of the observer to perform the assistance operation;
a battery portion which stores power for the light amount adjuster to perform the assistance operation; and
a transmitter configured to transmit a notification signal for notifying a condition of the battery portion,
the notification signal contains charge information, which indicates whether or not the battery portion is being charged, and remaining level information, which indicates a power amount stored in the battery portion,
the display device includes:
a receiver configured to receive the notification signal;
an image generator configured to generate a condition image, which represents the condition of the battery portion, in response to the notification signal received by the receiver; and
a display portion configured to display the condition image, and
the image generator generates a power amount image, which represents a power amount stored in the battery portion, as the condition image if the charge information indicates that the battery portion is not being charged.
7 . A video system control method comprising:
communicating a notification signal between a display device, which displays a stereoscopic video, and an eyewear device, which performs an assistance operation that assists in observing the video, in order to notify a condition of the eyewear device; and
causing the display device to generate and display a condition image which represents the condition of the eyewear device in response to the notification signal, wherein
the notification signal contains charge information, which indicates whether or not the eyewear device is being charged, and remaining level information, which indicates a power amount stored in the eyewear device, and
the display device generates and displays a power amount image which represents a power amount stored in the eyewear device as the condition image if the charge information indicates that the eyewear device is not being charged.
