Display device, eyewear device and video system

An eyewear device, comprising:

• a light amount adjuster configured to perform an adjustment operation for adjusting an incident light amount, which is an image light amount that enters a left eye and a right eye from a display device;
• a receiver which receives, from a display device, a control signal for controlling the adjustment operation;
• and
• a controller which controls the light amount adjuster in response to the control signal, wherein
• the control signal includes a timing signal for notifying a timing of a period to increase the incident light amount to the left and right eyes or a stop signal for stopping the adjustment operation,
• the controller controls the adjustment operation of the light amount adjuster in response to the timing signal when the receiver receives the timing signal,
• the controller stops the adjustment operation when the receiver receives the stop signal, and
• the receiver receives the timing signal for a first display mode while an image is displayed in the first display mode by the display device, and then, when the display device switches an image display mode to a second display mode which is different from the first display mode, the receiver receives the stop signal, and then receives the timing signal for the second display mode.

A video system, comprising:

• an eyewear device which performs an adjustment operation to adjust an incident light amount to a left eye and a right eye;
• and
• a display device which switches a display mode between a first display mode for displaying an image that is stereoscopically perceived and a second display mode that is different from the first display mode, wherein
• the display device includes:
• a signal generator which generates a control signal to perform the adjustment operation, the control signal including a timing signal for notifying a timing of a period to increase the incident light amount to the left and right eyes in the first and second display modes or a stop signal for stopping the adjustment operation;
• and
• a transmitter which transmits the control signal to the eyewear device,
• while the image is displayed in the first display mode, the transmitter transmits the timing signal for the first display mode,
• when the display mode is switched from the first display mode to the second display mode, the transmitter transmits the stop signal to the eyewear device, and then transmits the timing signal for the second display mode to the eyewear device,
• the eyewear device includes:
• a light amount adjuster for performing the adjustment operation to adjust the incident light amount, which is an image light amount that enters the left and right eyes from the display device;
• a receiver which receives the control signal for controlling the adjustment operation;
• and
• a controller which controls the light amount adjuster in response to the control signal,
• the controller controls the adjustment operation of the light amount adjuster in response to the timing signal when the receiver receives the timing signal,
• the controller stops the adjustment operation when the receiver receives the stop signal, and
• the receiver receives the timing signal for the first display mode while the image is displayed in the first display mode by the display device, and then, when the display device switches the display mode to the second display mode which is different from the first display mode, the receiver receives the stop signal, and then receives the timing signal for the second display mode.
